Project Location - Specific: 892 Elmira Road, Vacaville, CA 95688 Assessor’s Parcel Number: 0135-030-010 Coordinates: 38º21’04.1”,-121º55’04.9”

Project Location - City: Vacaville Project Location - County: Solano County Lead Agency: City of Vacaville Contact Person: Albert Enault - (707) 449-5364

Description of Project: The project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road, in the City of Vacaville, Solano County, California. The site currently has access via an existing driveway along Leisure Town Road, which is now unsafe due to a roadway expansion project along Leisure Town Road (Jepson Parkway). The new driveway would begin approximately 220 feet west of the Elmira Road/Leisure Town Road intersection, and would provide vehicular access along Elmira Road rather than Leisure Town Road. The entrance would start 30 feet wide and would gradually taper to 10 feet wide within the site for a total length of 192 feet before terminating at an existing asphalt/concrete parking area front along Leisure Town Road.

Environmental & Land Use Setting: The project is located on a 0.48-acre site that is relatively flat with terrestrial habitats consisting of non-native annual grassland, riparian, and developed land. Non-native annual grassland runs through the center of the site with scattered oak trees and elderberry shrubs on either side. The northeastern corner of the site contains the existing driveway, a small parking lot, Well No. 8, and three existing trees slated for removal. A small patch north of the project footprint and the entire southern portion of the site contain riparian habitat, characterized by hydrophilic plants and 32 elderberry shrubs. The elderberry shrubs are a host plant for the federally threatened Valley Elderberry Longhorn Beetle (“VELB). According to CNDDB records, the nearest occurrence of this species is approximately 4.5 miles northwest of the project site. The project site is not within the USFWS designated Critical Habitat for this species. The project would not remove or prune any elderberry shrubs. The only aquatic habitat in the vicinity is Alamo Creek, an intermittent creek outside of the site.

Proposed Mitigated Negative Declaration: Pursuant to the requirements of the California Environmental Quality Act (CEQA), the City has conducted an initial study to evaluate potential environmental impacts of the project. Based on City policies, standard conditions, a technical study prepared for the project and other prior environmental documentation related to the project site and vicinity, the Initial Study concludes that mitigation measures can be incorporated into the project to address potential impacts in the categories of biological resources and cultural resources reducing potential impacts to a less than significant level.

Document Availability: The Initial Study, Draft Mitigated Negative Declaration and all other information related to the project application are available for review at the Planning Division offices located in City Hall at 650 Merchant Street, Vacaville, CA 95688. (Primary Contact – Albert Enault). Also, the document can be accessed using the following URL: https://permits.cityofvacaville.com/eTRAKiT3/Search/project.aspx. Upon navigating to the website, search by “Project_No” using the file number (17-202) to access information on the project file.

CITY OF VACAVILLE iii DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 PROJECT DESCRIPTION AND LOCATION

The project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road (“Project”). The driveway would begin approximately 220 feet west of the Elmira Road/Leisure Town Road intersection, and would provide vehicular access along Elmira Road rather than Leisure Town Road. The entrance would start 30 feet wide and would gradually taper to 10 feet wide within the site for a total length of 192 feet before terminating at an existing asphalt/concrete parking area front along Leisure Town Road. Figure 1 below shows the project site with relation to the Vacaville City Limits.

FIGURE 1. LOCATION MAP

CITY OF VACAVILLE iv DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 Approximately 70 cubic yards of soil would be exported from the site. One dump truck with a 12 cubic yard capacity would require 6 trips from the site to export the excavated soil. Excavated soil would be transported to the Easterly Wastewater Treatment Plant (EWWTP), located approximately 3 miles east in Elmira, CA. The project would excavate approximately 12 inches deep with grading and subbase compacting for new pavement. Equipment required for the work would consist of skid steer loaders, compactors, saw cutters and hand tools. During construction activities would utilize recommendations described in the Biological Report (Attachment 3) for protecting on-site resources. Construction activities are anticipated to being in the fall of 2017 and would require approximately three weeks to complete. Stormwater collected at the site would remain onsite due to natural topography. BMPs would be installed at the site during construction activities to prevent untreated runoff from entering Alamo Creek or the nearby storm drain inlets. All BMPs would be constructed and maintained in accordance with the latest edition of the California Stormwater Quality Association Stormwater Best Management Practices (BMP) Handbook for Construction. Figures 2 and 3 below shows the project with relation to adjoining roadways.

CITY OF VACAVILLE v DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 FIGURE 3. SITE MAP

EXISTING CONDITIONS

The project site (“site”) is a 0.48-acre site located in the northeast corner of 892 Elmira Road in the City of Vacaville, Solano County, California. An existing driveway from Leisure Town Road currently provides access to Well No. 8, operated by the City of Vacaville Utilities Department (“City”). However, the California Department of Transportation (“DOT”) has approved the Jepson Parkway Project, which involves improvements and expansion of Leisure Town Road, rendering the existing driveway to Well No. 8 unsafe. As such, the proposed project is needed to provide the City with safe vehicular access to Well No. 8.

The site is relatively flat with terrestrial habitats consisting of non-native annual grassland, riparian, and developed land. Non-native annual grassland runs through the center of the site with scattered oak trees and elderberry shrubs on either side. The northeastern corner of the site contains the existing driveway, a small parking lot, Well No. 8, two immature trees and one large Almond tree that are slated for removal. A small patch north of the project footprint and the entire southern portion of the site contain riparian habitat, characterized by hydrophilic plants and elderberry shrubs. The only aquatic habitat in the vicinity is Alamo Creek, an intermittent creek outside of the site. The site is located in Solano County, which has a climate generally characterized as Mediterranean with mild, wet winters, and dry, hot summers. The mean annual precipitation is 14-18 inches per year.

CITY OF VACAVILLE vi DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 Soil: According to the National Resource Conservation Service, the site is comprised of entirely of Yolo loam soil (0 to 4 percent slopes) (Natural Resource Conservation Service 2015).

Hydrology: No potentially jurisdictional wetlands or other Waters of the U.S. occur within the site, although Alamo Creek, is an intermittent creek located approximately 20 feet south of the project footprint.

Vegetation: The site contains terrestrial habitats including non-native annual grassland, riparian, and developed land (Well No. 8 and existing parking area). Non-native annual grassland runs through the center of the site with scattered oak trees and elderberry shrubs on either side. The project would require the removal of two immature landscape trees and one large almond tree. A small patch north of the project footprint and the entire southern portion of the site contain riparian habitat, characterized by hydrophilic plants and elderberry shrubs. Approximately 32 elderberry shrubs were identified within the site during the biological survey. The project would require the removal of three existing trees to connect the new driveway with the existing parking area. The trees consist of two small Yew Pines (Podocarpus Mac.) that were planted with the original landscaping in 1999, and one large Almond tree (19-in diameter dbh).

Special-Status Plants: No special-status plant species were observed at the site during a field investigation on November 15, 2016. However, the California Natural Diversity Database (CNDDB) identifies three CNSP-listed species within a 5-mile radius that could occur in nonnative grassland or riparian habitat. The three species include: Baker’s navarretia, Contra Costa goldfields, and two-fork clover.

Special-Status Wildlife: As noted above, the site contains approximately 32 elderberry shrubs, which is a host plant for the federally threatened Valley Elderberry Longhorn Beetle (“VELB). According to CNDDB records, the nearest occurrence of this species is approximately 4.5 miles northwest of the project site. The project site is not within the USFWS designated Critical Habitat for this species. The project would not remove any elderberry shrubs.

No birds were observed nesting within the site. Migratory birds and other birds of prey, such as the Swainson’s hawk, have the potential to nest within the site. Swainson’s hawk have been known to nest in a location just south of the City’s wastewater treatment plant, approximately 1.5 miles east of the site. According to CNDDB records, the nearest occurrence of this species is approximately 829 feet northeast of the site.

No bats were observed roosting within the site. According to the CNDDB records, the Western Red Bat (Lasiurus blossevillii) species has been recorded approximately 13 miles south of the site. However, as this is a migratory species, there is still potential for it to occur on the site. One tree with a large cavity was found approximately 10 feet north of the project footprint during the biological survey. The project would not require the removal of any trees with potential roosting habitat.

SURROUNDING LAND USES

The currently project site is bordered by the following:

North: The northern boundary adjoins Elmira Road. South: The southern boundary adjoins Old Alamo Creek. West: The western boundary adjoins Patwin Park. East: The eastern boundary adjoins Leisure Town Road.

CITY OF VACAVILLE vii DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 OTHER PUBLIC AGENCIES WHOSE APPROVAL IS REQUIRED

This IS/MND would be used by the City, as the Lead Agency, in evaluating the potential environmental impacts of the proposed project. In order for the proposed project to be implemented, a series of actions and approvals would be required from several agencies. Anticipated project approvals/actions would include, but are not limited to, the following:

 Adoption of Environmental Determination (MND): City of Vacaville.  Design Review (DR) approval of a land use permit: City of Vacaville.  U.S. Fish and Wildlife approval via informal consultation.

TRIBAL CONSULTATION

According to the California Indian Tribal Homelands and Trust Land Map produced by the California Department of Water Resources, the City of Vacaville is situated in the ethnographic territory of the Patwin (http://www.water.ca.gov/tribal/maps.cfm). At this time, the Yocha Dehe Wintun Nation is the only regionally affiliated tribe to request notification pursuant to Public Resources Code Section 21080.3.1.

On June 30, 2017, the City of Vacaville notified the Yocha Dehe Wintun Nation (“Nation”), via email and USPS, about the project. According to a response dated July 25, 2017, the Nation did not confirm the presence of known tribal resources at the project site, but rather expressed concern about impacting undiscovered archaeological deposits. Also, their response included a request to contact the Nation’s Cultural Resources Manager to coordinate a date and time for a site visit. Therefore, the City contacted the Nation via email and proposed several dates/times to coordinate a site visit. The City received no response, therefore a second and third email with additional dates/times were sent on August 3, 2017, and August 11, 2017, respectively. The City did not receive a response to those attempts. Finally, on August 22, 2017, the City sent a final response via email and certified mail/return receipt request. No response was received from the Nation. Therefore, in accordance with Section 21080.3.2(b)(2) and 21082.3(d)(2) of the Public Resources Code, the City concluded consultation after acting in good faith and exhibiting reasonable efforts to coordinate consultation with the Nation for the Project. More information on this consultation can be read under Section XVII of the draft Initial Study and Mitigated Negative Declaration.

MITIGATION MONITORING PROGRAM

CEQA allows a lead agency to adopt a mitigated negative declaration when all the impacts identified in the Initial Study are reduced by adopted mitigation measures to a less-than- significant level. The project proponent must agree, before release of the Initial Study, to implement all the mitigation measures identified in the Initial Study to qualify for the mitigated negative declaration. As the project proponents and lead agency, the City and Proponent have reviewed all the mitigation measures identified in this Initial Study and agreed to incorporate all of the measures into the project.

When approving a mitigated negative declaration, Section 21081.6 of the Public Resources Code requires the lead agency to adopt a monitoring program that includes each mitigation measure in the Initial Study that would avoid or mitigate significant environmental effects. A mitigation monitoring program has been prepared and is available upon request. Mitigation measures identified in Table 1 will be adopted to ensure that the project has a less-than- significant impact on the environment.

CITY OF VACAVILLE ix DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 MITIGATION MEASURES

TABLE 1. MITIGATION MEASURES BIO 1 A qualified biologist shall conduct a focused botanical survey prior to commencement of construction activities within the nonnative grassland and riparian habitats for potential on-site special-status species during the blooming periods. One survey between April and June would satisfy the blooming season requirements for all species. A letter report shall be submitted to CDFW and the City within 30 days following the preconstruction survey to document the results. Should no species be observed, then no additional mitigation is required.

a. Should any of these plants be observed during the focused botanical survey, the biologist shall contact the CDFW within one day following the preconstruction survey to report the findings. A buffer shall be established around the species, as determined by a qualified biologist, using construction flagging prior to commencement of construction activities.

Should avoidance of the special-status plant be infeasible, then the CDFW shall be notified at least 10 days prior to commencement of ground-breaking activities to provide the opportunity for CDFW to determine the feasibility, necessity and any requirements to transplant the species from the project site. An additional letter report shall be submitted to the CDFW within 30 days to document the results. BIO 2 Prior to commencing construction, the Applicant shall initiate informal consultation with the USFWS regarding the potential impact on the VELB. Informal consultation shall be initiated by letter and shall include copies of the Biological Report and VELB Effects Analysis Report. The City shall follow the USFWS guidelines and the recommendation of the Biological report to ensure that the project does not adversely impact the VELB. Any additional requirements imposed by the USFWS shall be followed. BIO 3 The following protective measures, consistent with USFWS Conservation Guidelines, shall be implemented prior to commencement of construction activities to avoid adverse effects to VELB habitat within 100 feet of the Project:

a. High visibility construction fencing shall be placed around the elderberry shrubs present within the 100-foot study area. The fencing shall extend to the maximum extent feasible, centered on each elderberry shrub to ensure that the active work area is as far away as possible. Avoidance areas are defined as all areas within the fenced buffer surrounding the elderberry bushes. The construction fencing shall not be removed until construction activities in the vicinity of the avoidance areas have been completed. b. Signs shall be erected approximately 50 feet apart along the high visibility construction fencing within the avoidance areas with the following information: i. “This area is habitat of the valley elderberry longhorn beetle, a threatened species, and must not be disturbed. This species is protected by the FESA of 1973, as amended. Violators are subject to prosecution, fines, and imprisonment.” ii. The signs shall be clearly readable from a distance of 20 feet, and shall be maintained for the duration of construction. c. A qualified biologist shall conduct environmental awareness training for all construction personnel regarding the status of the VELB and the need to protect the elderberry host plant. The training shall include identification of elderberry shrubs, required practices before the start of construction, general measures that are being implemented to conserve these species as they relate to the proposed project, penalties for noncompliance, and boundaries of the buffer area and permitted disturbance zones. Supporting materials containing training information shall be prepared and distributed. Upon completion of training, all construction personnel shall sign a form stating that they have attended the training and understand all the conservation measures. Training shall be conducted in languages other than English, as appropriate. Proof of this instruction shall be kept on file with the contractor. The contractor shall provide the USFWS with a copy of the training materials and copies of the signed forms, indicating that training has been completed within 30 days of the first training session. The qualified biologist shall request that a representative volunteer train and provide training materials to any new crew members that were not present at the first environmental

CITY OF VACAVILLE x DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 awareness training. d. Staging areas shall be located a minimum 30 feet away from all elderberry shrubs. Temporary stockpiling of excavated or imported material shall occur only in approved construction staging areas. Excess excavated soil shall be used onsite or disposed of at a regional landfill or other appropriate facility. e. Standard precautions shall be employed by the construction contractor to prevent the accidental release of fuel, oil, lubricant, or other hazardous materials. f. A litter control program shall be instituted. The contractor shall provide closed garbage containers for the disposal of all food-related trash items (e.g., wrappers, cans, bottles, food scraps). All garbage shall be removed daily. g. Roadways and areas disturbed by project activities within 100 feet of the elderberry shrubs shall be watered at least twice per day to minimize dust emissions. h. Project-related vehicles shall observe a 15 mile-per-hour speed limit within construction areas, except on existing paved roads where they shall adhere to posted speed limits. BIO 4 The following mitigation measures will be implemented to minimize adverse effects to VELB habitat within 20 feet of the project footprint:

a. A qualified biologist shall be available for monitoring or consulting during all construction activities occurring within 20 feet of elderberry shrubs. b. No work shall occur within 20 feet of elderberry bushes from March 15 - June 15 to avoid directly disturbing VELB during their emergence period. c. The Contractor shall ensure that dust control measures (e.g., watering) are implemented in the vicinity of elderberry shrubs. To further minimize adverse effects associated with dust accumulation, elderberry shrubs shall be covered by a protective cloth (i.e., burlap or weed mat) during all ground-disturbing activities occurring within 20 feet. The cloth shall be removed after ground-disturbing activities are completed. The cloth shall extend from the ground upwards a minimum of ten feet along the elderberry shrub. d. No insecticides, herbicides, fertilizers, or other chemicals that might harm VELB or the elderberry shrub shall be used within the project site. e. The Contractor shall provide a written description of how the construction areas are to be restored, protected, and maintained after construction is completed. f. Equipment operators shall refrain from working within ten feet of the dripline of elderberry shrubs along Alamo Creek (Locations 2-5) and six feet of the dripline of the single elderberry shrub north of the Project (Location 1) to the maximum extent practicable. g. Buffer areas shall be restored to pre-project habitat conditions immediately upon the completion of construction. No further development of the road or activities within the buffer areas shall occur. As the driveway’s limited use is for servicing Well No. 8, the City shall post a “Private Use” sign at the entrance to discourage public trespassing. Additionally, the City will maintain at least one VELB disturbance warning sign described above. BIO 5 A qualified biologist shall conduct a concentrated presence/absence survey during peak activity periods (typically one hour before sunset) on each tree with suitable habitat (cavities) for bats. If bats are found to be present, then the qualified biologist shall submit an avoidance plan to the City and CDFW for approval. The avoidance plan shall evaluate the length of time disturbance, equipment noise, and type of habitat present at the project site. BIO 6 A preconstruction survey shall be conducted by a qualified biologist for nesting birds of prey and migratory birds, including Swainson’s Hawk, within 14 days prior to commencement of construction activities that occur between February 1 and October 1. If no active nests are identified during the preconstruction survey, then no further mitigation is required. The qualified biologist shall also document and submit the results of the preconstruction survey in a letter to the CDFW and the City within 30 days following the survey. The letter shall include: a description of the methodology including dates of field visits, the names of survey personnel, and a list of references cited and persons contacted; and a map showing the location(s) of any bird nests observed on the project site.

CITY OF VACAVILLE xi DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 BIO 7 If any active nests are identified during the preconstruction survey within the project site, a buffer zone will be established around the nests. A qualified biologist will monitor nests weekly during construction to evaluate potential nesting disturbance by construction activities. The biologist will delimit the buffer zone with construction tape or pin flags within 250 feet of the active nest and maintain the buffer zone until the end of the breeding season or until the young have fledged. Guidance from the CDFW will be requested for a reduced buffer zone if establishing a 250-foot buffer zone is impractical. Guidance from the CDFW will be requested if the nestlings within the active nest appear disturbed. CUL 1 In the event of the accidental discovery or recognition of any human remains in any location other than a dedicated cemetery, the following steps should be taken:

(1) There shall be no further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent human remains until:

a. The coroner of the county in which the remains are discovered must be contacted to determine that no investigation of the cause of death is required, and b. If the coroner determines the remains to be Native American: i. The coroner shall contact the Native American Heritage Commission within 24 hours. ii. The Native American Heritage Commission shall identify the person or persons it believes to be the most likely descended from the deceased Native American. iii. The most likely descendent may make recommendations to the landowner or the person responsible for the excavation work, for means of treating or disposing of, with appropriate dignity, the human remains and any associated grave goods as provided in Public Resources Code section 5097.98, or

(2) Where the following conditions occur, the landowner or his authorized representative shall rebury the Native American human remains and associated grave goods with appropriate dignity on the property in a location not subject to further subsurface disturbance.

a. The Native American Heritage Commission is unable to identify a most likely descendent or the most likely descendent failed to make a recommendation within 24 hours after being notified by the commission. b. The descendant identified fails to make a recommendation; or c. The landowner or his authorized representative rejects the recommendation of the descendant, and the mediation by the Native American Heritage Commission fails to provide measures acceptable to the landowner. CUL 2 If any cultural or archeological resources are encountered during ground disturbance or subsurface construction activities (e.g., trenching, grading), all construction activities within a 50- foot radius of the identified potential resource shall cease until a Secretary of the Interior qualified archaeologist evaluates the item for its significance and records the item on the appropriate State Department of Parks and Recreation (DPR) 523 series forms. All forms and associated reports will be submitted to the NWIC of the California Historical Resources Information System (CHRIS). The archaeologist shall determine whether the resource requires further study. If, after the qualified archaeologist conducts appropriate technical analyses, the resource is determined to be eligible for listing on the California Register of Historical Resources or as a unique archaeological resource as defined in Public Resources Code Section 15064.5, the archaeologist shall develop a plan for the treatment of the resource. This shall contain appropriate mitigation measures, including avoidance, preservation in place, data recovery excavation, or other appropriate measures, as outlined in Public Resources Code Section 21083.2.

CITY OF VACAVILLE xiii DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 EVALUATION OF ENVIRONMENTAL IMPACTS:

Scope of the Environmental Assessment

This environmental assessment analyzes the project-specific impacts of the Well No. 8 Driveway project in accordance with the requirements of the California Environmental Quality Act (CEQA). The scope of review includes only those improvements associated with the project plans, and as described in the project description.

The method of environmental analysis includes a review to determine whether the impact related to the City’s evaluation criteria would be: potentially significant; less than significant unless mitigation is incorporated; less than significant; or none. The analysis includes a summary of the affected environment and a review of the threshold for determining significance. The evaluation of potential impacts applies the threshold, determines significance and, if necessary, includes recommended mitigation measures to reduce identified impacts to a level of less-than-significant.

Potentially Less Than Less Than No I. AESTHETICS Significant Significant Significant Impact Would the project: Impact With Impact Mitigation Incorporation

a) Have a substantial adverse effect on a scenic

vista?

b) Substantially damage scenic resources, including, but not limited to, trees, rock

outcroppings, and historic buildings within a state scenic highway?

c) Substantially degrade the existing visual character or quality of the site and its surroundings?

d) Create a new source of substantial light or glare, which would adversely affect day or nighttime views in the area?

AFFECTED ENVIRONMENT

The project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road. The driveway would begin approximately 220 feet west of the Elmira Road/Leisure Town Road intersection, and would provide vehicular access along Elmira Road rather than Leisure Town Road. Construction activities would be visible from two 4-lane undivided arterial streets, Leisure Town Road and Elmira Road. According to the Cultural Report (pg. 9), no archaeological resources were discovered during the field survey, and none have been identified by the NAHC. The site contains several

CITY OF VACAVILLE 1 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 mature trees that would be preserved at the site. Three smaller trees would be removed to accommodate the new road alignment. According to the Conservation and Open Space Element of the Vacaville General Plan (pg. COS-24), there are no state-designated scenic highways in Vacaville. In addition, there are no significant rock outcroppings or historic structures located on the site. Image 1 and 2 below shows the view of the site.

IMAGE 1. LEISURE TOWN ROAD

IMAGE 2. ELMIRA ROAD

CITY OF VACAVILLE 2 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 DISCUSSION OF IMPACTS a) Adversely affect a scenic vista? As described in the Conservation and Open Space Element of the Vacaville General Plan (pg. COS-24), most of Vacaville’s scenic resources are associated with the open space, natural resources, and agricultural uses of the Planning Area. Such areas include: (1) riparian corridors, which are habitat and vegetation zones associated with the banks and floodplains of a river, stream, or lake) that run throughout the city; (2) views of the rural and undeveloped lands surrounding the city; and (3) Vacaville’s hillside areas. Many of the scenic resources that are valued by Vacaville residents, such as the ridgelines of the Vaca Mountains and English Hills, are located outside the city limits or even beyond the Planning Area boundary.

The Project will not affect any scenic views, because: (1) the new driveway will be constructed at ground level and will not block visibility of any nearby scenic resource; (2) as described under the project description and “Affected Environment,” the site does not contain any scenic resources and is not located along a State-designated scenic highway. Therefore, the Project will have a no impact on scenic vistas. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? As described in the “Affected Environment,” the site does not contain any scenic resources, rock outcroppings or historic buildings, nor is the project located along a state scenic highway. The project will require the removal of three existing trees to connect the new driveway with the existing parking area. The trees consist of two small Yew Pines (Podocarpus Mac.) that were planted with the original landscaping in 1999, and one large Almond tree (19-in diameter dbh). However, these trees are not considered a scenic resource as defined by the Open Space and Conservation Element of the General Plan (pg. COS-24). Therefore, the project will have no impact on scenic resources. c) Substantially degrade the existing visual character or quality of the site and its surroundings? Please see the “Affected Environment” and “Project Description” sections. The project will not degrade the existing visual character or quality of the site, because: (1) the project has been designed to avoid impacts to on-site Elderberry Shrubs; (2) the Project will not require the removal of any native trees that may require preservation under Section 14.09.131.030.C.2 (Tree Preservation – Permit Require for Tree Removal) of the Land Use and Development Code; and (3) the new driveway would be constructed at ground level, which will not change the visual character of the site. Based on this assessment, the project will have No Impact on the site’s existing visual character or quality. d) Create a new source of substantial light or glare, which would adversely affect day or nighttime views in the area? Please see the “Affected Environment” and “Project Description” sections. The Project will not include any lights. No Impact.

IMPACT CONCLUSION

The Project will not result in impacts to aesthetics.

MITIGATION MEASURES

Potentially Less Than Less Than No II. AGRICULTURAL RESOURCES Significant Significant Significant Impact In determining whether impacts to agricultural resources Impact With Mitigation Impact are significant environmental effects, lead agencies may Incorporation refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state’s inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board. Would the project:

a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to

the Farmland Mapping and Monitoring Program of the California Resources Agency, to non- agricultural use?

b) Conflict with existing zoning for agricultural use,

or a Williamson Act contract?

c) Involve other changes in the existing environment which, due to their location or

nature, could result in conversion of Farmland, to non-agricultural use?

AFFECTED ENVIRONMENT

The Project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road. According to Figure COS-2 (Important Farmlands) of the Conservation and Open Space Element in the Vacaville General Plan, the project site is not designated as Prime Farmland, Farmland of Statewide Importance, Unique Farmland or Grazing Land. According to the Solano County Williamson Act Map (FY 2013/2014) prepared by the Department of Conservation, the site does not contain an active Williamson Act Contract. As a result, the project will have no effect on the City’s agricultural resources.

Would the project:

a) Conflict with or obstruct implementation of the

applicable air quality plan?

b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation?

c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions, which exceed quantitative thresholds for ozone precursors)?

d) d) Expose sensitive receptors to substantial

AFFECTED ENVIRONMENT

The Project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road. According to the Conservation and Open Space Element of the Vacaville General Plan (COS-30), the site is located primarily within the Sacramento Valley AirBasin (SVAB). The prevailing winds in Vacaville are moderate in strength and vary from moist clean breezes from the south to dry land flows from the north. The mountains surrounding the SVAB create a barrier to airflow, which can trap air pollutants under certain meteorological conditions. Surface concentrations of pollutants are highest when stagnant conditions are combined with temperature inversions that trap pollutants near the ground. Air pollutants of concern in Vacaville include ozone (O3), carbon monoxide (CO), nitrogen oxides (NO2 and NOx), sulfur dioxide (SO2), and particulate matter (PM). These pollutants originate from sources both within and outside of Vacaville. For this project, air pollutants of concern would only be generated by construction activities. The project would not produce any air pollutants from long term operational activities.

CITY OF VACAVILLE 6 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 The site is under the jurisdiction of the Yolo-Solano Air Quality Management District (YSAQMD), which is tasked with achieving and maintaining healthful air quality in the project vicinity in accordance with State and Federal standards. YSAQMD has developed an attainment plan for the purpose of bringing the district into compliance with the federal and state ambient air quality standards. The plan includes strategies for progressive reduction of air pollutants by promoting active public involvement, by encouraging compliance through positive influence and behavior, and through public education in both the public and private sectors. YSAQMD also provides a handbook of guidelines for determining air quality thresholds of significance and mitigation measures for proposed development projects that generate emissions from motor vehicles. YSAQMD has identified four pollutants of concern with recommended thresholds of significance for determining whether projects have significant adverse impacts to air quality.

Construction-related emissions associated with typical construction activities were modeled using the California Emissions Estimator Model (CalEEMod), Version 2013.2.2. CalEEMod allows the user to enter project-specific construction information, such as types, number, and horsepower of construction equipment, and number and length of offsite motor vehicle trips. Table 2 provides a brief summary of the potential level of construction and operational pollutants generated by the proposed project. Attachment 6 shows the complete emission calculations for the project, as generated by the CalEEMod software.

TABLE 2. YSAQMD POLLUTANTS OF CONCERN Pollutant Threshold of Significance Construction Operations

Reactive Organic Gases (ROG) 10 tons/year 0.00837 tons/year 0.0092 tons/year

Nitrogen Dioxide (NOx) 10 tons/year 0.074 tons/year 0.00 tons/year

13 lbs/day 0.00 lbs/day Coarse Particulate Matter (PM10) 80 lbs/day (summer/winter) (summer/winter)

Carbon Monoxide (CO) Refer to State Standard1 0.0654 tons/year 0.00002 tons/year Source: YSAQMD 2007. Notes: 1 The state ambient air quality standards for CO are 9.0 parts per million (8-hour standard) and 20 parts per million (1-hour standard).

DISCUSSION OF IMPACTS a) Conflict with or obstruct implementation of the applicable air quality plan? The YSAQMD thresholds of significance for criteria pollutants are applied to evaluate regional impacts of project-specific emissions of air pollutants and their impact on the YSAQMD’s ability to reach attainment. Emissions that are above these thresholds have not been accommodated in the air quality plans and would not be consistent with the air quality plans. As discussed in Section (b), project-related emissions would not exceed the significance thresholds developed by the YSAQMD for construction and operational emissions. Therefore, the project would not conflict with applicable attainment plans, and impacts would be less than significant. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? See “affected environment” above. As confirmed by the CalEEMod calculations, construction emissions and operational emissions are not expected to generate significant levels of pollutants during construction-related activities or operational activities. Construction emissions are expected to be below the significance thresholds. The project will

CITY OF VACAVILLE 7 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 produce no operational emissions. Therefore, impacts from the project’s construction and operational emissions are anticipated to be less than significant. c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? Emissions from construction-related activities such as earthmoving, grading, wind-erosion of exposed soil, and vehicle travel on exposed soil may contribute additional concentrations of PM10. Construction equipment and vehicles also generate exhaust emissions of CO, ROG, NOx, and PM10. While project-generated CO emissions are not expected to exceed YSAQMD standards, short-term construction-related emissions (Ozone and PM10) are expected to increase other regional levels that already violate state and federal standards. The project sponsor has incorporated the following procedures to reduce construction-related emissions: (1) vehicles would not exceed 15 mph; and (2) exposed soil would be watered twice daily to decrease wind erosion and dust. Less-than significant level. d) Expose sensitive receptors to substantial pollutant concentrations? The site is located near existing single-family homes to the south. Project operation would not result in long-term emission sources of Toxic Air Contaminants (TACs). However, construction-related activities would result in temporary onsite emissions of TACs; specifically, diesel PM from off-road heavy-duty equipment exhaust. Activity during project construction may also generate fugitive dust emissions. Due to the variable nature of construction activity, the generation of TAC emissions would be temporary, especially considering the short amount of time such equipment would be close enough to result in the exposure of sensitive receptors to substantial concentrations. Because construction activities would be sporadic, transitory, and short-term in nature, and construction TAC emissions would cease after the completion of project construction, health impacts from these emissions would be less than significant.

Although health impacts from TAC emissions are expected to result in less-than-significant impacts, the project proponent would be required to implement Best Management Practices (BMP) during construction, which would further reduce any less-than-significant effects associated with TAC emissions. These construction BMPs may include:

 Using construction equipment that is properly tuned and maintained in optimum running condition, in accordance with manufacturers’ specifications;  Restricting unnecessary vehicle idling to 5 minutes;  Watering all active construction sites at least twice daily. Frequency should be based on type of operation, soil, and wind exposure;  Hauling trucks shall maintain at least 2 feet of freeboard;  Covering all trucks hauling dirt, sand, or loose materials;  Covering inactive storage piles; and  Sweeping streets if visible soil material is carried out from the construction site. e) Create objectionable odors affecting a substantial number of people? The occurrence and severity of odor impacts depend on numerous factors, including the nature, frequency, and intensity of the source; wind speed and direction; and the presence of sensitive receptors. Although offensive odors rarely cause any physical harm, they still can be very unpleasant, leading to considerable distress and often generating citizen complaints to local governments and regulatory agencies. Project operations are not anticipated to produce odorous emissions. Construction activities associated with the project could result in short-term odorous emissions from diesel exhaust associated with construction equipment. However, these emissions would be intermittent and would dissipate rapidly from the source. In addition, this diesel-powered

CITY OF VACAVILLE 8 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 equipment would only be present on site temporarily during construction activities. Therefore, construction would not create objectionable odors affecting a substantial number of people, the project would not create objectionable odors affecting a substantial number of people, and the impact would be less than significant.

IMPACT CONCLUSION

The Project will have a less than significant impact on air quality.

CITY OF VACAVILLE 10 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 AFFECTED ENVIRONMENT

The Project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road. The project sponsor contracted with Analytical Environmental Services (AES) to evaluate biological resources located at the project site. AES prepared a Biological Resources Evaluation (Attachment 3) and a Valley Elderberry Longhorn Beetle Effects Analysis Report (Attachment 4). The following section discloses that information:

TOPOGRAPHY AND HYDROLOGY

The site is relatively flat with terrestrial habitat and some developed land for Well No. 8 and Patwin Park to the west. According to the National Resource Conservation Service, the site is comprised of entirely of Yolo loam soil (0 to 4 percent slopes) (Natural Resource Conservation Service 2015). According to the Biological Resources Evaluation, there are no potentially jurisdictional wetlands or other Waters of the U.S. within the site. Alamo Creek, an intermittent creek, is located approximately 20 feet south of the project footprint.

VEGETATION

The project site contains terrestrial habitats including non-native annual grassland, riparian, and developed land consisting of the existing Well No. 8 facility and adjoining parking area. The Project would require the removal of three trees adjoining the existing parking area. The trees consist of two small Yew Pines (Podocarpus Mac.) that were planted with the original landscaping in 1999, and one large Almond tree (19 inch dbh). A small patch north of the project footprint and the entire southern portion of the site contain riparian habitat, characterized by hydrophilic plants and elderberry shrubs. Approximately 32 elderberry shrubs were identified within the site during the biological survey.

Special-Status Plants: According to the California Natural Diversity Database (CNDDB), there are three CNSP-listed species within a 5-mile radius that could occur in nonnative grassland or riparian habitat. The three species include: Baker’s navarretia, Contra Costa goldfields, and two-fork clover. None of these special-status plant species were observed at the site during a field investigation.

WILDLIFE

As noted above, the site contains approximately 32 elderberry shrubs, which is a host plant for the federally threatened Valley Elderberry Longhorn Beetle (VELB). The site is not located within a Critical Habitat area as designated by the United States Fish and Wildlife Service. According to CNDDB records, the nearest occurrence of VELB is approximately 4.5 miles northwest of the site The Project would not remove any elderberry shrubs. Figure 4 on the next page identifies five district populations at the site, and Table 3 identifies the number of stems by diameter class, presence of exit holes, and presence of riparian habitat of elderberry shrubs. The majority of shrubs contain indicators of suitable VELB habitat and VELB presence. According to the VELB Effects Analysis Report, approximately 14 elderberry shrubs are within 20 feet of the Project (Locations 1, 2, and 3). Elderberry shrubs in Locations 4 and 5 are situated outside of the 20 foot buffer, but are within 100 feet of construction activities and could be indirectly impacted by project activities. No shrubs would be directly impacted, removed, or trimmed.

AVIAN SPECIES

No birds were observed nesting at the site. Migratory birds and other birds of prey, such as the Swainson’s hawk, have the potential to nest within the site. Swainson’s hawk have been known to nest in a location just south of the City’s wastewater treatment plant, approximately 1.5 miles east of the site. According to CNDDB records, the nearest occurrence of this species is approximately 829 feet northeast of the site. No bats were observed roosting within the site. According to the CNDDB records, the Western Red Bat (Lasiurus blossevillii) species has been recorded approximately 13 miles south of the site. However, as this is a migratory species, there is still potential for it to occur on the site. One tree with a large cavity was found approximately 10 feet north of the project footprint. The Project would not remove any trees with potential roosting habitat.

CITY OF VACAVILLE 12 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 DISCUSSION OF IMPACTS a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or US Fish and Wildlife Service? The Project would create a less-than significant impacts on the following biological resources, with mitigation measures adopted:

Special-Status Plants

The proposed project has the potential to impact the following CNPS-listed plants identified on the CNDDB 5-mile radius map within the nonnative grassland or riparian habitat: Baker’s navarretia, Contra Costa goldfields, and two-fork clover. Therefore, the Project would incorporate Mitigation measure BIO 1 to avoid impacts to these special-status plant species. Less-than significant impact with mitigation measures.

Valley Elderberry Longhorn Beetle (VELB)

According to the Biological Report, the Project is located within 100 feet of 32 existing elderberry shrubs that contain indicators of suitable VELB habitat and VELB presence. The Project will not require the removal or pruning of any elderberry shrubs. According to USFWS Conservation Guidelines, the Project may impact, but is not likely to adversely impact VELB. Mitigation measures BIO 2, 3 and 4 shall be incorporated to ensure the project avoids adverse impacts to VELB habitat within the 100 foot survey area. Less-than significant impact with mitigation measures.

Western Red Bat

Three trees with no potential roosting habitat are proposed for removal along the edge of the existing parking lot. Though removal of trees with potential roosting habitat is not proposed, development of the proposed project would have the potential to indirectly affect Western red bat, a species of special concern, as the project comes within ten feet of potential roosting habitat. One tree with a large cavity was found approximately ten feet north of the project footprint during the biological survey. Disturbance of this tree, due to the proximity of construction, would be a potentially significant impact. Therefore, the Project would incorporate mitigation measure BIO 5 to avoid impacts to bat species. Less-than significant impact with mitigation measures.

Migratory Birds and Other Birds of Prey

The proposed project has the potential to impact nest sites for federally protected migratory birds, including Swainson’s hawk. Therefore, the Project would incorporate mitigation measures BIO 6 and 7 to avoid impacts to nest sites for migratory birds and other birds of prey. Less-than significant impact with mitigation measures. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Game or US Fish and Wildlife Service?

No potentially jurisdictional wetlands or other Waters of the U.S. occur within the project site, although Alamo Creek is located approximately 20 feet to the south. Due to the proposed project’s proximity to Alamo Creek, the Project would incorporate mitigation measure BIO 6 to

CITY OF VACAVILLE 13 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 avoid potential impacts to Alamo Creek. Less-than significant impact with mitigation measures. c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc,) through direct removal, filling, hydrological interruption, or other means? No potentially jurisdictional wetlands or other Waters of the U.S. occur within the project site. No impact. d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? The property is surrounded by parcels that are developed. There is little or no connectivity to other open space areas, and the parcels are not located within any known existing or potential migratory wildlife corridors. The proposed project is unlikely to affect the movement or nursery sites of any native wildlife species. No impact. e) Conflict with any local policies or ordinances protecting biological resources such as a tree preservation policy or ordinance? The Project would require the removal of three trees that do not meet the criteria for preservation under the City’s Tree Preservation Ordinance (Chapter 14.09.131). The removal these trees will not conflict with any local policies or ordinances. No impact. f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? The Solano HCP, of which the City of Vacaville is a participant, has not yet been adopted. Nevertheless, the project site is within an area identified for development within the City of Vacaville’s urban zone (Zone 1). Implementation of the project would not conflict with the long term goals and objectives of the Draft HCP (SCWA 2013), and appropriate mitigation measures have been adapted from the Solano HCP for the proposed project. Based on this evaluation, the project will not conflict with the provisions of the Solano HCP. No impact.

IMPACT CONCLUSION

The proposed project will have a less than significant impact on biological resources, with the following mitigation measures incorporated.

MITIGATION MEASURES

BIO 1: A qualified biologist shall conduct a focused botanical survey prior to commencement of construction activities within the nonnative grassland and riparian habitats for potential on-site special-status species during the blooming periods. One survey between April and June would satisfy the blooming season requirements for all species. A letter report shall be submitted to CDFW and the City within 30 days following the preconstruction survey to document the results. Should no species be observed, then no additional mitigation is required.

CITY OF VACAVILLE 14 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 determined by a qualified biologist, using construction flagging prior to commencement of construction activities. b.

a) Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5?

b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5?

c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?

d) Disturb any human remains, including those

interred outside of dedicated cemeteries?

AFFECTED ENVIRONMENT

The Project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road. The Project would excavate approximately 12 inches deep with grading and subbase compacting for new pavement. Equipment required for the work would consist of skid steer loaders, compactors, saw cutters and hand tools. The project sponsor contracted with Analytical Environmental Services (AES) to evaluate cultural resources located at the site. AES prepared a Cultural Resources Summary Report (Attachment 5). AES completed a record search at the Northwest Information Center (NWIC) as well as reviewed pertinent historical topographic maps and surveyor’s plats. NWIC records showed one previously recorded cultural resource within a ¼-mile radius of the proposed project. No resources have been documented within the site.

In addition to the records search, AES completed a field survey that included approximately 50 feet on either side of the proposed driveway. The entire area was inspected using parallel pedestrian transects spaced at ten meter intervals or less. Thick spring grasses obscured the ground surface, leaving less than one percent ground surface visibility. Along the parcel edges bordering Leisure Town Road and Elmira Road, ground visibility was clear as weed control left a strip up to three feet wide almost entirely bare of vegetation. No archaeological resources were discovered during the field survey, and none have been identified by the Native American Heritage Commission (NAHC).

However, the presence of Alamo Creek on the southern border of the site does increase the potential for as-yet undiscovered buried archaeological sites that could be uncovered during project construction. Therefore, the Project will incorporate mitigation measures CUL-1 and CUL-2 to reduce the potential impacts for accidental discovery to a less-than significant level.

CITY OF VACAVILLE 18 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 DISCUSSION OF IMPACTS a) Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5? Neither the records searches at the NWIC and NAHC nor the field survey identified historical resources in or immediately adjacent to the site. Therefore, no mitigation measures for built-environment historical resources are necessary. No Impact. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? There is the potential, although low, that archaeological deposits that qualify as archaeological resources under CEQA could be encountered during project construction. Such deposits, should they qualify as archaeological resources, could be disturbed by project construction, which could result in a significant impact under CEQA Guidelines §15064.5. Implementation of mitigation measure CUL-1, described below, would reduce impacts to previously undiscovered resources to a less-than-significant level. Mitigation measure CUL-1 would mitigate this potential impact to a less-than-significant level by incorporating impact avoidance in the project work program. In the event that avoidance is not possible, the project will treat the potential loss of a sensitive resource by recovering, through documentation or excavation, the scientifically consequential data contained in the deposit that would otherwise be lost due to construction-related disturbance. In this way, the damage to the resource would be offset by the realization of its data potential. Less than significant impact with mitigation measures incorporated. c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? The site is not known to contain any unique paleontological resources or geological features. However, if any are found during site construction activities, work will cease in accordance with CEQA Section 15064.5(e)(f). Less than significant impact. d) Disturb any human remains, including those interred outside of dedicated cemeteries? No human remains were identified in the project area. Although unlikely, should unidentified human remains be encountered during ground disturbance, their disturbance could result in a significant impact under CEQA. Therefore, the Lead Agency will implement mitigation measure CUL-2, which would mitigate this potential impact to a less-than-significant level by incorporating impact avoidance in the project work program. In the event that avoidance is not possible, the project will treat the potential disturbance of human remains in accordance with the regulatory requirements of the procedures in the cultural report, which parallel the core requirements of California Health and Safety §7050.5. This treatment would address the disposition of the remains in a way that respectfully incorporates the wishes of the descendant community representatives. Less than significant impact with mitigation measures incorporated.

IMPACT CONCLUSION

The Project will have a less than significant impact on Cultural Resources, with the following mitigation measures incorporated.

CITY OF VACAVILLE 19 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 MITIGATION MEASURES

CUL-1: In the event of the accidental discovery or recognition of any human remains in any location other than a dedicated cemetery, the following steps should be taken:

(1) There shall be no further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent human remains until:

CUL-2: If any cultural or archeological resources are encountered during ground disturbance or subsurface construction activities (e.g., trenching, grading), all construction activities within a 50-foot radius of the identified potential resource shall cease until a Secretary of the Interior qualified archaeologist evaluates the item for its significance and records the item on the appropriate State Department of Parks and Recreation (DPR) 523 series forms. All forms and associated reports will be submitted to the NWIC of the California Historical Resources Information System (CHRIS). The archaeologist shall determine whether the resource requires further study. If, after the qualified archaeologist conducts appropriate technical analyses, the resource is determined to be eligible for listing on the California Register of Historical Resources or as a unique archaeological resource as defined in Public Resources Code Section 15064.5, the archaeologist shall develop a plan for the treatment of the resource. This shall contain appropriate mitigation measures, including avoidance, preservation in place, data recovery excavation, or other appropriate measures, as outlined in Public Resources Code Section 21083.2.

The Project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road. The site is relatively flat with terrestrial habitats consisting of non-native annual grassland, riparian, and developed land. Non- native annual grassland runs through the center of the site with scattered oak trees and elderberry shrubs on either side. The City of Vacaville is situated between two seismically active regions: the San Francisco Bay region and the Central Valley region. As a result a nearby earthquake could cause ground shaking at the site. The City’s General Plan Safety Element identifies the Vaca- Kirby Hills Fault System as the only fault system that passes through the Vacaville. According to the National Resource Conservation Service, the site is comprised entirely of Yolo loam soil (0 to 4 percent slopes) (Natural Resource Conservation Service 2015). Figure 5 below shows the probably placement of soil on the site.

CITY OF VACAVILLE 22 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 DISCUSSION OF IMPACTS a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving:

i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? The California Geological Survey (CGS) establishes regulatory zones (known as Earthquake Fault Zones or Alquist-Priolo Zones) around the surface traces of active faults, and issues maps to all affected cities, counties, and State agencies for use in planning and controlling development. The maps provided by CGS is shown in Figure SAF-1 (Regional Faults) of the Vacaville General Plan. According to the Vacaville General Plan, the Vaca-Kirby Hills Fault system is the only fault system that passes through the Vacaville Planning Area. The Vaca Fault has not experienced displacement within the past 11,700 years, and there is no evidence for displacement along the Kirby Hills Fault during the last 700,000 years. The Green Valley Fault system, which lies 12 miles to the southwest of Vacaville, has been active within the past 200 years. The site is not located on any known faults. The Project would not increase on-site human population or increase the frequency of visitations to Well No. 8. Therefore, impacts from fault-rupturing is expected to be less-than significant. ii) Strong seismic ground shaking? Vacaville is located within a seismically active region and earthquakes have the potential to cause ground shaking of significant magnitude. Impacts created by strong seismic ground shaking is expected to be less-than significant because the parking improvements will be designed consistent with all seismic related Building Code requirements intended to protect structures and inhabitants from potential dangers of strong seismic shaking. Less than significant impact. iii) Seismic-related ground failure, including liquefaction? According to Figure SAF-2 (Liquefaction Potential) of the Vacaville General Plan, the site is located in an area with medium susceptibility to liquefaction. On-site improvements will be designed consistent with all seismic related Building Code requirements intended to protect workers from potential dangers of ground failure. Less than significant impact. iv) Landslides? According to the Figure SAF-3 (Historic Mapped Landslides) of the Vacaville General Plan, the site is not located in an area susceptible to landslides. Therefore, there will be no impacts from landslides. No impact. b) Result in substantial soil erosion or the loss of topsoil? According to Figure SAF-4 (Percent Slope) and Figure SAF-3 (Historic Mapped Landslides), the site is not located in a hillside area and is not susceptible to landslides. Based on this information, the site is not expected to experience significant water/gravity erosion during construction-related activities. The site may be susceptible to wind erosion during construction activity, which could affect the loss of topsoil. However, this impact is expected to be less-than significant because the project sponsor will incorporate Best Management Practices to reduce wind erosion. Impacts from soil erosion or the loss of topsoil is expected to be less-than-significant. c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? See “Affected Environment” and Sections “a” and “b” above. The site is not located in an area susceptible to landslides. However, the site has a medium susceptibility to liquefaction. Prior to obtaining a Building Permit, the project sponsor will be required to provide a geotechnical study, which will contain recommendations to reduce impacts associated with liquefaction. Less-than significant impact.

No expansive soil was identified in the geotechnical exploration report. Site preparation practices described in the report would be implemented during construction, such as compaction, surcharging, and use of engineered fill that would reduce the potential for hazards related to expansive soils. Facilities constructed as part of the project would be required to comply with recommendations included in the geotechnical report prepared for the project, and satisfy applicable building and related codes that include requirements related to expansive soils to minimize potential hazards to life and property. Therefore, a less-than-significant impact would occur. e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? Please see the “Affected Environment” section. Septic tanks are not proposed as part of the project. No Impact.

a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Cause a substantial increase in cumulative greenhouse gas emissions?

b) Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases?

AFFECTED ENVIRONMENT

The Project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road. The project is located in the Yolo-Solano Air Quality Management District (YSAQMD). Less-than significant impacts associated with GHG emissions will be generated from short-term construction activities, including the operation of off-road equipment, materials transport, and worker commutes during construction. The finished driveway would not generate any new GHG emissions.

As described in the Conservation and Open Space Element of the Vacaville General Plan (pg. COS-24), a balance of naturally occurring gases in the atmosphere determines the earth’s climate by trapping solar heat through a phenomenon known as the greenhouse effect. Greenhouse gases (GHGs), including carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and water vapor, keep solar radiation from exiting our atmosphere. In a process very similar to the windows on a greenhouse, GHGs trap so much heat that the temperature within the earth’s atmosphere is rising. Emissions from human activities, such as electricity production, motor vehicle use, and agriculture, are contributing to the concentration of GHGs in the atmosphere and have led to a trend of unnatural warming of the earth’s climate, which is known as global warming.

REGULATORY SETTING

The California State Legislature has proposed and the Governor has approved laws and policies to reduce the amount of Greenhouse Gas (GHG) generated each year. Global Warming Solutions Act (AB 32), passed in 2006, requires statewide GHG emissions in California be reduced to 1990 levels by the year 2020 and requires the California Air Resources Board (CARB) to adopt rules and regulations to achieve this goal. The CARB has developed the Climate Change Scoping Plan (Scoping Plan), which is California’s roadmap to reach the GHG reduction goals required in AB 32. The Scoping Plan has several strategies and recommended measures to reduce GHG emissions. The City’s General Plan includes several City-wide policies that address the objective of reducing local emissions and thereby addressing the potential increase in GHG emissions because the City recognizes the need to address global climate change.

CITY OF VACAVILLE 25 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 In addition, the YSAQMD has identified certain Greenhouse Gases such as Ozone, Carbon Monoxide (CO), and Coarse Particulate Matter (PM10) as pollutants of concern for this region. Ozone is a regional air pollutant created primarily by motor vehicles, solvents, and farming operations in Solano County. The majority of Carbon Monoxide (CO) in the County comes from motor vehicles. Demolition and construction activities and road dust from vehicle traffic are the largest contributors to particulate matter 10 microns or less in diameter (PM10) in the County. YSAQMD has determined that the project region is considered to be non-attainment with State and Federal Ozone standards, attainment with the State and Federal CO standards, non-attainment with the State PM10 standard, and attainment with the Federal PM10 standard.

METHODOLOGY

The project-specific impacts on GHGs were analyzed and measured using project region recommended thresholds of significance for the aforementioned pollutants of concern. The project-level thresholds of significance were established by YSAQMD for PM10, CO and the precursors to Ozone, which are Reactive Organic Gases (ROG) and Nitrogen Oxide (NOx). Construction-related and operations-related GHG emissions were estimated using California Emissions Estimator Model (CalEEMod); results have been included as Attachment 6. GHG emissions associated with project construction were estimated using CO2 emissions as a proxy for all GHG emissions. The primary sources of proposed project-related GHG emissions are anticipated to be combustion of fossil fuels from the operation of internal combustion engines used during project construction (e.g., portable equipment, off road equipment, and vehicles).

DISCUSSION OF IMPACTS a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Cause a substantial increase in cumulative greenhouse gas emissions? The project is expected to generate GHG emissions from short- term construction related activities. Specifically, off-road equipment, materials transport, and worker commutes during construction of the project would generate GHG emissions. Total project construction and operational GHG emissions were estimated using the methodology discussed earlier under Air Quality.

The YSAQMD currently has not established a threshold of significance for construction or operation-related GHG emissions. To establish additional context in which to consider the project’s GHG emissions, this analysis reviewed guidelines used by other air quality management districts. BAAQMD has adopted GHG significance thresholds of 1,100 MTCO2e per year or 4.6 MTCO2e per year per Service Population (total of residents and employees) (BAAQMD 2011). As shown in Table 4, total annual unmitigated GHG emissions would be 8.6866 MTCO2e, and the service population metric for the project would be 0 MTCO2e per year per Service Population; 0 persons was assumed because the project consists of a new driveway. Annual project GHG emissions and the project service population metric would not exceed the BAAQMD thresholds. Therefore, impacts from project GHG emissions would be less than significant.

Project GHG efficiency-based metric (MTCO2e/year/SP) 0 Notes:

MTCO2e = million metric tons of carbon dioxide equivalents MTCO2e/year/SP = million metric tons of carbon dioxide equivalents per year per service population b) Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases? In 2015, the City of Vacaville adopted an Energy and Conservation Strategy to address the reduction of major sources of GHG emissions. An emission target was adopted of 21.7 percent below Vacaville’s 2020 business as usual forecast. To meet this goal, the City of Vacaville adopted communitywide measures to reduce emissions. Communitywide measures include the following sectors: transportation and land use, green building, renewable energy and low carbon fuels, energy conservation, water and wastewater, solid waste, parks, open space and agriculture, purchasing, and community action. The project would not conflict with any applicable plans, policies, or regulations adopted for the purpose of reducing GHG emissions. Therefore, the impact would be less than significant.

IMPACT CONCLUSION

Greenhouse Gas Emissions produced by the Project will have a less than significant impact the environment.

HAZARDOUS MATERIALS

According to the State Water Resources Control Board GeoTracker database (SWRCB 2016) and the Department of Toxic Substances Control EnviroStor database (DTSC 2016), the site does not contain any leaking underground storage tanks sites. Also, the site has not been used to store hazardous waste and substances. Neither database identified any existing or past clean-up efforts for the site.

AIRPORT HAZARDS

The Nut Tree Airport is located approximately 2.3 miles southeast of the site. According to Figure 14.09.134-1 (Nut Tree Airport Compatibility Map) of the Vacaville Land Use and Development Code, the site does not reside in any compatibility zones, which confirms airport activities will not impact the project. Travis Air Force Base is also located approximately 5.6 miles south of the site. According to Figure 2A (Compatibility Zones) from the Travis Air Force Base Land Use Compatibility Plan (2002), the site resides within Zone D which has building height restrictions. The project will not conflict with the restrictions imposed by Zone D, because the driveway will be constructed at ground level.

WILDFIRE HAZARDS

According to Figure SAF-9 (CALFIRE Hazard Severity Zones) of the Vacaville General Plan, the site is not located in an area where wildfires are a threat. According to Figure PUB-1 (Fire Protection Service Providers) of the Vacaville General Plan, emergency services will be provided by the Vacaville Fire Department (VFD), which includes the following coverage: fires, emergency medical incidents, public assists, traffic and vehicle accidents, and other emergency situations. The closest fire station is Station 72 located at 2001 Ulatis Drive, which is approximately 1.4 miles northwest of the site as the vehicle drives.

DISCUSSION OF IMPACTS a) Create a public health hazard through the transport, use, or disposal of hazardous materials? Please see “Affected Environment”. Construction and operational activities will not require the routine transport, use, or disposal of hazardous materials. Some hazardous materials, such as gasoline, will be used during construction activities, but this is not expected to create a significant hazard to the public or environment. Less than significant impact. b) Create a public hazard through upset or accident involving the release of hazardous materials? As discussed under Section (a) above, the project would involve the use of hazardous materials during construction, such as gasoline for refueling vehicles. The project sponsor would store, label, and dispose of hazardous materials in accordance with applicable federal, state, and local regulations; and would be responsible for reporting any accidental discharges of hazardous materials or other similar substances (where amounts are above the

CITY OF VACAVILLE 29 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 threshold for reportable quantities). Operational activities will not require the storage of any hazardous materials at the site. Therefore, the potential for significant hazards related to hazardous materials would be less than significant. c) Emit hazardous emissions or involve handling hazardous materials within one-quarter mile of an existing or proposed school? No existing or planned elementary, middle/intermediate, or high school is within 0.25 mile (1,320 feet) of the project site. Therefore, no impact would occur. d) Be located on a site that is listed as hazardous by CAL-EPA? Please see “Affected Environment”. The site is not included on any list of hazardous materials sites. Therefore, no impact would occur. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? Please see “Affected Environment”. The project would not increase safety hazards for people residing or working in the project area. No impact. f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? There are no private airstrips within the vicinity of the project. No impact. g) Impair implementation of an adopted emergency response or emergency evacuation plan? The project would not impact any emergency response or evacuation plans adopted by the City or County. As determined by the Vacaville Fire and Police Departments, adequate emergency ingress and egress will be provided for the site, and will be designed to comply with the access requirements of the Fire Department. No impact. h) Expose people or structures to risk, loss, injury, or death involving wildland fires? According to the Safety Element of the Vacaville General Plan (pg. SAF-20), the California Department of Forestry (CDF) has developed a Fire Hazard Severity Scale that utilizes three criteria in order to evaluate and designate potential fire hazards in wildland areas. The criteria are fuel loading (vegetation), fire weather (winds, temperatures, humidity levels, and fuel moisture contents), and topography (degree of slope). Figure SAF-9 (CALFIRE Hazard Severity Zones) in the Safety Element shows the Fire Hazard Severity Zones for the City of Vacaville. According to Figure SAF-9, the project site is not located in any areas considered to have moderate or high fire hazard severity. No impact.

IMPACT CONCLUSION

The Project will have a less than significant impact on hazard and hazardous materials.

AFFECTED ENVIRONMENT

CLIMATE AND DRAINAGE

As described in the Vacaville General Plan (pg. I-6), the site is located southeast of the English Hills formation, and east of the Vaca Mountain Range. The region is within the Mediterranean climate characterized by dry, warm to hot summers, with wet, cool winters. Located on the edge of the Bay Area, Vacaville occasionally experiences the cooling influence of marine air spilling through the Carquinez Strait during the otherwise warm spring, summer, and early fall. Winters are at times foggy and cold, but snow is exceedingly rare. In general, creeks in Vacaville flow in an east-southeasterly direction and ultimately drain into the Sacramento River via Cache Slough. The southern portion of Vacaville drains either to the Noonan Drain, which discharges ultimately to Barker Slough, or to Union Creek, which discharges to Suisun Bay.

DAMS AND RESERVOIRS

There are two existing reservoirs in Vacaville: (1) Lagoon Valley Lake; and (2) Basherini Reservoir. The Lagoon Valley Lake is a tributary to Laguna Creek, draining a portion of Lower Lagoon Valley, and is located 4.46 miles southwest. The Basherini Reservoir is located 3.17 miles northwest along Vine Street, which is owned and operated by the Solano Irrigation District. According to Figure SAF-7 (Dam Inundation Areas) of the Vacaville General Plan, the northeastern portion of Vacaville is subject to potential dam inundation by the Monticello Dam. The site is not located in this inundation area, and will not be affected by these existing dams.

FLOOD ZONE

According to Figure SAF-6 (FEMA Flood Zones) of the Vacaville General Plan, the site does not reside within a 100-year or 500-year flood zone. According to Federal Emergency Management Agency (FEMA) Map 06095C0281E, the site is located just north of a floodway

FIGURE 6. FEMA FLOOR ZONE MAP

DISCUSSION OF IMPACTS a) Violate any water quality standards or waste discharge requirements? Pollutants related to short-term construction activity may include leaking fuel and oil from construction equipment, which has the potential to decrease water quality. During construction, erosion control measures and BMPs would be implemented to minimize the effects of erosion, sedimentation, and leakage of vehicle and equipment fluids. Erosion control measures would include mulching, temporary seeding, using wattles, and adding silt fencing. The contractor will be required to comply with federal, state, and local requirements and guidelines to meet water quality objectives for water discharge, including the NPDES General Construction Permit. As proposed, no substantial change would occur in the quality of the stormwater discharge from the project. Impacts on water quality or waste discharge from project construction and operation would be less than significant. b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g. the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which

CITY OF VACAVILLE 33 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 permits have been granted)? The project will not require the use of groundwater resources. Although the driveway will increase impervious surfaces at the site, the additional surface would not interfere substantially with groundwater recharge. The project will have a less than significant on groundwater. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site? The project will not interfere with the adjoining intermittent creek, Alamo Creek. The project would make minor alterations to the some surface area at the site, however, the improvements will not substantially affect on-site drainage. The project will create a less than significant impact on existing drainage patterns on the site. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site? Please see the section (c) above. The project will not affect the adjoining creek or nearby drainage system. The project will not substantially increase the rate or amount of surface runoff. Less than significant impact. e) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? As confirmed by the City of Vacaville Public Works Department, the adjoining infrastructure has been designed to accept any new runoff created by the new driveway. The driveway may create small increases of runoff due to the new impervious surfaces on the site. However, these increases will be negligible and will not result in a significant impact. Less than significant impact. f) Otherwise substantially degrade water quality? As discussed on Section (a), construction of the project would result in less-than-significant impacts to water quality or waste discharge requirements, groundwater supplies or recharge, drainage patterns, and runoff. Therefore, the project is expected to result in less than significant water quality impacts. g) Place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? Please see the “Affected Environment” section, the project site is not located within a 100-year flood hazard area. Therefore, the project will not place nearby development within a 100-year flood hazard area. No impact. h) Place within a 100-year flood hazard area structures which would impede or redirect flood flows? Please see the “Affected Environment” section. As discussed in item (g) above, the project site is not located in a 100-year flood hazard area. Therefore, the proposed structure will not impede or redirect flood flows. No impact. i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? Please see the “Affected Environment” section. The site is not located within a flood plan or inundation area. No impact. j) Inundation by seiche, tsunami, or mudflow? See “Affected Environment” section and section (i) above. The project will not be susceptible to seiches, tsunamis, or mudflows. No impact.

b) Result in the loss of availability of a locally- important mineral resource recovery site

delineated on a local general plan, specific plan or other land use plan?

AFFECTED ENVIRONMENT

The Project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road. The site is relatively flat with terrestrial habitat and some developed land for Well No. 8 facility and adjoining parking area, and Patwin Park to the west. According to the U.S. Geological Survey, the Vacaville Planning Area contains limited mineral resources that are being extracted. Near the southern boundary of the Planning Area in the vicinity of Cement Hill, limestone deposits show evidence of some historic use. Stone quarries in the Vaca Mountains produced dimensioned and ornamental stone. Although the western hills contain sandstone and conglomerates which may be used for sands, gravel, and stone, none of these resources are currently being mined. Commercial extraction is not expected within the planning period, therefore policies and land use designations for mineral resource areas are not included in the General Plan. The site has not been designated by the Vacaville General Plan as an area containing mineral resources. Therefore, development of the project site will have no impact on mineral resources in the region.

DISCUSSION OF IMPACTS a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? Please see the “Affected Environment” section. No impact. b) Result in the loss of availability of a locally-important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan?

AFFECTED ENVIRONMENT

CITY OF VACAVILLE 39 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 Sensitive Receptors

As described in the Noise Element of the Vacaville General Plan (pg. NOI-1), noise is generally defined as unwanted sound. Noise consists of any sound that may produce physiological or psychological damage and/or interfere with communication, work, rest, recreation, or sleep. Noise is especially a concern in the vicinity of noise-sensitive uses, which are generally defined as locations where people reside or where the presence of unwanted sound could adversely affect the use of land. For the purpose of this project, sensitive receptors are defined as people(s) who will be exposed to noise created by the project during construction hours and during normal operating hours. The level of threshold for measures noise impacts is derived from Section 14.09.127.120 (Noise) of the Vacaville Land Use and Development Code, which states that exterior noise levels shall not exceed 50 dBavg between 7:00 am and 10:00 pm, and 45 dBavg between 10:00 pm and 7:00 am for residences, transient lodging (motels and hotels), hospital and nursing homes.

The project site is not located next to any transient lodging or hospitals. However, existing single- family residential units are located just south and east of the site. According to Google Maps, the nearest building is approximate 160 ft. away from the site across Old Alamo Creek. Due to proximity, these residences would normally be impacted by non-transportation sources listed below. The following sections describe noise levels produced by the project.

Non-Transportation Sources

Non-transportation noise can originate from two sources: construction activities and operational activities. Due to the nature of the project, no noise is expected during operational activities, therefore the project will produce no impact from operational noise sources. As noted above, short term construction activities will produce some noise that could impact adjoining single-family residence. The project will require the use of common construction equipment such as skid steer loaders, compactors, saw cutters and hand tools. According to the Construction Noise Handbook from the U.S. Environmental Protection Agency (fhwa.dot.gov), the following noise levels are expected for common construction equipment:

TABLE 5. NOISE LEVELS FROM COMMON CONSTRUCTION EQUIPMENT Construction Equipment Typical Sound Pressure Level at 50 ft. (dba) Compactor 83 Front End Loader 80 Dump Truck 84 Excavator 85 Paver 85 Source: EPA, Table 9.1 RCNM Default Noise Emission Reference Levels and Usage Factors

According to Table 5, equipment used for construction will produce noise levels that exceed maximum noise levels for sensitive receptors. However, these noise levels are not expected to create a significant impact to adjoining single-family residential land uses for a few reasons. First, the project site and surrounding properties are already inundated by existing noise produced by Leisure Town Road and Elmira Road. As shown on Figure NOI-1 (Existing Noise Level Contours) of the Vacaville General Plan, day/night exterior noise levels for surrounding properties range between 60 db to 70 db, which exceed noise levels prescribed by the City of Vacaville Municipal Code. Figure 7 below shows the noise contours for the project site in more detail.

CITY OF VACAVILLE 40 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 FIGURE 7. EXISTING NOISE CONTOUR LEVELS

Source: Vacaville General Plan (2015).

Second, the closest single-family residence is located approximately 160 ft. away from the project site boundary, and is separated by dense riparian vegetation and trees. Given the noise attenuation provided between the project site and residences, noise levels arriving at sensitive receptors are expected to be negligible as compared to existing ambient noise levels generated by the freeway. Finally, the project sponsor will be required to comply with Section 14.09.127.090 (Performance Standards – Hours of Construction) of the Land Use and Development Code (Municipal Code), which prohibits the operation of grading equipment and construction related activity within 500 feet from any occupied residences between dusk (one-half hour after sunset) and 7:00 a.m., from Monday through Saturday. In addition, no such activities shall be allowed on Sundays or holidays, except for interior work which will not create noise or disturbance noticeable to a reasonable person of normal sensitivity in the surrounding neighborhood. Based on this evaluation, the Lead Agency has concluded that construction-related noise will have a less-than significant impacts on adjoining properties.

Transportation Sources

The site is near transportation sources that generate noise: Leisure Town Road and Elmira Road. However, noise produced by these sources are expected to have no impact on the project because the land use will remain a City facility. Furthermore, traffic generated during construction activity is expected to be less than significant due to the size of the project. Therefore, impacts associated with transportation sources are expected to have no impact on the site.

CITY OF VACAVILLE 41 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 DISCUSSION OF IMPACTS a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Please see the “Affected Environment” section. The project will not introduce new sensitive receptors. The project sponsor will be required to comply with the hours of construction denoted in the Vacaville Land Use and Development Code. Less than significant impact. b) Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels? Please see the “Affected Environment” section. Short-term construction activities have a small potential to generate groundborne vibrations and noise levels. However, these activities will be limited and restricted to day-time hours that have been established by the Vacaville Land Use and Development Code. Less than significant impact. c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? Please see the “Affected Environment” section. The site will remain as a City facility. Less-than significant impact. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Please see the “Affected Environment” section above. Construction-related activities are expected to produce temporary noise. However, the temporary noise is not expected to create a substantial increase as compared to existing ambient noise levels. Less-than significant impact. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? Please see the “Affected Environment” section above. No impact. f) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? The project site is not located in the vicinity of a private airstrip. No impact.

In addition, VPD oversees the Reserve Officer and Cadet Programs and administers specialty units. The project site will be served through one main VPD police station, which is located at 660 Merchant Street, adjacent to Vacaville City Hall. VPD is currently meeting or exceeding its adopted standards for response times. No impact.

Schools: As noted under the Public Facilities and Services Element of the Vacaville General Plan (pg. PUB-7), the City of Vacaville does not have jurisdiction over local schools. The City of Vacaville is served mainly by the Vacaville Unified School District (VUSD) and the Travis Unified School District (TUSD). However, a portion of the city is located within the Dixon Unified School District (DUSD), and a small portion of the Lower Lagoon Valley area falls within the jurisdiction of the Fairfield-Suisun Unified School District (FSUSD).

The proposed land use will have no impact on existing school services. No impact.

Parks: According to the Parks and Recreation Element of the Vacaville General Plan (pg. PR- 1), the City of Vacaville is currently served through a variety of parks and recreation facilities that are categorized into size basic categories: neighborhood parks, community parks, regional parks, accessible open space, special purpose facilities, and bikeways, multi-use trails, and nature trails. In addition, the local school districts own and operate a number of fields and specialized facilities that, in some cases, are made available for public use through policies set by the individual school district. There are also many privately owned recreational facilities in Vacaville, such as golf courses; swim, tennis, and fitness clubs; ice skating and hockey rinks; bowling alleys; and equestrian centers. The locations of the city’s parks are illustrated in Figure PR-1 (Park Location Map) of the Vacaville General Plan. The proposed land use will have no impact and the City’s park facilities. No impact.

Other public facilities: According to the Public Facilities and Services Element of the Vacaville General Plan (pg. PUB-11), the City of Vacaville owns and/or operates numerous public buildings in the city, including City Hall, a public works corporation yard, remote City offices at the corner of Buck Avenue and Eldridge Street, and the Easterly Waste Water Treatment Plant. City Hall is located at 650 Merchant Street. The facility provides for governance and administrative functions, such as the City Council, City Manager, City Attorney, Finance Department, and the City Clerk, and also houses the administrative offices of multiple City departments, including Community Development, Police, Fire, and Public Works. The Public Works corporation yard is located at 1001 Allison Drive, just east of Downtown Vacaville. It provides facilities for municipal building, engineering, and maintenance, and public works functions. The remote City offices located at the corner of Buck Avenue and Eldridge Street house the City’s Community Services and Housing Services departments. The Easterly Waste Water Treatment Plant, which is discussed further in the wastewater section of this Element, is located at 6040 Vaca Station Road and treats wastewater collected in the city.

CITY OF VACAVILLE 47 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 AFFECTED ENVIRONMENT

The Project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road. The Project is consistent with the existing Public Park General Plan designation and the development standards for the Community Facility Zoning District. Since the Project is estimated to generate no additional trips, which is significantly less than an allowable Community Facility zoning, the Project would not result in a change to the existing or the future level of service to the area roadway network. Therefore relative to transportation impact, a finding can be made that the Project would not be impacted for this use.

DISCUSSION OF IMPACTS a) Conflict with an applicable plan, ordinance or policy establishing measures of effectiveness for the performance of the circulation system, taking into account all modes of transportation including mass transit and non-motorized travel and relevant components of the circulation system, including but not limited to intersections, streets, highways and freeways, pedestrian and bicycle paths, and mass transit? Please see “Affected Environment” section about. The project would not expand existing City facilities at the site, therefore the project would not generate additional traffic. No impact. b) Conflict with an applicable congestion management program, including, but not limited to level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways? The Project is not anticipated to generate additional AM or PM Peak Hour trips, because the Project will create a new driveway to provide safer access to the City’s existing facility at the site. No direct significant impact to level of service will result from the Project and the Project will not contribute to cumulative transportation impacts. No impact. c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? The project does not reside under the air traffic patterns from the Nut Tree Airport. However, the site is located under Zone D of the Travis Air Force Base compatibility plan. Zone D imposes restrictions on building height. The project will not conflict with air traffic patterns from TAFB because the project would be constructed at ground level, and the project will not create any additional trips to the site. The Project is proposed in an area with existing roadway improvements and is not developing additional roadway improvements. No impact. d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? The Project will be developed consistent with Federal, State and Local Standards. No changes to roadways are proposed beyond developing the Project in conjunction with existing access roadway. Access improvements will be conditioned to be constructed consistent with City Engineering standards. Therefore the Project will not increase hazards due to design. No impact. e) Result in inadequate emergency access? The Project is located within an existing area designed consistent with local emergency access policy, standards and requirements. The Project proposes to include provisions for emergency vehicle access consistent with local standards. No impact. f) Result in inadequate parking capacity? No additional parking is required.

AFFECTED ENVIRONMENT

The Project includes the construction of a new 10 foot wide driveway and access road for the City’s existing water well facility (Well No. 8) located at 892 Elmira Road. As mentioned under Section V (Cultural Resources) above, a cultural resources study was conducted for the proposed project area (Attachment 5), which confirmed the absence of known historical or cultural remains.

Therefore, in accordance with Section 21080.3.2(b)(2) and 21082.3(d)(2) of the Public Resources Code, the City concluded consultation after acting in good faith and exhibiting reasonable efforts to coordinate consultation with the Nation for the project. The Lead Agency has determined that mitigation measures under Section V (Cultural Resources) will adequately address any potential impacts to undiscovered archaeological deposits. The project will not impact any known tribal cultural resources as defined under Section 5020.1(k), Section 5024.1(c) of the Public Resources Code.

CITY OF VACAVILLE 52 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017 AFFECTED ENVIRONMENT

Water Service

As described in the Public Utilities and Services Element of the Vacaville General Plan (pg. PUB- 19), the City’s distribution system consists of one main pressure zone, which primarily serves development with building pad elevations between 82 and 222 feet, and several upper pressure zones, which serve development above 222 feet. The system includes approximately 292 miles of distribution pipelines, including 18-inch, 24-inch, and 30-inch transmission mains, as well as 4-inch to 12-inch water distribution mains. In addition, water is stored by the City in various elevated storage reservoirs, including five reservoirs in the main zone and three reservoirs in the upper pressure zones. The project will not require any water services.

Wastewater

As described in the Public Utilities and Services Element of the Vacaville General Plan (pg. PUB- 22), the City owns and operates the wastewater collection system in Vacaville, which consists of gravity and pressure sewers, lift stations, and associated facilities. The City performs routine wastewater collection system flow monitoring at various permanent metering locations throughout the city and at the Easterly Wastewater Treatment Plant (EWWTP). Additionally, the City maintains a collection system model for the purpose of simulating peak flow conditions in major sewers to determine existing and future needs for collection system improvements. Based on this model, the City uses Development Impact Fees to replace undersized facilities, giving priority to those facilities that are expected to reach capacity in the near future. The project will not require any wastewater services.

Solid Waste and Recycling

As described in the Public Utilities and Services Element of the Vacaville General Plan (pg. PUB- 16), the City of Vacaville contracts with a private waste collection company to provide weekly solid waste, green waste, and recyclable material collection to Vacaville residents and commercial businesses. The California Department of Resources Recycling and Recovery (CalRecycle) has allocated the City of Vacaville with a disposal rate target of 6.5 pounds of waste per person per day. In 2010, the City of Vacaville’s disposal rate was 4.9 pounds of waste per person per day, which was well below the CalRecycle target. The project will not require any solid waste or recycling services.

Storm Drain Services

As described in the Safety Element of the Vacaville General Plan (pg. SAF-9), the City of Vacaville uses a variety of flood control facilities and measures to address flooding problems. As shown in Figure SAF-5 (Existing and Proposed Drainage Facility) of the Safety Element, the City has built several regional detention basins that reduce the flow from the Vaca Mountains before they reach the city in order to reduce urban flooding. The City also maintains a network of storm drains, and works to keep channel flowlines free from debris and vegetation. As part of past flood control efforts, certain creekways have been engineered to handle larger volumes of stormwater than they would in their natural states. The project site is served by existing infrastructure located along Elmira and Leisure Town Road. The project will not require any new offsite improvements.

CITY OF VACAVILLE 53 DRAFT MITIGATED NEGATIVE DECLARATION WELL NO. 8 DRIVEWAY SEPTEMBER 2017

Other Services

Pacific Gas and Electric (PG&E) will provide natural gas and electricity to the project site. Service is provided through underground pipelines and above ground transmission lines. AT&T, US Sprint, MCI, and Pacific Bell all provide telecommunications services to Vacaville. These services are also provided via underground and aboveground transmission lines. The project will not require any other services.

SUBJECT: WELL 8 DRIVEWAY – PROJECT DESCRIPTION 892 Elmira Road (APN 0135-030-100)

PROJECT DESCRIPTION

The proposed development would construct a new driveway on an approximately 0.48-acre site located at 892 Elmira Road (“Project”) for the purpose of providing vehicular access to a City water well facility (Well 8). The driveway would begin approximately 220 feet west of the Elmira Road/Leisure Town Road intersection. The entrance would start 30 feet wide and would gradually taper to 12 feet wide within the site for a total length of 192 feet before terminating at an existing asphalt/concrete parking area front along Leisure Town Road.

Approximately 70 cubic yards of soil would be exported from the site. One dump truck with a 12 cubic yard capacity would require 6 trips from the site to export the excavated soil. Excavated soil would be transported to the Easterly Wastewater Treatment Plant (EWWTP), located approximately 3 miles east in Elmira, CA. The project would excavate approximately 12 inches deep with grading and subbase compacting for new pavement. Equipment required for the work would consist of skid steer loaders, compactors, saw cutters and hand tools. During construction activities would utilize recommendations described in the Biological Report for protecting on-site resources. Construction activities are anticipated to being in the fall of 2017 and would require approximately three weeks to complete.

Stormwater collected at the site would remain onsite due to natural topography. BMPs would be installed at the site during construction activities to prevent untreated runoff from entering Alamo Creek or the nearby storm drain inlets. All BMPs would be constructed and maintained in accordance with the latest edition of the California Stormwater Quality Association Stormwater Best Management Practices (BMP) Handbook for Construction.

FIGURE 1. LOCATION MAP

FIGURE 2. SITE MAP

EXISTING CONDITIONS

The project is located in the northeast corner of 892 Elmira Road in the City of Vacaville, Solano County, California. An existing driveway from Leisure Town Road currently provides access to Well 8, operated by the City of Vacaville Utilities Department (“City”). However, the California Department of Transportation (“DOT”) has approved the Jepson Parkway Project, which involves improvements and expansion of Leisure Town Road, rendering the existing driveway to Well 8 unsafe. As such, the proposed project is needed to provide the City with safe vehicular access to Well 8.

The project site is relatively flat with terrestrial habitats consisting of non-native annual grassland, riparian, and developed land. Non-native annual grassland runs through the center of the project site with scattered oak trees and elderberry shrubs on either side. The northeastern corner of the project site contains the existing driveway, a small parking lot, Well 8, and three immature trees slated for removal. A small patch north of the project footprint and the entire southern portion of the project site contain riparian habitat, characterized by hydrophilic plants and elderberry shrubs. The only aquatic habitat in the vicinity is Alamo Creek, an intermittent creek outside of the project site.

Soil: According to the National Resource Conservation Service, the project site is comprised of entirely of Yolo loam soil (Natural Resource Conservation Service 2015).

Hydrology: No potentially jurisdictional wetlands or other Waters of the U.S. occur within the project site, although Alamo Creek, a USGS blue-line stream, is an intermittent creek located approximately 20 feet south of the project footprint. Since the proposed project is less than one acre and is not part of a larger common plan of development a Stormwater Pollution Prevention Plan (SWPPP) is not required. The project would include mitigation measures to reduce impacts to this waterway to less than significant levels.

Vegetation: The project site contains terrestrial habitats including non-native annual grassland, riparian, and developed land (Well 8 and existing parking area). Non-native annual grassland runs through the center of the project site with scattered oak trees and elderberry shrubs on either side. The project would require the removal of three immature trees. A small patch north of the project footprint and the entire southern portion of the project site contain riparian habitat, characterized by hydrophilic plants and elderberry shrubs. Approximately 32 elderberry shrubs were identified within the project site during the biological survey.

Special-Status Wildlife: As noted above, the project site contains approximately 32 elderberry shrubs, which is a host plant for the federally threatened Valley Elderberry Longhorn Beetle (“VELB). According to CNDDB records, the nearest occurrence of this species is approximately 4.5 miles northwest of the project site. The project site is not within the USFWS designated Critical Habitat for this species. Although the project will not remove any elderberry shrubs, there is still potential to impact VELB habitat.

No birds were observed nesting within the project site. Migratory birds and other birds of prey, such as the Swainson’s hawk, have the potential to nest within the project site. Swainson’s hawk have been known to nest in a location just south of the City’s wastewater treatment plant, approximately 1.5 miles east of the project site. According to CNDDB records, the nearest occurrence of this species is approximately 829 feet northeast of the project site.

No bats were observed roosting within the project site. According to the CNDDB records, the Western Red Bat (Lasiurus blossevillii) species has been recorded approximately 13 miles south of the project site. However, as this is a migratory species, there is still potential for it to occur on the project site. One tree with a large cavity was found approximately 10 feet north of the project footprint during the biological survey. The project would not require the removal of any trees with potential roosting habitat.

RE: Biological Resources Evaluation – City of Vacaville Utilities Department Well 8 Driveway Project

The following technical memorandum examines potential effects to biological resources associated with the City of Vacaville Utilities Department Well 8 Driveway Project, located in the City of Vacaville, Solano County, California (Figure 1), Assessor’s Parcel Number 0135030010 (Figure 2).

PROJECT DESCRIPTION

The project is located in the northeast corner of 892 Elmira Road in the City of Vacaville, Solano County, California (project site). The project includes the construction of a new driveway on Elmira Road (proposed project), beginning approximately 220 feet west of the intersection with Leisure Town Road. An existing driveway from Leisure Town Road currently provides access to Well 8, operated by the City of Vacaville Utilities Department (City). However, the California Department of Transportation has approved the Jepson Parkway Project, which involves improvements and expansion of Leisure Town Road, rendering the existing driveway to Well 8 unsafe. As such, the proposed project is needed to provide the City with safe vehicular access to Well 8. The new driveway has a centerline length of 197 feet and width of 12 feet (project footprint). Figure 3 shows the limits of proposed construction.

METHODOLOGY

AES biologist David Moldoff conducted a biological resources survey of the project site on November 15, 2016. The survey consisted of pedestrian level observations while documenting any occurrence of potentially jurisdictional Waters of the U.S. State and federally listed species and/or their habitats. A list of regionally occurring State and federally listed species was compiled based on records obtained from the California Natural Diversity Database (CNDDB), California Native Plant Society (CNPS), and U.S. Fish and Wildlife Service (USFWS) for the following nine U.S. Geological Survey (USGS) 7.5 minute topographic quadrangles: Allendale, Birds Landing, Denverton, Dixon, Dozier, Elmira, Fairfield North, Fairfield South, Mt. Vaca (Attachment 1). A five-mile radius around the project site was also utilized to further refine the analysis of species with the potential to occur in the vicinity. The potential for each of

It should be noted that the survey was not conducted during the typical bloom period for most special-status plants. Therefore, the potential for special status plants to occur onsite is determined based on habitat requirements. The name, regulatory status, habitat requirements, and period of identification for these potential regionally occurring special-status species are identified in Table 1.

ENVIRONMENTAL SETTING

During the November 15, 2016 biological survey, the following terrestrial habitats were identified within the survey area: non-native annual grassland, riparian, and developed (Figure 4). Non-native annual grassland runs through the center of the project site with scattered oak trees and elderberry shrubs on either side. The northeastern corner of the project site contains the existing driveway, a small parking lot, Well 8, and the three immature trees slated for removal. A small patch north of the project footprint and the entire southern portion of the project site contain riparian habitat, characterized by hydrophilic plants and elderberry shrubs. The only aquatic habitat in the vicinity is Alamo Creek, an intermittent creek outside of the project site. Views of the project site are shown in Figure 5.

Waters of the U.S.

A potential wetlands and Waters of the U.S. survey was performed for the project site and the surrounding vicinity during the November 15, 2016 site visit. No aquatic features were identified within the project footprint boundaries, although Alamo Creek, a USGS blue-line stream, is an intermittent creek located approximately 20 feet south of the project footprint. Appropriate mitigation measures for this habitat are identified below that will reduce potential impacts to less than significant levels.

SPECIAL STATUS SPECIES

For the purposes of this assessment, special status has been defined to include those species that are:  Listed as endangered or threatened under the FESA (or formally proposed for, or candidates for, listing);  Listed as endangered or threatened under the CESA (or proposed for listing);  Designated as endangered or rare, pursuant to California Fish and Game Code (§1901);  Designated as fully protected, pursuant to California Fish and Game Code (§3511, §4700, or §5050);  Designated as species of concern to the California Department of Fish and Wildlife (CDFW); or,  Defined as rare or endangered under CEQA.

Table 1 provides a summary of special-status species with the potential to occur on the project site based on habitat types observed during the November 15, 2016 biological survey. Special status species identified on the CNDDB 5-mile radius map that have suitable habitat within the project site are discussed in detail below the table.

While most sightings within 5 miles would be considered historic there is one observation in the CNPS database from 2010 located approximately 2.5 miles north of the project site. Though this species was not observed during the biological survey, appropriate mitigation measures are identified below that will reduce potential impacts to this species to less than significant levels.

Contra Costa goldfields (Lasthenia conjugens) Federal Status – Endangered State Status – None Other – CNPS 1B.1

Contra Costa goldfields is an annual herb with yellow flowers in the composite family (Asteraceae). It occurs in vernal pools, cismontane woodland, valley and foothill grassland, and alkaline playa habitats. It has been found at elevation up to 470 meters above mean sea level. The known range of Contra Costa goldfields includes Alameda, Contra Costa, Mendocino*, Monterey, Marin, Napa, Santa Barbara*, Santa Clara*, Solano and Sonoma Counties. Its blooming period extends from March to June (CNPS, 2016).

While multiple sightings within 5 miles would be considered historic, the CNDDB database contains two observations, one from 2006 and the other from 2007, approximately 4.5 miles south of the project site. Though this species was not observed during the biological survey, appropriate mitigation measures are identified below that will reduce potential impacts to this species to less than significant levels.

Two-fork clover (Trifolium amoenum) Federal Status – Endangered State Status – None Other – CNPS List 1B.1

Previously thought extinct, the two-fork clover was rediscovered in 1993 and 1996. The species is an annual member of the legume (Fabaceae) family with heads of purple flowers with white tips. The two- fork clover occurs in coastal bluff scrub, valley and foothill grassland, sometimes in serpentine soils. It also sometimes occurs in disturbed areas. It is known to occur at elevations ranging from 5 to 415 meters

Analytical Environmental Services 23 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Technical Memorandum – Biological Resources Evaluation above sea level. It is distributed in the southern North Coast Ranges and San Francisco Bay Area, having been documented in Sonoma, Napa, Marin, Solano, and Santa Clara counties. This plant blooms from April to June (CNPS, 2016).

While multiple sightings within 5 miles would be considered historic the CNPS database contains one observation from 2000 approximately 1 mile east of the project site. Though this species was not observed during the biological survey, appropriate mitigation measures are identified below that will reduce potential impacts to this species to less than significant levels.

Special Status Wildlife

Valley Elderberry Longhorn Beetle (Desmocerus californicus dimorphus) Federal Status – Threatened State Status – None

The valley elderberry longhorn beetle (VELB) is completely dependent on its host plant, elderberry (Sambucus spp.), in and around California's Central Valley during its entire life cycle (USFWS, 2006). VELB larvae live within the soft pith of the elderberry where they feed for one to two years. Adults emerge from pupation inside the wood of elderberry shrubs during the spring as the plant begins to flower. The adults feed on the elderberry foliage up until they mate. Females lay their eggs in the crevices of elderberry bark. Upon hatching the larvae then tunnel into shrub stems and feed there. VELB typically utilize stems that are greater than one inch in diameter at ground level (USFWS, 2006). Due largely to the loss of riparian habitat within California's Central Valley, the VELB populations in the state had decreased to a point that in 1980 the USFWS listed the species as threatened pursuant to the FESA.

The nearest CNDDB record of this species is approximately 4.5 miles northwest of the project site. Additionally, the project site is not within the USFWS designated Critical Habitat for this species. However, 32 elderberry shrubs were identified within the project site during the biological survey. Appropriate mitigation measures are identified below that will reduce potential impacts to this species to less than significant levels.

Western Red Bat (Lasiurus blossevillii) Federal Status – None State Status – Species of Special Concern

The western red bat is found throughout California, west of the Sierra Nevada and Cascade crest and deserts, from Shasta County south to Mexico. This species roosts in forests and woodlands from sea level to mixed conifer forests. Roosts are commonly solitary in trees near streams, fields, or urban areas. Edges or habitat mosaics with water are the most suitable habitats. This species is migratory. In California, the western red bat will migrate short distances between summer and winter ranges and can be found in unusual habitats during this time. Hibernation takes place during the coolest months when temperatures drop below 68 °F. Young are born from late May through early July (CDFW, 2006).

Analytical Environmental Services 24 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Technical Memorandum – Biological Resources Evaluation The nearest CNDDB record of this species is approximately 13 miles south of the project site. However, as this is a migratory species, there is still potential for it to occur on the project site. Appropriate mitigation measures are identified below that will reduce potential impacts to this species to less than significant levels.

Swainson’s hawk (Buteo swainsoni) Federal Status – None State Status – Threatened

Swainson’s hawks arrive to their breeding grounds in the Central Valley in early March. They often nest peripherally to valley riparian systems as well as utilizing lone trees or groves of trees in agricultural fields. Valley oak, Fremont cottonwood, walnut, and large willow trees, ranging in height from 41 to 82 feet, are the most commonly used nest trees in the Central Valley (CDFG, 2003). Breeding pairs construct nests composed of sticks, leaves, and bark. Eggs are laid from mid- to late-April and are incubated into mid- May when young begin to hatch. Young remain near the nest and depend on the adults for approximately four weeks after fledging until they permanently leave the breeding territory. Nesting occurs from March 1 to August 15. Swainson’s hawks feed primarily on small mammals, birds, and insects. Young are fed rodents, rabbits, and reptiles. When not breeding, however, this hawk is atypical because it is almost exclusively insectivorous (England et al.1997). Typical foraging habitat includes annual grasslands, alfalfa, and other dry farm crops that provide suitable habitat for small mammals. Suitable foraging habitat nearby nesting sites is critical for fledgling success.

Swainson’s hawk have been known to nest in a location just south of the City’s wastewater treatment plant, approximately 1.5 miles east of the project site and the nearest CNDDB record of this species is approximately 829 feet northeast of the project site. As such, appropriate mitigation measures are identified below that will reduce potential impacts to this species to less than significant levels.

Migratory Birds and Birds of Prey

Fish and Game Code 3503.5 protects all birds in the orders Falconiformes and Strigiformes (collectively known as birds of prey). The Migratory Bird Treaty Act (MBTA) protects migratory birds and other birds of prey, including the great egret (Ardea alba), the American peregrine falcon (Falco peregrines anatum), and the white-tailed kite. Migratory birds and other birds of prey have the potential to nest in shrubs within the project site. No birds were observed nesting within the project site during the November 2016 biological survey. Migratory birds and other birds of prey, such as the Swainson’s hawk, have the potential to nest within the project site.

IMPACTS AND MITIGATION MEASURES

Waters of the U.S.

No potentially jurisdictional wetlands or other Waters of the U.S. occur within the project site, although Alamo Creek is located approximately 20 feet to the south. Since the proposed project is less than one

Analytical Environmental Services 25 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Technical Memorandum – Biological Resources Evaluation acre and is not part of a larger common plan of development a Stormwater Pollution Prevention Plan (SWPPP) is not required.

Due to the proposed project’s proximity to Alamo Creek, the following mitigation measures are recommended to avoid potential impacts:

 SWPPP practices such as, but not limited to, the use of natural fiber rolls or matting, rootwad revetments, stacked stone, etc. shall be employed to reduce potential impacts to Waters of the U.S.

 To the extent feasible proposed construction activities that would occur within the vicinity of Waters of the U.S. outside of the project boundary shall be conducted during the dry season (i.e., April 15 through October 15) to further reduce sedimentation within the watershed.

Special Status Plants

The proposed project has the potential to impact the following CNPS-listed plants identified on the CNDDB 5-mile radius map within the nonnative grassland or riparian habitat: Baker’s navarretia, Contra Costa goldfields, and two-fork clover. The following mitigation measures are required to avoid impacts to these species:

 A qualified biologist shall conduct a focused botanical survey prior to commencement of construction activities within the nonnative grassland and riparian habitats for potential on-site special-status species during the blooming periods. One survey between April and June would satisfy the blooming season requirements for all species. A letter report shall be submitted to CDFW and the City within 30 days following the preconstruction survey to document the results. Should no species be observed, then no additional mitigation is required.

o Should any of these plants be observed during the focused botanical survey, the biologist shall contact the CDFW within one day following the preconstruction survey to report the findings. A buffer shall be established around the species, as determined by a qualified biologist, using construction flagging prior to commencement of construction activities.

o Should avoidance of the special-status plant be infeasible, then the CDFW shall be notified at least 10 days prior to commencement of ground-breaking activities to provide the opportunity for CDFW to determine the feasibility, necessity and any requirements to transplant the species from the project site. An additional letter report shall be submitted to the CDFW within 30 days to document the results.

Special Status Wildlife Valley Elderberry Longhorn Beetle (Desmocerus californicus dimorphus) (VELB)

The proposed project has the potential to impact VELB habitat, although will not remove or come within five feet of an elderberry shrub. Within 100 feet of the project site, 32 elderberry shrubs were found, the majority containing indicators of suitable VELB habitat and VELB presence.

Analytical Environmental Services 26 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Technical Memorandum – Biological Resources Evaluation The following protective measures will be implemented prior to commencement of construction activities to avoid adverse effects to VELB habitat within the 100 foot survey area.

 High visibility construction fencing will be placed around the elderberry shrubs present within the 100-foot study area. The fencing shall extend to the maximum extent feasible, centered on each elderberry shrub to ensure that the active work area is as far away as possible. Avoidance areas are defined as all areas within the fenced buffer surrounding the elderberry bushes. The construction fencing will not be removed until construction activities in the vicinity of the avoidance areas have been completed.  Signs will be erected approximately 50 feet apart along the high visibility construction fencing within the avoidance areas with the following information: “This area is habitat of the valley elderberry longhorn beetle, a threatened species, and must not be disturbed. This species is protected by the FESA of 1973, as amended. Violators are subject to prosecution, fines, and imprisonment.” The signs should be clearly readable from a distance of 20 feet, and must be maintained for the duration of construction.  A biologist will conduct an environmental awareness training to instruct all construction personnel crews about the status of the VELB and the need to protect its elderberry host plant. The training will include identification of special status species, required practices before the start of construction, general measures that are being implemented to conserve these species as they relate to the proposed project, penalties for noncompliance, and boundaries of the survey area and of the permitted disturbance zones. Supporting materials containing training information will be prepared and distributed. Upon completion of training, all construction personnel will sign a form stating that they have attended the training and understand all the conservation measures. Training will be conducted in languages other than English, as appropriate. Proof of this instruction will be kept on file with the contractor. The contractor will provide the USFWS with a copy of the training materials and copies of the signed forms by project staff indicating that training has been completed within 30 days of the completion of the first training session. The biologist will request that a representative volunteer train and provide training materials to any new crew members that were not present at the first environmental awareness training. Copies of signed forms will be submitted monthly as additional training occurs for new employees.  Staging areas will be located as far away as possible from elderberry shrubs and at least 30 feet from them. Temporary stockpiling of excavated or imported material will occur only in approved construction staging areas. Excess excavated soil will be used onsite or disposed of at a regional landfill or other appropriate facility.  Standard precautions will be employed by the construction contractor to prevent the accidental release of fuel, oil, lubricant, or other hazardous materials.  A litter control program will be instituted. The contractor will provide closed garbage containers for the disposal of all food-related trash items (e.g., wrappers, cans, bottles, food scraps). All garbage will be removed daily.  Roadways and areas disturbed by project activities within 100 feet of the elderberry shrubs will be watered at least twice a day to minimize dust emissions.  Project-related vehicles will observe a 15 mile-per-hour speed limit within construction areas, except on existing paved roads where they shall adhere to posted speed limits.

Analytical Environmental Services 27 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Technical Memorandum – Biological Resources Evaluation The following mitigation measures will be implemented to minimize adverse effects to VELB habitat within 20 feet of the proposed project:

 No work will occur within 20 feet of elderberry bushes from March 15 - June 15 to avoid directly disturbing VELB during their emergence period.  The contractor will ensure that dust control measures (e.g., watering) are implemented in the vicinity of elderberry shrubs. To further minimize adverse effects associated with dust accumulation, elderberry shrubs will be covered by a protective cloth (i.e., burlap or weed mat) during all ground-disturbing activities occurring within 20 feet. The cloth will be removed after ground-disturbing activities are completed. The cloth will extend from the ground upwards a minimum of 10 feet along the elderberry shrub.  No insecticides, herbicides, fertilizers, or other chemicals that might harm VELB or the elderberry shrub will be used within the survey area.  Equipment operators will refrain from working within 10 feet of the dripline of the elderberry shrubs along Alamo Creek and 6 feet of the dripline of the elderberry shrub north of the proposed project to the maximum extent practicable.  Buffer areas will be restored to pre-project habitat conditions immediately upon the completion of construction. No further development of the road or activities within the buffer areas will occur. As the driveway’s limited use is for servicing Well 8, the City will post a “Private Use” sign at the entrance to discourage public trespassing. Additionally, the City will maintain at least one VELB disturbance warning sign described above.

Western Red Bat (Lasiurus blossevillii)

Three immature trees with no potential roosting habitat are proposed for removal along the edge of the existing parking lot. Though removal of trees with potential roosting habitat is not proposed, development of the proposed project would have the potential to indirectly affect Western red bat, a species of special concern, as the project comes within ten feet of potential roosting habitat. One tree with a large cavity was found approximately ten feet north of the project footprint during the biological survey. Disturbance of this tree, due to the proximity of construction, would be a potentially significant impact. However, with maintenance of the buffer zone discussed above and implementation of the following mitigation measures, impacts would be less than significant.

 A qualified biologist shall conduct a concentrated presence/absence survey during peak activity periods (typically one hour before sunset) on each tree with suitable habitat (cavities) for bats. If bats are found to be present, then the qualified biologist shall submit an avoidance plan to the City and CDFW for approval. The avoidance plan shall evaluate the length of time disturbance, equipment noise, and type of habitat present at the project site.

Migratory Birds and Other Birds of Prey

The proposed project has the potential to impact nest sites for federally protected migratory birds, including Swainson’s hawk. The following mitigation measures are required to avoid impacts to nest sites for migratory birds and other birds of prey:

Analytical Environmental Services 28 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Technical Memorandum – Biological Resources Evaluation  A preconstruction survey shall be conducted by a qualified biologist for nesting birds of prey and migratory birds, including Swainson’s Hawk, within 14 days prior to commencement of construction activities that occur between February 1 and October 1. If no active nests are identified during the preconstruction survey, then no further mitigation is required. The qualified biologist shall also document and submit the results of the preconstruction survey in a letter to the CDFW and the City within 30 days following the survey. The letter shall include: a description of the methodology including dates of field visits, the names of survey personnel, and a list of references cited and persons contacted; and a map showing the location(s) of any bird nests observed on the project site.

 If any active nests are identified during the preconstruction survey within the project site, a buffer zone will be established around the nests. A qualified biologist will monitor nests weekly during construction to evaluate potential nesting disturbance by construction activities. The biologist will delimit the buffer zone with construction tape or pin flags within 250 feet of the active nest and maintain the buffer zone until the end of the breeding season or until the young have fledged. Guidance from the CDFW will be requested for a reduced buffer zone if establishing a 250-foot buffer zone is impractical. Guidance from the CDFW will be requested if the nestlings within the active nest appear disturbed.

11/10/2016 9:52 AM IPaC v3.0.9 Page 8 IPaC Trust Resources Report Wetlands

Wetlands in the National Wetlands Inventory Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes.

For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers District.

DATA LIMITATIONS The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland boundaries or classification established through image analysis.

The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping problems.

Wetlands or other mapped features may have changed since the date of the imagery or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site.

DATA EXCLUSIONS Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery.

DATA PRECAUTIONS Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities.

Valley Elderberry Longhorn Beetle Effects Analysis Report – City of Vacaville Utilities Department RE: Well 8 Driveway Project

The following technical memorandum examines potential effects on the Valley Elderberry Longhorn Beetle associated with the City of Vacaville Utilities Department Well 8 Driveway Project, located in the City of Vacaville, Solano County, California (Figure 1).

INTRODUCTION

Analytical Environmental Services (AES) prepared this Valley Elderberry Longhorn Beetle (Desmocerus californicus dimorphus; VELB) Analysis Report (Report) for the City of Vacaville Utilities Department Well 8 Driveway Project. The project includes the construction of a new driveway for improved access to Well 8 (proposed project) operated by the City of Vacaville Utilities Department (City). This Report identifies appropriate avoidance and minimization measures to prevent adverse impacts on or incidental take of the federally listed threatened VELB during construction of the proposed project. The Report has been prepared pursuant to Section 10 of the Federal Endangered Species Act (FESA) (16 U.S.C. 1536 (c)) and in accordance with the U.S. Fish and Wildlife Service (USFWS) Conservation Guidelines for Valley Elderberry Longhorn Beetle (USFWS Conservation Guidelines; 1999). As host plants for the VELB, the USFWS Conservation Guidelines recommend that data be collected for all elderberry (Sambucus mexicana) shrubs located within 100 feet of proposed projects. The survey area for this Report includes the proposed driveway site and a minimum buffer of 100 feet around the proposed driveway location.

PROJECT LOCATION

The project is located in the northeast corner of 892 Elmira Road, Assessor’s Parcel Number 0135030010 (project site), at the intersection of Elmira Road and Leisure Town Road in the City of Vacaville, Solano County, California (Figure 2). The 13.5-acre parcel is bordered by Elmira Road, Leisure

The project site is in Township 6 North, Range 1 West, Unsectioned Area of Elmira, U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle.

PROJECT DESCRIPTION

The proposed project is the construction of a new driveway on Elmira Road, beginning approximately 220 feet west of the intersection with Leisure Town Road. An existing driveway from Leisure Town Road currently provides access to Well 8, operated the City. However, the California Department of Transportation has approved the Jepson Parkway Project, which involves improvements and expansion of Leisure Town Road, rendering the existing driveway to Well 8 unsafe. As such, the proposed project is needed to provide the City with safe vehicular access to Well 8. The new driveway has a centerline length of 197 feet and width of 12 feet (project footprint). Figure 3 shows the limits of proposed construction.

METHODOLOGY

On November 15, 2016, AES conducted a VELB survey on the project site, consistent with USFWS Conservation Guidelines. According to USFWS Conservation Guidelines, complete avoidance of VELB is assumed with maintenance of a 100-foot construction buffer around elderberry shrubs. Therefore, data was collected for all elderberry shrubs located within 100 feet of the project footprint. Potential habitat for VELB is defined as an elderberry shrub with at least one stem measuring one inch or greater in diameter at ground level (dgl). As such, the VELB survey included the following:

 Identifying all elderberry shrub locations and measuring the dgl of each stem;

 Estimating the elderberry shrub dripline, defined as the outermost circumference of the shrub canopy where water drips to the ground;

 Documenting each elderberry shrub’s occurrence within riparian or non-riparian habitat; and

 Visual confirmation of VELB exit holes (external evidence of beetle presence) on any stems greater than one inch dgl.

Data collected during the survey is presented in Table 1 below. Each elderberry shrub and dripline location was mapped using a Trimble Geo XT geographic positioning system receiver. Data was then downloaded in a Geographic Information System. All elderberry shrubs and driplines within 100 feet from the project footprint are shown on Figure 4. Site photographs are shown in Figure 5.

ENVIRONMENTAL SETTING

The following terrestrial habitats were identified within the survey area: annual grassland, riparian, and developed. The only aquatic habitat in the vicinity is Alamo Creek, an intermittent creek outside of the project footprint.

Five distinct populations (Locations 1 through 5) containing multiple individual elderberry shrubs were identified and investigated during the VELB survey (Table 1; Figure 4). All stems meeting this criteria were thoroughly searched for beetle exit holes. Location 1 is closest to the proposed project and contains one elderberry shrub comprised of seven stems measuring one-inch or greater. This elderberry shrub is separated from Locations 2 through 5 by a short strip of grassland, approximately 20 feet across (Figure 4). The stems at Location 1, meeting the requirement for potential VELB habitat, were investigated and found to contain beetle exist holes. Locations 2 through 5 all occur along Alamo Creek, within the riparian corridor (Figure 4). Location 2 contains nine shrubs with 35 stems greater than one-inch with exit holes. Location 3 contains 12 shrubs with 40 stems greater than one-inch, with exit holes. Location 4 contains six shrubs with eight stems that do not contain exit holes. Location 4 likely does not have exit holes as the shrubs are young, with a majority of stems being under one-inch. Lastly, Location 5 contains four shrubs with 22 stems greater than one-inch, with exit holes.

*The USFWS does not consider elderberry shrubs comprised of stems less than one inch dgl potential habitat for VELB.

PROJECT IMPACTS ON VELB

The USFWS Conservation Guidelines state that no adverse effects to VELB are expected when project activities occur at least 100 feet from elderberry shrubs with stems measuring at least one-inch dgl. The USFWS Conservation Guidelines also state that, in areas where encroachment into the 100-foot buffer is necessary, the encroachment must be approved by the USFWS and a minimum setback of 20 feet from the driplines of the elderberry shrubs must be maintained. Project activities that will encroach into the 20- foot minimum setback area may potentially adversely impact VELB.

Within the 100-foot survey area, 32 elderberry shrubs were found, the majority containing indicators of suitable VELB habitat and VELB presence. Approximately 14 elderberry shrubs are within 20 feet of the project footprint (Locations 1, 2, and 3) (Figure 4). However, no shrubs would be directly impacted,

Analytical Environmental Services 8 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Valley Elderberry Longhorn Beetle Effects Analysis removed, or trimmed, as a “no work” buffer would be applied to either side of the proposed project both during and after construction. Elderberry shrubs in Locations 4 and 5 are situated outside of the 20 foot buffer, but are within 100 feet of construction activities and could be indirectly impacted by project activities. Therefore, a potentially significant impact may occur as a result of construction activities.

PROPOSED PROTECTIVE AND MINIMIZATION MEASURES

The following protective measures, consistent with USFWS Conservation Guidelines, will be implemented prior to commencement of construction activities to avoid adverse effects to VELB habitat within 100 feet of the proposed project:

 High visibility construction fencing will be placed around the elderberry shrubs present within the 100-foot study area. The fencing shall extend to the maximum extent feasible, centered on each elderberry shrub to ensure that the active work area is as far away as possible. Avoidance areas are defined as all areas within the fenced buffer surrounding the elderberry bushes. The construction fencing will not be removed until construction activities in the vicinity of the avoidance areas have been completed.  Signs will be erected approximately 50 feet apart along the high visibility construction fencing within the avoidance areas with the following information: “This area is habitat of the valley elderberry longhorn beetle, a threatened species, and must not be disturbed. This species is protected by the FESA of 1973, as amended. Violators are subject to prosecution, fines, and imprisonment.” The signs will be clearly readable from a distance of 20 feet, and must be maintained for the duration of construction.  A qualified biologist will conduct environmental awareness training for all construction personnel regarding the status of the VELB and the need to protect the elderberry host plant. The training will include identification of elderberry shrubs, required practices before the start of construction, general measures that are being implemented to conserve these species as they relate to the proposed project, penalties for noncompliance, and boundaries of the buffer area and permitted disturbance zones. Supporting materials containing training information will be prepared and distributed. Upon completion of training, all construction personnel will sign a form stating that they have attended the training and understand all the conservation measures. Training will be conducted in languages other than English, as appropriate. Proof of this instruction will be kept on file with the contractor. The contractor will provide the USFWS with a copy of the training materials and copies of the signed forms, indicating that training has been completed within 30 days of the first training session. The qualified biologist will request that a representative volunteer train and provide training materials to any new crew members that were not present at the first environmental awareness training.  Staging areas will be located a minimum 30 feet away from all elderberry shrubs. Temporary stockpiling of excavated or imported material will occur only in approved construction staging areas. Excess excavated soil will be used onsite or disposed of at a regional landfill or other appropriate facility.  Standard precautions will be employed by the construction contractor to prevent the accidental release of fuel, oil, lubricant, or other hazardous materials.

Analytical Environmental Services 9 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Valley Elderberry Longhorn Beetle Effects Analysis  A litter control program will be instituted. The contractor will provide closed garbage containers for the disposal of all food-related trash items (e.g., wrappers, cans, bottles, food scraps). All garbage will be removed daily.  Roadways and areas disturbed by project activities within 100 feet of the elderberry shrubs will be watered at least twice per day to minimize dust emissions.  Project-related vehicles will observe a 15 mile-per-hour speed limit within construction areas, except on existing paved roads where they shall adhere to posted speed limits.

Of the 32 elderberry shrubs found within 100 feet of the proposed project, 14 are within 20 feet of the project footprint. The following mitigation measures will be implemented to minimize adverse effects to VELB habitat within 20 feet of the project footprint:

 A qualified biologist will be available for monitoring or consulting during all construction activities occurring within 20 feet of elderberry shrubs.  No work will occur within 20 feet of elderberry bushes from March 15 - June 15 to avoid directly disturbing VELB during their emergence period.  The contractor will ensure that dust control measures (e.g., watering) are implemented in the vicinity of elderberry shrubs. To further minimize adverse effects associated with dust accumulation, elderberry shrubs will be covered by a protective cloth (i.e., burlap or weed mat) during all ground-disturbing activities occurring within 20 feet. The cloth will be removed after ground-disturbing activities are completed. The cloth will extend from the ground upwards a minimum of ten feet along the elderberry shrub.  No insecticides, herbicides, fertilizers, or other chemicals that might harm VELB or the elderberry shrub will be used within the project site.  The contractor will provide a written description of how the construction areas are to be restored, protected, and maintained after construction is completed.  Equipment operators will refrain from working within ten feet of the dripline of elderberry shrubs along Alamo Creek (Locations 2-5) and six feet of the dripline of the single elderberry shrub north of the proposed project (Location 1) to the maximum extent practicable.  Buffer areas will be restored to pre-project habitat conditions immediately upon the completion of construction. No further development of the road or activities within the buffer areas will occur. As the driveway’s limited use is for servicing Well 8, the City will post a “Private Use” sign at the entrance to discourage public trespassing. Additionally, the City will maintain at least one VELB disturbance warning sign described above.

CONCLUSION

The proposed project includes the construction of a new driveway for improved access to Well 8, operated by the City. Limited use of the driveway would occur throughout the year and no activity would be permitted off the driveway, once completed. Construction of the proposed project would maintain a no-work buffer of ten feet from the dripline of all elderberry shrubs along Alamo Creek (Locations 2-5) and a six foot no-work buffer from the dripline of the single elderberry shrub located north of the proposed project (Location 1). Construction would not result in the removal or pruning of any elderberry shrubs. Of the 32 elderberry shrubs found within 100 feet of the proposed project, 14 are within 20 feet of the project

Analytical Environmental Services 10 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Valley Elderberry Longhorn Beetle Effects Analysis footprint. Implementation of the required protective measures identified above would avoid and/or reduce potential adverse impacts to VELB to less than significant levels. With the implementation of the proposed protective, restoration, and maintenance measures identified above, the proposed project may impact, but is not likely to adversely impact VELB.

Analytical Environmental Services i Cultural Resources Summary Report December 2016 1.0 INTRODUCTION

This report presents the scope and results of a cultural resources study for the City of Vacaville Utilities Department Well 8 Driveway Project, located in the City of Vacaville, Solano County, California (Figure 1). All cultural resources work was performed in compliance with the California Environmental Quality Act (CEQA). The proposed project will result in the construction of a new driveway for improved access to Well 8, operated by the City of Vacaville Utilities Department (CVUD).

1.1 PROJECT LOCATION The project is located in the northeast corner of 892 Elmira Road, Assessor’s Parcel Number: 0135030010 (project site), at the intersection of Elmira Road and Leisure Town Road in the City of Vacaville, Solano County, California (Figure 2). The 13.5-acre parcel is bordered by Elmira Road, Leisure Town Road, Patwin Park, and a residential development. Alamo Creek enters the property at the northeast corner, continuing southwest along the center of the parcel. The survey area is in Township 6 North, Range 1 West, Unsectioned Area of Elmira, California U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle.

1.2 PROJECT DESCRIPTION The project includes the construction of a new driveway on Elmira Road, beginning approximately 220 feet west of the intersection with Leisure Town Road (proposed project). An existing driveway currently provides access to Well 8 from Leisure Town Road, adjacent to the project site. However, the California Department of Transportation has approved the Jepson Parkway Project, which includes improvements and expansion of Leisure Town Road, rendering the existing driveway to Well 8 unsafe. As such, the proposed project is needed to provide CVUD with safe vehicular access to Well 8. The new driveway has a centerline length of 197 feet and width of 12 feet. Figure 3 shows the limits of the proposed construction.

2.0 REGULATORY SETTING

Cultural resources include buildings, sites, structures, or objects, which may have historical, architectural, archaeological, cultural, and/or scientific importance. Numerous laws, regulations, and statutes at the federal and State level govern archaeological and historic resources deemed to have scientific, historic, or cultural value. The pertinent regulatory framework, as it applies to the proposed project appears below.

2.1 CALIFORNIA ENVIRONMENTAL QUALITY ACT CEQA requires that, for projects financed by or requiring the discretionary approval of public agencies in California, the effects that a project has on historical and unique archaeological resources be considered (Public Resources Code [PRC] Section 21083.2). Historical resources are defined as buildings, sites, structures, or objects, each of which may have historical, architectural, archaeological, cultural, or scientific importance (PRC Section 50201).

1. The resource is listed in or determined eligible for listing in the California Register of Historical Resources (CRHR). 2. The resource is included in a local register of historic resources, as defined in section 5020.1(k) of the PRC, or is identified as significant in a historical resources survey that meets the requirements of section 5024.1(g) of the PRC (unless the preponderance of evidence demonstrates that the resource is not historically or culturally significant). 3. The lead agency determines that the resource may be a historical resource as defined in PRC section 5020.1(j), 5024.1, or significant as supported by substantial evidence in light of the whole record. Section 5024.1 defines eligibility requirements and states that a resource may be eligible for inclusion in the CRHR if it:

a. Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage; b. Is associated with the lives of persons important in our past; c. Embodies the distinctive characteristics of a type, period, region, or method of construction, represents the work of an important creative individual, or possesses high artistic values; or d. Has yielded, or may be likely to yield, information important in prehistory or history.

Resources must retain integrity to be eligible for listing on the CRHR. Resources that are listed in or eligible for listing in the National Register of Historic Places (NRHP) are considered eligible for listing in the CRHR, and thus are significant historical resources for the purposes of CEQA (PRC section 5024.1(d)(1)).

PRC Section 21083.2 governs the treatment of a unique archaeological resource, which is defined as “an archaeological artifact, object, or site about which it can be clearly demonstrated” that it meets any of the following criteria:

1. It contains information needed to answer important scientific research questions, and there is a demonstrable public interest in that information. 2. It has a special and particular quality such as being the oldest of its type or the best example of its type. 3. It is directly associated with a scientifically recognized important prehistoric or historic event or person.

3.0 NATURAL AND CULTURAL SETTING

3.1 NATURAL SETTING The climate of Solano County is generally characterized as Mediterranean with mild, wet winters, and dry, hot summers. The mean annual precipitation is 14-18 inches per year. Soils on the project site consist of Yolo loam (0 to 4 percent slopes). Yolo loam can be prime

Analytical Environmental Services 5 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Cultural Resources Summary Report farmland if irrigated and develops in alluvial fans (NRCS, 2016). Biotic communities identified on the site include annual grassland and riparian vegetation along Alamo Creek.

3.2 CULTURAL SETTING

3.2.1 ARCHAEOLOGICAL OVERVIEW The project site lies geographically within the Central Valley. Archeological research over the past 70 years has defined the following chronological periods: Paleo-Indian (13,500 to 10,550 B.P.), Lower Archaic (10,550 to 7550 B.P.), Middle Archaic (7550 to 2550 B.P.), Upper Archaic (2550 to 900 B.P.) and Emergent (900 to ca. 200 B.P.). However, there is little evidence of occupation in the Central Valley until the Middle Archaic period (Moratto, 1984).

Generally, the Middle Archaic (7550 to 2550 B.P.) period is seen as a shift from the highly mobile Paleo-Indian and Lower Archaic peoples to a semi-sedentary pattern. Grinding tools, including mortars and pestles, become common in the Middle Archaic and reflect a greater reliance on acorn and other nuts and seeds. Fish and other aquatic resources become a large part of the diet as seen through the variety of new technologies devised for fishing, such as hooks and spears, and a plethora of fish remains. Various new artifact types are introduced in the Middle Archaic such as basketry awls, baked clay objects, and cordage. Artifacts used for personal adornment, such as plummet stones, bird bone tubes, and shell beads become common in Middle Archaic assemblages (Moratto, 1984).

The Upper Archaic (2550 to 900 B.P.) is better understood than any of the preceding periods. Technology becomes specialized during this period, resulting in innovations within bone tools, shell beads, charmstones, and ceremonial blades. The abundance of grinding tools and archaeobotanical remains indicates a heavy dependence upon acorns (Moratto, 1984).

The Emergent Period (900 B.P. to ca. 200 B.P.) in the Central Valley was also a period of technological adaption. A number of cultural innovations shaped the Emergent Period, including replacement of dart and atlatl technology by the bow and arrow. Burial-associated artifacts become more elaborate, suggesting an increase in social stratification and complexity. Subsistence during this period is based on plant foods and aquatic resources (Moratto, 1984).

3.2.2 ETHNOGRAPHIC SETTING Prehistorically, the vicinity of the project site was inhabited by the Patwin Indians. Patwin are members of the California Penutian linguistic stock and are the southernmost division of the Wintuan group, a distinction based primarily on linguistic variation. The core Patwin territory included lands in the southern Sacramento Valley, west of the Sacramento River from the town of Princeton, north of Colusa, and south to San Pablo and Suisun bays (Johnson, 1978).

The Patwin made full use of the various environments within their territory, emphasizing different areas depending on the season and availability of resources. Game was hunted either by the individual or in community drives. Salmon runs and other resources available along the Sacramento River also contributed significantly to Patwin subsistence. Acorns represented one

Analytical Environmental Services 6 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Cultural Resources Summary Report of the most important food resources. Some Patwin communities claimed possession of specific resource gathering areas such as valuable fishing holes and oak groves (Johnson, 1978).

3.2.3 HISTORIC SETTING Following the settlement of San Diego in 1769, the Spanish made steady progress in the exploration and settlement of the coastal regions of Alta (Northern) California. By 1776, the Spaniards established the Presidio of San Francisco and by 1798 Mission San Jose. However, the Central Valley would remain largely uncharted in the first decades of Spanish settlement, until the early 19th Century (Beck and Haase, 1974).

In 1821, Mexican forces prevailed in their struggle for independence and declared California part of the Mexican empire. This event marked the beginning of the short-lived Mexican Period in California history. In 1833, the formal process of secularizing the missions began and mission lands were divided among the Californios. The grants, known as ranchos, enriched those individuals fortunate enough to receive one, while effectively subjugating the native tribes as an indentured labor force.

The proposed project site is located within the Mexican land grant known as Rancho Los Putos, which was granted to Juan Manuel Vaca and Juan Felipe Pena in 1842 by Governor Micheltorena. However, the description of grant’s boundaries was vague and it was soon discovered that the boundaries overlapped a neighboring rancho granted to John Wolfskill. Eventually, the courts ruled in favor of Wolfskill but Vaca, determined to stay in the area, built an adobe structure roughly two miles south of the modern City of Vacaville (Hoover, et al., 2002) (California Historical Landmark #534 – see below).

In 1850, William McDaniel purchased nine square miles of land within the Rancho Los Putos from Manuel Vaca for the sum of $3,000, and proceeded to build a town. The town was recorded as Vacaville in December of 1851 and was incorporated in 1892. The first Euro- American settlers to live in Vacaville, besides McDaniel, toiled on the land cutting wild oats for transport to the Sacramento River (Hoover, et al., 2002). Over time, the agricultural industry in Vacaville grew into a successful business.

4.0 METHODS AND RESULTS

4.1 RECORDS AND LITERATURE SEARCH Analytical Environmental Services (AES) archaeologist Charlane Gross, M.A., RPA completed a record search (NWIC File No. 16-0878) at the Northwest Information Center (NWIC) on December 9, 2016 (Appendix A) as well as reviewed pertinent historical topographic maps and surveyor’s plats. The NWIC is the official repository for archaeological and historical records for the County.

Analytical Environmental Services 7 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Cultural Resources Summary Report Included in the records search review were the California Inventory of Historical Resources and the Historic Properties Directory for Solano County. The Historic Properties Directory includes the CRHR, the most recent listings of the California Historical Landmarks and California Points of Historical Interest, and formal Determinations of Eligibility for the NRHP. The closest California Historical Landmark is the Vaca-Peña Adobe (No. 534), located approximately 4.5 miles to the west of the project site. Located within part of the Rancho Los Putos land grant, the Vaca-Peña Adobe was erected in 1843 and is still owned by descendants of Juan Manuel Vaca and Juan Felipe Pena.

The NWIC records search revealed one previously recorded cultural resource within a ¼-mile radius of the proposed project. That site is P-48-745, a 1920 residence and outbuildings located east of the project site, just across Leisure Town Road. The site was part of the James C. Wells farm, purchased in 1867. It was reviewed (Appendix A) and recommended as not eligible for listing on the CRHR. The NWIC search also determined that only one previous archaeological survey included the project site, although four others included lands within ¼- mile (Table 1).

The General Land Office Plat map for 1859 did not show any development of the project site (BLM, 2016), nor does the Thomas Brothers 1946 map (Appendix A). An online review of historic quadrangle maps shows a structure at the northeastern corner of the proposed project site on the 1917 Elmira 7.5’ USGS quadrangle; that structure is gone by 1946, and there are no historic quadrangles available for the intervening period (USGS, 2016).

4.2 NATIVE AMERICAN CONSULTATION On November 11, 2016, AES sent a letter to the Native American Heritage Commission (NAHC) requesting a Sacred Lands File search and a list of Native American contacts who may have

Analytical Environmental Services 8 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Cultural Resources Summary Report information about the area. In a letter dated November 16, 2016, the NAHC states that the Sacred Lands files indicate the presence of Native American cultural resources in the project region. The NAHC response included contact information for two individuals, Charlie Wright and Leland Kinter. AES sent letters to the two individuals identified by the NAHC on December 2, 2016 and followed up with telephone calls on December 8, 2016. AES left a voicemail for Mr. Wright, but has not received any responses as of this writing (Appendix B). AES spoke with Mr. Laverne Bill, of Yocha Dehe Wintun Nation, who stated that Yocha Dehe Wintun Nation would review the project and respond formally at a future date; no such response has been received as of this writing.

4.3 FIELD METHODS AND RESULTS AES archaeologist Charlane Gross, M.A., RPA completed a survey of the project site on December 9, 2016. The survey area included approximately 50 feet on either side of the proposed driveway in the northeast portion of the parcel bordered by Alamo Creek, Leisure Town Road, and Elmira Road. The entire area was inspected using parallel pedestrian transects spaced at ten meter intervals or less. Thick spring grasses obscured the ground surface, leaving less than one percent ground surface visibility. Along the parcel edges bordering Leisure Town Road and Elmira Road, ground visibility was clear as weed control left a strip up to three feet wide almost entirely bare of vegetation. In areas of less dense vegetative cover, boot scrapes were utilized to further expose the ground surface. No cultural resources were observed.

4.4 DISCUSSION AND RECOMMENDATIONS Cultural resources records search did not reveal any previously identified cultural resources, although a 1917 quadrangle map depicted a structure in the northeastern corner of the project site. Well 8 and/or the parking area may cap any remains from the prior structure. No archaeological resources were discovered during the field survey, and none have been identified by the NAHC. Therefore, AES recommends a finding of No Historical Resources Impacted.

The presence of Alamo Creek on the southern border of the site does increase the potential for as-yet undiscovered buried archaeological sites that could be uncovered during project construction. Should unusual amounts of stone, bone, shell, burned soils, foundations, or other indicators of occupation be found, all work within 50 feet of the find should halt until a qualified professional archaeologist can assess the significance of the resource and make recommendations for evaluation or treatment.

4.4.1 STATEMENT OF CONFIDENTIALITY As nonrenewable resources, archaeological sites can be significantly impacted by disturbances that can affect their cultural, scientific, and artistic values. Disclosure of site information to the public may be in violation of both federal and state laws. To discourage damage resulting from vandalism and artifact looting, cultural resources locations should be kept confidential and report distribution restricted. Applicable laws include, but are not be limited to, Section 304 of

Analytical Environmental Services 9 City of Vacaville Utilities Department Well 8 Driveway Project December 2016 Cultural Resources Summary Report the National Historic Preservation Act (16 USC 470w-3) and the Archeological Resources Protection Act of 1979, as amended (PL 96-95; 93 Stat. 721; 16 USC 47Oaa et seq.). California state laws that apply include, but are not be limited to, Government Code Sections 6250 et seq. and 6254 et seq.

Project Characteristics - Land Use - Construction Phase - The project will most likely be broken down into the following phases: 1. Mobilization & Elderberry Bush Mitigation (fencing, training, etc.) – 2 days 2. Surveying and Grading – 5 days 3. Concrete Driveway – 3 days 4. Asphalt paving – 5 days Off-road Equipment - Equipment required for the work would consist of skid steer loaders, compactors, saw cutters and hand tools. Grading - Approximatley 2,000 sq. ft. of surface area will be excavated for the proposed driveway. Trips and VMT - Approximately 70 cubic yards of soil will be exported from the site. The contractor will likely use a dump truck with a capacity of 12 cubic yards, resulting in 6 trips from the site to export the excess soil. The contractor could potentially be allowed to dump the soil at the Easterly Wastewater Treatment Plant (EWWTP). The trucks would have to drive approximately 3 miles to reach the dump site. On-road Fugitive Dust - Due to the size of the project site, on-site vehicle speed is not expected to exceed more than 15 mph. Water And Wastewater - Land Use Change - Sequestration - e trees consist of two small Yew Pines (Podocarpus Mac.) that were planted with the original landscaping in 1999, and one large Almond tree (19-in diameter dbh).
