Project Number SEA 18-4999.1 ii INTRODUCTION
Stokes Environmental Associates, Ltd. was authorized by Mr. Christopher A. Taylor, PE, Env Sp of Johnson, Mirmiran, & Thompson, to prepare a National Environmental Policy Act (NEPA) Review in compliance with the requirements of the Clean Water Revolving Loan Fund Program, in accordance with the requirements of the NEPA.
Objectives
The National Environmental Policy Act (NEPA) is the basic national charter for protection of the environment. Section 102(2) of NEPA requires federal agencies to act in accordance with the letter and spirit of the Act. Regulations promulgated by the Council on Environmental Quality, (40 CFR 1500) outline methods for evaluating compliance with the Act.
Virginia Code sections 10.1-118 et seq. implement the applicable requirements of NEPA, for major state projects, and requires environmental investigation prior to constructing major projects. The Virginia Clean Water Revolving Loan Fund Program Design Manual provides details of the environmental investigation needed for projects receiving loan assistance under the program, in compliance with NEPA.
The purpose of the following investigation is to provide the investigation required by the Clean Water Revolving Loan Fund program in compliance with the requirements of NEPA.
Period of Investigation and Key Investigators
Investigation of the site was performed during the period of 24 April 2018 through 20 July 2018 as Stokes Environmental Associates, Ltd. (SEA, Ltd.), Project SEA 18-4999.1.
The following Environmental Professionals performed this investigation:
Mr. T. Lane Stokes, III was the Project Manager for this National Environmental Policy Act (NEPA) Environmental Investigation.
Mr. Thomas L. Stokes, Jr. assisted in research and analysis, and provided technical review of this report.
Project Number SEA 18-4999.1 1 FINDINGS OF THE ENVIRONMENTAL INVESTIGATION
Project Description
The City of Norfolk new sanitary sewer pump station is proposed for funding by the Clean Water Revolving Loan Fund Program, to provide needed capacity in the service area in western Colonial Place in Norfolk, Virginia.
The proposed site is located near the intersection of Llewellyn and 38th Street (see attached drawing). The pump station is to be constructed in the center of the northern half of a 0.3 acre, rectangular parcel of land owned by the City of Norfolk, consisting of a grass field surrounded by trees, just south of a stormwater pond. It is to include a raised platform at approximately 18 ft by 44 ft, with a 14 ft by 14 ft submersible pump house to be approximately 11 ft high and 6 ft deep into ground, and will include subsurface piping, reservoirs, and electric/utility connections. The landscaping is to be carried out by Norfolk Recreation, Parks, and Open Space (REPOS) staff, including planning and labor.
Alternative Sites
In order to meet the need for sanitary sewer capacity, minimal environmental impact, and optimal project feasibility, an analysis was conducted by Christopher A. Taylor, P. E., senior associate of Johnson, Mirmiran & Thompson, Inc., which identified all potentially favorable alternative design options that would not result in displacement of private property or loss of essential public services. Further details on alternative site locations are included in the Appendix section of the report. The alternative sites included the following:
Alternative A - Pump Station at Llewellyn Avenue & 38th Street (Proposed Site): This site is located within a grass field between Llewellyn Avenue and the building of former J. E. B. Elementary School (currently inactive). This option would occupy a small amount of space within the floodplain and negligible environmental impacts as described in this report.
Alternative B - No Action: This option is a baseline which has no increased environmental impact. Compared to the other options, no land resources would be used. However, this alternative does not supply the needed capacity, which may have adverse effects on human health and the environment.
Alternative C - Pump Station at Delaware Avenue and Llewellyn Avenue: This site is located in Colonial Place Greenway between a playground and Llewellyn Avenue. The environmental impacts of this option and their degree would be similar to the proposed option at Pump Station at Llewellyn Avenue and 38th Street. The site is within undeveloped floodplain area and would include some blocked view of open space, while the final landscaped pump station would improve the aesthetic quality of the open space area. The City of Norfolk mentioned concern regarding proximity of wetlands. The cost of this option is substantially higher, because this would require 1,160 feet of force main length (more than 7 times longer than the proposed site). The additional underground piping is undesirable for environmental reasons as well as the
Project Number SEA 18-4999.1 2 incremental risk per increased linear foot of pipe. This alternative was not recommended based on cost and environmental concerns.
Alternative D - Pump Station at the terminus of Maryland Avenue: This site is located on southeast corner of Virginia Avenue and Maryland Avenue. The site is within undeveloped floodplain area. The pump station would need to be exceedingly high in order to meet flood elevations, which would have substantial blocked view of open space and minor adverse unavoidable aesthetic impact on Colonial Place Greenway and residences. The City of Norfolk also expressed concern regarding the proximity to wetlands. Therefore this alternative was not recommended.
Alternative E - Pump Station in Colonial Place Circle: This location is within a heavily landscaped traffic circle at the intersection of Delaware Avenue and Colonial Avenue. This option would include substantial blocked view of open space, unmitigatable adverse aesthetic impact, and damage to the critical root zone of old-growth canopy trees. This area is central to the view from heavily trafficked public rights-of-way. This option does not use undeveloped floodplain resources. (The absence of floodplain with this option does not affect flood risk of damage, because the pump station would be built with sensitive equipment at least 3 feet above the 100 year flood elevation just as the other alternate locations. The proposed alternate location is not located in a floodway or a wave action velocity hazard area.) Strong citizen opposition was expressed for this alternative. Also, the required force main length is 2,100 feet, and the force main would need to be located 15 feet below existing grade, rendering this option technically and economically infeasible. Therefore, this alternative was not recommended.
Environmental Assessment
The following is to summarize the finding of the environmental investigation for each alternative.
(1) Effects, destruction and/or displacement of wildlife and marine life, including endangered species, and their habitats, or food chain
The investigation included analysis of biota that might be affected by the alternatives. The Endangered Species Act of 1973 designates the U.S. Department of the Interior (USDI), Fish and Wildlife Service (FWS), as the lead agency with responsibility for protection of threatened and endangered species. Protected species and habitats are specified at 50 CFR 17 222.23(a), 226, and 227.4. Additionally, a search was performed of databases from the Virginia Department of Conservation and Recreation (DCR), the Virginia Department of Game and Inland Fisheries (DGIF), and the Virginia Department of Agriculture and Consumer Services (DACS), with regard to threatened and endangered plants and insects.
Stokes Environmental Associates, Ltd. accessed information directly by online services from the DCR Natural Heritage Resources System (NHRS) database on 27 June 2018 and obtained current information from the database. No federal endangered or threatened species, bald eagle
Project Number SEA 18-4999.1 3 nests or concentration areas, species of concern, or the critical habitats of such species were listed for the site in the US Fish and Wildlife Service Information Planning and Consultation database. Based on the search results, the following federal and/or state listed species are located within a 3-mile radius of the subject site: Turtle, Kemp's ridley sea Lepidochelys kempii; Sturgeon, Atlantic Acipenser oxyrinchus; Turtle, leatherback sea Dermochelys coriacea; Turtle, hawksbill sea Eretmochelys imbricata; Tern, roseate Sterna dougallii dougallii; Turtle, loggerhead sea Caretta caretta; Knot, red Calidris canutus rufa; Bat, northern long-eared Myotis septentrionalis; Turtle, green sea Chelonia mydas; Plover, piping Charadrius melodus; Turtle, eastern chicken Deirochelys reticularia reticularia; Plover, Wilson's Charadrius wilsonia; Rail, black Laterallus jamaicensis; Bat, Rafinesque's eastern big-eared Corynorhinus rafinesquii macrotis; Bat, tri-colored Perimyotis subflavus; Rattlesnake, canebrake Crotalus horridus; Falcon, peregrine Falco peregrinus; Shrike, loggerhead Lanius ludovicianus; Tern, gull-billed Sterna nilotica; Treefrog, barking Hyla gratiosa; Shrike, migrant loggerhead Lanius ludovicianus migrans.
Habitat requirements for each of the above species were evaluated and compared with habitats at the subject site and its immediate vicinity. The recommended project area consists of turf grass and newly planted pine trees (2 inch diameter), and does not currently provide habitat for any species listed in the databases. The pump station construction, maintenance, and operation are not likely to affect surrounding habitat areas for the species. This will result in a de minimis disturbance to potential habitat area, and is unlikely to result in any incidental take of threatened or endangered species.
A Self-Certification Letter documenting compliance with the Endangered Species Act was sent to the U. S. Fish and Wildlife Service on 27 June 2018. No further review is necessary. Official determinations with regard to state listed species can be obtained by requesting review by the DGIF and the DCR if desired. No impact is anticipated.
Based on the results of this preliminary investigation, there appear to be no federal or state listed endangered or threatened species or proposed federal or state listed species or critical habitats at the subject site and no critical habitats near the subject site. No impact is anticipated for alternatives or for the proposed site.
(2) Destruction or disturbance of marshland or wetlands
The National Wetlands Inventory Map from the US Fish and Wildlife Service Web GIS Publication, updated 1 October 2017, does not show designated wetlands on the subject site (see NWI map in Appendix A).
During the site reconnaissance the project area and alternatives appeared to be well drained.
According to the Soil Survey of Norfolk, soils at this site are classified as Augusta-Urban land series. These soils generally consist of silty clay loam. This soil series represents fill soil placed
Project Number SEA 18-4999.1 4 by human activities. Available surveys for the region have not rated this series for general characteristics due to variability depending on recent history of development.
The subject site was evaluated for the presence of jurisdictional wetlands in accordance with the onsite determination methods specified in the U.S. Army Corps of Engineers (COE), Wetlands Delineation Manual (Technical Report Y-87-1) (1987), including interpretations specified by the U.S. Army Corps of Engineers (Memorandum from Major General Arthur E. Williams, Directorate of Civil Works, March 1992).
Wetlands were not found at the subject site, but were located 25 feet north of the pump station platform as part of the vegetated stormwater pond bench, based on preliminary visual inspection. It should be noted that only the U.S. Army Corps of Engineers and Natural Resources Conservation Service (formerly Soil Conservation Service) can make the final official jurisdictional determination for nonagricultural and agricultural areas, respectively.
One minor impact to the wetland north of the site includes potential removal of an existing stormwater discharge pipe to the stormwater pond from the wetland bench area, if the pipe is not abandoned in place. This will result in a de minimis disturbance, initially, and will be a small enhancement the wetland area in the long term.
The proposed project has no permanent direct effect on wetlands and no indirect effect on surface water flow on nearby wetlands.
The no action alternative would cause the low sanitary sewer capacity to continue, which is not protective of wetlands.
(3) Displacement of households, businesses, or services
There are no residents, households, businesses or other activities at the recommended site. The project is located on City owned lands between area zoned as OSP Open Space and Preservation and area zoned as Institutional (IN). The pump station land is located in an original right-of-way designated area. Surrounding areas include parks, stormwater pond with wetland bench, nursing home, residences, and an inactive school. The sanitary sewer pump station has been placed on the north side of the site in order to be the most compatible for the land uses and values of the vicinity. The pump station will not result in any displacement and is not anticipated to have any significant adverse environmental effects that would result in displacement of surrounding residents.
No impact is anticipated for the recommended site.
(4) Possible destruction of surrounding farm land or the loss of open space land
Farmland is a productive use of natural land valued as a resource outside of metropolitan communities. The natural land values are often inadequately addressed by independent market forces, thus federal, state, and local government programs generally consider the potential of a
Project Number SEA 18-4999.1 5 project to result in conversion of important farmland to non-farm use, in order to coordinate the protection of these values. According to the Natural Resources Conservation Service (NRCS) Soil Survey of Norfolk, soils onsite, which consist of fill material, are classified as "not prime farmland" and have not been identified as unique farmland or land of statewide or local importance. The existing site is not valuable as farmland resource. Also, the site is within an urbanized area, so the value of other qualities of the land may likely outweigh the value of farmland productiveness. No impact is anticipated for either alternative.
Open space is valuable for its scenic quality and increase of quality of life of citizens in the locality. The proposed site is located within Colonial Place Greenway, an open space area, and will include a minor degree of blocked view. The proposed site has the least impact on the scenic values of open space of all practicable alternatives identified for the service area, with the Colonial Place Circle (Alternative E) being of greatest concern regarding open space because of impacts to large trees and plantings, and Alternative E was considered infeasible on this basis (among others). All available areas are used as open space. At the proposed location the pump station is situated close to the stormwater pond and away from the intersection to minimize blocking view of scenic open space view from public right-of-way. The project will include addition of 2 large canopy trees, 4 small canopy trees, and 6 small shrubs within the 100 foot Chesapeake Bay Preservation Area buffer. The plan will also include one-to-one replacement or transplant of several sapling trees which will need to be moved in the project, and all compaction and excavation will be located outside of the critical root zone of mature trees so as to avoid adverse impact. The proposed plan includes both a minor adverse impact from effects of blocked view in open space, and a minor beneficial impact of overall increased scenic quality of the open space. The proposed site appears to cause the least impact on open space, in comparison with the alternatives and thus is recommended.
(5) Effects on land having archeological significance
Lands having archeological significance are under the authority of the Department of Historic Resources (DHR) Division of Natural Heritage. Prior to the 1950s the area consisted of undeveloped forested wetlands. In the 1950s during the construction of Llewellyn Avenue, the area was cleared and filled to create the current grass lot. No known historic resources which may have potential archeological significance are located within the direct area of potential effect. Clearance from the State Historic Preservation Officer (SHPO) in regard archeological resources was received and is attached. This is further discussed in the section on Destruction or disturbance of areas of historical significance.
(6) Destruction or disturbance of areas of historical significance
The National Historic Preservation Act of 1966 authorizes the Secretary of the Interior to manage a National Register of districts, sites, buildings, structures, and objects significant in American history, architecture, archeology, engineering, and culture. This National Register of Historic Places (NRHP) is in the custody of the State Historic Preservation Office (SHPO), as approved by the U.S. Department of the Interior (USDI), National Park Service (NPS).
Project Number SEA 18-4999.1 6 Protection of Historic and Cultural Properties by the Advisory Council on Historic Preservation is outlined in 36 CFR 800 including procedures for implementation of the NEPA.
A Direct Area of Potential Effect (Direct APE) was defined including the city-owned property parcel on which the pump station will be built. An indirect Area of Potential Effect (Indirect APE) was defined for the site including: all public right-of-ways within visibility of the pump station and all blocks that include properties from which the sanitary sewer pump station is visible, including visibility from highrise buildings.
Stokes Environmental Associates, Ltd. obtained an archives search from the Department of Historic Resources (DHR) Division of Natural Heritage on 20 June 2018 and obtained current information from the database (Attachment 6). The DHR maintains listings and related maps showing known historic sites and sites which are listed or eligible for listing in the NRHP. The area of potential effect (APE) was reviewed on these maps. The historic resources described below were located within the indirect area of potential effect and no historic resources were located in the direct area of potential effect of the project. .

A response from the request for environmental review for this project by the SHPO was received on July 20, 2018. The SHPO indicated the proposed project will not affect historic resources.
(7) Use of irretrievable resources
Environmental resources used by the project include: developable land (very limited because of zoning, location, size, etc.), open space (again very limited based on small size), Chesapeake Bay Preservation Area buffers (offset by BMP), and floodplains (fully discussed elsewhere in report). The pump station will occupy approximately 800 square feet of land on parcel upon which it is built. Associated landscaping and subsurface vaults and piping will occupy approximately 0.1 acre. Additional information about impact on open space is discussed in the appropriate sections
Project Number SEA 18-4999.1 7 throughout this report. The immediate vicinity of the pump station subject to potential odor is used as open space consisting of trees and grass along Llewellyn Avenue, incorporated into Colonial Place Greenway. The area also serves as a buffer and extension for the recreational field formerly used the inactive J. E. B. Stuart School property, which has been zoned as Institutional. Air quality effects in area immediately surrounding the pump station, outside of the footprint of the structure are compatible with the existing land use and no impact is anticipated. Odor, if any, is expected to be limited to the immediate vicinity of the pump station. Impacts are not expected, based on land use at the institutional land adjacent west of the site and on the subject property, separation from neighbors by street, and stormwater BMP. Based on current land use planning, no impact is anticipated. Significant mineral resources are unlikely to be held by the property. Materials at the project area include urban fill material and a small amount of well-rounded gravel just under the turf. No impact on mineral resources is anticipated. The effect from the land use is a negligible adverse impact.
(8) Noise
Noise will be produced during the construction of the pump station, piping, and appurtenances. Other construction work on buried utilities may be scheduled by the City when the subject project activities are taking place, extending cumulative time period of construction noise. Noise associated with the project activities involves vehicular traffic and operation of heavy equipment onsite, as well as vibratory removal of paved surfaces for the installation of buried piping and appurtenances. Sensitive receptors to noise include single family residences, nursing home, and park area. No historic structures are close enough to the project area or structurally situated in a way that they could be adversely affected by vibratory noise. Short-term noise during construction is a temporary and minor adverse impact.
Noise produced by the completed pump station design is de minimis related to electric water pump operation. Road noise reduction by the pump house serving as a sound barrier on the west side of Llewellyn Avenue is a minor beneficial impact.
(9) Traffic circulation and traffic pattern disruption
Construction of the pipes associated with the pump station will involve construction work on th Llewellyn Avenue and 38 Street in and around the intersection. Simultaneous non-project work on water/utilities will be conducted in the same area. Appropriate detour routes and signage will be obtained for the project if needed. This is a minor adverse impact.
Ms. Thelma Drake, Assistant Director of Transportation in the City of Norfolk Division of Transportation, was contacted by telephone on July 2, 2018 and confirmed that no existing roads, transportation plans, or anticipated future plans would be adversely affected by the final constructed pump station. Long term traffic circulation and traffic patterns are not anticipated to be impacted.
Project Number SEA 18-4999.1 8 (10) Odor/air quality
Sanitary sewer pump stations remove any free gas present flowing through the pipes; also, a small amount of sewer gas is released due to fluctuations of sewage levels in the wet well. Odiferous constituents in sewer gas and their odor threshold include the following: Hydrogen Sulfide (0.00047 ppm), Ethyl Mercaptan (0.00019 ppm), Methyl Mercaptan (0.0011 ppm), Dimethyl Sulfide (0.0001 ppm), Sulfur Dioxide (0.009 ppm), Benzyl Mercaptan (0.00019 ppm).
The 2018 Hampton Roads Sanitation District (HRSD) Design and Construction Standards include evaluation of the need for odor control and provision for odor control devices as necessary. There will be some amount of sewer gas emission from the final pump station; however, it is expected to be undetectable most of the time based on experience with other pump stations. The pump station is located approximately 100 feet northeast of playground structures and approximately 150 feet from the nearest housing. A grass path and sidewalk (next to the roadway) pass approximately 13 and 18 feet of the station. The pump station is located a sufficient distance from the housing and playground structures that odor is not likely to affect these existing sensitive receptors in the surrounding land. No impact is anticipated for sensitive receptors. In the unlikely event of odor impacts, it is anticipated that air scrubbers can be added to eliminate any such odor. The current and anticipated future land use of unoccupied open space use near a roadway is compatible with potential effect on air quality in the immediate vicinity of the pump station, thus no impact is anticipated.
(11) Damage and/or pollution of surface water resulting from erosion, discharges or other sources
Evaluation of the site with respect to surface features included an onsite survey of the property and a review of U.S. Geological Survey (USGS) topographic mapping, U. S. Fish and Wildlife Service (FWS) wetlands mapping, local records for other regulated surface features, and available aerial photographs. According to information reviewed and onsite observations, surface water drainage at the subject site appeared to be generally toward the north then following the lowland just west of the site in the 100 foot Chesapeake Bay Preservation Area buffer, in a northerly direction. It drains into the municipal stormwater system (as opposed to infiltration), which discharges into the Best Management Practice (BMP) pond adjacent to the project area, which discharges into the Lafayette River.
The completed project will include approximately 800 square feet of impervious surface in a Chesapeake Bay Preservation Area, resulting in higher volume of stormwater discharge from the pump station platform footprint. Considering the course of surface water flow, nonpoint sources of pollution, intensely developed area, and other factors, the completed pump station project area is not expected to significantly increase total discharge of pollutants, though the volume of stormwater discharge would increase lightly because of the small addition of impervious surface. The design plan is required to satisfy at least the requirements of the Norfolk Bureau of Environmental Service, which is to compensate for the impervious surface encroachments into the Chesapeake Bay Preservation Area buffer (CBPA). The mitigation plan will include placement of 2 large canopy trees, 4 small canopy trees, and 6 small shrubs within the CBPA, in
Project Number SEA 18-4999.1 9 addition to the replacement or transplant of the existing newly planted trees as discussed elsewhere. This will provide canopy coverage and will increase the absorptiveness of the soil to mitigate floodwater volume, allowing for greater infiltration of runoff containing nonpoint source pollutants. In regard to surface water discharge volume and quality, the impervious surface is expected to be a minor adverse impact and the added vegetation will have a minor beneficial impact.
Runoff pollution from land disturbance contains sediment and pollutants bound in the sediment. During the construction phase of the project, the runoff pollution will be limited by a Virginia Sediment and Erosion Control Plan, which is to be included in the project. The short-term runoff pollution during construction will be a de minimis adverse impact, and all alternatives had similar effect.
(12) Aesthetic concerns and visual impacts
The pump station will have a minor affect on view, including view of open space. See the Appendix section of this report for the map of Area of Indirect Affect, which depicts properties from which the pump station will be visible, including visibility from a high-rise building, Colonial Place Greenway a nursing home, single-family homes, City property containing the th inactive school site, Llewellyn Avenue, 38 Street, and walkways. The aesthetic/visual effect includes a de minimis adverse effect related to the use of a small amount of open space. A minor beneficial effect on the scenic values of open space is expected because of the installation of trees and landscaping. The visual impact was considered to be higher at alternative E and is equivalent at all other alternatives, including the proposed alternative.
(13) Any disturbance to designated wild, scenic and/or recreational river use
The subject site is located within one mile of the Lafayette River. The Lafayette River is neither a designated Wild & Scenic River, nor a river being studied as a potential component of the Wild & Scenic River system, nor a river listed in the National Rivers Inventory. The site is not located on or visible from any rivers. No impact is anticipated.
(14) Socio-economic changes
Effects on socio-economic prosperity of the City of Norfolk and human environment for communities with City of Norfolk, include aesthetics (a de minimis adverse impact and minor beneficial impact), use of land resources, and requires land uses at the adjacent institutional land and on Colonial Place Greenway on the subject property to be compatible (no impact or minor adverse impact). Improved sanitary sewer capacity is an obvious benefit of the pump station. No overall significant impact is anticipated with regard to employment or adverse effect on surrounding residents.
Project Number SEA 18-4999.1 10 The area of effect of the pump station does include a percentage of socio-economically vulnerable people. The percentage of minorities and low-income people in the area of effect of the project is slightly greater than the state average. All neighborhoods need pump station capacity, and most have pump stations. There is not a disproportionate impact on any socio- economic group.
No impact is anticipated, except improved sanitation in the Colonial Place Neighborhood is a beneficial impact.
(15) Floodplain impacts
Executive Order 11988 - Floodplain Management, dated 24 May 1977, requires agencies to determine whether any proposed action will occur in a floodplain, and stipulates procedures to be followed for any action to be located within a floodplain. The term “floodplain” is defined in the Executive Order to mean the lowland and relatively flat area adjoining inland and coastal waters including flood-prone areas of offshore islands, including at a minimum, that area subject to a one percent (1%) or greater chance of flooding in any given year. The Federal Emergency Management Agency (FEMA) Flood Insurance Manual, dated 1985, indicates that the floodplain described in the Executive Order is, by definition, the 100-year floodplain. FEMA regulations for Floodplain Management and Flood Hazard Identification (44 CFR 59 through 77) provide further clarification and was relied on in this investigation.
Flood Insurance Rate Maps and Flood Hazard Boundary Maps, as prepared by FEMA, provide the usual and customary basis for determining whether a site occurs within a 100-year floodplain. According to information found in Flood Hazard Boundary Map and Flood Insurance Rate Map 5101040018H dated 17 February 2017 for Norfolk, Virginia, reviewed by Mr. Lane Stokes, the property is located in zone AE. Zone AE signifies areas within the 100- year flood plain where Base Flood Elevations have been determined. The property is not located in a floodway or a wave action velocity hazard area. Regardless of the ground surface elevation, the pump station will be built with a Design Flood Elevation three feet above the Base Flood Elevation for the 100 year flood event, which at this location is 8 feet above mean sea level resulting in a floor elevation of 11 feet above mean sea level. The control platform and all water sensitive equipment will be built above the Design Flood Elevation to the extent feasible. This Design Flood Elevation is also required by City of Norfolk standards. No impact by damage to the pump station is anticipated from flooding.
Sensitive geomorphic features such as flood plains, topography, drainage routes, surface water (i.e., streams, creeks, lakes, or rivers), infiltration and groundwater features, wetlands, and forests are of potential importance to the human environment due to the functions and values of such features. The functions and values include natural habitat, enhancement to water quality, scenic open space value of adjacent water bodies, and a migration corridor for wetlands and stream buffers to ensure their future presence following sea level rise. The subject property was visually and physically evaluated for the presence of sensitive and geomorphic features in order to determine whether the project would present any potential for significant change in such features.
Project Number SEA 18-4999.1 11
According to a survey and engineering plan drawing provided by Johnson, Mirmiran and Thompson, dated June 2018 the property and proposed construction area is located within the 100 foot Chesapeake Bay Preservation Area buffer and is regulated under the Norfolk Chesapeake Bay Preservation Ordinance. According to the Natural Resources Conservation Service (NRCS), Virginia Hydrologic Unit Atlas (1995), the site is within the Elizabeth River (JL56) Unit of the Hampton Roads Drainage Basin. Construction of the proposed facility will include placement of clean fill soil on a 50 foot by 100 foot area of grass to be reseeded, graded to slope gradually from the existing ground surface at the edge of the fill area to 4.5 feet above ground surface at the base of the elevated pump station platform. This is a substantial change to topography, increasing the area of lost floodplain beyond the footprint of the building. This is a minor adverse impact based on small size. Notwithstanding this minor adverse impact, the proposed location has less overall environmental impact than the alternative locations, and the otherwise compatibility of the land uses may work to preserve this area that may otherwise be lost from competing land uses such as future development of the area in the future. Assessment on existing environmental values is discussed in the respective sections throughout this report. Due to loss of floodplain area needed for the pump station and due to re-contouring within the floodplain, there is a minor adverse impact. This impact is offset by installation of landscape plantings, but the physical footprint is the minimum needed for pump station operations. The enhanced pumping capacity reduces potential for bypass upsets, which reduce the risk of impacts to waterways; thus, the proposed site is considered to provide an overall benefit to floodplain areas. All alternative sites, except Colonial Place Circle (Alternative E) which is outside the floodplain, had similar conclusions regarding floodplains.
Project Number SEA 18-4999.1 12 SUMMARY AND CONCLUSION
This National Environmental Policy Act (NEPA) Environmental Investigation has reviewed a sanitary sewer pump station, including alternative sites, with respect to environmental effects, based on items described in the Virginia Clean Water Revolving Loan Fund Program requirements.
Four alternatives were reviewed including a no-action alternative (continued operation of existing pump station and three alternative sites).
Short-term and long-term effects were considered. The analysis included each of the following areas of concern:
(1) Effects, destruction and/or displacement of wildlife and marine life, including endangered species, and their habitats, or food chain (2) Destruction or disturbance of marshland or wetlands (3) Displacement of households, businesses, or services (4) Possible destruction of surrounding farm land or the loss of open space land (5) Effects on land having archeological significance (6) Destruction or disturbance of areas of historical significance (7) Use of irretrievable resources (8) Noise (9) Traffic circulation and traffic pattern disruption (10) Odor/air quality (11) Damage and/or pollution of surface water resulting from erosion, discharges or other sources (12) Aesthetic concerns and visual impacts (13) Any disturbance to designated wild, scenic and/or recreational river use (14) Socio-economic changes (15) Floodplain impacts
Based on this analysis, the proposed project was found to have no significant adverse environmental impact.

Taylor of Johnson, Mirmiran, & Thompson (Client) in the preliminary assessment of environmental conditions at the subject property, as outlined in this report. This report has been prepared solely for the exclusive use of Client and its agents for specific application to the property assessed. No other person or business entity shall have any rights with regard to our contract for this project, or any rights of reliance on this report or related documents prepared by Stokes Environmental. The scope of services included in this study may not be appropriate to the needs of other users of this document, and any such use is at the risk of user. This investigation was conducted in accordance with the scope of work, terms, and conditions outlined in the applicable contract or letter of agreement between Client and Stokes Environmental Associates, Ltd. In the event of any conflict between this disclaimer and the applicable contract or letter of agreement, the contract or letter of agreement shall take precedence.
This work has been performed using reasonable care within the scope of work and in accordance with budgetary limitations. Stokes Environmental Associates strives to conduct its services in keeping with industry standards and in accordance with generally accepted environmental science practice. No other warranty, expressed or implied, is made.
Our conclusions and recommendations are based upon our observations at the site, the reviewed documentation, any test results reviewed, interviews, any other information provided and our previous experience in this area. The conclusions and recommendations assume that data and other information provided are reasonably accurate. It must be recognized that available agency records, addresses, maps, and other information reviewed in this assessment are often incomplete, contain errors, may not be current, may list alternate facility names or addresses, or may provide otherwise misleading data. Verification of agency data, determination of facility locations that are listed by post office box, continuous updating and other tasks related to database information are generally beyond the scope and cost allowances of this investigation. However, the Environmental Professional performing the review has made a reasonable effort to compensate for mistakes or insufficiencies in the information reviewed that are obvious in light of other information actually known to the Environmental Professional. It should also be recognized that information may be available which was not found or reviewed in this assessment. The conclusions and recommendations are based on a limited review of the site and cannot provide complete assurance that all liabilities were detected. The conclusions and recommendations do not reflect variations in site conditions not visually apparent or which could exist intermediate of the sample locations or which could exist in the future.
Stokes Environmental Associates, Ltd. has analyzed the information obtained in this investigation in keeping with existing guidelines and regulations, but cannot accurately predict what actions or interpretations any given agency may take presently, or what standards and practices may apply to the site in the future. Should such variations in regulations, guidelines or site conditions become apparent in the future, it will be necessary to reevaluate our conclusions and recommendations based upon additional analyses and on-site observations as appropriate. It should be noted that only the appropriate regulatory agencies can make the final decision with respect to the extent of their jurisdiction. This site assessment report is not intended to provide a regulatory compliance audit. Unless known conditions indicate other durations, it is generally assumed that a site assessment is viable for a period of 180 days.
The pricing for this work is based on the absence of personal liability of the preparers with respect to the work, and the understanding that any claim associated with the work shall look solely to Stokes Environmental Associates, Ltd.
Stokes Environmental Associates, Ltd. acknowledges that it maintained in full force and effect at the time the services described in the investigation were performed, professional liability (errors and omissions) insurance with minimum policy limits of one million dollars each occurrence and one million dollars in the aggregate. Stokes Environmental Associates, Ltd. currently maintains such insurance in full force and effect and currently has no plan to terminate such insurance in the foreseeable future. Stokes Environmental Associates, Ltd.'s liability in connection with this investigation shall cease after a period of three years from the date of completion of the study, and Stokes Environmental Associate's total aggregate liability in connection with the investigation shall not exceed that amount actually covered by insurances on any such claim.
Please note that no environmental investigation can wholly eliminate uncertainty regarding the potential for adverse environmental conditions in connection with a property. This study is intended to reduce, but not eliminate, such uncertainty. The investigation recognizes reasonable limits of time and cost, and is designed to provide an appropriate level of inquiry, based on existing industry standards.

Area Size 0.3 SECTION IV. AREA OF POTENTIAL EFFECT (APE) https://solutions.virginia.gov/epix/secure/PrintApplication.aspx?id=6fef56ac-dcd9-4328-953c-3a2fd03981c9 3/5 7/12/2018 ePIX - Print Application The Area of Potential Effects (APE) is defined as the geographic area or areas within which a project may directly or indirectly cause changes in the character or use of historic properties, if they exist. It is not necessary for an historic property to be present in order to define an APE.
An example of a direct effect is the demolition of an historic building while an indirect effect would be the alteration of an historic setting resulting from the construction of a communications tower or the introduction of noise as the result of the construction of factory. An area such as the footprint of a proposed building is obviously within the APE, but you must also consider visual effects on the property and the limits of all ground-disturbing activity. So, any project may have two APEs - one for direct effects and one for indirect effects.
Please see our guidance on Defining Your APE for more detailed information on defining direct and indirect APEs. If you are using DHR's Data Sharing System, you should indicate the APE on the DSS map. For instructions on how to do this, consult the DSS general use guidelines.
Please provide a brief summary of and justification for the APE and upload your APE map at the end of the application. The written boundary description must match the submitted APE map.
Excavation and construction activities will occur on a 0.3 acre area of land. The area of potential effect, shown in the attached documents, encompasses all properties and public right-of-ways from which the sewer pump station is visible, including visiblity from highrise buildings, and all blocks adjacent to blocks that include visibility of the pump station. Indirect effects include the visual character of Llewellyn Avenue and 38th APE Street as routes of travel. SECTION V. CONSULTING PARTIES AND PUBLIC INVOLVEMENT
The views of the public, Indian tribes and other consulting parties (e.g. local governments, local historical societies, affected property owners, etc.) that may have an interest in historic properties that may be affected by the project are essential to informed decision-making. In some cases, the public involvement necessary for other environmental reviews such as that under the National Environmental Policy Act (NEPA) may be sufficient for the Section 106 process, but the manner in which the public is involved must reflect the nature and complexity of the proposed project and its effects on historic resources.
What consulting parties have you identified that have an interest in this project? Please describe your previous and future efforts to involve consulting parties.
Norfolk Historical Society. An email was sent to the consulting party. See Consulting Parties attachments.
