Project Information

a. Project information provided by the Permittee included a JPR Application (revised March 15, 2021), City of Temecula Cover letter (revised March 3, 2021) both prepared by the City of Temecula, and Western Riverside County Multiple Species Habitat Conservation Plan Consistency – Pala Community Park Sheet Pile Wall Construction1 (Analysis), (revised February 9, 2021), collectively prepared by City of Temecula, CWE Corporation, and Psomas. b. Project Location: The project is located in the City of Temecula at the north end of Pala Park. Surrounding land uses consist of residential development to the south and Temecula Creek to the north. c. Project Description: The project proposes installation of a sheet pile wall, approximately 427 feet in length, and an associated anchor system along the northern boundary of the existing soccer field in Pala Park. An impact pile driver will be used to install the sheet pile wall. The sheet pile wall will be driven to a maximum depth of 35 feet below ground surface. Wall anchors will be placed subsurface to hold the sheet pile wall in place in the event that Temecula Creek erodes further and potentially all the way to the sheet pile wall. Any excess materials will be hauled off the site. The sheet piles will be driven into the

ground causing vibration. Based on the subsurface conditions, the upper 20 feet of soil is loose to medium dense and below 20 feet, soil material becomes denser. Dense soils facilitate greater vibration. However, given that these denser soils are at deeper depths, vibration towards ground surface diminishes and vibration level is anticipated to be below the threshold that would cause damage to the surrounding area. Given the distance to the bank, 6-foot height of the bank, and depth to dense soils, the City has stated that significant vibration towards the bank is not anticipated. The proposed project limits of work cover 0.62 acre and include an approximately 0.35-acre area where equipment would be staged, 0.01 acre for the sheet pile, another 0.16 acre of staging area, and 0.10 acre for the access route from the staging area. Soils on site consist of Grangeville fine sandy loam, Hanford course sandy loam, Riverwash, and Tujunga loamy sand. On-site vegetation communities consist of ruderal, ornamental, and disturbed habitat.

Relation to Reserve Assembly a. As stated in Section 3.2.3 of the MSHCP, “Proposed Constrained Linkage 14 consists of portions of Pechanga and Temecula Creeks, located in the southwestern region of the Plan Area. This Constrained Linkage connects Existing Core G (Santa Margarita Ecological Reserve) and Proposed Linkage 10 in the west to Existing Linkage A in the south. This Linkage bifurcates and may be used to move directly to the east, along Temecula Creek, or to the southeast, along Pechanga Creek to Existing Linkage A. This Linkage is constrained along most of its length by existing urban Development and the planned land uses surrounding the Linkage consist almost entirely of city (Temecula). I-15 also intersects the Linkage at its western terminus. Therefore, high quality Live-In riparian Habitat must be maintained, and movement Habitat for bobcat and mountain lion must be provided, as these species are known to use the Linkage for movement. This portion of Pechanga and Temecula Creek may serve as one component of a larger movement corridor for mountain lions traveling between the Santa Ana Mountains and the Palomar Mountains. A Linkage between these two mountain ranges would reduce the risk of extirpation of the Santa Ana Mountains population of mountain lion, which was considered to be “demographically unstable” without a movement connection (Beier 1993). Maintenance of contiguous Habitat with appropriate refugia for resting, such as rockpiles, brush piles, windfalls, hollow snags, and hollow trees, is important for dispersal of juveniles. Maintenance of existing floodplain processes and water quality along the creek is also important for wetland species noted in the table below.” (refer to MSHCP Table XXXX) b. A portion of the project site is located within Cell 7445, independent of a Cell Group. Conservation within this Cell will contribute to assembly of Proposed Constrained Linkage 14. Conservation within this Cell will focus on riparian scrub, woodland, forest and grassland habitat along Temecula Creek. Areas conserved within this Cell will be connected to riparian scrub, woodland and forest habitat proposed for conservation in Cell 7444 to the west and 7446 to the east, and to riparian scrub, woodland, forest, and grassland habitat proposed for conservation in Cell 7358 to the north. Conservation within this Cell will range from 10%-20% of the Cell focusing in the northern portion of the Cell.

A portion of the project site is also located within Cell 7446, independent of a Cell Group. Conservation within this Cell will contribute to assembly of Proposed Constrained Linkage 14. Conservation within this Cell will focus on riparian scrub, woodland, forest and grassland habitat along Temecula Creek. Areas conserved within this Cell will be connected to riparian scrub, woodland, forest, and grassland habitat proposed for conservation in Cell 7359 to the north and in Cell 7445 to the west. Conservation within this Cell will range from 10%-20% of the Cell focusing in the northern portion of the Cell. c. Rough Step: The proposed project is located within Rough Step Unit 5. According the MSHCP 2019 Annual report, Rough Step Unit 5 encompasses 91,734 acres within the southwestern corner of western Riverside County and includes the Santa Rosa Plateau, the Tenaja Corridor, and Murrieta Creek (see Figure 3-6, Rough Step Unit 5). This Unit is bound by Interstate 15 to the east, San Diego County to the south, and the Santa Ana Mountains in the Cleveland National Forest to the west and north. Within Rough Step Unit 5, there are 24,326 acres within the Criteria Area. Key vegetation communities within Rough Step Unit 5 include: coastal sage scrub; grasslands; riparian scrub, woodland, forest; Riversidean alluvial fan sage scrub; and woodlands and forests. Rough Step acreage goals are provided for each of these habitat types. Table 3-11, Rough Step Unit 5 Acreage Totals, also includes acres conserved for habitats for which Rough Step acreage goals do not exist. A total of 1,443 acres of conservation has been acquired within this Rough Step Unit. Losses to this unit total 2,172 acres, with remaining development allowance as followed: 185 acres of coastal sage scrub, 114 acres of grasslands, 8 acres of Riversidean alluvial fan sage scrub, and 198 acres of woodlands and forests. The riparian scrub, woodland, forest vegetation category is out of Rough Step balance by 1 acre. The RCA is actively engaged in acquiring parcels that would bring riparian scrub, woodland, forest back into Rough Step for Unit 5. The total acreage needed is 5.7 acres of riparian scrub, woodland, forest. The proposed project will impact 0.6 acre of grassland, not riparian scrub, woodland, forest vegetation. Therefore, the project does not conflict with Rough Step. ROUGH STEP MEASURE. In accordance with Section 6.7 in Volume I of the Plan, it is the Permittees responsibility that if the rough step rule is not met during any analysis period (performed annually by the RCA), the Permittees must conserve appropriate lands supporting a specified vegetation community within the analysis unit to bring the Plan back into the parameters of the rule prior to authorizing additional loss of the vegetation community for which the rule was not achieved. The Permittee must not cause additional loss of any rough step vegetation that is out of balance. Prior to vegetation removal, the City of Temecula will confirm with the RCA that the project will not impact out-of-balance Rough Step vegetation in the applicable rough step unit. This measure is included here in case the Rough Step vegetation becomes out of step between now and vegetation removal. d. Reserve Assembly Summary: As discussed above, the project site is located in Cell 7446 which contributes to proposed constrained linkage 14. Currently, 15% of the Cell is described for conservation (22.22 acres). To date, approximately 122.14 acres have been developed or are approved for

3 RCA Joint Project Review (JPR) JPR #: 18-08-30-01 Date: 03/23/2021

development in this Cell there are 11.24 acres of PQP lands and 0.04 acre of covered roads; 8.06 acres in this Cell have been conserved. The proposed project acreage within this Cell is 0.28 acre, leaving 6.39 acres of undeveloped lands potentially available for Conservation in this Cell. The project site is also located in Cell 7445 which contributes to proposed constrained linkage 14. Currently, 15% of the Cell is described for conservation (22.76 acres). To date, approximately 110.11 acres have been developed or are approved for development in this Cell (this includes undeveloped land exempt from the MSHCP), there are 4.56 acres of PQP lands and14.84 acres of covered roads; 0 acres in this Cell have been conserved. The proposed project acreage within this Cell is 0.34 acre, leaving 21.88 acres of undeveloped lands potentially available for Conservation in this Cell. All proposed impacts from the project occur in the existing Pala community park, which will remain open space following the project. Furthermore, the project has no impact to Temecula Creek, which is the feature described for conservation in these Cells. Based on the information provided here the project as proposed does not conflict with the Reserve Assembly goals of the MSHCP, nor would it cause issues related to fragmentation for Planning Species such as Cooper’s hawk, downy woodpecker, least Bell’s vireo, loggerhead shrike, southwestern willow flycatcher, tree swallow, white-tailed kite, yellow- breasted chat, yellow warbler, bobcat, Los Angeles pocket mouse, mountain lion, western pond turtle

Comments on Other Plan Requirements:

a. Section 6.1.2. The project site was assessed for Riparian/Riverine features on January 22, 2019. Temecula Creek with associated riparian vegetation is directly to the north of the property site. The limits of work do not extend into Temecula Creek and there will be no impacts to the creek or associated vegetation. There will be temporary noise disturbance, but all noise-generating work will occur outside of the nesting season (March 1- September 15). Vernal Pools/Fairy Shrimp: The project site lacks the appropriate soil and vegetation associated with vernal pools. The proposed project site does not contain evidence of vernal pools or other seasonally inundated depressions, such as cracked, hydric soils, or standing water. Furthermore, no clay soils or heavy soils were mapped, and no ponding or depression areas that could hold water for an extended period of time were detected on the project site. Due to the lack of vernal pools and/or other suitable fairy shrimp habitat, focused surveys for fairy shrimp were not conducted. Riparian Birds: The portion of Temecula Creek that is north of the project site consists of habitat that is suitable for riparian birds. Although the proposed project has no impacts to the creek or associated vegetation; however, a previous version of the project footprint would have resulted in impacts. Therefore, focused surveys were previously conducted April 24; May 9, 22; June 5, 15, 27; and July 11 and 24, 2019. Southwestern willow flycatcher and western yellow-billed cuckoo were not detected during the focused surveys. One male least Bell’s vireo was observed singing during the May 9, 2019 focused survey. This individual was located in the western portion of the survey area, on the north side of Temecula Creek. As mentioned above the proposed project will have no impacts to least Bell’s vireo habitat. In addition, to avoid indirect impacts from noise, the anticipated timeframe for construction is from September 16 through February 28. This timeframe occurs during the dry-weather period and is outside the least Bell’s vireo nesting season (March 1 to September 15). Based on the information provided in the Analysis, the project demonstrates consistency with Section 6.1.2 of the MSHCP. b. Section 6.1.3: The project site is not located within a Narrow Endemic Plant Species Survey Area (NEPSSA). Based on the information provided in the Analysis, the project demonstrates consistency with Section 6.1.3 of the MSHCP. c. Section 6.3.2: The project site is not located in a Criteria Area Species Survey Area (CASSA) for plants. The project site is located in an area requiring an assessment for burrowing owl. The project site, in addition to an associated 150-meter buffer, were subject to an initial burrowing owl habitat assessment (Step I of the Burrowing Owl Survey Instructions, 2006) on January 22, 2019. Suitable habitat is present with upland areas and on the slopes separating the wash from the upland areas. Due to the presence of potentially suitable habitat, a focused burrow survey (Step II-A) was conducted on April 24, 2019. Three potential burrows were observed during the habitat assessment and focused burrow survey. Due to the

5 RCA Joint Project Review (JPR) JPR #: 18-08-30-01 Date: 03/23/2021

presence of potential burrow habitat, Step II-B focused owl surveys were conducted on April 24, May 9, June 27, and July 24, 2019. No burrowing owl or sign was detected during the focused surveys. Burrowing Owl Measure. Due to the presence of potentially suitable habitat, a 30-day pre- construction survey for burrowing owls is required prior to initial ground-disturbing activities (e.g., vegetation clearing, clearing and grubbing, grading, tree removal, site watering, equipment staging) to ensure that no owls have colonized the site in the days or weeks preceding the ground- disturbing activities. If burrowing owls have colonized the project site prior to the initiation of ground-disturbing activities, the project proponent will immediately inform the Regional Conservation Authority (RCA) and the Wildlife Agencies, and will need to coordinate further with RCA and the Wildlife Agencies, including the possibility of preparing a Burrowing Owl Protection and Relocation Plan, prior to initiating ground disturbance. If ground-disturbing activities occur, but the site is left undisturbed for more than 30 days, a pre-construction survey will again be necessary to ensure that burrowing owl have not colonized the site since it was last disturbed. If burrowing owl is found, the same coordination described above will be necessary. Based on the information provided in the Analysis, the project demonstrates consistency with Section 6.3.2 of the MSHCP. d. MSHCP Volume I, Section 6.1.4 MEASURES. To preserve the integrity of areas adjacent to the project site which are proposed Conservation Areas, the guidelines contained in Section 6.1.4 related to controlling adverse effects for development adjacent to the MSHCP Conservation Area should be considered by the Permittee in their actions relative to the project. Specifically, the Permittee should include the following measures as Project conditions of approval when applicable. i. Incorporate measures to control the quantity and quality of runoff from the site entering the MSHCP Conservation Area. In particular, measures shall be put in place to avoid discharge of untreated surface runoff from developed and paved areas into MSHCP Conservation Areas. Regular maintenance will occur to ensure effective operation of runoff control systems. ii. Land uses proposed in proximity to the MSHCP Conservation Area that use chemicals or generate bioproducts, such as manure, that are potentially toxic or may adversely affect wildlife species, Habitat, or water quality shall incorporate measures to ensure that application of such chemicals does not result in discharge to the MSHCP Conservation Area. The greatest risk is from landscaping fertilization overspray and runoff. iii. Night lighting shall be directed away from the MSHCP Conservation Area and the avoided area on site to protect species from direct night lighting. Shielding shall be incorporated in project designs to ensure ambient lighting in the MSHCP Conservation Area is not increased. The project does not include night lighting. iv. Proposed noise-generating land uses affecting the MSHCP Conservation Area, including designated avoidance areas, shall incorporate setbacks, berms, or walls to minimize the effects of noise on

6 RCA Joint Project Review (JPR) JPR #: 18-08-30-01 Date: 03/23/2021

MSHCP Conservation Area resources pursuant to applicable rules, regulations, and guidelines related to land use noise standards. v. Avoid use of invasive, non-native plant species listed in Table 6-2 of the MSHCP in approving landscape plans for the portions of the project that are adjacent to the MSHCP Conservation Area, including avoidance areas. Considerations in reviewing the applicability of this list shall include proximity of planting areas to the MSHCP Conservation Areas and designated avoidance areas, species considered in the planting plans, resources being protected within the MSHCP Conservation Area and their relative sensitivity to invasion, and barriers to plant and seed dispersal, such as walls, topography, and other features. The project does not include landscaping. vi. Proposed land uses adjacent to the MSHCP Conservation Area shall incorporate barriers, where appropriate, in individual project designs to minimize unauthorized public access, domestic animal predation, illegal trespass, or dumping into existing and future MSHCP Conservation Areas. Such barriers may include native landscaping, rocks/boulders, fencing, walls, signage, and/or other appropriate mechanisms. vii. Manufactured slopes associated with proposed site development shall not extend into the MSHCP Conservation Area. viii. Weed abatement and fuel modification activities are not permitted in the Conservation Area, including designated avoidance areas. Based on the information provided in the Analysis, the Project demonstrates consistency with Section 6.1.4 of the MSHCP. e. MSHCP Volume I, Appendix C MEASURES. The following best management practices (BMPs), as applicable, shall be implemented for the duration of construction:

i. A condition shall be placed on grading permits requiring a qualified biologist to conduct a training session for project personnel prior to grading. The training shall include a description of the species of concern and its habitats, the general provisions of the Endangered Species Act (Act) and the MSHCP, the need to adhere to the provisions of the Act and the MSHCP, the penalties associated with violating the provisions of the Act, the general measures that are being implemented to conserve the species of concern as they relate to the project, and the access routes to and project site boundaries within which the project activities must be accomplished. ii. Water pollution and erosion control plans shall be developed and implemented in accordance with RWQCB requirements. iii. The footprint of disturbance shall be minimized to the maximum extent feasible. Access to sites shall be via pre-existing access routes to the greatest extent possible.

7 RCA Joint Project Review (JPR) JPR #: 18-08-30-01 Date: 03/23/2021 iv. The upstream and downstream limits of projects disturbance plus lateral limits of disturbance on either side of the stream shall be clearly defined and marked in the field and reviewed by the biologist prior to initiation of work. v. Projects should be designed to avoid the placement of equipment and personnel within the stream channel or on sand and gravel bars, banks, and adjacent upland habitats used by target species of concern. vi. Projects that cannot be conducted without placing equipment or personnel in sensitive habitats should be timed to avoid the breeding season of riparian bird species identified in MSHCP Global Species Objective No. 7. vii. When stream flows must be diverted, the diversions shall be conducted using sandbags or other methods requiring minimal instream impacts. Silt fencing of other sediment trapping materials shall be installed at the downstream end of construction activity to minimize the transport of sediments off site. Settling ponds where sediment is collected shall be cleaned out in a manner that prevents the sediment from reentering the stream. Care shall be exercised when removing silt fences, as feasible, to prevent debris or sediment from returning to the stream. viii. Equipment storage, fueling, and staging areas shall be located on upland sites with minimal risks of direct drainage into riparian areas or other sensitive habitats. These designated areas shall be located in such a manner as to prevent any runoff from entering sensitive habitat. Necessary precautions shall be taken to prevent the release of cement or other toxic substances into surface waters. Project related spills of hazardous materials shall be reported to appropriate entities including but not limited to applicable jurisdictional city, FWS, and CDFG[CDFW], RWQCB and shall be cleaned up immediately and contaminated soils removed to approved disposal areas. ix. Erodible fill material shall not be deposited into water courses. Brush, loose soils, or other similar debris material shall not be stockpiled within the stream channel or on its banks. x. The qualified project biologist shall monitor construction activities for the duration of the project to ensure that practicable measures are being employed to avoid incidental disturbance of habitat and species of concern outside the project footprint. xi. The removal of native vegetation shall be avoided and minimized to the maximum extent practicable. Temporary impacts shall be returned to pre-existing contours and revegetated with appropriate native species. xii. Exotic species that prey upon or displace target species of concern should be permanently removed from the site to the extent feasible.

8 RCA Joint Project Review (JPR) JPR #: 18-08-30-01 Date: 03/23/2021 xiii. To avoid attracting predators of the species of concern, the project site shall be kept as clean of debris as possible. All food related trash items shall be enclosed in sealed containers and regularly removed from the site(s). xiv. Construction employees shall strictly limit their activities, vehicles, equipment, and construction materials to the proposed project footprint and designated staging areas and routes of travel. The construction area(s) shall be the minimal area necessary to complete the project and shall be specified in the construction plans. Construction limits will be fenced with orange snow screen. Exclusion fencing should be maintained until the completion of all construction activities. Employees shall be instructed that their activities are restricted to the construction areas. xv. The Permittee shall have the right to access and inspect any sites of approved projects including any restoration/enhancement area for compliance with project approval conditions, including these BMPs.
