Regarding the commenter’s assertion that there are discrepancies between the IS/MND and the Sunset Crossroads EIR, “evidence of environmental impacts must be founded upon facts in the administrative record” for the particular project being approved. CEQA Guidelines, § 15384(a); Pocket Protectors v. City of Sacramento (2004) 124 Cal. App. 4th 903, 927. CEQA does not require that an IS/MND compare its analysis with analysis from a different uncertified environmental document, analyzing a different project altogether.

This comment does not change any of the significance determinations made in the MND and it does not raise any new environmental issues. No further analysis is required.

Response to Comment B-18
This comment suggests the IS/MND does not describe the future intersection improvements fully enough.

A plan-view image of the proposed intersections at Highland Home Road and Sunset Avenue based on the engineering plans for the project is enclosed on pages 1 and 2 of Attachment 1 (Images 1 and 2). The design of the Project, which includes the intersections, is consistent with the City standards, County of Riverside standards, and California Department of Transportation (Caltrans) standards for roadway design and safety. Roadway design standards for safety are generally based on the driver’s ability to have sufficient site distance along roads and at turning points/intersections/driveways. Because the Project has been engineered according to the accepted standards and vetted through City staff and their professional consultants through several reviews, which is the normal process for all roadway improvements in the City, there should be no reason to suggest the design is inherently flawed in regard to safety at the intersections.

Image 1 of Attachment 1 identifies Whirlwind Circle, which is an entrance to the Serrano Del Vista development, to which the commentor refers. The proposed road improvements of the Project along Sunset Avenue were also designed consistent with the aforementioned design standards. Presumably Whirlwind Circle was also designed and constructed consistent with design standards. With-Project traffic volumes on Sunset Avenue are measured by levels of service (LOS). LOS was calculated in a Traffic Impact Analysis for the project to inform the City on needed roadway improvements, to inform the Noise Impact Analysis, and to inform the Air Quality/Greenhouse Gas Analysis for the Project. Although LOS was once a CEQA metric for traffic/transportation impacts, as of July 1, 2020, the metric for CEQA traffic/transportation impacts changed to vehicle miles traveled (VMT).8 CEQA Guidelines Section 15064.3 mandates that CEQA review of transportation impacts be modified by eliminating consideration of delayand capacity-based metrics such as LOS. Since LOS is no longer a CEQA threshold, a discussion of this topic in the IS/MND is not appropriate. The publicly circulated IS/MND appropriately discloses the results of the VMT analysis on pages 104–105.

The commentor suggests there could be a risk to safety where Sun Lakes Boulevard meets Westward Avenue at Sunset Avenue. No risk to safety has been identified as a result of the street name changing. Although this is not a comment pertaining to an environmental concern, the Project will be named Sun Lakes Boulevard and changes to Westward Avenue east of Sunset Avenue.

This comment does not change any of the significance determinations made in the MND and it does not raise any new environmental issues. No additional analysis is required.

Response to Comment B-19
This comment questions the determination in the Mandatory Findings thresholds of the IS/MND that all potentially significant impacts have been identified.

Despite the changes made to the IS/MND as described in the responses to Comments B-1 – B-18 that amplify and clarify the analysis, no new potentially significant impacts were identified and the IS/MND continues to conclude that all potentially significant impacts have been 8 CEQA Guidelines Section 15064.3

Response to Comment Letter C – Morongo Band of Mission Indians This comment letter was received after the end of the public review period.

Response to Comment C-1
This comment acknowledges the Tribe’s receipt of the IS/MND and noted the Project is located “within the ancestral territory and traditional use area of the Cahuilla and Serrano people of the Morongo Band of Mission Indians.” This comment also recommends “tribal participation (aka tribal monitors)” during all ground disturbing activities.

As stated on pages 106-107 of the publicly circulated IS/MND, no tribal cultural resources were identified during the Project’s AB 52 process; nonetheless in response to the Morongo Band of Mission Indians’ (MBMI) request mitigation measure MM CR-1 will be modified in the Final IS/MND as follows:

MM CR-1: Monitoring and Inadvertent Discovery. Prior to the start of construction, the City shall retain a qualified archaeologist to monitor all ground disturbing activities. The City shall also work with the Morongo Band of Mission Indians to enter into an agreement for a Tribal Monitor prior to the start of construction. In the event archaeological resources are discovered during Project construction that are not part of Site 33-013779 (CA-RIV-7544) and Site 33- 013788, all ground disturbance activities within 100 feet of the discovered archaeological resource shall be halted until a qualified archaeologist (meeting the Secretary of the Interior Standards) can visit the site of discovery, assess the significance and integrity of the find, and determine the appropriate treatment (documentation, recovery, avoidance, etc.) and disposition of the cultural resource. Further ground disturbance shall not resume within the area of discovery until the appropriate treatment has been accomplished. Work on the other portions of the Project outside of the buffered area may continue. Any such discoveries and subsequent evaluation and treatment shall be documented and submitted to the Eastern Information Center (EIC) for archival purposes.

The modification of mitigation measure MM CR-1 does not change any of the significance determinations made in the MND and it does not raise a new environmental issue. Modification of mitigation measure MM CR-1 does not constitute new information that would require recirculation pursuant to Section 15073.5 of the CEQA Guidelines. No further analysis is required.

Response to Comment C-2
This comment requests to initiate government-to-government consultation under SB 18 and AB 52. This comment also requests a copy of the current Project design and Mass Grading Maps, and tribal participation (aka tribal monitors) during the pedestrian survey unless it has been completed already. If the pedestrian survey has been completed, then the Morongo Band of Mission Indians (MBMI) requests a copy of the current Phase 1 cultural resources study and shapefiles of the Project’s Area of Potential Effect (APE). 1012

Senate Bill (SB) 18, requires local governments to notify and consult with California Native American tribes when the local government is considering adoption or amendment of a general or specific plan. The proposed Project does not include adoption or amendment of the City’s General Plan of any specific plan; therefore, SB 18 is not applicable.

Regarding Assembly Bill (AB) 52 consultation, this process includes specific timeframes by which any Native American Tribe interested in consultation must respond to a Lead Agency’s request and when consultation must commence. Per Public Resources Code (PRC) § 21080.3.1(b), the Native American Tribe has 30 days to respond (in writing) to a Lead Agency’s notification of consultation opportunity and the CEQA Lead Agency has 30 days after receiving the request for consultation to begin the consultation process. If a Native American Tribe does not respond within the 30-day period, there are no further consultation requirements. In part, the purpose of the 30-day period is to provide certainty, so that a lead agency may proceed with the CEQA process once the 30-day period runs if no consultation request is made.

As discussed on page 106 of the publicly circulated IS/MND, representatives of the City and WEBB (as the City’s consultant) met virtually with the Morongo Band of Mission Indians’ (MBMI) Tribal Historic Preservation Officer (THPO) (Bernadette Ann Brierty) on October 15, 2020 to introduce the Project and provide background regarding the prior SB 18 and AB 52 consultation efforts conducted and completed by the City and MBMI for General Plan Amendment No. 19-2502. On that same date, the results of the Project’s Phase 1 Cultural Resource Assessment (CRA) records search were provided to the MBMI THPO. On December 3, 2021, the Phase I CRA was provided to the MBMI THPO. WEBB, on the City’s behalf, made follow-up phone calls to the MBMI THPO in January and February 2021 and received no return calls. City staff followed up with the MBMI THPO in September 2021 and since there was no response from MBMI, the City appropriately concluded consultation on November 15, 2021, over one year after meeting with the MBMI THPO. No tribal cultural resources were identified during the AB 52 consultation process.

Regarding the request to participate in pedestrian surveys, these surveys have been completed. Pedestrian surveys of the Project site were conducted on September 4, 2020, March 31, 2022, and April 3, 2024. The Project’s Phase 1 CRA (included as IS/MND Appendix C) was updated in April 2024 to include a larger survey area. No cultural resources were found during the 2024 survey of the additional impact area. Regarding the request for a copy of the current Phase I CRA, that document was included as Appendix C of the IS/MND.

Further, since Comment C-2 states the Tribe has a copy of the Phase 1 CRA, the City will not send another copy. Regarding the request for the current engineering plans and shapefiles of the Project footprint/Area of Potential Effect (APE), the City will transmit those to the MBMI THPO. The Project does not involve mass grading. The amplification of the Project description by providing MBMI the engineering plans and shapefiles of the APE does not constitute new information that would require recirculation pursuant to Section 15073.5 of the CEQA Guidelines.

This comment does not change any of the significance determinations made in the MND and it does not raise a new environmental issue.

Response to Comment C-3
This comment acknowledges a federal nexus with U.S. Army Corps of Engineers and therefore a Section 106 consultation is a component of the Project.

The comment regarding a federal nexus with the U.S. Army Corps of Engineers (USACE) is incorrect. In August 2023 the definition of Waters of the U.S. changed and no longer includes ephemeral creeks like the creeks impacted by the Project. As discussed in IS/MND Response IV.b Biological Resources, the Project Site includes three existing ephemeral drainages, Highland Wash, Smith Creek, and Pershing Creek. None of these drainages have permanent flow and are therefore not considered USACE jurisdictional. (IS/MND, pp. 43–44.) That the Project will not impact USACE jurisdictional waters is stated again on page 45 of the IS/MND, “Based on the current definition of Waters of the U.S., the Project will not impact Waters of the U.S. and will therefore not require a Section 404 permit from the U.S. Army Corps of Engineers.” This comment does not change any of the significance determinations made in the IS/MND and it does not raise a new environmental issue.

Response to Comment C-4
This comment indicates the Tribe does not consider AB 52 consultation concluded and may provide further recommendations and/or mitigation measures after receiving the requested documents. Communications can be sent to the individuals noted.

As discussed in Response to Comment C-2 and on page 106 of the publicly circulated IS/MND, the City concluded AB 52 consultation. Nonetheless, the City will provide copies of the requested documents to the individuals noted. This comment does not change any of the significance determinations made in the MND and it does not raise a new environmental issue. 1014

Project Description
The Project is located within the City adjacent to unincorporated territory of Riverside County. The alignment of the Project is in the western portion of the City, south of Interstate 10 (I-10), between the intersections of South Highland Home Road to the west and Sunset Avenue to the east.

The Project will construct a new section of Sun Lakes Boulevard from South Highland Home Road to Sunset Avenue and intersection improvements consistent with General Plan Amendment (GPA) 19-2502.

The Project is approximately 5,400 linear feet (1.02 mile) long and 110-feet wide, encompassing approximately 19.4 acres of direct footprint and an additional approximately 9.1 acres of temporary construction disturbance area. Project staging and stockpiling will occur within the City’s rights-ofway (ROW). Sun Lakes Boulevard will be constructed according to the City’s General Plan Typical Section for an Arterial Highway, with two eastbound and two westbound lanes, each containing a 12-feet wide lane and a 14-feet wide lane; a raised 18-foot wide median; eastbound and westbound 8-foot-wide bike lanes; 8-foot-wide sidewalks; associated road striping, drainage, and street light improvements. The Project also includes drainage improvements and the City’s acquisition of approximately 621,000 square-feet (SF) of ROW, approximately 143,000 SF of drainage easements, and approximately 44,000 SF of pipeline easements.

MM BIO-1: Vegetation Clearance and Preconstruction Nesting Bird Survey. To avoid direct and indirect impacts to nesting birds, any Project-related ground disturbance/vegetation clearance must take place between September 1 and February 1. For
preconstruction nesting bird surveys, if vegetation clearance does not occur within the September 1 to February 1 timeframe, then a preconstruction nesting bird survey would be required. A qualified biologist shall conduct a nesting bird survey(s) no more than three (3) days prior to initiation of construction to document the presence or absence of nesting birds within or directly adjacent (100 feet) to the Project Site. The nesting bird survey(s) would focus on identifying any passerine or raptor nests that would be directly or indirectly affected by construction activities. If active bird nests are documented, species-specific measures shall be prepared by a qualified biologist and implemented to prevent abandonment of the active bird nest. At a minimum, grading in the vicinity of a nest shall be deterred until the young birds have fledged. A minimum exclusion buffer of 100 feet shall be maintained during construction, depending on the species and location. The perimeter of the nest setback zone shall be fenced or adequately demarcated with stakes and flagging at 20-foot intervals, and construction personnel and activities restricted from the area. A survey report by a qualified biologist verifying that no active nests are present, or that the young have fledged, shall be submitted to the City of Banning for review and approval prior to initiation of construction in the nest-setback zone. The qualified biologist shall serve as a construction monitor during those periods when construction activities occur near active nest areas to ensure that no inadvertent impacts on these nests occur.

MM BIO-2: Burrowing Owl Survey. To avoid direct and indirect impacts to burrowing owls, a qualified biologist shall conduct a minimum one visit 30-day burrowing owl preconstruction survey of all suitable habitat that is slated for any vegetation removal, grading, or other disturbance in the Project site. The burrowing owl survey shall be conducted to ensure protection for this species and compliance with the conservation goals as outlined in the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) and according to the MSHCP “Burrowing Owl Survey Instructions” dated 2006. A report of the survey findings prepared by a qualified biologist shall be submitted to the City of Banning and County of Riverside Environmental Programs Division (Riverside County EPD) for review and approval prior to any ground disturbing activities. If burrowing owls are detected on the Project Site during the 30-day preconstruction survey, and during the breeding season (February 1st to August 31st), then construction activities shall be limited to beyond 300 feet of the active burrows until a qualified biologist has confirmed that nesting efforts are competed or not initiated. In addition to monitoring breeding activity, if construction is proposed to be initiated during the breeding season or active relocation is proposed, a burrowing owl mitigation plan will be developed based on the Riverside County EPD, CDFW, and United States Fish and Wildlife Service (USFWS) requirements for the relocation of individuals. Passive relocation may occur when owls are found onsite during preconstruction surveys conducted outside of the breeding season. If no owls are found onsite during the Survey within 30

MM BIO-3: Crotch’s Bumble Bee Survey and Construction
Monitoring. In order to avoid direct and indirect impacts to Crotch’s bumble bee (CBB) which could establish themselves on the Project site before construction starts, a qualified CBB biologist (i.e., 1-2 years of experience performing CBB surveys, or, has a Memorandum of Understanding [MOU] with CDFW), shall perform the records searches and site surveys according to the Survey Considerations for California Endangered Species Act Candidate Bumble Bee Species (CDFW 2023) prior to the start of grounddisturbing project activities. The literature review and records search shall identify occurrences at the Project site and within a 5- mile buffer. The literature review and records search shall include: a report from the CDFW California Natural Diversity Data Base for a 10-mile radius of the project site; aerial photographs; and iNaturalist for bee sightings and nectar sources. Then, the qualified biologist shall conduct on-site surveys for foraging and nesting bees. The surveys shall begin with a habitat assessment to evaluate the likelihood of bumble bees occurring within and adjacent to the project area. Then, foraging bumble bee and nesting surveys shall be conducted during the peak nectar blooming period (April through June 30). Habitat assessment and survey results shall be submitted to CDFW prior to the start of ground-disturbing project activities. Vegetation removal is allowable from November to January (note seasonal limitations for nesting birds in MM BIO-1).

disturbances during the CBB flight season, which is February to October, will require preemptive focused CBB surveys and full-time biological monitoring for CBB to take place within the project limits.

Construction monitoring for CBB may cease based on the
professional judgement of the qualified CBB biologist that construction activities have already impacted the extent of the planned impact footprint. If an active CBB nest is detected during focused surveys conducted between April and June, or during the construction monitoring, then the qualified biologist shall establish a no-disturbance buffer zone (including foraging resources and flight corridors essential for supporting the colony) around the CBB nest. The qualified biologist and City shall notify CDFW and if needed, process an Incidental Take Permit (ITP) with CDFW. If a single CBB is observed during construction, CDFW shall be notified, and work shall be halted in that area until the qualified biologist deems the CBB has left the site. It is expected that if an ITP is needed, that the offsite mitigation site along Smith Creek proposed by MM BIO-5, which has similar habitat types and embankments, could support CBB. If offsite mitigation for CBB is needed, then a CBB permitted land manager shall be hired by the City to ensure CBB habitat is intact on the offsite mitigation property.

MM GEO-1: Paleontological Worker Environmental Awareness Program (WEAP). To educate construction crews about the types of paleontological resources that may be encountered along the Sun Lakes Boulevard Extension Project, prior to the start of the construction, the City of Banning shall retain a professional paleontologist (the “Project Paleontologist”) to prepare a Paleontological Worker Environmental Awareness Program (WEAP).

The Paleontological WEAP shall provide a description of the laws and ordinances protecting fossil resources, the types of fossil resources that may be encountered in the area, the role of the paleontological monitor, outline steps to follow in the event that a fossil discovery is made and provide contact information for the Project Paleontologist. The Project Paleontologist or designee(s) shall present the Paleontological WEAP to the construction contractor and each of the construction crews working on the Sun Lakes Boulevard Extension Project during a preconstruction meeting. The Paleontological WEAP shall be taped and presented to any construction crew members not present at the preconstruction meeting during which it was initially presented prior to such crew members working on the Sun Lakes Boulevard Extension Project.

This training may be conducted concurrent with other
preconstruction training (e.g., biological resources, safety).

2. Fossil Preparation and Curation. The PRIMP (MM GEO-2) shall identify the museum that has agreed to accept fossils that may be discovered during project-related excavations. Upon completion of fieldwork, all significant fossils collected shall be prepared in a properly equipped laboratory to a point ready for curation.

Preparation may include the removal of excess matrix from fossil materials and stabilizing or repairing specimens. During preparation and inventory, the fossil specimens will be identified to the lowest taxonomic level practical prior to curation at an accredited museum.

The fossil specimens must be delivered to the accredited museum or repository no later than 90 days after all fieldwork is completed.

The cost of curation will be assessed by the repository and will be the responsibility of the City of Banning.

3. Final Paleontological Mitigation Report. Upon completion of ground disturbing activities (and curation of fossils if necessary) for the Sun Lakes Extension Project, the Project Paleontologist shall prepare a final report documenting the WEAP (MM GEO-1) and outlining the results of the PRIMP (MM GEO-2). The report shall include discussion of the location, duration, and methods of monitoring, stratigraphic sections, any recovered fossils, and the scientific significance of those fossils, and where fossils were curated.

NOTICE OF INTENT TO ADOPT A MITIGATED NEGATIVE DECLARATION Project Title: Sun Lakes Boulevard Extension Project
NOTICE IS HEREBY GIVEN that the City of Banning (City), as Lead Agency under the California Environmental Quality Act (CEQA), has prepared a Notice of Intent (NOI) to adopt a Mitigated Negative Declaration (MND) for the proposed Sun Lakes Boulevard Extension Project (“Project”). The MND has been prepared pursuant to CEQA and the CEQA Guidelines.

Copies of available materials may be reviewed or obtained from the City’s website (www.banningca.gov) as well as the Bulletin Board at Banning City Hall, located at 99 E Ramsey Street, Banning, CA 92220. The documents will also be available electronically through the State Clearinghouse (https://ceqanet.opr.ca.gov/).

Project Location: The Project is located within the City adjacent to unincorporated territory of Riverside County. The alignment of the Project is in the western portion of the City, south of Interstate 10 (I-10), between the intersections of South Highland Home Road to the west and Sunset Avenue to the east. Refer to Figure 1.

Project Description: The Project will construct a new section of Sun Lakes Boulevard from South Highland Home Road to Sunset Avenue and intersection improvements consistent with General Plan Amendment (GPA) 19-2502. The Project is approximately 5,400 linear feet (1.02 mile) long and 110-feet wide, encompassing approximately 19.4 acres of direct footprint and an additional approximately 9.1 acres of temporary construction disturbance area. Project staging and stockpiling will occur within the City’s rights-of-way (ROW). Sun Lakes Boulevard will be constructed according to the City’s General Plan Typical Section for an Arterial Highway, with two eastbound and two westbound lanes, each containing a 12- feet wide lane and a 14-feet wide lane; a raised 18-foot wide median; eastbound and westbound 8-foot-wide bike lanes; 8-foot-wide sidewalks; associated road striping, drainage, and street light improvements. The Project also includes drainage improvements and the City’s acquisition of approximately 621,000 square-feet (SF) of ROW, approximately 143,000 SF of drainage easements, and approximately 44,000 SF of pipeline easements.

Environmental Issues: Environmental issues addressed in the MND include aesthetics; agricultural and forestry resources; air quality; biological resources; cultural resources; energy; geology and soils, greenhouse gas emissions; hazards and hazardous materials; hydrology and water quality; land use and planning; mineral resources; noise; population and housing; public services; recreation; transportation; tribal cultural resources; utilities and service systems; and wildfire.

Environmental Effects: The Initial Study Checklist determined that the Project would result in potentially significant effects, but with implementation of recommended mitigation measures that would avoid or mitigate effects to a point where clearly no significant environmental impacts on the environment will occur. Mitigation has been included to address Biological Resources, Cultural Resources, and Geology/Soils (Paleontological) Resources.

Public Review Period: The MND will be available for a 30-day public review period from Friday, September 6, 2024 to Monday October 7, 2024.

From: Eliza Laws, Senior Environmental Analyst
Noemi Avila, Assistant Environmental Analyst
Date: November 2, 2021
Re: Air Quality/Greenhouse Gas Analysis for Sun Lakes Boulevard Extension Project in the City of Banning, County of Riverside, California
The following air quality assessment was prepared to evaluate whether the expected criteria air pollutant emissions generated as a result of construction and operation of the proposed Project would cause exceedances of the South Coast Air Quality Management District (SCAQMD) thresholds for air quality in the Project area. The greenhouse gas (GHG) assessment was prepared to evaluate whether the expected GHG emissions generated as a result of construction and operation of the proposed Project would exceed the SCAQMD draft screening significance thresholds. This assessment was conducted within the context of the California Environmental Quality Act (CEQA, California Public Resources Code Sections 21000 et seq.). The methodology follows the CEQA Air Quality Handbook prepared by the SCAQMD for quantification of emissions and evaluation of potential impacts to air resources. As recommended by SCAQMD staff, the California Emissions Estimator Model® version 2020.4.0 (CalEEMod) was used to quantify Project-related emissions.

The proposed Sun Lakes Boulevard Extension Project (Project) will improve the existing Sun Lakes Boulevard, an unpaved road running in an east-west direction between the intersections of South Highland Home Road to the west and Sunset Avenue to the east, in the City of Banning. The Project alignment is approximately one mile long, and the existing right-of-way is 110-feet wide. The Project will be constructed with 4-lanes (two lanes in each direction), 8-foot bike lanes, 8-foot sidewalks, associated road striping, street light improvements, two traffic signals, intersection improvements, and existing power pole relocation. The Project also proposes drainage improvements that are consistent with the City’s Master Drainage Plan (MDP). The total construction footprint, inclusive of drainage improvements, proposed right-of-way, temporary grading, and staging area is approximately 23 acres.  Regional Significance Thresholds
The thresholds contained in the SCAQMD CEQA Air Quality Handbook1 (SCAQMD 1993) are considered regional thresholds and are shown in Table 1 – SCAQMD CEQA Daily Regional Significance Thresholds, below. These regional thresholds were developed based on the SCAQMD’s treatment of a major stationary source.
1 South Coast Air Quality Management District, CEQA Air Quality Handbook, November 1993. (Available at SCAQMD.) 1070
2 Table 1 – SCAQMD CEQA Daily Regional Significance Thresholds Emission
Threshold Units VOC NOX CO SOX PM-10 PM-2.5
Construction lbs/day 75 100 550 150 150 55
Operation1 lbs/day 55 55 550 150 150 55
Air quality impacts can be described in a short- and long-term perspective. Short-term impacts occur during site grading and Project construction and consist of fugitive dust and other particulate matter, as well as exhaust emissions generated by construction-related vehicles. Long-term impacts occur once the Project is in operation. Operational emissions would primarily be from infrequent visits by vehicles driven by maintenance personnel and are considered negligible; therefore, only short-term impacts were quantified.

The Project will be required to comply with existing SCAQMD rules for the reduction of fugitive dust emissions. SCAQMD Rule 403 establishes these procedures. Compliance with this rule is achieved through application of standard best management practices in construction and operation activities, such as application of water or chemical stabilizers to disturbed soils, managing haul road dust by application of water, covering haul vehicles, restricting vehicle speeds on unpaved roads to 15 mph, sweeping loose dirt from paved site access roadways, cessation of construction activity when winds exceed 25 mph and establishing a permanent, stabilizing ground cover on finished sites. In addition, projects that disturb 50 or more acres or more of soil or move 5,000 cubic yards of materials per day are required to submit a Fugitive Dust Control Plan or a Large Operation Notification Form to SCAQMD.

Based on the size of this Project’s disturbance area (approximately 23.47 acres) a Fugitive Dust Control Plan or a Large Operation Notification Form would not be required.

Short-Term Analysis
Short-term emissions from Project construction were evaluated using the CalEEMod version 2020.4.0 program. The estimated construction period for the proposed Project is approximately 18 to 24 months, beginning no sooner than February 2023. A duration of 24 months was evaluated to provide a worstcase analysis. The default parameters within CalEEMod were used and these default values reflect a worst-case scenario, which means that Project emissions are expected to be equal to or less than the estimated emissions. In addition to the default values used, assumptions relevant to model inputs for short-term construction emission estimates used are:
• Construction is anticipated to begin in February 2023, which will include construction activities such as utility relocation, installation of drainage improvements, roadway improvements, and traffic signal installation and paving. Because the schedule is unknown, the grading and paving activities were assumed to occur concurrently throughout the estimated construction duration to provide a conservative analysis. The estimated construction schedule is shown below:

Construction Activity Start Date End Date Total Working Days
Grading February 01, 2023 January 31, 2025 523
Paving February 01, 2023 January 31, 2025 523
• The off-road equipment to be used for each activity is shown below and represents program defaults. Each piece of equipment is assumed to operate 8 hours per day:

Grading Excavators 2
Grader 1
Rubber Tired Dozer 1
Tractors/Loaders/Backhoes 2
Scrapers 2
Paving Pavers 2
Paving Equipment 2
Rollers 2
• To evaluate Project compliance with SCAQMD Rule 403 for fugitive dust control, the Project utilized the mitigation option of watering the Project site three times daily which achieves a control efficiency of 61 percent for PM-10 and PM-2.5 emissions. Two (2) one-way vendor trips per day were added to the grading and paving activity to account for water truck trips. • Eight (8) one-way hauling truck trips per day were included during paving to account for material delivery.
• Approximately 98,180 cubic yards of soil import is required for the Project. The import site is currently unknown. Therefore, the CalEEMod default was utilized with assumes a hauling trip length of 20 miles per trip. Based on the CalEEMod default truck capacity of 16 cubic yards, approximately 6,136 truckloads of soil would be imported.

The results of this analysis are summarized below.

As shown in the table above, the emissions from construction of the Project are below the SCAQMD daily construction thresholds for all the criteria pollutants. 1072
4  Localized Significance Threshold Analysis
Background
As part of the SCAQMD’s environmental justice program, attention has been focused on localized effects of air quality. Staff at SCAQMD has developed localized significance threshold (LST) methodology2 that can be used by public agencies to determine whether or not a project may generate significant adverse localized air quality impacts (both short- and long-term) to sensitive receptors.

SCAQMD considers a sensitive receptor to be a location where a sensitive individual could remain for 24 hours, such as residences, hospitals, or convalescent facilities. LSTs represent the maximum emissions from a project that will not cause or contribute to an exceedance of the state ambient air quality standard, and are developed based on the ambient concentrations of that pollutant for each source receptor area (SRA). The Project site is located in SRA 29.

Short-Term Analysis
According to the LST methodology, only on-site emissions need to be analyzed. Emissions associated with vendor and worker trips are mobile source emissions that occur off site. The emissions analyzed under the LST methodology are NO2, CO, PM-10, and PM-2.5. SCAQMD has provided LST lookup tables3 to allow users to readily determine if the daily emissions for proposed construction or operational activities could result in significant localized air quality impacts for projects five acres or smaller. The Project’s total disturbance area is approximately 23.47 acres. However, based on SCAQMD guidance, the daily disturbance area is approximately 3 acres.4 Therefore, the two-acre LST Look-Up Table was compared with the on-site emissions estimated by CalEEMod to provide a conservative analysis.

The LST thresholds are estimated using the maximum daily disturbed area (in acres) and the distance of the Project to the nearest sensitive receptors (in meters). The closest sensitive receptors are residential houses adjacent to each end of the Project alignment. The closest receptor distance on the LST look-up tables is 25 meters. According to LST methodology, projects with boundaries closer than 25 meters to the nearest receptor should use the LSTs for receptors located at 25 meters. Therefore, a receptor distance of 25 meters (82 feet) was used to ensure a conservative analysis. The results are summarized below.

Emissions from construction of the Project will be below the LST established by SCAQMD for the Project.

Long-Term Analysis
This Project involves the construction of roadway and drainage improvements. According to SCAQMD LST methodology, LSTs would apply to the operational phase of a project, if the project includes stationary sources (e.g., flares and turbines) and/or on-site mobile equipment or attracts mobile sources that may spend long periods of time idling at the site, such as warehouse/transfer facilities. The proposed Project does not include such uses. Therefore, due to the lack of stationary source emissions or on-site mobile equipment, no long-term LST analysis is needed.  Greenhouse Gas Analysis
Greenhouse gases (GHG) are not presented in lbs/day like criteria pollutants; they are typically evaluated on an annual basis using the metric system. Additionally, unlike the criteria pollutants, GHG do not have adopted significance thresholds associated with them at this time. Several agencies, at various levels, have proposed draft GHG significance thresholds for use in CEQA documents. SCAQMD has been working on GHG thresholds for development projects. The most recent draft proposal was in September 20105 and included significance thresholds for residential, commercial, and mixed-use projects at 3,500, 1,400, and 3,000 metric tonnes per year of carbon dioxide equivalents (MTCO2E/yr), respectively.

Alternatively, a lead agency has the option to use 3,000 MTCO2E/yr as a threshold for all non-industrial projects. Although both options are recommended by SCAQMD, a lead agency is advised to use only one option and to use it consistently. In December 2008, the SCAQMD adopted a threshold of 10,000 MTCO2E/yr for stationary source projects where SCAQMD is the lead agency. The SCAQMD significance thresholds evaluate construction emissions by amortizing them over an expected project life of 30 years. The analysis herein uses the threshold of 3,000 MTCO2E/yr.

The CalEEMod output results for construction-related GHG emissions present the GHG emissions estimates for the Project for CO2, methane (CH4), nitrous oxide (N2O), and CO2E.6 Short-Term Analysis
Construction-Related Emissions
The CalEEMod model calculates GHG emissions from fuel usage by construction equipment and construction-related activities, like construction worker trips, for the Project. The CalEEMod estimate does not analyze emissions from construction-related electricity or natural gas. Construction-related electricity and natural gas emissions vary based on the amount of electric power used during construction and other unknown factors which make them too speculative to quantify. 5 http://www.aqmd.gov/docs/default-source/ceqa/handbook/greenhouse-gases-(ghg)-ceqa-significance-thresholds/year-2008- 2009/ghg-meeting-15/ghg-meeting-15-main-presentation.pdf?sfvrsn=2 6 CO2E is the sum of CO2 emissions estimated plus the sum of CH4 and N2O emissions estimated multiplied by their respective global warming potential (GWP).

Note: 1 Construction emissions were amortized over a 30-year period, as recommended by SCAQMD.

Evaluation of the table above indicates that an estimated 2,513.80 MTCO2E will occur from Project construction equipment over the course of the estimated construction period. The draft SCAQMD GHG threshold guidance document released in October 20087 recommends that construction emissions be amortized for a project lifetime of 30 years to ensure that GHG reduction measures address construction GHG emissions as part of the operational reduction strategies. Therefore, the total GHG emissions from Project construction were amortized and are included in Table 5, below.

Long-Term Analysis
Energy-Related Emissions
CalEEMod estimates the GHG emissions associated with building electricity and natural gas usage for each land use type. Electricity and natural gas used in buildings is typically generated at an off-site power plant which indirectly generates GHG emissions. The indirect GHG emissions from the proposed street lighting were estimated in CalEEMod using the default electricity rate for parking lot lighting.

Utility-specific carbon intensity information from the City of Banning Electric Utility was used. 8 Table 5
summarizes the Project’s annual electricity emissions, which were reported as 21.87 MTCO2E per year.

Total Project GHG Emissions
As shown on Table 5 – Total Project-Related GHG Emissions, using the emissions quantified above, the total GHG emissions generated from the Project is approximately 105.66 MTCO2E/yr which includes construction-related emissions amortized over a typical project life of 30 years.

Total 21.73 0.00 0.00 105.66
Note: Emissions reported as zero are rounded and not necessarily equal to zero.

The total GHG emissions from the Project do not exceed the SCAQMD threshold of level of 3,000 MTCO2E/yr for non-industrial projects. Due to the estimated amount of emissions from Project construction and the proposed street light electricity usage as well as the negligible operational emissions from infrequent maintenance vehicles, the proposed Project will not generate GHG emissions that exceed the screening threshold.

The individual intensity factor for CO2, CH4, and N2O was derived based on data in the CalEEMod User’s Guide. 1075
7  Conclusion
The conclusion of this analysis indicates that construction and operation of the proposed Project will not exceed criteria pollutant thresholds established by SCAQMD on a regional or localized level. The Project will also not exceed the SCAQMD screening threshold. No mitigation is required.

1 EXECUTIVE SUMMARY
The proposed Sun Lakes Boulevard Extension Project (project) is a transportation project including construction of a new section of Sun Lakes Boulevard from Highland Home Road to Sunset Avenue (Figure 3) and intersection improvements within the city of Banning’s existing road right-ofway (ROW). The project encompasses approximately 19.4 acres of direct footprint (permanent impacts) and another 9.1 acres of temporary construction disturbance area (temporary impacts). Project staging and stockpiling will occur within the city’s ROW. The project site is located within the boundaries of the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) and this consistency analysis was performed in accordance with the requirements of the MSHCP.

The project site is not within any MSHCP Criteria Cells, Cell Groups, Cores, or Linkages. Studies required by the MSHCP include assessment for riparian/riverine/vernal pool resources, including a focused survey for fairy shrimp; a survey for the Narrow Endemic Plant Species (NEPS) Marvin’s (Yucaipa) onion (Allium marvinii) and many stemmed dudleya (Dudleya multicaulis); a survey for the burrowing owl (Athene cunicularia); a survey for the Los Angeles pocket mouse (Perognathus longimembris brevinasus); and an assessment of whether the Delhi Sands flower loving fly (Rhaphiomidas terminatus abdominalis) or any of twenty-eight (28) species which were not adequately conserved at the time of MSHCP implementation may be present on the project site.

To date, results of those studies include:
• Riparian/riverine habitat is present on the project site, including potential habitat for Cooper’s hawk (Accipiter cooperii) and possibly white-tailed kite (Elanus leucurus).
• Vernal pools are not present on the project site.
• Fairy shrimp habitat is present on the project site. Fairy shrimp focused surveys were completed on the project site during the 2020-2021 wet season and the 2021 dry season. The common versatile fairy shrimp (Branchinecta lindahli), which is not a special status species, was the only fairy shrimp species detected.
• Plant focused surveys were completed on the project site in 2020. No NEPS, riparian/riverine plant species, or plant species “not adequately conserved” were detected on the project site.
• Burrowing owl surveys were completed on the project site in 2020.

Burrowing owls were not detected on the project site.
• Los Angeles pocket mouse surveys sufficient to sample project site habitats, but not to delineate all occupied habitat, were conducted in 2020. Los Angeles pocket mice were not detected on the project site. 1159

• No soils suitable for Delhi Sands flower loving fly are present on the project site and the project area is well beyond the known range of the species. • The only wildlife species “not adequately conserved” which may occur as a breeding species on the project site is grasshopper sparrow (Ammodramus savannarum). It was not observed, but some suitable habitat is present.

The city intends to purchase land or preserve existing city land within the Whitewater Watershed, ideally along Smith Creek which would be placed in a conservation easement or have a deed restriction and protected in perpetuity with a non-wasting endowment. The land will be managed by a third-party land manager, such as Western Riverside County Regional Conservation Authority (RCA), Rivers and Lands Conservancy or Inland Empire Resource Conservation District. The purchased conservation land should contain similar habitat to the project site and provide similar or superior function and habitat value. Currently, the project site has relatively unvegetated, sandy bottom, riverine habitat. Any mitigation areas that contain riparian habitat would be considered superior habitat.

Permanent impacts will be mitigated at a 3:1 (3 x 0.37 = 1.11 acres) ratio and temporary impacts will be mitigated at a 2:1 ratio (2 x 0.09 = 0.18 acres). The total mitigation acreage should equal or surpass 1.3 acres. The primary method of mitigation will be offsite conservation and enhancement of City owned property located along Smith Creek. The City will place at least 1.3 acres into a Conservation Easement with an approved third party conservation holder such as Western Riverside County Regional Conservation Authority (RCA), Rivers and Lands Conservancy (RLC) or Inland Empire Resource Conservation District (IERCD). Additionally, the City has committed to participating in a regional solution of the sediment transport function of the Smith Creek watershed. The intended outcome of this regional solution is to bring the various stakeholders in this watershed together to work on a sediment management strategy to ensure sediment is transported efficiently and effectively to support ecological resources. The City’s commitment to this regional solution will serve as providing rehabilitation mitigation for the overall impacts from this Project.

The project will also return temporary impact areas to their pre-existing contours and revegetate them with appropriate native species. The project will also mitigate and/or minimize impacts by following MSHCP Section 6.1.4 Urban Wildlands Interface Guidelines and MSHCP Volume I, Appendix C Standard Best Management Practices (BMPs). Because burrowing owl habitat and potential burrows are present, a preconstruction survey will be conducted.

Should burrowing owls be detected at that time, an updated DBESP report will be prepared and mitigation will be achieved through the project following all MSHCP guidelines and the direction of the Environmental Programs 1160

7 2 INTRODUCTION
At the request of the Albert A. Webb Associates (Webb), WSP USA Inc. (WSP) prepared this Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) Consistency Analysis report for the proposed Sun Lakes Boulevard Extension Project (project). The purpose of this analysis is to summarize the biological data for the project and to document the project’s consistency with the goals and objectives of the MSHCP.

2.1 Project Area
The project is in the city of Banning, Riverside County, California and It is generally located south of Interstate 10, west of State Route 243 and east of Lambs Canyon Road (Figure 1). It can be found in Sections 7 and 18 of Township 3 South, Range 1 East of the Beaumont, California, United States Geological Survey (1978) 7.5-minute topographic quadrangle map (Figure 2). The elevation of the project site ranges from approximately 2,383 to 2,525 feet above sea level. The geographic coordinates near the middle of the site are 33.5512.85° North latitude and -116.5516.29° West longitude. The project occurs within portions of the following Assessor’s Parcel Numbers (APN): 419140039, 537110013, 537110014, 537120023, 537120024, 537120025, 537120027, 537120028, 537120029, 537120030, 537120031, 537120033, 537120034, 537140001, 537140002, 538323024, and 538323029.

No off-site staging areas or off-site improvements are planned. No weed abatement or fuel modification zones have been identified. However, if unforeseen circumstances were to arise that required hazard reduction within an area considered environmentally sensitive or a part of the MSHCP Conservation Area, such as lands proposed for conservation on the adjacent project site, it would require approval from the appropriate agencies prior to any vegetation management activities.

The proposed project is a transportation project including construction of a new section of Sun Lakes Boulevard from Highland Home Road to Sunset Avenue (Figure 3) and intersection improvements within the City of Banning’s existing and future road rightof-way (ROW). This report and associated figures have been updated to reflect the change in the area of the proposed impacts related to alignment revisions which have occurred so that the new roadway could be redesigned to avoid existing high pressure gas lines within the project area. The updated projects impacts include 19.4 acres of permanent impacts, 9.1 acres of temporary impacts. Project staging and stockpiling will occur within the City’s ROW. Currently, Westward Avenue is a straight east-west 1165
MSHCP Consistency Analysis
8 unpaved dirt road between Highland Home Road and Sunset Avenue. The project crosses over three creeks, from west to east: Highland Wash, Smith Creek, and Pershing Creek. The project will include the construction of three sets of culverts to cross said creeks.

Surrounding land uses include residential subdivisions, public facilities, and open space.

The approximately five-acres is currently undeveloped. Historically the project site was graded for agricultural purposes in the 1960’s. It has remained vacant for the past 2 to 3 decades. Vegetation within the proposed project site consists of non-native grassland, California buckwheat scrub, and Riversidean alluvial fan sage scrub. Three deeply incised drainages and associated tributaries are present within the proposed project site. Structures within the general vicinity include city-owned wells, an agricultural storage shelter, and several easements for streets, utilities, gas and oil pipelines, landscaping, and communications systems are all located within the general proposed project alignment.

2.3 General Setting
Adjacent to and south of the Sun Lakes Boulevard ROW are existing utilities that include three well sites and one wastewater lift station. Within Westward Avenue, there are many existing utility lines including, a potable water line, sanitary sewer line, recycled water line, fiber optics line, three oil lines, and an underground telephone line. Singlefamily homes are west of Highland Home Road. East of Sunset Avenue are single-family homes, a small number of commercial businesses, the Mt. San Jacinto College San Gorgonio Pass Campus, and undeveloped open space, including habitat for biological elements of concern to the MSHCP. The project footprint outside of the facilities detailed above is currently undeveloped open space, including habitat for biological elements of concern to the MSHCP, as are areas to the north and south of the project. 3 RESERVE ASSEMBLY ANALYSIS

3.1 Criteria Cells
No part of the project site lies within or adjacent to any MSHCP Criteria Cells. Therefore, the project will have no effect on the planned assembly of the MSHCP reserve.

3.2 Public Quasi-Public Lands
No part of the project site lies within or adjacent to any existing public quasi-public lands (PQP). Therefore, the project will have no effect on existing PQP lands. However, conservation is being proposed by an adjoining project immediately adjacent to proposed Sun Lakes Boulevard in Highland Wash, Smith Creek, Pershing Creek and in 1166

10 4 VEGETATION MAPPING
The project site contains six vegetation communities / land cover categories:
buckwheat scrub, non-native grassland, riparian scrub/woodland, Riversidean alluvial fan sage scrub, non-vegetated streambed, and disturbed/developed (Figure 4).

Disturbed/developed areas are the direct result of current or past human activity (buildings, roads, et cetera). The following are somewhat more natural land cover categories, although non-native grasslands are comprised largely of naturalized nonnative plant species introduced by humans:

Buckwheat Scrub
This habitat is dominated by California buckwheat (Eriogonum fasciculatum).

Additionally, vegetation includes California sagebrush (Artemisia californica), brittlebush (Encelia californica), pinebush (Ericameria pinifolia), deerweed (Acmispon glaber), common sand aster (Corethrogyne filaginifolia), turkey mullein (Eremocarpus setigerus), shortpod mustard (Hirschfeldia incana), and horseweed (Erigeron canadensis). Areas within the eroded dry stream areas adjacent to the active channel also contain rough cocklebur (Xanthium strumarium), Johnson grass (Sorghum halepense), and mugwort (Artemisia douglasiana).

Non-native Grassland
This habitat is dominated by non-native annual grasses. Some species of grasses that are observed within the grassland include wild oats (Avena fatua), cheatgrass (Bromus tectorum), and red brome (Bromus rubens). Dominant broad-leaved species within this habitat include shortpod mustard, red-stemmed filaree (Erodium cicutarium), and annual ragweed (Ambrosia acanthicarpa). Late summer dominants include turkeymullein and vinegarweed (Trichostema lanceolatum).

Non-vegetated Streambed
Although, not a vegetation community, it is a significant landscape feature found within the project site. The majority of the drainages within the project site contain mostly bare coarse sand with only isolated patches of vegetation including mule fat (Baccharis salicifolia), annual ragweed, shortpod mustard, and Johnson grass.

Riparian Scrub Woodland
This habitat is commonly dominated by young willow trees and shrubs. Within the project site, the riparian scrub woodland areas are small patches dominated by Fremont cottonwood (Populus fremontii), Goodding’s black willow (Salix gooddingii), red willow (Salix lasiolepis), or mule fat.
1168

11 Riversidean Alluvial Fan Sage Scrub
This is a ‘soft chaparral’ habitat found on south-facing upland slopes, and along sandy ephemeral streams. It occurs below 3,000 feet elevation and occupies generally drier sites than chaparral. Within the project site, scale broom (Lepidospartum squamatum) dominates. Other species observed include mugwort and tarragon (Artemisia dracunculus).

5 PROTECTION OF SPECIES ASSOCIATED WITH RIPARIAN/RIVERINE AREAS AND VERNAL POOLS (SECTION 6.1.2)
According to Section 6.1.2 of the MSHCP:
“Riparian/Riverine Areas are lands which contain habitat dominated by trees, shrubs, persistent emergents, or emergent mosses and lichens, which occur close to or which depend upon soil moisture from a nearby fresh water source; or areas with fresh water flow during all or a portion of the year.” and “Vernal pools are seasonal wetlands that occur in depression areas that have wetlands indicators of all three parameters (soils, vegetation and hydrology) during the wetter portion of the growing season but normally lack wetlands indicators of hydrology and/or vegetation during the drier portion of the growing season. Obligate hydrophytes and facultative wetlands plant species are normally dominant during the wetter portion of the growing season, while upland species (annuals) may be dominant during the drier portion of the growing season.”
“With the exception of wetlands created for the purpose of providing wetlands habitat or resulting from human actions to create open waters or from the alteration of natural stream courses, areas demonstrating characteristics as 1169
MSHCP Consistency Analysis
12 described above which are artificially created are not included in these definitions.”

5.1 Riparian/Riverine

5.1.1 Methods
On 29 July and 4 and 6 August 2020 and 25 March 2024, WSP senior biologist conducted a jurisdictional waters delineation (JD) of the project site. On 25 June 2024 WSP updated the JD report for the project site. The JD report is attached to this analysis as an appendix. Drainages were evaluated for wetland/riparian associated vegetation, clearly defined bed and bank features, wetland soils, and/or evidence of an ordinary high watermark that would potentially be considered jurisdictional by the U.S. Army Corps of Engineers, Regional Water Quality Control Board, CDFW, and/or MSHCP.

5.1.2 Existing Conditions and Results
The following riparian/riverine resources were identified on-site:

Highland Wash is an ephemeral drainage containing riparian and riverine resources that flows from north to south and crosses perpendicular to the proposed project. Flow originates from north of Interstate 10 and from the Sun Lakes community immediately northwest of the project. In the area of the project, Highland Wash contains an active low flow channel with adjacent active floodplain that is bordered on the west with low terraces and on the east are incised channel walls that are both bordered by uplands. The active low-flow channel is approximately 12-inches wide in the project area with a silty/sandy bed and no vegetation. Evidence of flows were identified by benches and drift present in the project area. The adjacent active floodplain varies from roughly 3-feet to 15-feet wide and evidenced by a more pebbly substrate then the low flow channel, as well as ripples, older drift, presence of bed and bank, benches and no vegetation. The ordinary high water mark (OHWM) is approximately 8-inches and indicated by break in slope and change in vegetative cover from active floodplain to low terrace. The low terrace borders the floodplain on the west with midstage upland vegetation consisting of California buckwheat that uniformly dominates the drainage area from the low terrace to the nearby hill tops. The outer limit of the low terrace is characterized by a higher vegetative density of buckwheat and marks the limit of potential CDFW jurisdiction.

Highland Wash likely flows for less than 3 months months per year and is therefore does not have permanent flow and would not be considered USACE jurisdictional. Highland Wash joins with Smith Creek at Westward Avenue. 1170
MSHCP Consistency Analysis
13 Smith Creek is an ephemeral drainage containing riparian and riverine resources that flows from north to south and crosses perpendicular to the proposed project and east of Highland Wash. Flow to Smith Creek originates from a large watershed area north of Interstate 10. In the area of the project, Smith Creek contains an active low flow channel with adjacent active floodplain that is bordered with low terraces. The active low-flow channel is approximately 8-inches wide with a silty/sandy bed and no vegetation.

Evidence of flows were identified by benches and drift present in the project area. The adjacent active floodplain was on average 20-feet wide and the limits of which evidenced by a more pebbly substrate then the low flow channel, as well as ripples, older drift, presence of bed and bank, benches and limited pockets of early-stage vegetation. OHWM is approximately 6-inches and indicated by break in slope and changes in vegetative cover and sediment texture from active floodplain to low terrace. The low terrace borders the floodplain on the west with late-stage upland vegetation consisting mostly of California buckwheat that uniformly dominates the drainage area from the low terrace to the nearby hill tops. The outer limit of the low terrace is characterized by change in slope and a higher vegetative density of California buckwheat and marks the limit of potential CDFW jurisdiction.

Smith Creek likely flows for less than 3 months per year and is therefore does not have permanent flow and would not be considered USACE jurisdictional.

Highland Wash joins with Smith Creek at Westward Avenue. Smith Creek is tributary to San Gorgonio Creek, which is tributary to the Whitewater River. The Whitewater River is tributary to the Salton Sea located approximately 50 river miles to the southeast from the project area.

Pershing Creek is a wide ephemeral drainage containing riparian and riverine resources that flows from north to south and crosses perpendicular to the proposed project. It is located east of Smith Creek. Flows to Pershing Creek originate from north of Interstate 10. In the area of the project, Pershing Creek splits around an island approximately 0.24-acre in size of Riversidean alluvial fan sage scrub into two sets of active low flow channels with adjacent active floodplains. The Riversidean alluvial fan sage scrub is dominated by scale broom. The active low flow channels are approximately 10-inches wide in the project area with a fine sandy bed and no vegetation. Evidence of flows were identified by benches and ripples present in the project area. The active floodplain is on average 38-feet wide and bordered by short low terraces that are bordered by steep embankments that are roughly 20-feet high to the east and west of the creek. One mature eucalyptus tree (Eucalyptus species) on the far westerly bank is also within the project area. The active floodplain is evidenced by a more sandy/pebbly substrate then the low flow channel, as well as older drift, mud cracks, and earlystage vegetation of buckwheat and annual filarees (Erodium species). OHWM is approximately 10-inches and 1171
MSHCP Consistency Analysis
14 indicated by break in slope and changes in vegetative cover and sediment texture from active floodplain to low terrace. The low terrace borders the floodplain on the west with silty soil and 95% cover of late-stage upland vegetation consisting of California buckwheat that uniformly dominates the drainage area from the low terrace to the nearby hill tops. The outer limit of the low terrace on the east side of the creek is characterized by a change in slope and higher vegetative density of buckwheat and marks the limit of potential CDFW jurisdiction. The outer limit on the west side of the creek is characterized by a near-vertical incised channel bank.

Pershing Creek likely flows for less than 3 months per year and is therefore does not have permanent flow and would not be considered USACE jurisdictional. Pershing Creek merges with Smith Creek far downstream of the project limits.

Existing Culverts under Westward Avenue are riverine resources and potentially USACE jurisdictional waters because although they are confined and man-made, they convey flow from the three preceding drainages across Westward Avenue. There are a total of 6 culverts of varying diameters and lengths for a total footprint of approximately 0.02 acre within the project limits.

Highland Wash
• 18-inch diameter, 24 feet long
• 54-inch diameter, 27 feet long
• 54-inch diameter, 10 feet long Smith Creek
• 48-inch diameter, 35 feet long Pershing Creek
• 48-inch diameter, 45 feet long
• 48-inch diameter, 44 feet long
Table 2 lists the potentially jurisdictional features within the project footprint with additional details on each pursuant to USACE criteria. Figure 5 identifies all observed project site jurisdictional areas.

Flow from the project site drainages enters the MSHCP Conservation Area approximately 4.5 miles downstream in the San Gorgonio Pass Special Linkage Area.

The functions and values of the project site drainages and the surrounding upland loams include absorption and the gradual release of water into the downstream MSHCP Conservation Area. The drainages also provide sediment transport to downstream areas. The topography and vegetation in the project site drainages also provide cover and corridors for the shelter and movement of wildlife. The Project will include the construction of three sets of culverts to cross said creeks. The culverts are multi-cell reinforced concrete box (RCB) 1172
MSHCP Consistency Analysis
15 channels running under the proposed Sun Lakes Boulevard roadway extension.

Straight wing walls with concrete and riprap aprons will be constructed at the upstream end of each channel while vertical wing walls and concrete aprons will be provided at the downstream end of channels. Concrete ramps will be constructed at the south end of the channels to provide maintenance access.

Swales and trapezoidal channels will be provided to intercept stormwater runon from north of the Project and discharge it to the proposed channels. The culverts were designed so that sediment transport and wildlife movement functions and values will be retained.

In inland areas, most colonies are associated with large wetlands. There is no suitable habitat on the project site.
• black swift (Cypseloides niger): It nests in moist crevices or caves on sea cliffs above the surf, or on cliffs behind, or adjacent to, waterfalls in deep canyons. It forages widely over many habitats. Unlikely to occur on the project site, even as a foraging bird and there is no nesting habitat on the project site.
1176
MSHCP Consistency Analysis
19 • Cooper's hawk (Accipiter cooperii): This species is usually found in areas with dense tree stands or patchy woodland habitat. Recorded on the project site and there are trees suitable for nesting. Will be protected by “Protection of Nesting Birds” measures below.
• double-crested cormorant (Phalacrocorax auritus): Require lakes, rivers, reservoirs, estuaries, or the ocean. Possible only as a flyover species. There is no suitable breeding or foraging habitat on the project site. • downy woodpecker: Within southern California, the species generally nests in deciduous (often willow) woodlands, deciduous growth/oak woodlands, orchards, suburban plantings, and occasionally in conifers.

Lowland stream-bottoms constitute the main theaters of activity for this woodpecker. Available water may be a factor for the presence of the species. There is no suitable habitat on the project site. • Lincoln's sparrow (Melospiza lincolnii): Breeding in southern California occurs in wet montane meadows of corn lily, sedges, and low willows.

During the winter and spring and fall migration, the species requires thickets of shrubs or tall forbs interspersed with grassy areas, usually on damp ground or near water. It uses lowlands that are avoided during the breeding season. It likely occurs on the project site in winter and during spring and fall migration, but there is no breeding habitat. • MacGillivray's warbler (Geothlypis [Oporornis] tolmiei): Breeding pairs of MacGillivray's warbler typically are found in moist brushy areas within coniferous forests between 2,000-2,800 meters but may also be found in clear-cuts or mixed deciduous forests up to 3,000 meters. It may occur on the project site during migration, but there is no breeding habitat. • Nashville warbler (Leiothlypis [Vermivora] ruficapilla): This species most commonly breeds in montane chaparral habitats in southern California. It may occur on the project site during migration, but there is no breeding habitat on the project site.
• osprey (Pandion haliaetus): This species uses rivers, lakes, and reservoirs for foraging and rocky pinnacles, and large trees and snags in open forest for cover and nesting. There is no suitable habitat on the project site. • peregrine falcon (Falco peregrinus): Within southern California, peregrine falcons are primarily found at coastal estuaries and inland oases. It nests on cliffs, generally 200 to 300 feet in height that tend to dominate the surrounding landscape. It may forage on the project site, but there is no breeding habitat on the project site.
• purple martin (Progne subis): The species nests in cavities constructed by other bird species in tall, old trees near a body of water. It forages over riparian areas, forests, and woodland. It may be found virtually anywhere in aerial habitat during migration but is quite rare. It may occur on the project site during migration but breeding on the project site is not 1177
MSHCP Consistency Analysis
20 expected because of low population size and currently known breeding distribution.
• tree swallow (Tachycineta bicolor): The species forages primarily over and around ponds, marshes, rivers, lakes, and estuaries. Tree swallows nest almost exclusively in cavitycontaining trees or snags with cavities that are near, or preferably in, water. It may be found virtually anywhere in aerial habitat during migration and winter, so may occur while foraging or during migration. Breeding is not expected because there is no suitable habitat on the project site.
• tricolored blackbird (Agelaius tricolor): Breeding colonies require nearby water, a suitable nesting substrate, and open-range foraging habitat composed of grassland, woodland, or agricultural cropland. In winter, they often form single-species, and sometimes singlesex, flocks, but they also flock with other blackbird species. It is unlikely to forage on the project site, and there is no breeding habitat.
• white-faced ibis (Plegadis chihi): In southern California, extensive marshes are required for nesting. The species prefers shallow, grassy marshes and nests in dense, fresh emergent wetland. Migrant and wintering birds forage in shallow lacustrine waters, muddy ground of wet meadows, marshes, ponds, lakes, rivers, flooded fields, and estuaries. There is no project site habitat.
• white-tailed kite (Elanus leucurus): This species inhabits low elevation, open grasslands, savannah-like habitats, agricultural areas, wetlands, and oak woodlands. Riparian areas adjacent to open areas are used for nesting.

The project site could be used for foraging, but nesting habitat is marginal to absent. Will be protected by “Protection of Nesting Birds” measures below.
• Wilson's warbler (Cardellina [Wilsonia] pusilla): Breeding habitats for this species include montane meadows and low, dense willow thickets as well as other shrubs and scrub, often on steep slopes. During migration, these birds can be seen passing through many habitats. It may occur on the project site during migration, but there is no breeding habitat on the project site.
• yellow-breasted chat: In Southern California primarily found in dense, relatively wide riparian woodlands and thickets of willows, vine tangles, and dense brush with welldeveloped understories. Nesting areas are associated with streams, swampy ground, and the borders of small ponds.

The species is seldom seen in migration but may occur on the project site at that time. There is no breeding habitat on the project site. • yellow warbler: In Southern California, this species breeds in lowland and foothill riparian woodlands dominated by cottonwoods, alders, or willows and other small trees and shrubs. During migration, they occur in many 1178

5.1.4 Mitigation
The city intends to purchase land or preserve existing city land within the Whitewater Watershed, ideally along Smith Creek which would be placed in a conservation easement or have a deed restriction and protected in perpetuity with a non-wasting endowment. The land will be managed by a third-party land manager such as Western Riverside County Regional Conservation Authority (RCA), RLC or IERCD. . The purchased conservation land will contain similar habitat to the project site and provide similar or superior function and habitat value. Currently, the project site has relatively unvegetated, sandy bottom, riverine habitat. Any mitigation areas that contain riparian habitat would be considered superior habitat.
1179
MSHCP Consistency Analysis
22 Permanent impacts will be mitigated at a 3:1 (3 x 0.37 = 1.11 acres) ratio and temporary impacts will be mitigated at a 2:1 ratio (2 x 0.09 = 0.18 acres). The total mitigation acreage should equal or surpass 1.3 acres. The primary method of mitigation will be offsite conservation and enhancement of City owned property located along Smith Creek. The City will place at least 1.3 acres into a Conservation Easement with an approved third-party conservation holder such as Western Riverside County Regional Conservation Authority (RCA), Rivers and Lands Conservancy (RLC) or Inland Empire Resource Conservation District (IERCD). Additionally, the City has committed to participating in a regional solution of the sediment transport function of the Smith Creek watershed. The intended outcome of this regional solution is to bring the various stakeholders in this watershed together to work on a sediment management strategy to ensure sediment is transported efficiently and effectively to support ecological resources. The City’s commitment to this regional solution will serve as providing re rehabilitation mitigation for the overall impacts from this Project.

The project will also return temporary impact areas to their pre-existing contours and revegetate them with appropriate native species. Further details on how the project will achieve mitigation and equivalency and ensure the long-term conservation, sustainability, and maintenance of the functions and values of the riparian/riverine resource(s) will be addressed in the project’s Determination of Biological Equivalent or Superior Preservation (DBESP) report (WSP 2024e).

5.2 Vernal Pools
Vernal pools are seasonal wetlands that occur in depression areas. They have all three wetland indicators (soils, vegetation, and hydrology) during the wetter portion of the growing season but normally lack wetlands indicators of hydrology and/or vegetation during the drier portion of the growing season.

Obligate hydrophytes and facultative wetlands plant species are normally dominant during the wetter portion of the growing season, while upland species (annuals) may be dominant during the drier portion of the growing season.

5.2.1 Methods
During all 2020-2021 project site surveys, pooled areas were watched for vernal pool indicators. The entire project site was transected numerous times in all seasons.

5.2.2 Existing Conditions and Results
No pools meeting the vegetation parameters of a vernal pool were identified on the project site during any 2020 – 2021 project site surveys. 1180
MSHCP Consistency Analysis
23 5.2.3 Impacts
No vernal pools were detected, so there will be no impacts.

5.2.4 Mitigation
No vernal pools were detected, so no mitigation will be required.

5.3 Fairy Shrimp
Three species of fairy shrimp are covered by the MSHCP: Riverside fairy shrimp (Streptocephalus woottoni), Santa Rosa Plateau fairy shrimp (Linderiella santarosae), and vernal pool fairy shrimp (Branchinecta lynchi). The MSHCP states that suitable fairy shrimp habitat is “defined as vernal pools, stock ponds, ephemeral ponds, or other human-modified depressions.” Although these species are covered by the MSHCP, surveys are required for them in appropriate habitat.

5.3.1 Methods
Although no clay soils are mapped on the project site (Figure 6), non-vernal pool potential fairy shrimp habitat is present on the project site including stock ponds, ephemeral pools, road ruts, and human-made depressions. Such pools have been noted during various 2020 field surveys (Figure 7). A protocol-level fairy shrimp survey was conducted in the wet and dry seasons of 2020 – 2021 (WSP 2024a).

5.3.2 Existing Conditions and Results
Multiple pools or potential pools have been identified as fairy shrimp habitat or potential fairy shrimp habitat from review of historic aerial photography and during 2020 – 2021 surveys. Only the common versatile fairy shrimp was detected by 2020 – 2021 focused surveys, both in the wet and dry seasons.

5.3.3 Impacts
All fairy shrimp habitat and potential fairy shrimp habitat on the project site will be impacted.

5.3.4 Mitigation
No special status fairy shrimp were detected so no mitigation and avoidance are required.

MSHCP Consistency Analysis
24 5.4 Riparian Birds
The project site and adjacent vegetation is unsuitable habitat for state and federally listed riparian bird species such as the least Bell’s vireo (Vireo bellii pusillus), southwestern willow flycatcher (Empidonax traillii extimus), or western yellow-billed cuckoo (Coccyzus americanus occidentalis). Stands are too small and lack the necessary structure and density to support these species. No mitigation is required.
6 PROTECTION OF NARROW ENDEMIC PLANT SPECIES (SECTION 6.1.3) The project site is within the Narrow Endemic Plant Species Survey Area (NEPSSA) for Marvin’s onion (Allium marvinii) and many stemmed dudleya (Dudleya multicaulis) (Figure 8). Suitable habitat is present on site for those species. Therefore, focused surveys were conducted for these narrow endemic plants (NEPS).

6.1 Methods
The focused survey (WSP 2024b) was conducted on 26 and 27 May 2020 by WSP biologists Dale Hameister and Nathan T. Moorhatch. The survey was conducted during the appropriate time of year (blooming period) for the detection of the NEPSSA species and followed a period of above average rainfall for the 2019-2020 season. Areas of suitable habitat were surveyed utilizing transects which were adjusted based on topography and habitat coverage so that all potential NEPSSA habitat was surveyed.

6.2 Existing Conditions and Results
Marvin’s onion and many stemmed dudleya were not observed or otherwise detected during the focused survey. There are no historic records of these species on the project site, including during surveys conducted from 2002 - 2005. These plant species are considered absent from the project site.

6.3 Mitigation
Because no NEPS were detected, no impacts will occur. For these reasons, mitigation for NEPS is not required for the project.
7 ADDITIONAL SURVEY NEEDS AND PROCEDURES (SECTION 6.3.2)

7.1 Criteria Area Plant Species
The WRCRCA MSHCP Information Tool indicates the project site is not located within a CASSA for plants, therefore no actions are needed. 1182
MSHCP Consistency Analysis
25 7.2 Amphibians
The WRCRCA MSHCP Information Tool indicates that the project site is not within a MSHCP designated amphibian survey area, therefore no actions are needed.

7.3 Burrowing Owl
Burrowing owl habitat is present and the project site is within the MSHCP designated burrowing owl survey area (Figure 9) so focused surveys were conducted (WSP 2024c).

7.3.1 Methods
All burrowing owl surveys were conducted in accordance with protocol provided by the Riverside County Transportation and Land Management Agency (Environmental Programs Department “RCTLMA EPD” 2006a). Step I habitat assessment and Step II, Part A focused burrow surveys were conducted on 17 July 2020 by WSP senior biologist Nathan Moorhatch and biologist Alec Williams. The non-native grassland vegetation and portions of the various drainages with California ground squirrel and other manmade “burrow surrogates” on and immediately adjacent to the project site provide suitable habitat for burrowing owls. The site was surveyed on foot, mapping the locations of California ground squirrel burrows and/or manmade “burrow surrogates” that were suitable for burrowing owl use. Step II, Part B focused burrowing owl surveys were then conducted by Moorhatch or Williams on 24 & 31 July and 6 & 12 August 2020. Surveys were completed via pre-dawn/early morning pedestrian transects over 100% of those areas of the site identified in the burrow search as having burrows or structures capable of supporting burrowing owls. Binoculars were used to visually inspect potential perching locations (i.e., rocks, debris, dirt mounds) as well as the entrances to all onsite mammal burrows and debris providing potential shelter (i.e., piles of concrete slabs, cement drainpipes). Potential burrows were carefully examined for evidence of burrowing owl occupation (i.e., animal dung, feathers, whitewash, pellets, debris, etc.). Where buffer areas were not accessible, they were visually inspected using binoculars in accordance with protocol.

7.3.2 Existing Conditions and Results
Potential burrow sites were present, but no burrowing owls or their sign were detected. Therefore, no impacts to burrowing owls are anticipated at this time.

7.3.3 Impacts
Most, if not all, potential burrows on the project site will be permanently impacted by the project.
1183
MSHCP Consistency Analysis
26 7.3.4 Mitigation
Because no burrowing owls were detected, no impacts will occur. For this reason, mitigation and/or equivalency requirements relative to burrowing owls are not anticipated to be required for the project.

Note, however, that because the project site contains suitable, but currently unoccupied habitat, burrowing owls have the potential to colonize and occupy the project site at any time in the future. MSHCP guidelines require a one-visit pre-construction presence/absence surveys for burrowing owls within the survey area where suitable habitat is present, even where protocol level surveys were negative. Surveys will be conducted within 30 days prior to disturbance. If burrowing owls are found at that time, refer to the following guidelines below.

The project site is not located within a Criteria Area, so the following MSHCP guidelines apply:
• “If the site contains, or is part of, an area supporting less than 35-acres of suitable habitat or the survey reveals that the site and the surrounding area supports fewer than 3 pairs of burrowing owls, then the project site burrowing owls will be passively or actively relocated following accepted protocols.”
• “If the site (including adjacent areas) supports three or more pairs of burrowing owls, supports greater than 35 acres of suitable Habitat and is non-contiguous with MSHCP Conservation Area lands, at least 90 percent of the area with long-term conservation value and burrowing owl pairs will be conserved onsite.”
• ”RCTLMA EPD (2006b) states: “In the event owls are observed on the project site, please contact the EPD immediately to discuss potential mitigation measures such as passive or active relocation.” Further WRCRCA guidelines (2019b) include:
• Coordinate with WRCRCA and the CDFW on all evictions (passive or active relocation).
• Eviction may be acceptable if suitable conserved habitat and natural or artificial burrows are within 75–100 meters. Note that eviction during the nesting season is generally prohibited.
• If adjacent or nearby suitable habitat is not conserved, eviction may still be acceptable at the discretion of WRCRCA and/or CDFW.
• A Burrowing Owl Protection and Relocation Plan will be prepared and must be reviewed, approved, and coordinated with WRCRCA and Wildlife Agencies, including the state banding permit office and federal Migratory Bird Treaty Act office if active relocation is needed.
1184
MSHCP Consistency Analysis
27 Should burrowing owls be detected, an updated DBESP report will be prepared and mitigation will be achieved through the project following all MSHCP guidelines and the direction of the Environmental Programs Department, Western Riverside County Regional Conservation Authority, and/or the Wildlife Agencies.

7.4 Mammals
Los Angeles pocket mouse (LAPM) habitat is present and approximately 19.6- acres of the project site are within the MSHCP designated LAPM survey area (Figure 10), so focused surveys were conducted for the LAPM (WSP 2024d).

7.4.1 Methods
Trapping operations were conducted by WSP biologist John F. Green under the authority of CDFW Scientific Collecting Permit (SCP) #SC-190360007. A total of six grids of 25 traps each were placed (Grids A through F). One grid was placed in each drainage and the remaining three grids were placed in upland habitats. All grids were within the MSHCP-designated survey area for the Los Angeles pocket mouse.

To ensure that weather conditions were suitable to conduct the survey with minimal stress to captured animals, National Weather Service forecasts were monitored for the weather stations nearest the trapping areas. Trapping is not conducted unless five consecutive nights with temperatures above 50 degrees Fahrenheit are forecasted. At this time of year, no temperatures approached that threshold.

All traps were 12” long folding Sherman® live traps, modified by the manufacturer for the prevention of tail lacerations when trapping long-tailed animals (such as kangaroo rats). Traps were placed approximately ten meters apart and baited with white proso millet. Traps were opened at dusk daily, checked for captures at mid-night and dawn, and closed for the day following each dawn check. Trapping at each grid was conducted for five consecutive nights. Captured animals were identified and released at the point of capture.

Capture data and weather variables were recorded on standardized data forms. Weather variables were recorded with a handheld Kestrel anemometer.

7.4.2 Existing Conditions and Results
Within the LAPM survey area on the project site, potential habitat ranges from high quality in the drainages and from low-moderate quality in the uplands.

No LAPM were detected during the focused survey, however.

7.4.3 Impacts
LAPM appears to be absent from the project site. Therefore, impacts to LAPM will not occur as a result of project implementation.
1185
MSHCP Consistency Analysis
28 7.4.4 Mitigation
No LAPM are present, thus no impacts will occur and no mitigation for LAPM is required.

MSHCP Consistency Analysis
34 8.3 Protection of Nesting Birds
The MSHCP does not ever provide take for impacts to nesting birds (WRCRCA 2019b).

The project site contains suitable nesting habitat for several bird species discussed in this document as well as many additional bird species protected under state code (California Legislative Information 2021) and the federal Migratory Bird Treaty Act (MBTA) (USFWS 2021). These include most native bird species. Impacts to nesting birds, both direct and indirect, can be minimized or eliminated during project activities by conducting work outside of the breeding season. Although nesting can occur yearround in southern California for some species, the typical avian breeding season is from approximately February 1 through August 31, so it is recommended to schedule initial clearing and grubbing work between September 1 and January 31 to avoid nesting activity. The project site and adjacent areas should be examined by a qualified biologist prior to disturbance, especially where there could be any direct impacts. If active nests are found, the nests should be avoided and a “no disturbance” buffer zone established and observed until young have fledged. While there is no established protocol for nest avoidance and buffer zones, when consulted, the CDFW generally recommends avoidance buffers of 500 feet for raptors and listed species and 100–300 feet for other unlisted birds.
9 GUIDELINES PERTAINING TO THE URBAN/WILDLANDS INTERFACE (MSHCP SECTION 6.1.4)
Although the project site is not currently in or adjacent to the MSHCP Conservation Area, conservation is being proposed by an adjoining project immediately adjacent to proposed Sun Lakes Boulevard in Highland Wash, Smith Creek, Pershing Creek and in a buffer around them. Land conserved in those areas will become a part of the MSHCP Conservation Area. To preserve the integrity of areas described as existing or future parts of the MSHCP Conservation Area, the guidelines contained in the MSHCP Section 6.1.4 Urban Wildlands Interface Guidelines below should be implemented. The intent is to control the potential adverse effects of development on adjacent existing and future parts of the MSHCP Conservation Area.
 Measures will be incorporated to control the quantity and quality of runoff from the site entering the MSHCP Conservation Area, either directly or indirectly.

Standard best management practices (BMPs) from MSHCP Volume I, Appendix C will be included as applicable to ensure that siltation and erosion are minimized during construction, and also incorporated into the final design in order to ensure that future water quality is not degraded. In particular, measures shall be put in place to avoid the discharge of untreated surface runoff from developed and paved areas into existing natural drainage courses and/or the MSHCP Conservation Area. Any water quality or other drainage discharges must be reviewed by WRCRCA prior to conveyance into the MSHCP Conservation Area.  Land uses in proximity to the proposed conserved areas that use chemicals or generate bio-products, such as manure; that are potentially toxic; or that may 1192
MSHCP Consistency Analysis
35 adversely affect wildlife species, habitat, or water quality will 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.
 The siting and design of fencing will not impede wildlife movement. Design features may include, but not be limited to, jump-outs, pass-through gates and/or one-way gates. Fencing plans will include a commitment to routine maintenance.  Proposed land uses adjacent to the conserved areas will incorporate barriers, where appropriate, to minimize unauthorized public access, domestic animal predation, illegal trespass, or dumping. Such barriers may include native landscaping, rocks/boulders, fencing, walls, signage, and/or other appropriate mechanisms.
 Night lighting will be directed away from the conserved areas to protect species within the conserved areas from direct night lighting. Shielding shall be incorporated in project designs to ensure ambient lighting in the conserved areas is not increased.
 Proposed noise-generating land uses affecting the conserved areas will incorporate setbacks, berms, or walls to minimize the effects of noise on conserved areas pursuant to applicable rules, regulations, and guidelines related to land use noise standards.
 Invasive species will not be used in development or restoration plan activities, such as landscaping:

 Manufactured slopes will not extend into existing or planned conserved areas.  Weed abatement and fuel modification zones may not encroach into existing or planned Conservation Areas or avoidance areas.
10 BEST MANAGEMENT PRACTICES (MSHCP VOLUME I, APPENDIX C) The project will implement the following MSHCP Volume I, Appendix C Standard BMPs, as applicable:
 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.
 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, particularly during any activity that could directly or indirectly impact MSHCP resources.
 Water pollution and erosion control plans shall be developed and implemented in accordance with RWQCB requirements.
 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.
 The upstream and downstream limits of project 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.  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.  Projects that cannot be conducted without placing equipment or personnel in sensitive habitats should be timed to avoid the breeding season of riparian species identified in MSHCP Global Species Objective No. 7.  When stream flows must be diverted, the diversions shall be conducted using sandbags or other methods requiring minimal instream impacts. Silt fencing or other sediment trapping materials shall be installed at the downstream end of construction activity to minimize the transport of sediments offsite. Settling 1195
MSHCP Consistency Analysis
38 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.
 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 habitats. 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, US Fish and Wildlife Service, and CDFW, RWQCB and shall be cleaned up immediately and contaminated soils removed to approved disposal areas.
 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.
 The removal of native vegetation shall be avoided and minimized to the maximum extent practicable. Temporary impacts shall be returned to preexisting contours and revegetated with appropriate native species.  Exotic species that prey upon or displace target species of concern should be permanently removed from the site to the extent feasible.  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).  Construction employees shall strictly limit their activities, vehicles, equipment, and construction materials to the 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.
 The Permittee shall have the right to access and inspect the project site including any restoration/enhancement area for compliance with project approval conditions including these BMPs (“The Permittee in this context is a signatory agency to the MSHCP).

Sun Lakes Boulevard Realignment Project
Los Angeles Pocket Mouse Focused Survey
May 2024

1.0 INTRODUCTION
At the request of the Albert A. Webb and Associates (Webb), WSP USA Inc. (WSP) conducted a focused survey for the Los Angeles pocket mouse (Perognathus longimembris brevinasus) on the Sun Lakes Boulevard Realignment Project site (project).

The project is in the city of Banning, Riverside County, California (Figure 1) and includes the extension of Sun Lakes Boulevard eastward from its current termination point at Highland Home Road to the anticipated connection at West Lincoln Street.

Portions of the project site lie within the Western Riverside County Multiple-Species Habitat Conservation Area (MSHCP) survey area for the Los Angeles pocket mouse and potential habitat for the species is present.

2.0 PROJECT BACKGROUND/SITE DESCRIPTION
The project is generally located south of Interstate 10, west of Sunset Avenue and east of Highland Home Road between the terminus of Sun Lakes Boulevard on the west and the terminus of paved Westward Avenue on the east. It can be found in Section 7 of Township 3 South, Range 1 East of the Beaumont, California, United States Geological Survey (1978)

7.5-minute topographic quadrangle map (Figure 2). The elevation of the project site ranges from approximately 2,400 to 2,500 feet above sea level. The geographic coordinates near the middle of the site are 33.5512.85° North latitude and -116.5516.29° West longitude. Vegetation communities on site consist primarily of grassland and scrubs.

The proposed project is a transportation project including construction of a new section of Sun Lakes Boulevard from Highland Home Road to Sunset Avenue (Figure 3) and intersection improvements within the City of Banning’s existing road right-of-way (ROW).

This report has been updated due to a change is the outline of the proposed impacts and to update all related figures. The project is approximately 5,400 linear feet (1.02 mile) and 110-feet wide, encompassing approximately 19.4 acres of direct footprint and another 9.1 acres of temporary construction disturbance area. Project staging and stockpiling will occur within the City’s ROW. Currently, Westward Avenue is a straight east-west unpaved dirt road between Highland Home Road and Sunset Avenue. The project crosses over three creeks, from west to east: Highland Wash, Smith Creek, and Pershing Creek. The project will include the construction of three sets of culverts to cross said creeks.

3.0 BACKGROUND ON THE LOS ANGELESPOCKET MOUSE
The Los Angeles pocket mouse is a small rodent of the inland valleys and foothills of southern California, one of eight subspecies of the widespread little pocket mouse (P. longimembris) and is not well-studied. It is nocturnal, spending daylight hours in underground burrows or under surface debris and is essentially undetectable except by trapping surveys. It is one of few rodents to enter torpor during winter, a dormant state in which the metabolism is greatly lowered in order to cope with cold and the resulting lack of food.

Los Angeles Pocket Mouse Focused Survey
May 2024

The Los Angeles pocket mouse is associated with annual grassland, coastal sage scrub, desert scrub, and alluvial sage scrub at lower elevations and usually in sandy soils, but there is much left to learn of its specific habitat requirements. Small mammal biologists in western Riverside County have often found the highest concentrations of this subspecies along or near prominent drainages. Its historic range extended as far west as Burbank and San Fernando in Los Angeles County. Urbanization and agriculture have eliminated much of its historic habitat (Williams 1986), resulting in a current estimated range bordered on the west by Rancho Cucamonga in San Bernardino County, on the east by the San Gorgonio Pass in Riverside County, and extending south to the vicinity of Aguanga and Oak Grove in San Diego County (Patten et al. 1998).

This subspecies is not federally, or state listed as threatened or endangered. It is, however, designated a species of special concern by the California Department of Fish and Wildlife (CDFW) (2020) and has been assigned a state rank of S1S2 meaning that the subspecies is considered to be between “critically imperiled” and “imperiled” and “at very high risk of extinction due to extreme rarity” (between 5 or fewer and < than 20 populations), subject to “very steep” to “steep declines, or other factors.”
Portions of the project site lie within the Western Riverside County Multiple-Species Habitat Conservation Area (MSHCP) survey area for the Los Angeles pocket mouse (Figure 3) and potential habitat for the species is present. Under the MSHCP, surveys for the Los Angeles pocket mouse are required in appropriate habitat within the designated survey areas in order to achieve coverage for the species.

A total of six grids of 25 traps each were placed (Grids A through F) See Figure 3 and photos below. One grid was placed in each drainage and the remaining three grids were placed in upland habitats.

All grids were within the MSHCP-designated survey area for the Los Angeles pocket mouse.

Trapping operations were conducted by WSP biologist John F. Green under the authority of CDFW Scientific Collecting Permit (SCP) #SC-190360007. Because the federally listed as endangered, state listed as threatened Stephens’ kangaroo rat (Dipodomys stephensi) is known to have occurred onsite, Stephens’ kangaroo rat permit holder Phil Brylski was also present for all trapping. Brylski worked under authority of federal permit TE14855-2, a CDFW MOU, and authorizations attached to CDFW SCP 314.

To ensure that weather conditions were suitable to conduct the survey with minimal stress to captured animals, National Weather Service forecasts were monitored for the weather stations nearest the trapping areas. Trapping is not conducted unless five consecutive nights with temperatures above 50 degrees Fahrenheit are forecasted. At this time of year, no temperatures approached that threshold. Traps were set on consecutive nights from September 13-18, 2020.

All traps were 12” long folding Sherman® live traps, modified by the manufacturer for the prevention of tail lacerations when trapping long-tailed animals (such as kangaroo rats).

Traps were placed approximately ten meters apart and baited with white proso millet.

Traps were opened at dusk daily, checked for captures at dawn, and closed for the day following each dawn check. To comply with Stephens’ kangaroo rat trapping guidelines traps were also checked each night. Trapping at each grid was conducted for five consecutive nights. Captured animals were identified and released at the point of capture.

Capture data and weather variables were recorded on standardized data forms. The Collector app on an iPhone 8 was used to place and record grids and points for specialstatus species. Weather variables were recorded with a handheld Kestrel anemometer.

Table 1 summarizes the number of traps, weather variables, and moon phases during the survey.

5.0 RESULTS
Overall, 583 mammal captures were made of seven species for a trapping success rate of

77.7%. Although known to occur in the area, no Los Angeles pocket mice were captured.

Two other specials tatus species was captured: the northwestern San Diego pocket mouse (Chaetodipus fallax fallax) and the Bryant’s Woodrat (Neotoma bryanti intermedia) which was formerly known as San Diego desert woodrat. Both are CDFW species of special concern, and both are covered under the MSHCP.

Table 2 presents the complete results of the trapping survey.

Two other special-status species were also incidentally detected during the trapping effort: loggerhead shrike (Lanius ludovicianus) and California horned lark (Eremophila alpestris actia). The status of these animals will be discussed in other supporting project documents.
