PREPARED BY: City Clerk's Office
MEETING DATE: March 21, 2022
SUBJECT:

Remote Teleconferenced City Council and Commission Meetings – Reauthorization RECOMMENDATION:

Adopt a Resolution to reauthorize remote teleconferenced City Council and Board and Commission meetings for 30 days, through April 22, 2022, as allowed by Assembly Bill 361 amending the Brown Act, based upon the Governor’s emergency proclamation and findings that meeting in person would present imminent risks to the health or safety of attendees.

BACKGROUND:

At its October 18, 2021, City Council meeting, the Council adopted Resolution No. 100 (2021) authorizing continued remote meetings of the Council and its subordinate legislative bodies due to the imminent risk to the health and safety of attendees due to possible transmission of COVID-19 and the recent spread of variants. The resolution became effective October 18, 2021 through November 17, 2021, or until the City Council adopts a subsequent resolution. AB 361 requires confirming the emergency circumstances 30 days after the first teleconference meeting and every 30 days thereafter. At the October 18 meeting, the Council accepted staff’s recommendation to pass a resolution at every meeting to ensure there is no gap in the effectiveness of authorizing resolutions. The action being requested at this March 21st meeting is to adopt a resolution reauthorizing remote teleconferenced Council and Commission meetings per the requirements of Assembly Bill 361.

It was noted in the original resolution that current health orders require masking in all indoor facilities due to health and safety concerns. While San Mateo County Health Order No. c19-12 (which required masking in workplaces and public settings) was rescinded on February 16, 2022, the Delta and Omicron variants are highly transmissible in indoor settings and requires multi-component prevention strategies to reduce their spread. Thus, as of February 16, 2022, the California Department of Public Health still requires masking for unvaccinated people (and recommends the practice for all) in indoor public settings as well as in state and local government offices that serve the public. Returning to meeting in the Council Chambers or smaller conference rooms means being in an enclosed space for meetings that commonly last for one to five hours and would seem to create additional exposure for participants to a possible transmission of the virus. This health advice is still in place.

BUDGET IMPACT:

There is no budget impact for taking this action as all software and hardware needs to meet remotely have already been purchased and are in use.

ENVIRONMENTAL DETERMINATION:

Adoption of this resolution authorizing remote teleconferenced meetings of the City Council and City Boards and Commission is not a project subject to CEQA, because it is an organizational or administrative activity that will not result in direct or indirect physical changes in the environment. (CEQA Guidelines Section 15378(b)(5).) 11 of 662

This requested has been noted and an update will be scheduled for spring of 2023, 12 months after the ADU ordinance has been in effect.

MEETING DATE: March 21, 2022
SUBJECT:

Ordinance Introduction – Disposable Food Service Ware Code Amendment RECOMMENDATION:

Introduce an Ordinance to amend the San Mateo Municipal Code Chapter 5.89 "Disposable Food Service Ware" to align with the new State laws.

BACKGROUND:

Many disposable food service ware items, such as cups, utensils, straws, and clamshells are made from plastic and used for mere minutes before becoming waste that remains in our landfills for hundreds of years. These items are also a major contributor to street litter and pollution in our waterways. In 2020, the County of San Mateo developed a model ordinance that requires food facilities distribute disposable food service ware items that are compostable and provide disposable accessories (e.g., straws, utensils, condiment packets) upon request. In February 2021, the City of San Mateo adopted Ordinance No. 2021-3 modeled off the County’s ordinance. In August 2021, the City entered into a Memorandum of Understanding (MOU) with the County to enforce the ordinance beginning October 1, 2022. This delayed enforcement date allows food facilities to use up existing food service ware inventory and evaluate compliant products for future use.

Since the adoption of the City’s Disposable Food Service Ware Ordinance, the State of California adopted Assembly Bills 1276 and 1200 addressing disposables at food facilities. The new legislation has a similar intent to the City’s adopted ordinance but there are a few nuanced differences. This report provides an overview of the two new laws and includes a draft ordinance for Council consideration. The draft ordinance was revised under County guidance and includes changes to align with the AB 1276 and AB 1200.

New Laws Impacting the City’s Disposable Food Service Ware Ordinance AB 1276: Single-use foodware accessories and standard condiments AB 1276 requires food facilities only distribute disposable accessories such as utensils, stirrers, splash sticks, and condiment packets upon request by the customer, with an exception for drive-throughs. AB 1276 also prohibits the use of open bins or containers to distribute accessories but allows the use of refillable dispensers that dispense accessories one item at a time and refillable bulk condiment dispensers. The law directs local governments to authorize an enforcement agency to enforce these statutes by June 1, 2022 but does not provide a specific implementation date.

AB 1200: Plant-based food packaging
AB 1200 prohibits the sale or distribution of all single-use fiber-based food service ware with intentionally added perfluoroalkyl and polyfluoroalkyl substances, a class of hazardous chemicals known as PFAS. PFAS are often used to make fiber-based food ware water and grease resistant. AB 1200 prohibits the sale or distribution of single-use food ware comprised of paper or other plant-based natural fiber that contains intentionally added PFAS beginning January 1, 2023. 26 of 662

CITY OF SAN MATEO

Ordinance Amendment
Currently, the City’s adopted ordinance requires the distribution of disposable accessories upon request by the customer at all food facilities and allows the use of open bins and containers for the distribution of accessories. The draft ordinance is updated to prohibit the use of open bins and containers for disposable accessories. Furthermore, the draft ordinance explicitly allows for the use of dispensers that dispense accessories one at a time and the use of self-serve, refillable bulk condiment dispensers to distribute condiments. The draft ordinance also makes drive-throughs exempt from the distribution requirements for accessories.

Currently, the City’s ordinance restricts the use of PFAS in specific types of food service ware. To align with AB 1200, staff recommends adding language for the City’s PFAS requirement to end on December 31, 2022 before AB 1200 goes into effect on January 1, 2023. AB 1200 will require all disposable food service ware to not contain intentionally added PFAS.

A clean copy of the draft ordinance is provided as Attachment 1, and a tracked changes version that reflects the changes from the City’s current ordinance is included as Attachment 2. The majority of the changes were made to Municipal Code Section 5.89.010, “Definitions,” and Section 5.89.020, “Distribution of Disposable Food Service Ware Accessories,” to align with AB 1276. To align with AB 1200, Municipal Code Section 5.89.030, “Standards and Required Use of Disposable Food Service Ware,” was modified. In addition to these changes, the County used this opportunity to recommend minor changes to some definitions and to clarify and simplify language in the ordinance.

Next Steps
Due to the State’s adoption of these new bills, County staff changed the enforcement date of the County ordinance from March 25, 2022, to October 1, 2022. County staff are also recommending that other cities with the same March enforcement date delay enforcement to align with the County’s October 1, 2022, enforcement date. The City of San Mateo already has an October 1, 2022, enforcement date and as a result will now align with the timeline of the County and other jurisdictions that have adopted the ordinance. In February 2021, staff had recommended having a delayed enforcement date in effort to benefit from any lessons learned in the initial roll out of the ordinance in other jurisdictions. Staff now recommends keeping the October 1, 2022, enforcement date to align with the County’s unified approach.

Beginning this summer, the County plans on the following outreach and engagement activities to prepare food facilities for the October 1 enforcement date:
The County will send mailers alerting food facilities of the upcoming enforcement start date and available resources and technical support.
The County will host a workshop (virtual or in-person TBD) reviewing ordinance requirements and a “meet-and- greet” with vendors that sell compliant disposable food ware. The County will make phone calls to impacted food facilities to inform them of the ordinance, upcoming enforcement start date, and workshop.
The County will develop social media posts and share social media content with cities to repost. The County will also share ordinance information via digital ads and public service announcements on the radio. The County will share content with relevant community-based groups (e.g., NGOs, chambers, business districts, etc.) within each jurisdiction and waste haulers for them to push out to their networks. The County will staff a hotline for food facilities to call in with questions.

Staff recommends City Council adopt the draft ordinance amending San Mateo Municipal Code Chapter 5.89 “Disposable Food Service Ware,” to align with the newly adopted State bills.

BUDGET IMPACT:

There is no budget impact as a result of adopting the ordinance amendment. The City has an MOU with the County of San Mateo to lead technical support, outreach, education, and enforcement activities for the Disposable Food Service Ware Ordinance. The County’s support will minimize the impact on City resources for implementation of the ordinance. City staff will provide some implementation support to supplement education and compliance of the ordinance.

ENVIRONMENTAL DETERMINATION:

This Ordinance is exempt from the environmental review requirements of CEQA pursuant to, section 15061(b)(3), of Title 14 of the California Code of Regulations because it can be seen with certainty that there is no possibility that the provisions contained herein may have a significant effect on the environment. Further, the Ordinance is also exempt from the requirements of CEQA pursuant to CEQA Guidelines Sections 15307 and 15308 of Title 14 of the California Code of Regulations as it is an action taken by a regulatory agency to assure the maintenance, restoration, enhancement of natural resources, or protection of the environment.

NOTICE PROVIDED
All meeting noticing requirements were met. The City will send out a mailer to food facilities following the adoption of the amended ordinance. The County will lead engagement and outreach efforts with food facilities this summer in preparation for the October 1, 2022 ordinance enforcement date.

FROM: Drew Corbett, City Manager
PREPARED BY: Public Works Department
MEETING DATE: March 21, 2022
SUBJECT:

Poplar at Golf Course Trash Capture Project – Initial Study/Mitigated Negative Declaration RECOMMENDATION:

Adopt a Resolution to adopt the Initial Study/Mitigated Negative Declaration for the Poplar at Golf Course Trash Capture Project.

BACKGROUND:

The Poplar at Golf Course Trash Capture Project (Project) is part of the City’s plan to achieve compliance with the San Francisco Bay Regional Water Quality Control Board’s (RWQCB) Municipal Regional Stormwater Permit’s trash capture requirements. The Project will provide approximately 12% of additional trash capture reduction and allow the City to remain compliant with the permit requirements. The Project consists of the installation of four full-capture screen devices within an existing concrete-lined storm drainage channel adjacent to the Poplar Creek Golf Course.

On January 18, 2022, WRA, the City’s environmental consultant, completed the Initial Study/Mitigated Negative Declaration (IS/MND) documents for the Project. The IS/MND was circulated for public review and comment on January 25, 2022 for a period of 30 days ending on February 23, 2022. This was performed in accordance with the California Environmental Quality Act (CEQA) requirements. No comments were received for the Project during the public comment period.

Given the importance of the Project to meeting the City’s trash capture requirements and that any identified environmental impacts associated with the Project can be mitigated to less than significant levels, staff recommends that City Council adopt the resolution adopting the IS/MND for the Project.

BUDGET IMPACT:

Sufficient funds are available in the Poplar at Golf Course Trash Capture Project.

ENVIRONMENTAL DETERMINATION:

Council adoption of the IS/MND will fulfill the CEQA requirements for this project. The IS/MND is included as Attachment 2.

NOTICE PROVIDED
A Notice of Availability (NOA) of the IS/MND was published in the San Mateo Daily Journal on January 25, 2022. Thirty (30) days were given to receive the public’s comments in accordance with CEQA provisions.

Poplar at Golf Course Trash Capture Project Mitigated Negative Declaration City of San Mateo January March 2022 2 FINDING
The Director of Public Works finds that the project described above will not have a significant effect on the environment. Prior to the release of this the draft Mitigated Negative Declaration (MND), the project applicant (City of San Mateo) has made/agrees to make project revisions that clearly mitigate the potentially significant environmental effects identified in the attached Initial Study to a less-than-significant level.

MITIGATION MEASURES INCLUDED IN THE PROPOSED TO REDUCE POTENTIALLY

SIGNIFICANT EFFECTS TO A LESS-THAN-SIGNIFICANT LEVEL
A. AESTHETICS – The project will not have a significant impact on this resource; therefore, no mitigation is required.

B. AGRICULTURE AND FOREST RESOURCES – The project will not have a significant impact on this resource; therefore, no mitigation is required.

C. AIR QUALITY –
Impact AIR -1: Construction activities could produce fugitive dust fugitive dust (PM 10 and PM2.5) during ground disturbance, which the Bay Area is currently classified as nonattainment.

Mitigation Measures AIR -1: The Bay Area Air Quality Management District (BAAQMD) recommends basic construction measures to ensure minimal impacts on regional air quality.

The contractor would be responsible for implementing the following basic measures during construction:
• All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas) will be watered two (2) times per day.
• All haul trucks transporting soil, sand, or other loose material off-site will be covered. • All visible mud or dirt track-out onto adjacent public roads will be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited.
• Idling times will be minimized either by shutting equipment off when not in use or reducing the maximum idling time to five (5) minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations).
• Clear signage will be provided for construction workers at all access points. • All construction equipment will be maintained and properly tuned in accordance with manufacturer specifications, and all equipment will be checked by a certified visible emissions evaluator.

Poplar at Golf Course Trash Capture Project Mitigated Negative Declaration City of San Mateo January March 2022 3 • A publicly visible sign with the telephone number and person to contact at the lead agency regarding any dust complaints will be posted in or near the project site. The contact person will respond to complaints and take corrective action within 48 hours.

BAAQMD ‘s phone number will also be vi sible to ensure compliance with applicable regulations.

D. BIOLOGICAL RESOURCES –
Impact BIO-1: Construction activities and vegetation removal associated with the project could result in the destruction or abandonment of nests of non-status bird species protected under the MBTA, CFGC, and CEQA.

Mitigation Measures BIO -1: To the extent feasible, project-related activities should be avoided during the nesting bird season, generally defined as February 1 through August 31.

If project work must occur during the nesting bird season, pre-construction nesting bird surveys must b e conducted within 14 days of ground disturbance to avoid disturbance to active nests, eggs, and/or young of nesting birds. These surveys would determine the presence or absence of active nests that may be affected by project activities. It is also recommended that any trees and shrubs in or adjacent to the project site that are proposed for removal and that could be used as avian nesting sites be removed during the non-nesting season (September 1 through January 31).

E. CULTURAL RESOURCES –
Impact CULT-1: Implementation of the project could result in impacts to buried prehistoric or historical archaeological deposit.

Mitigation Measure CULT -1: If previously unidentified historic resources are encountered during project implementation, the contractor shall avoid altering the materials and their stratigraphic context. A qualified professional archaeologist shall be contacted to evaluate the situation. Project personnel should not collect cultural resources. Historic resources include stone or abode foundations or walls; structures and remains with square nails; and refuse deposits or bottle dumps, often located in old wells or privies. The City or its contractor shall comply with California Health and Safety Code Section 7050.5 and California Public Resources Code Sections 5097.5, 5097.9 et seq., regarding the discovery and disturbance of cultural materials, should any be discovered during project construction.

Impact CULT -2: Project construction activities could result in impacts to previous undiscovered human remains.

Mitigation Measure CULT -2: If human remains are discovered during excavation and/or grading of the site, all activity within a 50-foot radius of the find shall be stopped. The San Mateo County Coroner shall be notified and make a determination as to whether the remains are of Native American origin or whether an investigation into the cause of death is required.

If the remains are determined to be Native American, the Coroner will notify the Native American Heritage Commission (NAHC) immediately. Onc e the NAHC identifies the most DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 48 of 662
Poplar at Golf Course Trash Capture Project Mitigated Negative Declaration City of San Mateo January March 2022 4 likely descendants, the descendants will make recommendations regarding proper burial, which will be implemented in accordance with Section 15064.5(e) of the CEQA Guidelines.

F. ENERGY – The project will not have a significant impact on this resource; therefore, no mitigation is required.

G. GEOLOGY AND SOILS – The project will not have a significant impact on this resource; therefore, no mitigation is required.

H. GREENHOUSE GAS EMISSIONS – The project will not have a significant impact on this resource; therefore, no mitigation is required.

I. HAZARDS AND HAZARDOUS MATERIALS – The project will not have a significant impact on this resource; therefore, no mitigation is required.

J. HYDROLOGY AND WATER QUALITY –
Impact HYDR-1: Project construction during in -channel work would have the potential to impact water quality.

Mitigation Measure HYDR -1: The City shall incorporate the following practices into the construction documents to be implemented by the project contractor:
• During channel dewatering, all water pumped out of the work area would be collected in a settling tank and undergo turbidity testing before being discharged back in the channel. The settling tank would be up to 10,000 gallons in size depending on the results of water flow testing at the time of construction and would be located in the designated staging area.
• Equipment fueling and maintenance would occur off-site. • Fiber rolls would be installed between the staging area and the channel to prevent runoff of sediment into the channel. Rolls will be inspected and maintained on a weekly basis.
• Hazardous waste spill prevention and stockpiling methods will be implemented according to California Stormwater Quality Association (CASQA) best management practices.

K. LAND USE AND PLANNING – The project will not have a significant impact on this resource; therefore, no mitigation is required.

L. MINERAL RESOURCES – The project will not have a significant impact on this resource; therefore, no mitigation is required.

M. NOISE –
Impact N OI-1: Construction noise could exceed the City of San Mateo Municipal Code standard.

Poplar at Golf Course Trash Capture Project Mitigated Negative Declaration City of San Mateo January March 2022 5 Mitigation Measure NOI-1: The City shall incorporate the following practices into the construction documents to be implemented by the project contractor:
• Construction hours shall be limited to 7:00 A.M. to 5:00 P.M., Monday through Friday only.
• Notify businesses, residences, and noise-sensitive land uses adjacent to construction sites of the construction schedule in writing. Designate the City’s construction manager as responsible for responding to any local complaints about construction noise. The construction manager shall determine the cause of the noise complaints (for example starting too early, or a bad muffler) and institute reasonable meas ures to correct the problem. Conspicuously post a telephone number for the construction manager at the construction site.
• Maximize the physical separation between noise generators and noise receptors.

Such separation includes, but is not limited to, the following measures:
 Use heavy-duty mufflers for stationary equipment and barriers around particularly noisy areas of the site or around the entire site;
 Where feasible, use shields, impervious fences, or other physical sound barriers to inhibit transmission of noise to sensitive receptors;  Locate stationary equipment to minimize noise impacts on the community; and  Minimize backing movements of equipment.
• Use quiet construction equipment whenever possible.
• Impact equipment (e.g., jack hammers and pavement breakers) shall be hydraulically or electrically powered wherever possible to avoid noise associated with compressed air exhaust from pneumatically -powered tools. Compressed air exhaust silencers shall be used on other equipment. Other quieter procedures, such as drilling rather than using impact equipment, shall be used whenever feasible. • Prohibit unnecessary idling of internal combustion engines N. POPULATION AND HOUSING – The project will not have a significant impact on this resource; therefore, no mitigation is required.

O. PUBLIC SERVICES – The project will not have a significant impact on this resource; therefore, no mitigation is required.

P. RECREATION – The project will not have a significant impact on this resource; therefore, no mitigation is required.

Q. TRANSPORTATION – The project will not have a significant impact on this resource; therefore, no mitigation is required.

R. TRIBAL CULTURAL RESOURCES – Mitigation Measures CULT-1 and CULT-2 of the project would allow for appropriate treatment of tribal cultural resources and human remains should they be discovered at the site. With implementation of these mitigation measures, the City can preserve and protect unknown tribal cultural resources discovered at the site.

Poplar at Golf Course Trash Capture Project Mitigated Negative Declaration City of San Mateo January March 2022 6 S. UTILITIES AND SERVICE SYSTEMS – The project will not have a significant impact on this resource; therefore, no mitigation is required.

T. WILDFIRE – The project will not be impacted by wildfire or will not exacerbate wildfire conditions in the area; therefore, no mitigation is required.

U. MANDATORY FINDINGS OF SIGNIFICANCE – With the implementation of the mitigation measures identified above, and the conditions of approval identified in the Initial Study, the project would not degrade the quality of the environment, substantially affect the biological resources, or eliminate important examples of California history or prehistory. The mitigation measures and standard permit conditions would also ensure that the project’s contribution to cumulative impacts would not be cumulatively considerable, and the project would not cause substantial adverse effects on human beings, either directly or indirectly.

3. Contact Person and Phone Number: Elton Yee
Tel: (650) 522-7320
Email: [email protected]

4. Project Location: Immediately north of the intersection of East Poplar Avenue and North Bayshore Boulevard and adjacent to
the Poplar Creek Golf Course within Poplar Creek in
the City of San Mateo, San Mateo County, C alifornia
(see Figures 1 and 2)

5. Surrounding Land Uses and Setting:

The proposed project is located at Assessor’s Parcel Number (APN) 029-350-020, north of the intersection of East Poplar Avenue and North Bayshore Boulevard and within Poplar Creek on the premises of the Poplar Creek Golf Course property at 1700 Coyote Point Drive in San Mateo, San Mateo County (Figure 1). The project proposes to install a full trash capture device within Poplar Creek (Site 1) and to provide native vegetation enhancement along Poplar Creek (Site 2). Both Sites 1 and 2 together will collectively be referred to as the project site. The project footprint is on Poplar Golf Course land and does not encroach on other properties.

The proposed project is located within Poplar Creek which is an intermittent and concrete-lined channel From Site 1, Poplar Creek continues in a northeasterly direction for approximately 3,000 feet past Site 2, at which time the channel becomes unlined and begins to flow in the southeasterly direction. This earthen channel conveys flow for approximately 700 feet before discharging into the open forebay of the Poplar Pump Station. Flow from the forebay enters the pump station intake and is discharged through the earthen flood control levee into San Francisco Bay (Figure 2).

The project site is bounded to the west and south by the City of San Mateo (City) right-of-way (ROW) consisting of East Poplar Avenue and North Bayshore Boulevar d. Site 1 is across from residential housing on the opposite side of East Poplar Avenue and North Bayshore Boulevard. A Pacific Gas & Electric (PG&E) Electrical Substation operates on the southern side of East Poplar Avenue across from Site 2. The sites can be accessed from East Poplar Avenue and through existing golf course infrastructure.

The proposed project falls within the Shoreline Park Specific Plan Zone for the City. The zoning district designated for the project site is S-Shoreline. The General Plan land use designation for the site is Parks/Open Space, and the land use designations in the project vicinity include Parks/Open DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 60 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 5 6. Existing System:

Poplar Creek is a concrete-lined channel that flows intermittently that passes though the City of San Mateo. With the exception of the Poplar Creek Golf Course, the surrounding area is composed of largely impermeable structures including buildings, maintenance lots, and streets. Mixed woodland vegetation is located above top of bank (TOB) along the southeast side of the channel. The northeast side of the channel is composed of a ruderal grassland community (Figure 3).

Poplar Creek is a section of the City’s storm drain system. Currently, there is no device within the channel to facilitate the removal of trash or unwanted debris that enters the system before it gets discharged into the San Francisco Bay.

Under Provision C.10 of the City’s Municipal Regional Stormwater National Pollutant Discharge Elimination System (NPDES) permit, the City of San Mateo is required to reduce trash loads from municipal separate storm sewer systems (MS4s) by 100 percent by July 1, 2025. The trash capture device proposed by this project would be used to reduce trash loads from approximately 333 acres of San Mateo’s upstream storm drain system, approximately 3.3 acres of the California Department of Transportation’s (Caltrans ’) significant trash generating area (STGA), and approximately

15.9 acres of Caltrans right-of-way (ROW).

7. Project Design Alternatives:

Trash Capture Device Placement Considerations
Two (2) site locations for the proposed trash capture device location were evaluated in the project design phase. A Hydraulic Impact Study was conducted to determine which placement would have the least detrimental effect to overall stormwater flow throughout the Poplar Creek System (Appendix A). Site 1 was chosen as the location for the proposed project by the Board of Supervisors.

Stream Enhancement Considerations
Three (3) site locations were analyzed as potential stream enhancement locations. Stream Enhancement Site 2 was selected as the proposed location due to its proximity to Poplar Creek, City ownership, ease of irrigation, and distance from golfer traffic along the Poplar Creek course. Stream Enhancement Site 2 also had the largest available area for enhancement when compared to other proposed areas.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 7 8. Project Description:

Trash Capture Device Installation and Operation
The proposed project would install a trash capture device composed of four (4) Roscoe Moss Storm Flo® Trash Screen Linear Radial Gross Solids Removal Devices, which constitutes a Full Capture System device that is approved by the State Water Resources Control Board (SWRCB). Each of the four (4) screens would be made of stainless steel and would be approximately 18 inches in diameter and 25 feet long. The four (4) screens would be prefabricated and would be installed at two-foot intervals along a three-foot high by one-foot-wide concrete weir wall and would be secured with stainless steel anchor plates.

Prior to construction, two (2) temporary cofferdams would be installed within the channel. Each of the cofferdams would be constructed using gravel bags or similar material and w ould be approximately 10 feet wide and 3.5 feet tall. A temporary 18-inch diameter pipe would be used to bypass the creeks flows while the cofferdams are in place. An existing approximately 10-foot by 30-foot section of the concrete-lined channel would then be removed through saw -cutting and demolished by an excavator stationed outside/above the creek. A reinforced concrete weir would be formed and poured along with the sides and bottom of the channel reconstructed. The trash capture screen will be secured to the new concrete weir. Wooden forms would be used to reconstruct both the new concrete weir and the replacement of the channel sides and bottom. The concrete would be allowed to set for at least three days before the wooden forms would be removed. A visual depiction of the design details can be viewed in the Poplar at Golf Course Trash Capture Device 75 percent project plans (Appendix B).

Once installed, each screen would capture solids as water passes through. The trash capture device would be visually inspected monthly during the rainy season (October 15 – April 15). Trash would be removed two (2) to three (3) times per year including at the beginning of the rainy season and whenever trash fills more than 50 percent of the device. Trash removal would involve a maintenance staff person to open the hatches on top of each of the four (4) trash capture devices, followed by one (1) to two (2) maintenance staff members to guide a vacuum truck nozzle to the hatch opening.

The vacuum truck would be located in the permanent staging area created by the proposed project on the channel’s northwestern bank. Hand equipment (e.g., rakes ad shovels) would be used, if needed, to remove debris stuck in the trash capture device screens.

Vegetation Removal
The proposed project would remove approximately 1,064 square feet (0.02 acre) of ruderal grassland vegetation on the northwest side of the creek to construct the staging area. Vegetation in this area is dominated by fennel ( Foeniculum vulgare), ripgut brome ( Bromus diandrus), and other non-native grasses. All vegetation removed to create this staging area would occur above TOB.

The project would also remove one (1) invasive non-native shrub located immediately adjacent to the concrete-lined channel and would require trimming up to three trees in the mixed woodland adjacent to Poplar Creek along E. Poplar Avenue. The project would require the removal of DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 66 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 8 one (1) shrub and two (2) trees and trimming of a third tree. The shrub proposed for removal is an invasive, non-native Scotch broom ( Cytisus scoparius ) located immediately adjacent to the concrete-lined channel. The trees to be removed include a native coast live oak ( Quercus agrifolia) and a dead tree of unknown species. The tree to be trimmed by the project is a black acacia (Acacia melanoxylon).

Stream Enhancement
During pre-application consultation with the San Francisco Regional Water Quality Control Board (RWQCB), the need to offset project impacts to the Poplar Creek was identified. Stream Enhancement Site 2 has been proposed by the City as a stream enhancement area along the southeastern edge of Poplar Creek where native, pollinator-friendly species would be planted above TOB. The site would include approximately 1,000 square feet (0.02 acre) of stream enhancements located approximately 0.03 mile downstream of Site 1 (Figure 4). Temporary i rrigation would be installed, and a monitoring program would be instituted to ensure that the plantings establish.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 10 Staging and Access
Installation of the trash capture devices would not require road closures. Equipment would be staged in an approximately 1,000 square-foot area north of the channel . Existing ruderal grassland vegetation would be removed from the staging area and the area would be graded to form an earthen pad or an asphalt or concrete parking pad to allow for continued access to the trash capture device for maintenance. In addition, the proposed project would need to trim up to three overhanging trees south of the creek to install the trash capture device.

Construction
Construction would occur over an approximately three-month (approximately 64 working days) duration beginning in April 2022 through Ju ne 2022. No weekend or nighttime work would occur.

Construction would occur between 7:00 A.M. to 5:00 P.M., Monday through Friday. No road closures would occur.

Construction equipment would include an excavator, skidsteer, pickup trucks, 10-wheel dump truck, and telehandler. The excavator or skidsteer would need to operate within the channel to remove the existing concrete-lined section to be replaced by the proposed project. All other equipment operations would be conducted from outside/above the creek. No heavy machinery would be required for the stream enhancement work.

Grading
The installation of the four (4) Roscoe Moss Storm Flo® screens and associated concrete weir wall would add approximately 9.8 cubic yards (CY ), or approximately 180 square feet, of fill to the channel. Approximately 30 CY of fill would be removed from the staging area.

Environmental Setting
Aesthetic resources are often referred to as visual resources because these resources are often plainly visible to the general public. Certain high-quality visual resources are protected such as those in parklands, ridgelines, scenic vistas, and scenic highways. A Scenic Vista is typically defined as a broad panoramic overview of a landscape, often from an elevated perspective, that can be viewed by the public.
1 Highways or roadways are listed by Caltrans or by local jurisdictions and counties as state or county Scenic Highways.2 Visual character or quality is the arrangement of all visual features (i.e., anything visible, such as trees, hills, houses, sky, water, towers, roads, power lines, etc.) in a

There are three state designated scenic highways within San Mateo County, however, none of the designated scenic highways are within close proximity to the project site. The closest officially designated state scenic highway is State Route 280 (SR 280) which is approximately 3.45 miles west of the project site.4 The portion of North Bayshore Boulevard that is adjacent to the project site is designated by the City as a scenic roadway by the City’s General Plan. 5 This road is considered scenic due to the views of Poplar Creek Golf Course and further views of the San Francisco Bay that it offers.

The project site is fully within the Poplar Creek Golf Course, a City-owned and operated course. The golf course is bordered to the north by additional open space and to the east by the San Francisco Bay. North Bayshore Boulevard is along the western border of the project site which separates the golf course from residential neighborhoods to the west. Site 1, which lies mostly within Poplar Creek, is visible from maintenance buildings on the golf course, East Poplar Avenue and Bayshore Boulevard. Stream Enhancement Site 2, which consists of golf course turf along the edge of Poplar Creek, is visible only from the golf course. Existing sources of glare are mainly limited to automobile windshields and reflective building materials associated with residential and commercial uses.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 15 Discussion of Impacts
a) Less than Significant Impact. The scenic vi ew from North Bayshore Boulevard, which is directly adjacent to Site 1 , would be temporarily impacted by proposed project activities through the presence of heavy machinery and construction equipment that could detract from the visual setting. There would be no impact on the scenic view from Bayshore Boulevard during project operation as the trash capture device would be within Poplar Creek and would not be visible from the roadway. While views of the Bay w ould not be obstructed by project activities, the addition of construction equipment adjacent to the project site might temporarily detract from the scenic view from North Bayshore Boulevard. This stretch of North Bayshore Boulevard is designated a scenic roadway by the City’s General Plan. Construction activities would only last for approximately two (2) months. Since the view from the scenic roadway would only be temporarily affected by construction equipment, the impact would be less than significant.
b) No Impact. One (1) invasive shrub that is located immediately adjacent to the concrete-lined channel would be removed and up to three (3) trees in the mixed woodland adjacent to the creek would require trimming in order to install the trash capture device. Multiple native plants would be installed in the stream enhancement area at Stream Enhancement Site 2. The project is not visible from a state scenic highway and thus would have no impacts on a state scenic highway.
c) Less than Significant Impact. The project site is located in an urbanized area surrounded by parks/open space and residential land uses . During construction, temporary impacts would occur to the existing visual quality of the surrounding areas at the golf course. The presence of construction equipment in the staging area could be seen as a detriment to the aesthetic value of the project site. However, these disturbances would be brief. The placement of the trash capture device into Poplar Creek could be seen as a detraction from the visual character of the creek itself. Poplar Creek is listed as a private creek according to the City’s General Plan and as such, Policy C/OS-2.2 stated above would apply. The addition of new native vegetation at the stream enhancement site would enhance the aesthetic and habitat value of the project site in the long term and therefore offset any potential negativ e impacts to aesthetic value caused by the trash capture device installation. Impacts would remain less than significant.
d) No Impact. Construction of the proposed project would not create any new light sources or sources of glare. The trash capture devic e nor the stream enhancement area would have lighting. There would be no impact.

determining whether impacts to agricultural
resources are significant environmental
effects, lead agencies may refer to the
California Agricultural Land Evaluation and
Site Assessment Model (1997) prepared by

Regulatory Setting
Farmland Mapping and Monitoring Program
The California Department of Conservation’s Farmland Mapping and Monitoring Program (FMMP) assesses the location, quality, and quantity of agricultural land and conversion of these lands over time. Agricultural land is rated according to soil quality and i rrigation status. The best quality land is called Prime Farmland. In CEQA analyses, the FMMP classifications and published county maps are used, in part, to identify whether agricultural resources that could be affected are present on-site or in the project site.
6 California Land Conservation Act
The California Land Conservation Act (Williamson Act) enables local governments to enter into contracts with private landowners to restrict parcels of land to agricultural or related open space uses. In return, landowners receive lower property tax assessments. In CEQA analyses, identification of properties that are under a Williamson Act contract is used to also identify sites that may contain agricultural resources or are zoned for agricultural uses. 7 Fire and Resource Assessment Program
The California Department of Forestry and Fire Protection (CAL FIRE) identifies forest land, timberland, and lands zoned for timberland production that can (or do) support forestry resources. 8 Programs such as CAL FIRE’s Fire and Resource Assessment Program and are used to identify

Environmental Setting
The project site does not contain any farmland or forestry land and is not designated for agricultural or forestry uses or Prime, Statewide, or Locally Important Farmland.10 The project site is designated as Urban and Built-Up Land. 11 The proposed project is located within a concrete-lined, intermittent creek on a City-owned and operated golf course. Surrounding land is developed with residential, open space, and light industrial uses.

Discussion of Impacts
a-e) No Impact. There are no agricultural or forestry resources within the project site. There are no Prime, Unique, Statewide or Locally Important farmlands in the area. The project site is not under a Williamson Act Contract, nor is the project zoned as forest land or timber production. Project work would be confined to the staging area above the creek, the creek itself, and the stream enhancement area. All these areas are City owned properties that are not used for agricultural purposes. N o impacts to agricultural or forestry resources would occur.

b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non-attainment under an applicable federal or state
ambient air quality standard?

c) Expose sensitive receptors to substantial pollut ant concentrations?

d) Result in other emissions (such as those leading to
odors) affecting a substantial number of people?

Environmental Setting
The project site is in the San Francisco Bay Area air basin, where air quality is monitored and regulated by the Bay Area Air Quality Management District (BAAQMD). Ambient concentrations of key air pollutants have decreased considerably over the course of the last several decades. Air pollution is generated by anything that burns fuel (including but not limited to cars and trucks, construction equipment, backup generators, boilers and hot water heaters, barbeques and broilers, gas-fired cooking ranges and ovens, fireplaces, and wood-burning stoves), almost any evaporative emissions (including the evaporation of gasoline from service stations and vehicles, emissions from food as it is cooked, emissions from paints, cleaning solvents, and adhesives, etc.), and other processes (fugitive dust generated from roadways and construction activities, etc.).

A sensitive receptor is generally defined as a location where human populations, especially children, seniors, and sick persons, are located where there is a reasonable expectation of continuous human exposure to air pollutants. These typically include residences, hospitals, and schools. The site is surrounded by residential, commercial, and light industrial land uses, with no sensitive receptors near the project site. The primary sensitive receptors in the vicinity are residents in the homes along the southeastern edge of East Poplar Avenue and the southwestern edge of US -101, parallel to North Bayshore Boulevard, which may include children, elderly people, or people with respiratory illnesses. The receptors are located approximately 290 feet and 380 feet from Site 1, respectively.

Regulatory Setting
The Bay Area is currently classified as “attainment” or “unclassifiable” with respect to every National Ambient Air Quality Standard (NAAQS) except ozone and fine particulate matter smaller than DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 78 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 20 2.5 microns (PM2.5), for which it is still classified as “nonattainment.” 12 Ozone concentrations in the Bay Area have also decreased considerably over the last several decades, but NAAQS are required to be set to be protective of public health “allowing an adequate margin of safety” and have also become more stringent. Prior to 2008, attaining the ozone NAAQS required that the “design value” --i.e., the peak 8-hour average concentration on the 4 th-worst day of the year (averaged over three consecutive years) --be below 0.08 parts per million (ppm); the Bay Area was classified as “marginal” nonattainment with respect to that standard.13 In 2008, the ozone NAAQS was revised to 0.075 ppm.

Therefore, while U.S. Environmental Protection Agency ( EPA) has not yet finalized its attainment designations for the 2008 ozone standard, it is proposing to designate the Bay Area as “marginal nonattainment” (0.076 - 0.086 ppm) with respect to that standard.14 The State of California also has its own ambient air quality standards (CAAQS) which are equivalent to or more stringent than the NAAQS; the Bay Area is currently classified as nonattainment with respect to the CAAQS for ozone, particulate matter smaller than 10 microns (PM10), and PM2.5.15 Discussion of Impacts

Project construction would produce fugitive dust (PM 10 and PM2.5) during ground disturbance and would generate carbon monoxide, ozone precursors, and other emissions from vehicle and equipment operation. BAAQMD released a Clean Air Plan (CAP) for the Bay Area in 2010 and updated it in 2017 (2017 CAP), which would be the applicable air quality plan for the proposed project.

Projects that result in regional growth in population, employment, or vehicle miles traveled (VMT) and exceed the estimates used to develop the 2017 CAP, which are based on growth projections from the Association of Bay Area Governments (ABAG) and local general plans, would be inconsistent with the 2017 CAP. Accordingly, projects that propose development that is consistent with the growth anticipated by ABAG and local general plans would be consistent with the 2017 CAP.

As described below in Section X I, Land Use and Planning, the project would be consistent with the City of San Mateo General Plan policies. The project would involve placement of a trash capture device and enhancement of habitat within the project site. The project would not induce population growth. During project operation, one (1) to two (2) maintenance workers would be on-site to remove captured trash two (2) to three (3) times per year at the

No substantial traffic trips would be generated during operation; therefore, no significant VMT effects are anticipated. The project would not generate significant long-term air quality emissions as the project proposes no new development or change in land use. Accordingly, the project would not conflict with the 2017 CAP. Impacts would be less than significant. b) Less Than Significant Impact. The San Francisco Bay Area is in non-attainment for ozone and particulate matter, including PM 10 (State status) and PM 2.5 (State status and 24-hour national standard). Construction activities would result in short-term increases in criteria pollutant emissions from the use of heavy equipment that generates dust, exhaust, and tire-wear emissions; soil disturbance; materials used in construction; and construction traffic.

The BAAQMD provides preliminary screening criteria in the 2017 BAAQMD CEQA Guidelines to indicate whether a project would result in the generation of construction-related criteria air-pollutants and/or precursors that exceed defined thresholds of significance. The project, with the basis construction mitigation control measures below (Mitigation Measure AIR-1), meets the screening criteria indicating a less -than-significant impact for construction-related activities as the project does not propose any applicable land use or development exceed such criteria. As discussed under item a) , the project would not result in significant criteria pollutant emissions or other significant air quality impacts during operation because the project would be consistent with the 2017 CAP. Therefore, the project would not result in a cumulatively considerable net increase of any criteria pollutant. Impacts would remain less than significant.
c) Less Than S ignificant Impact with Mitigation Incorporated. Sensitive receptors are typically defined as the segment of the population most susceptible to air quality effects including children, the elderly, and the sick, as well as land uses such as schools, hospitals, parks, and residential communities. Sensitive receptors located within 1,000 feet of the construction area include residential dwellings on the southeastern side of East Poplar Avenue and on the southwestern side of US-101. The sensitive receptors closest to the site would be the residential dwellings to the south and southwest of Site 1, approximately 290 feet from Site 1. Sensitive receptors could be exposed to temporary air pollutants from construction activities, such as fugitive dust, ozone precursors, and carbon monoxide.

Construction emissions would be temporary, lasting approximately 64 working days, and would not have long-term effects on air quality in the Bay Area. Thus, there may be temporary significant impacts from fugitive dust during construction that would require implementation of Mitigation Measure AIR-1.

Impact AIR -1: Construction activities could produce fugitive dust fugitive dust (PM 10 and
PM2.5) during ground disturbance, which the Bay Area is currently classified as nonattainment.

Mitigation Measure AIR -1: The Bay Area Air Quality Management District (BAAQMD) recommends basic construction measures to ensure minimal impacts on DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 80 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 22 regional air quality. The contractor would be responsible for implementing the following basic measures during construction:
• All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas) will be watered two (2) times per day.
• All haul trucks transporting soil, sand, or other loose material off-site will be covered.
• All visible mud or dirt track-out onto adjacent public roads will be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited.
• Idling times will be minimized either by shutting equipment off when not in use or reducing the maximum idling time to five (5) minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations).
• Clear signage will be provided for construction workers at all access points. • All construction equipment will be maintained and properly tuned in accordance with manufacturer specifications, and all equipment will be checked by a certified visible emissions evaluator.
• A publicly visible sign with the telephone number and person to contact at the lead agency regarding any dust complaints will be posted in or near the project site. The contact person will respond to complaints and take corrective action within 48 hours. BAAQMD ‘s phone number will also be visible to ensure compliance with applicable regulations.

Construction-related activities would also result in temporary project-generated emission of diesel particulate matter (DPM, a toxic air contaminant) exhaust emission, from off -road, heavy-duty diesel equipment for site preparation, grading and other construction activities.

While sensitive receptors near the construction area may be exposed to contaminants, exhaust emission would disperse rapidly from the site and would not substantially impact the nearest sensitive rec eptors. In addition, new construction equipment has been subject to increasingly stringent emissions requirements at the Federal level (e.g., 40 Code of Federal Regulations [CFR] 89 and 1039), designated “Tier 1”, “Tier 2”, “Tier 3”, etc.; older construction equipment is subject to potential retrofit requirements required by the State of California (13 CCR 2449, 13 CCR 2450-2466, and 17 CCR 93116). Tier 4 diesel engines would be utilized by the contractor during construction to reduce construction toxic air contaminant emissions. As a result, sensitive receptors in the vicinity of the project would not be exposed to substantial pollutant concentrations, and impacts would be less than significant. d) Less Than Significant Impact. Construction activities would involve the use of gasoline or diesel-powered equipment that emits exhaust fumes . These activities would take place intermittently throughout the workday, and the associated odors are expected to dissipate DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 81 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 23 within the immediate vicinity of the work area. Persons near the construction work area may find these odors objectionable. However, the project would not include uses that have been identified by BAAQMD as potential sources of objectionable odors, such as restaurants, manufacturing plants, landfills, and agricultural and industrial operations. During device maintenance and trash removal, objectionable odors might be produced when accumulated trash is disturbed. These odors are also expected to dissipate within the immediate vicinity of the work area. The infrequency of the emissions, rapid dissipation of the exhaust and other odors into the air, and short-term nature of the construction activities would result in less than significant odor impacts.

Regulatory Setting
Federal and State
Sensitive Natural Communities
Sensitive natural communities include habitats that fulfill special functions or have special values.

Natural communities considered sensitive are those identified in local or regional plans, policies, regulations, or by the CDFW. CDFW ranks sensitive communities as "threatened" or "very threatened" and keeps records of their occurrences in its California Natural Diversity Database. 1617
Vegetation alliances are ranked 1 through 5 in the CNDDB based on NatureServe's methodology, with those alliances ranked globally (G) or statewide (S) as 1 through 3 considered sensitive. 18 Impacts to sensitive natural communities identified in local or regional plans, policies, or regulations or those identified by the CDFW or U.S. Fish and Wildlife Service (USFWS) must be considered and evaluated under CEQA (CCR Title 14, Div. 6, Chap. 3, Appendix G). In addition, this general class includes oak woodlands that are protected by local ordinances under the Oak Woodlands Protection Act.

Waters of the United States Regulated by the U.S. Army Corps of Engineers The Corps regulates “Waters of the United States” under Section 404 of the Clean Water Act (CWA).

Waters of the United States are defined in CFR as including the territorial seas, and waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, such as tributaries, lakes and ponds, impoundments of waters of the U.S., and wetlands that are hydrologically connected with these navigable features (33 CFR 328.3). Potential wetland areas, according to the three criteria used to delineate wetlands as defined in the U.S. Army Corps of Engineers Wetlands Delineation Manual , are identified by the presence of (1) hydrophytic vegetation, (2) hydric soils, and (3) wetland hydrology. 19 Unvegetated waters including lakes, rivers,
and streams may also be subject to Section 404 jurisdiction and are characterized by an ordinary high water mark (OHWM) identified based on field indicators such as the lack of vegetation, sorting of sediments, and other indicators of flowing or standing water. The placement of fill material into

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 26 Waters of the United States generally requires a permit from the Corps under Section 404 of the CWA.

The Corps also regulates construction in navigable waterways of the U.S. through Section 10 of the Rivers and Harbors Act (RHA) of 1899 (33 United States Code [USC] 403). Section 10 of the RHA requires Corps approval and a permit for excavation or fill, or alteration or modification of the course, location, condition, or capacity of, any port, roadstead, haven, harbor, canal, lake, harbor or refuge, or enclosure within the limits of any breakwater, or of the channel of any navigable water of the United States. Section 10 requirements apply only to navigable waters themselves, and are not applicable to tributaries, adjacent wetlands, and similar aquatic features not capable of supporting interstate commerce.

Waters of the State, Including Wetlands
The term “Waters of the State” is defined by the Porter -Cologne Act as “any surface water or groundwater, including saline waters, within the boundaries of the state.” The SWR CB and nine (9) RWQCB protect waters within this broad regulatory scope through many different regulatory programs. Waters of the State in the context of a CEQA Biological Resources evaluation include wetlands and other surface waters protected by the State Wetland Definition and Procedures for Discharges of Dredged or Fill Material to Waters of the State. 20 The SWRCB and RWQCB issue
permits for the discharge of fill material into surface waters through the State Water Quality Certification Program, which fulfills requirements of Section 401 of the CWA and the Porter-Cologne Water Quality Control Act. Projects that require a Clean Water Act permit are also required to obtain a Water Quality Certification. If a project does not require a federal permit but does involve discharge of dredge or fill material into surface waters of the State, the SWRCB and RWQCB may issue a permit in the form of Waste Discharge Requirements.

Sections 1600-1616 of California Fish and Game Code
Streams and lakes, as habitat for fish and wildlife species, are regulated by CDFW under Sections 1600-1616 of California Fish and Game Code (CFGC). Alterations to or work within or adjacent to streambeds or lakes generally require a 1602 Lake and Streambed Alteration Agreement. The term “stream,” which includes creeks and rivers, is defined in the California Code of Regulations (CCR) as “a body of water that flows at least periodically or intermittently through a bed or channel having banks and supports fish or other aquatic life [including] watercourses having a surface or subsurface flow that supports or has supported riparian vegetation” (14 CCR 1.72). The term “stream” can include ephemeral streams, dry washes, watercourses with subsurface flows, canals, aqueducts, irrigation ditches, and other means of water conveyance if they support aquatic life, riparian vegetation, or stream -dependent terrestrial wildlife.
21 Riparian vegetation has been defined as

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 27 “vegetation which occurs in and/or adjacent to a stream and is dependent on, and occurs because of, the stream itself.” 22 Removal of riparian vegetation also requires a Section 1602 Lake and Streambed Alteration Agreement from CDFW.

Endangered and Threatened Plants, Fish, and Wildlife
Specific species of plants, fish, and wildlife species may be designated as threatened or endangered by the federal Endangered Species Act (ESA), or the California Endangered Species Act (CESA).

Specific protections and permitting mechanisms for these species differ under each of these acts, and a species’ designation under one (1) law does not automatically provide protection under the other.

The ESA (16 USC 1531 et seq.) is implemented by the USFWS and the National Marine Fisheries Service (NMFS). The USFWS and NMFS maintain lists of endangered and threatened plant and animal species (referred to as "listed species"). "Proposed" or "candidate" species are those that are being considered for listing and are not protected until they are formally listed as threatened or endangered. Under the ESA, authorization must be obtained from the USFWS or NMFS prior to take of any listed species. “Take” under the ESA is defined as “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct.” Take under the ESA includes direct injury or mortality to individuals, disruptions in normal behavioral patterns resulting from factors such as noise and visual disturbance and impacts to habitat for listed species. Actions that may result in take of an ESA -listed species may obtain a permit under ESA Section 10, or via the interagency consultation described in ESA Section 7. Federally listed plant species are only protected when take occurs on federal land.

The ESA also provides for designation of critical habitat, which are specific geographic area s containing physical or biological features “essential to the conservation of the species.” Protections afforded to designated critical habitat apply only to actions that are funded, permitted, or carried out by federal agencies. Critical habitat designations do not affect activities by private landowners if there is no other federal agency involvement.

The CESA (CFGC 2050 et seq.) prohibits a take of any plant and animal species that the CFGC determines to be an endangered or threatened species in California. CESA regulations include take protection for threatened and endangered plants on private lands, as well as extending this protection to candidate species which are proposed for listing as threatened or endangered under CESA. The definition of a "take" under CESA ("hunt, pursue, catch, capture, or kill, or attempt to hunt, pursue, catch, capture, or kill") only applies to direct impact to individuals, and does not extend to habitat impacts or harassment. CDFW may issue an Incidental Take Permit under CESA to authorize take if it is incidental to otherwise lawful activity and if specific criteria are met. Take of these species is also authorized if the geographic area is covered by a Natural Community Conservation Plan (NCCP), as long as the NCCP covers that activity.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 28 Fully Protected Species and Designated Rare Plant Species This category includes specific plant and wildlife species that are designated in the CFGC as protected even if not listed under CESA or ESA. Fully Protected Species includes specific lists of birds, mammals, reptiles, amphibians, and fish designated in CFGC. Fully protected species may not be taken or possessed at any time. No licenses or permits may be issued for take of fully protected species, except for necessary scientific research and conservation purposes. The definition of "take" is the same under the California Fish and Game Code and the CESA. By law, CDFW may not issue an Incidental Take Permit for Fully Protected Species. Under the California Native Plant Protection Act (NPPA), CDFW has listed 64 “rare” or “endangered” plant species, and prevents “take”, with few exceptions, of these species. CDFW may authorize take of species protected by the NPPA through the Incidental Take Permit process, or under a NCCP.

Special Protection for Nesting Birds and Bats
The federal Bald and Golden Eagle Protection Act provides relatively broad protections to both of North America’s eagle species (bald eagle [Haliaeetus leucocephalus ] and golden eagle [Aquila chrysaetos]) that in some regards are similar to those provided by the ESA. In addition to regulations for special-status species, most native birds in the United States, including non-status species, have baseline legal protections under the Migratory Bird Treaty Act of 1918 and CFGC, i.e., sections 3503, 3503.5 and 3513. Under these laws/codes, the intentional harm or collection of adult birds as well as the intentional collection or destruction of active nests, eggs, and young is illegal. For bat species, the Western Bat Working Group (WBWG) designates conservation status for species of bats, and those with a high or medium-high priority are typically given special consideration under CEQA.

Essential Fish Habitat
The Magnuson-Stevens Fishery Conservation and Management Act provides for conservation and management of fishery resources in the U.S., administered by NMFS. This Act establishes a national program intended to prevent overfishing, rebuild overfished stocks, ensure conservation, and facilitate long-term protection through the establishment of Essential Fish Habitat (EFH). EFH consists of aquatic areas that contain habitat essential to the long-term survival and health of fisheries, which may include the water column, certain bottom types, vegetation (e.g., eelgrass (Zostera spp.)), or complex structures such as oyster beds. Any federal agency that authorizes, funds, or undertakes action that may adversely affect EFH is required to consult with NMFS.

Species of Special Concern, Movement Corridors, and Other Special-status Species under CEQA.

To address additional species protections afforded under CEQA, CDFW has developed a list of special species as “a general term that refers to all of the taxa the CNDDB is interested in tracking, regardless of their legal or protection status.” This list includes lists developed by other organizations, including for example, the Audubon Watch List Species, the Bureau of Land Management Sensitive Species, and USFWS Birds of Special Concern. Plant species on the California Native Plant Society (CNPS) Inventory of Rare and Endangered Plants (Inventory) with California Rare Plant Ranks (Rank) of 1 and 2, as well as some with a Rank of 3, are also considered special-status plant species DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 87 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 29 and must be considered under CEQA. Some Rank 3 species and all Rank 4 species are typically only afforded protection under CEQA when such species are particularly unique to the locale (e.g., range limit, low abundance/low frequency, limited habitat) or are otherwise considered locally rare.

Additionally, any species listed as sensitive within local plans, policies and ordinances are likewise considered sensitive. Movement and migratory corridors for native wildlife (including aquatic corridors) as well as wildlife nursery sites are given special consideration under CEQA.

Local Plans and Policies
San Mateo County General Plan
The San Mateo County General Plan, Chapter 1. Vegetative, Water, Fish and Wildlife Resources Policies contains policies pertaining to the following biological resources categories:
• Wetlands, streams, riparian, and aquatic areas (Policy 1.26, 1.37, 1.41, 1.49, etc.) • Vegetation Resources (Policy 1.25)
• Wildlife Species (Policy 1.27)
• Wildlife Corridors (Policy 1.29)
City of San Mateo Tree Ordinance
City of San Mateo Tree Ordinance. The City of San Mateo Tree Ordinance requires a permit for the removal, major pruning of more than one-fourth of the crown, or removal of any roots within a distance equal to six (6) times the diameter of the trunk of any Heritage tree from any parcel of property in the City. The Ordinance defines a “Heritage trees” as:

1. Any oak having a trunk diameter or diameter at breast height (DBH) of 10 inches or more, measured at 4.5 feet (54 inches) above ground level.

2. Any tree with a trunk diameter of 15 inches or more, measured at 4.5 feet (54 inches) above ground level.

3. Multi-stem trees. Trees with more than one (1) stem (arising at or below 54 inches) shall be measured at the smallest diameter point below the main union of all stems unless the union occurs below grade, in which case each stem shall be measured as a stand-alone tree. For oak trees, if one (1) stem is 10 inches or more in diameter, the tree will constitute one (1) Heritage Tree. For all other species, if one (1) stem is fifteen inches or more in diameter, the tree will constitute one (1) Heritage Tree.

4. Any tree or stand of trees designated by resolution of the City Council to be of special historical value or of significant community benefit; or

5. A stand of trees, the nature of which makes each dependent on the others for survival.

Environmental Setting
The approximately 0.10-acre project site is located immediately north of the intersection of East Poplar Avenue and North Bayshore Boulevard and adjacent to the Poplar Creek Golf Course, and within Poplar Creek, an intermittent, concrete-lined stream located in San Mateo, California. The project site includes all areas directly affected by the p roject, as well as adjacent areas of natural DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 88 of 662

Additional details of the local setting are below.

Soils and Topography
The overall topography of the project site is flat with elevations ranging from approximately 0 to 2 feet above sea level. According to the Soil Survey of San Mateo County, Eastern Part and San Francisco County, the project site consists of Urban land-Orthents, reclaimed complex. The soil series of the project site’s mapping units is summarized below.23
Urban land-Orthents, reclaimed complex, 0 to 2 percent slopes: This map unit is in areas that were once part of San Francisco Bay and adjacent tidal flats. This unit is about 65 percent Urban land and 30 percent Orthents, reclaimed. Urban land consists of area covered by asphalt, concrete, buildings, and other structures. Orthents consist of soils that are very deep and poorly drained and are in areas that have been filled. They are comprised of soil material, gravel, broken cement and asphalt, bay mud, and solid waste materials. This unit also contains small inclusions of Reyes clay, Novato clay, and where those inclusions in present the soil is hydric. These soils are not considered hydric and are poorly drained with slow runoff.
24 Climate and Hydrology
The project site is located in the coastal region of the City of San Mateo in San Mateo C ounty. The average monthly maximum temperature in the area is 66 degrees Fahrenheit, while the average monthly minimum temperature is 50 degrees Fahrenheit. Predominantly, precipitation falls as rainfall between November and March with an annual average precipitation of 20 inches.

The local watershed is San Francisco Bay Estuaries (HUC 12: 180500041001) and the regional watershed is San Francisco Bay (HUC 8: 18050004). The project site is located in the upper portion of the San Francisco Bay watershed. There is a blue-line stream, Poplar Creek in the project site.25 Land Use
The surfaces of the project site and immediate surrounding areas have been rendered largely impermeable by the construction of the concrete lined channel, buildings, maintenance lots, and surrounding streets (Google Earth 2021) . Undeveloped area s consist of ruderal upland, and the surrounding golf course turf. Historically, the project site was more heavily vegetated with sections used for storage and staging areas.26

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 34 Terrestrial Land Cover
Developed Area (no vegetation alliance). CDFW Rank: None.

The developed areas total 0.04 acre in the project site (Figure 5 and Figure 6). Developed areas are characterized by concrete-lined banks in the channel, a cement culvert forming a bridge across the channel, as well as cement or gravel lots associated with the maintenance yards of the nearby facilities. Developed areas also include landscaped turf within the Poplar Creek Golf Course. Sparse ruderal vegetation occurs growing in cement seams. This community is not considered sensitive by San Mateo County, CDFW, or any other regulatory entity.

Mixed ornamental woodland (no vegetation alliance). CDFW Rank: None.

Mixed ornamental woodland is located above TOB along the southeast side of the channel . The woodland varies from approximately 5 to 15 feet in width in a strip of earth between the channel and the East Poplar Avenue sidewalk (Figure 5). The mixed ornamental woodland is less than 0.01 acre in size and is composed of a planted coast live oak ( Quercus agrifolia), blackwood acacia ( Acacia melanoxylon) and an unidentified dead tree. The understory consisted of sparse ruderal, non -native grasses and bare ground. This cover type does not meet any of the membership requirements for any vegetation alliances and is not considered sensitive.

Ruderal Upland (multiple vegetation alliances). CDFW Ranks: None.

Although not described in the literature, ruderal upland includes areas that have been partially developed or have been used in the past. However, these areas are not currently in use and have been allowed to revert to a semi-natural condition. Ruderal upland is common throughout California in both rural and urban settings. Vegetation at the TOB of this section of Poplar Creek is dominated by ruderal upland species (Figure 5). Within the project site, most ruderal upland vegetation is dominated by dense stands of fennel ( Foeniculum vulgare) interspersed with other non-native upland grass species. The majority of the ruderal upland area meets the membership rules of the Foeniculum vulgare Herbaceous Semi -Natural Alliance due to the density of fennel growth. Other upland species found in this area are Bermuda grass ( Cynodon dactylon), wild oats ( Avena sp.), ripgut brome (Bromus diandrus). A large Scotch broom (Cytisus scoparius) shrub also occurs within this land cover type, along the northwester edge of Poplar Creek.

Aquatic Resources
Intermittent stream. (No Alliance). CDFW Rank: Sensitive Poplar Creek is identified in the NWI as an intermittent stream at and below the OHWM and occupies approximately 0.03 acre of the project site (Figure 5). Poplar Creek is ranked as a sensitive aquatic community and is considered a water of the United States as well as a water of the state. From the project site, flows from Poplar Creek continue outside of the project site in a northeasterly direction for approximately 3,000 feet, at which time the channel becomes unlined and begins to flow in the southeasterly direction. This earthen channel conveys flow for approximately 700 feet before discharging into the open forebay of the Poplar Pump Station. Flow from the forebay enters the DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 93 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 35 pump station intake and is discharged through the earthen flood control levee into the San Francisco Bay.

At the time of the October 2020 survey there was approximately one (1) inch of water flowing in the channel. No substantial precipitation had occurred in the recent few weeks and the flow is presumed to originate largely from nuisance runoff from landscaping or other artificial sources upstream. The channel was observed to be fully concrete lined in the banks and bed in the entire p roject site. The cement bottom precludes vegetation from establishing. Some sediment has accumulated within the channel, which has allowed sparse vegetation to establish. A survey of the vegetated area within the stream channel following the methods of the U.S. Army Corps of Engineers Wetlands Delineation Manual, the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region determined that wetlands have not established in or around the channel. The cement-lined area along the stream that lies at and below TOB is not considered a sensitive vegetation community because the area is largely unvegetated and precludes the growth of native, sensitive vegetation communities.

Special-Status Species
Special-Status Plants
Based upon a review of the resource databases, 61 special -status plant species have been documented in the vicinity of the project site. Only one (1) special-status plant species, Franciscan onion (Allium peninsulare var. franciscanum), has been documented within 2 miles of the project site. This species and the other 60 species recorded in the neighboring CNDDB quadrangles are presumed absent because the project site consists mostly of unvegetated hardscape and there are no native plant communities present. All of these species documented from the greater vicinity are unlikely or have no potential to occur for one (1) or more of the following reasons:
• Hydrologic conditions (e.g., tidal, riverine) necessary to support the special -status plant species are not present in the project site;
• Edaphic (soil) conditions (e.g., volcanic tuff, serpentine) necessary to support the special-status plant species are not present in the project site; • Associated natural communities (e.g., interior chaparral, tidal marsh) necessary to support the special-status plant species are not present in the project site; • The historical landscape and/or habitat(s) of the project site were not suitable habitat prior to land/type conversion (e.g., reclaimed shoreline) to support the special-status plant species; • Land use history and contemporary management (e.g., grading, intensive landscaping) has degraded the localized habitat necessary to support the special -status plant species and created a lack of viable seed bank due to historic soil alterations; • Non-native species competition.

Special-Status Wildlife
No special-status wildlife species were observed in the project site during the site assessment. While none were observed, 36 special-status wildlife species have been documented to occur in the South DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 94 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 36 San Francisco, Hunters Point, Montara Mountain and San Mateo USGS 7.5’ Q uadrangles.27 Of these, only ten species are documented to occur within 2 miles of the project site in the CNDDB.28 Most of the special-status species known from the vicinity of the project site were determined to have no potential, or are unlikely to occur due to one (1) or more of the following reasons:
• Aquatic habitats necessary to support the special -status wildlife species (e.g., vernal pools, freshwater streams/rivers) are not present in the project site; • Vegetation communities (e.g., tidal or freshwater marsh, grassland, oak woodlands, old-growth coniferous forest, riparian woodland/forest) that provide nesting and/or foraging resources necessary support the special-status wildlife species are not present in the project site;
• Structures or vegetation (e.g., caves, old-growth trees) necessary to provide nesting or cover habitat to support the special-status wildlife species are not present in the project site; • Host plants necessary to provide larval and nectar resources required for the completion of life cycles for specific special-status insects are not present in the project site; • The project site is outside the special -status wildlife species’ local documented range, or specifically nesting range (generally applies to birds); • The project site is separated from suitable habitats by roads with high traffic volume and is embedded within a highly urbanized setting that does not contain suitable habitat; and • The project site is surrounded by urban areas and has little to no connectivity to open spaces that would support special-status species.

Based upon the database and literature review, no special-status species documented in the vicinity have the potential to occur within the project site. However, given the proximity to the project site of suitable habitat for some special-status species, three (3) species warrant further discussion and are addressed below.

California Ridgway’s rail ( Rallus. longirostris obsoletus ; CRR). Federal Endangered, State Endangered, CDFW Fully Protected Species. Unlikely. Formerly known as California clapper rail, CRR is the resident Ridgway’s/clapper rail subspecies of northern and central California. Although more widespread in the past, it is currently restricted to the San Francisco Bay estuary. The CRR occurs only within salt and brackish marshes. Important CRR habitat components include well-developed tidal sloughs and secondary channels, and cordgrass ( Spartina spp.) beds in the lower marsh zone, dense salt marsh vegetation for cover, nest sites, and brooding areas, intertidal mudflats, gradually sloping banks of tidal channels, abundant invertebrate food resources, and transitional vegetation at the marsh edge to serve as high tide refuge. In south and central San Francisco Bay and along the perimeter of San Pablo Bay, CRR typically inhabits salt marshes dominated by pickleweed and cordgrass. Brackish marshes supporting CRR occur along major

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 37 sloughs and rivers of San Pablo Bay and along tidal sloughs of Suisun Marsh. Nesting occurs from March through July, with peak activity in late April to late May. CRR nests, constructed of wetland vegetation and platform-shaped, are placed near the ground in clumps of dense vegetation, usually in the lower marsh zone near small tidal channels.

CRR has been documented approximately 0.5-mile northeast of the project site.29 Based on aerial imagery, this occurrence exists in a small patch of salt marsh along the edge of the San Francisco Bay.30 Despite the close proximity of this occurrence, it is unlikely that CRR would inhabit the project site given that the project site does not contain the dense salt marsh vegetation and intertidal mudflats that this species requires for breeding and foraging. Additionally, the project site is more than 700 feet from any suitable habitat, suggesting that any noise impacts associated with project activities would be unlikely to impact CRR breeding behaviors, which are highly dependent on vocalizations. CRR use of the project site, if it were to occur, would be limited to occasional movements through the project site between patches of more suitable habitat; but they would not utilize the area for extended periods of time. Therefore, it is unlikely that CRR would occur within the project site, and no protocol level CRR surveys would be required due to the distance of the project site from any suitable habitat.

Burrowing owl (Athene cunicularia). CDFW Species of Special Concern. Unlikely. The burrowing owl occurs as a year-round resident and winter visitor in much of California’s lowlands, inhabiting open areas with sparse or non-existent tree or shrub canopies. Typical habitat is annual or perennial grassland, although human-modified areas such as agricultural lands and airports are also used. 31 This species is dependent on burrowing mammals to provide the burrows that are used characteristically for shelter and nesting, and in northern California is typically found in close association with California ground squirrels (Otospermophilus beecheyi). Manmade substrates such as pipes or debris piles may also be occupied in place of burrows. Prey consists of insects and small vertebrates. Breeding typically takes place from March to July.

Burrowing owl has been documented throughout San Mateo County, with the closest documented occurrence approximately 1.25 miles southeast of the project site. 32 However, habitat for this species
within the project site is generally marginal. A small ruderal grassland is present along the northwestern side of the project site near the intersection with North Bayshore Boulevard; however,

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 38 no small mammal burrows or burrow surrogates were observed during the site visit that might provide shelter for wintering or breeding burrowing owl. Therefore, it is unlikely that burrowing owls would occur within the project site.

Steelhead – central California coast (CCC) Distinct Population Segment (DPS) ( Oncorhynchus mykiss irideus) Federal Threatened. Unlikely. This DPS includes all naturally spawned populations of steelhead (and their progeny) in California streams from the Russian River to Aptos Creek, and the drainages of San Francisco and San Pablo Bays eastward to the Napa River ( inclusive), excluding the Sacramento-San Joaquin River Basin. Steelhead typically migrate to marine waters after spending two (2) years in freshwater, though they may stay up to seven (7). They then reside in marine waters for two (2) to three (3) years prior to returning to their natal stream to spawn as four (4) or five (5)-year-olds. Steelhead adults typically spawn between December and June. Preferred spawning habitat for steelhead is in perennial streams with cool to cold-water temperatures, high dissolved oxygen levels, and fast flowing water. Abundant riffle areas (shallow areas with gravel or cobble substrate) for spawning and deeper pools with sufficient riparian cover for rearing are necessary for successful breeding.

The closest CCC steelhead supporting stream is San Mateo Creek, approximately one (1) mile southeast of the project site.33 Despite the documented presence of steelhead in nearby waterways, the concrete lined portion of Poplar Creek that passes through the project site would not suppor t steelhead populations. While the stream held water during the October 2020 site visit, flows were extremely low and likely resulted from various urban runoff sources. There is no gravel or cobble substrate that would support the deposition of eggs, and thus a breeding population. Additionally, it is unlikely that steelhead would travel through Poplar Creek to reach better breeding grounds upstream, particularly because Poplar Creek proceeds into lined and underground storm drainages immediately upstream of the project site. Additionally, the mouth of Poplar Creek where it drains into the San Francisco Bay is also channeled through a pump station before discharging to the Bay, therefore rendering it completely disconnected from the Bay. Given the disconnection from the Bay, and lack of suitable breeding habitat within the project site or in the immediate vicinity, and barriers to movement that under most circumstances would prevent this species from entering the project site, steelhead are unlikely to occur within the project site.

Wildlife Corridors and Native Wildlife Nursery Sites
No native wildlife nursery sites are present in the project site. Wildlife movement between suitable habitat areas can occur via open space areas lacking substantial barriers. The terms “landscape linkage” and “wildlife corridor” are often used when referring to these areas. The key to a functioning corridor or linkage is that it connects two (2) larger habitat blocks, also referred to as core habitat

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 39 areas.3435 It is useful to think of a “landscape linkage” as being valuable in a regional planning context, a broad scale mapping of natural habitat that functions to join two (2) larger habitat blocks.

The term “wildlife corridor” is useful in the context of smaller, local area planning, where wildlife movement may be facilitated by specific local biological habitats or passages and/or may be restricted by barriers to movement. Above all, wildlife corridors must link two (2) areas of core habitat and should not direct wildlife to developed areas or areas that are otherwise void of core habitat.36 The project site is not within a designated wildlife corridor, as based on the Essential Connectivity Areas habitat mapper. 37 The site is generally located wi thin a dense urban and residential matrix, which is typically considered to serve as a barrier to dispersal for most wildlife species. While common and/or urban-adapted wildlife species presumably utilize the site to some degree for movement at a local scale, the project site itself does not provide corridor functions beyond connecting other small habitat patches in surrounding areas.

Methods
Prior to the site visit, background literature was reviewed to determine the potential presence of sensitive vegetation types, aquatic communities, and special -status plant and wildlife species.

Resources reviewed for sensitive vegetation communities and aquatic features include aerial photography, mapped soil types, the CNPS Online Database, CDFW’s California Natural Diversity Database, and USFWS’s Information for Planning and Consultation (IPaC) database. For database queries, the San Mateo and eight (8) surrounding U.S. Geological Survey (USGS) 7.5- minute quadrangles were included as the focal search area.

In October 2020, WRA biologists conducted a field assessment of the project site to evaluate the potential presence of sensitive vegetation communities and aquatic features and evaluate on -site habitats to determine the potential for occurrence of s pecial-status plant and wildlife species.

Observed plant communities, aquatic features, and plant and wildlife species were noted. Site conditions were noted as they relate to habitat requirements of special -status plant and wildlife species known to occur in the vicinity as determined by the background literature research.

The project site was assessed in terms of potential biological resources impacts on the redevelopment project. This analysis was performed to a level of detail necessary to understand

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 40 what types of major biological impacts are likely to be associated with the proposed project activities, with a focus on the project footprint within the Biological Study Area.

The conclusions of this analysis are based on conditions observed at the time of the field assessments and regulatory policies and practices in place at the time the Biological Resources Technical Report (Appendix C) was prepared; changes that may occur in the future with regard to conditions, policies, or practices could affect the conclusions presented in this assessment.

Discussion of Impacts
a) Less than Significant with Mitigation Incorporated. The biological assessment determined that no special-status bird species have the potential to utilize habitats within the project site. Common native bird species may nest within the project site and may be affected by project activities through visual, auditory, or physical disturbance causing nest abandonment or destruction. Due to the protected status of these species under both the Migratory Bird Treaty Act (MBTA) and CFGC, impacts to common native nesting birds would be considered a potentially significant impact under CEQA. To reduce potential impacts to native nesting birds to a less than significant level, Mitigation Measure BIO -1 would be implemented:

Impact BIO-1: Construction activities and vegetation removal associated with the project could result in the destruction or abandonment of nests of non-status bird species protected under the MBTA, CFGC, and CEQA.

Mitigation Measure BIO -1: To the extent feasible, project- related activities should be avoided during the nesting bird season, generally defined as February 1 through August 31. If project work must occur during the nesting bird season, pre-construction nesting bird surveys must be conducted within 14 days of ground disturbance to avoid disturbance to active nests, eggs, and/or young of nesting birds. These surveys would determine the presence or absence of active nests that may be affected by project activities. It is also recommended that any trees and shrubs in or adjacent to the project site that are proposed for removal and that could be used as avian nesting sites be removed during the non-nesting season (September 1 through January 31).

In the event that a nest of a protected species is located, a no disturbance buffer shall be established around the nest until all young have fledged or the nest otherwise becomes inactive (e.g., due to predation). Suggested buffer zone distances differ depending on species, location, baseline conditions, and placement of nest and will be determined and implemented in the field by a qualified biologist.
b) Less than Significant Impact. Sensitive natural communities within the project site include an intermittent stream, which is located within a concrete-lined channel.

Project impacts by land cover type and community are depicted in Figure 7. The RWQCB required that the project shall be designed to minimize and avoid impacts to the intermittent stream. The installation of the trash capture device will result in placement of fill i n the DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 99 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 41 concrete-lined channel . The purpose of the trash capture device itself will benefit water quality and hydrology in the stream by helping the City effectively capture and remove trash.

Additionally, implementation of downstream stream enhancements will minimize any impacts that could result from the additional fill in the concrete-lined channel. Based on these factors, the installation of the trash capture device will result in a less than significant impact to aquatic resources.
c) Less than Significant Impact. The RWQCB required that the project be designed to minimize and avoid impacts to the intermittent stream, which is considered a sensitive resource. The installation of the trash capture device will result in placement of fill in the concrete-lined channel; however, the trash capture device itself will benefit water quality and hydrology by helping the City effectively remove trash from the creek. Additionally, implementation of downstream stream enhancements will minimize any impacts resulting from the additional fill in the concrete-lined channel. Based on these factors, the installation of the trash capture device will result in a less than significant impact to aquatic resources. d) Less than Significant Impact., No portions of the project site provide connectivity between areas of suitable habitat. For terrestrial species, all portions of the project site are within a greater context of urban development, and for aquatic species, there is no connectivity between the project site and upstream freshwater habitats or downstream marine habitats.

No impact will occur to migratory corridors for terrestrial and aquatic species.

The proposed p roject involves the installation of a trash capture device in an intermittent stream. While the project site in general provides suitable cover and habitat for various types of terrestrial wildlife movement, the installation of the trash capture device will not provide a barrier to the dispersal of any wildlife species. Temporary impacts in upland areas associated with staging would also not provide a barrier to dispersal that could not be easily circumnavigated through other similar habitats. The proposed p roject would not result in temporary or permanent changes to movement of volant species. Based on these factors, the installation of the trash capture device will result in a less -than-significant impact to migratory corridors and habitat linkages.
e) Less than Significant Impact . The project would require the removal of two (2) trees and the trimming of a third tree for construction and access. The trees to be removed include a native coast live oak ( Quercus agrifolia) and a dead tree of unknown species (see Table 2, below) located at the top of the southern bank in the mixed ornamental woodland. The tree to be trimmed is a non-native, invasive blackwood acacia. The coast live oak to be removed does not qualify as a Heritage tree per the City of San Mateo tree ordinance, as it has a DBH of 6.2 inches, which is under the 10-inch DBH threshold.

While the impacts under CEQA would be less than significant, and the coast live oak proposed for removal does not meet the definition of a heritage tree per the City’s tree ordinance, the RWQCB has requested that additional trees be planted as part of the stream enhancement.
f) No Impact. There is no Habitat Conservation Plan that applies to projects in the City or County of San Mateo. As such, no impacts would occur.

The following analysis of cultural resource impacts is based on a report compiled by Tom Origer & Associates in October 2021. This report contains confidential information; therefore, this report will be on file with the City of San Mateo and will not be published as a part of this IS/MND.

Environmental Setting
Research on the project site was conducted at the Northwest Information Center (NWIC File No. 21-0231) of the California Historical Information System (CHRIS), and additional documents and maps pertinent to the project were reviewed on file at the Tom Origer & Associates offices. The Area of Potential Effect (APE) is in the City of San Mateo. The APE consists of two (2) areas, a 0.13-acre area within the Poplar Creek channel on the corner of Poplar Avenue and North Bayshore Boulevard, and a 0.04-acre mitigation area adjacent to the Poplar Creek channel within the Poplar Creek Golf Course.

Geology within the APE is comprised of reclaimed land and artificial fill. 38 Soils within the APE belong
to the Urban land-Orthents series, which is found on areas that were once a part of the San Francisco Bay and adjacent tidal flats that have been filled. Historically, this soil series was used for homesite, urban, and recreational development.39
Pursuant to State CEQA Guidelines Section 15064.5, the City’s General Plan was consulted to identify any National, State, or Local historical landmarks with the project site. Review of historic registers and inventories indicate that three (3) listed historical resources are located within 0.25 mile of the APE. These resources are two (2) buildings that have no potential to extend into the APE and one (1) shellmound. The NWIC base maps and files showed that there are no resources rec orded

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 45 within the APE. Based on the environmental setting there is a very low potential for prehistoric sites to be found within the APE.

Based on criteria derived from Meyer and Rosenthal , the potential for the presence of surface prehistoric and buried archaeological sites throughout the project site is very low.40 Based on review of historical maps and aerial photos, the golf course where the APE is located was built in 1933, during the Great Depression by the Works Progress Administration (WPA). It has the potential to be eligible for the National Register under criterion A (see Discussion of Impacts below).

Regulatory Setting
Federal and state criteria have been established for the determination of historical resource significance as defined in Nati onal Register (NR) criteria contained in National Register Bulletin 16 (U.S. Department of the Interior 1986:1) and for the purposes of CEQA under Section 5024.1(g) of the Public Resource Code and Section 15064.5 of the State CEQA Guidelines.

National Historic Preservation Act
The National Historic Preservation Act ( NHPA) applies to certain projects undertaken requiring approval by federal agencies. Property owners, planners, developers, as well as State and local agencies are responsible for complying with NHPA’s requirements regarding the identification and treatment of historic and prehistoric cultural resources. Under NHPA, cultural resources must be evaluated to determine their eligibility for listing in the NR. If an archaeological resource is determined ineligible for listing on the NR, then the resource is released from management responsibilities and a project can proceed without further cultural resource considerations.

The project site was evaluated for eligibility for listing on the NRHP per the four (4) criteria established in 36 CFR 60.4. As set forth in Title 36, Part 63 of the Code of Federal Regulations, for a cultural resource to be deemed significant under the NHPA and thus eligible for listing on the NR, it must meet at least one (1) of the following criteria:
(A) Associated with events that have made a significant contribution to the broad patterns of our history; or
(B) Associated with the lives of persons significant in our past; or (C) Embodies distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or
(D) Yielded, or may be likely to yield, information important in prehistory or history.

These aspects are as follows: Location, Design, Setting, Materials, Workmanship, Feeling, and Association.

California Environmental Quality Act
CEQA applies to certain project s undertaken requiring approval by State and/or local agencies.

Under CEQA, cultur al resources must be evaluated to determine their eligibility for listing in the California Register of Historic Resources (CRHR). If a cultural resource is determined ineligible for listing on the CRHR the resource is released from management responsibili ties and a project can proceed without further cultural resource considerations.

As set forth in Section 5024.1(c) of the Public Resources Code for a cultural resource to be deemed “important” under CEQA and thus eligible for listing on CRHR, it must meet at least one (1) of the following criteria:
(1) Associated with events that have made a significant contribution to the broad patterns of California History and cultural heritage; or
(2) Associated with the lives of persons important to our past; or (3) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possess high artistic value; or
(4) Has yielded or is likely to yield, information important to prehistory or history.

Discussion of Impacts
a) Less than Significant Impact. Based on the findings of the Tom Origer & Associates Report, the Poplar Creek Golf Course has the potential for inclusion on the National Register and California Register of Historic Resources due to the fact that it is associated with events that have made a significant contribution to the broad patterns of local or regional history, or the cultural heritage of California or the United States. The Poplar Creek Golf Course was constructed in 1933 by the WPA as a project to help alleviate the financial impact of the Great Depression. The golf course has been in operation since that time and as such is also a piece of the cultural heritage of the area.

Although the proposed project would be taking place within a site that has the potential for inclusion in the historic databases, the proposed activities would not cause a substantial adverse change to the resource. The proposed project would install a trash capture device within Poplar Creek, which flows through the golf course, but is not part of the golf course.

Additionally, the area where the trash capture device would be installed is outside out the field of play. The trash capture device would be installed in an area where only maintenance and city workers have access.

The stream enhancement area would be located more directly within the playable golf course area. The location area was selected for its remoteness on the course; however, it is possible that historic resources could be encountered during planting. Implementation of M itigation DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 105 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 47 Measures CULT-1 in Impact b) below would ensure that any impacts to these resources would remain less than significant.
b) Less than Significant Impact with Mitigation Incorporated. The project site has a very low sensitivity for archaeological resources. Historically, the project site was part of the waters of the San Francisco Bay. As such, there is a low sensitivity for encountering either prehistoric or historic -era archaeological resources. Additionally, al l p roposed project improvements would occur within existing disturbed areas and no improvements would require additional large-scale excavation. The previous construction activity would likely have reduced or eliminated the significance of archaeological resources if they were encountered.

In the unlikely event that archaeological resources are found during project activities, the following mitigation measure will ensure that it is preserved:

Impact CULT-1: Implementation of the project could result in impacts to buried prehistoric or historical archaeological deposit.

Mitigation Measure CULT -1: If previously unidentified historic resources are encountered during project implementation, the contractor shall avoid altering the materials and their stratigraphic context. A qualified professional archaeologist shall be contacted to evaluate the situation. Project personnel should not collect cultural resources. Historic resources include stone or abode foundations or walls; structures and remains with square nails; and refuse deposits or bottle dumps, often located in old wells or privies. The City or its contractor shall comply with California Health and Safety Code Section 7050.5 and California Public Resources Code Sections 5097.5, 5097.9 et seq., regarding the discovery and disturbance of cultural materials, should any be discovered during project construction.

If archaeological remains are uncovered, work at the place of discovery shall be halted immediately until a qualified archaeologist can evaluate the finds (§15064.5 [f]). Prehistoric archaeological site indicators include obsidian and chert flakes and chipped stone tools; grinding and mashing implements (e.g., slabs and handstones, and mortars and pestles); bedrock outcrops and boulders with mortar cups; and locally darkened midden soils. Midden soils may contain a combination of any of the previously listed items with the possible addition of bone and shell remains, and fire affected stones. Historic period site indicators generally include fragments of glass, ceramic, and metal objects; milled and split lumber; and structure and feature remains such as building foundations and discrete trash deposits (e.g., wells, privy pits, dumps).
c) Less than Significant Impact with Mitigation Incorporated. There are no formal cemeteries on the site, nor are human remains likely to exist on the site. However, there is the potential for the discovery of human remains on the project site during ground disturbance activities. Implementation of Mitigation Measure CULT-2 would allow for timely identification, analysis, and documentation of any human remains. Therefore, impact related to the destruction of human remains would be mitigated to a less-than-significant level.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 48 Impact CULT -2: Project construction activities coul d result in impacts to previous undiscovered human remains.

Mitigation Measure CULT -2: If human remains are discovered during excavation and/or grading of the site, all activity within a 50-foot radius of the find shall be stopped. The San Mateo County Coroner shall be notified and make a determination as to whether the remains are of Native American origin or whether an investigation into the cause of death is required. If the remains are determined to be Native American, the Coroner will notify the Native American Heritage Commission (NAHC) immediately. Once the NAHC identifies the most likely descendants, the descendants will make recommendations regarding proper burial, which will be implemented in accordance with Section 15064.5(e) of the CEQA Guidelines.

Environmental Setting
Energy usage is typically quantified using the British thermal unit (BTU). As a point of reference, the approximate amount of energy contained in common energy sources are as follows: gasoline, 115,000 BTUs per gallon; diesel, 138,500 BTUs per gallon; natural gas, 21,000 BTUs per pound (lb); electricity, 3,414 BTUs per kilowatt-hour (kWh).41
Total energy usage in California was 7,967 trillion BTUs in 2018, which equates to an average of 202 million BTUs per capita. Of California’s total energy usage, the breakdown by sector is

39.4 percent transportation, 23.1 percent industrial, 18.7 percent residential, and 18.8 percent commercial. Natural gas is California’s primary source of electric power, followed by nonhydroelectric renewables, nuclear, and hydroelectric sources. 42 Given the nature of the proposed project, the only use of energy would occur via construction vehicle fuel and fuel utilized by device maintenance vehicles . The trash capture device would not require any energy to operate and would not tie into the City of San Mateo utility system. All construction would occur during daylight hours. No artificial light sources would be necessary.

Regulatory Setting
Federal and state agencies regulate energy use and consumption through various means and programs. At the federal level, the United States Department of Transportation (DOT), the United States Department of Energy (DOE), and U.S. EPA are three (3) federal agencies with substantial influence over energy policies and programs. Generally, federal agencies influence and regulate transportation energy consumption through establishment and enforcement of fuel economy

At the state level, the California Public Utilities Commission ( CPUC) and the California Energy Commission (CEC) are two (2) agencies with authority over different aspects of energy. The CPUC regulates privately owned utilities in the energy, rail, telecommunications, and water fields. The CEC collects and analyzes energy-related data, prepares statewide energy policy recommendations and plans, promotes, and funds energy efficiency programs, and adopts and enforces applianc e and building energy efficiency standards. California is exempt under federal law from rules that otherwise would preempt setting state fuel economy standards for new on-road motor vehicles. Some of the more relevant federal and state energy-related laws and plans are discussed below.

Senate Bill (SB) 1389 requires the CEC to prepare a biennial integrated energy policy report that assesses major energy trends and issues facing the State’s electricity, natural gas, and transportation fuel sectors and provides policy recommendations to conserve resources; protect the environment; ensure reliable, secure, and diverse energy supplies; enhance the State’s economy; and protect public health and safety.

The 2020 Integrated Energy Policy Report is the most recent update. The State’s energy system includes energy extraction, transport, conversion (such as combusting natural gas in power plants to generate electricity or producing gasoline and diesel from crude oil in refineries), and consumption for services (such as electricity for lighting, natural gas use in homes and buildings for space and water heating, pumping water to communities and crops, and gasoline and diesel to fuel cars and trucks), as well as electricity from out of-State plants serving California. In 2019, the State consumed approximately 3.8 billion gallons of diesel.

Federal
Energy Policy Act of 2005
Passed by Congress in July 2005, the Energy Policy Act includes a comprehensive set of provisions to address energy issues. The act includes tax incentives for the following: energy conservation improvements in commercial and residential buildings; fossil fuel production and clean coal facilities; and construction and operation of nuclear power plants, among other things. Subsidies are also included for geothermal, wind energy, and other alternative energy producers. It directs the DOE to study and report on alternative energy sources such as wave and tidal power and includes funding for hydrogen research. The Act also increases the amount of ethanol required to be blended with gasoline and extends daylight saving time (to begin earlier in spring and end later in fall) to reduce lighting requirements. It also requires the federal vehicle fleet to maximize use of alternative fuels.

The Act further includes provisions for expediting construction of major energy transmission DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 109 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 51 corridors, such as high-voltage power lines, and fossil fuel transmission pipelines. These are just a few examples of the provisions contained in the Act.43
Energy Independence and Security Act of 2007
Signed into law in December 2007, this broad energy bill included an increase in auto mileage standards, and also addressed biofuels, conservation measures, and building efficiency. The U.S.

EPA administers the Corporate Average Fuel Economy (CAFE) program, which determines vehicle manufacturers’ compliance with existing fuel economy standards. The bill amended the CAFE standards to mandate significant improvements in fuel efficiency (i.e., average fleet wide fuel economy of 35 miles per gallon (mpg) by 2020, versus the previous standard of 27.5 mpg for passenger cars and 22.2 mpg for light trucks).
44 Another provision includes a mandate to increase use of ethanol and other renewable fuels by 36 billion gallons by 2022, of which 21 million gallons is to include advanced biofuels, largely cellulosic ethanol, that have 50 to 60 percent lower greenhouse gas ( GHG) emissions. The bill also includes establishment of a new energy block grant program for use by local governments in implementing energy-efficiency initiatives, as well as a variety of green building incentives and programs, among other things.
45 State
Energy Action Plan
In 2003, the three (3) key energy agencies in California—the CEC, the California Power Authority (CPA), and the CPUC— jointly adopted an Energy Action Plan (EAP) that listed goals for California’s energy future and set forth a commitment to achieve these goals through specific actions. In 2005, the CPUC and the CEC jointly prepared the EAP II to identify the further actions necessary to meet California’s future energy needs. The EAP II describes the priority sequence for actions to address increasing energy needs, also known as “loading order.” The loading order identifies energy efficiency and demand response as the state’s preferred means of meeting growing energy needs.

After cost-effective efficiency and demand response, the state is to rely on renewable sources of power and distributed generation, such as combined heat and power applications. To the extent that efficiency, demand response, renewable resources, and distributed generation are unable to satisfy increasing energy and capacity needs, the EAP II supports the use of clean and efficient fossil fuel-fired generation.

In 2008, the CPUC and CEC released an Energy Action Plan Update using information and analysis prepared for the Energy Commission’s 2007 Integrated Energy Policy Report (IEPR) . The Update

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 52 was partially written in response to the California Global Warming Solutions Act of 2006 (discussed below), intended to keep the EAP I and EAP II process alive while capturing changes in the policy landscape and describing intended activities to accomplish those policies. The focus areas included:
energy efficiency, demand response, renewable energy, electricity reliability and infrastructure, electricity market structure, natural gas supply and infrastructure, research and development, and climate change.
46 The EAP identifies key actions to be taken in all these areas in order to meet the state’s growing energy requirements. The plan recommendations are implemented by the governor through executive orders, by the legislature through new statutes, and by the responsible state agencies through regulations and programs.

Title 24 (California Energy Code)
The California Energy Code (Title 24, Part 6, of the California Code of Regulations, California’s Energy Efficiency Standards for Residential and Nonresidential Buildings), provides energy conservation standards for all new and renovated commercial and residential buildings constructed in California. The provisions of the California Energy Code apply to the building envelope, space-conditioning systems, and water -heating and lighting systems of buildings and appliances; they also give guidance on construction techniques to maximize energy conservation. Minimum efficiency standards are given for a variety of building elements, including appliances; water and space heating and cooling equipment; and insulation for doors, pipes, walls, and ceilings. The CEC adopted the 2005 changes to the Building Efficiency Standards, which emphasized saving energy at peak periods and seasons, and improving the quality of installation of energy-efficiency measures.

It is estimated that implementation of the 2005 Title 24 standards have resulted in an increased energy savings of 8.5 percent relative to the previous Title 24 standards. Compliance with Title 24 standards is verified and enforced through the local building permit process. 47 The 2008 Title 24
Standards, which had an effective date beginning August 1, 2009, include added provisions that require, for example, “cool roofs” on commercial buildings; increased efficiency in heating, ventilating, and air conditioning systems; and increased use of skylights and more efficient lighting systems.
48 Title 24 Standards were further updated with the 2013 Building Energy Efficiency Standards, which are estimated to lead to 25 percent less energy consumption for residential buildings and 30 percent savings for nonresidential buildings over 2008 Energy Standards. 2013 standards, which updated codes for lighting, space heating and cooling, ventilation, and water heating, took effect on July 1, 2014.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 53 California Green Building Standards Code
All new construction must adhere to the California Green Building Standards Code (CCR, Title 24, Part 11) in place at the time of construction. As an example, the 2013 Title 24 California Green Building Standards, referred to as CALGreen:
• Sets a threshold of a 20 percent reduction in indoor water use and includes voluntary goals for reductions of 30 percent, 35 percent, and 40 percent. • Requires separate meters for indoor and outdoor water use at nonresidential buildings; and at those sites, irrigation systems for larger landscaped areas must be moisture-sensing. • Calls for 50 percent of construction waste to be diverted from the landfills and lists higher, voluntary diversion amounts of 65 percent to 75 percent for new homes, and 80 percent for commercial construction.
• Mandates inspections of energy systems -- such as the heat furnace, air conditioning, and mechanical equipment -- for nonresidential buildings that are larger than 10,000 square feet to "ensure that all are working at their maximum capacity according to design efficiencies." • Requires that paint, carpet, vinyl flooring, particle board, and other interior finish materials be low emitting in terms of pollutants.

California Global Warming Solutions Act of 2006
In September 2006, the governor signed AB 32, the Global Warming Solutions Act of 2006, which mandates that California’s GHG emissions be reduced to 1990 levels by 2020. The act directs the California EPA to work with state agencies to implement a cap on GHG emissions (primarily carbon dioxide [CO
2]) from stationary sources of such as electric power generation facilities, and industrial, commercial, and waste-disposal sectors. Since CO2 emissions are directly proportional to fossil fuel consumption, the cap on emissions is expected to have the incidental effect of forcing a reduction in fossil fuel consumption from these stationary sources. Specifically, AB 32 directs the California EPA to work with other state agencies to accomplish the following: 1) promulgate and implement GHG emissions cap for the electric power, industrial, and commercial sectors through regulations in an economically efficient manner; 2) institute a schedule of greenhouse gas reductions; 3) develop an enforcement mechanism for reducing GHG; 4) establish a program to track and report GHG emissions.
49 Senate Bill 32
Enacted in 2016, SB 32 codifies the 2030 GHG emissions reduction goal of Executive Order B-30--15 by requiring the California Air Resources Board ( CARB) to ensure that statewide GHG emissions are reduced to 40 percent below 1990 levels by 2030. Similar to AB 32, a reduction in GHG emissions typically corresponds with a reduction in energy usage as the bulk of GHGs result

SB 32 was coupled with a companion bill: AB 197. 50 Designed to improve the transparency of CARB’s regulatory and policy-oriented processes, AB 197 created the Joint Legislative Committee on Climate Change Policies, a committee with the responsibility to ascertain facts and make recommendations to the Legislature concerning statewide programs, policies and investments related to climate change. AB 197 also requires CARB to make certain GHG emissions inventory data publicly available on its website; consider the social costs of GHG emissions when adopting rules and regulations designed to achieve GHG emission reductions; and include specified information in all Scoping Plan updates for the emission reduction measures contained therein.

Discussion of Impacts
a) Less than Significant Impact. The proposed project would require the use of diesel and other fuels for trucks and equipment during construction, but these activities would be short-term and completed as efficiently as possible for practical and financial reasons. The operation of the project would consume energy from maintenance trucks that would remove accumulated trash from the capture device two (2) to three (3) times a year and maintain the stream enhancement area. Given the important pollutant control functions of the trash capture device, the relatively minor amount of energy used to maintain the device is not wasteful, inefficient, or unnecessary . Therefore, the trash capture device would result in less-than-significant impacts.
b) Less than Significant Impact . The project would install a passive trash capture device in Poplar Creek and enhance vegetation along the creek’s banks. As described above, the proposed project would not result in wasteful, inefficient, or unnecessary consumption of energy during any project phase. Electricity demands on-site would be substantially the same as under existing conditions, will not increase over time, and will be adequately served by the current provider. Therefore, the project would not conflict with state or local plan for renewable energy or energy efficiency. Impacts would be less-than-significant.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 56 Environmental Setting
Regional Setting
The project site lies within the Coast Ranges geomorphic province of California. Regional topography within the Coast Ranges province is characterized by northwest-southeast trending mountain ridges and intervening valleys that parallel the major geologic structures, including the San Andreas Fault System. The province is also generally characterized by abundant landsliding and erosion, owing in part to its typically high levels of precipitation and seismic activity.

Earthquake Hazards
Earthquakes are the product of the build-up and sudden release of strain along a “fault” or zone of weakness in the earth's crust. Stored energy may be released as soon as it is generated, or it may be accumulated and stored for long periods of time. Faults are seldom single cracks in the earth's crust but are typically comprised of localized shear zones which link together to form larger fault zones. Within the Bay Area , faults are concentrated along the San Andreas fault system, which extends nearly 700 miles along a northwest trend from Mexico to offshore northern California. The movement between rock formations along either side of a fault may be horizontal, vertical, or a combination and is radiated outward in the form of energy waves. The amplitude and frequency of earthquake ground motions partially depends on the material through which it is moving. The earthquake force is transmitted through hard rock in short, rapid vibrations, while this energy becomes a long, high-amplitude motion when moving through soft ground materials, such as Bay Mud.

Liquefaction
Liquefaction occurs when a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress, such as seismic shaking, which causes a solid to behave like a liquid. Soils susceptible to liquefaction are saturated, loose, granular deposits. Liquefaction can result in flow failure, lateral spreading, ground movement, settlement, and other related effects.

Buried pipelines embedded within liquefied soils may also experience uplift due to buoyancy.

Landslides
Landslides are frequently triggered by strong ground motions. They are an important secondary earthquake hazard. The term landslide includes a wide range of ground movement, such as rock falls, deep failure of slopes, and shallow debris flows. Landslides from seismic activity are a very low risk at the project site given its flat topography and general lack of slopes, cliffs, or flowing water.

An “active” fault is one that shows displacement within the last 11,000 years (i.e., Holocene) and has a reported average slip rate greater than 0.1 millimeters w per year. The California Division of Mines and Geology has mapped various active and inactive faults in the region. The nearest known active DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 115 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 57 faults to the site are the San Andreas and Hayward Faults, which are approximately two (2) miles west and 14 miles northeast of the City of San Mateo respectively.51 Local Setting
The project site is located immediately west of San Francisco Bay . Work would occur within Poplar Creek, a concrete-lined, intermittent channel, and on surrounding golf course lands. Regional geologic mapping indicates that the site is underlain by artificial fill over Bay Mud. 52 The site is underlain by urban land-Orthents, reclaimed complex, 0 to 2 percent slopes soils. 53 These soils are characteristic of artificial fill.

The project site, like all properties in the San Francisco Bay area, is situated in a seismically active area. In the San Francisco Bay Area, the San Andreas fault system includes the San Andreas, Hayward, Calaveras, and other related faults in the San Francisco Bay area. According to the U.S.

Geological Survey, there is a 62 percent chance of at least a magnitude 6.7 (or greater) earthquake in the San Francisco Bay region between 2003 and 2032.
54 The project site is not located within a State of California Earthquake Fault Zone for active faulting and no active faults are mapped on the property. The San Andreas Fault is located approximately

3.9 miles southwest of the site whereas the Hayward Fault is located approximately 14.4 miles to the northeast.55
Discussion of Impacts

a-ii) Less than Significant Impact. There would be potential for “violent” seismic ground-shaking at the project site according to ABAG’s Resilience Program hazards map.57 The project site proximity to two (2) active bay site faults (San Andreas and Hayward) leaves it vulnerable to ground shaking, which is common in the Bay Area. The proposed project would not create a need or opportunity for people to reside on-site and thus be exposed to such ground shaking long-term. If an earthquake were to occur during the construction phase, it could create a risk for workers on-site, but under the obligation of the Occupational Safety and Health Act (OSHA), construction workers would be trained to take the necessary precautions to maintain worker safety in the event of an earthquake. The only risk created to workers on-site during the operational phase would be during trash capture device maintenance and stream enhancement area monitoring. Workers on-site would also be trained according to OSHA regulations. The trash capture device itself would be designed to conform to the most recent edition of the California Building Code with flexible connections and California Building Code (CBC) design features. Therefore, the impacts related to this topic would be less than significant.
a-iii) Less than Significant Impact. According to ABAG’s Resilience Program hazards map, the project site has a very high susceptibility to liquefaction. 58 The project would conform to the
standard engineering and building practices and techniques specified in the CBC. The project plan would meet the requirements of appropriate Site Development Codes, as adopted by the City of San Mateo. In addition, the proposed trash capture device would be constructed only at a depth of 5.5 inches under the existing concrete channel, which would be at the aggregate base that is used to support the channel.59 Therefore, the existing aggregate base would support the trash capture device and would not be subject to hazards from liquefaction.

Impacts would be less than significant.
a-iv) Less than Significant Impact. T he project is subject to all f ederal, state, and local regulations and standards for seismic conditions, including the CBC, and would be designed to conform to all building requirements. According to ABAG’s Resilience Program hazards map, the project site is located on flat land and is not susceptible to landslides. Given the low

C onstruction would involve limited soil disturbance during grading of the staging area, which could temporarily expose soils to wind and water erosion.

Additional soil disturbance would occur during planting of the stream enhancement area .

Plantings would be installed using hand tools or augers and would not disturb substantial topsoil areas. The project would not cause a substantial change to erosion and accretion patterns of the area long-term because the trash capture device installation and stream enhancement would not alter the existing drainage pattern of the area. Temporary construction impacts related to run-off during site grading would occur, but standard measures from the City of San Mateo Municipal and Site Development Codes as well as from the Regional Water Board’s Section 401 Water Quality Certification would be implemented to ensure impacts from runoff would remain less than significant. Additionally, there would be no disturbance of native topsoil, as construction activities would take place mainly within existing paved roads. In addition, the soil in the area is non-native fill material.

Impacts on soil would therefore be less than significant. c, d) Less than Significant Impact. The potential for geologic and soil hazards from unstable or expansive soils in the project site is considered low based on the geologic units, soil types, and flat topography discussed previously

60. The ground disturbance associated with the
proposed project would cause minimal soil disturbance and these actions would not result in substantial changes in topography, ground surface relief features, or geologic substructures.

The trash capture device itself would be integrated into the concrete lining of Poplar Creek and would not affect soil conditions. Furthermore, the project is subject to all Federal, State, and local regulations and standards for seismic conditions including CBC and would be designed to conform to all building requirements. The stream enhancement area would not substantially impact soil conditions. Therefore, the proposed project’ s impacts would not destabilize the soil or expose human life or structures to increased risk of on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse. Therefore, impacts would be less than significant.
e) No Impact. The project does not involve construction of septic tanks or alternative wastewater disposal systems. There would be no impact.
f) Less than Significant Impact. The project site consists of concrete-lined portions of Poplar Creek, surrounding previously disturbed areas, and golf course lands. Grading of the staging area and minimal concrete excavation would be required, but any disturbed areas would be non-native fill and are unlikely to contain any paleontological resources. The ground disturbance associated with the project would not change the topography or geologic

Environmental Setting
GHGs are recognized by wide consensus among the scientific community to contribute to global warming/climate change and associated environmental impacts. The major GHGs released from human activity are CO 2, methane, and nitrous oxide. 61 The primary sources of GHGs are vehicles (including planes and trains), energy plants, and industrial and agricultural activities (such as dairies and hog farms).

In the United States, the main source of GHG emissions is electricity generation, followed by transportation.
62 In California, however, transportation sources (including passenger cars, light-duty trucks, other trucks, buses, and motorcycles) are the largest contributors of GHG emissions. 63 The dominant GHG emitted is CO2, mostly from fossil fuel combustion.

In 2017, total CO2 emissions in the City of San Mateo were 541,960 metric tons (MT) CO2 equivalent (CO2e). This represents an 18 percent decrease relative to 2005 levels.64 The largest source of these emissions was on-road transportation.

On September 8, 2016, the governor signed SB 32 into law, extending AB 32 by requiring the State to further reduce GHG emissions to 40 percent below 1990 levels by 2030.

Senate Bill 97
SB 97, adopted in 2007, required the Governor’s Office of Planning and Research to develop CEQA guidelines “for the mitigation of greenhouse gas emissions or the effects of greenhouse gas emissions,” and the Resources Agency certified and adopted the amendments to the guidelines on December 30, 2009.

Local
2020 Climate Action Plan
In 2020, the City of San Mateo adopted its Climate Action Plan as a strategy to reduce greenhouse gas emissions, as directed by the City’s General Plan. The Climate Action Plan sets GHG emissions reductions targets and goals for 2020, 2030, and 2050 that are consistent with the overall state reduction targets. The 2020 plan is a direct update of the 2015 CAP and analyzes the progress that the City has made in meeting its GHG reduction targets as well as updates information to achieve more significant and long-term reductions. The C limate Action Plan presents a work plan and monitoring program for the City to track progress over time and maintain the status of the C limate Action Plan as a qualified GHG reduction strategy.

Discussion of Impacts
a) Less Than Significant Impact. GHG emissions from the project would be produced from construction-related equipment emissions. Based on the nature of the project and short duration of construction, GHG emissions resulting from construction activities would be both minor and temporary. While the project would have an incremental contribution to GHG emissions within the City and region, the individual project’s contribution is less than significant. During the operational phase, maintenance trucks would be utilized during trash removal activities approximately two (2) to three (3) times per year, which results in the emission of an incremental and negligible amount of GHGs. The project would not result in an increase in electricity usage as the trash rack would not use an electricity. The project would not involve the addition of any stationary equipment that would result in GHG emissions. For these reasons, the proposed project would result in a less than significant impact due to the generation of GHG emissions.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 63 b) Less Than Significant Impact. As described above, the proposed project would not result in substantial GHG emissions during the construction or operation phase. The proposed project would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing GHG emissions. The City of San Mateo met the 2020 AB 32 reducti on targets and has developed the CAP to track progress toward future targets. GHG emissions from off-road equipment and utility electrical usage are identified and planned for in the BAAQMD’s 2017 Clean Air Plan as well as the BAAQMD’s Source Inventory of Bay Area Greenhouse Gas Emissions . A primary objective of the 2010 Clean Air Plan is to reduce greenhouse gas emissions to 1990 levels by 2020 and 40 percent below 1990 levels by 2035. The project would generate emissions similar to existing conditions and, therefore, a less than significant impact would occur.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 65 Environmental Setting
A material is considered hazardous if it appears on a list of hazardous materials prepared by a federal, state, or local agency or if it has characteristics defined as hazardous by such an agency. A hazardous material is defined in Title 22, Section 66261.10 of the California Code of Regulations as a substance with physical, chemical, or infectious characteristics which may cause or contribute to mortality or illness or pose a threat to human health or the environment when mismanaged. Chemical and physical properties which may cause a substance to be considered hazardous include toxicity, ignitability, corrosivity, and reactivity.

Under Government Code Section 65962.5, the California Department of Toxic Substances Control (DTSC) maintains a list of hazardous substance sites. This list, referred to as the “Cortese List,” includes CALSITE hazardous material sites, sites with leaking underground storage tanks (LUSTs), and landfills with evidence of groundwater contamination. The SWRCB GeoTracker database similarly docume nts hazardous waste sites throughout the state but focuses on groundwater contamination. According to the Cortese List, there are no Federal superfund sites within five (5) miles of the proposed project. There is an active school investigation site located approximately

0.25-mile east of the project site.
65 GeoTracker lists 11 active sites within one (1) mile of the proposed project site, but project activities will not affect the cleanup of any active sites and vice versa. Four (4) of the sites are LUST cleanup sites. The remaining seven (7) sites are sites of former gas stations, heavy machinery lots, and dry cleaners, businesses where the daily operations contaminated the surrounding areas.
66 Discussion of Impacts
a) Less than Significant Impact. Project construction activities are expected to involve the routine transport, use, and disposal of hazardous materials (e.g., motor fuels , oils, and grease) that could pose a significant threat to human health or the environment if not properly managed. Although small amounts of these materials would be transported, used, and disposed of during project construction, these materials are typically used in construction projects and are not considered acutely hazardous. Workers who handle hazardous materials are required to adhere to health and safety requirements enforced by the federal OSHA and California Division of Occupational Safety and Health (Cal/OSHA). Hazardous materials must be transported to and from the project site in accordance with Resource Conservation and Recovery Act (RCRA) and U.S. DOT regulations. Hazardous materials must also be disposed of in accordance with RCRA regulations at a facility that is permitted to accept the waste. compliance with existing regulations is mandatory, project construction

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 66 is not expected to create a significant hazard to public health or the environment through the routine transport, use, or disposal of hazardous materials.

During project operation, vacuum trucks would be used to remove accumulated debris from the trash capture device that would be placed within Poplar Creek. It is not anticipated that the device would capture hazardous wastes, as these materials are not regularly encountered in stormwater systems. The vacuum trucks would remove the trash from the device and transport it to a solid waste facility. The transport of refuse would adhere to all applicable local, state, and federal regulations listed above. As a result, impacts related to the routine transport, use, or disposal of hazardous materials during project construction and operation would be less than significant.
b) Less than Significant Impact. The proposed project would be installing a trash capture device within a concrete-lined, intermittent stream. In order to anchor the device within the stream bed, the concrete must be removed and replaced around the device. It is possible that a skidsteer or excavator will be used within the channel to complete the concrete work.

This heavy machinery would utilize motor fuels that could pose a significant threat to human health or the environment if not properly managed. However, this work would occur after the site is dewatered to reduce the likelihood of contamination from hazardous materials entering the waterway and unnec essary increases to turbidity. Additionally, all construction best management practices discussed in the project description would be followed. Therefore, impacts would be less than significant.
c) No Impact. There are no schools within one-quarter mile of the project site. Therefore, there would be no impacts on schools.
d) No Impact. The provisions of Government Code Section 65962.5 require the State Water Resources Control Board, Department of Toxic Substances Control, California Department of Health Services, and California Department of Resources Recycling and Recovery to submit information to the California Environmental Protection Agency pertaining to sites that were associated with solid waste disposal, hazardous waste disposal, and/or hazardous materials releases. The compilation of hazardous materials release sites that meet criteria specified in Section 65962.5 of the California Government Code is known as the Cortese List.

There are currently no hazardous materials release sites within the project site that meet the criteria for inclusion on the Cortese List. Therefore, the project would have no impacts related to development on a hazardous materials release site included on the Cortese List. e) Less than Significant Impact. The project site is located approximately 2.7 miles southwest of the San Francisco International Airport and falls within the Compr ehensive Airport Land Use Compatibility Plan for the Environs of San Francisco International Airport plan area. The noise contour map from the Airport Land Use Compatibility Plan shows that the project site DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 125 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 67 is not significantly affected by noise from the airport.67 Therefore, there would be no hazards as a result of excessive noise due to proximity to the airport. Additionally, the proposed project does not plan to construct any structures that would visually impair the landscape in a way that would impact the airport’s approach or departure zones. The project would have no impacts on the navigable airspace of public use airports and would not result in a safety hazard for people residing or working in the project site. Impacts would be less than significant.
f) No Impact. The proposed project is located within and adjacent to a creek within a City operated golf course. There would be no road closures associated with this project.

Therefore, construction of the proposed project would not block or impair any existing emergency evacuation routes. There would be no impact.
g) No Impact. The project site is within and adjacent to a creek and is surrounded by managed open space and paved urbanized uses. There are no wildfire hazard areas within the City of San Mateo.
68 Therefore, the project would have no impact related to wildland fire hazards.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 69 The following analysis of hydrology and water quality impacts is based on a Hydraulic Impact Study conducted by Schaaf & Wheeler.

Environmental Setting
The project site is located in the San Mateo Plai n Groundwater Basin and discharges to the San Francisco Bay.69 The San Mateo Groundwater Basin encompasses 60,057 acres. The basin consists of mostly urbanized lands throughout the City. The City of San Mateo delineates seven (7) watersheds within the city, the project site falling within the North Shoreview Pump Stat ion Watershed.70 Groundwater levels at the project site are approximately 306 feet deep.71 Project work would occur within Poplar Creek. Poplar Creek is an intermittent, concrete-lined stream that is part of the City’s stormwater management system. From Site 1, Poplar Creek continues in a northeasterly direction for approximately 3,000 feet past Stream Enhancement Site 2, at which time the channel becomes unlined and begins to flow in the southeasterly direction. This earthen channel conveys flow for approximately 700 feet before discharging into the open forebay of the Poplar Pump Station. Flow from the forebay enters the pump station intake and is discharged through the earthen flood control levee into San Francisco Bay.

The project site is covered with pervious surfaces such as ruderal grasses in the proposed staging area. At Stream Enhancement Site 2, the site is developed golf course land with existing drainage flowing into Poplar Creek . According to the Federal Emergency Management Agency (FEMA) Federal Insurance Rate Maps (FIRM), the project site is in Flood Zone AE, which is defined as an area within the 100-year flood zone where a base flood elevation has been determined. 72 Regulatory Setting
The federal Clean Water Act (CWA) Section 402, promulgated by rules developed by the U.S. EPA in 1990, establishes the NPDES stormwater program. The program requires that urban stormwater runoff pollution of the nation’s water be regulated for Municipal Separate Storm Sewer Systems (MS4s). The San Francisco Bay Regional Water Board issued one (1) Municipal Regional Stormwater NPDES Permit (MRP) in 2015 covering MS4s that serve populations of 100,000 or greater.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 70 The City of San Mateo is part of the San Mateo Countywide Water Pollution Prevention Program (SMCWPPP) which was established in 1990 to reduce the pollution carried by stormwater into local creeks, San Francisco Bay, and the Pacific Ocean. The program is a partnership of the City/County Association of Governments (C/CAG) which is comprised of each incorporated city and town within San Mateo County. The C/CAG shares a NPDES permit.

Discussion of Impacts
a) Less than Significant Impact with Mitigation Incorporated. Under Provision C.10 of the City’s Municipal Regional Stormwater NPDES perm it, the City of San Mateo is required to reduce trash loads from MS4s by 100 percent by July 1, 2025. The trash capture device proposed by this project would be used to reduce trash loads from approximately 333 acres of San Mateo’s upstream storm drain sys tem, approximately 3.3 acres of Caltrans ’ STGA, and approximately 15.9 acres of Caltrans ROW. This would have a positive impact on water quality during operation and would align with water quality standards.

Construction activities would require ground disturbance for saw-cutting into the creek bed, trash capture device installation, staging area grading, and stream enhancement planting.

Two (2) cofferdams would be installed in Poplar Creek prior to in stream work to facilitate dewatering of the project site prior to construction. In addition, the project would be required to implement mitigation measure HYDRO -1 ensure minimal impacts to water quality during in-channel work . Standard construction measures recommended by the San Mateo Countywide Water Pollution Prevention Program would be implemented to minimize pollutants carried from the project site in runoff. Water quality impacts during construction would therefore be less than significant with implementation of Mitigation Measure HYDRO-1 and adherence to applicable regulations , and operational water quality impacts would improve current baseline conditions.

Impact HYDRO-1: Project construction during in-channel work would have the potential to impact water quality.

Mitigation Measure HYDRO-1: The City shall incorporate the following practices into the construction documents to be implemented by the project contractor:
• During channel dewatering, all water pumped out of the work area would be collected in a settling tank and undergo turbidity testing before being discharged back in the channel. The settling tank would be up to 10,000 gallons in size depending on the results of water flow testing at the time of construction and would be located in the designated staging area.
• Equipment fueling and maintenance would occur off-site. • Fiber rolls would be installed between the staging area and the channel to prevent runoff of sediment into the channel . Rolls will be inspected and maintained on a weekly basis.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 71 • Hazardous waste spill prevention and stockpiling methods will be implemented according to California Stormwater Quality Association (CASQA) best management practices.
b) No Impact. The project would not require use of groundwater supplies or affect groundwater recharge in the area. The project would not install any new impervious surfaces. The project would remove and replace the concrete creek bed of Poplar Creek in order to install the trash capture device. There will be no increase in impervious surfaces. There would be no impact. c-i-iii) Less than Significant Impact. The proposed project would not result in substantial erosion, increase the rate or amount of surface runoff, or create or contribute to runoff that would exceed the capacity of the current system. The project would remove and replace the concrete lining of Poplar Creek in order to install the trash capture device, but there would be no net increase in impervious surfaces. The project would not cause a substantial change to the erosion and accretion patterns long-term because project activities would not alter the existing drainage pattern of the area. The stream enhancement area might prevent long term erosion; however, the area is already very well managed and does not contribute to erosion.

Temporary construction impacts related to run-off from grading could occur, but standard measures from the San Mateo Countywide Water Pollution Prevention Program and from the State Water Board’s General Permit would be implemented to ensure impacts from runoff would remain less than significant. Impacts would be less than significant. c-iv) Less than Significant Impact. A Hydraulic Impact Study was conducted by Schaaf & Wheeler to determine the impacts of installing the trash capture device within Poplar Creek.

Their report determined that the installation of the device at the decided upon location would result in between three (3) and one (1) foot of head loss in the stormwater system. Despite this loss, the report concluded that the addition of the trash capture device into the creek channel would not impede flood flows. There would be a less than significant impact. d) Less than Significant Impact. Seiche and tsunami are short duration, earthquake-generated water waves in large, enclosed bodies of water and the open ocean, respectively. Mudflows typically occur on steep slopes where vegetation is not sufficient to prevent rapid erosion. The project site is located in a flood hazard area (Zone AE). The project site is not located in a tsunami or seiche inundation area. 73 The purpose of the
proposed project is to i nstall a trash capture device that would remove pollutants from surfaces waters. Due to the design of the device, even if a flood were to occur pollutants would not be released during device operation. The stream enhancement area would add native vegetation to the project site and would not increase pollutant concentrations. During construction, the project would comply with the best management practices established by

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 77 Discussion of Impacts
a) No Impact. The project involves the installation of a trash capture device within a concrete- lined, intermittent stream and stream enhancement along the edge of Poplar Creek. All proposed work would occur within previously developed areas of a developed and maintained park. The project would not physically divide an established community. No impacts would occur.
b) Less than Significant Impact. The project would have a signific ant impact if it were to conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect. The project is subject to several local policies, plans, and regulations, as described above in the R egulatory Setting. The primary objective of the proposed project is to install a trash capture device within Poplar Creek and enhance native vegetation along the creek’s edge. The installation of the device and the enhancement of native vegetation are consistent with General Plan Policies LU -4.4.5, LU-8.9, UD-1.2, and C/OS-2.2. As a result of inserting a device within the creek channel, stormwater flow could be disrupted. The Hydraulic Impact Study completed for this project evaluated the hydraulic conditions of the creek and ensured that the trash capture device would be placed in the best possible location to avoid negative impacts to hydraulic flow, consistent with Policy C/OS-2.3 of the General Plan. The best management practices set forth in the Project Description would ensure that project work would minimize negative impacts to air and water quality caused by construction activities near and within the creek channel. These best management practices would be consistent with Policies LU -8.9 and C/OS -2.6. The project would not conflict with the City of San Mateo General Plan or other applicable land use plans or policies.

Impacts would be less than significant.

Environmental Setting
Noise is generally defined as sound that is loud, disagreeable, or unexpected. Sound, as described in more detail below, is mechanical energy transmitted in the form of a wave because of a disturbance or vibration.

There are several methods of characterizing sound. The most common in California is the A-weighted sound level or dBA. This scale gives greater weight to the frequencies of sound to which the human ear is most sensitive. Because sound levels can vary markedly over a short period of time, different types of noise descriptors are used to account for this variability. Typical noise descriptors include maximum noise level (L
max), the energy -equivalent noise level (L eq), and the day-night average noise level (Ldn). The Ldn noise descriptor is commonly used in establishing noise exposure guidelines for specific land uses. For the energy-equivalent sound/noise descriptor called Leq the most common averaging period is hourly, but L eq can describe any series of noise events of arbitrary duration.

Although the A-weighted noise level may adequately indicate the level of environmental noise at any instant in time, community noise levels vary continuously. Most environmental noise includes a conglomeration of noise from distant sources which create a relatively steady background noise in which no particular source is identifiable.

Since the sensitivity to noise increases during the evening hours, 24-hour descriptors have been developed that incorporate artificial noise penalties added to quiet-time noise events. The Day/Night DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 138 of 662

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 80 Average Sound Level, L dn (sometimes also referred to as DNL), is the average A -weighted noise level during a 24-hour day, obtained after the addition of 10 dB to noise levels measured in the nighttime between 10:00 p.m. and 7:00 a.m. The Community Noise Equivalent Level (CNEL) is a 24-hour A-weighted noise level from midnight to midnight after the addition of five (5) dBA to sound levels occurring in the evening from 7:00 p.m. to 10:00 p.m. and after the addition of 10 dBA to sound levels occurring in the night between 10:00 p.m. and 7:00 a.m.

Construction Noise
Noise impacts resulting from construction depend on the noise generated by various pieces of construction equipment, the timing and duration of noise generating activities, the distance between construction noise sources and noise sensitive receptors and shielding. Construction activities for individual projects are typically carried out in stages. During each stage of construction, there would be a different mix of equipment operating. Construction noise impacts primarily result when construction activities occur during noise-sensitive times of the day (e.g., early morning, evening, or nighttime hours), the construction occurs in area s immediately adjoining noise-sensitive land uses, or when construction lasts over extended periods of time. Where noise fr om construction activities exceeds 60 dBA L
eq and exceeds the ambient noise environment by at least five (5) dBA L eq at noise-sensitive uses in the project vicinity for a period exceeding one (1) year, the impact would be considered significant.

Construction Vibration
Construction operations are potential sources of substantial ground vibration depending on the distance from sensitive receptors, and the type of construction. Ground vibration from construction may consist of rapidly fluctuating motions or waves, which are also measured in decibels. The abbreviation “VdB” is used in this document for vibration decibels to reduce confusion with sound decibels.

Typical background vibration levels in residential areas are usually 50 VdB or lower, well below the threshold of perception for most humans. Perceptible vibration levels inside residences are attributed to the operation of heating and air conditioning systems, door slams and foot traffic. Construction activities, train operations, and street traffic are some of the most common external sources of vibration that can be perceptible inside residences.

Sound is technically described in terms of amplitude (loudness) and frequency (pitch). The standard unit of sound amplitude measurement is the dec ibel (dB). The decibel scale is a logarithmic scale that describes the physical intensity of the pressure vibrations that make up any sound. The pitch of the sound is related to the frequency of the pressure vibration. Since the human ear is not equally sensitive to a given sound level at all frequencies, a special frequency -dependent rating scale has been devised to relate noise to human sensitivity. The dBA scale provides this compensation by discriminating against frequencies in a manner approximating the sensitivity of the human ear.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 81 Noise, on the other hand, is typically defined as unwanted sound. A typical noise environment consists of a base of steady “background” noise that is the sum of many distant and indistinguishable noise sources. Superimposed on this background noise is the sound from individual local sources.

These can vary from an occasional aircraft or train passing by to virtually continuous noise from, for example, traffic on a major highway.

Several rating scales have been developed to analyze the adverse effect of community noise on people. Since environmental noise fluctuates over time, these scales consider that the effect of noise upon people is largely dependent upon the total acoustical energy content of the noise, as well as the time of day when the noise occurs. Those that are applicable to this analysis are as follows:
• L
eq – A Leq, or equivalent energy noise level, is the average acoustic energy content of noise for a stated period of time. Thus, the Leq of a time-varying noise and that of a steady noise are the same if they deliver the same acoustic energy to the ear during exposure. For evaluating community impacts, this rating scale does not vary, regardless of whether the noise occurs during the day or the night.
• L
max – The maximum instantaneous noise level experienced during a given period of time. • Lmin – The minimum instantaneous noise level experienced during a given period of time. • CNEL – The Community Noise Equivalent Level is a 24-hour average Leq with a 5 dBA “weighting” during the hours of 7:00 p .m. to 10:00 p .m. and a 10 dBA “weighting” added to noise during the hours of 10:00 p .m. to 7:00 a.m. to account for noise sensitivity in the evening and nighttime, respectively. The logarithmic effect of these additions is that a 60 dBA 24-hour Leq would result in a measurement of 66.7 dBA CNEL.

Noise environments and consequences of human activities are usually well represented by median noise levels during the day, night, or over a 24-hour period. For residential uses, environmental noise levels are generally considered low when the CNEL is below 60 dBA, moderate in the 60– 70 dBA range, and high above 70 dBA.
75 Noise levels greater than 85 dBA can cause temporary or permanent hearing loss. Examples of low daytime levels are isolated, natural settings with noise levels as low as 20 dBA and quiet suburban residential streets with noise levels around 40 dBA.

Noise levels above 45 dBA at night can disrupt sleep. Examples of moderate level noise environments are urban residential or semi-commercial areas (typically 55–60 dBA) and commercial locations (typically 60 dBA). People may consider louder environments adverse, but most will accept the higher levels associated with noisier urban residential or residential -commercial areas (60-75 dBA) or dense urban or industrial areas (65–80 dBA).

It is widely accepted that in the community noise environment, the average healthy ear can barely perceive CNEL noise level changes of 3 dBA. CNEL changes from 3 to 5 dBA may be noticed by some individuals who are extremely sensitive to changes in noise. A 5 dBA CNEL increase is readily noticeable, while the human ear perceives a 10 dBA CNEL increase as a doubling of sound.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 82 Noise levels from a particular source generally decline as distance to the receptor increases. Other factors, such as the weather and reflecting or barriers, also help intensify or reduce the noise level at any given location. A commonly used rule of thumb for roadway noise is that for every doubling of distance from the source, the noise level is reduced by about 3 dBA at acoustically “hard” locations (i.e., the area between the noise source and the receptor is nearly complete asphalt, concrete, hard-packed soil, or other solid materials) and 4.5 dBA at acoustically “soft” locations (i.e., the area between the source and receptor is normal earth or has vegetation, including grass). Noise from stationary or point sources is reduced by about 6 to 7.5 dBA for every doubling of distance at acoustically hard and soft locations, respectively. Noise levels are also generally reduced by 1 dBA for each 1,000 feet of distance due to air absorption. Noise levels may also be reduced by intervening structures – generally, a single row of buildings between the receptor and the noise source reduces the noise level by about 5 dBA, while a solid wall or berm reduces noise levels by 5 to 10 dBA. The normal noise attenuation within residential structures with open windows is about 17 dBA, while the noise attenuation with closed windows is about 25 dBA.

Construction activities would generate temporary noise from equipment use; the most common noise generated would be from mobile diesel equipment such as excavators, pick -up trucks, saws, a 10-wheel dump truck, and a telehandler. Activities would be restricted to the hours of 7:00 A.M. to 5:00 P.M., Monday through Friday per the City’s Municipal Code.

Table 3 illustrates typical noise levels from construction equipment at a reference distance of 50 feet.

Noise levels from construction equipment attenuate at a rate of six (6) dBA per doubling of distance.

Therefore, the noise levels at a distance of 100 feet would be six (6) dBA less than those shown in Table 3. Construction equipment would generate maximum noise levels of approximately 101 dB at 50 feet.

Construction noise levels may periodically exceed noise standards in the existing Noise Ordinance, but the temporary noise from construction would not cause a substantial increase in ambient noise or expose sensitive receptors to unacceptable noise levels for long periods of time.

Noise-Sensitive Receptors
Noise‐sensitive land uses are generally considered to include those uses where noise exposure could result in health‐ related risks to individuals, as well as places where quiet is an essential element of their intended purpose. Residential dwellings are of primary concern because of the potential for increased and prolonged exposure of individuals to both interior and exterior noise levels. Additional land uses such as parks, historic sites, cemeteries, and recreation areas are also considered sensitive to increases in exterior noise levels. Schools, churches, hotels, libraries, and other places where low interior noise levels are essential are also considered noise‐sensitive land uses. The nearest sensitive receptors consist predominantly of residential dwellings on the southeastern side of East Poplar Avenue and the southwestern side of US -101, approximately 290 and 380 feet away from Site 1, respectively.

• No individual piece of equipment shall produce a noise level exceeding 90 dBA at a distance of 25 feet. If the device is housed within a structure or trailer on the property, the measurement shall be made outside the structure at a distance as close to 25 feet from the equipment as possible.
• The noise level at any point outside of the property plane of the project shall not exceed 90 dBA.

City of San Mateo 2030 General Plan
The City of San Mateo 2030 General Plan contains a noise-sensitive land use and noise compatibility matrix which summarizes the normally acceptable, conditionally acceptable, and normally unacceptable noise levels for various land uses. The matrix describes that for parks and playgrounds, typically noise levels greater than 65 dBA CNEL are unacceptable. 79 The project site
is within a golf course that is zoned as parks/open space and is a noise-sensitive land use category.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 85 The following noise-related policies provided in the City of San Mateo 2030 General Plan are relevant to this proposed project:
• Policy N-2.1: Continue implementation and enforcement of the City's existing noise control ordinance: a) which prohibits noise that is annoying or injurious to neighbors of normal sensitivity, making such activity a public nuisanc e, and b) restricts the hours of construction to minimize noise impact.
• Policy N-2.2: Protect all “noise-sensitive” land uses listed in Tables N-1 and N-2 from adverse impacts caused by the noise generated on-site by new developments. Incorporate necessary mitigation measures into development design to minimize noise impacts. Prohibit long-term exposure increases of 3 dB (Ldn) or greater at the common property line, or new uses which generate noise levels of 60 dB (Ldn) or greater at the property line, excluding existing ambient noise levels.

Discussion of Impacts
a) Less than Significant Impact with Mitigation Incorporated. Construction activities would generate temporary noise from equipment use. T he most common noise generated would be from mobile diesel equipment such as excavators, pick-up trucks, saws, a 10-wheel dump truck, and a telehandler. Activities would be restric ted to the hours stipulated by the City’s municipal code.

Table 3 illustrates typical noise levels from construction equipment at a reference distance of 50 feet. Noise levels from construction equipment attenuate at a rate of six (6) dBA per doubling of dis tance. Therefore, the noise levels at a distance of 100 feet would be six (6) dBA less than those shown in Table 3. Construction equipment would generate maximum noise levels of approximately 88 dB at 50 feet.

Construction noise levels may periodically exceed noise standards in the existing M unicipal Code, but the temporary noise from construction would not cause a substantial increase in ambient noise or expose sensitive receptors to unacceptable noise levels for long periods of time. Impacts associated with construction noise would cause a potentially significant, temporary increase in noise levels, but i ncorporation of Mitigation Measure NOI -1 would reduce noise impacts to a less than significant level.

Long-term operational noise impacts would be less than significant because the conditions would be similar to existing noise levels.

Impact NOI-1: Construction noise could exceed the City of San Mateo Municipal Code standard.

Mitigation Measure NOI– 1: The City shall incorporate the following practices into the construction documents to be implemented by the project contractor:
• Construction hours shall be limited to 7:00 A.M. to 5:00 P.M., Monday through Friday only.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 86 • Notify businesses, residences, and noise-sensitive land uses adjacent to construction sites of the construction schedule in writing. Designate the City’s construction manager as respons ible for responding to any local complaints about construction noise. The construction manager shall determine the cause of the noise complaints (for example starting too early, or a bad muffler) and institute reasonable measures to correct the problem. Conspicuously post a telephone number for the construction manager at the construction site. • Maximize the physical separation between noise generators and noise receptors. Such separation includes, but is not limited to, the following measures:
 Use heavy-duty mufflers for stationary equipment and barriers around particularly noisy areas of the site or around the entire site;  Where feasible, use shields, impervious fences, or other physical sound barriers to inhibit transmission of noise to sensitive receptors;  Locate stationary equipment to minimize noise impacts on the community; and
 Minimize backing movements of equipment.
• Use quiet construction equipment whenever possible.
• Impact equipment (e.g., jack hammers and pavement breakers) shall be hydraulically or electrically powered wherever possible to avoid noise associated with compressed air exhaust from pneumatically -powered tools.

Compressed air exhaust silencers shall be used on other equipment. Other quieter procedures, such as drilling rather than using impact equipment, shall be used whenever feasible.
• Prohibit unnecessary idling of internal combustion engines. b) Less than Significant Impact. Ground-borne vibration and noise is typically associated with blasting operations, the use of pi le drivers, and large -scale demolition activities. The proposed project would not require the use of any of these activities. Saw cutting into the concrete-lined creek bed would be required to install the trash capture device, but these activities would not generate ground-borne vibration. The impact would be less than significant.
c) No Impact. The project site falls under the Comprehensive Airport Land Use Compatibility Plan for the Environs of San Francisco International Airport. San Francisco Internati onal Airport is located approximately 2.7 miles northeast of the project site. However, the airport land use plan noise contour map asserts that the noise from aircraft activity associated with DocuSign Envelope ID: C473E141-36D3-4044-A1EC-D26583CE2809 145 of 662

Discussion of Impacts
a, b) No Impact. The project would install a trash capture device in Poplar Creek at Site 1 and enhance vegetation along the banks of the creek at Stream Enhancement Site 2. The trash capture device would remove pollution from the stormwater system before it reaches the San Francisco Bay. The project would be constructed in the creek and the associated City owned golf course property and would not displace people or housing. The project would not result in the construction of new housing and therefore would not result in a substantial increase in population or housing units in the City. No impacts would occur.

Public Schools
Three (3) school districts serve the City of San Mateo: the San Mateo- Foster City School District (SMFCSD) serves grades K–8; the San Mateo Union High School District serves grades 9–12; and the County Community College District serves high school graduates and anyone over 18. 84 SMFCSD operates 20 schools. San Mateo Union High School District operates seven (7) high schools, and one (1) adult school. The County Community College District operates three (3) community colleges throughout San Mateo County.

Parks and Recreational Facilities
The City of San Mateo has more than 12 neighborhood parks, nine (9) larger community parks, six (6) recreation/community centers, two (2) pools, two (2) community gardens, a shoreline regional park system, small “mini” parks, an estuary lagoon for boating, and the Poplar Creek 18-hole golf course totaling approximately 200 acres of open space within City l imits.85 There are more than 40 miles of paths and trails throughout the City.

Discussion of Impacts
a) No Impact. Given the proposed project would not increase the existing residential or employment population in the City, the project would not result in a long-term increase in the demand for public services, schools, public facilities or require construction of new governmental facilities, such as libraries . There would be no road closures associated with the project, so response times for fire and police protection services would not be impacted.

Therefore, no impacts to fire protection, police protection, schools, and other public facilities would occur.

Less than Significant Impact. The purpose of the project is to install a trash capture device in Poplar Creek and enhance native vegetation along the creek’s extent. The proposed project would occur in the Poplar Creek Golf Course, which is a City owned and operated park. However, golf course function would not be disturbed during construction or operation.

The stream enhancement area would be located outside of high traffic areas for golfers and therefore would not impact recreational opportunities for golfers. Impacts to parks would therefore be less than significant.

Environmental Setting
The project site is located in Poplar Creek which runs through the Poplar Creek Golf Course. This golf course is owned and operated by the City of San Mateo Parks and Recreation Department. The course is a standard 18 -hole golf course that was built in 1933 and was completely remodeled in 1999.86
Discussion of Impacts
a, b) Less than Significant Impact. Given the proposed project would not increase the existing residential or employment population in the City , the project would not increase the use of nearby recreational facilities. The purpose of the project is to install a trash capture device within Poplar Creek and enhance vegetation along the creek. Although the project occurs within the footprint of a City park, golfing activities would not be interrupted during construction or operation. The trash capture device would be installed in an area away from the active golf course and would not be accessible to golfers. The stream enhancement area location is approximately 290 feet from the closest putting green. There would be a less than significant impact on recreational facilities.

Environmental Setting
The project site is located within and adjacent to Poplar Creek, immediately north of the intersection of East Poplar Avenue and North Bayshore Boulevard. North Bayshore Boulevard runs parallel to US-101, a major highway that runs the length of the west coast. No streets, sidewalks, pedestr ian trails, or bicycle paths run through the project site or its vicinity.

Regulatory Setting
The San Mateo 2030 General Plan Circulation Element focuses on human mobility such as public transit, bikeways, pedestrian routes, roadways, and parking facilities. The plan lists North Bayshore Boulevard as a Collector street. A c ollector street links neighborhoods to arterials and are not intended for through traffic but are nonetheless intended to move traffic in an efficient manner. 87 San Mateo County Transportation Authority Strategic Plan 2020-2024 The San Mateo County Transportation Authority was established in 1988 through the approval of Measure A, a 20-year half-cent sales tax to fund and leverage other funding sources for transportation projects and programs in San Mateo County.

• Implement environmentally -friendly transportation solutions and projects that incorporate green stormwater infrastructure and plan for climate change • Facilitate the reduction of vehicle miles traveled, travel times, and greenhouse gas emissions Discussion of Impacts
a) No Impact. The proposed project would not impact traffic on local roads or highways during construction or operation. The project would always maintain all lanes of traffic on surrounding roadways . Construction equipment would be staged in an existing ruderal grassland area adjacent to Poplar Creek. The area would be graded to allow for continued access to the trash capture device. There would be no impact to traffic on local roads or highways.
b) Less than Significant Impact. A significant impact may occur if the proposed project were to be inconsistent with provisions outlined in CEQA Guidelines section 15064.3, subdivision (b), which sets forth criteria for analyzing transportation impacts. Under the CEQA Guidelines, a lead agency has discretion to choose the most appropriate methodology to evaluate a project’s vehicle miles traveled, including a qualitative analysis.

Construction traffic (equipment and materials transport and daily worker traffic) would marginally increase traffic on local roads during the temporary construction phase of the proposed project. Temporary construction traffic would be limited to equipment delivery and material transport, and a few employee vehicles daily, which would be parked on-site at the gravel turnaround and out of the way of main streets. The temporary construction-related traffic would not result in a noticeable increase in traffic on local roads.

The impact of maintenance vehicles during the operational phase would not significantly alter existing traffic conditions. One (1) maintenance vehicle would access the site. The impact of construction and maintenance vehicles would be less than significant. c) No Impact. The proposed project would install a trash capture device within Poplar Creek and would enhance vegetation around the creek’s banks. No work is proposed to roadways or pathways. The project would be constructed in accordance with City design standards that will ensure that hazards due to a design feature would be avoided. Therefore, impacts would be less than significant.
d) No Impact. The proposed project is located within Poplar Creek Golf Course.

significance of the resource to a California Native
American tribe.

Environmental Setting
Tribal cultural resources are defined in CEQA Guidelines Section 21074 as sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe that are also either: (a) included or determined to be eligible for inclusion in the CRHR, or (b) included in a local register of historical resources, as defined in Public Resources Code section 5020.1(k). A tribal cultural resource would be significantly affected if a project has the potential to substantially alter in an adverse manner the significant characteristics of the resource. Such an impact would result if such a resource were disturbed during construction.

On October 21, 2021, the City of San Mateo sent out notification letters to Native American tribes pursuant to AB 52. On October 24, 2021, the Kanyon Sayers-Roods, a tribal representative on behalf of the Indian Canyon Band of Costanoan Ohlone People, responded to the request. Table 4 below shows the contact log documenting the City’s attempts to reach out to the tribal representative to inquire further about this request.

Regulatory Setting
Assembly Bill 52
In September 2014, the California Legislature passed AB 52, which added provisions to the Public Resources Code (PRC) concerning the evaluation of impacts on tribal cultural resources under CEQA, and consultation requirements with California Native American tribes. In particular, AB 52 now requires lead agencies to analyze a project’s impacts on “tribal cultural resources,” separately from archaeological resources (PRC Section 21074; 21083.09). Under AB 52, “tribal cultural resources” include “sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe” that are either (1) listed, or determined to be eligible for listing, on the state or local register of historic resources; or (2) a resource that the lead agency chooses, in its discretion, to treat as a tribal cultural resource (PRC Section 21074).

AB 52 also requires lead agencies to engage in additional consultation procedures with respect to California Native American tribes (PRC Sections 21080.3.1, 21080.3.2, 21082.3). If a project may have a significant impact on a tribal cultural resource, the lead agency’s environmental document must discuss (1) whether the proposed project has a significant impact on an identified tribal cultural resource and (2) whether feasible alternatives or mitigation measures avoid or substantially less the impact on the identified tribal cultural resource (PRC Section 21082.3(b)). Finally, AB 52 required the Office of Planning and Research to update Appendix G of the CEQA Guidelines by July 1, 2016, to provide sample questions regarding impacts to tribal cultural resources (PRC Section 21083.09).

AB 52’s provisions apply to projects that have a notice of preparation filed on or after July 1, 2015.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 96 Discussion of Impacts
a-i, ii) Less than Significant Impact with Mitigation Incorporated.

As described above, the City did not receive a response from the Indian Canyon Band of Costanoan Ohlone People tribe and therefore concluded AB 52 consultation.

The project is located within a concrete-lined channel and is on reclaimed and artificially filled land. As such, there is a low sensitivity for tribal cultural resources to be encountered during construction. All project work would occur within existing distur bed areas and no improvements would require additional large-scale excavation.

Any prehistoric archaeological resources or human remains that may be encountered during construction could represent tribal cultural resources. In the unlikely event that archaeological resources or human remains are encountered during project activities, Mitigation Measure CULT-1 and CULT-2 would be implemented to ensure the discovery is preserved. Per Public Resources Code 5097.98 and Health and Human Safety Code 7050.5, if human remains are encountered, excavation or disturbance of the location shall be halted in the vicinity of the find, and the County Coroner contacted. If the Coroner determines the remains are Native American, the Coroner shall contact the Native American Heritage Commission, who shall identify the person or persons believed to be most likely descended from the deceased Native American in order to provide guidance on handling the remains.

Implementation of Mitigation Measure CULT-1 and CULT-2 in Section V , along with compliance with State law, would ensure that impacts to tribal cultural resources would be less than significant.

The majority of the City of San Mateo, including the section where the project site is located, receives its water from the California Water Service Company (Cal Water) as part of the Mid-Peninsula District89. The Mid-Peninsula District serves San Mateo as well as San Carlos and parts of unincorporated Redwood City, The Highlands, and Palomar Park. The service area is approximately 17 square miles and includes 137,217 residents. The average daily demand of the district is

12.90 million gallons per day. The distribution system includes 22 pressure zones in San Carlos, 18 in San Mateo, 62 booster pumps, 38 storage tanks, 2,832 hydrants, and 363 miles of main. 90 Solid Waste
The average San Mateo resident produces 3.9 pounds of garbage a day and the average City employee produces 7.6 of garbage per day. This is less than the California average of 5.8 pounds per resident and 13.3 pounds per employee.
91 Recology provides solid waste and recycling collection services for the City of San Mateo. Upon collection, refuse is taken for sorting at the San Carlos Transfer Station. Non-recyclable waste is disposed of at the Ox Mountain Landfill in Half Moon Bay. The Ox Mountain landfill is permitted by the California Integrated Waste Management Board to receive 3,598 tons per day or 1.3 million tons per year. The landfill’s maximum capacity is 60.5 million cubic yards, with an estimated closure year of 2034.

As such, there would be less-than-significant impacts related to water supply and wastewater treatment capacity.
d, e) Less than Significant Impact. The project would generate soil spoils and solid waste from grading of the staging area and saw cutting of the existing concrete- lined channel during construction. In total, approximately 30 CY of fill would be removed and disposed of during construction. During operation, solid waste would be generated from the removal of accumulated debris from the trash capture device. The trash capture device has the ability to capture 8.8 cubic feet of litter when the screen is 50 percent full. Monthly visual inspections during the wet season would ensure that the device would be cleaned once the 50 percent capacity threshold has been reached. This is anticipated to occur two (2) to three (3) times per year. At this rate, the maximum amount of trash that would be removed and transported to the Ox Mountain landfill per year would be approximately 26.4 cubic feet. The Ox Mountain Landfill has capacity to support the projected amount of trash collected by proposed trash rack device. Any materials used during construction would be properly disposed of in accordance with federal, state, and local regulations. Impacts related to solid waste facilities, statutes, and regulations would be less than significant.

c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment?

d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a
result of runoff, post -fire slope instability, or drainage changes?

Environmental Setting
CAL FIRE maps identify fire hazard severity zones in the State and local responsibility areas. There are no wildland fire hazard areas within the City of San Mateo. 93 The proposed project site is within a concrete-lined channel and a maintained golf course with very little slope.

Discussion of Impacts
a-d) No Impact. The project site is flat, outside the Wildland Urban Interface, and is not considered a High Severity Zone for wildfire. There would be no impact.

No
Impact
a) Does the project have the potential to substantially degrade the quality of the environment,
substantially reduce the habitat of a fish or wildlife
species, cause a fish or wildlife population to drop
below self-sustaining levels, threaten to eliminate a
plant or animal community, substantially reduce the
number or restrict the range of a rare or
endangered plant or animal or eliminate important
examples of the major periods of California history
or prehistory?

b) Does the project have impacts that are individually
limited, but cumulatively considerable?
(“Cumulatively considerable” means that the
incremental effects of a project are considerable
when viewed in connection with the effects of past
projects, the effec ts of other current project s, and
the effects of probable future projects)?

c) Does the project have environmental effects that
will cause substantial adverse effects on human
beings, either directly or indirectly?

Discussion of Impacts
a) Less than Significant Impact with Mitigation Incorporated. As discussed in prior sections of this IS/MND, the project would not degrade the quality of the environment, substantially affect biological resources, or eliminate important examples of California history or prehistory with implementation of the identified mitigation measures. As discussed in Section III, Air Quality, implementation of Mitigation Measure AIR -1 would reduce potentially significant air quality impacts to a less -than-significant level. As discussed in Section IV, Biological Resources, implementation of Mitigation Measure BIO -1 would reduce impacts to nesting birds to a less -than-significant level. As discussed in Section V, Cultural Resources, implementation of Mitigation Measures CULT-1 and CULT-2 would reduce impacts to historic resources, archaeological resources, and human remains to a less-than-significant level. As discussed in Section XIII, Noise, temporary noise impacts generated during construction of the project would be reduced to a less-than-significant level with implementation of Mitigation Measure NOI-1. Therefore, significant project -level impacts can all be mitigated to a less-than-significant level with mitigation incorporated.

Poplar at Golf Course Trash Capture Project Final Initial Study/Mitigated Negative Declaration City of San Mateo January March 2022 102
b) Less Than Significant Impact with Mitigation Incorporated. Cumulatively considerable means that the incremental effects of an individual project are considerable when viewed in connection with the effects of past projects, the effects of other current proj ects, and the effects of probable future project s. The analysis within this IS/MND demonstrates that the project would not have any individually limited, but cumulatively considerable impacts. As presented in the analysis in Section III, Air Quality, Secti on IV, Biological Resources, Section V, Cultural Resources, Section XIII, Noise, and Section XVIII, Tribal Cultural Resources, any potentially significant impacts would be less than significant after mitigation.

Due to the limited scope of direct physical impacts to the environment associated with construction, the project’s impacts are project-specific in nature. Compliance with the conditions of approval issued for the proposed development would further assure that project-level impacts would not be cumulatively considerable. Consequently, the project along with other cumulative projects would create a less than significant cumulative impact with respect to all environmental issues.
c) Less Than Significant Impact with Mitigation Incorporated. Consistent with Section 15065(a)(4) of the CEQA Guidelines, a lead agency shall find that a project may have a significant effect on the environment where there is substantial evidence that the project has the potential to cause substantial adverse effects on human beings, either directly or indirectly. Under this standard, a change to the physical environment that might otherwise be minor must be treated as significant if people would be significantly affected. This factor relates to adverse changes to the environment of human beings generally, and not to effects on particular individuals. While changes to the environment that could indirectly affect human beings would be represented by all the designated CEQA issue areas, those that could directly affect human beings include construction air quality, hazardous materials, and noise.

The proposed project would adhere to General Plan policies and implement mitigation measures to reduce potential impacts to a less than significant level. Section III, Air Quality, implementation of Mitigation Measure AIR -1 would reduce potentially significant air quality impacts to a less-than-significant level. As discussed in Section XIII, Noise, temporary noise impacts generated during constructi on of the project would be reduced to a less-than-significant level with implementation of Mitigation Measure NOI-1. No other direct or indirect adverse effects on human beings have been identified. Impacts on human beings would be less than significant with implementation of mitigation measures.

Project Description
The proposed project will consist of installing netting or screening device(s) within the existing City storm drain channel located on the southwest corner of Poplar Creek Golf Course. The channel is trapezoidal and concrete. A weir will be installed across the channel to attach the trash device(s) and allow for the bypass of flows greater than the treatment event over the weir. The channel drains portions of the City of San Mateo and Caltrans ROW, specifically Highway 101 and El Camino Real, and discharges to the forebay of the City’s Poplar Pump Station. Both the Roscoe Moss Storm Flo and the OldCastle Net-Tech devices are being considered and are covered by this analysis, however the (2) 40’ Roscoe Moss 30” diameter screens are depicted in Figure 1.

For the purposes of this preliminary study a weir height of three feet was assumed to support the trash device(s) and assumes the trash devices are full. An existing MIKE URBAN hydraulic model of the City storm drain network was utilized to compare the impacts of weir placement in the channel at locations #1 and #2 to the existing condition. The model, developed by Schaaf & Wheeler on behalf of the City for the design of the Poplar pump station, uses a 100-year 72-hour design storm. This storm event was used to compare impacts of the device location.

Hydraulic Impacts
Location #2 (green), due to its proximity to the culverts under North Bayshore and Highway 101, results in approximately three feet of head loss at the project location. This increases the hydraulic grade upstream of the project site location of two to three feet which extends throughout the City system west of Highway 101. The Location #2 hydraulic grade line is depicted in Figure 2 below in green. By placing a blockage in the reach upstream of the maintenance yard access bridge, the head loss due to the culverts under Highway 101 is exacerbated.

Location #1 (red) is further from the freeway culverts and within the backwater associated with the Poplar pump station forebay, downstream of the access road bridge. Due to both the backwater effects and the distancing from the culverts, there is significantly lower head loss generated by the device, on the order of approximately one foot total. The loss dissipates upstream as shown by the red hydraulic grade line in the system profile in Figure 2 which is nearer to the existing condition in dark blue.

The furthest upstream location the device can be placed without significant hydraulic impact to the storm drain system is just downstream of the maintenance yard access bridge.
