Mr. Jeff Kraft RE: GEOTECHNICAL REVIEW
105 Scenic Drive GRADING AND DRAINAGE PLANS
Redwood City, California 94062 KRAFT RESIDENCE

MONTE CRESTA DRIVE

BELMONT, CALIFORNIA
Dear Mr. Kraft:

As requested, we have reviewed the design review grading and drainage plans for your proposed residence and adjacent fire truck turn-around at the western terminus of Monte Cresta Drive in Belmont. As you know, we performed a geologic and geotechnical investigation for your residence and the adjacent fire truck turn-around and presented the results in a geotechnical report dated January 29, 2016.

We reviewed the geotechnical elements of design review civil plan sheets C0.1, C2.0, C3.0, C4.0, and C6.3, dated May 15, 2018, prepared by BKF Engineers.

Based on our review, it is our opinion that the civil plan sheets referenced above have been prepared in essential compliance with our geotechnical recommendations for the project, with the following items noted.

1. The amount of storm water runoff that has historically flowed across the property will not be increased significantly by the proposed construction. Due to the presence of bedrock at a shallow depth, construction of the proposed storm water disposal system is not expected to cause deep-seated landsliding or significant erosion on the property provided the storm water detention and disposal system is constructed as shown on the plans referenced above modified as indicated in this plan review letter.

2. In our opinion, it is unreasonable and unnecessary to require the contractor to report to the project manager any differences greater than 0.05 feet (0.6 inches) between the elevations shown on the civil plans and actual elevations in the field at the start of construction, as specified on General Site Note 3 on sheet C0.1.

3. The date of our geotechnical report for the project is January 29, 2016 (rather than December 2015, as indicated on General Site Note 6 on sheet C0.1).

4. To avoid misunderstanding, the 8- to 10-foot high retaining wall below the sidewalk and the northern end of the driveway bridge should be shown (at least conceptually) on the civil plans and on Section AA on sheet C3.0.

5. To avoid misunderstanding, the plans should include a construction detail and/or notes for the fire truck turn-around pavement section that is to be “approved” by the geotechnical engineer, as indicated on the note on sheet C2.0. 1390 El Camino Real, Second Floor | San Carlos, CA 94070 | (650) 591-5224 | www.romigengineers.com 457
Mr. Jeff Kraft Geotechnical Review of Design Review Civil Plans Page 2 of 3

6. The retaining wall backdrains and their discharge locations should be shown on sheet C4.0.

7. The storm water detention and metered release through a 4-inch storm drain pipe at the northeastern corner of the property referred to on the catch basin notes on sheet C4.0 do not appear to be included on standard details 1, 2, 3, and 4 on sheet C6.2.

8. We note that the “detention system” is shown on detail 7/C6.3 (rather than on detail 5/C6.3, as indicated on sheet C4.0).

9. We note that the level spreaders are to be 24-feet wide, as indicated on detail 1/C6.3 (rather than 20-feet long, as indicated on sheet C4.0).

10. The stitch piers shown on sheet C4.0 should extend beyond the ends of the 24-foot long level spreader. If stitch piers are required, their location, diameter, depth, and spacing will depend on the soil condition and depth to bedrock at the stitch piers (rather than installed 3-feet on-center, as indicated on the note on sheet C4.0).

11. To avoid misunderstanding, the locations where the “sedimentation inlet” shown on detail 4/C6.3 are to be installed should be shown on sheet C4.0.

12. The “staked level-header” board and erosion control blanket should be shown and specified on detail 1/C6.3.

13. In our opinion, the minimum depth of the bench cut and rock rip-rap for the level spreaders should be at least 2 feet (rather than 1 foot, as indicated on detail 1/C6.3).

14. To avoid misunderstanding, the minimum width of the excavation for the detention system beyond the side of the detention pipe should be specified on detail 7/C6.3.

We make no warranty, expressed or implied, for the services we perform for this project.

Our services are performed in accordance with the geotechnical engineering principles generally accepted at this time and location.

MONTE CRESTA DRIVE

BELMONT, CALIFORNIA
Dear Mr. Kraft:

As requested, we have reviewed the updated grading and drainage plans for your proposed residence and adjacent cul-de-sac/fire truck turn-around at the western terminus of Monte Cresta Drive in Belmont. As you know, we performed a geologic and geotechnical investigation for your residence and the adjacent fire truck turn-around and presented the results in a geotechnical report dated January 29, 2016.

We reviewed the geotechnical elements of civil plan sheets C0.1, C2.0, C3.0, C4.0, C4.1, and C6.2, dated October 10, 2019, prepared by BKF Engineers.

The civil plans referenced above are intended to direct storm water runoff from the Monte Cresta Drive right-of-way and the proposed cul-de-sac down the alignment of Monte Cresta Drive (rather than to a detention system that discharges onto a level-spreader in the southern portion of the Kraft property). The portion of the storm water runoff from the driveway and residence that exceeds the pre-development runoff will be discharged onto Monte Cresta Drive. This will reduce the amount of storm water runoff that has historically flowed onto and across the Kraft property and onto the adjacent property to the south. The proposed grading and drainage plans will reduce the potential for erosion and slumping of surface soil on and below the Kraft property.

Based on our review, it is our opinion that the civil plans referenced above are consistent with site conditions, the recommendations in our geotechnical report, and supplemental information that has been reviewed and discussed with the project team.

We make no warranty, expressed or implied, for the services we perform for this project.

Our services are performed in accordance with the geotechnical engineering principles generally accepted at this time and location.

Please call if you have questions or comments about site conditions or the results of our geotechnical review of the civil plans for your residence and the adjacent cul-de-sac.

Petaluma, California 94952 ADJACENT TO KRAFT PROPERTY
LOT 55 MONTE CRESTA DRIVE

BELMONT, CALIFORNIA
Dear Mr. Kraft:

This letter was prepared in response to an email to you, dated October 17, 2023, from Mr.

Rob Gill, a Senior Planner for the City of Belmont, regarding the proposed fire-truck turnaround at the present southern terminus of Monte Cresta Drive in front of your property (APN 043-165-180) in Belmont, California. Mr. Gill also asked us to clarify whether extension of Monte Cresta Drive further to the north was feasible and practical.

Romig Engineers’ Geologic and Geotechnical Feasibility Study Report, dated June 30, 2008, addressed the feasibility of constructing an 1,800-foot-long Through Road Connection of Monte Cresta Drive. This study and report was prepared for Mr. Damon Campbell who originally planned to extend Monte Cresta Drive 104 feet for access to his proposed residence. Our Feasibility Study concluded that the originally proposed 104- foot long road extension was feasible without encountering any significant geologic or geotechnical constraints.

Romig Engineers concluded that constructing a continuous Through Road Connection of Monte Cresta Drive is not practical or feasible due to existing geologic conditions and constraints in the central portion of the road right-of-way alignment, primarily the presence of two, Ms landslides and one large Pd landslide.

Romig Engineers concluded that it would be technically possible, although very difficult and expensive, even if allowed by the City, to extend Monte Cresta Drive approximately 750 feet to the north to the existing spur ridge near Station 17+50 (see Figures 4 and 5 of 2008 Feasibility report). This extension would require stabilizing at least portions of seven small landslides (Qls’A’) mapped within the roadway alignment. The comment in paragraph 4 on page 19 of our 2008 Feasibility Report indicating that construction of this section of roadway was not currently considered feasible or reasonable was intended to mean not feasible due to City requirements, negative public pressure, fractionated property ownership, and practical funding issues (rather than not feasible from the geotechnical engineering point-of-view). The City’s geologic and geotechnical consultant confirmed their agreement of our conclusions in a letter to the City, dated August 13, 2008.

Due to difficult geologic conditions between the originally addressed 104 foot road extension and the spur ridge, detailed site investigations would need to be performed for design and construction of the road extension and for any and all individual lots proposed for development in the future. Some of the lots along the potential future road extension are expected to be negatively influenced by potentially unstable slope conditions. 1390 El Camino Real, Second Floor | San Carlos, CA 94070 | (650) 591-5224 | www.romigengineers.com 464
Mr. Jeff Kraft Monte Cresta Drive Extension Page 2 of 2 Belmont Code Section 7-13 requires a turnaround at the end of dead-end roads that are 800 feet or longer, which is the case for the subject section of Monte Cresta Drive. Any further extension of the roadway beyond the turnaround would be at the discretion of the City Engineer and Fire Marshal. Given conditions and constraints beyond 104 feet from the current road terminus, the currently proposed location for the fire truck turnaround is practical and preferred. Construction of the proposed fire truck turnaround will not prevent the possible future extension of Monte Cresta Drive to Station 17+50 if that is desired and funded by the property owners along this portion of the right-of-way, approved by the Fire Marshal and the City Engineer, and is shown to be safe, feasible, and affordable.

The proposed fire truck turnaround in front of the Kraft property was addressed in our geotechnical report, dated January 29, 2016, and in our Geologic and Geotechnical Report Update, dated February 23, 2017. The City’s geologic and geotechnical consultant confirmed their agreement with our conclusions and recommendations for the proposed fire truck turnaround and the Kraft property in a letter to the City, dated October 26, 2017.

The information presented in our February 23, 2017 Geologic and Geotechnical Update letter for the fire truck turnaround and the Kraft property is consistent with the findings and conclusions presented in our June 30, 2008 Geologic and Geotechnical Feasibility Study for the Monte Cresta Drive Road Extension, as clarified in this letter.

We make no warranty, expressed or implied, for the services we perform for this project.

Our services are performed in accordance with the geotechnical engineering principles generally accepted at this time and location.

Geotechnical Peer Review
RE: Kraft Residence
Lot 55 Monte Cresta Drive
(APN 043-165-180)
December 10, 2015
B5105
At your request, we have completed a geotechnical peer review of the proposed single-family residence site development concept using:
•
•
•
Feasibility Evaluation, Single Family Residence (letter-report) prepared by Romig Engineers, Inc., dated December 3, 2015; Architectural Plans (16 Sheets) prepared by Chris Pardo Design, dated September 4, 2015; and
Civil Design Plans (3 Sheets) prepared by Triad/Holmes
Associates, dated November 10, 2015.

In addition, we have completed a recent inspection of site conditions and reviewed pertinent technical maps and reports from our office files (B4030 and B5113).

DISCUSSION
The applicant proposes to construct a three-story residence with a driveway bridge extending from the terminus of Monte Cresta Drive. Construction of a 62-foot diameter tum-around is proposed at the western terminus of Monta Cresta Drive requiring fill placement (estimated at 154 cubic yards) and consb:uction of a retaining wall to 3.6 feet in height along the southern side of the tum-around. Proposed cuts for the new residence totals 154 cubic yards, and this material is to be used for turn-around construction. Current plans do not clearly depict where surface drainage from the new turn-around (and future Campbell driveway to the north) will be discharged. We understand that a 20-foot long infiltration trench is proposed immediately downslope of the new residence that will accommodate roof drainage. H ·appears that turn-around construction must be coordinated with driveway construction to the Campbell residence Northern California Office

or additional temporary retaining walls may be required along the northern side of the turn-around.

SITE CONDITIONS
The vicinity of the proposed residence is generally characterized by a steep (approximate 40 percent inclination) south-facing slope. A very steep to precipitous cut slope of approximately 25 feet in height is located along the southwestern perimeter of the property. This cut exposes relatively competent Franciscan bedrock. Fill materials are present beneath the proposed house site, possibly on the order of 5 feet in thickness or less. Drainage is characterized by sheetflow to the south.

The property is generally underlain by shallow sandstone bedrock of the Franciscan Complex. The bedrock appears to be generally overlain by shallow sandy clay ( colluvium) and several feet of undocumented fill materials. The majority of the proposed residence is located within the "Ps" designation indicating the potential for creep or shallow landsliding. The southeastern portion of the property is mapped as "Pfs" indicating the presence of fill materials that maybe susceptible to instability.

CONCLUSIONS AND RECOMMENDED ACTION
Proposed site development is somewhat constrained by steep slopes, existing fill materials of undetermined depth, and very strong seismic ground shaking. The Project Geotechnical Consultant has completed a feasibility level evaluation of proposed site development based on surface inspection, photograph and document review without completion of subsurface investigation to define depths of competent supporting materials. The Consultant concludes that the site is suitable for proposed residential development but recommends that geotechnical aspects of project design be based on the detailed design-level geotechnical report that is currently in progress.

We agree that single-family residence construction is likely feasible at the subject property if appropriate pier foundation design parameters are developed and measures to achiev� stable discharg� of site drainage are clarified. We note that Romig Engineers initially concluded that construction of a row of stitch piers located downslope of the drainage spreader would be advisable. Such stitch piers are not depicted on the submitted plans. Also, it is unclear how drainage from the new Monte Cresta Drive turn-around will be conveyed and discharged. We recommend that the following Items 1 and 2 be satisfactorily addressed prior to geotechnical approval of specific site development plans:

1. Street and Site Draina�e - The proposed conveyance and discharge of storm water collected at the proposed Monte Cresta Drive tum-around should be clarified. The Project Geotechnical Consultant should evaluate the proposed position and design of site residential drainage discharge with respect to potential COTTON, SHIRES AND ASSOCIATES, INC. 467

erosion or slope stability impacts. Multiple drainage discharge locations should be considered. Use of stitch piers below the primary discharge should be considered. Any proposed discharge of street drainage across the subject property should be evaluated from a geotechnical perspective.

Geotechnical Investigation - A design-level geotechnical investigation for the project should be completed including subsurface investigation. We understand this investigation will also include providing recommended geotechnical grading criteria for the proposed street tum-around and design
parameters for associated retaining walls.

Appropriate documentation and revised plans to address the above two items should be submitted to the City Engineer and City Geotechnical Consultant after formal approval by the Project Geotechnical Consultant.

LIMITATIONS
This geotechnical peer review has been performed to provide technical advice to assist the City with its discretionary permit decisions. Our services have been limited to review of the documents previously identified, and a visual review of the property. Our opinions and conclusions are made in accordance with generally accepted principles and practices of the geotechnical profession.

In our previous geoteclrnical peer revie'1v ( dated December 10, 2015), we recommended clarification of proposed conveyance and discharge of storm water from the Monte Cresta Drive hun-around. We also reconunended that a design-level geoteclmical investigation be completed for the project prior to approval of specific development plans.

CONCLUSIONS AND RECOMMENDED ACTION
Proposed site development is constrained by steep slopes, existing fill fftaterials, and very strong seismic ground shaking. The Project Geotechnical Consultant has completed a design-level geotechnical investigation and reconm1ended geoteclrnical design parameters that are consistent with prevailing professional standards.

We agree that proposed single-family residence construction is likely feasible at the subject properly if measures to achieve suitable discharge of site and road drainage are clarified. We note that Romig Engineers has reconunended consideration of the constTuction of a row of stitch piers downslope of the roof water drainage spreader.

Such stitch piers are not depicted on the submitted plans. Also, it is unclear how drainage from the ne,,v Monte Cresta Drive turn-around will be conveyed and discharged. We recommend that the following Items 1 and 2 be satisfactorily addressed prior to geoteclmical approval of specific site development plans:

1. Street and Site Drainage - The Project Civil Engineer should clarify the proposed conveyance and discharge of storm water collected at the proposed Monte Cresta Drive turn-around. The Project Geoteclmical Consultant should evaluate the proposed position and design of site residential drainage discharge with respect to potential erosion or other adverse slope impacts and provide recontmendations as warranted. The position of the line of stitch piers near the drainage discharge should be depicted in plan view. Any proposed discharge of sh·eet drainage across the subject property should be evaluated from a geotechnical perspective.

2. Driveway Coordination - It appears that the proposed turnaround/cul-de-sac design should be coordinated with plans for driveway consh"uction extending from the northern portion of the turn-around (providing access to upcoming new Campbell
residence). Turn-around design provisions to acc01ru11odate this future driveway to the north should be clarified on the project Civil Design Plans.

Appropriate documentation and revised plans to address the above two items should be submitted to the City for review by the City Engineer and City Geoteclmical Consultant.

design provision to accommodate a planned future driveway from the north (Campbell residence). In addition, we recommended that the Project Geotechnical Consultant evaluate proposed residential and street drainage discharge with respect to potential adverse slope impacts.

RECENT SUBMITT ALS
The Project Civil Engineer has depicted a proposed street drainage discharge system that conveys collected water from a new street drop inlet via a 6-inch diameter pipe to a pop-up bubbler and bioretention area located across an approximate 40 percent slope. Water is then drained via a 4-inch pipe to a shallow gravel basin (2 foot thick blanket of drain rock overlain by native soil) with an unspecified length and width (size stated to accorn.modate · a 10-year storm event), The Project Geoter:h_.,.1ical Consultant indicates that Civil Plans reflect the intent of geotechnical report recommendations, but we note that these recommendations do not appear to address discharge of street drainage.

CONCLUSIONS AND RECOMMENDED ACTION
The Project Geotechnical Consultant has adequately addressed our comments about control and discharge of drainage around the proposed new residence. However, it is not clear if the proposed street drainage discharge (across steep slopes) will result in erosjon or adverse slope stability impacts and whether this risk has been fully evaluated. We recommend that the following two Items be satisfactorily addressed prior to geotechnical approval of design measures associated the proposed new street turnaround area.

1. Civil Design Clarification - If the concept of a shallow gravel basin is deemed acceptable by the Project Geotechnical
Consultant, then the dimensions of this facility (to accommodate the design storm event) should be calculated and specified, and illustrated on project plans. To reduce the potential for clogging of 5treet storm draimigp pipes; �Ne suggest 11�"' of an nversjz�d pipe be considered along with avoidance of a pop-up bubbler. The use of a 4-inch diameter pipe to convey water to the gravel basin should be re-evaluated. Updated drainage details should be prepared.

2. Geotechnical Street Drainage Evaluation - The Project Geotechnical Consultant should coordinate with the Project Civil Engineer to develop a proposed system for street drainage discharge with a low potential for adverse erosion and slope instability impacts. The potential for concentrated drainage discharge across steep slopes to trigger slope instability with offsite impacts should be evaluated and minimized by the final COTTON, SHIRES AND ASSOCIATES, INC. 473

the potential for adverse impacts to slope stability caused by discharge of sheet drainage and bioretention area and to update conclusions regarding the feasibility of the Monte Cresta Drive through road.

RECENT GEOTECHNICAL EVALUATIONS
The Project Geotechnical Engineer has evaluated the bioretention design and proposed revised cul-de-sac drainage discharge. The Consultant has rec01mnended some relatively minor design modifications but does not object to the basic method of drainage discharge. During a recent field meeting, the Consultant indicated the potential benefits of adding an upslope percolation/ detention struchue with a metered water release to the bioretention area. In our opinion, this supplemental drainage conlrnl element appears to be a benefit to the overall drainage system design and should be implemented to reduce peak water flow to the bioretention facility.

Regarding the through road concept; the consultant has inspected the existing w1paved road alignment and slope conditions. Evidence of on-going and recent slope creep and mass wasting were observed, along with enlargement of erosional features.

In general, slope conditions impacting the through road remain very similar to those observed in 2008. We concur with the Consultant that the through road remains impractical and economically very costly because of very significant landslide constraints.

CONCLUSIONS AND RECOMMENDED ACTION
Based on our reviev,, of referenced documents and over recent site inspection, we concur with the Project Geotecluucal Consultant that consh·uction of the Monte Cresta Drive through road remains impractical and economically very costly because of significant landslide consh·aints. We reconm1end that drainage plans for collection and dispersal of water from the viciluty of the proposed cul-de-sac be updated (per Romig Engineers geotecluucal reconunendations) and consideration be given to adding percolation and detention design elements upslope of the currently proposed bioretention basin.

We h·ust that the above e aluations satisfactorily address Citv geoteclu1ical peer review needs at this rune. Please contact us for any necessary supplemental project e aluations.

consideration of dispersal and detention design elements suggested by the Project Geotechnlcal Consultant.

The cunently proposed storm water runoff design includes collection of water from the cul-de-sac with two drop inlets, detention of collected water (volume and location of detention facility not depicted), conveyance of water in a 4-inch diameter pipe along an existing easement near the eastern property line (easement not illustrated), and dispersal of the collected water via a 24-foot wide rip rap level spreader in the southeastern portion of the property above very steep cut slopes. We understand that an easement may be required for the above noted spreader and for the portion of the street storm water drainage pipe located within the Kraft property. Project civil plans indicate consh·uction of concrete stitch piers downslope of the spreader if required by the Project Geotechnical Consultant. The Consultant has recommended specific revisions to rip rap placement design adjacent to the level spreader in order to more securely key placed rock into the slope.

CONCLUSIONS AND RECOMMENDED ACTION
We understand that proposed discharge of collected sh·eet storm water on a private property is not consistent with City Public Works design standards. We note that the proposed spreader for cul-de-sac water discharge is located within an area of mapped 1960s vintage fill materials (potential stability concern) and above very steep cut slopes. While we understand that upslope catch basins and flow metering are designed to reduce discharge rates to the spreader, it is not clear were excess water will flow after the limited detention capacity is filled. We are concerned about impacts of 50- year or greater storm events that may exceed the capacity of the 4-inch diameter pipe.

In our opinion, the proposed discharge location and design is not appropriate for collected street storm water runoff and we do not recommend geotechnical approval of the design proposal. We recommend that that water collected storm water runoff from roadways be conveyed and discharged in accordance with City Public Works standards, and that discharge of such water be avoided on, or immediately above, very steep slopes. Water discharge sh·uctures should be avoided that direct concenh·ated flow onto slopes underlain by existing fill materials. We do not have other objections to submitted project geotechnical design recommendations or other proposed improvements beyond the above storm water control comments.

PROJECT SUMMARY AND HISTORY
Based on our review of the project plans and geotechnical study report provided by your office, it is our understanding that the applicant proposes to construct a new three-story, single-family residence with driveway on the subject property at the existing, developed northern end of Monte Cresta Drive north of the intersection of Monte Cresta Drive and Barclay Way. Access to the residence would be via a short extension of the existing terminus of Monte Cresta Drive to a new paved cul-de-sac on the north side of the new residence to provide fire truck access to the project.

The project would also include new site infrastructure and utilities, and associated landscaping and drainage systems.
484
Atlas Project No. 91-57787-A1
December 23, 2021
3 The subject property is on the southern side of the unpaved extension of Monte Cresta Drive opposite the paved driveways to the existing residences with addresses of 2824 and 2828 Monte Cresta Drive. At the time of our site reconnaissance, the lot was observed to slope downward toward the rear yard of a residential property at 2810 Alhambra Drive, and was undeveloped, with a few large trees. The 2016 Romig report indicated the presence of a wedge-shaped fill along the southern edge of the Monte Cresta Drive right-of-way, as well as a thin layer of 1960s-vintage undocumented fill in the eastern portion of the property. The fill associated with the grading of the Monte Cresta right-of-way was to be replaced by engineered fill as required during cul-de-sac and related retaining wall construction, and the undocumented fill along the eastern side of the property was not to be relied upon for foundation support.

The information reviewed indicated this project was originally submitted for geotechnical peer review by CSA in 2015 and has gone through several iterations of peer review. CSA’s most recent peer review letter, written in July 2018, indicated that the civil design review plans submitted by BKF at the time (plans dated May 15, 2018) showed collected street storm water from the cul-de-sac would be discharged onto the existing slope via a rip rap spreader, which CSA said was not consistent with City design standards. CSA’s outstanding comments per their most recent letter were (1) that collected street water runoff cannot be discharged onto private property, and that the project be resubmitted with street runoff conveyed and discharged according to City standards; and (2) that any discharge collected on the property is not discharged onto slopes underlain by existing fill materials (i.e., the undocumented thin fill on the eastern side of the property).

Subsequent to CSA’s most recent review, revised civil plans by BKF dated October 10, 2019 were submitted to the City for review. In addition, BKF submitted a technical memorandum dated August 10, 2021 stating that proposed new stormwater flows generated by the project (0.54 cubic feet per second [cfs], consisting of 0.40 cfs off-site flow and 0.14 cfs on-site flow) can be adequately accommodated by the City’s DI-4280, the proposed point of conveyance of the additional project runoff. Romig submitted a plan review letter dated November 8, 2021, where they indicated their opinion that the plans show that storm water runoff from the driveway and predevelopment runoff that exceeds the pre-development runoff will be discharged onto Monte Cresta Drive, and that the most recent reviewed civil plans are in accordance with their geotechnical recommendations and supplemental information discussed with the project team.

COMMENTS
Based on the reviewed documents, we have the following comments:
• On-Site Drainage: As noted in this letter, project geotechnical engineer Romig has issued a civil plan review certification letter required as part of the City’s plan review process.

The submitted plans show a sump pit and pump with erosion control blanket and stitch piers downslope of the residence which is shown as for the collection and disposition of collected stormwater flow generated directly within the limits of the property. The system appears to be located outside the area mapped by Romig as underlain by the thin undocumented fill layer, and thus satisfies the CSA comment on not directly discharging collected stormwater flow onto undocumented fill.
485
Atlas Project No. 91-57787-A1
December 23, 2021
4 The design review plans lack detail on this on-site drainage system, and prior to final approval of the civil plans, details of this system including appropriate cross sections should be provided for review by the City and Romig.
• Off-Site Drainage: Information provided by BKF infers and the Romig letter indicates that all increased stormwater runoff from the project, including collected stormwater on the culde-sac and the paved driveway would be discharged onto the paved street and drain to City DI-4280, thus satisfying the CSA comment that City requirements state flows from City streets cannot discharge onto private properties. The City at its option may want to require more direct documentation from Civil Engineer BKF that this is indeed the case.

Dear Mr. Gill:

In accordance with your request, Atlas Technical Consultants LLC (Atlas) has reviewed for the City of Belmont (City) the most recently submitted documentation regarding the construction of the proposed Kraft Residence and development of a new cul-de-sac terminus of Monte Cresta Drive in Belmont, California. Atlas previously performed a review of this project, the results of which were presented in our letter to Mr. Anwar Mirza of the Public Works Department, dated December 23, 2021.

Our current review included the following scope of work:
 A review of a Technical Memorandum, Kraft Residence – Storm Drain Impact Study, for the project prepared by BKF Engineers (BKF) for the City dated January 3, 2022.  A review of civil plans prepared by BKF, Sheets C0.0 through C5.0, C0.1, C5.1, and C6.0 through C6.2 (11 sheets), dated November 6, 2021.
 Kraft Resubmittal Comment Letter issued by City dated February 4, 2022, with attached review letter by Ruggeri-Jensen-Azar dated January 31, 2022 (includes 3rd submittal comments).

COMMENTS
Based on the reviewed documents, we have the following comment:
 Revised Civil Plans and On-Site Drainage Comment (12-23-22 Letter): The revised civil plans by BKF dated November 6, 2021, do not appear to differ from the previously reviewed civil set dated October 20, 2019, with respect to on-site drainage details of the sump pump discharge system, particularly at the discharge point onto the slope. We had recommended that additional design detail of the system be provided by the applicant’s civil engineer in our December 23, 2021, review letter. However, in our opinion, if the City is satisfied that the most recently submitted civil plans meet its requirements for approval for construction of the project, and that such details can be worked out during construction with the GEORs (Romig’s) approval, Atlas has no further comments to be addressed. 487

SUMMARY
This report presents the results of an assessment of existing or potentially occurring biological constraints to the construction of a single‐family home on a parcel of land located in the City of Belmont, San Mateo County. This Biological Resource Assessment (BRA) is intended to assist the lead agency (City of Belmont) in evaluating the potential biological impacts resulting from the proposed project. pursuant to the statutes and guidelines of the California Environmental Quality Act (CEQA). The proposed project calls for the construction of a single‐family residence on an undeveloped parcel of land with an area of 0.09 ha (0.22 ac).

Plant communities and habitats occurring within the BSA are characterized as anthropogenic, chamise chaparral, coast live oak woodland, coyote brush scrub, non‐ native annual grassland, and ruderal. Of these, anthropogenic, coast live oak woodland, non‐native annual grassland and ruderal habitats occur within the project footprint. No special‐status natural communities or land features (e.g., wetlands, streams, riparian habitat) occur within the BSA and none would be impacted by project implementation. No impact avoidance, minimization or mitigation measures are warranted.

A total of 92 special‐status plant species have been recorded from the nine 7.5‐minute USGS quadrangles including and surrounding the BSA. The potential for occurrence of all 92 target species can be ruled out due to a lack of suitable habitat, lack of suitable soils, geographic location of the BSA relative to known occurrences, or that the fact that they would have been detectable during the present survey. No impact avoidance, minimization or mitigation measures are warranted and no further surveys or analysis related to special‐status plant species are necessary.

A total of 85 special‐status animal species have been recorded in the nine 7.5‐minute USGS quadrangles including and surrounding the BSA, 18 of which have been recorded from within a 4.8 km (3 mi) radius of the project site. Based on the existing habitats on site and its geographic location, the occurrence of 75 of the target species can be ruled out entirely based on absence of suitable habitat, the site’s location outside of the species known range, or absence of regional species occurrences. A total of five special‐status animals are considered to have a potential to occur in the BSA.

These include Allen’s hummingbird, CA thrasher, oak titmouse, spotted towhee, and San Francisco dusky‐footed woodrat. If present at the time of construction, project implementation could impact these species. Impacts to these resources would be considered significant pursuant to the statutes and statutes and guidelines of CEQA.

However, with the incorporation of the impact avoidance, minimization and/or mitigation measures outlined in this report impacts would be reduced to a less‐than significant level pursuant to the statutes and guidelines of CEQA. 492

1.0 INTRODUCTION
This report presents the results of an assessment of existing or potentially occurring biological constraints to the construction of a single‐family home on a parcel of land located in the City of Belmont, San Mateo County. This Biological Resource Assessment (BRA) is intended to assist the lead agency (City of Belmont) in evaluating the potential biological impacts resulting from the proposed project. pursuant to the statutes and guidelines of the California Environmental Quality Act (CEQA). The report provides background and site‐ specific information pertaining to special‐status plant and wildlife species and other regulated biological resources (e.g., wetlands, streams, natural communities, and protected trees) which may represent constraints to the proposed activity.

1.1 Project Background and Description
The subject property is located at the western terminus of Monte Cresta Drive just west of the residence located at 2817 Monte Cresta Drive (Figures 1 and 2). The parcel (APN 043‐ 165‐180) has a gross area of 900 m2 (9682 ft2). The proposed two‐story home would have a gross floor area of 305 m2 (3283 ft2). The conceptual plans for the home are shown in Figure

3. Previous analyses regarding biological resources covering the subject parcel were conducted in support of the approved Monte Cresta Drive Road Improvement Project. These include a biological assessment and update (Wood Biological Consulting, 2004, 2012), an evaluation of habitats for the endangered mission blue butterfly (Wood Biological Consulting, 2009), and an Initial Study and Mitigated Negative Declaration (City of Belmont, 2011).

2.2 Data Sources
Lists of potentially occurring special‐status plant and animal species1 were compiled based on a review of databases maintained by the California Natural Diversity Database (CNDDB, 2017), the U.S. Fish and Wildlife Service (USFWS, 2017), and the California Native Plant Society (CNPS, 2017). Botanical nomenclature conforms to the Jepson Online Interchange (Jepson Herbarium, no date). Common names of plant species are derived from Calflora (2017). Plant habitat affinities and local distribution information are consistent with Baldwin et al. (2012), Corelli (2011), Corelli and Chandik (1995), Thomas (1961). Nomenclature for special‐status plant species conforms to the California Department of Fish and Wildlife (CDFW2; CDFW 2017a,b).

Nomenclature for common wildlife species conforms to the (CDFW, 2016), with taxonomic nomenclature updates conforming to the American Ornithologistʹs Union and supplements (AOU, 2016) for birds, Jennings (2004) for amphibians and reptiles, and the American Society of Mammologists (ASM, 2016) for mammals. Nomenclature for freshwater and terrestrial invertebrates conforms to the CDFW (2017c) and (Moyle and Davis, 2000) for freshwater, anadromous, and euryhaline fishes. Local information on breeding bird species is based on Bousman (2007). Nomenclature for special‐status animal species conforms to the CDFW (2017c,d).

The classification of vegetation types described herein conforms to Sawyer et al. (2009) and, where applicable, Holland (1986) and Cowardin et al. (1979). Special‐status plant community designations conform to the CDFW (CNDDB, 2017 and CDFG, 2010). Current and historic creek conditions were obtained from the Creek and Watershed Map of San Mateo and Vicinity (Oakland Museum, 2007). Information regarding soils was obtained from the web‐based database Web Soil Survey3, operated by the Natural Resources Conservation Service (NRCS).

2.3 Special‐Status Biological Resources
A literature review was conducted to investigate the potential presence of special‐status biological resources within the BSA. Occurrence summaries were obtained from the following sources:

1. Database queries for the San Mateo, Woodside, Half Moon Bay, San Leandro, Redwood Point, Palo Alto, Hunters Point, San Francisco South, and Montara Mountain 7.5‐minute USGS quadrangles from the available databases (CNDDB, 2017; CNPS, 2017; USFWS, 2017).

1 For purposes of this discussion, the term “species” implies all recognized taxa at the level of species, subspecies or variety.
2 On January 1, 2013, the CA Dept. of Fish and Game (CDFG) changed its name to the CA Dept. of Fish and Wildlife (CDFW); publications are referenced by the name in effect at the time of publication. 3 Available at http://websoilsurvey.sc.egov.usda.gov/App/HomePage.htm 501
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 6

2. An assessment of habitat types and surrounding land uses completed by reviewing recent aerial photographs.

3. A reconnaissance‐level survey by a qualified biologist.

The presence or potential for occurrence of special‐status biological resources within the BSA is based on direct observation or an evaluation of the suitability of existing habitats occurring within the BSA. Suitability is based on familiarity with the specific habitat requirements (i.e., elevation, geology, soil chemistry and type, vegetation communities, microhabitats), geographic distribution, local occurrence records, and the degree of habitat disturbance or alteration. The criteria for assessing the potential for occurrence of special‐ status species are summarized below.

None   Applied to plant and animal species for which suitable habitat is lacking, which are not known to occur locally, or which are thought to be locally extirpated.

Absent Applied to plant and animal species for which suitable habitat is present but which would have been detectable at the time surveys were conducted.

Not Expected   Applied to plant and animal species for which suitable habitat or key habitat elements may be present but which are considered to be of poor quality or are spatially isolated from either known occurrences or areas of suitable habitat. When the existing habitats within the BSA do not coincide with a species’ life history or ecological requirements, its occurrence is not expected.

Possible   Applied to plant and animal species for which suitable habitat or key habitat elements are present within the BSA. The occurrence of these species is either considered likely, or, at the least, its presence cannot be ruled out.

Present   Applied to plant and animal species that were either observed directly or, in the case of animal species, whose presence can be presumed based on detection of diagnostic sign (i.e. tracks, scat, burrows, carcasses, castings, prey remains, etc.).

The conclusions presented in this document are based on a reconnaissance‐level survey performed by biologist Michael Wood on October 8, 2017. All plant and wildlife observations were recorded, and habitats characterized and mapped. 502

2.4 Limitations That May Influence Results
Based on the timing of surveys performed as part of this assessment, the presence or absence of some of the target special‐status plant or animal species cannot be established.

Not all plant species, for example, occurring within the BSA may have been detectable due to flowering phenology and life forms (e.g., bulbs, biennials, and annuals). In addition, some annual plant species present in the seed bank may not germinate in some years due to drought, temperature, or fire regime. Negative findings during site assessments or focused surveys do not necessarily indicate absence unless field surveys conform to agency approved protocols.

A multi‐season floristic survey was not performed as part of this assessment and not all target special‐status plant species would have been identifiable at the time the single survey was performed. However, the survey was performed by a qualified botanist and an assessment of the potential for occurrence of all target plant species was completed.

3.0 SETTING
The BSA is situated near the top of a southwest‐facing slope overlooking San Juan Canyon.

Lands to the south and east of the study area support single family residences. Another line of homes is present immediately downslope along Alhambra Drive.

The study area itself is contiguous with undeveloped slopes of San Juan Canyon and the San Juan Hills. San Juan Canyon is contiguous with the City of San Mateo’s Sugar Loaf Mountain Open Space Preserve and Laurelwood Park. Combined, the park, preserve and canyon occupy well over 122 ha (300 ac) of mostly native, mixed oak woodland, riparian, chaparral, and grassland habitats. San Juan Canyon drains into Laurel Creek, which drains into San Francisco Bay.

The project site has a southwesterly aspect, with elevations ranging from 122‐143 m (400‐460 ft) above mean sea level (msl).

The BSA is mapped as supporting soils classified as Fagan loam, 15‐50% slopes and Orthents, cut and fill – Urban land complex, 5‐75 percent slopes (USDA, 2017b). Neither of these soil units is considered a hydric soil type (USDA, 2017a).

The limits of the BSA are illustrated in Figure 4. Photographs of the BSA and project footprint are presented in Appendix A.

3.1 Plant Communities and Habitats
Plant communities and habitats occurring within the BSA are characterized as anthropogenic, chamise chaparral, coast live oak woodland, coyote brush scrub, non‐native annual grassland, and ruderal. Of these, anthropogenic, coast live oak woodland, non‐ native annual grassland and ruderal habitats occur within the project footprint each is described below. The location and extent of each of these habitats are illustrated in Figure 4.

Anthropogenic Habitat
Anthropogenic habitats are those dominated by plant species introduced by humans and established or maintained by human disturbances or activities (Holland and Keil, 1990).

Some are entirely artificial such as areas under active cultivation (e.g., rowcrops, orchards, vineyards, ornamental landscaping). Others include areas used as rangeland or pasture, and areas influenced by urban or suburban landscaping or plantings. On such sites, the native vegetation has typically been removed by clearing in preparation for cultivation, landscaping, or development. Cleared areas that are planted with or colonized by non‐ indigenous plant species can create distinct communities dominated by annual grasses and forbs, shrubs, or trees. Some of these communities are only perpetuated with direct human intervention such as irrigation or grazing, while have naturalized and are able to persist without artificial means. In some situations, introduced non‐indigenous species invade native habitats, altering the composition of the native understory or canopy, or both.

Anthropogenic habitats within the BSA consist of structures, paving, cleared lands, and maintained ornamental landscaping. Within the boundaries of the subject parcel, a hedge of planted oleander shrubs is present along the northeaster property line.

Landscaping as a habitat is not classified by Sawyer et al. (2009); it would be classified as an upland following Cowardin et al. (1979). Unless found to support special‐status plant or animal species, or as otherwise regulated under local tree or zoning ordinances, impacts to anthropogenic habitats typically would not be regarded as significant pursuant to the statutes and guidelines of CEQA (see discussion in Section 4.1).

Many native and non‐native animal species are well adapted to anthropogenic habitats, while others have benefited greatly from urbanization and anthropogenic effects. These species are attracted by certain resources readily available in anthropogenic settings such as forage, water and shelter while being tolerant of human disturbances such as noise, lighting, and the movement of people and machinery. Many mammals are attracted to human development providing a source of food (e.g., rubbish, garden plants, pet food, and pets themselves).

Mature ornamental trees may support a variety of birds by providing roosting, nesting, and foraging opportunities. Common birds that can nest and roost in such trees include passerines (i.e, perching birds) such as black phoebe, bushtit, CA scrub‐jay CA towhee, 505
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 10 chestnut‐backed chickadee, house finch, house sparrow, mourning dove, northern mockingbird, oak titmouse, and red‐shouldered hawk, among many others. Common mammals likely to occur in this habitat within the BSA include eastern fox squirrel, mule deer, raccoon, striped skunk, and Virginia opossum, among others.

Animal species or their sign4 detected in this habitat during the present wildlife reconnaissance survey include American crow, mule deer, pocket gopher, western scrub‐ jay, and white‐crowned sparrow.

Coast Live Oak Woodland
Coast live oak woodland is typically found on north‐facing slopes and shaded ravines in the southern and inland portions of the State and on more exposed, mesic sites in the north.

This community is dominated by coast live oak, a drought‐resistant evergreen tree growing to 25 m (82 ft) tall. It produces both deep taproots and extensive surface roots. The species frequently occurs in pure, dense stands with a closed canopy. Coast live oak woodland is restricted primarily to the coast side of the State and is distributed from Sonoma County to Baja California. It occurs throughout the outer South Coast ranges and coastal slopes of the Transverse and Peninsular ranges, from sea level to about 1200 m (4000 ft) in elevation.

Coast live oak woodlands can be found on alluvial terraces, canyon bottoms, stream banks, slopes, and flats, growing on deep, sandy or loamy soils with high organic matter content (Sawyer, et al., 2009).

Membership in this alliance requires that coast live oak trees comprise over 50 percent relative cover in the tree canopy, or, if CA bay is present, less than 33 percent relative cover in the tree canopy. The California Fish and Game Code (CFGC) defines oak woodland as “an oak stand with a greater than ten percent canopy cover or that may have historically supported greater than ten percent canopy cover”.5 Stands with a mixed tree layer may include as co‐dominant species arroyo willow, big‐leaf maple, black oak, black walnut, blue oak, CA bay, CA buckeye, CA sycamore, Coulter pine, Engelmann oak, madrone, and valley oak (Sawyer, et al., 2009). Coast live oak woodland has been assigned a rarity ranking of G5/S4, which is considered secure statewide and is does not have a high priority for inventory in the CNDDB (CDFG, 2010).

Within the BSA, coast live oak woodland consists of two relatively small, isolated stands, one of which overlaps onto the subject parcel. This stand is dominated by only a few mature coast live oak trees of relatively small stature. The understory is sparse, supporting non‐ native grasses, poison oak, and coyote brush.

4 Animal signs include tracks, vocalization, scat, white‐wash, feathers, fur, shed skin, nests, burrows, prey remains, odor, and dead individuals.
5 CFGC § 1361(h)
506
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 11 On site, coast live oak woodland conforms to the Quercus agrifolia Woodland Alliance as described by Sawyer, et al. (2009; CA vegetation code 71.060.02 and Holland code 71160).

This plant association is classified as an upland habitat following Cowardin, et al. (1979).

Unless protected under local policies or ordinances or found to support special‐status plant or animal species, impacts to coast live oak woodland in upland or non‐riparian settings would not typically be regarded as significant under the statues and guidelines of CEQA (see discussion in Section 4.1).

In general, oak woodlands are considered essential for the conservation of many bird and mammal species (USDA, 1999; Block et al., 1990). Over 300 vertebrate species are known to use oak trees. Important components of oak habitats to wildlife include acorns, snags, trunk cavities, and downed wood/litter. As a seasonal food, acorns play an important role in the survival of many animal species (Tietje, 1990). Mature oak trees frequently bear snag limbs and trunk cavities, which are provide opportunities for nesting, roosting, foraging, caching and wintering by a wide variety of birds and bats. Acorns constitute a significant portion of the diet of numerous birds and mammals. Numerous species of raptors (birds‐of‐prey) are associated with coast live oak woodland.

Coast live oak woodland provides foraging, nesting, cover, and movement habitat for a variety of other animal species. California newt and CA slender salamander can be found underneath surface litter, such as downed wood, leaf litter and bark. Pacific treefrog and western toad also might occur in oak woodland if suitable spawning pools are nearby.

Reptiles often found in oak woodland include alligator lizard, common kingsnake, gopher snake, terrestrial garter snake, western fence lizard, and western skink.

Avian insect eaters, such as bushtit, chestnut‐backed chickadee, dark‐eyed junco, and oak titmouse feed off of the foliage of oaks. Bark gleaner species, such as brown creeper, Nuttall’s woodpecker, and white‐breasted nuthatch. Other species such as acorn woodpecker, CA scrub‐jay, and Stellerʹs jay feed on insects as well as acorns. California quail and CA towhee are ground foliage gleaners. Great horned owl, red‐shouldered hawk, red‐tailed hawk may forage on small mammals in adjacent grasslands from the protection of the canopy of oak woodlands while Cooper’s hawk and sharp‐shinned hawk may hunt small birds among the tree canopy.

Mammals associated with coast live oak woodland include the native western gray squirrel and the ubiquitous non‐native eastern fox squirrel, which forage and nest in the canopy. The long‐tailed weasel hunts for shrews and CA vole on the ground. Bobcat, dusky‐footed woodrat, gray fox, mountain lion, mule deer, raccoon, and Virginia opossum are also likely to utilize the understory of this community (e.g., poison oak, blackberry bushes) for shelter, hunting and for browse. Mature oaks and snags are important habitat features because they provide nesting and roosting areas for a variety of special‐status species of bats that occur in this region, including long‐eared myotis, long‐legged myotis, pallid bat, and Yuma myotis (Whitaker, 1997).
507
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 12 Animal species or their sign detected in this habitat during the present wildlife reconnaissance survey include Anna’s hummingbird, CA towhee, mule deer, and western scrub‐jay.

Non‐native Annual Grassland
Non‐native grasslands are generally found in open areas in valleys and foothills throughout coastal and interior California (Holland, 1986). They typically occur on soils consisting of fine‐textured loams or clays that are somewhat poorly drained. This vegetation type is dominated by non‐native annual grasses and weedy annual and perennial forbs, primarily of Mediterranean origin, that have replaced native perennial grasslands, scrub and woodland habitats as a result of human disturbance. Scattered native wildflowers and grasses, representing remnants of the original vegetation may also be common.

Within the BSA, non‐native annual grassland occurs on the upper slopes where it has been historically impacted by grazing, grading, road and home construction, and earth movement. It is dominated by such characteristic non‐native species as false‐brome, perennial ryegrass, rattail fescue, ripgut brome, and wild oats; co‐dominant non‐native annual forbs include Italian thistle, red‐stemmed filaree, rose clover, and yellow starthistle, among others. The native perennial bunchgrass foothill needlegrass is relatively common on site.

On site, areas of non‐native annual grassland most closely conform to Annual Brome Grasslands (Bromus [diandrus, hordeaceus]‐Brachypodium distachyon Semi‐Natural Herbaceous Stands), as described in Sawyer, et al. (2009). It has been described as Non‐native Grassland by Holland (1986; Holland code 42200) and the CDFW (CA vegetation code 42.026.00). Non‐ native annual grasslands would be classified as an upland following Cowardin, et al. (1979).

As a common, widespread and non‐natural plant association, on‐native annual grassland has no global or State rarity ranking (Sawyer, et al., 2009; CDFG, 2010). Unless found to harbor special‐status species, impacts to non‐native annual grassland would not typically meet the significance criteria pursuant to the statutes and guidelines of CEQA (see discussion in Section 4.1).

Grasslands may support a variety of reptiles and amphibians including alligator lizard, common kingsnake, gopher snake, northern Pacific rattlesnake, ring‐necked snake, western fence lizard, and western skink, among others. This habitat also attracts avian seed‐eating and insect‐eating species of birds and mammals. California quail, mourning dove, and western meadowlark are a few seed‐eaters that nest and forage in grasslands. Insect‐eaters such as barn swallow, CA scrub‐jay, and western bluebird commonly forage in grasslands.

In the project region, burrowing owl may nest and forage in grasslands where the vegetation is kept low by grazing or regular mowing.

Grasslands are important foraging grounds for aerial and ground foraging insect‐eating bat species in the genus Myotis. A large number of other mammal species such as black‐tailed 508
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 13 jackrabbit, Botta’s pocket gopher, brush rabbit, CA ground squirrel, CA vole, and deer mouse also reside or forage within grasslands. Small rodents attract raptors (birds of prey) such as barn owls and great horned owls that hunt at night, as well as day‐hunting raptors such as golden eagle and red‐tailed hawk. Mule deer use grassland for grazing and, if the grass is tall enough, for bedding down at night. American badger, coyote, gray fox, and red fox will dig dens in grasslands for the rearing of young and daytime refuge, and, along with bobcats, will hunt in grasslands.

Animal species or their sign detected in this habitat during the present survey include brush rabbit, mule deer, western fence lizard and white‐crowned sparrow.

Ruderal Habitat
Ruderal habitat is that from which the native vegetation has been completely removed by grading, cultivation, or other surface disturbances. Left undeveloped, such areas typically become recolonized by invasive exotic species. Scattered native species might recolonize such sites after disturbances have ceased. Ruderal sites are typically dominated by herbaceous species, although scattered woody shrubs and trees may also begin to appear if left undisturbed long enough. Ruderal sites are characteristic of road sides, fallow agricultural fields, vacant lots, and landslides.

Within the BSA, ruderal habitat coincides with areas historically subjected to the highest level of repeat disturbance. These areas occur adjacent to homes, on roadsides and along trails, and where excavated spoils have been deposited. Characteristic non‐native species commonly observed on site include Italian thistle, milk thistle, perennial ryegrass, ripgut brome, and wild oats, among others.

Ruderal habitat is not specifically described by Sawyer, et al. (2009); it would be classified as upland following Cowardin, et al. (1979). As a non‐native plant association, ruderal habitat has no global or State rarity ranking. Unless found to support special‐status plant or animal species, or as otherwise regulated features such as drainages or water bodies, impacts to ruderal habitat would not be regarded as significant pursuant to the statutes and guidelines of CEQA (see discussion in Section 4.1).

Ruderal sites commonly support a variety of passerines (perching birds) that forage on disturbed ground or among the scattered trees and shrubs, and may include Brewer’s blackbird, CA scrub‐jay, European starling, house finch, house sparrow, mourning dove, and northern mockingbird, among others. Fossorial (i.e., burrowing) mammals such as Botta’s pocket gopher and CA ground squirrel are also expected, along with brush rabbit and such rodents as deer mouse, CA vole, and Norway rat. Mammals that are naturally habituated to human habitation and activities include mule deer, raccoon, striped skunk, and Virginia opossum. Reptiles that may also be found include alligator lizard and western fence lizard.

3.2 Animal Movement Corridors
Under CEQA, impacts to animal movement corridors are considered significant if a project would interfere substantially with the movement of native resident or migratory fish or animal species or with established native resident or migratory animal corridors, or impede the use of native animal nursery sites. Animal movement corridors are defined as linear habitats that naturally connect and provide passage between two or more large habitats or habitat fragments; they are important for the persistence of animal species overtime. For populations to be viable, animal species must have access to adequate resources. Corridors are used to find suitable forage, nesting and resting sites, mates and for the establishment of new home ranges by dispersing juveniles. In addition, corridors for dispersal within breeding populations will decrease the likelihood that extirpations will occur in subpopulations. Even where patches of pristine habitat are fragmented, as commonly occurs with riparian vegetation, the movement of animals between populations is facilitated through habitat linkages, migration corridors and movement corridors.

Animal movements includes migration (i.e., usually one direction per season), inter‐ population movement (i.e., long‐term genetic exchange) and small travel pathways (i.e., daily movement within an animal’s home range). Daily movement patterns define an animal’s home range where activities such as foraging, resting and conspecific (individuals of the same species) interactions occur. Generally, longer movements, usually by dispersing individuals connect breeding populations, permit gene flow between subpopulations.

Corridors generally provide adequate habitat for animals to disperse until reaching an area large enough to establish home ranges. Corridors are different depending on the type of organism; a corridor for a butterfly or bird may be a series of “stepping stones” of suitable habitat, while a terrestrial vertebrate may require a continuous band of suitable habitat for successful movement. Habitat loss, fragmentation, and degradation resulting from a change in land use or habitat conversion can alter the use and viability of corridors.

The BSA encompasses residential neighborhoods at the interface of undeveloped lands of San Juan Canyon and the adjacent Sugar Loaf Open Space Preserve and Laurelwood Park. These lands are connected to the much large open space surrounding Crystal Springs Reservoir and the State Fish and Game Refuge. Despite the presence of Interstate 280, San Juan Canyon is basically contiguous with the extensive open space of the San Mateo Peninsula.

For this reason, it is expected that San Juan Canyon supports a high level of wildlife abundance and diversity. However, the subject parcel is at the periphery of developed lands and, as such, is not in the pathway of wildlife movements between connected open space lands. Development of the parcel would have no significant adverse effects on the movements of terrestrial wildlife.

4.0 SPECIAL‐STATUS BIOLOGICAL RESOURCES
Certain natural plant communities, wildlife habitats and landscape features are considered to have special‐status due to their restricted occurrence in the State, their tendency to support special‐status plant or animal species, or because impacts are restricted or otherwise regulated under federal, State, or local laws or ordinances. These are discussed below.

4.1 Special‐Status Natural Communities and Landscape Features Special‐Status Natural Communities
Special‐status natural communities are those that are considered rare in the region, support special‐status plant or animal species, or receive regulatory protection under the Clean Water Act (CWA), Lake and Streambed Alteration Program (LSAP), and/or the Porter‐ Cologne Water Quality Control Act (PCWQCA). A number of communities have been designated as rare and these communities are given the highest inventory priority (CNDDB, 2017; CDFG, 2010). Vegetation alliances given a rarity ranking of G1/S1, G2/S2 or G3/S3 are considered to be of high inventory priority by the CNDDB; impacts would be considered significant pursuant to CEQA. Alliances ranked as G4/S4 or G5/S5 are generally considered common enough to not be of concern; impacts would not normally be considered as significant pursuant to CEQA (rarity rankings are explained in Appendix D).

Wetland and riparian habitats are considered by federal and State regulatory agencies to represent a sensitive and declining resource. Wetland and riparian habitats can serve significant biological functions by providing nesting, breeding, foraging, and spawning habitat for a wide variety of resident and migratory animal species. No wetland or riparian habitats are present on the subject parcel or in the BSA.

Special‐status natural communities recorded from the project region include Northern Coastal Salt Marsh, Northern Maritime Chaparral, Serpentine Bunchgrass Grassland, Valley Needlegrass Grassland and Valley Oak Woodland (CNDDB, 2017). None of these or any other special‐status natural communities are present within the BSA and none would be impacted as a result of project implementation. No impact avoidance, minimization or mitigation measures are warranted.

Special‐Status Landscape Features
In addition to wetlands and riparian habitats, discussed above, non‐vegetated channels, drainages, swales, ponds and lakes, and other bodies of water also receive regulatory protection under federal, State or local laws or policies.

The U.S. Army Corps of Engineers (USACE) and U.S. Environmental Protection Agency (USEPA) assert jurisdiction over “non‐navigable tributaries of traditional navigable waters (TNW) that are relatively permanent where the tributaries typically flow year‐round or have 511
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 16 continuous flow at least seasonally (e.g., typically three months)” and “wetlands that abut such tributaries” (USEPA/USACE, 2008). Such areas are referred to collectively as “Waters of the U.S.”6 The extent of USACE jurisdiction corresponds to the Ordinary High Water Mark (OHWM).7 As such, the placement of fill below the OHWM would be regulated pursuant to the CWA8 and would fall under the jurisdiction of the USACE and the San Francisco Regional Water Quality Control Board (RWQCB).

The CDFW also asserts jurisdiction over water courses and water bodies. Pursuant to the LSAP9, entities must notify the CDFW prior to commencing any of the following activities:
 Substantially divert or obstruct the natural flow of any river, stream or lake10;  Substantially change or use any material from the bed, channel or bank of any river, stream, or lake; or
 Deposit debris, waste or other materials that could pass into any river, stream or lake.

The extent of CDFW jurisdiction extends to the top of bank or beyond if an overhanging riparian canopy is present.

No special‐status landscape features are present within the BSA and none would be impacted as a result of project implementation. No impact avoidance, minimization or mitigation measures are warranted.

6 As defined in 40 CFR 230.3(s), Waters of the U.S. include:
 All waters that are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters that are subject to the ebb and flow of tide;  All interstate waters, including interstate wetlands;  All other waters, such as interstate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, vernal pools, wet meadows, playa lakes, or natural ponds, the use, degradation, or destruction of which could affect interstate or foreign commerce;  Tributaries of the above;
 Territorial seas; and
 Wetlands adjacent to waters defined above.

Although isolated wetlands no longer fall under USACE jurisdiction, impacts to isolated wetlands continue to be regulated under State law (see below).
7 The OHWM is the line on the shores established by the fluctuations of water and indicated by physical characteristics such as: a clear natural line impressed on the bank; shelving; changes in the character of the soil; destruction of terrestrial vegetation; the presence of litter and debris; or other appropriate means that consider the characteristics of the surrounding areas (USACE, 2006). 8 CWA § 404 and CWA § 401
9 CFGC §§ 1600, et seq.
10 These include those that are episodic (they are dry for periods of time) as well as those that are perennial (they flow year round). This includes ephemeral streams, desert washes, and watercourses with a subsurface flow. It may also apply to work undertaken within the flood plain of a body of water. 512

4.2 Special‐Status Plant Species
Special‐status plant species include all plant species that meet one or more of the following criteria:11
 Listed or proposed for listing as Threatened or Endangered under the federal Endangered Species Act (FESA) or candidates for possible future listing as Threatened or Endangered under the FESA.12
 Listed13 or candidates for listing by the State of California as Threatened or Endangered under the California Endangered Species Act (CESA).14 A species, subspecies, or variety of plant is endangered when the prospects of its survival and reproduction in the wild are in immediate jeopardy from one or more causes, including loss of habitat, change in habitat, over‐exploitation, predation, competition, disease, or other factors.15 A plant is threatened when it is likely to become endangered in the foreseeable future in the absence of special protection and management measures.16
 Listed as Rare under the California Native Plant Protection Act (CNPPA).17 A plant is Rare when, although not presently threatened with extinction, the species, subspecies, or variety is found in such small numbers throughout its range that it may be endangered if its environment worsens.18  Meet the definition of Rare or Endangered under CEQA.19 Species that may meet the definition of Rare or Endangered include the following:
o Species considered by the CNPS to be “rare, threatened or endangered in California” (Lists 1A, 1B and 2);
o Species that may warrant consideration on the basis of local significance or recent biological information;
o Some species included on the California Natural Diversity Database’s (CNDDB) Special Plants, Bryophytes, and Lichens List.
 Locally significant species, that is, a species that is not rare from a statewide perspective but is rare or uncommon in a local context such as within a county or region20 or is so designated in local or regional plans, policies, or ordinances

11 This definition is provided in CDFG (2009).

Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 18 (CEQA Guidelines21). Examples include a species at the outer limits of its known range or a species occurring on an uncommon soil type.

In addition, plant species have been assigned global and State rarity rankings (rarity rankings are explained in Appendix D). Species ranked as S1, S2, or S3 are considered to be critically imperiled, imperiled or vulnerable to extinction within the boundaries of the State (CDFW, 2017a). As such, these species may be considered to meet the criteria for listing as endangered, threatened or rare under CESA.22 Species ranked as S4 or S5 are generally considered common enough to be secure and not at risk of extinction. Impacts on special‐ status plants species, as thusly defined, would be regarded as significant pursuant to CEQA23 and should be addressed in environmental review documents.24 A total of 92 special‐status plant species have been recorded from the nine 7.5‐minute USGS quadrangles including and surrounding the BSA (CNPS, 2017; CNDDB, 2017; USFWS, 2017). A total of 19 special‐status plant species have been recorded from within a 4.8 km (3 mi) radius of the BSA; six have been recorded from within 1.6 km (1 mi) of the BSA (Figure 5).

The potential for occurrence of all 92 of the target species can be ruled out due to a lack of suitable habitat, lack of suitable soils, geographic location of the BSA relative to known occurrences, or that the fact that they would have been detectable during the present survey.

No impact avoidance, minimization or mitigation measures are warranted and no further surveys or analysis related to special‐status plant species are necessary.

A list of all special‐status plant species evaluated as part of this analysis can be found in Appendix B. Rarity rankings are explained in Appendix D.

4.3 Special‐Status Animal Species
Special‐status animal species include listed as Endangered, Threatened, Rare, or as Candidates for listing under the FESA (USFWS, 2017) or CESA (CDFW, 2017d). Other species regarded as having special‐status include special animals, as listed by the CDFW (2017c). Additional bird species receive protection under the Bald and Golden Eagle Protection Act (BGEPA)25, the Migratory Bird Treaty Act (MBTA)26 and the Migratory Bird Treaty Reform Act (MBTRA)27. The USFWS maintains a list of bird species of conservation concern (BCC) which includes species of migratory nongame birds that could become candidates for listing under FESA (USFWS, 2008).

Additional definitions are given in CEQA.38 Impacts on special‐status animal species, as thusly defined, may qualify as significant pursuant to the statutes and guidelines of CEQA.

A total of 85 special‐status animal species have been recorded in the nine 7.5‐minute USGS quadrangles including and surrounding the BSA (CNDDB, 2017; USFWS, 2017). A total of 18 special‐status animal species have been recorded from within a 4.8 km (3 mi) radius of the BSA; of these, only five have been recorded from within a 1.6 km (1 mi) radius of the BSA (Figure 6).

Based on the existing habitats on site and its geographic location, the occurrence of 75 of the target species can be ruled out entirely based on absence of suitable habitat, the site’s location outside of the species known range, or absence of regional species occurrences.

Although marginally suitable habitat is present within the BSA for another five target species (American badger, burrowing owl, Nuttall’s woodpecker, rufous hummingbird, and San Francisco Bay Area leaf‐cutter bee), their occurrence is not expected due to the site’s level of disturbance, habitat alteration, or geographic location relative to know occurrences.

No federally or State‐listed animal species are considered to have any potential to occur on site or to be adversely affected by project implementation.

Based on the presence of suitable or marginally suitable habitat, a total of five target special‐ status animals are considered to have a potential to occur on site. These include Allen’s hummingbird, CA thrasher, oak titmouse, spotted towhee, and San Francisco dusky‐footed woodrat. These species, along with other high‐profile species known from the region, are described below. A list of all special‐status animal species evaluated as part of this analysis can be found in Appendix C. An explanation of rarity status codes is provided in Appendix D.

Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 22 Federal/State‐Listed, Proposed, Candidate, or Fully Protected Fish and Animal Species Mission Blue Butterfly
Regulatory Status: FESA: Endangered; CESA: none; CDFW: Special Animal; Global/State rarity ranking: G5T1/S1; Xerces: Candidate.

Description: The mission blue butterfly (Plebejus icarioides misionensis) is a member of the gossamer‐winged butterfly family (Lycaenidae) and is one of several subspecies of the Boisduval’s blue butterfly. The subspecies is non‐migratory and is restricted to grasslands within the coastal fogbelt of San Mateo County, San Francisco County, and Marin County.

The subspecies is a small butterfly with wingspan approximately 2.5‐3.8 cm (1‐1.5 in) across.

Males and females have very different wings. The tops of malesʹ wings are iridescent blue and lavender. Femalesʹ  wings are dark brown with blue at the base. In both males and females, wing edges are black. They have fringes made of long white hair‐like scales. The undersides of the wings are whitish with small gray and larger black circles. There are no spots on the upper surfaces of the wings. The body of the male is dark bluish brown.

Mission blue butterflies can be seen flying around from about late March to early July, and adults live about a week. Favored nectar plants include coastal buckwheat, hairy false goldenaster, ookow, Ithurielʹs spear, California phacelia, California horkelia, and a variety of native and non‐native thistles.

Females lay eggs on lupine plants throughout the mating flight. The eggs are laid singly on leaves, stems, flowers and seed pods. The larval host plants include three perennial lupine species; summer lupine, silver lupine, and varied‐color lupine. Eggs hatch after 4‐10 days and the caterpillars hatch and begin feeding on the lupine leaves. The caterpillars go into an extended dormancy (diapause) through late summer, fall and winter, and commence feeding again in the early spring of the following year.  Once the caterpillars reach the fifth and final instar, they pupate for approximately three weeks and then emerge as adults.

Critical Habitat: Critical Habitat has not been designated for the subspecies.

Habitat Suitability and Occurrence Data: Marginally suitable habitat for the mission blue butterfly is present on site and on the grassy slopes of San Juan Canyon. A large stand of the larval host plant, silver lupine, was mapped on lands just to the west of the subject parcel (Wood Biological Consulting, 2009). Based on the current survey, no larval host plants or nectar sources are present on the subject parcel and none would be impacted by the proposed project.

There are no reported occurrences of the mission blue butterfly within 4.8 km (3 mi) of the project site. The closest recorded occurrence of the mission blue butterfly is approximately

8.9 km (5.5 mi) to the northwest at Crystal Spring Reservoir (CNDDB, 2017). No other mission blue observations have been recorded within the general region, and mission blues 518
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 23 have not previously been detected south of Highway 92 or inland (east) of Highway 280.

This is thought to be due to the lack of coastal fog influence, although the open canyons of San Mateo County have not been well studies.

Potential Project‐Related Effects: No suitable habitat for the mission blue butterfly is present on site and the species is presumed to be absent. No impact avoidance, minimization or mitigation measures are warranted.

Other Special‐Status or Locally Rare Animal Species
Allen’s Hummingbird
Regulatory Status: FESA: none; CESA: none; CDFW: Special Animal (nesting); USFWS: Bird of Conservation Concern; Global/State rarity ranking: G5/S4.

Description: Allen’s hummingbird (Selasphorus sasin) is a spring and summer resident found along the coastline from Curry County in southern Oregon to Santa Barbara and the Channel Islands in southern California (Mitchell, 2000). Migration begins early and may depart their wintering grounds in Central Mexico as early as December or January (Mitchell, 2000). Breeding habitat varies in the Bay Area from moist coastal scrub, mixed evergreen forests, riparian corridors, and eucalyptus groves to oak woodlands, chaparral and scrub, where it builds small nests on the branches of trees and shrubs (Mitchell, 2000; Baicich and Harrison, 2005). This species is highly territorial and will aggressively defend its nesting and foraging grounds. Breeding typically begins in February and is commonly double‐brooded due to the extended breeding season (Baicich and Harrison, 2005). Allen’s hummingbird is a confirmed breeder in Santa Clara County (Bousman, 2007).

Critical Habitat: Allen’s hummingbird is not listed under FESA; as such, Critical Habitat has not been designated for the species.

Habitat Suitability and Occurrence Data: Within the BSA, coast live oak woodland provides suitable nesting and foraging habitat for Allen’s hummingbird.

Although Allen’s hummingbird nesting is not tracked by CNDDB, it is a Bird of Conservation Concern listed by the USFWS (2017) as occurring in the project region. Based on the suitability of habitat and known nesting range, it is possible Allen’s hummingbirds utilize the BSA for nesting.

Potential Project‐Related Effects: Although nesting by Allen’s hummingbird has not been recorded within the BSA, suitable nesting sites are present. If active nesting is underway at the time of construction, direct or indirect impacts to breeding behavior or success could result. Such effects would be deemed a significant adverse impact pursuant to the statutes and guidelines of CEQA; impacts should be addressed in environmental review documents.

Impact avoidance measures are warranted, as outlined in Section 5.3, below. 519
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 24 California Thrasher
Regulatory Status: FESA: none; CESA: none; CDFW: none; USFWS: Bird of Conservation Concern; Global/State rarity ranking: none.

Description: The California thrasher (Toxostoma redivivum) is listed as a Species of Special Concern by CDFG (2017c) and it is protected under the MBTA and CFGC39. This relatively common resident of foothills and lowlands occupies moderate to dense chaparral habitat and, less commonly, extensive riparian thickets, especially with blackberry patches. It nests close to the ground and feeds on invertebrates, acorns, and forb seeds. California thrasher occurs across the length of California. Along the coastal fog belt north of San Francisco, it is restricted to drier sites.

Critical Habitat: The California thrasher is not listed under FESA; as such, Critical Habitat has not been designated for the species.

Habitat Suitability and Occurrence Data: No California thrashers were observed during the site reconnaissance. However, suitable nesting habitat is present within the proposed development area and vicinity. For this reason, the potential exists for the species to inhabit the project site.

Although California thrasher nesting is not tracked by CNDDB, it is a Bird of Conservation Concern listed by the USFWS (2017) as occurring in the project region. Based on the suitability of habitat and known nesting range, it is possible that the species occurs in the BSA and on the subject parcel.

Potential Project‐Related Effects: If present at the time of site clearing, project implementation could result in a take of the species, which would be in violation of the MBTA and would be deemed a significant adverse impact pursuant to the statutes and guidelines of CEQA; impacts should be addressed in environmental review documents. Impact avoidance measures are warranted, as outlined in Section 5.3, below. With the incorporation of these measures into the project design, impacts would be reduced to a less‐than‐significant level.

Oak Titmouse
Regulatory Status: FESA: none; CESA: none; CDFW: Special Animal (nesting); USFWS: Bird of Conservation Concern; Global/State rarity ranking: G4/S4.

Description: The oak titmouse (Baeolophus inornatus) is considered an oak obligate species, inhabiting oak woodlands, oak savannahs, piñon and juniper woodlands and occasionally suburban areas with oaks (Cicero, 2000; Baicich and Harrison, 2005). It is a year‐round resident throughout much of California. Nests are situated in natural or excavated cavities

39 CFGC § 3503
520
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 25 in trunks, primary and secondary branches, and stumps (Cicero, 2000). Breeding begins in March and is single‐brooded (Baicich and Harrison, 2005). The oak titmouse is a confirmed breeder in Santa Clara County (Bousman, 2007).

Critical Habitat: The oak titmouse is not listed under FESA; as such, Critical Habitat has not been designated for the species.

Habitat Suitability and Occurrence Data: Suitable habitat is present in the BSA, consisting of the coast live oak trees. Potential nest cavities were observed in oak trees during the site reconnaissance and an oak titmouse was observed foraging within the BSA.

Although oak titmouse nesting is not tracked by CNDDB, it is a Bird of Conservation Concern listed by the USFWS (2017) as occurring in the project region. Based on the suitability of habitat and known nesting range, it is possible that oak titmouse utilizes the BSA for nesting.

Potential Project‐Related Effects: Although nesting by oak titmouse was not confirmed within the BSA, suitable nesting sites are present. If active nesting is underway at the time of construction, direct or indirect impacts to breeding behavior or success could result. Such effects would be deemed a significant adverse impact pursuant to the statutes and guidelines of CEQA; impacts should be addressed in environmental review documents.

Impact avoidance measures are warranted, as outlined in Section 5.3, below.

San Francisco Dusky‐Footed Woodrat
Regulatory Status: FESA: none: CESA: none; CDFW: Species of Special Concern; Global/State rarity ranking: G5T2T3/S2S3.

Description: The San Francisco dusky‐footed woodrat (Neotoma fuscipes annectens; hereafter SFDW) is one of eleven recognized woodrat subspecies occurring in California (Matocq, 2002). It inhabits oak and riparian woodlands with a well‐developed understory and is distributed through the Santa Cruz Mountains and Diablo Range from the Pajaro River north to the San Francisco Bay (Hall, 1981). It is most common in riparian, oak woodland and scrub habitats, but is able to persist in semi‐rural areas in proximity to houses, if patches of native habitat are present. A study of a similar subspecies N. f. luciana on Camp Roberts found that densities increased significantly if dense under‐story was present; densities reached 46.7 animals per ha (18.9 per ac) in plots of dense vegetation (Tietje, 1995).

The SFDW is a medium‐sized native rodent with large ears and a long, scantily haired tail.

They build mounded stick nests that may range in size from 1‐2.5 m (3‐8 ft) across at the base and up to 1.8m (6 ft) tall. Less typically, they may den in tree cavities, rock crevices and ground holes that are well‐hidden and easily overlooked. Woodrats they tend to live in colonies of three to 15 nests or more. Nests may contain multiple chambers used for sleeping and food storage. Each nest is usually occupied by single adults or females with their litters 521
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 26 for a few months until the young disperse to nearby nests. Adult female woodrats live in the same nest until they die, when the nest is taken over by one of the female offspring. In this manner nests may be occupied and maintained by the same family for decades. They exhibit high site fidelity and build stick nests that may last for 20 years or more. They are also highly arboreal and sometimes construct aerial nests, utilizing evergreen or live oaks and other trees and shrubs with thick leaves (Kelly, 1990; Williams et al., 1992). Woodrat nests are also used by a wide variety of native amphibians, small mammals, reptiles and insects (Carraway and Verts, 1991).

Woodrats are generalist herbivores, consuming a variety of nuts, fruits, fungi, foliage and some forbs (Jameson and Peeters, 1988). They are mostly nocturnal in habit and active throughout the year. The SFDW breeds from February through September and may produce up to five litters per year, with litters containing one to four young (Zeiner, et al. 1988).

Critical Habitat: The SFDW is not listed under FESA; as such, Critical Habitat has not been designated for the species.

Habitat Suitability and Occurrence Data: No evidence of the presence of SFDW, such as stick nests, was detected on the subject parcel. However, due to the presence of abundant suitable habitat, the potential exists for this subspecies to move onto the site in the future.

The project site is located within the geographic range of SFDW. There are no records of SFDW from within 1.6 km (1 mi) of the project site, but there are two records from within

4.8 km (3 mi) (CNDDB, 2017). Despite the lack of nearby records, this wide‐ranging, relatively common subspecies is underreported in the CNDDB; it is highly likely that the species occurs in the vicinity of the project site.

Potential Project‐Related Effects: Although no woodrat nests were detected during the reconnaissance‐level survey, there is a potential for this species to move into and inhabit the subject parcel. Should SFDW move into the work area, construction‐related activities could result in direct mortalities of individuals and loss of nest structures. Such impacts would be considered a significant adverse effect pursuant to CEQA. Impact avoidance measures are warranted, as outlined in Section 5.3, below
Spotted Towhee
Regulatory Status: FESA: none; CESA: none; CDFW: none; USFWS: Bird of Conservation Concern; Global/State rarity ranking: none.

Description: The spotted towhee (Pipilo maculatus) is a large sparrow with a thick, pointed bill, short neck, chunky body, and long, rounded tail. They are found from the Great Plains to the Pacific Coast and from Canada to Mexico. In California, the species occurs from the Sierra Nevada to the coast.
522
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 27 Males have jet‐black upperparts and throat; their wings and back are spotted bright white.

The flanks are warm rufous and the belly is white. Females have the same pattern but are warm brown where males are black. In flight, look for white corners to the black tail.

Spotted towhees hop over the ground beneath dense tangles of shrubs, scratching in leaf litter for food, mainly insects, but also includes acorns, berries, and seeds. They also climb into lower branches to search for insects and fruits, or to deliver their quick, buzzy song.

The inhabit dry thickets, brushy tangles, forest edges, old fields, shrubby backyards, chaparral, coulees, and canyon bottoms, places with dense shrub cover and plenty of leaf litter. Spotted towhees place their nests on the ground or as high as 12 feet high deep inside thickets.

Critical Habitat: The spotted towhee is not listed under FESA; as such, Critical Habitat has not been designated for the species.

Habitat Suitability and Occurrence Data: No spotted towhees were observed during the site reconnaissance. However, suitable nesting habitat is present within the proposed development area and vicinity. For this reason, the potential exists for the species to inhabit the project site.

Although spotted towhee nesting is not tracked by CNDDB, it is a Bird of Conservation Concern listed by the USFWS (2017) as occurring in the project region. Based on the suitability of habitat and known nesting range, it is possible that the species occurs in the BSA and on the subject parcel.

Potential Project‐Related Effects: If present at the time of site clearing, project implementation could result in a take of the species, which would be in violation of the MBTA and would be deemed a significant adverse impact pursuant to the statutes and guidelines of CEQA; impacts should be addressed in environmental review documents. Impact avoidance measures are warranted, as outlined in Section 5.3, below. With the incorporation of these measures into the project design, impacts would be reduced to a less‐than‐significant level. 523

5.0 DISCUSSION
As described in Section 3.0, the project site is located in a residential area at the interface with undeveloped lands of San Juan Canyon. Although the subject parcel is undeveloped, it has been altered by historic grazing and grading. Habitats that would be impacted by the proposed home construction include ruderal, non‐native annual grassland and coast live oak woodland. While no special‐status plant or animal species are known to occur on site, there is a potential for impacts special‐status species. The implications of the proposed project as they relate to these resources are discussed below.

5.1 Special‐Status Natural Communities and Landscape Features As described in Section 4.1 above, project implementation would not result in significant adverse effects on special‐status natural communities or landscape features. No impact avoidance, minimization or mitigation measures are warranted.

5.2 Special‐Status Plant Species
As described in Section 4.2 above, project implementation would not result in significant adverse effects on special‐status plant species. No impact avoidance, minimization or mitigation measures are warranted.

5.3 Special‐Status Animal Species
As described in Section 4.3 above, a total of five special‐status animal species are considered to have a potential to occur on the subject parcel. These include Allen’s hummingbird, California thrasher, oak titmouse, San Francisco dusky‐footed woodrat, and spotted towhee, as well as numerous species of migratory birds.

Project implementation could therefore result in direct, indirect and/or cumulative impacts to special‐status animal species. Such impacts would be considered a significant pursuant to the statutes and guidelines of CEQA. A discussion of the implications and appropriate impact avoidance, minimization, or mitigation measures is presented below.

5.3.1 Implications of the Proposed Project: Special‐Status and Migratory Birds Within the project area, grasslands, shrubs, and trees provide nesting habitat for Allen’s hummingbird, California thrasher, oak titmouse, and spotted towhee, as well as many other migratory bird species. Site clearing activities (e.g., grubbing, grading, trenching, and tree removal or pruning) could result in direct or indirect impacts to nesting birds by causing the destruction or abandonment of occupied nests. To ensure compliance with the MBTA/MBTRA and the CFGC the measures outlined below should be performed.

1. Raptor Nests. Prior to the removal or significant pruning of any trees, they should be inspected by a qualified biologist for the presence of raptor nests. This is required 524
Wood Biological Consulting, Inc. – Biological Resource Assessment, Kraft Residence, Belmont 29 regardless of season. If a suspected raptor nest is discovered, the CDFW should be notified. Pursuant to the CFGC40, raptor nests, whether or not they are occupied, may not be removed until approval is granted by the CDFW.

2. Site Clearing – Non‐Breeding Season. If clearing, grubbing or tree removal/pruning are to be conducted outside of the breeding season (i.e., September 1 through January 31), no preconstruction surveys for nesting migratory birds are necessary.

3. Site Clearing – Breeding Season. If clearing and grubbing and tree removal or pruning are to be conducted during the breeding season (i.e., February 1 through August 31), a preconstruction nesting bird survey should be conducted. The survey should be performed by a qualified biologist no more than two weeks prior to the initiation of work. If no nesting or breeding activity is observed, work may proceed without restrictions. To the extent allowed by access, all active nests identified within 76 m (250 ft) for raptors and 15 m (50 ft) for passerines should be mapped.

4. Active Nesting. For any active nests found near the construction limits (76 m [250 ft] for raptors and 15 m [50 ft] for passerines) a qualified biologist should make a determination as to whether or not construction activities are likely to disrupt reproductive behavior. If it is determined that construction is unlikely to disrupt breeding behavior, construction may proceed. If it is determined that construction may disrupt breeding, a no‐construction buffer zone should be designated on the grading plans.   Avoidance of impacts on nesting migratory birds is the only acceptable mitigation; take of nesting birds is a violation of State and federal law. The ultimate size of the no‐construction buffer zone may be adjusted by a qualified biologist based on the species involved, topography, lines of site between the work area and the nest, physical barriers, and the ambient level of human activity. Site evaluations and buffer adjustments should be made in consultation with the CDFW and/or the USFWS Division of Migratory Bird Management, as appropriate.

If it is determined that construction activities are likely to disrupt raptor breeding, construction activities within the no‐construction buffer zone may not proceed until the qualified biologist determines that the nest is long longer occupied.

5. Nest Monitoring. If maintenance of a no‐construction buffer zone is not feasible, the Project Biologist should monitor the nest(s) to document breeding and rearing behavior of the adult birds. If it is determined that construction activities are likely to cause nest abandonment, work should cease immediately and the CDFW and/or the USFWS Division of Migratory Bird Management should be contacted for guidance.

With the incorporation of these measures, impacts to special‐status and other migratory bird species would be reduced to a less‐than‐significant level pursuant to the statutes and guidelines of CEQA.

5.3.2 Implications for Future Development: Impacts on San Francisco Dusky‐Footed Woodrat
Although no active nests of the SFDW were detected curing the present survey and no individual animals were observed, there is a high likelihood for SFDW to be encountered during construction due to the presence of abundant occupied habitat nearby. To avoid direct mortalities and adverse effects on SFDW, the following measures should be implemented.

1. Site Clearing. Prior to site clearing, grubbing or tree removal, the project biologist should survey for SFDW nests within and adjacent to the limits of grading. All nests (active or inactive) should be mapped and flagged in the field. If no stick nests are detected, no further surveys, monitoring or mitigation are warranted.

2. Nest Removal – Non‐Breeding Season. If a woodrat nest is detected in the work zone and it cannot be avoided, site clearing should be performed during the non‐breeding season (i.e., September 1 through November 30). During the non‐breeding season, the nest should be disassembled by hand and the nest materials (e.g., sticks) removed and disposed of off‐site. Any adult animals present should be permitted to disperse into adjacent habitat. This work may only be performed by a qualified biologist in coordination with the CDFW.

3. Nest Removal – Breeding Season. If site clearing must proceed during the breeding season (i.e., December 1 through August 31), it will be necessary to determine whether or not the nest is occupied. This may be done by direct observation over the course of at least two evenings no more than 48 hours prior to nest disassembly. Direct observation may consist of installation of camera traps at the nest or by a biologist on the ground. If no animals are observed, the nest may be disassembled by hand. If, during the process of disassembling the nest, live animals are encountered, nest materials should be replaced on top of the nest and the effort abandoned. Nest may not be disassembled if young woodrats are present. Construction must then be postponed until the end of the breeding season when juveniles are able to survive on their own.

With the incorporation of these measures, impacts to the SFDW would be reduced to less‐ than‐significant level pursuant to the statutes and guidelines of CEQA. 526

SUBJECT: Updated Biological Resource Assessment
Kraft Parcel, Monte Cresta Drive, Belmont
APN 043-165-180
This memorandum summarizes the results of a re-assessment of biological resources and potential biological constraints to the development of a parcel located at the western end of Monte Cresta Drive just west of the residence located at 2817 Monte Cresta Drive (Figures 1 and 2). The applicant proposes to construct a two-story residence on the 0.22-acre parcel (APN 043-165-180). Site plans for the home have been submitted separately.

This memorandum also updates, and where noted, revises the Biological Resources Assessment (BRA) prepared by Wood Biological Consulting in 20171 for the same project and parcel. That report was informed by previous biological resource studies that covered the project parcel and were prepared in support of the approved Monte Cresta Drive Road Improvement Project. These include a biological assessment and update (Wood Biological Consulting, 2004, 2012), an evaluation of habitats for the endangered mission blue butterfly (Wood Biological Consulting, 2009), and an Initial Study and Mitigated Negative Declaration (City of Belmont, 2011).

There have been only slight changes in the biological conditions on the project parcel (i.e., a few more shrubs establishing in grassland in the northwest corner), but no material change in the overall biological conditions of the site. Similarly, there have been some changes in the number of special-status species that appear in queries of biological databases (most of which have no potential to occur on the site), and some additional documented populations in the general vicinity, but these do not alter the conclusions about the potential for any of these species to occur, or the efficacy of provisional recommendations for actions to avoid or minimize the effects of the proposed project on these species.

The proposed project would not conflict with the goals and policies in the Conservation Element of City’s General Plan 2035, or with Land Use, Parks, recreation and Open Space, or Conservation elements of the General Plan EIR.

Updated Biological Resources Assessment (2022) 2
Kraft Parcel, Monte Cresta Drive, Belmont, CA
Methods
Wood Biological Consulting (WBC) conducted a reconnaissance survey of biological resources on and adjacent to the project parcel on May 23, 2022. During the survey, the entire parcel and accessible portions of vacant land to the west of the project parcel (part of the Biological Study Area described in the 2017 biological report) were traversed on foot, and observations were made of all plant and wildlife species and the types and extent of vegetation. Private properties within the study area were not accessed. A comparison was made between current conditions and descriptions and mapping of vegetation and habitat types during the previous biological studies of the site and vicinity. WBC also reviewed relevant documents in support of this re-evaluation of biological resources, including of the following.

The project parcel is located at the western terminus of Monte Cresta Drive just west of the residence located at 2817 Monte Cresta Drive (Figures 1 and 2). The 0.22-acre parcel descends steeply to the south.

Vegetation and wildlife habitats occurring within the project parcel consist of non-native annual grassland, coast live oak woodland, and anthropogenic habitat, and are similar in extent and species composition to what was described in the 2017 biological report (see Figure 3). Weed abatement, which was apparent during the May 2022 site visit, has been performed by the owner annually, as required by local ordinance, and has contributed to maintaining the vegetation in its current configuration.

There is some expansion of woody plants, such as coyote brush, into the annual grassland in the northwestern part of the parcel, which is also evident along the slope below the unpaved extension of Monte Cresta Drive. This is a typical progression of vegetation change in the region, but does not warrant re-classifying or re-mapping of the vegetation types.

Vegetation within the larger study area also remains fundamentally consistent with the 2017 descriptions and mapping, including additional areas of coast live oak woodland and non-native annual grassland, in addition to chamise chaparral and coyote brush scrub. No sensitive plant communities or 588

aquatic features (i.e., wetlands, streams or riparian habitat) occur within the project parcel or the larger study area.

Evidence of wildlife use on the project parcel also is similar to what was described in the 2017 biological report, including observations or signs of use by mule deer, corvids (e.g., American crow), raptors (e.g., red-tail hawk), and song birds. Animal movement corridors on and adjacent to the project parcel remain unchanged from the 2017 biological report account. The parcel is at the periphery of larger interconnected and protected open space areas. Development of the parcel would not have a significant adverse effect on wildlife movement in the local area or region.

Special-Status Plants
To update the 2017 biological report information on special-status plant species, new queries were made of three standard databases that track occurrences of plants, and animals and natural communities that are listed or proposed for listing under the Federal Endangered Species Act; listed or candidates for listing as endangered or threatened under the California Endangered Species Act; have a State rarity ranking of S1, S2, or S3 indicating they are critically imperiled; listed as rare under the California Native plant Protection Act; meet the definition of endangered, threatened or rare under the CEQA Section 15380; locally significant species for which sufficient information exists to warrant consideration under CEQA.

The CNDDB, USFWS IPaC, and California Native Plant Society Rare Plant Inventory were queried using the same search criteria as in the 2017 biological report. Results of these searches were compared to determine if additional species should be included in the current evaluation of the proposed project, either because they are now included in the database search results, or because new information on the location of populations in the vicinity of the project parcel.

A nine-quad search2 of the California Natural Database (CNDDB) resulted in four additional species (73, vs. 69 in 2017). Of these, one is an aquatic plant, Sanford’s arrowhead (Sagittaria sanfordii), with no potential to occur on the project parcel. Long styled sand spurrey (Spergularia macrotheca var. longistyla) occurs in wetlands or on the margins of seasonally wet areas. No such habitat exists near the project parcel, therefore it is presumed absent.

Four species are summarized below: two species did not appear in the 2017 CNDDB query, but are in the 2022 updated query. Two other species were identified in the 2017 query, but not within three miles of the project parcel (this distance was used as a search criterion in the 2017 biological report). They have since been identified as occurring or having the potential to occur within three miles of the project parcel.
• Island rock lichen (Hypogymnia schizidiata), for which there are few known occurrences, and little is known about its habitat and range. Most populations occur on or near oldgrowth stands of coast scrub, which is absent from the project parcel and biological study area. Therefore, the likelihood of this species occurring on the site is low. 2 The standard nine-quad search centered on the San Mateo USGS 7.5-minute quadrangle, and also included the Half Moon Bay, Hunters Point, Montara Mountain, Palo Alto, Redwood Point, San Francisco South, San Leandro, and Woodside quads.

• Scouler’s catchfly (Silene scouleri ssp. scouleri) is a perennial herbaceous plant that occurs in coastal bluff scrub, coastal prairie and grasslands. There are about a dozen occurrences around Montara Mountain, San Pedro Mountain, and San Bruno Mountain, but none in the immediate vicinity of Belmont or within three miles of the project parcel. The May 2022 biological survey occurred slightly before the peak flowering season of this species (June-August), but the perennial species would have been detectable. None were observed, nor were any other species in the genus Silene. Therefore, the likelihood of this species occurring on the site is low.
• Choris’ popcorn flower (Plagiobothrys chorisianus var. chorisianus) was documented in 20153 within three miles of the project parcel. The population is west of Crystal Springs reservoir in mesic coastal prairie/grassland, in association with several wetland plant species. No such habitat exists on the project parcel or within the larger in the biological study area, and no plants in the genus Plagiobothrys were observed during the May 2022 survey, which occurred during the flowering time of this species. Therefore, this species is presumed absent from the project parcel.
• Hillsborough chocolate lily (Fritillaria biflora ssp. ineziana) was recently documented in the general vicinity of the project parcel, and may occur within one mile. However, because the species is attractive to horticultural poaching, the exact locations are suppressed. The species has a high affinity for serpentine grasslands (growing on soil derived from the serpentinite rock), which does not occur at on the project parcel or in the larger biological study area, therefore, this species is presumed absent from the site.

In addition to the species summarized above, 10 additional species were added to the California Rare Plant Society Rare Plant Inventory for the nine-quad query. Of these, suitable or marginally suitable habitat exists on the project parcel and in the larger study area for four of these species:
pink star-tulip (Calochortus uniflorus), bristly leptosiphon (Leptosiphon acicularis), spring lessingia (Lessingia tenuis), and Michael’s rein orchid (Piperia michaelii). The May 2022 occurred during the flowering period of these species, but none were observed. Additionally, each of these four species has a State Rarity Rank of S3 or S4, and a California Rare Plant Rank (CRPR) of 4.2 or 4.3, indicating plants of limited distribution in California and not imperiled, and are not eligible for listing as endangered or threated. These species often do not warrant consideration under CEQA.

No suitable habitat, such as wetlands, sandy or serpentine soils, or conifer forests exist on the project parcel or in the larger biological study areas. Therefore, the following species are considered to have no potential to occur on the site: bristly sedge (Carex comosa), harlequin lotus (Hosackia gracilis), large-flowered leptosiphon (Leptosiphon grandiflorus), broad-lobed leptosiphon (Leptosiphon latisectus), and Hickman's popcorn flower (Plagiobothrys chorisianus var. hickmanii). These species also are ranked S3 or S4, and CRPR 4.

Recent observations of some special-status plants that were evaluated in the 2017 report have recently been documented in the vicinity of the project parcel (CNDDB; Belmont General Plan EIR). 3 Although the 2015 record predates the 2017 biological report, it may take a year or more before the record appears in the CNDDB.

San Francisco collinsia (Collinsia multicolor) and Franciscan onion (Allium peninsulare var. franciscana) have been documented in Laurelwood Park and Sugarloaf Open Space to the northwest of the Project parcel, and in Waterdog Lake and Open Space to the south (Figure 4). However, these new occurrences do not change the conclusions of the 2017 report for these species. No additional surveys or mitigation for special-status plants is warranted.

A search of the U.S. Fish and Wildlife Service’s Information for Planning and Consultation (IPaC) database resulted in the same set of five federally listed plant species that were evaluated in the 2017 biological report. Consistent with the 2017 biological report, four of these species were found to have no potential to occur on the project parcel or in the biological study area due to lack of suitable habitat or serpentine soil. Marginally suitable habitat for one species, San Mateo woolly sunflower (Eriophyllum latilobum) still persists on the site, but this showy perennial flowering shrub would have been detected during the May 2022 survey.

The 2017 biological report concluded that the potential for occurrence of all special-status plant species can be ruled out due to a lack of suitable habitat, lack of suitable soils, geographic location of the BSA relative to known occurrences, or that the fact that they would have been detectable during the previous survey and the May 2022 survey. Project implementation would not result in significant adverse effects to special-status plant species. No additional surveys or impact avoidance, minimization or mitigation measures are warranted. Based on this re-evaluation, this conclusion remains unchanged.

Special-Status Animal Species
A review of standard databases for special status wildlife resulted in some changes to the list of species with potential to occur on the project parcel and the larger biological study area. A ninequad search of the California Natural Database (CNDDB) resulted in six additional species (71 vs. 65 in 2017). Of these, five are obligate aquatic species with no potential to occur in the study area:

Stellar’s sea lion (Eumatopias jubatus), western ridged snail (Gonidea angulata), California linderiella (Linderiella californica), Pacific walker (Pomatiopsis californica), and foothill yellow-legged frog (Rana boylii). The sixth species, Pheres blue butterfly (Icaria Icaria pheres) is considered extinct.

A search of the U.S. Fish and Wildlife Service’s Information for Planning and Consultation (IPaC) database resulted in the same set of federally listed animal species that were evaluated in the 2017 biological report. The 2022 IpaC query result did differ from the 2017 result with respect to birds protected by the Migratory Bird Treaty Act. Thirteen birds included on the 2017 list did not appear on the 2022 list, while seven new species were included in the 2022 query result. Of these seven, Clark’s grebe (Aechmophorus clarkii) and willet (Catoptrophorus semipalmatus) are aquatic or shorebirds and therefore have no potential to occur at the project site. Two raptor species, bald eagle (Haliaeetus leucocephalus ) and golden eagle (Aquila chysaetos), could transit the area, but would not use the site for nesting, and are presumed absent from the site. • Long-eared owl (Asio otus) nests in conifer, oak, riparian, pinyon-juniper, and desert woodlands that are either open or are adjacent to grasslands, meadows, or shrublands for hunting prey. They are uncommon in San Mateo County, and may not currently 591

Updated Biological Resources Assessment (2022) 6
Kraft Parcel, Monte Cresta Drive, Belmont, CA
breed in the County4. Based on the moderately suitable habitat in the biological study area, long-eared owls could be present, although the likelihood is low. No sign of owls (nests or pellets) was observed during the May 2022 survey, or earlier surveys. • Olive-sided flycatcher (Contopus cooperi) nests in mixed conifer, montane hardwoodconifer, coast redwood, Douglas-fir, lodgepole pine, red fir (Grinnell and Miller, 1944; Garrett and Dunn, 1981). In the San Francisco Bay Area, it is considered a summer resident occurring in small numbers restricted to heavily forested areas of cypress, eucalyptus, pine, redwood, or spruce (Grinnell and Wythe, 1927). Suitable nesting habitat is not present on the project parcel or in the larger biological study area, therefore this species has a low likelihood of occurring at the site.
• Wrentit (Chamaea fasciata) nests in a variety of vegetation types with dense shrub understory, such as coastal scrub, coyote brush scrub, chaparral, riparian, oak and confer forests, poison oak or blackberry thickets, and parks and gardens. Many observations have been made in San Mateo County open spaces, including Laurelwood Park, Waterdog Lakes, Pulgas Ridge and Emerald Hills. Therefore, suitable habitat is present on and adjacent to the project parcel, and its potential to occur cannot be ruled out.

Nesting Birds
As described in the 2017 biological report, special-status birds, raptors and most migratory bird species in California also are protected by the MBTA and by the California Fish and Game Code §3503 (nesting birds) and §3503.5 nesting raptors). The recommended measures included in the 2017 biological report (Section 5.3.1, addressing special-status and migratory birds) would reduce potential project-related effects to nesting birds a less than significant level. As written, Section 5.3.1 would also adequately address the additional species summarized above. The measures are consistent with California Department of Fish and Wildlife requirements for preconstruction surveys by a qualified biologist, timing of the survey relative to start of construction activities, seasonal limitations, and agency notification and consultation requirements in the event that nesting birds are detected in the project area.

Alternatively, the standard conditions of approval in the City of Belmont Design Review Application Checklist5 may be applied to address nesting birds. The language below is similar to Section 5.3.1 of the 2017 biological report, albeit in a more condensed form. Inclusion of the City’s language as a condition of approval would meet the intent of the recommendations in Section 5.3.1, as well as CDFW requirements.

2) Buffer Zone: If it is not possible to schedule construction between February and August, then pre-construction surveys for nesting raptors will be conducted by a qualified biologist or ornithologist in order to ensure that no raptor nests will be disturbed during project implementation. This survey will be conducted no more than 15 days prior to the initiation of construction activities during the early part of the breeding season (February through April) and no more than 30 days prior to the initiation of these activities during the late part of the breeding season (May through August). During this survey, the biologist will inspect all trees in and immediately adjacent to the impact areas for raptor nests. If an active raptor nest is found close enough to the construction area to be disturbed by these activities, the ornithologist, in consultation with CDFG6 , will determine the extent of a construction-free buffer zone to be established around the nest.

San Francisco Dusky-Footed Woodrat (Neotoma fuscipes annectens) The project parcel contains no stick nests of San Francisco dusky footed woodrat (SDFW) and is only marginally suitable due to annual weed abatement activity, which prevents an accumulation of woody debris on the ground. During the May 2022 survey, one SDFW nest was identified approximately 160 ft northwest of the project site in dense scrub vegetation alongside the Monte Cresta trail (Figure 5). Other occurrences have been documented along the north end of the trail (WBC, pers. obsv.). As noted in the 2017 biological study and the City of Belmont General Plan and EIR, the project site is located within the geographic range of SFDW. Although there are no records of SFDW from within one mile of the project site, and only two records from within three miles (CNDDB, 2022), this wide-ranging subspecies is underreported in the CNDDB, but locally common in the open space areas of San Mateo County.

The 2017 biological report concluded that although no SDFW nests were detected during the reconnaissance-level survey, there is a potential for this species to move into and inhabit the subject parcel. Based on this re-evaluation, this conclusion remains unchanged. If SFDW move into the work area, construction-related activities could result in direct mortalities of individuals and loss of nests.

In the event that SDFW are detected before construction of the proposed project, implementation of the recommended measures included in the 2017 biological report (Section 5.3.2) would reduce potential project-related effects to a less than significant level. 6 CDFG refers to California Department of Fish and Game; as of January 2013, the department name changed to California Department of Fish and Wildlife (CDFW).

IPaC resource list
This report is an automatically generated list of species and other resources such as critical habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's (USFWS) jurisdiction that are known or expected to be on or near the project area referenced below. The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly affected by activities in the project area. However, determining the likelihood and extent of effects a project may have on trust resources typically requires gathering additional site-specific (e.g., vegetation/species surveys) and project-specific (e.g., magnitude and timing of proposed activities) information.

Below is a summary of the project information you provided and contact information for the USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional information applicable to the trust resources addressed in that section.

Endangered species
This resource list is for informational purposes only and does not constitute an analysis of project level impacts.

The primary information used to generate this list is the known or expected range of each species. Additional areas of influence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential effects to species, additional site-specific and project-specific information is often required.

Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local office and a species list which fulfills this requirement can only be obtained by requesting an official species list from either the Regulatory Review section in IPaC (see directions below) or from the local field office directly.

For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an official species list by doing the following:

1. Draw the project location and click CONTINUE.

2. Click DEFINE PROJECT.

3. Log in (if directed to do so).

4. Provide a name and description for your project.

5. Click REQUEST SPECIES LIST.

Listed species and their critical habitats are managed by the Ecological Services Program of the U.S. Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic and Atmospheric Administration (NOAA Fisheries ).

Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown on this list. Please contact NOAA Fisheries for species under their jurisdiction.

1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also shows species that are candidates, or proposed, for listing. See the listing status page for more information. IPaC only shows species that are regulated by USFWS (see FAQ).

2. NOAA Fisheries, also known as the National Marine Fisheries Service (NMFS), is an office of the National Oceanic and Atmospheric Administration within the Department of Commerce.

probability of presence breeding season survey effort no data Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high.

How is the probability of presence score calculated? The calculation is done in three steps:

1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.

2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is

0.05/0.25 = 0.2.

3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score.

To see a bar's probability of presence score, simply hover your mouse cursor over the bar.

Breeding Season ( )
Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area.

Survey Effort ( )
Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys.

To see a bar's survey effort range, simply hover your mouse cursor over the bar.

No Data ( )
A week is marked as having no data if there were no survey events for that week.

Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round.

Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure.

To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site.

What does IPaC use to generate the migratory birds potentially occurring in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location.

The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development.

Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool.

What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN).

This data is derived from a growing collection of survey, banding, and citizen science datasets . 618
Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link.

How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area.

What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:

1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands);

2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and

3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing).

Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.

Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage.

Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring.

What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur.

Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable.

In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

Coastal Barrier Resources System
Projects within the John H. Chafee Coastal Barrier Resources System (CBRS) may be subject to the restrictions on federal expenditures and financial assistance and the consultation requirements of the Coastal Barrier Resources Act (CBRA) (16 U.S.C. 3501 et seq.). For more information, please contact the local Ecological Services Field Office or visit the CBRA Consultations 619
website. The CBRA website provides tools such as a flow chart to help determine whether consultation is required and a template to facilitate the consultation process.

THERE ARE NO KNOWN COASTAL BARRIERS AT THIS LOCATION.

Data limitations
The CBRS boundaries used in IPaC are representations of the controlling boundaries, which are depicted on the official CBRS maps. The boundaries depicted in this layer are not to be considered authoritative for in/out determinations close to a CBRS boundary (i.e., within the "CBRS Buffer Zone" that appears as a hatched area on either side of the boundary). For projects that are very close to a CBRS boundary but do not clearly intersect a unit, you may contact the Service for an official determination by following the instructions here:
https://www.fws.gov/service/coastal-barrier-resources-system-property-documentation Data exclusions
CBRS units extend seaward out to either the 20- or 30-foot bathymetric contour (depending on the location of the unit). The true seaward extent of the units is not shown in the CBRS data, therefore projects in the offshore areas of units (e.g., dredging, breakwaters, offshore wind energy or oil and gas projects) may be subject to CBRA even if they do not intersect the CBRS data. For additional information, please contact [email protected].

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

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

THERE ARE NO KNOWN WETLANDS AT THIS LOCATION.

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

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

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

Data exclusions
620
Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery.

Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities. 621

Site:0 Monte Cresta, Belmont, CA
Dear Mr. Kraft,
As requested I have reviewed the revised plans dated 5/29/2018. The new plan results in the removal of tree #1 a 24” Coast Live Oak. This tree is the worst tree on the site SEE PHOTO BELOW. Coast live oak tree #1 is codominant at 4 feet with the presence of included bark. The weak crotch formation would have been prone to failure because as the 2 leaders grow they will continue to push against each other often to the point of failure. This tree is the best tree to remove due to its poor structure.

The balance of the trees remain but the site requires some retaining walls to meet height restrictions. Building these walls close to the existing trees is not a positive addition for the trees however because these trees are very young and only a small portion of the root system will be disturbed they should be able to tolerate this intrusion and thrive.

The following is a recap of the previous report:

Method:

All inspections were made from the ground; the trees were not climbed for this inspection. The trees in question were located on a map provided by you. The trees were then measured for diameter at 54 inches above ground level (DBH or diameter at breast height). The trees were given a condition rating for form and vitality. The trees condition rating is based on 50 percent vitality and 50 percent form, using the following scale. 1 - 29 Very Poor
30 - 49 Poor
50 - 69 Fair
70 - 89 Good
90 - 100 Excellent
The height of the trees was measured using a Nikon Forestry 550 Hypsometer. The spread was paced off. Comments and recommendations for future maintenance are provided. 629

*Indicates tree on neighbors property
Summary:

The trees on site are all native coast live oak trees.

The site is in an untouched area where there is no
existing home, in the hills of Belmont. All of the trees are located on a slope, near the bottom of the hill
where the rear of the home is proposed. All of the
trees surveyed are in fair condition except for coast
live oak tree #3 that is severely suppressed and is
growing at a 45 degree angle. This tree is far away
from any proposed work and will not be affected by
construction. During my investigation I found that the
majority of the trees on site had buried root crowns.

As a part of normal maintenance these roots crowns
should be exposed in order to discourage root rot.

This will need to be done every 2-4 years as debris
Showing location of trees will naturally build up on the trunks of the trees as a result of being located on a slope.

Coast live oak tree #1 is codominant at 4 feet with the presence of included bark. This weak crotch formation is prone to failure because as the 2 leaders grow they will continue to push against each other often to the point of failure. A cable can be installed as a mitigation measure at a height of 2/3 the height of the tree, this will reduce the chance of a leader failure. Also the proposed light trimming of this tree will also reduce the chance of a leader failure.

Showing included bark on tree #1
The rear of the home, near the trees on site, is to be supported by piers and structural steel that is above grade. This type of foundations will significantly lower the impact to the retained trees on site as this type of foundation eliminates the need to cut into the root zone of the trees. Coast live oak #1 is the closest tree on site to the proposed work. The tree is 14 feet away from the proposed piers. Light trimming of this tree will need to take place in order to drill the piers.

Trimming to remove the deadwood in the tree should also take place at this time. Following ANSI standards, trimming shall not exceed 25% of the total foliage of the tree. Impacts to this tree are expected to be minor. During drilling near this tree the site arborist shall be onsite to inspect, document and offer mitigation measures. The remaining trees are a good distance away from the proposed work and are expected to have no impacts from construction activities. The following tree protection plan will help ensure the safety and health of the retained trees on site.

Trees that are under the protected size (10 inches in diameter) but are still to be retained should be protected in the same manner. At this site fencing will run along the back perimeter of the property and protect all of the trees. The fencing shall be placed at the farthest distance possible while still letting construction activities occur in a safe manner.

Tree Protection Plan:

Tree Protection Zones
Tree protection zones should be installed and maintained throughout the entire length of the project. Fencing for tree protection zones should be 6’ tall, metal chain link material supported by metal 2” diameter poles, pounded into the ground to a depth of no less than 2’. The location for the protective fencing should be as close to the dripline of desired trees as possible, still allowing room for construction to safely continue. No equipment or materials shall be stored or cleaned inside the protection zones. Areas outside protection zones, but still beneath the tree’s driplines, where foot traffic is expected to be heavy, should be mulched with 4-6” of chipper chips. The spreading of chips will help to reduce compaction and improve soil structure. Tree protection fencing shall be up before the start of the project.

0 Monte Cresta 1/6/16 (4)
Root Cutting and Grading
Any roots to be cut shall be monitored and documented. Large roots (over 2” diameter) or large masses of roots to be cut must be inspected by the site arborist. The site arborist, at this time, may recommend irrigation or fertilization of the root zone. All roots needing to be cut should be cut clean with a saw or lopper. Roots to be left exposed for a period of time should be covered with layers of burlap and kept moist.

Trenching and Excavation
Trenching for irrigation, drainage, electrical or any other reason shall be done by hand when inside the dripline of a protected tree. Hand digging and the careful placement of pipes below or besides protected roots will significantly reduce root loss, thus reducing trauma to the tree. All trenches shall be backfilled with native materials and compacted to near its original level, as soon as possible. Trenches to be left open for a period of time, will require the covering of all exposed roots with burlap and be kept moist. The trenches will also need to be covered with plywood to help protect the exposed roots.

Irrigation
The coast live oak trees on the property will not need any irrigation as they are in there native range. Irrigation for the coast live oak trees will only be needed if their root zones are impacted.

At the time of drilling the piers the site arborist shall set up a irrigation plan as part of the mitigation measures if needed although not likely.

The information included in this report is believed to be true and based on sound arboricultural principles and practices.

Sincerely,
Kevin R. Kielty David P. Beckham

RE: Planning Application No. 2015-0057: Certificate of Compliance Application for APN 043- 165-180; 043-242-210; 043-041-030
Dear Applicant:

This letter is a follow-up to your April 7, 2021 response regarding the Planning Application for a Certificate of Compliance ("COC") for APN 043-165-180; 043-242-210; and 043-041-030. By way of background, the City's September 25, 2020 COC evaluation and property title analysis for the . three (3) subject lots yielded the following assessment:
• Lot 55, block 113 (APN 043-165-180) is the product of an illegal parent parcel created without a map. Lot 55 is therefore not eligible for a certificate of compliance but should be issued a conditional certification of compliance.
• Lot 19, block 114 (APN 043-242-210) is the product of an illegal parent parcel created without a map. Lot 19 is therefore not eligible for a certificate of compliance but should be issued a conditional certification of compliance.
• Lot 3, block 122 (APN 043-041-030) was legally created by conveyance at a time when neither the SMA nor the City of Belmont required a map to divide property, and therefore is entitled to a certificate of compliance.

The City carefully reviewed the April 7, 2021 letter from your attorney, the focus of which was the legality of Lot 55, block 113. The letter's arguments that lot 55 was created by the 1927 Map appears to go against the weight of the controlling court decisions including decisions referenced in the letter. The argument that lot 55 was created by deed conveyance with other contiguous lots shown on the 1927 Map before 1945 does not provide citation to case law or analysis of the actual conveyance language or description of the property conveyed in the deeds to support that assertion.

The letter also argues that lot 55 should be entitled to a certificate of compliance under Government Code Section 66499.35(c) because the City issued a permit (TE2015-0200} to 633
