SUBJECT: Biological Resources Assessment for the 841 Patricia Drive Project (ARCH0040-2021; APN 052-520-063), City of San Luis Obispo, CA David Wolff Environmental (DWE) is pleased to submit this Biological Resources Assessment (BRA) for the 841 Patricia Drive residential development project (proposed project) in the City of San Luis Obispo, CA (APN 052-520-063; ARCH-0040-2021). This BRA has been prepared to establish existing conditions of the proposed project site based on field surveys and the review of project plans provided by the project team.

1.0 INTRODUCTION AND PURPOSE
The proposed project on an infill parcel flag lot includes construction of a residence, accessory dwelling unit, storage shed, and a span bridge creek crossing to connect the two buildable areas of the 1.41-acre property. The property is accessed from a gravel driveway off of Patricia Drive. DWE Principal Ecologist David Wolff reviewed available background data and conducted biological resources field surveys of the proposed project site. The purpose of this biological resources assessment is to document existing conditions of the proposed project site and to evaluate the potential for any direct or indirect significant impacts on biological, wetland or riparian resources, or adverse effects on any rare, threatened, or endangered plant or wildlife species (special-status species).

2.0 PROJECT DESCRIPTION
The proposed project includes construction of a new 4,900 square foot single family residence on 0.36-acre allowable building area, a new 825 square foot accessory dwelling unit (ADU) on 0.09-acre allowable building area, and a 128 square foot detached accessory building (storage shed) on an undeveloped flag lot within an infill parcel of an existing subdivision near the western edge of the City of San Luis Obispo (City). The site is bisected by a drainageway (creek) and riparian corridor with required setbacks (0.78 acre) that separates the two allowable buildable areas of the property. See attached Figures 1 and 2. An ATTACHMENT 3

David Wolff Environmental, LLC 841 PATRICIA DRIVE RESIDENTIAL PROJECT BIOLOGICAL RESOURCES ASSESSMENT |2
Biological & Wetland Resources Assessments – Regulatory Compliance Specialist approximately 55-foot long by 12-foot-wide span vehicle bridge is proposed for access to the ADU and storage shed from the primary residence driveway and Patricia Drive. The applicant proposes to plant ten 5 to 15-gallon coast live oak trees within the riparian corridor setback to enhance the habitat and provide replacement for the minor tree removal and pruning required to place the span bridge.

3.0 METHODS
DWE conducted a review of available background information including aerial photography of the project area (Google Earth), the Natural Resources Conservation Service soil survey, and the results of the California Natural Diversity Data Base (CNDDB) for the San Luis Obispo USGS quadrangle map. The CNDDB provided a list of special-status plant and wildlife species, and natural communities of special concern that have been recorded in the region of the project site. The CNDDB records help to focus the field survey efforts and evaluation of potential project effects on specific species or habitats. It is noted that the CNDDB does not necessarily include all special-status species potentially occurring onsite or in the region, but rather only those that have been recorded by the CNDDB.

DWE Principal ecologist David Wolff conducted biological resources reconnaissance and floristic inventory and rare plant survey on April 22, 2021 at a time of peak expression of the onsite botanical resources. Surveys were conducted by walking the entirety of the proposed project site recording plant and wildlife species observed and general site characteristics and those of the immediate surrounding area. Conditions for the site survey were conducive to the purpose of documenting plant and wildlife habitat to establish existing conditions. The purpose of the field surveys was to document existing conditions in terms of habitat for plant and wildlife species, presence/absence for special-status plant species, suitability of habitat for special-status wildlife, and the potential to support wetland and/or riparian habitats and/or waters of the U.S./State. The field surveys were conducted to include a complete floristic inventory and rare plant survey as they were conducted during the peak 2021 growing season and full expression of the onsite flora. The study area habitat types were described by the aggregation of plants and wildlife based on the composition and structure of the dominant vegetation observed at the time the field reconnaissance was conducted.

DWE Principal Ecologist David Wolff reviewed the available background information and available aerial photography, conducted the field surveys, and is the primary author and principal in charge of report preparation. The survey data collected on plant and wildlife species and conclusions presented in this biological and wetland assessment are based on the methods and field reconnaissance conducted over the project site as described above.

4.0 EXISTING CONDITIONS AND REGULATORY SETTING
This section established the existing conditions of the proposed project site and regulatory setting for the residential development project. Plant communities are described by the assemblages of plant species that occur together in the same area forming habitat types.

Community alliance used in this report follow A manual of California vegetation, 2nd edition (Sawyer et al. 2009). Plant names used in this report follow the 2012 Jepson Manual, Vascular Plants of California, Second Edition Thoroughly Revised and Expanded.

The USDA Natural Resources Conservation Service (NRCS; Soil Conservation Service, 1977) has identified one soil series mapping unit within the project site, Cropley clay, 2 to 9 percent slopes (128). This is a very deep moderately well drained, soil with slow permeability, occurring on alluvial fans and plains formed in alluvium weathered from sedimentary rocks. Typical surface layer is dark gray, very dark gray and light brownish gray clay about 36 inches thick. The underlying material is brown silty clay loam to a depth of 60 inches or more. The west side of the property (proposed primary residence area) appeared to be compacted fill leading to the slope down to the creek. Deep surface cracks were observed on the east side of the creek that appeared more typical of the Cropley clay soil surface characteristics.

4.1 BIOLOGICAL RESOURCES EXISTING CONDITIONS
The proposed project site supports two plant communities, disturbed non-native annual grassland on each side of the arroyo willow riparian habitat along the drainage that bisects the site. Attached Figure 3 provides a project area habitat map showing the location and extent of the habitat on the proposed project site. Figure 4 includes a set of onsite representative photographs. A complete list of plant species observed during the floristic inventory and rare plant survey is attached as Table 1.

BOTANICAL RESOURCES
The east and west sides of the proposed project site are composed of disturbed non-native annual grassland habitat, or semi-natural annual brome grassland alliance (CDFW CA Code:

42.026.00), that is typically dominated by non-native annual grasses and herbaceous broadleaf plant species, along with a few native forbs and wildflowers. The non-native annual grassland on the compacted level area of the western side was observed to be relatively low in species diversity and dominated by non-native oats (Avena sp.), filarees (Erodium botrys, E. cicutarium), ripgut brome (Bromus diandrus), smooth cat’s ear (Hypochaeris glabra), and abundant scattering of non-native treasureflower (Gazania sp.) groundcover. The slope down to the riparian area had a dense cover of field mustard (Brassica rapa) and crete weed (Hedypnois cretica). Integrated as a component of the nonnative dominated grassland on the west were a few purple needlegrass (Stipa pulchra) along with very few San Luis Obispo (Cambria) morning glory (Calystegia subacaulis ssp. episcopalis). The grassland habitat on the west side of the riparian corridor totals 0.57 acre.

ATTACHMENT 3

Page 781 of 1373 ends

David Wolff Environmental, LLC 841 PATRICIA DRIVE RESIDENTIAL PROJECT BIOLOGICAL RESOURCES ASSESSMENT |4
Biological & Wetland Resources Assessments – Regulatory Compliance Specialist The eastern project area grassland (0.31 acre) was similar in composition to the west side dominated by a dense cover of oats and landscape escaped treasureflower, but without the stand of field mustard and crete weed. The eastern grassland flat had more abundant purple needlegrass that is integrated into the non-native grassland habitat along with more San Luis Obispo morning glory. From a habitat perspective it still constitutes a non-native annual grassland and not a purple needlegrass grassland habitat.

The drainage (creek) riparian corridor (0.53 acre) bisecting the site supports arroyo willow thicket habitat, Salix lasiolepis Woodland Alliance (CDFW: 61.201.00, CNDDB CTT63200CA). This alliance is dominated by arroyo willow (Salix lasiolepis), which is characterized as a tall shrub or tree-like growth habit that may reach up to eight meters in height. Large and small coast live oak (Quercus agrifolia) trees occur throughout the corridor, along with a big leaf maple (Acer macrophyllum), and planted sycamore (Platanus racemosa). There is little native understory vegetation limited to scattered landscape escapes.

The City has depicted the creek riparian corridor as a wildlife corridor in the Conservation and Open Space Element (COSE) with supporting policies in the Land Use Element and COSE for the protection and enhancement of creeks and wildlife habitat and corridors. The creek emanates from a large culvert and small culvert under Patricia Drive from Bishop Peak runoff and likely stormwater runoff from the residential neighborhood. The small culvert from the north end of the site is an open swale with creeping spikerush (Eleocharis macrostachya), curly dock (Rumex crispus), and iris-leaved rush (Juncus xiphiodes) leading to the main drainageway from the large culvert under the woody riparian vegetation. The creek bottom has narrow braided low flow channels along the flow path with likely unconsolidated sheet flow across the drainage bottom during heavy rain events. The open channel and riparian corridor continue offsite downstream to the backyards of houses along Westmont Avenue where it appears to go underground through the residential development.

WILDLIFE RESOURCES
The project site is a remnant isolated patch of grassland and riparian habitat within the residential urbanized landscape at the outer edge of the City at the base of Bishop Peak. The site can provide habitat for a variety of wildlife species that have become adapted to the urban environment such as raccoons, opossums, skunks, with evidence of deer, gopher, and ground squirrels observed. Even in urbanized areas, riparian corridors and trees can provide habitat for a variety of wildlife species that have become adapted to the urban environment, but in particular to resident and migratory birds. Common birds observed during DWE field survey included the northern mockingbird, house finch, Anna’s hummingbird, California towhee, California quail, Wilson’s warbler, Hutton’s vireo, and black-headed grossbeak.

Given the small infill site is surrounded by urban development, other wildlife use is likely ATTACHMENT 3

Biological & Wetland Resources Assessments – Regulatory Compliance Specialist limited with generally low wildlife values. While depicted by the City as a wildlife corridor, the project site does not represent any specific migratory or movement corridor for wildlife amongst the dense surrounding residential development as the riparian corridor ends abruptly near Westmont Avenue.

4.2 SPECIAL-STATUS SPECIES
Special-status species are those plants and animals listed, proposed for listing, or candidates for listing as threatened or endangered by the United States Fish and Wildlife Service (USFWS) or the National Marine Fisheries Service (NMFS) under the federal Endangered Species Act (FESA); those listed or proposed for listing as rare, threatened, or endangered by the CDFW under the California Endangered Species Act (CESA); animals designated as “Species of Special Concern” by the CDFW; and plants occurring on lists 1B, 2, and 4 of the CNPS Inventory of Rare and Endangered Vascular Plants of California. Natural Communities of Special Concern are habitat types considered rare and worthy of tracking in the California Natural Diversity Database (CNDDB) by the CNPS and CDFW because of their limited distribution or historic loss over time.

The search and review of the CNDDB revealed 58 historic and extant (presumed existing) occurrences of special-status plant and wildlife species, and two natural communities of special concern within the San Luis Obispo USGS quadrangle map with potential to occur on the project site. This quadrangle map CNDDB search was used because of the urbanized landscape surrounding the proposed project site. Attached Table 2 is a list of the CNDDB special-status plant and wildlife species with recorded occurrences used for project evaluation. The following briefly describes or summarizes the special-status species issues and observations or potential for occurrence on the project site.

Special-Status Botanical Resources
The CNDDB search revealed the recorded occurrences of 34 special-status plant species and two natural communities of special concern with the potential to occur on the project site.

No natural communities of special concern occur on the project site. Purple needlegrass dominated grasslands can be considered a valley needlegrass grassland natural community of special concern, however, the onsite occurrence of purple needlegrass is only a component of the non-native oats dominated annual grassland habitat and does not constitute a natural community of special concern.

While the CNDDB list of special-status plant species is exhaustive, most of the species and natural communities are associated with undisturbed lands and specific soil types, such as serpentine outcrops or specific habitat characteristics such as seasonal wetlands. The DWE field survey was conducted during the spring 2021 at peak floristic expression and represents a thorough floristic inventory and rare plant survey for this somewhat disturbed infill site.

The botanical survey resulted in observation of one CNPS List 4.B (a watch list) San Luis ATTACHMENT 3

Biological & Wetland Resources Assessments – Regulatory Compliance Specialist Obispo (Cambria) morning glory that is a species of limited distribution but has current distribution from San Luis Obispo County to northwestern Santa Barbara County, with historic herbaria records as far north as Sonoma County. Recent observations in the record have found it throughout coastal and inland San Luis Obispo County reducing the significance of its occurrence and local rarity at any one location. No other rare, threatened, or endangered plant species or remnants thereof were observed within the project area during the DWE appropriately timed 2021 floristic inventory and rare plant survey. While only one survey was conducted, the grassland project areas were at peak expression of grasses and broadleaf forbs that adequately captured the flora for the purposes of project evaluation and assessment of potential rare plant impacts.

Special-Status Wildlife
The CNDDB search revealed the recorded occurrences of 24 special-status wildlife in the region of the project site (see Table 2). Special-status wildlife species known from the region evaluated for this study have specific habitat use requirements (i.e., specific soils, terrestrial or aquatic). Given the infill urban setting with a limited diversity of the non-native grassland species, no associated special-status grassland wildlife species area expected to occur. The willow riparian creek corridor habitat has a low potential for several riparian associated species, but the lack of understory shrub and natural debris limits the suitability for any special-status wildlife species. This conclusion is discussed further below.

Riparian/Aquatic Species – The CNDDB has recorded occurrences of the steelhead, California red-legged frog, foothill yellow-legged frog, coast range newt, San Luis Obispo pyrg (a freshwater snail), and western pond turtle. These are all highly aquatic species for all or a significant portion of their lifecycle and suitable habitat is not represented in the seasonal creek running through the project site. The lesser slender salamander and twostripped garter snake can occur in riparian habitat. The lack of accumulated cover (vegetation and debris) and likely sheet flows throughout the bottom of the corridor does not represent suitable habitat for these two species. Vernal pool fairy shrimp (Branchinecta lynchi) require static seasonal pools that do not occur within the project site. Tricolored blackbirds require tule/cattail stands or thickets for nesting that do not occur on the project site. The yellow-breasted chat, loggerhead shrike, and Cooper’s hawk have a low potential to use the onsite riparian corridor for nesting or foraging. The Monterey dusky footed woodrat can occur in riparian areas, however, no woodrat middens (nests) were observed onsite.

Upland Species – The compacted and heavy clay soils are unsuitable habitat for the American badger, coast horned lizard, or northern California (silvery) legless lizard that need sandy friable soils. No evidence of these species or suitable soils were observed during DWE field surveys. The burrowing owl can winter in the San Luis Obispo area but nests further inland, however, the site lacks sufficient grassland and ground squirrel burrow habitat. The Crotch bumblebee (Bombus crotchii) ranges throughout California to Baja typically found in ATTACHMENT 3

Biological & Wetland Resources Assessments – Regulatory Compliance Specialist wildflower rich grasslands. The project site is low in wildflower diversity and no bumblebee nests were observed during DWE field surveys. The monarch butterfly uses forests and tree stands typically near the coast for fall and winter roosts. The onsite low stature riparian habitat does not represent suitable monarch butterfly winter roost habitat. The CNDDB has recorded occurrences of four bat species that are known from forest and woodland habitats, but use caves, mines, buildings, trees and rock crevices for maternity colonies and roosts. No suitable roost structure occurs within the project site, so these species are not expected to occur. The American badger is known from grasslands in the region with abundant small mammal prey base. No evidence of badger dens was observed on the project site during DWE field surveys.

4.3 REGULATORY SETTING
The remnant open creek channel and riparian corridor may represent jurisdictional waters of the U.S./State pursuant to the Federal Clean Water Act Section 404, California Porter Cologne Water Quality Control Act, and California Fish and Game Code Section 1600 Lake and Streambed Program. Depending on the location of project impacts into the riparian corridor or active creek bottom, project elements encroaching into the riparian corridor such as the proposed bridge may need permits or authorizations from the U.S. Army Corps of Engineers (Corps), Regional Water Quality Control Board (RWQCB), and/or the California Department of Fish and Wildlife (CDFW). Current bridge design indicates the proposed span bridge footings would be constructed above the 100-year water surface elevation and fall well above the active creek channel with only minor impacts from riparian tree removal and trimming. As such, no fill would be placed in the Corps waters of the U.S. jurisdiction and no permit would be required by the Corps. However, the RWQCB and CDFW may still require permits for the work through the riparian corridor.

The CDFW Fish and Game Code of California Sections 3503 and 3503.1 (raptors specifically) prohibits the destruction of active nests of birds. Active bird’s nests must be avoided from destruction and protected from nest failure during project activities as there is no permit available for destruction of an active nest.

5.0 PROJECT IMPACTS AND RECOMMENDED MITIGATION MEASURES The proposed project would develop non-native annual grassland habitat for the residence allowable building area of 0.36 acre and ADU building area of 0.09 acre, while preserving the riparian corridor and required setbacks of 0.78 acre. Construction of the bridge across the riparian corridor connecting the west and east building areas would require removal of one multi-trunk willow (mostly horizontal laying trunks with numerous small vertical shoots) and one small coast live oak (less than 4” dbh) (see Tree Survey Plan Sheet C2). Other willow canopy may be trimmed for placement of the span bridge on the footings. The bridge location has been sighted in an open area of the riparian corridor to minimize impacts on riparian vegetation.

David Wolff Environmental, LLC 841 PATRICIA DRIVE RESIDENTIAL PROJECT BIOLOGICAL RESOURCES ASSESSMENT |8
Biological & Wetland Resources Assessments – Regulatory Compliance Specialist The proposed project preservation of the riparian corridor with required setbacks totaling

0.78 acre of the 1.41-acre site would be consistent with the COSE and Land Use Element policies to maintain an open channel, respect natural features, and protect and enhance creeks and wildlife habitat and corridors.

IMPACT 1: NESTING BIRDS
The proposed conversion of the disturbed annual grassland habitat and tree removal/trimming in the riparian corridor for the proposed bridge may impact ground nesting and/or tree nesting bird species if activities are conducted during the nesting season typically February 1st to August 31st. To reduce potential impacts to nesting birds to a less than significant level, the following mitigation measures are recommended:

MM BIO-1: Vegetation removal and initial site disturbance for any project elements shall be conducted between September 1st and January 31st outside of the nesting season for birds. If vegetation removal is planned for the bird nesting season (February 1st to August 31st), then preconstruction nesting bird surveys shall be required to determine if any active nests would be impacted by project construction. If no active nests are found, then no further mitigation shall be required.

If any active nests are found that would be impacted by construction, then the nest sites shall be avoided with the establishment of a non-disturbance buffer zone around active nests as determined by a qualified biologist. Nest sites shall be avoided and protected with the non-disturbance buffer zone until the adults and young of the year are no longer reliant on the nest site for survival as determined by a qualified biologist. As such, avoiding disturbance or take of an active nest would reduce potential impacts on nesting birds to a less-thansignificant level.

IMPACT 2: RIPARIAN HABITAT IMPACTS
The proposed bridge has been located in a relatively open area of the onsite riparian habitat.

However, some willow and small oak tree removal, and other willow tree pruning may be required to construct footings and place a clear span bridge structure over the creek on the footings. Ten 5 to 15-gallon coast live oak trees will be planted in riparian setback as part of the project to offset tree removal/trimming impacts. The bridge structure construction may result in fill of waters of the U.S./State (current plans show bridge work above Corps jurisdiction) and removal of riparian habitat that may require regulatory compliance from federal and state agencies. Impacts resulting in fill of waters of the U.S./State would be considered a potentially significant impact. To affirm acceptable regulatory compliance to reduce potential impacts on waters of the U.S./State to a less than significant level, the following mitigation measures are recommended:

Page 786 of 1373 ends

David Wolff Environmental, LLC 841 PATRICIA DRIVE RESIDENTIAL PROJECT BIOLOGICAL RESOURCES ASSESSMENT |9
Biological & Wetland Resources Assessments – Regulatory Compliance Specialist MM BIO-2: The applicant shall obtain Clean Water Act (CWA) regulatory compliance in the form of a permit from the Corps or written documentation from the Corps that no permit would be required for the proposed road crossing. Should a permit be required, the applicant shall implement all the terms and conditions of the permit to the satisfaction of the Corps. Corps permits and authorizations require applicants to demonstrate that the proposed project has been designed and will be implemented in a manner that avoids and minimizes impacts on aquatic resources to the extent practicable. Compliance with Corps permitting would also include obtaining and CWA 401 Water Quality Certification from the Regional Water Quality Control Board (RWQCB). Absent a Corps permit, the applicant may be required to obtain waste discharger requirements (WDRs) from RWQCB for riparian habitat waters of the State impacts. As such, Corps and/pr RWQCB regulatory compliance would reduce potential impacts on waters of the U.S./State to a less-than-significant level.

MM BIO-3: The applicant shall obtain compliance with Section 1602 of the California Fish and Game Code (Streambed Alteration Agreements) in the form of a completed Streambed Alteration Agreement Notification or written documentation from the CDFW that no agreement would be required for the proposed span bridge crossing through the riparian habitat. Should an agreement be required, the property owners shall implement all the terms and conditions of the agreement to the satisfaction of the CDFG. The CDFG Streambed Alteration Agreement process encourages applicants to demonstrate that the proposed project has been designed and will be implemented in a manner that avoids and minimizes impacts in the stream zone. As such, regulatory compliance would reduce potential impacts on waters of the State to a less-than-significant level.

6.0 CONCLUSIONS
Based on the findings described above establishing the existing conditions of biological resources and regulatory setting within the project site, and incorporation of the recommended mitigation measures, implementation of the proposed project would not result in any substantial adverse effects on biological, botanical, or riparian habitat resources.

Therefore, with mitigation measures incorporated into the project, direct and indirect project impacts on biological resources would be considered to be less than significant.

SUBJECT: Biological Resources Assessment Addendum for the 841 Patricia Drive Project (ARCH-0040-2021; APN 052-520-063), City of San Luis Obispo, CA David Wolff Environmental (DWE) is pleased to submit this Biological Resources Assessment Addendum (BRA Addendum) to the May 13, 2021 Biological Resources Assessment (BRA) for the 841 Patricia Drive residential development project (proposed project) in the City of San Luis Obispo (City), CA (APN 052-520-063; ARCH-0040-2021).

This BRA Addendum has been prepared in response to the October 21, 2021 SWCA peer review email of the BRA and following the project site visit on October 22, 2021 with the project team, City, and SWCA staff. DWE Principal Ecologist David Wolff conducted a follow up field reconnaissance on October 28, 2021 to further evaluate project site existing conditions and analyze proposed project impacts to address the peer review comments. The following addresses the five biological resources comments from the October 21st SWCA BRA peer review email.

1.0 RIPARIAN IMPACTS FROM BRIDGE CONSTRUCTION
The proposed project includes a clear span bridge with footings placed above the active braided creek channel. No ground disturbance in the active braided creek channel bottom would occur. As shown on the attached Sheet L-1 approximately 17 small coast live oak saplings would be removed, and between 20-30 arroyo willow stems from four trees may need removal or pruning to place the bridge and footings. This is considered the maximum amount of vegetation removal needed and will be minimized to the extent feasible during construction.

In order to fully mitigate for the oak and willow tree riparian habitat removal, the proposed project includes planting of 20 coast live oak, 4 California bay laurel, 4 California sycamore 1-gallon trees, and 20 willow sprigs planted throughout the channel bottom as shown on attached Sheet L-1. Final planting locations will be field verified for optimal placement during construction. The proposed compensatory riparian mitigation will add plant species diversity and density to increase the riparian habitat values. Plantings will be provided supplemental irrigation for three years, and maintained and monitored for five years, to meet an 80 percent survival success criteria after two years without supplemental irrigation.

2.0 SAN LUIS OBISPO (CAMBRIA) MORNING GLORY
The BRA rare plant survey observed the CNPS List 4.2 (a watch list of plants with limited distribution) San Luis Obispo (Cambria) morning glory (Calystegia subacaulis ssp. episcopalis) sparsely on the western side of the creek with more frequent occurrences on the eastern grassland flat. Interesting occurrence because the site has been previously disturbed from fill and installation of a sewer line. The San Luis Obispo (Cambria) morning glory is a species of limited distribution but has current distribution from San Luis Obispo County to northwestern Santa Barbara County, with historic herbaria records as far north as Sonoma County. Recent observations in the record have found it throughout coastal and inland San Luis Obispo County reducing the significance of its occurrence and local rarity at any one location. The CNPS recognized the greater range and distribution of this species and reduced its rarity listing from List 1.B. to List 4.2 in 2011.

David Wolff discussed the matter of impacts on the San Luis Obispo (Cambria) morning glory with City Natural Resource Manager Bob Hill. It was agreed that while this species was a CNPS List 1.B. at the time the Conservation and Open Space Element was adopted in 2006, its current status as a List 4.2 plant in 2011 should prevail in any current project analysis.

Given it has been widely observed throughout the City (and beyond), and the infill nature of this previously disturbed project site, it was further agreed that impacts on the San Luis Obispo (Cambria) morning glory would be considered less than significant and not require any mitigation.

3.0 CALIFORNIA RED-LEGGED FROG
The BRA established the onsite creek as a remnant above ground reach emanating from a culverts on the project site and undergrounding several block away near Westmont Avenue.

There does not appear to be any readily identifiable connection to any downstream waters or aquatic habitat. “Upstream” is urban runoff and the rapid draining steep Bishop Peak hillside.

This remnant reach of creek is surrounded by residential development with the steep hills of Bishop Peak to the west. Review of aerial photography does not show any evidence of ponds in the surrounding hillsides or residential areas that could represent a source of California red-legged frogs to disperse and occupy the onsite reach of creek. Additionally, there is no undeveloped land around the project site (only residences) that could be an entry to overland movement by frogs should they occur somewhere in the surrounding lands (again no suitable aquatic habitat identified in aerial photographs).

The DWE field survey on October 28th followed an approximately 1.4-inch rainfall event several days earlier. There was only evidence of flows from the rain event within the narrow braided channels with no sheet flow across the floodplain. It appeared there was barely enough flows even from the short but substantial rain event to push accumulated leaf litter ATTACHMENT 4

Page 800 of 1373 ends

David Wolff Environmental, LLC 841 PATRICIA DRIVE RESIDENTIAL PROJECT BIOLOGICAL RESOURCES ASSESSMENT ADDENDUM |3
Biological & Wetland Resources Assessments – Regulatory Compliance Specialist beyond the limits of the braided narrow low-flow channels. No standing or pooled water remained from the obvious rain event flows on the project site supporting the BRA findings that the site lacks the required aquatic habitat for the California red-legged frog. The proposed project would not alter the creek channel or change any of the inputs so post project conditions would be unchanged and remain lacking suitable aquatic habitat to attract any California red-legged frogs should they even occur from within either the limited available above ground creek system, or the surrounding lands.

4.0 TREE IMPACTS
The attached Sheet L-1 shows the locations and quantities of the maximum number of trees likely needing removal for the bridge construction. Section 1.0 above provides a conceptual tree replacement compensatory mitigation plan with a five-year success monitoring period.

Sheet L-1 also provides a conceptual planting plan for the replacement trees also described in Section 1.0 above.

5.0 NATIONAL WETLANDS INVENTORY MAPPING
The National Wetlands Inventory is a very broad-brush remote sensing approach to mapping wetlands and other waters. The unnamed drainage running along the existing driveway referred to in the peer review comments appears to be a mapping convention to “connect the dots” between the steep hillside drainage pattern and the readily identifiable creek corridor.

BRA Figure 4 Photo 1 provides a view west down the driveway elevated above the street to the hillside demonstrating the lack of any connecting waters. This determination is also shown on BRA Figure 3 and was corroborated during the October 22nd City, SWCA, and project team field meeting.

Thank you for the opportunity to provide this BRA Addendum to address the peer review comments for use in completing the City’s environmental review for the proposed project.

Very truly yours,
David K. Wolff

This message is from an External Source. Use caution when deciding to open attachments, click links, or respond.

Dear Mr. Oetzell,
I would like to specifically comment on the San Luis Obispo County CEQA Air Quality Handbook which evaluates project-specific impacts and determines if potentially significant health impacts could result from a project. "The project site is a flag lot and is directly adjacent to residential development in all directions. Construction activities, such as excavation, grading, vegetation removal, staging, and building construction would result in construction vehicle emissions and dust that will impact neighbors within 1,000 feet." Initial Study Environmental Checklist, page 18.* Earth Moving - 841 Patricia plans
In the recent past, we have had neighbors diagnosed with Valley Fever. To provide context, it's important to understand how much earth moving will be involved during proposed construction.
"Project construction would require approximately 1,932 cubic yards (cy) of cut and 650 cy of fill, for a total of 2,582 cy total cut/fill. Construction is anticipated to last approximately 24 months. Construction would result in approximately 35,000 square feet (0.8 acre) of ground disturbance and would replace approximately 12,540 square feet of previous surface area." Valley Fever - How does it relate to the proposed project at 841 Patricia Drive? SLO County has the third-highest number and rate of cases in California, after Kern and Kings counties. With Valley Fever, knowledge is power. Valley Fever (or Coccidioidomycosis) is an infection caused by inhalation of spores of the fungus, Coccidioides, which lives naturally in the soil. It is highly endemic in Arizona and some areas of California, including San Luis Obispo County, Monterey County and the Central Valley region.

SLO County Health Department - "Although the fungus that causes Valley Fever can live anywhere in our county, many local cases are from the northern part of the county where conditions are especially dry and windy. When this soil is disturbed by wind, construction, or other causes— people can breathe in the spores from this fungus and develop Valley Fever. " Please include this letter in the case file for 841 Patricia Drive. (City Files EID-0547-0201, ARCH-0040-2021)

Subject: CREEK SETBACK EXCEPTIONS - 841 Patricia Drive
Date: Tuesday, October 4, 2022 11:07:57 AM
This message is from an External Source. Use caution when deciding to open attachments, click links, or respond.

Dear Mr. Oetzell,
The City's Zoning Regulation 17.70.030 clearly establishes the purpose of Creek Setbacks. First, these setbacks are intended to "protect scenic resources, water quality and natural creekside habitat, including opportunities for wildlife habitation, rest, and movement." The second stated purpose is "the restoration of damaged or degraded habitat, especially where a continuous riparian habitat corridor can be established".

Regarding Creek Setback Exceptions, we understand that there are eight findings that must be made in order for the Director to approve such an exception. Within the design of the proposed project at 841 Patricia Drive, we believe there are five findings that are not possible to meet. They are:

1. Minimal impact should mean that there is no development in the creek itself.

The location and design of the proposed bridge will absolutely not minimize impacts to scenic resources, water quality, and riparian habitat, including opportunities for wildlife habitation, rest and movement.

4. There are no circumstances applying to this site, such as size, shape or topography that would deprive the property privileges enjoyed by other property in the vicinity with the same zoning.

5. This exception would constitute a grant of special privilege. A creek setback exception would be inconsistent with the limitation upon other properties in the neighborhood.

7. Site development can be feasibly accomplished with a redesign of the project.

8. Redesign of the project would not deny the property owner reasonable use of the property given comparable development scale in the neighborhood, even on a larger than average lot.

We believe that incorporation of five of the mitigation measures into the project at 841 Patricia Drive will not reduce the significant impacts of the project. Please include this correspondence in the case file: EID-0547-0201, ARCH-00402021.

Sincerely,
Jim and Kathy apRoberts

Attn: Walter Oetzell, Assistant City Planner
Dear Mr. Oetzell,
The purpose of this letter is to provide comments to the initial study environmental checklist and draft Mitigated Negative Declaration (MND) for 841 Patricia Drive, San Luis Obispo in City Files EID-0547-2021 and ARCH-0040-2021 and per the Notice of Availability and Intent to Adopt a Draft Mitigated Negative Declaration for the Michaels Residence Project.

As property owners adjacent to the 841 Patricia parcel, we have concerns regarding the extent of development within Twin Ridge Creek, the creek set-back requirements and the City’s declaration of a Riparian Wildlife Corridor on the property. The initial study and MND provide for actions to mitigate impact to Twin Ridge Creek and Wildlife Corridor; however there are errors, omissions and potentially additional mitigations necessary to reduce impact to this sensitive environment on the property.

We appreciate the desire to develop the property at 841 Patricia Drive, and given the unique characteristics of the property it is important to preserve wildlife and the creek environment. We believe it is possible to develop on this parcel without harming the creek and wildlife corridor by placing all structures within the building envelope on the west side of the creek and thus not disturb the creek area or wildlife corridor. In doing so, much of the MND actions would become unnecessary and thus preserve this precious environment within the neighborhood. We do not claim to be land use planners, so simple common sense is what is driving our intentions for providing comments.

Attached please find comments to the documents including proposed additional information needed in order to correct and or include within the study and MND.

Please feel free to contact us should you have any questions regarding these comments.

Sincerely,
Victoria Frydenlund Daniel Alvarez

1 Last paragraph states, “In addition
to the residence and ADU, the
project includes…a small access
bridge over Twin Ridge
Creek…The bridge access would
be a maximum 12 feet wide and is
envisioned to accommodate small
vehicles (e.g. electric cart) to allow
access to the ADU”.

The description does not include the length of
the bridge. According to the project plans in
Attachment 1, the bridge is described as 55
feet long by 12 feet wide. The description
states that the bridge is to accommodate small
vehicles (e.g. electric cart). The size of this
bridge and the permeable driveway and
parking area surrounding the ADU will
accommodate standard vehicles and trucks as
it is as wide as a freeway lane or single lane in
a street. If the bridge is envisioned to
accommodate small vehicles such as an
electric cart (golf cart), those vehicles are
typically 48” wide and thus the bridge should
be reduced in width for that type of vehicle. In
doing so, it would allow for less destruction
within the creek and wildlife corridor.

The description should be revised to include
the length of the bridge and the MND should
recommend reducing the width of the bridge to
6-8 feet wide to accommodate the envisioned
small vehicles e.g. electric cart.
2 In the fourth paragraph and Table 1
it states “The project as proposed
would provide a minimum set-back
of 5 feet from the interior side
yards, 15 feet from the rear
property line and 20 feet from a line
representing the edge of the
riparian vegetation associated with
the creek.” In the paragraph after
Table 1, it states “The project
includes a creek set-back
exception to allow an exception to
the creek set back requirement for
placement of the bridge and
associated footings and supports
within the set-back area and for
any encroachment of associated
paving and vehicle parking area
into the required creek set-back
area”
These statements in paragraph 4 and Table 1
are in conflict with the statement about the
creek set-back exception. The information in
the fourth paragraph and Table 1 should be
revised to state that there is an exception to
the creek-set back and the proposed minimum
setbacks are zero (0) for creek set-back due to
the bridge, associated vehicle roadway,
paving/parking and the exceptions being
requested. In addition Table 1 states the
allowed/required set-back for the ADU is 4 feet
per city code, but for this property there is a
sewer line easement that requires a 15 foot
set-back and the 15 feet plus 4 feet should be
listed in Table 1 under allowed/required.
2 In the second paragraph it states,
“Other design features include
concrete steps, stone paving, grass
paving and a stone clad-wall”.

This description is incomplete as the design
includes per Figure 2 (on page 6) includes a
swimming pool. Furthermore, per Figure 2 the
design includes a wall within the creek setback area but is not described in this section of the document. The wall height is depicted in
the project plans as 5.5 feet above ground and

is shown to span entirely in the set-back.

Please revise this information to include the
pool and that the 5.5 foot wall and roadway is
entirely within the set-back area. The wall
should be included in what is being requested
in the exception for the set-back area.
2-3 The last sentence on page 2
states, “Without the bridge
crossing, this eastern portion of the
site would not be accessible.”
This sentence appears to be incomplete in
terms of the type of accessibility being stated.

The eastern portion of the site is accessible by
foot based upon the numerous visits to the site
by the project manager, the project planner
and City staff. Does this sentence imply the
eastern portion is not accessible by a vehicle?
If so, it should be revised to be clear on what
type of access in not accessible.
3 In the fourth paragraph there are
statements that “The project would
include installment of expanded
infrastructure to connect new
development to existing City
facilities. Utilities serving the ADU
would need to cross the on-site
portion of Twin Ridge Creek. The
project’s development plans
include two potential approaches
for the necessary extension of
utilities to the ADU 1)
trenching/undergrounding the
utilities below the creek or 2)
including the utilities in the bridge
span either handing (hanging?)
from the bridge or within the bridge
decking/enclosure. Because both
possibilities are shown on the
project plans, this environmental
assessment assumes that the
project proposed could include the
trenching/undergrounding of the
utilities below the creek as this
approach would be the most
environmental impactful”.

What is the basis of the assumption that
trenching/undergrounding would be most
impactful to the environment? Would this type
of activity impact the trees if the
undergrounding was sufficiently deep
underground to not disturb the trees and
vegetation? It is also unclear in the plans
provided in Attachment 1 that the utilities
would be placed underground as it appears
they are alongside the bridge. There is no
description in the plans that the utilities will be
trenched/undergrounded. Please clarify where
in the plans it is stated the utilities will either be
underground or on the bridge span.

Given the sensitive nature of Twin Ridge
Creek and Riparian Wildlife Corridor, it would
be a better option to develop the ADU on the
western portion of the parcel within the
building envelope and thus mitigating all
impacts to the creek and set-back. Why isn’t
there a mitigation calling for revised
conceptual plans that would not disturb the
creek and creek-set back areas at all?
16 In the fourth paragraph in the
Evaluation section it states, “The
project site is surrounded by
existing single-family residential
units; therefore, there are sensitive
receptor locations located in all
directions”. The next paragraph
This section of the evaluation does not include
information regarding Valley Fever
(coccidioides sp.) infections and the hazards
related to Valley Fever. Valley Fever is known
to be in San Luis Obispo County, which is
amongst the three highest counties in the state
to harbor the fungus. Thus, there is risk of

further states that “Naturally
Occurring Asbestos (NOA) has
been identified as a toxic air
contaminant by the CARB. Any
ground disturbance proposed in an
area identified as having the
potential to contain NOA must
comply with the Airborne Toxics
Control Measures (ATCM) for
Construction, Grading, Quarrying,

infection to persons exposed to the airborne
spores from this fungus. This risk should be
included in the evaluation and proposed
mitigations should be included to minimize the
risk to both workers and adjacent neighbors
from the significant disruption of the ground for
this project (0.8 acres out of 1.4 acres
according to the plans). There should be
sampling and testing for this fungus in the
ground similarly to the Asbestos testing by the
retention of a geologist as in AQ-3 on Page

20. There should be a separate mitigation
defined for the risks associated with Valley
Fever. Neighbors, not just those adjacent,
should be notified of the risks of NOA and
Valley Fever. Furthermore, are the mitigations
listed in AQ-2 sufficient to reduce the risk and
harms from Valley Fever? If not additional
mitigations should be proposed. Reference:
https://www.cdph.ca.gov/Programs/CID/DCDC
/Pages/Coccidioidomycosis.aspx
24 Under section 4-Biological
Resources, Coopers hawk is listed
in Table 4, Special-Status Animal
Species Recorded by the CNDDB.

It is described as a potential to
occur as “Low potential in remnant
small patch of riparian habitat”.

On numerous occasions we have observed a
Cooper’s hawk on our back fence which is
adjacent to the eastern portion of 841 Patricia.

Hawks hunt for prey in the Wildlife Corridor on
841 Patricia and carry their prey to our fence.

The potential is much higher for Cooper’s
hawk to reside and use the riparian corridor
within Twin Ridge Creek. It is unclear the basis
of this low occurrence assessment. It is
recommended to revise this statement to
Moderate to High occurrence since we have
observed this bird to be present in the Riparian
Wildlife corridor.
27 Section (d) there is a statement
that “Twin Ridge Creek flows onto
the property through underground
culvert under Patricia Drive and
again along Westmont Ave. The
lack of a consistent open channel
impedes larger wildlife, such as
deer from effectively using the
creek as a movement corridor.”
This statement is incorrect for a couple points.

Specifically, 1) there are additional flows from
the storm drains located at 221 Twin Ridge
Drive and across the street from 221 Twin
Ridge Drive. This location is a low point from
either end of Twin Ridge Drive. These two
collection points drain all of the runoff into
Twin Ridge Creek. During the rainy season,
these two storm drains empty large volumes of
run-off into Twin Ridge Creek; and 2) we
observe deer on a regular basis using the
creek and riparian corridor to move through
841 Patricia and surrounding areas. One
recent observation was on September 23,
2022 where there was a young buck, a doe

and fawn using the creek corridor.

Furthermore, in Attachment 3, the Biological
Resources Assessment, it states “the site can
provide habitat for a variety of wildlife species
that have become adapted to the urban
environment such as raccoons, opossums,
skunks, with evidence of deer, gopher and
ground squirrels observed”. We have
observed these animals as well as rabbits,
turkey vultures and wild turkeys. The sentence
on page 27 should be revised to be consistent
with the BRA report and reflect that deer and
other wildlife actually do use the Twin Ridge
Creek as a movement corridor.
28-29 Mitigation Measures, Bio-3: “…The
Applicant shall provide copies of
the permits/authorizations from
affected resource agencies,
including a final revegetation plan
that is consistent with the
revegetation plan provided in the
Addendum to the Biologic
Resources
Assessment”.(Attachment 4)
“Vegetation removal shall be kept
at the minimum necessary for
bridge clearance and construction
of the necessary footings and
supports. Initial removal of
vegetation shall be monitored fulltime by a qualified biologist, and weekly spot-check monitoring shall
continue throughout construction of
the bridge structure.”
Why doesn’t this mitigation measure
specifically state the minimum requirements
for replanting trees that were removed? The
BRA addendum in Attachment 4, proposes to
replant the up to 17 oak trees with 1 gallon
trees and to replace the Arroyo Willow’s with
20 willow sprigs. According to the City’s Tree
Regulations (Municipal Code 12.24), per

12.24.090 (C.2), removal of a tree in a creek
set-back area requires a permit. Therefore, it
should be clearly stated that there needs to be
a permit requested to remove any trees in the
creek set-back area. Some of these trees are
being removed within the creek proper.

Section 12.24.090(J), Compensatory Tree
Planting, states “Tree removals authorized
under subsection E or F of this section shall
be compensated by planting a minimum of one
new tree for each tree authorized to be
removed when planted on the same property
(on site).” Further in this section is a table
indicating the size of tree to be replanted
based upon diameter of the tree removed and
the City’s engineering standards. According to
this table, trees that are between 0.75” and

1.5” are to be replanted with a 15 gallon tree.

Trees between 1.5” and 2.5” are to be planted
with a 24” box. However, according to the
proposed replanting plan in the BRA
addendum, the sizes of the trees are 1 gallon
for the Oak trees and sprigs for the Arroyo
Willows. Bio-3 should be revised to
recommend the same standards as defined by
the City Code for Tree Removal 12.24.090 and
to require larger trees to be replanted to

ensure revegetation of the creek corridor.

What are the implications if the project causes
more trees that defined in the BRA addendum
need to be removed?
We strongly urge the City to preserve this
wildlife corridor by asking that the project be
redesigned to mitigate impacts to the creek by
building all dwellings on the west side of the
building envelope.
29 The conclusion states, “The project
would be set-back 20 feet from the
approximate top of bank of Twin
Ridge Creek and would not conflict
with local plans or policies for
protection of biological resources
with implementation of the
identified mitigation measures.”
This statement is incorrect. It should be
revised given that the project is not set-back
20 feet from the approximate top of bank
because the bridge and roadway encroaches
both the creek set-back and creek itself. The
plans do conflict with local plans and policies
and thus the need to mitigate harms and risks
as well as requiring a request for an exception
to the set-back criteria defined by City
Municipal Code. This conclusion needs
revision for accuracy to the facts of the
proposed development.
38 Greenhouse Gas Emissions-Table
6 “The project would include a
mixed-fuel building. As proposed,
the project would document
compliance with the City’s Energy
Reach Code on final construction
plans to be approved by the City.”
This statement should reference Attachment 1,
Project Plans to be specific where this
commitment is proposed. As well, is it either
dwellings or just the main house that is mixed
fuel? It should be clear that all calculations
are based upon which dwellings.

Given the mixed fuel use with this project, it
should be very clear that the project should be
fully compliant with CBC requirements for
mixed fuel dwellings.
40-42 Hazardous and Hazardous
Materials
This evaluation does not include the hazard of
airborne illness due to the Valley Fever fungus
(Coccidioides sp). This section should be
revised to be consistent with the Air Quality
Section regarding this risk of hazard within the
ground to be disrupted during construction.

44 The evaluation in paragraph (b)
states, “Implementation of the
project would result in 12,540 sf of
new impervious surfaces including
a single-family residence, an ADU
and other hardscapes”. This
paragraph also states “To further
allow for groundwater infiltration
on-site, the project would maintain
the on-site creek and associated
corridor, construct driveways with
permeable pavers and reduce
driveway width where feasible”.

What is meant by other hardscapes? This
should be revised to be specific to include
walkways, a swimming pool, pool deck, patios,
etc.

The next statement quoted is not consistent as
while the creek may remain intact, there is a
55 foot by 12 foot steel bridge constructed
within the creek. This fact should be explicitly
stated. Furthermore, there is nothing stated in
the initial study to remove or reduce the
driveway width where feasible, so this point
should also be revised. There should be a
specific point to reduce the size of the bridge
and driveways to be consistent with the use of
an electric cart as previously stated in the
document.

The project should be redesigned to mitigate
impacts to the creek by building all dwellings
on the west side of the building envelope.

Preliminary Hydrology Study
prepared by Chacon Associates,
LLC (Attachment 5) for the project,
the proposed bridge would be
required to be a minimum of 2.5
feet above the creek bottom to
allow for potential 100-year flood
flows.

Is the 2 feet of freeboard recommended
sufficient to mitigate flooding especially from
debris that could be carried in Twin Ridge
Creek to the bridge? Should there be
additional clearance for flows given the
topography of the site and creek area? In this
era of climate change, is a 100 year flood
standard reasonable? We have observed
flooding of this area in the past given the creek
channel is very shallow. We recommend there
be additional mitigations to address flooding
risk from the alterations to the creek due to
construction of the bridge. Those mitigations
should include removing the bridge from the
plans and building the ADU on the western
side of the property.
45-46 Land Use Planning This section does not include the points that the project requires an exception to the creek
and creek set-back regulations in the City
Municipal Code. This section should be explicit
that while the use is consistent with the zoning
of the property, the project is requiring
exceptions in order to build an ADU on the
eastern portion of the property. The impacts
could be reduced if the project did not build on
the eastern portion of the property and
maintained all dwellings within the western
side of the property.

47-50 Noise: On page 48, the paragraph
under Table 7 states “the municipal
code also states that construction
activities shall be conducted in a
manner where technically and
economically feasible, that
maximum noise levels at affected
properties will not exceed 85 Aweighted decibel (dBA) at mixed residential uses”.

This statement is incorrect. This is not a mixed
residential use (residential/commercial) as
defined in the City Code for Noise Control9.12. This project should be defined as residential per 9.12.020-Definitions.

Furthermore, under 9.12.060, Exterior Noise
limits states, “At residential properties, the
maximum noise level from 7am-7pm daily
except Sundays and Holidays is 75 dBA.

Thus, the statement on Page 48 should be
revised to reflect the City Code for Noise
Control of 75 dBA. Furthermore, the
equipment listed in Table 8 on page 48
exceeds the Noise Control limits. It is unclear
whether the mitigations listed in N-1 to N-3 are
sufficient to reduce the noise levels to an
acceptable level below 75 dBA. Further
evaluation is warranted and subsequent
mitigations to reduce the noise level to the
allowable maximum limit.

(b) it states “The project’s
estimated water demand is
08af/yr., which would be provided
by the City’s water supply.” And
“Development of this site is
consistent with the City’s longrange planning documents, and thus has been anticipated by the
City’s water supply planning.”
Does this evaluation take into account the
water usage by having an in-ground pool at
the property? It should be clearly stated in the
evaluation that the estimates include not only
used based upon the number of residents, but
also that there is a swimming pool planned for
the project.

This section on does not include the
description of the 55 foot long by 12 foot wide
steel bridge across the creek and within the
creek area as well as the associated
driveways and parking areas necessary to
place the ADU in the eastern portion of the
property. This span creates impact to the
City’s own Municipal Code for creek
preservation and requires an exception to
those regulations. This section should state
those facts and that the exception needs
approval in order to build the bridge in the
creek which significantly impacts the creek
area. It should also be stated that other
mitigations could be done, such as to build the
project in the western side of the property
within the building envelope and thus to not
disturb the creek and maintain the creek setback.

This entire section should be revised to reflect
the numerous mitigations that are necessary in
order to mitigate the impacts of building the
bridge and associated driveways and parking
spaces for the eastern side of the property.

The proposed compliance verification for BIO2 appears to be in error since it refers to the nesting birds survey. However, BIO-2
mitigation is about the extension of the utilities
and that no trenching across the creek shall
occur for the extension of utilities. This error
should be corrected as it appears in several
monitoring programs in the MND. It would
seem more appropriate that compliance for

Summary:

We believe this initial study/MND is in need of significant revision due to errors, omissions and additional mitigations needed. We would like to express our severe concerns about the project plans specifying the steel bridge across Twin Ridge Creek will be 12 feet wide by 55 feet long.

The plans also show a retaining wall 5.5 feet high spanning about half of the property’s length.

The wall is located within the riparian vegetation and creek set-back. The proposed bridge design is sufficiently wide to allow a car or truck to drive from the main house through a roadway, cross the bridge and park at the ADU. As our home is adjacent to 841, we are very concerned that headlights will add to the already increased light pollution created by this project.

The extensiveness of this development impacts the creek and wildlife corridor to such a degree that it is not consistent with the surrounding habitat and we believe the creek’s riparian vegetation will be negatively impacted. The trees surrounding the creek and wildlife corridor are native and protected. Even with any defined mitigations, the risks to permanently damaging this sensitive environment are too high. We do not think that the scale of the bridge and driveway are appropriate for this type of development and should not be allowed due to harmful impacts to the creek, wildlife corridor and neighborhood.

Comments to Initial Study and Required Mitigations and Monitoring Programs for EID-0547-2021 11 The proposed development project should be revised to place all dwellings on the western side of the creek set-back. This redesign would mitigate all the impacts to Twin Ridge Creek due to placing the roadways, walls, parking area and extremely large bridge within the creek and setback of the riparian vegetation by eliminating these design features and need for a creek setback exception.

According to San Luis Obispo Zoning Regulations under Creek Setbacks, 17.16.025(G.4), Discretionary Exceptions,
a. Intent. Discretionary exceptions to creek setback standards are intended to allow reasonable use of sites that are subject to creek set-backs, where there is no practicable alternative to the exception. Generally, such exceptions are limited to small parcels that are essentially surrounded by sites that have been developed with setbacks smaller than those in subsection E of this section. In the case of pedestrian paths, bicycle paths and bridges, the site may be large but there are no options for avoiding a crossing of the creek or encroaching into the creek setback.

The development at 841 Patricia does not fit the intent of an exception given there are other options to develop on the 1.4 acre parcel and those options include redesign of the dwellings to all be located on the western side of the creek and within the larger building envelope of the parcel. Allowing such a large exception to the creek setback at 841 Patricia would set a damaging precedent for San Luis Obispo in this R-1 zoned area.

October 7, 2022
Dear Mr. Oetzell,
Regarding Creek Setback Exception Request for 841 Patricia Drive, San Luis Obispo:

Looking at the property at 841 Patricia Drive, the lot area contained by the minimum lot and creek setbacks and excluding the ‘flag’ for the driveway - effectively the ‘by-right’ developable envelope- is approximately 15,500 square feet. At 40% maximum coverage (6,200 square feet) this project and the ADU (5,260sf + 830sf = 6,120 sf) could be designed and constructed to be together on the west side of the creek. This very conservative approach to developable area and lot coverage clearly demonstrates the project could be redesigned to avoid the need for the requested creek setback exception - a request that is undeniably one of choice, not necessity.

Outside of the building footprints, the site development also includes a large pool, extensive patios and terraces, all choices made that inhibit the potential for the ADU to be included on the west side of the creek. With adjustments to those outdoor areas - and perhaps even by requesting a creek setback exception for the pool - additional space could be maintained on the west side of the creek and facilitate placement of the ADU without compromising separation and privacy between the two homes, and without requiring the severe impacts of installing a road and bridge to cross over and through the creek bed. The road and bridge are substantially larger impacts than the ADU itself in terms of surface area and creek encroachment.

Per the San Luis Obispo Municipal Code 17.70.030.G.4.c findings must be made to grant an exception to the required creek setbacks. Finding #4 indicates that there needs to be “circumstances applying to the site, such as size, shape, or topography, which do not apply generally to land in the vicinity with the same zoning, that would deprive the property of privileges enjoyed by other property in the vicinity with the same zoning.” Over 6,000 square feet of building footprint, large terraces, and a pool to not reflect a deprivation of privilege, is quite the opposite. Finding #7 requires that “site development cannot be feasibly accomplished with a redesign of the project.” As noted above, a redesign is entirely feasible, it just would not have a bridge. This is supported by text regarding Finding #8 that “in the case of new development (reasonable use of the property) may include less development than indicated by zoning.”
The Initial Study mentions that “without the bridge crossing, the eastern portion of the site would not be accessible.” This may be true, but the property owner has no right to vehicular access across a waterway. Undoubtedly, outside of the rainy season, access by foot across the creek would be easily achieved.

Dr. Mr Oetzell,
Thank you for your consideration of an extension to review the Notice of Availability and Intent to Adopt a Draft Mitigated Negative Declaration for the 841 Patricia Drive (APN 052-520-063) project. This is an overwhelming task for your average citizen that is not in the real estate development or legal fields. We will do our best to share our concerns. Please include this in the case file: EID-0547-0201, ARCH-00402021

1. We are curious if all parties involved within the City have actually walked the property at 841 Patricia drive and witnessed what the creek and wildlife corridor look like in person? Although the City has in place protections for the creek and the surrounding riparian area, its hard to protect something that you've never seen. Our hope is that all parties involved take the time to visit the site and to take in the surrounding area as the proposed bridge through the creek and riparian area are not what the City laws have in place to protect. We believe the owners have every right to build on their property however feel that there is ample room to have an ADU and storage shed on the main development site without having to encroach upon a protected creek, riparian area, and wildlife corridor.

2. We would like further information on the initial study environmental checklist as to why an Environmental Impact Report is currently not required? We don't feel like the Mitigated Negative Declaration truly delves into the negative environmental effects that will take place by cutting down a large quantity of naturally occurring willows along the creek to make way for a 55 foot long 12 foot wide bridge to cross the creek to get to an ADU unit and storage shed that will also impact a large portion of the riparian and wild life corridor areas.

3. HYDROLOGY/FLOODING: We have lived in this neighborhood since 2002 and have witnessed on multiple occasions heavy rainfall that has resulted in the entire open are behind our house and within the proposed shed, ADU unit, and bridge flooded with water. As homeowners that back up to the proposed project, we are extremely worried that any change to the creek flow can result in a disastrous flooding situation that can affect neighbors within the entire creek area including further downstream from the project. We don't believe the impact study takes into account current models of precipitation that could impact our area due to the adverse affects of climate change.

Last year we didn't get much annual rainfall but the one big storm we had dropped almost 7 inches of rain in a 2 day period that did cause considerable ponding and areas of localized flooding. This is a situation that could happen more frequently than previously planned for based on the traditional 100 year or 500 year storm models.

4. We would also like to challenge the report under Aesthetics letter a: This project if approved with the bridge and ADU and shed, will have a potentially significant and substantial adverse effect on a scenic vista. I'm confused as to why the initial report is checked with a less than significant impact. This may be true for the main building site but not the bridge, ADU, and shed. Not only will neighbors that back up to the project have a significant aesthetic impact but anyone walking or running on Patricia past the creek area will be exposed to an anomaly that is not congruent with the aesthetics for the rest of the neighborhood or open space. We would also like to challenge letter c: and believe that approval of the bridge, ADU unit and Shed will have a significant impact and degrade the existing visual character or quality of public views of the site and its surroundings. Under letter d) we also feel that the ADU unit and shed will create a new source of substantial light or glare which would adversely affect day or nighttime views in the area. We would like to add that having the ADU unit will not only create light pollution for our neighborhood but potential noise issues as well depending on who the owners rent the property to.

5. Land Use and Planning letter b: We would also like to challenge the finding that this project will have less than a significant impact with mitigation incorporated environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect: We believe the City has standards and laws in place to protect the creeks, riparian areas and wildlife corridors for a reason. It is one of the City's missions and to establish a precedent of approval to build a bridge, ADU unit and shed across a protected

Page 827 of 1373 ends

creek, riparian area and wildlife corridor goes against what the City of San Luis Obispo is trying to protect. If approved this project will literally pave the way for any landowner with property spanning across a creek, riparian area and wildlife corridor in San Luis Obispo to ask for an exception to build a bridge, ADU unit and storage sheds in what was once a protected area. I will reiterate, we are not against the owners building on the primary site, however feel it is unnecessary given the lot size and dimensions to encroach or build through a riparian area by removing naturally occurring protected willows over a protected creek into a wildlife corridor.

6. Biological Resources Assessment: I would like to state that in fact there are multiple areas along the creek within the building area that have ponding that can be present into late May and sometimes June depending on how much rain we received in the prior months. Years ago when my daughter was 7 or 8 years old we were cleaning up debris in the creek and were surprised and excited to find turtles in one of the ponding areas located within the proposed building site. We haven't seen turtles in a long time but haven't been specifically looking for them. We can also say with certainty that Coopers Hawk's frequent the creek and riparian areas almost daily. We have also witnessed the yellow-breasted chat on occasion. The creek and riparian areas also have many deer on a year round basis and higher rates during birthing months.

7. Is it possible for the City to post at the entrance to the 841 property the proposed project with a concept design so the community can better understand the significance of this project and how it will negatively impact the creek, riparian area, and wildlife corridor? It's easy for community members to not know what's going on unless something is visibly in place for them to read while they are out and about on a walk or run.

We appreciate the opportunity to comment on this project. We are sure there will be more questions that come up and we will share those with you in the appropriate forum.

Take care,
Jud and Nara Clark

Attn: Walter Oetzell, Assistant Planner
Dear Mr. Oetzell,
Please consider this response to the Notice of Availability and Intent to Adopt a Draft Mitigated Negative Declaration for the Michaels Residence Project (City Files EID0547-0201, ARCH-0040-2021). Project Location 841 Patricia Drive. We own and reside permanently at 847 Patricia Drive. Ours is the property immediately to the left of the Michaels' driveway and immediately in front of the main portion of the proposed residence. We are responding to a portion of The Initial Study and Mitigated Negative Declaration. Specifically we are responding to the 21-page document that is referred to as "Project Plans (Jun [sic] 17, 2022)", also sometimes referenced as Attachment 1. We are uncertain about the exact title and date of this document because dates other than Jun/June 17, 2022 appear on several pages of the document, so to make clear which document we are referencing it is included as an attachment to this email with the title we have given it - "Referenced Document".

Please consider the attachment as part of our response.

From our reading and careful review of the referenced document, it is our understanding that:

1. As shown in "Site Section 2 @ Living" (page A4?) the highest point of the residence roof will not exceed an elevation of 375.57

2. As shown in "Site Section 1 @ Garage" (page A4?) the highest point of the garage roof will not exceed an elevation of 376.48

3. As shown in the "Schematic Site Plan" (AS-1) no portion of the residence will be closer than 27' 11" to our back property line
Overall, we are favorably impressed by the plans as shown in the referenced document. More specifically, we favor the style, color scheme, and exterior materials and details of the buildings as called out in the plans. We are also happy to see the planned use of extensive permeable paving and a landscape plan that suggests the intention to use what appears to be appropriate plants, mulching, and hardscaping along with appropriate irrigation technology. We note that several plants have been called out that are favorable to birds, bees, butterflies, and other pollinators.

Landscape plans are sometimes difficult to read and interpret, in part because of the use of symbols that are very similar to other symbols on the plan; consequently, we make this note regarding the landscape plan as presented: from the Master Landscape Plan (L-1) it appears that Citrus X sinensis will be planted along the left side of the driveway parallel to our property. The ultimate height of Citrus X sinensis

Page 829 of 1373 ends

varies depending largely on cultivar selection, rootstock, and ongoing maintenance - especially pruning. In a typical residential setting most selections of Citrus X sinensis are kept at about 8' to 10' tall for convenience of harvesting, maintenance, etc.

However, many cultivars of this species can reach an ultimate height of nearly 30', especially if left unattended. At that height the plants will possibly negatively impact solar collection on existing and/or future solar panels.

Though grading and drainage are somewhat addressed in the referenced document, we want to express this concern: any changes in grading and/or drainage in the referenced project shall not cause water to flow onto or seep or otherwise permeate into any neighboring property other than what may be occurring presently.

Thank you,
Thomas E. and Mary Kay Eltzroth
