DISCUSSION Background An application was received to subdivide a parcel in the R-1 district located at 1655 Alrita Street (see vicinity map, attachment 1). The site consists of an approximately .38 acre parcel, containing one existing single-family residence and a detached garage. The applicant is requesting to subdivide the existing parcel into two lots, ultimately allowing one new single- family home in addition to the existing residence (see proposed map attachment 2). In most cases, a minor subdivision (involving four or fewer parcels) is exempt from environmental review and can be reviewed and approved by the Administrative Hearing Officer. However, when exceptions are requested, a minor subdivision is not exempt from the California Environmental Quality Act (CEQA) and, according to the Subdivision Regulations, requires review by the City Council rather than the Planning Commission. The applicant is requesting an exception to the lot depth requirement, to allow a 71-foot deep lot where the Subdivision Ordinance normally requires a 90-foot deep lot. Staff is also recommending approval of an exception that would allow a 12-foot wide driveway where a 16-foot wide driveway is normally required. The exceptions will allow the applicant to create two lots that meet or exceed the minimum lot size standards while retaining the existing house in it's present location on the property. Analysis The three primary issues associated with this project are: 1) neighborhood compatibility; 2) consistency with City policies and standards; and 3) consideration of the requested exception. Staff supports flag lots and similar minor subdivisions as an efficient way of accommodating infill development, provided site development is consistent with the neighborhood and meets all City standards. The proposed subdivision meets all standards regarding minimum lot area for the R-1 district with the exception of depth for the front lot. The proposed lot configuration will result in one lot a- i I � � Council Agenda Report MS 139-02 (Strong, 1655 Alrita Street) Page 2 to the rear of the existing residence. The rear lot will have a 20-foot wide, 70-foot deep accessway that reaches Alrita Street, with net lot dimensions of 65 feet wide by 130 feet deep. This rear lot would be considered a "flag lot". Typically, flag lot's frontage is measured from the access drive. As defined within the Subdivision Ordinance, lots that front a public street, however, measure the lot width from the public street frontage, while the depth is measured perpendicular to the public street. The parcel remaining at the Alrita Street Frontage will contain the existing residence and a proposed lot size of 71 feet deep and approximately 100 feet wide. If this lot's frontage were measured at the access driveway it would meet all standards and not necessarily require an exception to be approved. The applicant is asking for an exception to the standards to approve the reduced lot depth, although both lots will meet minimum size standards of at least 6,000 square feet. Staff has added a condition of approval to this project to utilize a single driveway as access to both properties. The proposed access portion of the new lot is actually located just north of the existing driveway location. Development of a driveway approach for the new lot would result in two driveways side by side and an unnecessary expanse of paving. The resulting lots should utilize an easement to allow access to both lots from one driveway. The Subdivision regulations stipulate a minimum driveway width of 16 feet for flag lot driveways, with a minimum setback of ten feet from the driveway for any structures. Since the proposal only includes the development of one additional property with a relatively short driveway distance, a driveway width of 12 feet would be sufficient. It should be noted, however, that a 12-foot driveway width does require approval of an exception to the Subdivision Ordinance flag lot standards (Section 16.36.230- see attachment 3). If both lots were to use the existing driveway in its present location, the driveway may not comply with the flag lot setback requirements. Staff recommends the construction of a new driveway, with an exception to the driveway width requirements that will serve both properties within the proposed access portion of the new lot. Proposed Subdivision and R-1 district Standards Code Requirements Proposed Project San Luis Obispo Zoning Code May 2002 San Luis Obispo Subdivision Regulations Parcel 1 Parcel 2 Building Setbacks: Flag lot accessway: 10 feet 20+ feet (No development plan) Side yards: 5 feet+ (No development plan) Rear yard: 5 feet+ (No development plan) Minimum lot size: 6,000 Square feet 7,029 square feet 8,000 Minimum lot depth: 90 feet 71 feet as measured from 129 feet Alrita Street Minimum lot width: 50 feet Approx. 100 feet 64 feet Minimum street frontage: 20 feet Approx. 100 feet 20 feet Driveway width(pavement): 16 feet Staff recommends a common 12-foot wide driveway to Drivewa width (easement): 20 feet serve both parcels within a 20-foot wide easement. a -a 1 Council Agenda Report MS 139-02 (Strong, 1655 Alrita Street) Page 3 1. Neighborhood Compatibility The location of the proposal is within an established residential neighborhood with single-family residences on lots ranging from approximately 7,000 square feet up to 12,000 square feet and greater. The subject parcel is approximately 16, 500 square feet, which is unusually large for the neighborhood. Although the proposed subdivision design will vary in shape and design from existing adjacent lots, the proposed lot sizes, at greater than 6,000 square feet, will be consistent with the R-1 district requirements. Approval of a subdivision will not grant special privileges to the property and any new lot created will be subject to all applicable standards of the R-1 Zoning District relating to lot coverage, density, and other standards. Development on the property will therefore be consistent with the existing neighborhood and the R-1 district. Since the new flag lot will be developed as an infill site at the rear of an existing lot, the future residence may be in close proximity to the existing rear yards of other established residences. Although the proposed lot meets the R-1 standards, staff recommends adding conditions of approval to ensure continued neighborhood compatibility. In addition to designating the resulting lot as a "sensitive" site requiring architectural review, recommended conditions of approval propose the following site development limits: • Minimum of 800 square feet of useable outdoor open space • Maximum building height of 25 feet (consistent with R-1 district), measured from actual ground level prior to construction rather than average ground level. These conditions will help ensure compatibility with the neighborhood and consistency with General Plan polices. Setting site-specific development limits on flag-lot subdivisions helps to ensure development that meets zoning regulation objectives for adequate separation between buildings, provision of landscaped areas, air circulation, protection of views, and solar access. (Section 17.16.020.A.1). The primary focus of performing architectural review on future residences will be to address viewshed, overlook, setback, parking, and architectural compatibility issues. 2. General Plan Consistency The General Plan Land Use Element (LUE) encourages maintaining a compact urban form while maintaining open space areas. Infill development, when done in accordance with City standards, is an opportunity to accomplish these primary General Plan goals. Additional LUE policies encourage new development within existing neighborhoods to be compatible in scale and character with the neighborhood. They also state that residential projects should be designed to provide adequate privacy and useable outdoor area, and should respect existing site constraints such as size and topography. Housing Element policies state that there should be a variety in the location, type, size, tenure, cost, style and age of dwellings to accommodate the wide range of households desiring to live within the City. The proposed subdivision will allow the creation of one additional parcel with a minimum size of at least 6,000 square feet within a rear yard area that is otherwise surrounded by urban development. However, as mentioned earlier, it is important for development on these infill lots a -3 Council Agenda Report MS 139-02 (Strong, 1655 Alrita Street) Page 4 to be considered through the architectural review process in order to ensure neighborhood compatibility as called for by the General Plan. General Plan policy LU 2.4.5, which describes the areas low-density residential land use designation states: "Development should be primarily dwellings having locations and forms that provide a sense of both individual identity and neighborhood cohesion for the households occupying them". Subdivision of the property, as conditioned by staff, will be consistent with General Plan Land Use Element goals with respect to City Form. 3. Requested Exceptions to City Standards The exception requested would allow a 71-foot lot depth where 90 feet is normally required. The Subdivision Ordinance requires lots in the R-I district to have a minimum depth of 90 feet and a minimum width of 50 feet. By definition in the ordinance, depth is measured from the portion of the lot that fronts the street. As measured from the street, the proposed lot nearest Alrita Street will have a depth of 71 feet, although the width of this lot will be over 100 feet. The requested lot width exception is not anticipated to negatively impact the existing neighborhood, cause a health or safety concern or set an unusual precedence. If the lot's frontage were measured from the accessway for the rear lot, the lot would meet all standard dimensions for a lot in the R-1 district. It would be possible to divide the lot without any exception if the existing residence were moved or demolished. General Plan policy discourages the demolition of-sound housing and there is no public benefit to require the existing house to be moved. The location of the existing residence in relation to the proposed property lines will still provide adequate setbacks and private yard area for the occupants, consistent with standards established for R-1 districts. As a second exception request, staff is recommending the use of a 12-foot wide driveway instead of a 16-foot wide driveway as required by the Flag Lot Requirements, Section 16.36.230 c. The Subdivision Ordinance, Chapter 16.48, specifies the following additional findings that must be made in order to approve exceptions: A. Before any exception is authorized, all of the following findings shall be made: 1. That the property to be divided is of such size or shape, or is affected by such topographic conditions, that it is impossible, impractical or undesirable, in the particular case, to conform to the strict application of the regulations codified in this title; and 2. That the cost to the subdivider of strict or literal compliance with the regulations is not the sole reason for granting the modification; and 3. That the modification will not be detrimental to the public health, safety and welfare, or be injurious to other properties in the vicinity; and 4. That granting the modification is in accord with the intent and purposes of these regulations, and is consistent with the general plan and with all applicable specific plans or other plans of the city. B. In granting any exception, the council shall impose such,conditions as are necessary to protect the public health, safety and welfare, and assure compliance with the general a -� Council Agenda Report MS 139-02 (Strong, 1655 Ahita Street) Page 5 plan, with all applicable specific plans, and with the intent and purposes of these regulations. The requested subdivision exception at 1655 Alrita Street appears to meet the required findings and is therefore supported by staff. It would be possible to divide the lot without any exception if the existing residence were moved or demolished. General Plan policy discourages the demolition of sound housing and there is no public benefit to require the existing house to be moved. Both lots will meet minimum square foot requirements for the R-1 district (6,000 square feet). The subdivision will provide a reasonable infill opportunity and the flag lot design, when implemented with staffs recommended conditions, will not be detrimental to the neighborhood. Refer to project specific findings in the resolution of approval. Environmental Review As mentioned earlier, minor subdivisions consisting of four or fewer parcels are generally exempt from environmental review unless exceptions are requested. Since an exception is requested, an initial study was prepared for the proposal. The initial environmental study (see attachment 4) addressed the project and resulted in a recommendation for a negative declaration. FISCAL IMPACTS When the General Plan was prepared, it was accompanied by a fiscal impact analysis, which found that overall the General Plan was fiscally balanced. Accordingly, since the proposed project is consistent with the General Plan, it has a neutral fiscal impact. CONCURRENCES The Public Works Department has reviewed the project and has included a list of code requirements that are standard for minor subdivisions. The Building Division noted that new residences are required to be served by underground utilities. The Fire Department had no concerns with the project. The Utilities Department noted that water allocations are still currently available on a first-come, first—serve basis. Code requirements from each of the departments are attached to the resolution of approval. ALTERNATIVES 1. The Council may approve the tentative parcel map with changed findings and/or conditions. 2. The Council may deny the tentative parcel map and or the requested exception if the necessary findings cannot be made. 3. The Council may continue discussion if additional information is needed. Direction should be given to staff and the applicant. a �� Council Agenda Report ' MS 139-02 (Strong, 1655 Alrita Street) Page 6 Attachments: 1. Vicinity map 2.

The original lot shall have frontage on a dedicated street of at least the minimum length required by these regulations for the zone in which it is located, plus the accessway required to potential rear lots. C. The accessway to the rear shall be at least twenty feet wide (with sixteen feet of pavement) for residential and conservation/open space zones, except where the accessway is more than one hundred fifty feet long it shall be at least twenty-four feet wide with twenty feet of pavement. For all other zones, the accessway shall be at least thirty feet wide with a paved roadway at least twenty-four feet wide. D. Each lot shall have yards as required by the zoning regulations. A ten-foot yard shall be provided along the access road pavement. E. The lot farthest from the street shall own the accessway in fee.

Aesthetics Geology/Soils Public Services Agricultural Resources Hazards&Hazardous Recreation Materials Air Quality Hydrology/Water Quality Transportation&Traffic Biological Resources Land Use and Planning Utilities and Service Systems Cultural Resources Noise Mandatory Findings of Si nificance Energy and Mineral Population and Housing Resources FISH AND GAME FEES There is no evidence before the Department that the project will have any potential adverse effects on fish X and wildlife resources or the habitat upon which the wildlife depends. As such, the project qualifies for a de minimis waiver with regards to the filing of Fish and Game Fees. The project has potential to impact fish and wildlife resources and shall be subject to the payment of Fish and Game fees pursuant to Section 711.4 of the California Fish and Game Code. This initial study has been circulated to the California Department of Fish and Game for review and comment. STATE CLEARINGHOUSE This environmental document must be submitted to the State Clearinghouse for review by one or more State agencies (e.g. Cal Trans, California Department of Fish and Game, Department of Housing and Community Development). The public review period shall not be less than 30 days (CEQA Guidelines 15073(a)).. 1101112i/ CITY OF SAN LUIS OsISPO 2 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2002 Q- I 1 ` ATTACHMENT 4 DETERMINATION: On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. X I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made, or the mitigation measures described on an attached sheet(s) have been added and agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant" impact(s) or "potentially significant unless mitigated" impact(s) on the environment, but at least one effect (1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and (2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (1) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (2) have been avoided or mitigated pursuant to that earlier EIR of NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required. October 7,2002 igna a Date Ron Whisenand, Deputy Director of Community Development For:John Mandeville,Community Development Director Printed Name CITY OF SAN LUIS OBISPO 3 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2002 a - �a ATTACHMENT 4 EVALUATION OF ENVIRONMENTAL IMPACTS: 1. A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the analysis in each section. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g. the project falls outside a fault rupture zone). A"No Impact"answer should be explained where it is based on project-specific factors as well as general standards (e.g. the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis). 2. All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts. The explanation of each issue should identify the significance criteria or threshold,if any,used to evaluate each question. 3. "Potentially Significant Impact' is appropriate if there is substantial evidence that an effect is significant. If there are one or more "Potentially Significant Impact" entries when the determination is made,an EIR is required. 4. "Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section 17, "Earlier Analysis," may be cross-referenced). 5. Earlier analysis may be used where, pursuant to the tiering,program EIR, or other CEQA process,an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063 (c) (3) (D) of the California Code of Regulations. Earlier analyses are discussed in Section 17 at the end of the checklist. 6. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g. general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7. Supporting Information Sources: A source list should be attached,and other sources used or individuals contacted should be cited in the discussion. In this case,a brief discussion should identify the following: a) Earlier Analysis Used. Identify and state where they are available for review. b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on earlier analysis. C) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 1.AESTHETICS.

The visual character of the site and its surrounding will not be significantly impacted by the development of a new residence, as there is similar CITY OF SAN LUIS OBISPO 4 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2002 Q- i3 Issues, Discussion and Support. iformation Sources Sources Pot y Potentially Less Than No Signinvant Significant Significant Impact MS/ER #139-02 Issues unless Impact Mitigation 1655 Alrita Street Incorporated development in the immediate vicinity of the project site. The development of one additional single family residence is not likely to create a new substantial source of light or glare, or create overlook issues, if the residence is developed in accordance with required Zoning Ordinance Standards. To ensure adequate review of the new home site at the rear of the existing residence, the Community Development Director has determined that the lot is a "sensitive site" and architectural review will be required for further development of the rear lot. Conclusion The designation of the lot as a "sensitive site," requiring architectural review is appropriate because of the sensitive nature of development in deep lot subdivision situations. The Architectural Review Commission and the Community Development Director routinely review these types of projects and require conditions of approval to insure compatibility of new designs and to insure privacy for occupants of the project and for neighbors. 2.AGRICULTURE RESOURCES. Would theproject: a) Convert Prime Farmland, Unique Farmland,or Farmland of Statewide Importance(Farmland),as shown on the maps pursuant to the Farmland Mapping and Monitoring Program of 14 X the California Resources Agency,to non-agricultural use? b) Conflict with existing zoning for agricultural use or a Williamson Act contract? 10 X c) Involve other changes in the existing environment which,due to their location or nature,could result in conversion of Farmland 12X to non-agricultural use? F Evaluation The site is too small to be considered significant farmland and is currently within a developed residential neighborhood. The Farmland Mapping and Monitoring Program of the California Resources Agency designates this property as Urban Land. There is no Williamson Act contract in effect on the project site. Conclusion There are no known impacts to agricultural resources. 3. AIR QUALITY. Would theproject: a) Violate any air quality standard or contribute substantially to an 12,15, existing or projected air quality violation? 16,30 X b) Conflict with or obstruct implementation of the applicable air 12,15, quality plan? 16, 30 X c) Expose sensitive receptors to substantial pollutant X concentrations? 12, 30 d) Create objectionable odors affecting a substantial number of people? 12 X e) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard 12,15, X (including releasing emissions which exceed qualitative 16, 30 thresholds for ozoneprecursors)? Evaluation The Air Quality Handbook finds that a project that produces 10 pounds a day of emissions will have a significant effect on air quality.The construction of 35 homes results in the production of approximately 10 pounds of emissions per day.The proposed project will ultimately allow the construction of one additional home, therefore it can be assumed that less than Ctry OF SAN LUIS Osispo 5 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2002 Q, - +� ATTACHMENT 4 issues, Discussion and Supporti. iformation Sources Sources Pot y Potentially Less Than No Signu,cant Significant Significant Impact MS/ER#139 02 Issues Unless Impact Mitigation 1655 Alrita Street Incorporated significant air quality impacts will result from construction of a new residence and an access drive. During project construction, however,there will be increased levels of fugitive dust associated with construction and grading activities,as well as,construction emissions associated with heavy-duty construction equipment. The City has addressed these construction related impacts through standards in the Grading Ordinance. Compliance with these standards is monitored during the building permit plan check process and by field inspections conducted by Building Division inspectors. Conclusion The project may create temporary impacts,considered to be less than significant,due to the construction of a new residence. Once completed,the project will not introduce additional air quality impacts to the project vicinity. 4. BIOLOGICAL RESOURCES. Would theproject: a) Have a substantial adverse effect,either directly or indirectly or through habitat modifications,on any species identified as a candidate,sensitive,or special status species in local or regional 12 X plans,policies,or regulations,or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? b) Have a substantial adverse effect,on any riparian habitat or other sensitive natural community identified in local or regional plans,policies,or regulations,or by the California Department 12 X of Fish and Game or U.S.Fish and Wildlife Service? c) Conflict with any local policies or ordinances protecting biological resources,such as a tree preservation policy or 12 X ordinance(e.g.Heritage Trees)? d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors,or impede the use of 12 X wildlife nursery sites? e) Conflict with the provisions of an adopted habitat Conservation Plan,Natural Community Conservation Plan,or other approved 5, 12 X local,regional,or state habitat conservation plan? f) Have a substantial adverse effect on Federally protected wetlands as defined in Section 404 of the Clean Water Act (including,but not limited to,marshes,vernal pools,etc.) 12 X through direct removal,filling,hydrological interruption,or other means? Evaluation a),b) According the Natural Diversity Database of the California Department of Fish and Game,there are no species identified as a candidate,sensitive,or special status species in local or regional plans,policies,or regulations,or by the California Department of Fish and Game or U.S. Fish and Wildlife Service on or near the project site, nor is riparian habitat or other sensitive natural community identified. The City's creek map, which is based on USGS mapping data,does not identify a creek,drainage swale or other waterway on or near the project site. c)No tree removals are proposed at this time. If tree removals are proposed with the development of the rear lot, the issue will be addressed as part of the Architectural Review process, as provided for in the City's Tree Ordinance. d)The property is completely surrounded by urban development and the division of the property and ultimate construction of an expanded driveway and additional residence will not interfere with the movement of any wildlife species or migratory wildlife corridor.

Conclusion The project is not likely to result in any impacts to biological resources. 5.CULTURAL RESOURCES. Would theproject: a) Cause a substantial adverse change in the significance of a historic resource?(See CEQA Guidelines 15064.5) 10, X 21,22 b) Cause a substantial adverse change in the significance of an archaeological resource?(See CEQA Guidelines 15064.5) 21,22 X c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? 11,21 X d) Disturb any human remains,including those interred outside of formal cemeteries? 23 X Evaluation Based on review of the City's Historic Site Map and Land Use Information System, the project is not located on or near a known sensitive archaeological site or historic resource. There are no known paleontological resources or unique geologic features on the project site. The project site is outside of the areas designated on the City's Burial Sensitivity Map as potential burial sites. Conclusion No impacts to cultural resources are known or have been identified. 6. ENERGY AND MINERAL RESOURCES. Would theproject: a) Conflict with adopted energy conservation plans? 6 X b) Use non-renewable resources in a wasteful and inefficient manner? 6, 12 X c) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the 6 X State? Evaluation The project is consistent with the City's Energy Conservation Element that encourages concentrations of residences close to concentrations of employment. The additional dwelling that will likely result from the proposed lot split would be considered an infill project as it would be surrounded by existing urban development, thereby reducing energy impacts that could be created by placing additional housing further from existing development. No known mineral resources exist within the project vicinity. �M CITY OF SAN Luis OBtsPO 7 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2002 a - ►to ATTACHMENT 4 Issues, Discussion and Supporti, (formation Sources Sources Pot 1 Potentially Less Than No Sigm....ant Significant Significant Impact MS/ER#139-02 Issues Unless Impact Mitigation 1655 Alrita Street incorporated Conclusion No impact to energy or mineral resources have been identified. 7.

Landslides or mudflows? 10 X b) Result in substantial soil erosion or the loss of topsoil? 13,30 X c) Be located on a geologic unit or soil that is unstable,or that would become unstable as a result of the project,and potentially result in on or off-site landslides,lateral spreading,subsidence, 13 X liquefaction,or collapse? d) Be located on expansive soil,as defined in Table 18-1-B of the Uniform Building Code(1994),creating substantial risks to life 13 X or property? Evaluation a)San Luis Obispo County,including the City of San Luis Obispo,is located within the Coast Range Geomorphic Province, which extends along the coastline from central California into Oregon. This region is characterized by extensive folding, faulting,and fracturing of variable intensity. In general, the folds and faults of this province comprise the pronounced northwest trending ridge-valley system of the central and northern coast of California. Under the Alquist-Priolo Special Studies Zone Act, the State Geologist is required to delineate appropriately wide special studies zones to encompass all potentially and recently-active fault traces deemed sufficiently active and well-defined as to constitute a potential hazard to structures from surface faulting or fault creep. In San Luis Obispo County,the special Studies Zone includes the San Andreas and Los Osos faults.The edge of this study area extends to the westerly city limit line,near Los Osos Valley Road.According to a recently conducted geology study(source 16), the closest mapped active fault is the Los Osos Fault,which runs in a northwest direction and is about one mile from the City's westerly boundary. Because portions of this fault have displaced sediments within a geologically recent time(the last 10,000 years),portions of the Los Osos fault are considered "active". Other active faults in the region include: the San Andreas, located about 30 miles to the northeast,the Nacimiento, located approximately 12 miles to the northeast,and the San Simeon-Hosgri fault zone, located approximately 12 miles to the west. Although there are no fault lines on the project site or within close proximity, the site is located in an area of"High Seismic Hazards," specifically Seismic Zone 4, which means that future buildings constructed on the site will most likely be subjected to excessive ground shaking in the event of an earthquake. Structures must be designed in compliance with seismic design criteria established in the California Building Code for Seismic Zone 4. To minimize this potential impact, the Uniform Building Code and City Codes require new structures to be built to resist such shaking or to remain standing in an earthquake. b) The project site is substantially landscaped. If development occurs in the future,the City routinely requires landscape plans to be submitted with building permit applications. The installation of landscaping will prevent significant loss of top- soil on the project site. c),d) The Safety Element of the General Plan indicates that the project site has a moderate potential for liquefaction, which is true for most of the City,and the site contains highly expansive soils as defined in Table 18-1-B of the Uniform Building �S CITY OF SAN LUIS OSISPO 8 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2002 a-+-� ATTACHMENT Issues, Discussion and Supportir.- ,formation Sources Sources Pott Potentially Less Than No Signincant Significant Significant Impact MS/ER#139-02 Issues Unless Impact Mitigation 1655 Alrita Street Incorporated Code(1994). A soils engineering report will be required to be submitted as part of the building permit process to insure the integrity of the structures and infrastructure. Conclusion Less than significant impact. 8. HAZARDS AND HAZARDOUS MATERIALS. Would the pr Ject: a) Create a significant hazard to the public or the environment through the routine use,transport or disposal of hazardous 29 X materials? b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the 29 X environment? c) Emit hazardous emissions or handle hazardous or acutely hazardous materials,substances,or waste within one-quarter 29 X mile of an existing or proposed school? d) Expose people or structures to existing sources of hazardous emissions or hazardous or acutely hazardous materials, 29 X substances,or waste? e) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and,as a result,it would create a significant hazard to 12 X the public or the environment? f) For a project located within an airport land use plan,or within two miles of a public airport,would the project result in a safety 27 X hazard for the people residing or working in the project area? g) Impair implementation of,or physically interfere with,the adopted emergency response plan or emergency evacuation 4, 12 X plan? h) Expose people or structures to a significant risk of lose,injury, or death,involving wildland fires, including where wildlands are 4 X adjacent to urbanized areas or where residents are intermixed with wildlands? Evaluation The project does not involve the routine use, transport, or disposal of hazardous materials. The division of land and future construction of a single-family residence would not result in the release of hazardous materials into the environment. The project site is not included on a list of hazardous materials sites compiled pursuant to Government Code § 65962.5. The project site is more than 2 miles north of the San Luis Obispo County Airport, outside the Airport Land Use Plan Area. The project has been reviewed by the Fire Marshall and will not conflict with any emergency response plan or emergency evacuation plan. The Safety Element of the General Plan identifies the site as having a low potential for impacts from wildland fires. Conclusion No impact.

HYDROLOGY AND WATER QUALITY. Would theproject: a) Violate any water quality standards or waste discharge requirements? 12 X b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level(e.g.The production rate of pre-existing 12, 19 X nearby wells would drop to a level which would not support existing land uses for which permits have been granted)? c) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or 12, 19 X provide substantial additional sources of polluted runoff. d) Substantially alter the existing drainage pattern of the site or area in a manner which would result in substantial erosion or 30 X siltation onsite or offsite? e) Substantially alter the existing drainage pattern of the site or area in a manner which would result in substantial flooding 30 X onsite or offsite? f) Place housing within a 100-year flood hazard area as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map 26 X or other flood hazard delineation map? g) Place within a 100-year flood hazard area structures which would impede or redirect flood flows? 26 X h) Otherwise substantially degrade water quality? 12 X Evaluation The applicant will be required to dispose of wastewater to the City's sewer system. The project will be served with water by the City's Utilities Department and will not use or otherwise deplete groundwater resources or interfere with groundwater recharge. The proposed redevelopment of the site will increase the amount of impervious surfaces on the site and may affect the absorption rate, drainage patterns, and the amount and rate of surface runoff. To ensure that potential drainage impacts are minimized to a level of insignificance, redevelopment of the site will be required to be designed to meet all applicable City codes, including City grading and drainage standards. Site drainage will be evaluated with the grading plans as part of the required Architectural Review process. The project design does not substantially alter the existing drainage pattern of the site or area in a manner which would result in substantial flooding on-site or off-site as the site is already partially developed and compliance with City grading and drainage standards would apply to any construction. The project site appears to be out of the 500-year flood zone per the Federal Flood Hazard Boundary or Flood Insurance Rate Map. Therefore, no future structure (i.e. house) on the property would impede or redirect flood flows or occur within a 100- year flood hazard area. Conclusion The project does not have the potential to significantly impact hydrology or water quality. 10. LAND USE AND PLANNING. Would theproject: a) Conflict with applicable land use plan, policy, or regulation of an agency with jurisdiction over the project adopted for the 1, 8 X purpose of avoiding or mitigating an environmental effect? b) Physically divide an established community? 1, 10 X c) Conflict with any applicable habitat conservation plan or natural community conservationplans? 1, 12 X CnY OF SAN LUIS OBIsPo 10 1NrnAL STUDY ENVIRONMENTAL CHECKLIST 2002 ,=� - I ATTACHMENT 4 Issues, Discussion and Supportil formation Sources Sources Pon j Potentially Less Than No Sigm�.,.ant Significant Significant Impact MS/ER#139 02 Issues Unless Impact Mitigation 1655 Alrita Street Incorporated Evaluation The project complies with all provisions of the General Plan Land Use Element. The proposed subdivision would create 2 lots from one existing parcel.The project meets criteria for a categorical exemption from environmental review except that the front lot is only 71 feet deep where 90 feet is the minimum standard. The exceptions do not affect the project's ability to avoid or mitigate an environmental effect. The proposed lots will meet all other subdivision requirements and will be subject to current Zoning Ordinance standards. There is not a habitat or natural community conservation plan adopted for this area, therefore,the project would not conflict with such. Conclusion Less than significant impact.City Council approval is required for minor subdivisions that include exceptions to subdivision standards.Exceptions associated with this subdivision proposal are an issue of neighborhood compatibility,property aesthetics,safety and fire access,all of which are routinely dealt with through the Architectural Review process. 11.NOISE. Would the project result in: a) Exposure of people to or generation of"unacceptable"noise levels as defined by the San Luis Obispo General Plan Noise 3, 18 X Element,or general noise levels in excess of standards established in the Noise Ordinance? b) A substantial temporary,periodic,or permanent increase in X ambient noise levels in the project vicinity above levels existing 30 without the project? c) Exposure of persons to or generation of excessive ground borne X vibration or ground borne noise levels? 3, 18 d) For a project located within an airport land use plan,or within two miles of a public airport or public use airport,would the 27 X project expose people residing or working in the project area to excessive noise levels? Evaluation a) The proposed project itself will not generate unacceptable noise levels, only temporary, short-term increased noise levels during construction as discussed below. The City's Noise Element and Noise Guidebook does not identify Traffic Noise Exposure Calculations for Akita Street as it is a local residential street. At build-out, exterior noise levels are not anticipated to reach the 6013b threshold. Maximum noise exposure for a residence is 45 dB for indoor spaces and 60 dB for outdoor activity areas. b), c) The project will not raise ambient noise levels in the project vicinity substantially. The project will, however,generate noise during grading and construction. These activities are subject to the City's Noise Ordinance to minimize impact to nearby properties. d) The project is not within the Airport Land Use Plan area, therefore, the project will not result in exposure of people to excessive noise levels from aircraft operations. Conclusion Less than significant impact. 12. POPULATION AND HOUSING. Would theproject: a) Induce substantial population growth in an area, either directly CITY OF SAN LUIS OBISPo 11 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2002 CD—W ATTACHMENT 4 Issues, Discussion and Supporti, iformation Sources Sources Pot ✓ Potentially Less Than No Signi.._ant Significant Significant Impact MS/ER#139 02 Issues Unless Impact Mitigation 1655 Alrita Street Incorporated (for example by proposing new homes or businesses) or indirectly (for example, through extension of roads or other 12,30 X infrastructure)? b) Displace substantial numbers of existing housing or people necessitating the construction of replacement housing 30 X elsewhere? Evaluation The Parcel Map would result in the availability of a parcel for construction of a single-family dwelling unit. Such use is consistent with Land Use and Housing Element policies encouraging a variety of housing types, efficient infill development, and compact urban form. The possibility of one additional housing unit does not constitute "substantial population growth. As there are no dwellings on the proposed new parcel, no housing or people would be displaced as a result of the project. Conclusion No impact. 13.PUBLIC SERVICES. Would the project result in substantial adverse physical impacts associated with the provision,or need,of new or physically altered government facilities,the construction of which could cause significant environmental impacts,in order to maintain acceptable service ratios,response times,or other performance objectives for any of the public services: a) Fire protection? 12 X b) Police protection? 12 X c) Schools? 12 X d) Parks? 12 X e) Roads and other transportation infrastructure? 12 X f) Other public facilities? 12 X Evaluation The characteristics of the project do not present situations or conditions that would create potentially significant impacts to services for fire, police, schools, parks, roads or other public facilities. The project has been evaluated by the City's Fire Marshall, Chief Building Official, Public Works Department, Utilities Department, the local school district, and affected utility companies,and no resource deficiencies have been identified. Conclusion Less than significant impact. 14.RECREATION. Would theproject: a) Increase the use of existing neighborhood or regional parks or other recreational facilities such that substantial physical 30 X deterioration of the facility would occur or be accelerated? b) Include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse 30 X physical effect on the environment? Evaluation a), b) One additional home on this property will not create significant impacts to recreation services or facilities in the City. Final approval of the new lot will also be subject to payment of the Park-In-Lieu fee designed to support park acquisition CITY OF SAN LUIS OBISPo 12 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2002 a-�+ ATTACHMENT 4 Issues;Discussion and Support) (formation Sources Sources Pot y Potentially Less nan No Sign..._�nt Significant Significant Impact MS/ER#139-02 Issues Unless Impact Mitigation 1655 Alrita Street Incorporated (Quimby fees)and development. Conclusion Less than significant impact. 15. TRANSPORTATION/TRAFFIC. Would theproject: a) Cause an increase in traffic which is substantial in relation to the existing traffic load and capacity of the street system? 2, 12 X b) Exceed,either individually or cumulatively,a level of service standard established by the county congestion management 2, 12 X agency for designated roads and highways? c) Substantially increase hazards due to design features(e.g. sharp curves or dangerous intersections)or incompatible uses(e.g. 30 X farm equipment)? d) Result in inadequate emergency access? 12, 30 X e) Result in inadequate parking capacity onsite or offsite? 9 X f) Conflict with adopted policies supporting alternative transportation(e.g.bus turnouts,bicycle racks)? 2, 12 X g) Conflict with the San Luis Obispo County Airport Land Use Plan resulting in substantial safety risks from hazards,noise,or a 27 X change in air trafficpatterns? Evaluation a), b) Traffic generation associated with an additional single-family lot will not significantly increase traffic, nor exceed the level of service standards established by the City's General Plan for nearby streets and highways. A typical single-family residential use generates 10 trips/day which would be an insignificant increase not affecting LOS. c) There are no hazards which the project would be subject to or create. d) The project complies with the Fire Department's requirements for emergency access and any new dwelling will be required to be equipped with fire sprinklers per existing City code. e) City parking standards will apply to any new construction proposed on the new parcel. f) The project does not conflict with alternative transportation policies in that the project does not impede any existing or proposed bike baths, transit stops,etc. g) The project is not within the Airport Land Use Plan area, therefore, there is no conflict with the Plan that would result in substantial safety risks from hazards,noise or a change in air traffic patterns. Conclusion No impact. 16.UTILITIES AND SERVICE SYSTEMS. Would the ro'ect: a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? 12 X b) Require or result in the construction or expansion of new water treatment,wastewater treatment,or storm drainage facilities,the construction of which could cause significant environmental 12 X effects? M CrrY OF SAN LUIS OBIsPO 13 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2002 a-aa ITTAr.NMENT Issues; Discussion and Support, iformation Sources Sources Poi y Potentially Less Than No Sign...-ant Significant Significant Impact MS/ER#139-02 Issues Unless Impact Mitigation 1655 Alrita Street Incorporated c) Have sufficient water supplies available to serve the project from existing entitlements and resources,or are new and 12 X expanded water resources needed? d) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to 12 X the provider's existing commitment? e) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? 24 X f) Comply with federal,state,and local statutes and regulations related to solid waste? 24 X Evaluation a), d) The City wastewater treatment plant has adequate capacity to serve this development, and the existing sewers in the vicinity have sufficient capacity to serve the development. Impact fees are collected at the time building permits are issued to pay for capacity at the City's Water Reclamation Facility. The fees are set at a level intended to offset the potential impacts of the project. Wastewater impact fees are associated with water usage, so determination of applicable impact fees will be made at the building permit stage. b) This project has been reviewed by the Utilities Department staff. Comments note that the project is subject to water impact fees which were adopted to ensure that new development pays its fair share of the cost of constructing the water supply,treatment and distribution facilities that will be necessary to serve it. c) The City has adopted Water Allocation Regulations to ensure that increased water use by new development and land use changes do not jeopardize adequate water service to current and new customers. Compliance with the provisions of the Water Allocation Regulations and the water impact fee program is adequate to mitigate the effects of increased water demand. A water allocation is required for any new residence on the new parcel. The City currently has water to allocate,and does so on a"first-come, first-served"basis. Water is allocated at the time building permits are issued and the Water Impact Fee is paid. e),f) Background research for the Integrated Waste Management Act of 1989(AB939)shows that Californians dispose of roughly 2,500 pounds of waste per month. Over 90%of this waste goes to landfills,posing a threat to groundwater,air quality,and public health. Cold Canyon landfill is projected to reach its capacity by 2018. The Act requires each city and county in California to reduce the flow of materials to landfills by 50%(from 1989 levels)by 2000. To help reduce the waste stream generated by this project,consistent with the City's Source Reduction and Recycling Element,recycling facilities must be accommodated on the project site and a solid waste reduction plan for recycling discarded construction materials must be submitted with the building permit application. The new residence will be subject to subscribing to the City's trash collection service which provides receptacles for recycling and green waste materials consistent with the Source Reduction and Recycling Element. Construction of a new residence on the proposed parcel will require demolition of the existing garage. This will trigger compliance with the City's construction debris recycling ordinance. This will be determined upon submittal of a demolition permit application. Compliance with this ordinance will require the applicant to prepare a plan to show how significant amounts of construction debris will be diverted from the landfill. The ordinance also requires reporting on compliance with the approved plan,which is verified by area recycling companies and through the provision of receipts for recycled materials.

As discussed in the biological section of this study, there are no species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations,or by the California Department of Fish and Game or U.S. Fish and Wildlife Service on or near the project site, nor is riparian habitat or other sensitive natural community identified. With regard to historical resources, the project is not located on or near a known sensitive archaeological site or historic resource. There are no known paleontological resources or unique geologic features on the project site,and the project site is outside of the areas designated on the City's Burial Sensitivity Map as potential burial sites. b) Does the project have impacts that are individually limited,but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of the past projects, X the effects of other current projects,and the effects of probable futureprojects) The proposed project's cumulative impacts are insignificant for the same reasons discussed in this study for project-specific impacts. c) Does the project have environmental effects which will cause substantial adverse effects on human beings,either directly or X indirectly? There are no environmental effects identified that would cause substantial adverse effects on human beings. While construction noise may affect persons in the vicinity of the property once construction of infrastructure,or a residence begins, it would last only for a relatively short period of time, and the City's noise thresholds must be met which have been determined to be acceptable noise levels. 18.EARLIER ANALYSES. Earlier analysis may be used where, pursuant to the tiering, program EIR, or other CEQA process, one or more effects have been adequately analyzed in an earlier EIR or Negative Declaration. Section 15063 (c) (3) (D). In this case a discussion should identify the following items: a) Earlier analysis used. Identify earlier analyses and state where they are available for review. N/A b) Impacts adequately addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. N/A c) Mitigation measures. For effects that are "Less than Significant with Mitigation Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions of the project.

(2002 Series) _ A RESOLUTION OF THE COUNCIL OF THE CITY OF SAN LUIS OBISPO APPROVING THE TENTATIVE MAP AND NEGATIVE DECLARATION FOR A MINOR SUBDIVISION LOCATED AT 1655 ALRITA STREET MS/ER 139-02 (SLO 02-0210) WHEREAS, the City Council conducted a public hearing on November, 11th 2002 and has considered testimony of interested parties and the evaluation and recommendation of staff; and WHEREAS, the City Council has considered the draft Negative Declaration of environmental impact as prepared by staff; and WHEREAS, minor subdivisions with requests for exceptions require City Council review and approval; BE IT RESOLVED,by the City Council of the City of San Luis Obispo as follows: SECTION 1. Environmental Review. The City Council finds and determines that the project's Negative Declaration adequately addresses the potential significant environmental impacts of the proposed project, and reflects the independent judgment of the City Council. The Council hereby adopts said Negative Declaration. SECTION 2. Findings. That this Council, after consideration of a request to subdivide one lot into four lots with an exception to the subdivision ordinance; staff recommendations, public testimony, and reports thereof, makes the following findings: Minor Subdivision 1. As conditioned, the design of the tentative map and proposed Limprovements are consistent with the general plan and its policies that call for compact urban form and a variety of housing types compatible with the surrounding neighborhood. This is because the proposed new lot is an infill lot, located within an existing rear yard of a developed residence. Furthermore, the property is surrounded by urban development. 2. As conditioned, the site is physically suited for the type and density of development allowed in the R-1 zone, since the proposed lot meets all size standards as required within the R-1 district and project conditions will require architectural review for new development. 3. The design of the tentative map and the proposed improvements are not likely to cause serious health problems, substantial environmental damage or substantially and unavoidably injure fish or wildlife or their habitat since the project does not involve significant tree removal, it does not interfere with creeks or wetlands, and the site is surrounded by urban development. 4. The design of the subdivision will not conflict with easements for access through (or use a-aq ATTACHMENT Resolution No. (2002 Series) MS/ER 139-02(Strong Minor Subdivision) Page 2 of property within) the proposed subdivision since all adjacent properties are accessed independently and the new proposed lot, as conditioned, will gain access from a shared driveway with the existing property. Exceptions to Subdivision Standards forAccessway Setback(flag lot standards) 5. The property to be divided is of such size or shape, or is affected by such topographic conditions, that it is impossible, impractical or undesirable, in the particular case, to conform to the strict application of the regulations codified in the Subdivision Ordinance. Approval of this subdivision in accordance with the lot depth standards would require demolition of, or moving an existing residence. General Plan policy discourages the demolition of sound housing and there is no public benefit to require the existing house to be moved; and 6. The cost to the subdivider of strict or literal compliance with the regulations is not the sole reason for granting the modification. It is City policy to conserve existing housing and prevent displacement of occupants; and 7. As conditioned, the modification will not be detrimental to the public health, safety and welfare, or be injurious to other properties in the vicinity since the modification will only result in a reduced lot depth of approximately 19 feet. If the lot depth were measured from the proposed flag lot access driveway this lot would meet all standards of the Subdivision Ordinance; and 8. Granting the modification is in accord with the intent and purposes of these regulations, and is consistent with the general plan and with all applicable specific plans or other plans of the city since it does not grant special privileges or modify allowable land uses within the existing R-1 district. SECTION 3. Approval. The request for approval of the minor subdivision (MS 139-02) to allow creation of two lots from one existing lot with an exception to the Subdivision Ordinance, Section 16.36.230 flag lot driveway width and subdivision lot depth requirements, for property at 1655 Alrita, is hereby approved subject to the following conditions: Conditions: 1. Approval of this Tentative Tract Map shall be valid for two years after its effective date. At the end of the period, the approval shall expire and become null and void unless an extension of time is granted pursuant to a written request received prior to the expiration date. 2. The Tract map shall be subject to additional fees for park or recreation purposes (QUIMBY Act) as required by City Ordinance. ATTACHMENT � Resolution No. (2002 Series) MS/ER 139-02(Strong Minor Subdivision) Page 3 3. The granting of this entitlement shall apply to the property located at 1655 Alrita Street (APN 004-683-016)regardless of owner. 4. A final map drawn in substantial conformance with the approved tentative map, and in compliance with all conditions set forth herein, shall be submitted for review and approval in accordance with the Subdivision Map Act and the City's Subdivision Ordinance. 5. Each residence shall maintain a minimum of 800 square feet of quality private open space. The height of each residence shall not exceed 25 feet, as measured from average natural grade to the highest point on the structure. 6. All trees shall be protected and preserved on the site unless otherwise approved for removal by the City Arborist. Removal of any tree on site shall require a City tree removal permit and mitigation to consist of on-site replanting. Street trees are required to the satisfaction of the City Arborist. 7. The new parcel "2" as shown on the Tentative Parcel Map shall be considered "Sensitive" and construction on the new parcels shall be subject to architectural review to consider neighborhood compatibility. 8. Provisions must be made to accept and convey offsite drainage to an adequate point of disposal to the satisfaction of the Public Works Director and Building Official. 9. All newly graded surfaces shall be protected from soil erosion with City approved temporary erosion control methods or approved permanent landscaping. 10. Each property shall share a common driveway approach with Alrita Street, and each residence shall maintain a ten-foot setback from the driveway edge of pavement. The maximum driveway width serving each residence shall not exceed 12 feet. Driveway shall be designed to allow vehicles to exit individual properties in a forward position with a minimum amount of maneuvering. 11. Each property shall maintain on-site parking consistent with the Zoning Ordinance and the City Parking and Driveway standards. On site Parking shall consist of two parking spaces per residence. 12. A common address identification sign located at the intersection of the driveway and Foothill Boulevard shall identify each of the residential lots. Individual lots shall be identified with an address sign at the driveway intersection of each private lot and the main access driveway. The design of the address signs shall be approved by the C � ATTACHMENT Resolution No. (2002 Series) MS/ER 139-02(Strong Minor Subdivision) Page 4 Community Development Department. 13.

Mayor Settle, Councilmembers, I ask the council to NOT accept this proposed subdivision for the following reasons: 1. A Negative Declaration should not be allowed. This parcel is on a hillside and there is currently a drainage issue existing in relation to the homes around and particularly below the existing parcel. The hillsides above Johnson Ave are also known to have many natural underground springs. If infill is allowed as this project before you is proposed,( and springs do exist in this subdivision), this could exacerbate the current drainage problem. An EIR would properly address the issues. 2. There are no other flag lots in the neighborhood. If two houses are allowed to be built as proposed by allowing a flag lot, how do you address the parking problems? The city housing ordinance currently allows 5 unrelated people to live in a R-1 house. If 5 people are allowed to live in each of these houses there could be 10 cars. Where is the parking to accommodate for these cars, and the friends and relatives that visit these 10 people? This property has an existing house and garage on it. The Realtor selling it is advertising this as a lot for sale not a home? It is being marketed as a builders/developers dream for investment/speculation. This is an established pristine family neighborhood. Allowing this subdivision acceptation of a lot split, could be opening up a can of worms for more aoceptions. To be fair to one, you must be fair to all of the others? The realtor is asking for acceptions to subdivide this lot. This means that the lot does not conform to current allowed building codes as it is. Allowing these exceptions would severely compromise the charm and character of this established pristine neighborhood. Thank you for your cooperation. Sincerely, eCOUNCIL ❑ CDD DIR �!

November 12, 2002 City of San Luis Obispo OU ATTN: City Council RECEIVED 990 Palm Street San Luis Obispo, CA 93401 'J� r Z U ' Re: MS/ER 139-02 (Strong, 1655 Ahita) I SLO CITY CLERK Dear Council Members: I currently live in an area which is zoned R-2. The proximity of the housing units allows the conversations of others to be heard clearly. I don't just mean that voices are audible, 1 mean that words are easily distinguishable. In the R-1 neighborhood that we are considering tonight that is not the case. Sufficient front, rear and side set-backs are in place to provide privacy for families living there. Yes, voices can be heard, but conversations cannot. Dividing medium-sized R-1 properties in order to build additional housing units may have already occurred in other parts of this city. Those are the areas where noise complaints are the rule rather than the exception. This area, however, has retained its single-family character. The staff report describes this proposed property division and subsequent development as "infill." According to the definition adopted in the city's General Plan, "infill" refers to the development of a vacant parcel, not to creating additional lots by dividing existing developed ones. Thus, the term"infill" is a misnomer for this proposed action. The staff report, also, states that the property division and subsequent development are consistent with the neighborhood. That statement discounts two factors, placement of the proposed dwelling behind the existing one and the absence of garages. 1. Page 2-7 of the report shows one lot off of Johnson Avenue which was sub-divided into four lots with two houses built directly behind two other houses—this is the only occurrence in this area where one house has been built behind another off of the same street. Johnson is a thoroughfare and consists of commercial as well as residential properties. It is not indicative of the neighborhood we are considering here tonight. 2. Removing the existing 2-car garage from proposed Parcel #1 —and providing no replacement for it—is a significant deviation from other properties in the neighborhood. Without seeing the plan for the proposed Parcel#2, it is impossible to determine if it, too, will not be consistent with the established neighborhood. (I walked about five blocks in the area around the 1655 Ahita property and looked at each house. Of 48 properties, 46 had 2-car garages and the other two had oversized carports capable of holding two cars. This includes the flag lots off Johnson; all four of these houses had 2-car garages.) V i The staff report mentioned that the proposed development of the site will "increase the amount . of impervious surfaces on the site and may affect the absorption rate, drainage patterns and rate of surface runoff" What was not mentioned was the topography of this proposed rear parcel and that by building a structure at the rear of the existing lot, drainage of rainwater into the back yards of Bahia Court and Flora Street properties would be aggravated. It appears that both proposed lots will need a depth variance. The minimum lot depth as stated in the code is 90 feet. The depth of the proposed front lot is 71 feet. It appears to me that the depth of the proposed rear lot is smaller. (Both proposed lots exceed the width requirement, the front being 90 - 100 feet and the rear being almost 130 feet.) The staff report states that the dimensions for the rear lot are 64 feet wide by130 feet deep. When I looked at the parcel map, it seemed to me that these dimensions had been transposed. The report further states, "Typically, a flag lot's frontage is measured from the access drive." So then I spent several hours looking at the codes and zoning regulations on the city's web site and I could find no reference to measuring a flag lot's frontage from the access drive. I did find the statement that"each lot shall front on a street" and several references to methods for measuring lot width along the public street frontage and lot depth perpendicular to the public street frontage. The only exception listed was for lots within condominium subdivisions. I also found a definition for the term"street" which states a street is an avenue, boulevard, etc., but is not an alley or path. This made me think that a street is not an access drive either. The city code contains lot size, set-back, parking and other standards for various zones of the city. In this R-1 neighborhood, houses meet or exceed those standards; waivers are not needed. Also, a house must have a 2-car garage to be consistent with this neighborhood. It is not a wealthy neighborhood, but it is a nice one. It would be a shame to set the precedent of relaxing those standards in this or any other area of the city. Dividing the property this way eliminates the garage which goes with the house, and no replacement garage is provided. This is a flaw in the pian being shown to you tonight. By approving it you will be saying that this is acceptable. The house at 1655 Alrita is currently vacant, the heir lives out of state, and the property is for sale. It is interesting to note that the real estate agency has listed it under the heading"Lots and Acreage," not under"Residences." According to the real estate agent, an offer has been accepted, and the buyer has a plan for developing the property. Why isn't that plan included in this application so that you can see the final result of the requested action? You are being asked to decide one element of a development plan without knowing what that plan involves. Several items are to be left to the Architectural Review Committee. Approving this request tonight may tie their hands. Will further waivers be requested for situations that might have been avoided if full disclosure had been provided at the outset of the project? Unintended consequences may result from hasty approval of this request.
