FROM: Nicole Horvitz, Assistant Planner Alley APPROVED: Debbie Pedro, AICP, Planning Director RECOMMENDATION: That the Planning Commission: Review the staff report and proposed ordinance amendments in attachment 1, consider any revisions, and forward a recommendation to the City Council. BACKGROUND: On July 15, 2010 the City Council voted 4-1 (Warshawsky-No) to adopt the Fast Track Guide for New Residences, an updated version of the former Guidelines for Residential Design and Land Use (Design Guidelines), and directed staff to prepare the necessary amendments to the Town's Zoning and Site Development Ordnances. Councilmember Warshawsky was concerned that the Fast Track Guide could be used to delay a project in a similar manner as the former Design Guidelines did. For example, neighbors opposed to a new residence could hold up the approval because the project does not meet all the goals of the Fast Track Guide, but does comply with the Town's ordinances and policies. With the adoption of the document, the Fast Track Guide and checklist must be incorporated into the Municipal Code in Section 10-2.1305.1 (Fast Track Process). In addition, multiple code sections need to be amended given that they reference the former Design Guidelines, which were repealed by City Council in 2001. DISCUSSION The proposed amendments would incorporate the Fast Track Guide and checklist as a part of the Fast Track Process in Section 10-2.1305.1. Staff Report to the Planning Commission September 2, 2010 Page 2 of 2 10-2.1305.1 Fast-track process: Add to subsection (a) (3)— There is no substantive neighborhood opposition to the project ("substantive" is not based on the number of neighbors objecting); however, new residences that score 14 or fewer points on the Town's Fast Track Guide for New Residences (Fast Track Guide) checklist and meet the other requirements of this subsection 10-2.1305.1(a), shall be eligible for the Fast Track process, regardless of neighborhood opposition. Add to subsection (b) — • For a new residence project, the Planning Director or designee shall determine the project's eligibility for the Fast Track process using the Fast Track Guide Checklist. Only projects that score 14 points or less shall be eligible for the Fast Track process. The Fast Track Guide Checklist, or a project's conformance with the Fast Track Guide Checklist, shall not provide the basis for the Site Development Authority's approval, conditional approval, or disapproval of a project • Add to subsection (c) - A new residence which scores 15 points or greater on the Fast Track Guide checklist. The term "Design Guidelines" will be removed from the following six (6) code sections: • 10 -2.1305.1 -Fast Track Process • 10-1.502 (e) -Development Area • 10-1.503(e) - Floor Area • 10-1.504 (f) -Height • 10-1.505 (e)- Setback Lines • 10-2.1305 (d) & (e)- Applications -Actions and Hearings The complete sections of the ordinances with proposed amendments (highlighted in red) are included in attachment 1. CEQA REVIEW The proposed ordinance amendments are exempt from California Environmental Quality Act (CEQA) pursuant to "general exemptions" described in Section 15061 (b) (3) of the CEQA Guidelines, since the ordinance amendments would not have any significant effects on the environment.

BACKGROUND On May 14, 2009, the City Council unanimously voted to establish an Ad Hoc Subcommittee to review and update the former Guidelines for Residential Design and Land Use ("Design Guidelines") as an educational tool for Town residents. The Subcommittee followed a two-step process to update the Design Guidelines. First, the content of the document including the goals, philosophies and guidelines were reviewed and revised to ensure that they were relevant and appropriate. Then, the document was updated with an improved format, a checklist was incorporated, and the document renamed the Fast Track Guide for New Residences. At their June 3, 2010 meeting, the Planning Commission voted 4-1 (Collins, Clow, Harpootlian, Partridge -YES; Abraham -NO) to recommend adoption of the Fast Track Guide with several modifications. The Commission's recommended changes are highlighted in red in the draft Fast Track Guide. (Attachment 2) DISCUSSION The purpose of the Fast Track Guide is to assist those who are planning to build a new home to understand the basic philosophy behind the Zoning and Site Development Ordinances and the General Plan. The Fast Track Guide includes a combination of design solutions that are encouraged along with standards that are required. It is not intended that a new residence design meet the letter of each development guideline. The recommended guidelines are meant to provide greater clarity regarding acceptable design solutions. A checklist that accompanies the Fast Track Guide will be used to determine how closely a proposed new residence complies with the required and the recommended guidelines. Staff Report to the City Council Fast Track Guide for New Residences July 15, 2010 Page 2 of 3 How will the Fast Track Guide be used in relation to the existing site development process? The checklist works on a negative point system. Each development guideline has an established point value between 1 to 5 (1=recommended, 5=very important). Projects that do not comply with a particular guideline will receive the applicable points. Since each property is different and unique, if an item is not applicable for a specific site, it will not count against the project. A new residence that scores 14 points or less is eligible for a Fast Track hearing. A project that scores between 15 to 21 points may be redesigned or forwarded to the Planning Commission. A project that scores 22 points or greater must be reviewed by the Planning Commission. How will the Fast Track Guide be used in relation to existing_ development standards in the Municipal Code? The Fast Track Guide and checklist will be used solely to determine whether a project would be eligible for the Fast Track Review process pursuant to Section 10-2.1305.1 of the Los Altos Hills Municipal Code. Since many of guidelines within the document represent good design principles rather than quantifiable standards, it could be construed as arbitrary when required to be implemented. To avoiduncertainty and confusion, the Site Development Authority should limit review of new residence projects to elements of the proposed development which are specifically addressed by provisions in the Town's General Plan, Zoning and Site Development Codes, and Town policies adopted by the Council. Related Code Amendments Currently, the Town's Municipal Code still contains references to the Design Guidelines which was repealed in 2001. As a result, the following six (6) code sections will need to be amended: • 10 -2.1305.1 -Fast Track Process a 10-2.1305 (d) & (e)- Applications -Actions and Hearings • 10-1.503(e) - Floor Area c 10-1.505 (e)- Setback Lines • 10-1.502 (e) -Development Area • 10-1.504 (f) -Height Staff recommends removal of the term "Design Guidelines" from all the sections mentioned above, as they are no longer applicable. If the City Council decides to adopt the proposed Fast Track Guide, Section 10-2.1305.1 of the Site Development Code (Fast Track Process) should be amended to include a provision that the Fast Track Guide and checklist will be used solely to determine a project's eligibility for the Fast Track process. Council is not being asked to adopt any amendments to the Municipal Code at this time but provide direction to staff on the preparation of these amendments. • Staff Report to the City Council Fast Track Guide for New Residences July 15, 2010 Page 3 of 3 Public Comments A Town wide postcard notice for the proposed Fast Track Guide for New Residences was mailed on May 17, 2010. At the June 3 Planning Commission meeting, three residents spoke in favor of the project and suggested changes to improve the document. Additional information regarding this project is included in the June 3, 2010 Planning Commission staff report and draft meeting minutes. (Attachments 3 and 4) CEQA STATUS The proposed Fast Track Guide for New Residences and Ordinance Amendments are exempt from California Environmental Quality Act (CEQA) pursuant to Section 15378(b)(2). FISCAL IMPACT There is no fiscal impact with this recommendation. ATTACHMENTS 1. Resolution Adopting the Fast Track Guide for New Residences 2. Draft Fast Track Guide for New Residences 3.

Once a rural agricultural area, the community has become one of the premier residential areas in Silicon Valley. Over the years, the population has grown and land use patterns have changed. The farmhouses, cattle ranches, and orchards of the past have become today's private homes, riding stables, and vineyards. The community has gradually urbanized over time but still retains a semi -rural atmosphere, with large lots and expanses of open space, as envisioned by the Town's founders. The Town is characterized by rolling hills, valleys, creeks, woods, and wildlife. Many properties have sweeping views of the San Francisco Bay, Santa Clara Valley, and the coastal mountains to the west. Most well established properties fit into the immediate environment and harmoniously blend with the overall neighborhood. The Town's Zoning Ordinances and General Plan require that every effort be made to preserve the Town's semi -rural character, natural atmosphere, and rustic appearance. Thus, a newcomer who buys an undeveloped lot with the intent of building an entirely new home is faced with a special challenge, and a resident who wishes to rebuild an existing residence must be careful to see these requirements are met. The purpose of this guide and the checklist is to help those who are planning to build new homes to understand the basic philosophy behind the Zoning Ordinances and the General Plan. Such an understanding will help them arrive, more rapidly, at a home design which will be consistent with the demands of the environment, and also assist in avoiding the delay and costs of redesigns. Building of homes in the Town is regulated by the Town's Zoning Ordinances and the General Plan. This handbook is meant to familiarize the homeowner and/or designer with the spirit of these legal documents and is not meant to replace them. If this guide appears in any detail to conflict with them, the Zoning Ordinances and the General Plan take precedence. If you need any additional clarification of these guidelines, the Town staff will always be ready and pleased to provide it. 3 1 P a g e Things to Keep in Mind When You Use This Guide 1. This guide has been developed to be consistent with the Town's ordinances, policies, and regulations. Ordinances and polices are modified from time to time, so it is advisable to check with the Town Planning Department to determine whether there have been any significant changes since the guidelines were published. 2. The Fast Track checklist that accompanies this document will be used to determine how closely a proposed new residence complies with the development philosophy of the Town. A new residence project that scores 14 points or less is eligible for a Fast Track hearing. A project that scores between 15 to 21 points may be forwarded to the Planning Commission. A project that scores 22 points or greater must be reviewed by the Planning Commission. 3. This guide is intended to set the framework for appropriate design, but not inhibit creativity in design. If your plans substantially deviate from the guide there must be adequate justification. 4. Every lot in the Town of Los Altos Hills is unique. Not all aspects of this guide will be applicable to every lot. 5. If you have not yet purchased a home site, and have a particular style of house in mind, you should look for a lot that will accommodate your chosen style. If you have already acquired a lot, be sure to design a home appropriate for that specific lot, taking into consideration these guidelines. 6. On a visible lot, both the good and bad points of the design of a home tend to show up more obviously than on a more secluded lot. Therefore, it is important when planning a home on an exposed lot, to observe this guidebook more rigorously. 7. A pre -application meeting is extremely helpful to the prospective home owner and design professional. The planning staff can help point out the characteristics of the site and alert the owner to important factors which may not be obvious. Such factors may include: on and off site views, configuration of the lot, privacy issues, existing or potential future pathway requirements, and potential for the requirement of an open space easement. The planning staff can also advise you as to whether the project would be subject to Fast Track or Planning Commission review. 8. In addition to the required public notice procedure, it is also important to perform neighborhood outreach. Often times it is possible to work with your neighbors to come to a design solution without compromising your intended design, or stifling your own creativity. Establishing good relations with your future neighbors can often make the entire planning review process smoother. 4Page Some of the Town's Key Development Regulations Basements: Under certain conditions, basements may not count as floor area. Conservation A portion of land reserve for the purpose of protection the natural vegetation, terrain, Easement: watercourses, and wildlife. A conservation easement is voluntarily created and is perpetual in duration. Fencing: Fencing is restricted in height and openness on certain areas of a lot. Green All new residences must achieve a minimum rating under either Build It Green or LEED for Homes rating Building: systems. Grading: No grading is allowed within 10 feet of the property line. Height: Maximum permitted building height is 27 feet measured from natural or finished grade, whichever is lower. The maximum height from the building's lowest point to the highest roof elevation is 35 feet. Min. Lot Size: The minimum size of a lot required for home construction increases with the slope of the land. It is one net acre if the slope is 10% or less, about 1.5 acres for lots with slopes of 25%, and about 2 acres for lots with 33% slopes. Open Space Dedication of open space easements may be required where appropriate as a condition of approval for new Easement: development. Each parcel will be evaluated on a case-by-case basis during the site development review process to determine whether an open space easement should be required, based on the extent of steep slopes (generally in excess of 30%), the presence of heritage oak trees, and/or creek corridors. Other considerations include the size of the proposed open space easement, its contiguity with existing open space easements, and whether the property is located within an Open Space Conservation Area. Parking: All residences must have at least four off-street parking spaces. 5 1 P a g e Pathways: If the Town's Master Pathway Plan calls for a path on the property, the path is required to be constructed and complete when the new residence is completed. Where driveways cross a path, they must have a non -slip surface. (Title 10, Chapter 2, Article 6 of the Los Altos Hills Municipal Code) Setbacks: Minimum required setbacks are as follows: front yard -40 feet from road right of way or access easement, side and rear yard -30 feet from property line, road right of way or access easement. Slope Density: The Town has created slope density requirements as a way to equalize the intensity of development on both steep and flat lots. In general, the steeper the lot, the larger it needs to be to hold the same amount of development as a flatter lot with equal impact. When implementing this "slope density" concept, the Town considers two aspects of a building site: the floor area of a building and the amount of land covered by development. The Town imposes a maximum floor area (MFA) and a maximum development area (MDA). Two characteristics of the lot affect these numbers: the average slope (steepness) and the net area (acreage) of the site. These limits are designed to keep the overall impact of developing steeper lots no greater than the impact of the traditional one (1) acre flat lots. Stories: Three (3) story building facades are strongly discouraged, and two (2) story houses may not be permitted on hilltops and ridges. Trees: The Town has a Tree Ordinance that protects heritage oak trees. 6 1 P a g e Lot Size tot We 1 Net Awe 2 Net Acres � $ MDA=15,000 MDA=30,000 Sbpe=1-10% MFA=6,000 MFA=12,000 4, z MDA=8,843 MDA=17,670 Sbpe=20% MFA=5,000 MFA=8,661 MDA=5,670 MDA=7,500 Sbpe=40% MFA=3,570 MFA=5,000 Stories: Three (3) story building facades are strongly discouraged, and two (2) story houses may not be permitted on hilltops and ridges.

Siting can mitigate bulk. Whenever possible, place the house on the lot so that it is framed by the land or existing vegetation. 1. Increasing the setbacks may help mitigate mass and bulk of structures.

Architectural details can mitigate size and bulk. 1. Longer roof eaves and rakes are encouraged for shade. 2. Roof slopes should be consistent and complementary with the topography of the site. I House should be keyed/cut into slopes to reduce fill. 4. Trellises are encouraged for shade instead of solid roofs (on patios, balconies, and breezeways) to minimize bulk. 5. The use of architectural devices such as verandas, balconies, arcades, trellises, building materials, etc ... are encouraged to soften the building bulk. 6. Vertical and horizontal articulation of building facades should be used to avoid long, uninterrupted exterior walls. Appropriate scale and proportions should be incorporated into the design to avoid improper balance of the structure. 201 Page Desirab e less Desirable Desirable Less Desirable licipa r- ecticr 7C2 (c) Goal III: Design Your House to Minimize the Appearance of Bulk Philosophy C. Exterior materials and colors should blend your house into its surroundings. Utilize colors which occur naturally in the landscape of your site. Darker or natural colors blend with surroundings. Roofs should be a dark color if possible and have a variety of shades of that color. A mixture of materials can create interest and detail. Wood and stone can help to soften the appearance of stucco and blend it with the natural setting. The use of texture and well designed detail added to wall surfaces can distract from large blank wall areas and minimize their perceived impact. 1. For exterior building materials, darker or natural colors are encouraged. Energy efficient "cool roofs" are available in darker colors. 211 Page Goal III: Design Your House to Minimize the Appearance of Bulk Philosophy D. Building to less than the maximum height can decrease the perception of bulk. t A- yzql+ 4 1. Two story walls which increase perception of mass can be mitigated by introducing detail, setting back the second story, lowering the second story plate height, or using a combination of one and two story elements in the design. 221 Page 1. 1.

Basements can reduce bulk by putting portions of the house underground. 1. On a sloping lot, basements below a two story home should not be daylighted, to avoid the appearance of a three story facade. 2. The appearance of a stacked three story facade should be avoided. When building on a sloping lot, stepping with the hillside is encouraged.

Staff decisions are appealed to the Planning Commission, Planning Commission Section 10-1.1002 decisions are appealed to the Council. Average Slope Average slope describes the steepness of a lot and is important for determining how much Los Altos Hills Municipal Code development will be allowed. Lots with average slope exceeding 10% have greater restrictions Section 10-1.202 regarding amount of development permitted. Basement A basement is space partly or wholly underground. Under some circumstances it may not be Los Altos /fills Municipal Code counted as floor area. Section 10-1.202 Building Circle For a new lot to be created, it must be able to contain within its net area a circle of 160' in diameter. Los Altos Hills Municipal Code This is called the building circle. The ultimate building site does not necessarily have to be in the Section 9-1.603 (a) circle, but there must be a buildable site in the building circle that is accessible by a driveway. Conditional Development Permit A conditional development permit (CDP) is a permit with special conditions to mitigate problems on Los Altos Hills Municipal Code substandard or severely constrained lots granted by the Planning Commission or the City Council. Section 10-1.007 (3) Among those lots that require CDP's are those that have a lot unit factor (LUF) less than 0.5 and some lots constrained by habitation setback for geologic hazard or noise. Conditional Use Permit A conditional use permit (CUP) is a permit granted by the Planning Commission or City Council for a Los Altos Hills Municipal Code use other than residential use. Other uses, as specified in the codes, may be permitted with Section 10-1.1007 (1) conditions. Development Area Development area is the total floor area plus the total area of land covered by structures and Los Altos Hills Municipal code hardscape not included in floor area. Areas exempted from being counted as development area are Section 10-1.502 described in code section 10-1.502. The maximum development area (MDA) is the largest amount of development area allowed on the lot. It is a function of the net acreage and average slope (steepness) of the site. Some lots may be so constrained that they may never be able to use their full MDA. Findings 301 Page Findings are a set of circumstances which will make the granting of special privilege such as a variance, a CUP, or a CDP acceptable under the law. Floor Area Floor area is the sum of the area of all floors including the garage and any attic (or similar space) Los Altos Hills Municipal Code which exceeds seven feet. In addition, any areas over 17 feet from floor to ceiling count double. Section 10-1.503 Some basements are exempt from being counted as floor area (see definition of basement). The maximum floor area (MFA) allowed depends on both the net acreage and slope of the lot. Because floor area is part of development area, the greater the floor area the less development area available outside. Hardscape Hardscape includes all artificially produced impervious and semi -permeable surfaces, such as concrete, asphalt, pools, sports courts, permeable pavers, permeable concrete, grasscrete pavers, artificial turf, and wooden decks. Height of a Structure The height of a structure is the distance from natural or finished grade (whichever is lower) to the Los Altos Hills Municipal Code top of the structure. The maximum height allowed for any vertical section of a structure is 27 feet, Section 10-1.504 and 35 feet measured between the lowest natural grade elevation of the structure along the building line and the highest elevation of the roof of the structure, including appurtenances. An increased vertical building height of up to 32' may be allowed with increased setbacks. Heritage Oak A heritage oak is an oak tree with a diameter of 12" or more when measured at least four feet Los Altos Hills Municipal Code above the root crown. Section 12-2.101 Human Habitation Setback A human habitation setback (HHS) is an area of a lot on which no habitable structure may be placed because of a seismic hazard. Such setbacks are typically 25 feet on either side of a fault line. Lot Unit A lot unit is the minimum acreage required for a lot with a given slope. A three acre parcel will contain three lot units if its slope is 10% or less, two lot units if its slope is 25%, but only one lot with slope of 42%. Lot Unit Factor The lot unit factor (LUF) is the number of lot units in a given parcel. Some lots with a LUF less than Los Altos Hills Municipal Code one were created early in the Town's history. These lots are considered non -conforming and their Section 10-1.202 development is restricted accordingly. Lots with LUF less than one may not be created today.

Non -Conforming Lot Los Altos Hills Municipal Code An existing lot that does not meet the Town's current standards is considered non -conforming. Section 10-1.1007 (3) Among the reasons a lot may non -conforming are: a LUF less than one or a lot unable to hold a 160' diameter building circle. Off Road Paths Los Altos A major recreation amenity of the Town is our off road pathway system. Paths usually run along Hills Municipal Code Section 10-1.202 easements located on the property lines of many parcels. On Road Paths Pathways that run along or within a road right of way are call on -road paths. Los Altos Hills Municipal Code Section 10-1.202 Open Space Easement Open space easements exist to protect the land and such natural features as slopes over 30%, oak tree coverage, and creeks. There may be additional restrictions depending on the nature of the easement. Ridgeline Los Altos Hills Municipal Code Lots deemed to be on a ridgeline may be subject to design restrictions aimed at making the Section 10-2.702 (b) ICUOUS. structures less cons p Road Right of Way The full width of the road is the road right of way. Usually only a portion of it is paved. Secondary Unit A secondary unit is an attached or detached dwelling unit which has facilities for eating, sleeping, Los Altos Hills Municipal Code Section 10-1.702 (1) cooking, and sanitation located on the same parcel as the primary unit. A secondary unit may not exceed 1,000 square feet in floor area. No more than one secondary unit is allowed per parcel. One net acre is required. Setback Los Altos Hills Municipal Code The setback is a line defining an area adjacent to the property line in which no structures may be y Section 10-1.505 built. There is a 30 foot setback for the rear and side property p perty lines and a 40 foot setback for the front. Site Analysis Site analysis is a process by which a homeowner meets with staff before development plans have progressed substantially to learn about potential constraints, design considerations, and general guidelines in designing a home. Variance A variance is an exemption to a law or standard granted to resolve a difficulty or inequity (not of the Los Altos Hills Municipal Code Section 10- 1.1007 (2) applicant's own making) which may result from exceptional circumstances of a property. 321Page A.
