An application that is consistent with Town plans and-policies, and has submitted all necessary reports and information can be processed with .minimal delay. • The HDS&G establish a framework for appropriate design, standards and minimum and/or maximum requirements. However, stricter standards may be required to avoid potential impacts and to achieve the goals and objectives of the .HDS&G. ® Applicants are encouraged to creatively meet he goals and objectives of the HDS&G. ® The .illustrations provided in the HDS&G are. schematic and .meant to show the intent of a standard or guideline. ® .Not every site can be .developed at the maximum density or intensity allowed by the Zoning Ordinance. .Some sites cannot accommodate atwo-story ,home or accessory uses such as swimming pools, tennis courts, etc. ® It is beneficial to inventory the site's natural, .physical properties (such as slope distribution and geology). A site plan and design ..program should be developed only after the Least Restrictive Development Area (LRDA) has been identified based on a site specific constraints analysis. This approach will assist in designing ..,projects that avoid or fit in with the site's natural constraints. ® It makes for good relations with your future neighbors if you meet with them beforehand to discuss any special concerns they may have prior to siting and designing the house, landscaping, or making any significant site improvements. ® Since the Town's goals, .policies, and regulations may change from time to time, it is advisable to check with the Town's Community Development Department for any changes.

Vision Statement The Town of Los Gatos is a beautiful and special ,place nestled at the '.base of the Santa Cruz Mountains. The mountains provide an exceptional backdrop, providing the Town with a beautiful, natural environment. Tt is the vision of Los Gatos that this natural asset'be preserved by .insuring that any development in hillside areas: • maintains the existing open, wooded, rural character; • is in harmony with the natural setting; • conserves landforms and other features of the natural landscape; • preserves wildlife habitat and movement corridors; and • protects :and preserves viewsheds and the ridgelines of the .mountains. ~. Overvacew The .Hillside Development Standards & Guidelines (HDS&G) are intended to .acknowledge that: ® The rural, natural open space character of the hillsides is an important component of the Town's character and charm. ® The hillsides are geologically and. enVironmentaily sensitive areas. Development in the hillsides has the potential to affect, and'be effected by, the environment. Awareness of a site's natural constraints will result in development that is sensitive to the environment, incorporates safeguards to maximize public safety, and minimize changes to the visual. equality of the hillsides. Property owners should have the opportunity to build, expand, or remodel However, such changes must, recognize and respect the constraints associated with hillside development. C. ~®al The overall goal of the Hillside Development Standards and Guidelines is to work hand in hand with the Town's discretionary development review process to achieve design excellence that fosters sustainable development and preserves the natural environment. `Page ~ i Town of Lc Hillside Are .LEGEND Areas Subject to the Hillside Development. ..Standards and Guidelines .

This is a critical step in he overall planning and design of projects in the hillsides. When all constrained areas have been identified. and mapped, the remaining .area(s) will be designated as the ~~LEAST RESTRICTIVE DEVELOPMENT AREA" (LRDA). These are the areas most appropriate for development. To ensure -that new development is sensitive to the goal .and objectives of the Hillside Development Standards and Guidelines and respects the existing site constraints, the following elements shall be mapped by appropriate .professionals and taken .into consideration when .determining. a site's LRDA: ® Topography, with emphasis on slopes over 30% ® Vegetation such. as individual trees, groupings ofi trees and shrubs, habitat types ® Drainage courses and riparian corridors . ® Septic. systems ® Geologic .constraints including landslides and active -fault traces ® Wildlife habitats and movement corridors ® Visibility from ofF site ® Areas of severe fire danger ® Solar orientation and .prevailing wind ,patterns ® Signifiicant Ridgelines Many of the above topics are covered in more. detail in Chapter TLB. and Chapter ITI. The accurate determination of the LRDA early in the planning process could avoid delays once an application has been submitted.

Maximum Allowable Development The Town of Los Gatos controls the amount of development that is allowed by limiting density and intensity of development -the ..minimum land area required for each house -and by limiting -- the maximum floor area of each house. Tn Los Gatos, .limiting the floor area or size of a House is important for several reasons: • Large houses are more visible and therefore create greater adverse visual impacts. • Large houses cover more land area,. therefore requiring more disruption of the natural landscape and ecosystems. • Large houses create more impervious surface area, which can .increase runofF and cause drainage, landslide, and flooding problems. • Large houses consume a greater amount of resources, both to construct and to maintain. Iwaximum allowed gross floor area. The maximum allowable gross floor area Refer to the Town's for homes subject to the Hillside. Development Standards and Guidelines is zoning determined -using a floor area .ratio (FAR) adjusted for slope as provided in Table Regulations 1, below. However, achieving. the maximum floor area allowed is .not guaranteed `~&° due to individual site constraints. The priority is to comply with :the standards and guidelines rather than designing to the FAR. The FAR is a numerical guide and achieving the allowable quare footage is not a goal. Greater weight shall. be given to issues, including but not limited to, .height, building .mass and scale, visual .impacts, grading and compatibility.

Design for snstainability. Sustainability -and the conservation of natural. resources are important issues to Los Gatos residents. Sustainability refers to the use of natural resources in a manner that insures their continued availability to future generations. The term "green building" is often used to relate sustainability to development. Green building addresses a broad range of techniques to reduce the consumption of .natural resources .during : construction and over the lifetime of a'home. These include designing structures to be energy water efficient, utilizing building materials that reduce resource consumption and improve indoor air quality, and taking maximum advantage of renewable energy resources. Refer to Appendix B for additional information on green building. Appendix B, Green .Building Strategies and .Materials, contains design strategies that maximize the use of renewable energy resources for heating, cooling and lighting, additional strategies . that conserve energy and water, a list of building materials that reduce the consumption of nonrenewable. resources .and improve air quality, and a list of various sources for "green building" information and their web sites. The. following design guidelines are aimed at maximizing energy efficiency and reducing --- consumption of resources. ~tandLar~s: None. ' ~n.delnest 1. 'The design of each house should show evidence to the satisfaction of the deciding body that a significant effort has been made-towards incorporating energy-conservation and water saving techniques above and beyond the minimum ..requirements of Title 24. 2. All. homes over 3,500 square feet should incorporate a variety of green building . strategies and materials (see Appendix:B). Mornes .less than 3,500 square feet are also ; encouraged to incorporate additional energy and resource saving features. 3. Homes should be designed and ocated to-take maximum advantage of passive solar heating (space and water), natural cooling and lighting. Houses. should be designed to maximize the benefits of sun and wind as follows: a. Orient the .house and arrange doors and windows to take advantage of prevailing ummer winds for natural ventilation and cooling (also see Appendix B). b. Orient the house and the most used 'living areas to take advantage of passive solar' heating.

Subdivisions may be processed under the provisions of the Town of Los Gatos .Zoning Ordinance as a standard subdivision or in conjunction with a Planned Development overlay zone. The maximum density of new subdivisions in hillside areas is determined by the use of a slope .density formula that diminishes residential densities as the slope of the natural terrain increases. The purpose of the PD overlay zone, as it relates to hillside areas, is to encourage the appropriate location of residential units in the least restrictive 'Refer to the Towns development areas of the site. The intent is to significantly reduce the amount of zoning grading, roads, :and other alterations to the .existing environment, to minimize the ordinance visual impact. of the. development, and to retain the maximum amount of - continuous open space in its .natural state.
