To guide physical development consistent with the social, economic, aesthetic, and equity values of the City.
Urban design describes the physical features that define the character or image of a street, neighborhood, community, or the City as a whole. Urban design is the visual and sensory relationship between people and the built and natural environment. The urban environment includes buildings and streets, and the natural environment includes features such as shorelines, canyons, mesas, and parks as they shape and are incorporated into the urban framework. Citywide urban design recommendations are necessary to ensure that the buildings continue to contribute to the qualities that distinguish the City of San Diego as a unique living environment.
Each community member and visitor may perceive San Diego’s aesthetic character differently, although there are several basic design elements that are commonly recognized by all. San Diego’s distinctive character results from its unparalleled natural setting, including beaches, bays, hills, canyons and mesas that allow the evolution of geographically distinct neighborhoods. The network of small human-scaled canyons creates a natural open space system that extends through many parts of the City and is unparalleled in other American cities. The topography and San Diego’s year-round climate are ideal for outdoor pedestrian activity of all kinds.
Construction of Balboa Park and Mission Bay Park modified the natural environment but created unique public and civic spaces that are still much used and admired. Many of San Diego’s older neighborhoods built prior to World War II capitalized on the City’s natural features and temperate climate. The open porches on early twentieth-century craftsman style homes and the bungalow courts focused on common open space. Much of the post war development did not respond to San Diego’s climate or natural conditions. Porches were

eliminated and pedestrian connections deemphasized. The older commercial corridors in San Diego are more suitable to San Diego’s pleasant climate with walkable shopping districts Downtown and in North Park.
As San Diego becomes more urbanized, there is a need to address urban form and design through policies aimed at respecting our natural environment, preserving open space systems, targeting new growth into compact villages and maximizing public spaces for people to enjoy the outdoors and connect with neighbors, family and friends. As the availability of vacant land becomes more limited, designing infill development and redevelopment that builds upon our existing communities becomes increasingly important. A compact, efficient, and environmentally sensitive pattern of development consistent with the City of Villages strategy becomes increasingly important as the City continues to grow. Future development should also accommodate and support existing and planned transit service.
While certain aspects of design may be subjective, there are design principles that can be implemented to promote a positive identity across various communities. To effectively implement a citywide urban design strategy requires the establishment of objective urban design guidance. Objective design guidelines should be measurable, verifiable, and involve no personal or subjective judgment. The Urban Design Element provides high-level guidance to establish an overall urban design strategy.
There are several urban design principles relating to the existing City form and achieving a compact and environmentally sensitive pattern of development envisioned in the City of Villages strategy. These principles are identified below to provide a framework for the goals of the Urban Design Element:

where a high level of activity already exists or can be realized; and
The Urban Design Element incorporates the “core values” from the Strategic Framework Element (2002) (Appendix A, Section SF-1). The core values related to urban form include:
The physical, social, and cultural diversity of our City and its neighborhoods.
The Urban Design Element addresses urban form and design through policies aimed at respecting our natural environment, preserving open space systems and targeting new growth into compact villages. Urban form and how it functions becomes increasingly important as changes in density and intensity occur over time, as San Diego evolves. The urban design principles established in this element are intended to help achieve an identity for the City as a whole while encompassing its physical, social and cultural diversity. A higher overall quality of urban design is another fundamental goal. Urban design applies at multiple levels from citywide to community to neighborhood and ultimately to individual projects.
Urban design is a process to foster quality in the built and natural environment as the City changes Urban Design Element policies help support and implement land use and transportation decisions, encourage economic revitalization, and improve the quality of life in San Diego. Ultimately, the General Plan’s Urban Design Element influences the implementation of all elements of the General Plan and community plans as it establishes goals and policies for the pattern and scale of development and the character of the built environment. The urban design policies will be implemented through objective design criteria, including area-specific community plan policies and the Land Development Code.

The City’s urban form is loosely based upon a naturally connected system of open space, characterized by valleys, waterways, canyons and mesas. Remaining natural features should be preserved to the greatest extent possible. The City of Villages strategy provides guidance to determine where and how new growth should occur. The strategy seeks to target growth in village areas at core locations within communities adjacent to community facilities, existing and future transit facilities, and supportive land uses.
There are several urban design issues relating to existing City form and the compact and environmentally sensitive pattern of development envisioned in the City of Villages strategy. These issues provide a framework for the goals of the Urban Design Element. The policies that support these goals are intended to contribute to the qualities that distinguish San Diego as a unique living environment and highlight the value of our open space resources as part of the overall built environment. Another key element of the policies contained in this element is the importance of building upon our existing communities. This includes implementation of the City of Villages growth strategy that seeks to direct growth into areas where a high level of activity and transit service exist.
The design of buildings play a significant role in reducing crime and the perception of risk to one’s safety. Crime Prevention Through Environmental Design (CPTED) concepts provide recommendations on designing safer environments. Many of the CPTED concepts are complementary to the City of Villages approach, since strategies to increase opportunities for surveillance are

similar to those used to accomplish greater walkability. The CPTED policies can change over time and are a resource used in design.
The following policies are intended to guide all citywide commercial, industrial, institutional and residential and mixed-use developments. Overall, the policies call for the City’s urban form to be defined and shaped by the natural environment, to improve upon what is best about San Diego’s neighborhoods, and to foster the creation of convenient, and where appropriate, well-designed village centers where commercial and residential development are concentrated.
San Diego has little remaining land that is vacant and available for development. Most of the remaining open space is designated for permanent open space or agricultural use and will not be urbanized. As San Diego continues to evolve, new development should not seek to imitate existing development, but should be sympathetic to the scale, form, proportion and materials of the more distinctive existing development, particularly in the historic neighborhoods. As the City grows and matures, new approaches to design will be fostered, so this element does not recommend particular architectural styles. The overall citywide urban design policies are intended to achieve quality design over time, to reinforce a sense of community, and respect the City’s historic diversity.
UD-A.1 Preserve and protect natural landforms and features.
a. Protect the integrity of community plan designated open spaces (see also Conservation Element, Policy CE-B.1).
b. Continue to implement the Multiple Species Conservation Program to conserve San Diego’s natural environment and create a linked open space system. Preserve and enhance remaining naturally occurring features such as wetlands, riparian zones, canyons, and ridge lines.
UD-A.2 Use open space and landscape to define and link communities.
a. Link villages, public attractions, canyons, open space and other destinations together by connecting them with trail systems, bikeways, landscaped boulevards, formalized parks, and/or natural open space, as appropriate.
b. Preserve and encourage preservation of physical connectivity and access to open space.

Development Adjacent to Natural Features and Park Lands
UD-A.3 Design development adjacent to natural features in a sensitive manner to highlight and complement the natural environment in areas designated for development.
a. Integrate development on hillside parcels with the natural environment to preserve and enhance views, and protect areas of unique topography.
b. Minimize grading to maintain the natural topography, while contouring any landform alterations to blend into the natural terrain.
c. Utilize variable lot sizes, clustered housing, stepped-back facades, split-level units or other alternatives to slab foundations to minimize the amount of grading.
d. Consider terraced homes, stepped down with the slope for better integration with the topography to minimize grading in sensitive slope areas.
e. Utilize a clustered development pattern, single-story structures or single-story roof elements, or roofs sloped toward the open space system or natural features, to ensure that the visibility of new developments from natural features and open space areas are minimized.
f. Provide increased setbacks from canyon rims or open space areas to ensure that the visibility of new development is minimized.
g. Screen development adjacent to natural features as appropriate so that development does not appear visually intrusive, or interfere with the experience within the open space system. The provision of enhanced landscaping adjacent to natural features could be used to soften the appearance of or buffer development from the natural features.
h. Use building and landscape materials that blend with and do not create visual or other conflicts with the natural environment in instances where new buildings abut natural areas. This guideline must be balanced with a need to clear natural plants for fire protection to ensure public safety in some areas.
i. Ensure that the visibility of new development from natural features and open space areas is minimized to preserve the landforms and ridgelines that provide a natural backdrop to the open space systems. For example, development should not be visible from canyon trails at the point the trail is located nearest to proposed development. Lines-of-sight from trails or the open space system could be used to determine compliance with this policy.
j. Design and site buildings to permit visual and physical access to the natural features from the public right-of-way.
k. Encourage location of entrances and windows in development adjacent to open space to overlook the natural features.
l. Protect views from public roadways and parklands to natural canyons, resource areas, and scenic vistas.
m. Preserve views and view corridors along and/or into waterfront areas from the public right-of-way by decreasing the heights of buildings as they approach the shoreline, where possible.
n. Provide public pedestrian, bicycle, and equestrian access paths to scenic viewpoints, parklands, and where consistent with resource protection, in natural resource open space areas.
o. Provide special consideration to the sensitive environmental design of roadways that traverse natural open space systems to ensure an integrated aesthetic design that respects open space resources. This could include the use of alternative materials such as "quiet pavement" in noise sensitive locations, and bridge or roadway designs that respect the natural environment.
p. Design structures to be ignition and fire-resistant in fire prone areas or at-risk areas as appropriate. Incorporate fire-resistant exterior building materials and architectural design features to minimize the risk of structure damage or loss due to wildfires.
UD-A.4 Use sustainable building methods in accordance with the sustainable development policies in the Conservation Element.
UD-A.5 Encourage adaptive reuse of buildings into new vibrant uses.
UD-A.6 Support the integration of civic and public recreational uses, such as libraries and recreation centers, into the ground floor and non-residential areas of mixed-use development to foster walkable, well-connected villages with a strong sense of place.
UD-A.7 Design buildings that contribute to San Diego’s needs for homes, jobs, services, amenities, and public spaces while establishing a positive sense of community identity.
a. Relate building design to San Diego’s unique climate and topography.
b. Encourage designs that are sensitive to the scale, form, rhythm, proportions, and materials and create transitions between older and newer buildings.
c. Provide architectural features that establish and define a building’s appeal and contribute to placemaking within the community.
d. Encourage the use of materials and finishes that reinforce a sense of quality and permanence.
e. Design buildings to provide design variation that avoid blank walls fronting streets, paths, parks, and public spaces. This would include not only building walls, but fencing.
f. Design buildings frontages to add interest to the streetscape and enhance the pedestrian experience. For example, walls could protrude, recess, or change in color, height or texture to provide visual interest.
g. Design building wall planes to have shadow relief, where pop-outs, offsetting planes, overhangs and recessed doorways are used to provide visual interest at the pedestrian level.
h. Design rear elevations of buildings to be as well-detailed and visually interesting as the front elevation, if they will be visible from a public right-of-way or accessible public place or street.
i. Acknowledge the positive aspects of nearby existing buildings by incorporating compatible features in new developments.
j. Maximize natural ventilation, sunlight, and views.
k. Provide convenient, safe, well-marked, and attractive pedestrian connections from the public street to building entrances.
l. Design roofs to be visually appealing when visible from public vantage points and public rights-of-way.
UD-A.8 Create street frontages with architectural and landscape interest to provide visual appeal to the streetscape and enhance the pedestrian experience.
a. Locate buildings on the site so that they reinforce street frontages.
b. Relate buildings to existing and planned adjacent uses.
c. Ensure that building entries are prominent, visible, and well-located.
d. Maintain existing setback patterns, except where community plans call for a change to the existing pattern.
e. Minimize the visual impact of parking structures, surface parking and parking entrances to the pedestrian and street façades.
⬚ figure
New development can integrate design elements that reflect a sense of place or history.
UD-A.9 Respect the context of historic streets, landmarks, and areas that give a community a sense of place or history. A survey may be done to identify “conservation areas” that retain original community character in sufficient quantity and quality but typically do not meet designation criteria as an individual historical resource or as a contributor to a historical district.
a. Create objective design criteria to be used for new development, so that a neighborhood’s historic character is complemented within the conservation areas where appropriate (see also Historical Preservation Element, Policy HP-A.2).
b. Review the redevelopment of property within conservation areas to maintain important aspects of the surviving community character that have been identified as characteristics of a neighborhood that could be preserved.
⬚ figure
Thoughtful landscape materials can provide multiple benefits that range from improving aesthetic appeal to supporting environmental goals.
UD-A.10 Landscape materials and design should enhance structures, create and define public and private spaces, and provide shade, aesthetic appeal, and environmental benefits.
a. Maximize the planting of new trees, street trees and other plants for their shading, air quality, and livability benefits (see also Conservation Element, Policies CE-A.11, CE-A.12, and Section J).
b. Use water conservation through the use of drought-tolerant landscape, porous materials, and reclaimed water where available.
c. Use landscape to support storm water management goals for filtration, percolation and erosion control.
d. Use landscape to provide unique identities within neighborhoods, villages and other developed areas.
e. Landscape materials and design should complement and build upon the existing character of the neighborhood.
f. Design landscape bordering the pedestrian network with new elements, such as a new plant form or material, at a scale and intervals appropriate to the site. This is not intended to discourage a uniform street tree or landscape theme, but to add interest to the streetscape and enhance the pedestrian experience.
g. Establish or maintain tree-lined residential and commercial streets. Neighborhoods and commercial corridors in the City that contain tree-lined streets present a streetscape that creates a distinctive character.
h. Shade paved areas, especially parking lots.
i. Demarcate public, semi-public/private, and private spaces clearly through the use of landscape, walls, fences, gates, pavement treatment, signs, and other methods to denote boundaries and/or buffers.
j. Use landscaped walkways to direct people to proper entrances and away from private areas.
k. Reduce barriers to views or light by selecting appropriate tree types, pruning thick hedges, and large overhanging tree canopies.
l. Utilize landscape adjacent to natural features to soften the visual appearance of a development and provide a natural buffer between the development and open space areas.
UD-A.11 Incorporate existing and proposed transit stops or stations into project design (see also Mobility Element).
⬚ figure
a. Provide attractively designed transit stops and stations that are adjacent to active uses, recognizable by the public, and reflect desired neighborhood character (see also Land Use Element).
b. Design safe, attractive, accessible, lighted, and convenient pedestrian connections from transit stops and stations to building entrances and street network (see also Land Use Element).
c. Provide generous rights-of-way for transit, transit stops or stations.
d. Locate buildings along transit corridors to allow convenient and direct access to transit stops/stations.
Streets

Structured Parking
UD-A.13 Encourage the use of underground or above-ground parking structures, rather than surface parking lots, to reduce land area devoted to parking (see also Mobility Element).
a. Design safe, functional, and aesthetically pleasing parking structures.
b. Design structures to be of a height and mass that are compatible with the surrounding area.
c. Use building materials, detailing, and landscape that complement the surrounding neighborhood.
d. Provide well-defined, dedicated pedestrian entrances.
e. Use appropriate screening mechanisms to screen views of parked vehicles from pedestrian areas, and headlights from adjacent buildings.
f. Pursue development of parking structures that are wrapped on their exterior with other uses to conceal the parking structure and create an active streetscape. Where ground floor commercial is proposed, provide a tall, largely transparent ground floor along pedestrian active streets.
g. Encourage the use of attendants, gates, natural lighting, or surveillance equipment in parking structures to promote safety and security.
Surface Parking
UD-A.14 Reduce the amount and visual impact of surface parking lots, as well as the oversupply of parking to provide area for more productive uses (see also Mobility Element).
a. Encourage placement of parking along the rear and sides of street-oriented buildings.
b. Avoid blank walls facing onto parking lots by promoting treatments that use colors, materials, landscape, selective openings or other means of creating interest. For example, the building should protrude, recess, or change in color, height or texture to reduce blank facades.
c. Design clear and attractive pedestrian paseos/pathways and signs that link parking and destinations.
d. Locate pedestrian pathways in areas where vehicular access is limited.
e. Avoid large areas of uninterrupted parking especially adjacent to community public view sheds.
f. Build multiple small parking lots in lieu of one large lot.
g. Retrofit existing expansive parking lots with street trees, landscape, pedestrian paths, and new building placement.
h. Promote the use of pervious surface materials to reduce runoff and infiltrate storm water.
i. Use trees and other landscape to provide shade, screening, and filtering of storm water runoff in parking lots (see also Conservation Element, Policy CE-A.12).
j. Design surface parking lots to allow for potential redevelopment to more intensive uses. For example, through redevelopment, well-placed parking lot aisles could become internal project streets that provide access to future parking structures and mixed land uses.

a. Integrate signage into project design.
b. Include pedestrian-oriented signs to acquaint users to various aspects of a development. Place signs to direct vehicular and pedestrian circulation.
c. Post signs to provide directions and rules of conduct where appropriate behavior control is necessary.
d. Design signs to minimize negative visual impacts.
e. Address community-specific signage issues in community plans, where needed.
Wireless Facilities
UD-A.17 Minimize the visual impact of wireless facilities.
a. Conceal wireless facilities in existing structures when possible, otherwise use camouflage and screening techniques to hide or blend them into the surrounding area.
b. Design facilities to be aesthetically pleasing and respectful of the neighborhood context.
c. Conceal mechanical equipment and devices associated with wireless facilities in underground vaults or unobtrusive structures.
Utilities
UD-A.18 Minimize the visual and functional impact of utility systems and equipment on streets, sidewalks, and the public realm.
a. Convert overhead utility wires and poles, and overhead structures such as those associated with supplying electric, communication, community antenna television, or similar service to underground.
b. Design and locate public and private utility infrastructure, such as phone, cable and communications boxes, transformers, meters, fuel ports, back-flow preventors, ventilation grilles, grease interceptors, irrigation valves, and any similar elements, to be integrated into adjacent development and as inconspicuous as possible. To minimize obstructions, elements in the sidewalk and public right of way should be located in below grade vaults or building recesses that do not encroach on the right of way (to the maximum extent permitted by codes). If located in a landscaped setback, they should be as far from the sidewalk as possible, clustered and integrated into the landscape design, and screened from public view with plant and/or fencelike elements.
c. Traffic operational features such as streetlights, traffic signals, control boxes, street signs and similar facilities should be located and consolidated on poles, to minimize clutter, improve safety, and maximize public pedestrian access, especially at intersections and sidewalk ramps. Other street utilities such as storm drains and vaults should be carefully located to afford proper placement of the vertical elements.
General Urban Design
UD-A.19 Incorporate Crime Prevention Through Environmental Design (CPTED) measures, as necessary, to reduce incidences of fear and crime, and design safer environments.
a. Design projects to encourage visible space and “eyes on the street” security that will serve as a means to discourage and deter crime through the location of physical features, activities and people to maximize visibility.
b. Define clear boundaries between public, semi-public/private, and private spaces.
c. Promote regulations, programs, and practices that result in the proper maintenance of the measures employed for CPTED surveillance, access control, and territoriality.
d. Consider pedestrian scale lighting and indirect techniques to provide adequate security but not glare and flood-light conditions.

The City of Villages strategy identifies a village as a mixed-use center of a community where residential, commercial, employment, and civic uses are present. The intent is that a high quality of urban design will achieve the maximum possible integration of uses and activities connected to the surrounding community fabric and the transit system. Villages will be compact and walkable, with inviting streets and public spaces for community events. Villages will serve as focal points for public gatherings as a result of their outstanding public spaces. In addition to compact residences and retail establishments, villages will contain public spaces that include plazas, public art, cultural amenities, transit centers, enhanced streetscapes, urban trailheads, parks and pocket parks. Publicly-oriented buildings including civic buildings and monuments, public facilities and services, and social services will also contribute to villages as activity centers.
The Land Use and Community Planning Element identifies six categories of villages and mixed-use locations : Regional Center (Downtown), Subregional Employment Areas, Urban Village Centers, Neighborhood Village Centers, Community Village Centers, and Transit Corridors. The policies contained in this section are intended to address the physical integration of uses, provision of a variety of housing types, significant public spaces, and public facilities within a pedestrian environment for all village types. The intent is to create villages that are pedestrian in scale, accessible by diverse multi-modal means, and varied with uses and activities that serve local daily needs.
Village development will occur, in part, through the development and redevelopment of shopping centers. The following policies address key, overall urban design principles for village development, and allow for community plans to provide more specific guidance tailored to each location. Appropriate design will help make these villages true centers of neighborhood activity, rather than just renovated shopping centers.
Commercial corridors are important areas that link neighborhoods together and in many cases, cross community boundaries. The commercial corridors can provide convenient local shopping destinations and space for small businesses to take root. Some commercial corridors are transit corridors that are served with higher frequency transit service, some are designed with a pedestrian-friendly “main street” appearance, and others have a more auto-dominated “strip commercial” design, which currently are often typified by parking located between the front of the building and the street, auto-oriented signs, and minimal landscape.
The policies in this section are intended to offer guidance on how to enhance commercial corridors to achieve the City of Villages goals of creating walkable communities and encouraging transit use with a variety of land uses. The design policies also apply to commercial corridors not identified as transit corridors, with the goal of redesigning these commercial corridors so they enhance the community and are attractive to pedestrians, transit riders, and bicyclists, in addition to drivers.
Commercial centers outside of villages, as well as employment centers, and other types of activity centers should also be designed in accordance with many of the same design policies that apply to village and commercial areas (see also Land Use Element).
San Diego is the first city on the West Coast to implement a Main Street Program. It is affiliated with a nationally recognized economic development approach that focuses on revitalizing the commercial components of downtowns and neighborhood districts in an effort to promote small business development. These programs traditionally use historic preservation and grassroots-based economic development. Efforts at improving and maintaining “main streets” in San Diego provide small businesses with a competitive edge against “big box” retailers and shopping malls.
The City works with Main Street communities to renovate store fronts, plan and coordinate major streetscape improvement and public arts projects, create redevelopment areas to attract investors, and develop marketing plans to attract customers and businesses. North Park, the City’s pilot project, was implemented in 1996 and has shown signs of renewal. Other main street projects in progress include Ocean Beach and Mission Hills.

a. Establish build-to lines to frame and define village center public space and pedestrian streets.
b. Ensure public spaces are easily accessible and open to the public. The mechanisms used to provide the public space will vary as appropriate and could include, but are not limited to: land dedications, joint use agreements, and public access easements. Public space areas may include reasonable hours of use restrictions, demarcation of private and publicly accessible areas, and other signage to communicate public access rights, responsibilities and limitations.
c. Encourage provision of public space in the earliest possible phase of development, as determined by the public’s ability to use and access the space.

In conjunction with the General Urban Design Goals, the following policies are intended to provide further guidance for achieving high-quality residential design. New development can contribute to the beauty, vitality, and functionality of a neighborhood. Development should contribute to the creation of a sense of place and promote a positive and inclusive community identity.
San Diego’s distinctive neighborhoods are a great asset to the City. Some neighborhoods date back to the early days of San Diego’s history and a few are still emerging, but each has elements that set it apart from the others and establish its identity. Many of San Diego’s neighborhoods are the product of small incremental parcelizations and development over a long period of time. Neighborhood character is defined in part by certain physical qualities that repeat throughout neighborhoods, such as landscape and massing of buildings, colors, and materials. The character of a neighborhood or community is also defined by factors including topography and natural features, street layout and streetscape, and landmarks and civic land uses.
Residential housing types include single-home detached homes and multiple family home development, including small-lot rowhomes, townhomes, duplex and triplex homes, and a wide variety of apartment and condominium homes. While densities, unit mix, and design parameters will vary based on individual community plans, there are overall policies that are applicable citywide.
The residential design policies are intended to foster the development of high quality homes that meet the needs of San Diego’s population and that become an integrated part of the larger inclusive neighborhood and community. These policies strive to encourage a coherent image of the City as a whole. These policies will be implemented through objective design criteria.
UD-C.1 Recognize that the quality of a neighborhood is linked to the overall quality of the built environment. Projects should not be viewed singularly, but viewed as part of the larger neighborhood or community plan area in which they are located for design continuity and compatibility.
a. Design new construction to respect the pedestrian orientation of neighborhoods.

San Diego has many unique residential neighborhoods.
b. Provide innovative designs for a variety of housing types to meet the needs of the population.
c. Consider appropriate transitions between areas designated in a community plan for higher-density and lower-density. Consider design factors such as building bulk and mass, existing points of ingress/egress, and the potential for shadow casting.
UD-C.2 Achieve a mix of housing types within developments (see also Land Use and Community Planning Element, and Housing Element).
a. Incorporate a variety of home types in multi-home projects.
b. Incorporate a variety of housing types in single-home neighborhoods that are consistent with the building bulk and mass.
c. Provide transitions of scale between areas designated in a community plan for higher-density and lower-density.
d. Identify sites for revitalization and additional housing opportunities in neighborhoods.
Subdivisions
UD-C.3 Design subdivisions to support walkability and be compatible with the existing lot pattern established within neighborhoods.
Residential Street Frontages
UD-C.4 Create street frontages with building and landscape interest that promote walkability.
a. Locate buildings on the site in order to reinforce street frontages.
b. Relate buildings to existing and planned adjacent uses.
c. Provide ground level entries and ensure that building entries are prominent and visible.
d. Maintain existing setback patterns, except where community plans call for redevelopment to change the existing pattern.
e. Locate transparent features such as porches, stoops, balconies, and windows facing the street to promote a sense of community.
f. Encourage side- and rear-loaded garages. Where not possible, reduce the prominence of the garage through architectural features and varying planes.
g. Minimize the number of curb-cuts along residential streets.
Neighborhood Streets
UD-C.5 Design or retrofit streets to improve walkability, strengthen connectivity, and enhance community identity.
a. Design or retrofit street systems to achieve high levels of connectivity within the neighborhood street network that link individual subdivisions/projects to each other and the community.
b. Avoid closed loop subdivisions and extensive cul-de-sac systems, except where the street layout is dictated by the topography or the need to avoid sensitive environmental resources.
c. Design open ended cul-de-sacs to accommodate visibility and pedestrian connectivity, when development of cul-de-sacs is necessary.
d. Emphasize the provision of high quality pedestrian and bikeway connections to transit stops/stations, village centers, and local schools.
e. Design new streets and consider traffic calming where necessary, to reduce neighborhood speeding (see also Mobility Element).
f. Enhance community gateways to demonstrate neighborhood pride and delineate boundaries.
g. Clarify neighborhood roadway intersections through the use of special paving and landscape.
h. Develop a hierarchy of walkways that delineate village pathways and link to regional trails.
i. Discourage use of walls, gates and other barriers that separate residential neighborhoods from the surrounding community and commercial areas.
j. Encourage design features that integrate new development into the surrounding community.
UD-C.6 Utilize alleys to provide improved and alternative pedestrian access to sites, including consideration of a promenade or paseo design for alleys with enhanced landscaping, and residential units or uses that face the alleys to activate them as alternative pedestrian streets. This could provide an alternative function for alleys that is non-vehicular, but still provides linkages to other sites and uses and adds to a neighborhood's connectivity.
UD-C.7 Work with community groups and property owners to ensure adequate street maintenance, public landscape maintenance, law enforcement, code enforcement, and litter and graffiti control to maintain safe and attractive neighborhoods

The design of our employment areas is a critical element of our City's built environment. It is important to provide pleasant working environments, and for employment centers at the edge of residential neighborhoods and open space systems to be sensitively designed. This may be achieved by applying architectural and site planning guidelines to employment centers. In addition to encouraging office and industrial development to be well designed and aesthetically pleasing, it is important to provide easy access to employment areas. This may be achieved through additional integration of transit within employment areas, and the creation of safe and direct bicycle and pedestrian connections. The provision of multi-modal connections to workplaces is a critical element to not only link people to their work sites, but to also provide employees access to a convenient mix of supportive uses around their workplaces. Another important element of employment centers are places for people to gather and recreate. It is important to design amenities into workplaces that allow employees or visitors to gather and recreate, such as plazas and courtyards.

A City enhanced with distinctive public art and cultural amenities.
Public art and cultural amenities have the potential to enliven public spaces and build a sense of community identity. The City of San Diego’s Public Art Program dates back to 1984 and has developed over the years, including adoption of the City of San Diego Commission for Arts and Culture’s Public Art Master Plan in 2004. Public art and cultural amenities can help to implement the City of Villages strategy, as they are an effective means to improve the quality of the built environment, contribute to economic prosperity, create great public spaces, foster cultural diversity, attract tourists, and celebrate the distinctiveness of San Diego’s neighborhoods. Public art and cultural amenities can also contribute to the City of Villages goal of creating more walkable communities by enlivening the streetscape and other public spaces. The following policies are intended to provide an overview of how public art and cultural amenities relate to the City’s planning and urban design goals. The following are policies related to public art and cultural amenities.

Council Policy 900-11 outlines a process for including public art in selected Capital Improvement Program (CIP) projects. The Public Art Program is to be funded by two percent of the budget for all eligible CIP projects over $250,000. Artists are to be involved in the early stages of project design so that they may become an integral part of the design process.
The City Council has amended the Municipal Code (Chapter 2, Article 6, Division 7) to require certain private developers to set aside one percent of their project budgets for art and cultural enhancement. The ordinance applies to eligible private commercial and industrial developments with a total building permit valuation equal to or in excess of $5 million dollars. This requirement may be satisfied by the financing of cultural and artistic facilities and/or on-site artwork. Private developers also have the option to pay a one half percent in-lieu fee. In-lieu fees are used for artistic enrichment of the City’s public spaces.
d. In high foot traffic areas, use pedestrian-oriented art interventions to enhance the pedestrian experience.
