vision plan parkmerced DRAFT 10.14.10 The Parkmerced Vision Plan lays out a conceptual framework for transforming the existing Parkmerced housing development into a 21st century model of a healthy neighborhood. Based on the vision set forth, the accompanying Design Standards and Guidelines, Sustainability Plan, Transportation Plan, and Infrastructure Report combine to create a comprehensive blueprint for guiding all future improvements to Parkmerced. - The Design Standards and Guidelines prescribe urban design controls for land use, open spaces, streets, blocks and individual buildings. It also outlines a process for project implementation. - The Sustainability Plan contains specific strategies and metrics which together address the management and conservation of energy, water and other natural resources, as well as establish goals for green building standards. - The Transportation Plan provides a framework and management plan for addressing transit and vehicular travel to and from the neighborhood. - The Infrastructure Report establishes an outline for anticipated site-wide improvements to all streets and public rights-of-way, underground utilities, and grading. The vision has been developed through a collaborative process with input from community members, local agencies and departments, public advocacy organizations and design and engineering experts.

The re-imagined Parkmerced will offer its residents and neighbors a diversity of housing opportunities, a range of new open spaces, and convenient neighborhood services and amenities. The main goal in re-inventing Parkmerced will be to craft a vibrant, pedestrian focused neighborhood where public spaces and buildings frame a comfortable public realm and make a positive contribution to the ecological and social health of the region and the city. As a part of this effort, a variety of new alternative transit opportunities are proposed to help reduce this portion of the city’s over-reliance on cars. The M-Ocean View light rail Muni line is intended to travel through the heart of Parkmerced, car and bike share pods are meant to dot the neighborhood, and a low-emissions shuttle is proposed to provide reliable service between Parkmerced and the nearby Daly City BART Station. In the process, the neighborhood hydrology will be repaired by day-lighting the flow of rainwater runoff as it passes through Parkmerced, allowing it to follow a more natural process. This will in turn help increase habitat and enhance the biodiversity of the neighborhood that was built over when Parkmerced was first constructed. The Parkmerced Vision Plan is intended to provide a conceptual framework that inspires innovation and high quality in each specific project within the neighborhood. The Parkmerced design and planning team, in close collaboration with the San Francisco Planning Department, has crafted the Parkmerced Vision Plan to include the following: - Urban design principles and goals that set out an insightful vision for the future of Parkmerced; - The ecological and social imperative for why Parkmerced should be re-invented; and - Strategies that support the stated ecological, social and urban design principles and goals. DRAFT 5 principles Convenient, local-serving amenities, a diverse mix of housing and a variety of outdoor activities will enliven the public realm and promote a socially vibrant neighborhood where people are the most important ingredient. The presence of a regenerative network comprised of deeply interconnected urban and natural systems will establish an ecologically healthy neighborhood. Focused growth integrated with access to viable alternative transit options will encourage walking, biking and other forms of green mobility. Open spaces, streets and buildings that are designed to be pedestrian focused will provide a comfortable and aesthetically rich environment. With input from residents, interested com- munity members, relevant City and State agencies and departments, planning ex- perts and public advocacy groups, the fol- lowing planning principles have been es- tablished in order to guide Parkmerced into the future.

At the time of Parkmerced’s original construction, planning strategies neither understood nor attended to the natural function of existing ecological systems that passed through the site. While the street pattern layout and land use organization represented a new vision of how neighborhoods should be planned at that time, the original Parkmerced was a suburban vision for a single-use neighborhood where cars dominated as the primary mode of transportation for residents to meet their daily needs. Over time this original strategy led to Parkmerced’s isolation from the surrounding Westside community and the rest of San Francisco both physically and in terms of its neighborhood character. Parkmerced is symptomatic of settlement patterns which have resulted in suburban sprawl across the region. This trend towards sprawl has: led to a loss of natural and agricultural lands, impairing the region’s ecological function; created longer commutes, resulting in lost work productivity and a lower quality of life; and required greater resource consumption, increasing each person’s carbon footprint. Additionally, this has resulted in an increased burden to regional roadways and city streets, which must manage the increase of pass-through traffic due to the daily influx of commuters and their cars. DRAFT 13 PARKMERCED OCCUPIES THE TRANSITION ZONEDRAFT BETWEEN THE CITY AND THE NATURAL REALM. DRAFT Historic San Francisco creeks and wetlands, circa 1890 Westside Groundwater Basin SITE Landfill Historic Creeks Historic Marshes 16 │ P A R K M E R C E D V I S I O N P L A N / 1 0 . 1 4 . 1 0 Characterized as a Franciscan biological region, Lake Merced is one of the last remnants of this native habitat. Protecting the ecology of Lake Merced is critical to ensure the natural watershed habitat is capable of sustaining native wildlife and preserving Lake Merced as a crucial nesting site for waterfowl and shorebirds along the Pacific Coast flyway (San Francisco Recreation & Parks). Parkmerced is located within the watershed that feeds and nourishes Lake Merced. Historically, rainwater in this natural drainage basin flowed towards Lake Merced to the west, with surface water runoff cleansed and absorbed by a healthy riparian habitat which was characterized by a vegetative cover of coastal shrubs and plant life. The rainwater also infiltrated the highly permeable sand and gravel soils, recharging the Westside Basin Aquifer which stretches from Golden Gate Park to the City of South San Francisco. In 1905, renowned American architect and planner Daniel Burnham presented his master plan for San Francisco. At that time, Lake Merced, owned by Spring Valley Water Company, was still the City’s potable water source. In response to this condition, Burnham proposed a great open space preserve (larger than Golden Gate Park) to protect the Lake Merced watershed, including the lands currently occupied by Parkmerced. However, after the 1906 earthquake, San Francisco built the Hetch Hetchy water system, originating high in the Sierra Mountains, in order to develop an independent and secure potable water source. watershed habitat “Once a remote and rural corner of the City, the lake environs have become increasingly urbanized over the decades, and the lake has had to endure the consequences, including a shrinking watershed, increased stormwater runoff, decreased groundwater recharge, increased demand for recreation, and increased wear and tear on facilities and the natural environment.” SFPUC, Draft Lake Merced Watershed Report, 2010 DRAFT Burnham master plan, 1905 Lake Merced, 1929 Lake Merced, 1953 Lake Merced, present SITE SITE SITE SITE Westside Groundwater Basin │ 17 1 0 . 1 4 . 1 0 / P A R K M E R C E D V I S I O N P L A N Once this happened, the City quickly began to develop over Lake Merced’s watershed. The natural water con- veyance system was severely altered, and replaced by the establishment of a completely separate, underground sew- er and rainwater conveyance system, leading out to the City’s Oceanside Wastewater Treatment Facility. Large swaths of impermeable surfaces, consisting of city streets, surface parking lots and building roofs, have further im- paired the natural watershed function by severely limiting the amount of rainwater infiltration and recharge to the un- derground aquifer. Diverted surface runoff increases the burden on San Francisco’s combined sewer-stormwater system and the potential for overflows into the ocean at the nearby treatment facility (Pezzetti et al. 1998, CDM 1999). When the site was initially developed in the 1940’s, wide- scale grading radically transformed the site’s natural to- pography into a generally flat table top, tilted slightly to- ward the west. Soils filled the original drainage ways, and an underground system replaced the natural watershed, so that rainwater was quickly put into pipes and moved off-site to the City’s treatment facility. This deprived the site, the lake and the underground aquifer of much of its annual rainfall. The vast areas of planted lawn, which was typical of the landscape fashion of that time, require approximately 55 million gallons of potable city water for irrigation. Large quantities of chemical fertilizers are also necessary to maintain the expansive lawn areas and non-indigenous plant species. Each year some of this fertilizer runs off into surrounding streams and Lake Merced and has been iden- tified as a potential cause of algae blooms in the Lake due to nutrient overload (Friends of Lake Merced, 2000). These practices can no longer be sustained. DRAFT 1950’s Marketing Materials 18 │ P A R K M E R C E D V I S I O N P L A N / 1 0 . 1 4 . 1 0 Constructed between 1941 and 1951, Metropolitan Life Insurance Company (MetLife) built the original Parkmerced residential complex as a response to the surging population and the associated demand for housing in the Bay Area, resulting from war preparedness efforts and continuing through the end of World War II. MetLife hired Leonard Schultze & Associates of New York to design the street grid, open spaces, and buildings at Parkmerced as one in a series of planned residential communities located throughout the country, including Park La Brea in Los Angeles, Parkfairfax in Virginia, Parkchester in New York and Peter Cooper Village / Stuyvesant Town in New York City. Thomas Church and Robert Royston developed the landscape design for Parkmerced. The original property contained 47 residential blocks, totaling 192 acres, including associated service buildings and open spaces. Based on urban planning principles of the time and a growing reliance on the automobile as a major transportation mode, Parkmerced was conceived of and marketed as ‘suburban living in the city’. This desire for suburban-style living led to the creation of an auto-oriented neighborhood with: large-scale blocks; roundabouts; and long distances to services and amenities. This plan locked future generations of residents into daily life patterns that are almost wholly dependent upon the car, isolating Parkmerced residents from the mixed-use, transit-based lifestyle that is enjoyed by most San Franciscans.

Their viability became untenable over the years as residents drove their cars to more easily accessible and convenient services and amenities. After MetLife sold the property, a subsequent owner sold off these parcels to others as a means to reduce overhead and maximize profitability. The current ownership group took over the property in October 2005. The neighborhood currently encompasses 152 acres, approximately 80 percent of the original Parkmerced property and contains 3,221 existing rental apartments in 170 two-story residential buildings (referred to as “garden apartments”) and 11 13-story residential mid-rise buildings. The property also contains associated parking, building services, a leasing/operations office, and a recently constructed private pre-school/day care facility. Parkmerced remains an example of a highly resource consumptive planning model. Residential trip surveys performed in 2006 indicate an average of over 6 non-work related vehicle trips per unit per day to other neighborhoods for basic services, shopping and amenities. Parkmerced’s landscapes consume over 55 million gallons of potable water per year for maintenance and irrigation. By the completion of the Parkmerced plan the garden apartments will be approximately eighty years old; they are un-insulated and have poor ventilation due to the construction methodology employed during war-time material shortages. In addition, these buildings do not provide barrier-free access and socially turn their back on the street, greatly reducing the vibrancy and sense of security of the public realm. 1 2 3 5 4 6 1 2 3 4 5 6 Parkmerced, circa 2010 ...parkmerced now DRAFT Bay area average commute time has doubled since 1987 2010 - 300,0001960 - 122,000 NUMBERS OF COMMUTERS P A R K M E R C E D V I S I O N P L A N / 1 0 . 1 4 . 1 020 │ imperative for the city “We cannot afford another generation of sprawl. Businesses suffer from higher costs, loss in worker productivity and underutilized investments in older communities.” Bank of America, et.al., Beyond Sprawl, Web 1996. According to the Association of Bay Area Governments, the San Francisco Bay Area population is set to increase by 2 million residents over the next 25 years. Increasing housing opportunities within existing urban centers is imperative to help address the region’s current unsustainable settlement patterns. The human, economic and ecological health of the region is at stake. With 41.2% of California’s total GHG emissions coming from transportation, auto-dependant land use patterns are one of the single largest contributors to the regions annual CO2 emissions of roughly 12 tons per person (Inventory of California Greenhouse Gas Emissions and Sinks: 1990 to 2002 Update, California Energy Commission, 2005). Lack of affordable housing opportunities in close proximity to public transit and existing job centers is forcing more and more Bay Area residents to commute longer distances, stuck behind the steering wheel of a car rather than at work or at home with their families. Inundating our region’s highways with daily commuters, the economic impact of traffic congestion costs the region nearly $3 billion a year in extra fuel costs and wasted time due to lost productivity (the U.S. Department of Transportation and Caltrans). GHG emissions are also a major contributor to global and local ecological degradation, resulting in an increase in surface air temperature and “killer” heat waves, rising sea levels, increased flooding, decreased air quality, and a reduction of wildlife habitat1. The design and scale of the future Parkmerced will substantially reduce miles traveled by car and contribute towards achieving regional economic and environmental goals for increasing resource efficiency. The Parkmerced vision is a once in a lifetime opportunity to transform a large, aging housing complex into a vibrant, model of an ecologically sustainable, walkable community. Transforming Parkmerced will directly result in a reduction in resource consumption and waste production while at the same time increasing the quality of life for its residents. Parkmerced is one of the most important, long-range redevelopment projects in the nation and will set the bar for this century’s sustainable communities. DRAFT 1 Kattenberg, A., F. Giorgi, H.

The following planning frameworks will function in unison to promote ecological living and reduce natural resource consumption while at the same time increasing social livability and encouraging an economically vibrant neighborhood. By doing so Parkmerced is set to shift towards a renewable energy-based, pedestrian-focused neighborhood, linked to the rest of the city through a diverse public realm network and a system of alternative transit, and therefore, bringing the community more in balance with the natural ecology of the site. Parkmerced’s vision for a 21st century healthy neighborhood includes: - Healing the community’s relationship to the land upon which it sits; - Providing a range of housing opportunities for a diverse population; - Creating a variety of recreational and passive open spaces; - Offering a lifestyle not dependent upon automobiles; - Establishing a more efficient use of resources; and - Reducing residents’ contributions to carbon production.

The re-imagined Parkmerced neighborhood will include a variety of neighborhood services and amenities, giving residents the choice of fulfilling their daily needs without getting in their cars. With these services and amenities located within comfortable walking distance, residents will be able to walk their children to school on their way to the train in the morning or stop at the market to pick up groceries on their way home in the evening. The central neighborhood serving retail will be located along and near Crespi Drive. Similar to other San Francisco neighborhood retail streets, Crespi Drive will be Parkmerced’s ‘social heart’, providing a place where residents can meet their everyday needs and socialize with their neighbors. To further increase Parkmerced’s social livability and ecological sustainability, a network of smaller, social gathering places (known as “Neighborhood Commons”) will fall within a two-minute walk of most residents and is intended to consist of small retail shops, business centers, neighborhood amenities and bicycle / carshare pods, all anchored by a major neighborhood park. To encourage and promote the art of ‘well-being’, Parkmerced will seamlessly weave together fitness, food production and positive social interaction. Located along the project’s southern edge, the Community Center will offer residents a variety of uses and programs relating to fitness, learning and wellness. Immediately to the east, outdoor flexible recreational spaces will provide opportunities for soccer, softball or other similar activities. As a critical component of any healthy neighborhood, the pre-school / K-5 location just south of the social heart will make Parkmerced a perfect place for families to call home. Located immediately west of the Community Center, an organic farm of approximately 2- to 3- acres in area will act as a source for local food production, providing fruits and vegetables for sale at the neighborhood grocery store, local farmer’s markets or in local restaurants.

Shop, Work and Support Introducing a new variety of uses into Parkmerced increases the livability of the neighborhood, as well as reduces the impacts residents currently have on local and global ecological systems. Education + Well-Being To increase the social vibrancy and importance of the social heart, the school site is centrally located and accessible to all Parkmerced residents. Living well and being well are critical not only to sustain life, but for life to thrive.

Parkmerced’s landscapes will reinvigorate the site’s hydrology, reestablish biodiversity and reconnect to Lake Merced, while offering a comfortable setting for the community’s outdoor activities. The Parkmerced landscape will create a varied series of neighborhood open spaces that support structured and unstructured recreation for groups as well as individuals. From the semi-private courtyards that encourage neighbors to interact with each other to the public parks and plazas that provide places for the neighborhood to gather, Parkmerced will provide a range of outdoor experiences that enrich the social life of the neighborhood. The Vision Plan builds on ideas to regenerate the underlying watershed and site ecology while supporting a socially sustainable neighborhood. The stream corridor will be the backbone of the habitat restoration with it’s resource rich environment attracting an array of native wildlife. Only native, acclimated or wildlife friendly plant species will be used on site, both to minimize water consumption and to attract native wildlife. Finally, in order to protect biodiversity and public health, landscape maintenance will follow integrated pest management and organic farming methods. The landscape will create a variety of other ecological zones including wetlands, coastal woodlands, and meadows. urban + natural systems open space Parkmerced will embrace a new paradigm, where open spaces are meant to provide benefits for both people and the functioning of ecological systems. 26 │ P A R K M E R C E D V I S I O N P L A N / 1 0 . 1 4 . 1 0 DRAFT B R O T H E R H O O D W A Y L A K E M E R C E D B O U L E V A R D 1 9 T H A V E N U E J U N I P E R O S E R R A B O U L E V A R D H O L L O W A Y A V E N U E F O N T B O U L E V A R D S A N F R A N C I S C O S T A T E U N I V E R S I T Y S A N F R A N C I S C O G O L F C L U B M E R C E D H E I G H T S L A K E M E R C E D NEIGHBORHOOD PARKS FOREST ORGANIC FARM STREAM CORRIDOR COMMUNITY GARDENS HEDGEROW TREES PRIVATE OPEN SPACE / COURTYARDS Green Connector Connecting the eastern and western edges Parkmerced Gonzalez Drive weaves through the neighborhood creating a robust green link for people, water and habitat from SFSU to Lake Merced.

Reflecting an emerging understanding of the negative impacts cars have on the ecological and social health of our communities, Parkmerced will transform the street by reducing the amount of roadway dedicated to cars and increasing the space given to people and underlying ecological systems. Streets at Parkmerced will weave together social and ecological project benefits through a network of functions like: sitting, walking and bicycling; and gathering, retaining and cleansing rainwater. Creative and straightforward street designs will translate into a variety of simple and functional streetscapes. Gonzalez Drive and other secondary streets will help orient people as they move through the neighborhood. Hedgerow streets will be planted with wind buffering trees to address persistent cold winds from the west.

The redefined landscapes at Parkmerced will feature rainwater runoff treatment as a prominent design feature. A series of landscape elements including: biogutters; bioswales; a new stream corridor; and ponds and wetlands will filter and clean rainwater before discharging cleansed water into Lake Merced. The armature for this water movement will be a new branch-like network, leading from rooftops all the way to Lake Merced. Rainwater is intended to travel from roof downspouts to biogutters, into a large series of bioswales, and then into a seasonal stream with a “laddered” series of ponds and check dams, leading to a terminal wetland / pond which finally outflows to Lake Merced. Permeable paving, installed at the alley streets and courtyards, will allow rainwater to infiltrate the ground. Since water will be more efficiently distributed to the landscape and native or ecologically sensitive plants will be used, irrigation water needs will be reduced by 50%. urban + natural systems site hydrology The future hydrology goals for the Parkmerced neighborhood focus on conserving every drop of water and putting it to use in regenerating a landscape naturally in balance with the climate and rainfall.

The plant palette is further limited by the desire to use only native or acclimated species, ones which will require little or no irrigation once established. The recommended plant list, as described in the landscape design guidelines, was developed in collaboration with one of the most respected horticulturists in the Bay Area, Barrie Coate, who carefully selected species to meet both the sustainable and aesthetic needs of the project. Species were considered based on the following categories: aesthetics, scale, micro- climate, water-conserving, native, water and wind tolerance, density, and transparency. urban + natural systems urban forest The Parkmerced micro-climate is the dominating factor in guiding tree selection.

By providing a wide range of opportunities for residents to engage in recreational activities, Parkmerced is meant to be a neighborhood where people of all ages and abilities are encouraged to participate in some form of healthy, physical activity. As the nerve center for a network of recreational and outdoor activities, the Community and Fitness Center is a place dedicated to social interaction, health and well-being. Located at the southern edge of the ‘social heart’ the Community and Fitness Center will include a gym, swimming pools, sports fields and other spaces and services focused on recreation and healing. Adjacent to the Community and Fitness Center is the ‘stream corridor’, providing a beautiful and rejuvenating setting for those residents that are drawn to quieter, slower paced forms of physical recreation, such as strolling or meditation. Community gardens provide an opportunity for those who enjoy the art of cultivation and getting their hands dirty while being physically engaged. Filling out the network is a robust system of bicycle and pedestrian paths, linking these vital spaces together and connecting them to places such as Lake Merced and a larger fabric of citywide opportunities for recreation and outdoor activity. socially vibrant neighborhood recreation Weaving recreation and outdoor activities throughout the public realm will help enliven the neighborhood by encouraging more people to spend more time outside, while promoting healthier life styles.

Parkmerced proposes to provide a convenient transit alternative and tie the neighborhood to the rest of the city, by rerouting the M-Ocean View Muni line from 19th Avenue, between Holloway Avenue and Junipero Serra Boulevard, into the heart of neighborhood and then back to its current alignment. Associated with this new section of the M-Muni line would be three new Muni stations. At the northeastern edge of the Parkmerced ‘social heart’ a new transit plaza is intended to include: a new Muni light rail station; bus stops; coffee and news stands; and comfortable, sheltered areas to wait. An additional station adjacent to the new grocery store is centrally located within the ‘social heart’. The terminal station at Font and Chumasero will provide convenient access to residents in the southern-most part of the site and will also allow for a future Muni connection to BART or accommodate MTA’s TEP J-Line re-routing to this area. Development intensity is meant to be greatest around these new stations, capitalizing on the level of activity that they would bring to the neighborhood. Making mass transit a more viable and convenient option for Parkmerced residents the new Muni stops are intended to be within a comfortable 10-minute walk for all residents. green mobility light rail Like many other San Francisco neighborhoods, Parkmerced will be a transit oriented neighborhood, connected to the rest of the city by Muni.

Streets will be designed to provide a sheltered environment, buffered against persistent cold winds from the west, while ample sidewalks will allow residents to comfortably walk through the neighborhood alone or in groups. Narrower curb-to-curb dimensions and other methods of reducing crossing distances will increase pedestrian safety and in turn increase the likelihood that people will choose walking as a primary mode of mobility. A robust network of alleys, paseos and walks will allow people to meander through the Parkmerced neighborhood and enjoy a landscape where the priority of cars has been greatly diminished. Walking is widely recognized to be beneficial for human health. Walkers have a lower incidence of cancer, heart disease, stroke, diabetes and other diseases. They live longer, receive mental health and spiritual benefits and are more likely to be actively engaged in their communities. It is safe to state that an increase in neighborhood walkability will have a direct impact on the overall health, well-being and social vitality of a neighborhood. green mobility pedestrian Streets at Parkmerced will be for people first.

Gonzalez Drive and Font Blvd. will be primary vehicular streets, providing two clear paths for vehicles to access the neighborhood. Giving residents a direct route within the neighborhood is a structure of secondary access streets branching off of Gonzalez Drive and Font Blvd. With signifi- cantly lower volumes of vehicular movement, neighborhood and alley ways are intended to provide localized access and typically are no longer than a few blocks. Preferred garage entry locations are along the neighborhood streets; while the Alley Ways are intended to be pedestrian focused, shared streets, where cars must slow down to share the road with pedestrians. Distributed throughout Parkmerced, car share hubs will pro- vide easy access to a variety of different car types, which will offer a convenient alternative to car ownership. green mobility vehicle Streets at Parkmerced will help ease vehicular movement through the neighborhood by increasing access to the site and providing a clear hierarchy between primary access and neighborhood streets.

A disproportionate area of urbanized land is dedicated to one form of parking or another. As society’s fascina- tion with cars wanes, new approaches to where cars are parked have begun to emerge. In order to create a public realm, includ- ing streetscapes that are primarily dominated by people and land- scape, most parked cars will be below grade, freeing up on grade space for courtyards, Neighborhood Commons and other outdoor spaces. This will help to further establish a healthy relationship between the inside of buildings and the outdoors. When cars are parked above grade they will be screened behind active, socially engaging spaces such as commercial or housing. This aggressive parking strategy will allow residents to treat parking as ‘car storage’, encouraging those residents that live in the center of the neighborhood to use transit and other forms of ‘green mobility’ in order to meet daily needs. All off-street parking at Parkmerced will be ‘unbundled’ from the rental or pur- chase fees for residential units, eliminating a financial burden for those that choose not to own a car. The neighborhood is divided into four parking zones: 1. Areas where no parking is allowed. 2. Areas with one level of below grade parking. 3. Areas with two levels of below grade parking. 4. Areas with above grade parking. To support those residents that choose not to own a car, car share facilities will be strategically located throughout the neigh- borhood to further increase access to a variety of mobility oppor- tunities for residents of Parkmerced. These facilities are gener- ally located adjacent to Neighborhood Commons or the ‘social heart’ to help capitalize on the comings and goings of people as they utilize these neighborhood services. green mobility parking + garage storage The parking strategy at Parkmerced is intended to reduce the visual impact of parked cars on the pedestrian environment while simultaneously encourage the use of other forms of mobility. 48 │ P A R K M E R C E D V I S I O N P L A N / 1 0 . 1 4 . 1 0 DRAFT B R O T H E R H O O D W A Y L A K E M E R C E D B O U L E V A R D 1 9 T H A V E N U E J U N I P E R O S E R R A B O U L E V A R D H O L L O W A Y A V E N U E F O N T B O U L E V A R D S A N F R A N C I S C O S T A T E U N I V E R S I T Y S A N F R A N C I S C O G O L F C L U B M E R C E D H E I G H T S L A K E M E R C E D ABOVE GRADE PARKING ZONE 1b NO PARKING BELOW GRADE PARKING ZONE 1a BELOW GRADE PARKING ZONE 2 CAR SHARE Car Share Strategically located throughout the neighborhood car share ‘pods’ will provide residents of Parkmerced with a variety of types of cars for a range of uses such as a regional outing or moving furniture. Below Grade Parking The vast majority of parking is located below grade, allowing for a seamless ground plane, uninterupted by parking lots, parked cars or unsightly parking structures. Above Grade Parking Lining above grade parking structures with lively uses that engage the public realm eliminates dead streetedges while providing adequate parking to serve the neighborhood. Unbundled Parking Locating the majority parking stalls on the west side of Parkmerced, away from transit encourages people to think twice before getting in the car to go to the grocery store.

A critical component to the implementa- tion of the Parkmerced infrastructure will be to provide flex- ibility in the future to incorporate the best, new and emerg- ing technologies as they become available. As a complete neighborhood plan Parkmerced offers a unique opportu- nity to employ green infrastructure elements at a district scale, increasing the effectiveness of each strategy. Energy To reduce greenhouse gas emissions and energy con- sumed by buildings, Parkmerced will deploy a compre- hensive energy strategy. Parkmerced will utilize creative, yet practical solutions to help offset the anticipated energy demands of future residents, including: high-performance building envelopes; passive solar design; installation of renewable energy systems; and integrated district energy systems. Renewable energy systems such as photovoltaic solar collectors and wind turbines will produce a percentage of Parkmerced’s energy, reducing the need for off-site ener- gy supplies. Cogeneration facilities will act as micro-power plants for the neighborhood and are capable of function- ing from a wide variety of primary energy sources, including natural gas and biomass. Tying this entire system together would be a potential district energy loop, efficiently distrib- uting electricity and hot water throughout the neighborhood. Water By utilizing the combined sewer system for household sani- tary sewage only, rainwater at Parkmerced can be treated as a resource. Collecting rainwater runoff through a combi- nation of low impact development techniques including bio- swales and other bio-filtration systems will help restore the natural hydrology of the site. The annual volume of water for irrigation, for approximately the same number of acres of open space, is expected to decrease from roughly 55 mil- lion gallons of potable water per year (MG/yr) to just over 30 MG/yr of recycled and/or grey water. urban + natural systems green infrastructure Infrastructure at Parkmerced will be created as an interconnected and mutually supportive network of urban and natural systems intended to reduce overall resource consumption. Through installation of efficient fixtures for low flow toilets, sinks, showers, and laundry machines in both new and ex- isting units and the use of recycled and/or grey water, the average residential water use at Parkmerced is targeted to be reduced to 38 gallons per capita per day. This will re- sult in less flow to San Francisco’s Oceanside Wastewater Treatment Facility, which translates to less chemical use, lower energy usage, and a reduction in overflows of effluent into the Pacific Ocean. Waste Supporting San Francisco’s ambitious goal for “Zero waste to landfill by 2020”, Parkmerced will make zero waste practices easier for residents, keep construction waste di- rected to landfill to a minimum, and implement simple, yet effective maintenance practices in order to reduce unnec- essary collection of yard waste. Reducing the amount of waste directed to landfill will also reduce the vehicle trips needed to haul solid waste from the site. This in turn will help to reduce the overall GHG emissions for the entire neighborhood. Establishing an on-site, ‘green food chain’, Parkmerced will compost yard waste and use it to fertilize landscape areas. 50 │ P A R K M E R C E D V I S I O N P L A N / 1 0 . 1 4 . 1 0 DRAFT B R O T H E R H O O D W A Y L A K E M E R C E D B O U L E V A R D 1 9 T H A V E N U E J U N I P E R O S E R R A B O U L E V A R D H O L L O W A Y A V E N U E F O N T B O U L E V A R D S A N F R A N C I S C O S T A T E U N I V E R S I T Y S A N F R A N C I S C O G O L F C L U B M E R C E D H E I G H T S L A K E M E R C E D Water Recycling Parkmerced will utilize a dual plumbing system for recycled water. Recycled water will be used for irrigation, laundry and toilet flushing. Air-Source Heat Pump Utilizing waste heat from commercial uses to help heat water as it passes through the District Water Loop helps reduce unnecessary consumption of natural resources and provides cooling for retail and office uses. Wind Turbines Wind turbines will produce a percentage of the Parkmerced’s energy, limiting the need for off-site energy supplies. A possible location for wind turbines is along Lake Merced Boulevard. Solar Ready All buildings at Parkmerced are required to design at least 50% of their roof area to permit installation of south facing solar collectors. District Energy + Water Loop A potential district wide energy and hot water loop would allow for all systems to tie together and direct resource flow to where it is needed most. Micro Power Grids Within each block is the potential for the creation of a small scale energy grid, complete with cogeneration equipment that convert waste heat into a useful energy source. Green Food Chain Parkmerced will compost yard waste and use it to fertilize landscape area and the Organic Farm. The Organic Farm will cultivate produce that can be sold in neighborhood markets and restaurants. │ 51 DRAFT Green Infrastructure 1 0 . 1 4 . 1 0 / P A R K M E R C E D V I S I O N P L A N Reflecting this diversity, Parkmerced will be a place for families with children, couples, singles, and seniors from all walks of life. A predominantly low-rise neighborhood, punctuated by taller and medium-size residential buildings, the Parkmerced’s urban form of will focus the greatest de- velopment intensity in and around the social heart of the neighborhood and the new Muni Stations. Following the natural topography of the site, overall building massing and heights are generally lower in the western portions of the neighborhood. With a variety of townhome units, walk-ups, live/work flex spaces, flats and other types of residential dwelling units, and a range of studios, one-, two- and three-bedroom units, Parkmerced will also offer for-sale or rental living op- tions that will be necessary in fostering a diverse resident population. Increasing the number of homes within Park- merced will help increase the social vibrancy of this corner of San Francisco; minimize the number of car trips that are clogging local streets; increase the viability of neighbor- hood retail services and amenities; and play an important role in reducing the impacts of human settlement on local and global ecological systems. New townhomes and walk-ups: 3 Stories At 35’ in height, towhhomes and walk-ups will be located primarily in the western portion of Parkmerced, creating a fine-grained residential character and reducing the overall neighborhood massing as it gets closer to Lake Merced.
