Final Conceptual Site Design A 3.5-acre abandoned parking lot site adjacent to the Ashuelot River is transformed into a vibrant greenspace and community event space in Keene, NH. This park includes a natural playground, a space for the Keene Farmers’ Market, a wildflower meadow designed to bio-remediate the heavily impacted soils, and plenty of wayfinding and informational signage to orient visitors to the site and its surroundings - including adjacent bike path and other recreational opportunities.

Explore. Boaters enjoy easy access to the river, and maps invite passing cyclists and other visitors to explore the surrounding area, and the beautiful Ashuelot River Park.

Power. Solar panels provide renewable energy for the city.

Shop Locally. On market days, residents shop for local produce, prepared foods, and crafts at the Keene Farmers Market. Connect. The pavilion becomes an event space, where the community can come together to enjoy concerts, outdoor movies, or public art displays.

Play. A centralized playground made of all natural materials brings families to the site.

Learn. Interpretive signs teach residents about the history and ecology of the area, and about the site’s green infrastructure.

Thrive. Native vegetation creates habitat for insects, birds and animals.

Reflect. Quiet nooks and shady edges offer visitors secluded areas to look out over the meadow and river.

Contextual Analysis & Assessment

Ashuelot River Park

The site is very centrally located, between several existing open-space and recreational areas (including the 175-acre Ashuelot River Park), a large residential neighborhood, and near downtown Keene. This location, combined with the fact that downtown Keene has very few green-spaces, make this a great location for a new park, playground and community event space.

To help determine appropriate uses for the new greenspace, the Keene Comprehensive Master Plan and Recreation Plan were both consulted. The plans recommended, among other things: • Increased walkability and bike connections • Planning for climate change • Increased flood mitigation • Increased city-wide stormwater infiltration • Design to improve the health of the community • Design to encourage alternative transportation • Design to encourage positive activities for youth • Design to increase connectivity among alternative transportation • Expanding open space/conservation land • Increased Historical and environmental signage


Site Analysis & Assessment The soils on site are mostly fill, with limited organic matter, and are heavily impacted. Remediation will be necessary in order to re-vegetate the site. The site is almost all within the 100-year floodplain, although controls from the Surry Dam mean that it will most likely never flood. However, designs will have to take into account a high water table as well as FEMA floodplain regulations regarding cut and fill.

Example Soil Amendment Techniques:

2-3 inches

2-3" of compost (the amount of soil that could be brought in under FEMA floodplain regulations) could be brought k in and tilled into the fill, then planted with cover crops or a tolerant biomass-building meadow mix to build biomass on site. k

A compost program could be started on-site by a nearby professional using wood chips and leaves from the Keene Public Works Department or food scraps from the farmers market. A photo taken of a soil pit dug in May 2015 shows that the top 2-3’ below the asphalt is made up primarily of fill with little to no organic matter

Driveway Recommendations Building a driveway to the top of the site from Laurie Drive will be expensive and require careful engineering. At this time, the best alternative seems to be to build a road through the pastures to the east.

Driveway #1: Up the Slope

Driveway #2: Around the South-side

Driveway #3: Through the Field

Master Plan Alternative

In order to help fund development, the lot is sub-divided and a lot to the north is sold at market rate. On the south side of the site, a small cluster development takes advantage of one of the only flat areas on the site. A A market rate lot in the northern part of the site can be reached by a

going straight down the shared driveway. Turning left leads to... B a parking court (16 cars) for small cluster development, with a fire-truck turn-around.

A

C Open commons and a shared garden space is fire-truck accessible. Houses on the stream side are single story with full basement. Houses on the pasture side are two stories, built into the hillside, acting as a retaining wall. Around the houses, mown turf and low plantings makes up the majority of the open space, with native shrubs placed as privacy screens. D A native meadow leads to a meandering woodland trail. At the edge of the woods shrubs and small trees create habitat, biodiversity and a buffer for the forest interior, which is planted with edibles and woody plants with bright fall foliage. At the end of the trail, benches look over sloping dairy pastures.

A network of swales and infiltration basins to retain and filter water from impermeable surfaces are necessary to avoid channeling the water, which could potentially greatly increase the already very problematic erosion on the site.

Site Analysis & Assessment Conditions on the site make building a road up the western slope inadvisable. There are flat areas for building, although these are relatively small, so alternative development strategies are recommended to make the most of the limited space. Run-off from the development will have to be carefully managed to reduce impact on the intermediate stream running along the west side of the site.

ATTACHED UNITS can save even more space, are often cheaper to build, and are not just for urban sites. Shown below is the Cheesecake Consortium, a co-housing community in a redwood forest

TRADITIONAL SUBURBAN DEVELOPMENT

• • •

Involves a lot of disturbance for only a handful of houses. Centers around cars. Doesn’t foster community.

Cluster developments are especially great for kids, who can wander and play freely.

POCKET NEIGHBORHOODS CAN BE A GREAT ALTERNATIVE FOR SENIOR CITIZENS. As the first wave of baby boomers reaches retirement, many such communities (sometimes called “saging communities”) are popping up. They often have community buildings to encourage interaction and to offer a space for residents to cook meals together and pursue hobbies and activities with like-minded individuals with similar needs. Below is shown Silver Sage, a senior-only cohousing development in Boulder, CO.

CLUSTER HOUSING • • • • •

Maximizes space on the site, allowing for many more houses. Fosters community, because the houses are arranged to encourage neighborly interaction. Encourages outdoor living, with a shared common green space in the center of the houses. Keeps cars at bay, and is designed to be human scale, and walkable. Allows the town to grow while still maintaining open space and farmland elsewhere.

Although it is not always possible to have parking right next to residents’ houses, as is the case in the cluster housing development above, many residents say that they enjoy walking from their cars as it gives them a chance to happen upon, and visit with, neighbors.

Cluster developments encourage neighborly interaction and foster community.

Taking it one step further... HOUSES DESIGNED FOR CLUSTERING are tall and narrow, with public rooms on one side and private on the other, to give residents a sense of separation even in tight quarters (houses below designed by Kraus-Fitch Architects in Amherst).

Alternative Development Strategies

This site has a limited amount of flat, buildable area, and access will most likely be expensive, so it is recommended that the Town look at development alternatives that maximize usable space.

Not for construction. Part of a student project and not based on a legal survey.

Preferred Conceptual Alternative Potential to add access road to connect to overow parking, event space and/or outdoor work area

Siting the barn directly to the north of the house makes it easily accessible, creates a sunny, enclosed space to the east of the house and south of the barn, and allows for an orientation that leaves open the option for roof-top solar panels in the future (a client request). It also creates nice views of the barn as you come up the driveway, as well as from the meadow to the south (not seen on map).

Farm operations are centralized around the flat sunny meadow in the south-eastern quadrant of the property, which will make a good place for siting future hoop-houses and growing crops. Future barn is located centrally between existing hoop-house and flat sunny meadow (future farm center) and all the working areas are on roughly on the same contour, making it easy to move around the farm. A thinned woodland area above the barn lets more light in to the house site and is an attractive setting for a trail from the house to the barn, and perhaps a future forest garden.

Rice-Wescott Homestead Ashfield, MA

Centralized farm operations are separated from the house. Views from the house to the south and east are preserved. Tractor activity is, for the most part, kept off the driveway that runs directly in front of the house. The meadows in front of the house become wildlife habitat areas. A “meadow loop trail� around this part of the property could visits different nodes on site, including a new small pond, as well as hooking into larger trail systems.

Black Brook Farm Growers Market Garden Carlisle, MA

During the Spring of 2011, my mother and I designed, built and planted a 1/3 acre market garden in Carlisle, MA. Over the following two years, we ran a 16 family CSA out of the garden, eventually turning it over to a colleague and friend who still farms there today. For more information (and pictures), visit bbfgrowers.com.
