INTRODUCTION, GOALS, AND COMMUNITY PROCESS

NOT FOR CONSTRUCTION. PART OF A STUDENT PROJECT AND NOT BASED ON A LEGAL SURVEY.

On May 6, 2015, the first of two public forums were held to gather public input on the design direction for the landscape master plan for Carpenter Street Field. Twenty-five citizens, users of the field, and city officials met at Bentley Commons. Students from the Conway School facilitated an hour-long workshop where participants were asked to identify their favorite features at Carpenter Street Field and what features they’d like to see incorporated into the design. The data collected helped inform the goals for the design. On June 6, 2015, students from the Conway School returned to show design alternatives and receive feedback on them. Twenty-two attendees, half of whom participated in the first forum, shared with the students what they would like to see in the final design.

In addition to the two public forums, there were over thirty responses to an on-line bulletin board that was open for over one month.

Ice cream truck stops for deliveries. Kids and adults enjoy more than sports at Carpenter Street Field.

Youth practicing lacrosse. Lacrosse is one of many sports played on the field. During practices most of the field is used.

An on-line community-wide survey asked residents to identify the features to be included in a design for Carpenter Street Field for generations to come. The most frequent responses included: • An easy connection to the Cheshire Rail Trail • A walking/jogging track around the field • Improved in-stream and stream-side habitat • A city-wide greenway along Beaver Brook

Field users, concerned citizens, and City officials engaged in design charrettes to help unlock the potential of Carpenter Street Field.

Currently CSF is heavily used for active recreation (sports that require a large field such as rugby, lacrosse, flag football, and ultimate frisbee). The field is also used for dog walking, sunbathing, practicing baseball, meetings, and playing on the swings and natural playground. There are some uses, mainly isolated to the northwest corner, deemed unsafe and unwanted by community members.

Client: City of Keene

The City of Keene envisions Carpenter Street Field (CSF) as an open space and recreational centerpiece for the redevelopment of the East Side Neighborhood. While there are many parks and open spaces on the west side of Keene, City officials and residents have expressed a desire for such public spaces on the east side. CSF is in a prime location, a quarter-mile from downtown, to help achieve the City’s goals. City officials believe that adding more features to the field will help to increase the variety of uses and users.

PARKING LOT

A handful of mature trees dot the western edge of the field, providing shade for park users. In the northeast corner a large (30’x10’) metal swing set sits against the dense vegetation. A small (~1200 square feet) fenced-in natural playground is along the eastern fence line. The 4’ chain-link fence runs the entirety of the eastern edge, separating the parking from the field.

DPR maintenance crews pick up trash twice a week and mow, aerate, and seed the lawn. The bank (covered in Japanese knotweed) is occasionally mowed too.

The backstop and adjoining diamond are available for practice but are not formalized for any sanctioned games.

EXISTING CONDITIONS

Along the northern edge, a dense wall of vegetation separates the residential backyards to the north from the top of the field. Along the eastern edge, a row of evenly spaced lindens provide shade for the off-street parking. A mix of businesses and residences line the eastern side of Carpenter Street. In the southeastern corner abutting the property line is a nondescript one-story cinder block storage garage. Also just beyond the southern property line is the former jewelry factory Findings. Findings owns the rectangular ~.6-acre lawn that abuts the City’s property. Occasionally practice takes place across the property line on this open lawn. The western edge of Carpenter Street Field drops steeply approximately 5’-8’ to Beaver Brook. Most of the brook is lined with Japanese knotweed and other invasive plant species.

The City Express Bus #5 stops in front of the former Mill Building on Railroad Street, a six-minute walk from CSF. The former mill building is home to market-rate senior housing, a Montessori school, and numerous health care businesses. Adding signs at the bus stop to guide visitors to the field and formalizing a path to the field may increase the number of users arriving by public transportation. The city-wide Cheshire Rail Trail comes within 500’ of CSF. The trail is used by bicyclists, skateboarders, roller skaters, walkers, and dog walkers. During the public forums citizens have identified creating a connection between CSF and the trail as a priority. Adding signs along the rail trail to guide visitors to the field and formalizing a path to the field may increase the number of users arriving by alternative transportation.

Senior Housing (former mill building)

Three senior housing centers (482 units) of various income levels are within a five-minute walk. New senior housing is to be completed late next summer (26 units). Flatter paths, frequent seating, and other active and passive recreational features on CSF could serve an elderly population.

Schools

Four schools are within a 15-minute walk. CSF could supplement play areas at schools and serve as an outdoor classroom for learning about brook hydrology, vegetation, and wildlife.

Cheshire Rail Trail

Cheshire Rail Trail is an east-west multi-use path. Benches along the path close to senior housing have been removed. The trail comes close (500’) to CSF but does not directly connect to it. A connection to the trail can assist in providing non-motorized access to CSF from downtown, other city parks, and western city neighborhoods.

The Railroad Land development, an area of high-density mixed use, began undergoing redevelopment in 2006 and is continuing to add new housing and businesses to this area which already includes many businesses (grocery store, restaurant, hotel, offices) and residences for a variety of income levels. Railroad Land extends east from Main Street to Beaver Brook. Carpenter Street Field is the closest open space for residents and workers in this area and downtown. Many of the residents living downtown and in the adjacent Railroad Land appreciate the walkabilty of the dense development here. Many housing units do not have private yards, and residents appreciate access to public green space.

Currently all formal access by street and sidewalk into CSF is from the residential areas in the east. The only access from the more dense and developed areas to the west is via an informal dirt path (~500’) from Harrison Street. The long dirt path connects to the northwest corner of the field and is neither universally accessible nor maintained.

The City is focused on redeveloping the east side of Keene. One aim of this redevelopment is to create more accessible open spaces for citizens of all ages and abilities to gather, play, and enjoy nature. Carpenter Street Field located at the intersection of more dense multiuse areas and residential neighborhoods can play an important role in achieving this aim.

dense and diverse neighborhood

Carpenter Street Field: A Landscape Master Plan

Dense urban development creates a more communityoriented and pedestrian-friendly atmosphere. Reducing reliance on vehicles and emissions they produce helps to mitigate for climate change. A key element of dense mixeduse urban areas is the inclusion of open space for individuals to gather and recreate. Having open space within walking distance of work and home has been shown to help increase one’s health, happiness, and civic pride.

The Beaver Brook Watershed becomes constricted by the built environment beginning at Concord Road (2.5 miles north of CSF). An increase in the amount of impervious surfaces reduce the areas alongside waterways to accommodate flood waters. Instead of being infiltrated into the ground close to the source, flood waters are forced to spread further out to storm drains and porous undeveloped land.

Watersheds

Section A-A’ Section A-A’

There is evidence that channelizing Beaver Brook began as far back as 1877. Altering waterways was common occurrence in the development of new settlements. Channelizing a brook could provide for multiple functions such as speeding up the waters to increase the potential with of harnessing hydro power, draining low-lying Confluence areas to be used for the Branch River industry or agriculture, and moving water downstream quicker. The altering of the brook seemed beneficial at the time but it has had long term negative consequences. Removing the natural meandering pattern of a lowland brook reduces the amount of bank side flood water storage. A straighter channel also provides fewer sites for wildlife to find shelter and food. A meandering brook slows the speed of water therefore reducing the potential erosion caused by flood waters flowing downstream during a storm. Downtown Keene: 1853

Concord Road

CSF

The Beaver Brook watershed is outlined in black. The landscape north of Concord Road can more easily accommodate stormwater at the source due to the permeability, rather than increasing the amount of water downstream. The landscape south of Concord Road is more built, therefore less permeable causing a wider extent of flood waters during heavy storms (Map from Beaver Brook Restoration Plan, Moosewood Ecological LLC, 2009).

Any work done at CSF to help ameliorate property damage due to flooding will be “a drop in the bucket” given its small size. A city-wide approach will be most effective in helping reduce the negative impacts of flooding on the built environment.

Maps show the growth of the built environment of Keene and the consequential realignment of Beaver Brook.

A section of Beaver Brook, 3/4 of a mile north of Carpenter Street Field, shows the realignment of a sinuous stream into a straight channel. The red line designates the unaltered path Beaver Brook took within a less built environment. The permeable land adjacent to the brook provides flood water storage and water filtration. A meandering brook slows the speed of water therefore reducing the potential erosion caused by flood waters flowing downstream during a storm (maps.google).

Janice Schmidt

Carpenter Street Field is within the lower end of the Beaver Brook watershed. The watershed covers approximately 10.4 square miles. The upper portion of the watershed is forested. Natural floodplains (vegetated and pervious) along the banks of waterways (rivers, brooks, and streams) help accommodate overflow during heavy rains.

13.8 Miles

Managing stormwater throughout the city is a high priority for the City of Keene. Keene sits in a basin formed by glacial Lake Ashuelot. Sediments left behind as the glacial lake retreated are fine and therefore not very permeable. Given the topography, soil characteristics, the amount of impervious surface, and the number of rivers flowing through the city, flooding is a potential threat to the built environment.

NOT FOR CONSTRUCTION. PART OF A STUDENT PROJECT AND NOT BASED ON A LEGAL SURVEY.

Many of the storm drains east of Main Street drain into Beaver Brook. During heavy rains Beaver Brook has to accommodate more water than during normal times therefore the frequency and amount of flooding that occurs at CSF is increased. The drains circled in yellow outfall in the stretch of Beaver Brook along CSF.

Impervious Surface

Most of downtown west of CSF is covered with buildings, parking lots, roads, and sidewalks. Stormwater largely drains into municipal drains and is not absorbed by the landscape.

100-Year Floodplain

Most of CSF is in the 100-year floodplain. The combination of low elevation, proximity to Beaver Brook, and stormwater draining into Beaver Brook increases the likelihood of the field flooding.

2012 Flood Area Data Source for GIS Maps: GRANIT: DATA SEARCH, CITY OF KEENE

In 2012, flood waters extended past the 100-year floodplain, affecting many residences and businesses. According to climate scientists at the UN and elsewhere, storms are becoming more severe, thus future flooding is likely to occur more frequently and with greater impact.

Janice Schmidt Aitan Mizrahi

Rainwater that flows along impervious surfaces can become contaminated with pollutants such as oils, and fertilizer. Pollution can have significant negative effects on ecosystem functions and biotic interactions. In addition, warmed by the impervious surfaces, runoff may alter the ecosystem of the brook by potentially decreasing the available oxygen and altering habitat for native species.

C o n w a y St u d e n t D e s i g n e r s :

Beaver Brook runs along the western edge of CSF and is heavily channelized. The brook is dredged following heavy flooding. During heavy storms, flood waters spill over the bank and extend beyond the property line of CSF, damaging buildings in all directions.

N E I G H B O R H O O D A N A LY S I S : HYDROLOGY

main st.

Because of these multiple factors, the amount of water that spills over the banks of Beaver Brook during a storm far exceeds the amount CSF could store even though it is an open field. Any work done to alter the shape and width of the brook and the adjacent bank could help to store stormwater, provide other ecological services such as creating a diversity of habitat, and slow the water down. The negative impacts of flooding needs to be addressed city-wide, particularly upstream.

Carpenter Street Field: A Landscape Master Plan

Stormdrain Watershed

Within a half-mile of Carpenter Street, especially westward towards downtown, a high proportion of the ground is covered by impervious surfaces (concrete, asphalt, and buildings). Rainwater falling on these surfaces flows into storm drains and is carried in pipes underground. Many of these storm drains lead to Beaver Brook. The force of the water leaving the pipes may cause erosion along its banks.

According to UMASS Soil and Plant Tissue Testing Lab, none of the samples are above the US Environmental Protection Agencyâ&#x20AC;&#x2122;s threshold standards. The low level of heavy metals in the soils indicates the field is likely safe for children, who are more susceptible to the ill effects of heavy metals.

Wet field conditions can present dangerous situations for athletes. A wet field is more prone to getting chewed up and compacted by athletic uses. Compaction hinders infiltration and makes it harder for grass to grow.

C o n w a y St u d e n t D e s i g n e r s :

Most of the field is less than 2% slope, and drains to the southwest corner. A 1% or less slope is recommended for most large athletic fields. The western bank edge has slopes of 5% to 25% down to the brook. A berm between the gentle slope of the field and the steep slope to the brook apparently blocks stormwater from draining into the brook, causing pooling and a wet playing surface in the southern end of the field. There is one storm drain in the parking area along the street, which outfalls to the brook. Water also pools in the depressions left from cars parking along Carpenter Street.

Spring 2015

Soils at Carpenter Street Field are fine sandy loams. Sandy loams typically drain moderately well; however, the Rippowam soil on the western half of the field is a floodplain soil with a high water table. According to the USDA, the depth to water table in Rippowam soils are anywhere from 0 to 18 inches. A high water table may limit water infiltration and therefore may lead to surface pooling. Any grading along the western edge of the field would require more in-depth analysis of the exact height of the water table.

It features a buried pipe large enough for children to climb through, a wooden bench, and a mound to run over. Those coming to Carpenter Street Field for uses other than organized sports tend to meander through the field; there is no centralized gathering place. Some may find respite on the lawn beneath a tree while others take advantage of the full sun on the bleachers. Some visitors allow their dogs to run free off-leash. Although this activity is not sanctioned it seems to be a popular site within walking distance of citizens without yards to provide exercise for their dogs.

Implications: • Given the high number of seniors living within a quarter-mile of CSF adding features may increase visits from this demographic. • Addressing the demand on the field for active recreation, the drainage and quality of grass is a priority. Adding shade will improve the spectator experience. • More active and passive recreation uses and increased public stewardship may decrease the amount of illicit behavior. • Protect trees from car parking. Provide access for emergency vehicles. • Explore safe and accessible connections to downtown, surrounding neighborhoods, and the Cheshire Rail Trail • Brook and bank remediation can improve habitat, provide floodwater storage, and allow for greater public access.

Though well used by sports teams, there is little else for a wide range of users. Minimal and uncomfortable seating, no paths within the field, and a lack of amenities for seniors makes CSF less accessible.

Some residents are discouraged by occasional littering, loitering, vandalism, fighting, and drug use at the park, which city police monitior. The high brush and trees in the northwest corner provides shade and a visual barrier. These activities are city-wide issues and have been mentioned to be concentrated within a close proximity to the north and east of CSF.

A sunny and flat field is conducive to large team sports yet the lack of shade is problematic for spectators. Members of the team sports have shared their appreciation of having a sports field so close to downtown and on the east side of Keene. They support the improvement of the field and share their willingness to be stewards of CSF.

Beaver Brook is channelized and in full sun for most of the year. The banks are steep and covered mainly in invasive vegetation. These factors reduce habitat and increase the intensity of flooding. The field is in a floodplain. A flat field with compacted soils and a potentially high-water table increases the amount of time the field is submerged. The brook is not easily accessible yet an assest to local schools as an outdoor classroom.

Carpenter Street Field: A Landscape Master Plan

Carpenter Street Field is 5-acre open space owned and maintained by Keene’s Department of Parks, Recreation, and Cemeteries. Its primary use is for large field sports. The proximity of CSF to downtown, residential neighborhoods, basketball courts, and the Cheshire Rail Trail is one of its greatest assets. The diversity of neighborhood types and public spaces provides opportunities for a large variety of users to experience open space within the densely developed edge of downtown. Connecting CSF to the Cheshire Rail Trail that bisects Keene east-west and just over the brook from CSF was the most common request on the on-line bulletin board.

NEW ADA PATH TO HARRISON ST. & DOWNTOWN

Carpenter

Carpenter Street Field is a valuable asset for the East Side Neighborhood, the Downtown Core District, and all of Keene. Active and passive recreational features draw new visitors to the park to engage in a healthy outdoor lifestyle. Seating, lighting, shade, and other amenities create a pleasant atmosphere while parents watch their children climbing up rope structures, hopping from one boulder to another, or watching the salamanders sun bathe. An improved universally-accessible path in the northwest corner passes along the brook connecting the park to Harrison Street and downtown. On the southwestern edge a 10’ wide pedestrian bridge spans the brook welcoming visitors from the Cheshire Rail Trail, basketball courts, and neighborhoods from the south.

Carpenter Street Field provides valuable ecological services. A vegetated riparian buffer and a meandering stream highlight the western edge of the park. Retaining some of the older trees and grading other parts of the bank to a more gentle slope creates an inviting area for visitors of all ages and abilities to explore. The buffer is home to a diverse array of flora and fauna and the stream has pockets for new aquatic life. The widened bank provides for additional floodwater storage.

The field is regraded at a uniform 1% slope towards the brook. A 1% slope is the maximum recommended for athletic fields. The even slope running down from east to west ensures even drainage. The field is a typical cold-zone high-quality mix of Kentucky bluegrass and perennial ryegrass. These are the grasses, installed as sod from a local sod farm, recommended for heavily-used athletic fields. The overall dimensions (430’x215’) accommodate the full needs of all the current users with additional buffer zones along the edge for team benches and fan viewing.

Organic lawn care is recommended because the entire field is in the floodplain and adjacent to the brook. Yearly maintenance should include aeration and adding compost each fall (compost spreader runs behind aerator) and overseeding in the spring and fall. The City of Keene should consider using similar organic practices city-wide where properties are in a floodplain to reduce the polluting of waterways.

The vegetated basin helps to hold sediment, filter contaminants, and infiltrate stormwater. Given the age of the pipe, installed in 1931, it should be evaluated and possibly replaced during the construction of the new field and park.

With great care, remove all invasives along bank. The Japanese knotweed (JK) requires extra attention due to the ease in which it reestablishes itself from any part of the plant. Be sure to collect all parts of the plant (roots, stems, and leaves) and dispose of properly. Proper disposal may include: incineration or drying out on an impermeable surface (e.g., asphalt, concrete). Once the invasives have been removed and the bank graded, plant an herbaceous erosion control wetland mix from New England Wetland Plants (sedges, grasses, bulrushes, and forbes) Seed at 2 times the recommended rate. Cover with a coir biodegradable erosion mat and staple in place. To plant shrubs or trees, cut an X in the mat, plant the tree or shrub, then sew the erosion mat back together. Use live staking or tublings for shrub erosion control. Apply mychorizal fungi in hole when planting. More soil testing should be done prior to planting to evaluate needs for soil amendments.

A thick coir mat (made from coconut husks) keeps soils from eroding until the vegetation fills in. It also helps in weed suppression giving the intended plants a head start for successful establishment. The coir mat may help in subduing the Japenese knotweed (erosionpollution.com).

Aitan Mizrahi

Redirecting a brook is a dynamic process and once changed the future path the brook will take is unknown. Stones (large boulders and river stones) placed along bank help maintain the new meandering shape. City officials should start a conversation with adjacent property owners to discuss the impact reshaping the brook will have on their property. It is recommended, at minimum, to explore armoring the western bank to reduce severe erosion and further slow the brook. Ideally, neighboring property owners will seize the opportunity to extend the meandering into their property. See sheet 4 for the previous path of Beaver Brook.

The buffer serves multiple ecological and aesthetic functions. Trees sequester stormwater reducing the amount of water in the soil. Vegetation helps to stabilize the bank from erosion and filters any sediments from runoff keeping the brook free of particulates. According to local ecologist Jeff Littleton, establishing the brook to its more serpentine shape and increasing the amount of diverse and native flora along the bank can have a significant positive impact improving the habitat for a diversity of fish, amphibians, reptiles, invertebrates, and birds. An increase of wildlife in the riparian buffer and the brook provides ideal places for education about ecosystem services and the benefits of supporting wildlife in urban environments. The added vegetation is a vibrant place for kids to play and explore the wonders of the outdoors. Parents can watch from the benches or lawn in the shade of existing and new trees. Paths meander through the buffer along a gentle slope providing access to the brook for all. Local students can assist in the stewardship of the brook by collecting data on the quality of water and biotic activity in the brook.

The new meandering path of the stream has many benefits. A more natural bending brook invites visitors to explore the mysteries of a brook ecosystem or sit along the path and admire the bounty of wildlife passing through. More bends in the brook slows down the speed of the water reducing erosion along the bank and creates new patches of habitat. In addition to widening the brook’s surface area, the bank is cut back (up to ~80’) accommodating floodwater storage during storms. Providing floodwater storage along the brook may reduce the frequency of the field flooding during small storms.

Improve control: Provide orientation and wayfinding with large, visible fonts. “The park layout needs to be legible.” Signs should be 54 inches off the ground or lower, so people in wheelchairs can also see them. Offer greater choice: “Everyone values options, such as passive or active recreation, sun or shade, single or multiple seating. Chairs should be movable.” Madeline Brozen, Program Manager of the UCLA Complete Streets Initiative and the Assistant Director of the Lewis Center for Regional Policy Studies, emphasized that the group older than 65 is incredibly diverse, from “not old to advanced dementia,” so they have different needs. Create a sense of security: “There should be shade but not too much so it feels enclosed.” Parks should enable “eyes on the street.” Isolated areas need good maintenance. Sidewalks should be wide and smooth. Check spaces between paved and unpaved areas to make sure there aren’t spots where a cane or wheelchair can get caught. Accessibility: If a park is a good distance from a senior facility, add benches along the way so there are place to stop. Social support: Design should facilitate interaction. Parks can feature bulletin boards, outdoor reading rooms, sculptures and fountains that help start conversations. Physical activity: Parks should also feature mile markers for encouragement. “These kinds of things are low impact, high benefit.” Exercise machines should be under shaded areas. Nature: Bring in water features, which are relaxing, beautiful, and help muffle street noise. Make sure they are wheelchair accessible. And lastly, parks should highlight natural beauty. http://www.lewis.ucla.edu/wp-content/uploads/sites/2/2015/04/Seniors-and-Parks-8-28Print_reduced.pdf

Properties adjacent to CSF, the private storage, the defunct jewelry manufacturer, and the empty lot across the brook to the southwest, should be considered for acquisition. These properties can provide additional parking, indoor recreational and gathering space, and storage for the Department of Parks and Recreation.

Local developers have expressed interest in seeing CSF become more of a destination within the east side of the city. Mr. Dugan, executive director of Monadnock Economic Development Corporation, supports the idea of a multi-use trail that connects the Ashuelot River Park with CSF through Railroad Square. Keith F.

PLANTING PLAN

NOT FOR CONSTRUCTION. PART OF A STUDENT PROJECT AND NOT BASED ON A LEGAL SURVEY.

Cool season grasses, grown from seed, take about two years to establish to mature adult stage where they can resist the most abuse. Sod is recommended to be installed over the athletic field and between the playground areas. The playground grass mix needs to tolerate more shade than the athletic field, but should still withstand heavy use.

The trees on the northern border are approximated on the plan. The walking path should be placed so as to preserve as many of them as possible. Minimize excavation over roots or avoid altogether. The shrub layer below should have the invasive plants removed and the remaining natives pruned. If required to maintain privacy from neighboring properties, mountain laurel and spicebush could then be added.

Manually remove the knotweed and other invasive plants along the bank and replace with a base of sedges, grasses, bullrushes, and forbs (New England Wetmix) to stabilize the brook bank and give a natural habitat to build from for the new downtown park. All the native species plants are selected for their ability to work in a floodplain.

Additional studies into the depth to groundwater may be advisable before proceeding with the project to confirm if additional sub-surface drainage is needed below the athletic field.

VEGETATED INFILTRATION BASIN AT OUTFALL OF UNDERGROUND PIPE 93

The City may want to consider replacing the drain from the catch basin on the east side of the property during the field construction. It drains to the brook and could be daylighted to an infiltration basin in order to filter the storm water before it enters the brook, if there is sufficient height to raise its elevation.

To attempt to preserve most of the existing trees, the grade has been sculpted around the root zones of the trees, leaving the trees on virtual â&#x20AC;&#x153;islandsâ&#x20AC;?. The box elders and red maples are highly valued for their ability to stabilize a bank and should survive the root pruning necessary to lower the bank.

The bank of the brook is excavated to provide more area for flood water in the event of flooding but it also provides for easier access to the brook edge. Extreme care must be taken when disposing of the soils containing Japanese knotweed due to its ability to propagate from minuscule pieces.

Improving the athletic field was the number one priority for the park. A regraded field will provide an even playing surface that will drain consistently.

Play features can be easy to create and from recycled materials. Bright colors and interactive elements make playing fun.

A public water fountain could help reduce use of plastic water bottles. Solar powered lamps help save on electrical costs while providing light in the evening hours for visitors to enjoy the park.

The bench is a recycled plastic that is located at other parks around the city. Bike stands provide a safe place to store bicycles while visiting the park (bike rack: commons.wikimedia. org).

Large climbing rope structures help children develop physical strength, coordination, and flexibility (playlsi.com).

A majestic fence delineates the park and field from the parking area (newenglandfence.com).

Clearly labeled garbage and recycle cans may help keep Carpenter Street Field free of litter and reduce waste (globalindustrial.com).

for seniors

Oppenheimer Park in Vancouver, Canada is located on the east side of downtown in an economically depressed neighborhood. The park has been used for many years by a variety of populations. The park was also known as the home for the Industrial Baseball League and used by a famed Japanese-Canadian baseball team. It was recently redesigned and built to accommodate marginalized and homeless populations. This progressive approach to incorporate these populations rather than evict them has been quite successful. Renovations were completed in May of 2010 and now the park is heavily used by neighbors of all ages, ethnicities, and income levels. Upgrades to the park include a new field house and washrooms, universally accessible walkways, children’s playground, sports court with a basketball hoop, horseshoe pitch, patio spaces, picnic tables and seating areas, central lawn area, trees and flowers, sub-surface drainage and a new irrigation system.

The Westmoreland Nature-Based Play Area was a pilot project for Portland Parks and Recreation (Oregon). It was part of an overall master plan prepared for Westmoreland Park in 2004, following years of flooding, creek degradation, and user groups competing for park space. The recommendations included relocating various facilities, restoring Crystal Springs Creek, eliminating the duck pond, consolidating the play area, and expanding the age groups served, modifying the casting pond, interpretive improvements near the restroom building, parking modifications, and the addition of a skate park.

In St. Petersburg, Florida (pop. 269,688 as of 2013) Azalea Park, 33 acres of recreational space, is located near a residential neighborhood, two elementary and middle schools, and a large shopping mall. The 33 acres is divided into two sections, a 15-acre park alongside an 18-acre recreation center. In 2012 the Parks and Recreation department worked with Trust for Public Land to install a Fitness Zone, a multi-generational, universally accessible outdoor gym. The Fitness Zone expands the opportunities to all citizens to practice a healthy lifestyle. The Fitness Zone is designed to accommodate individuals in wheelchairs and senior citizens and it is free. “Making it affordable makes it accessible, too,” says Paralympian Jen French. “Not everyone has the financial means to join an exercise club.”

Even though the park is used by those afflicted with addiction, other park goers feel safe due to long sight-lines and the increased number of people in the park. According to Sandy MacKeigan, head programmer at Oppenheimer Park, a full-time staff is an essential element to ensuring good cooperation.

Rounded field house: a 650 sq. ft. activity space, first aid room, and kitchen space with no blind corners Rubber playground surface: easy to keep clean, washes down with a hose, and easier to find hazardous items such as needles Sharps containers: one is located in the bathroom and another along the path between benches Lighting: provides a sense of safety after dark

According to Portland Parks and Recreation, “Nature-based play can provide important connections for children and adults to the natural environment. Playing in natural environments improves language skills and collaboration; improves imagination and creativity; supports positive social development; and enhances balance, agility, and overall health.” This project was supported with funding from a voter-approved bond measure.

The Play Area opened to the public in September 2014. It replaced an outdated playground with a nature-based playscape. The designed playscape referenced the specific characteristics of the site and its surrounding community. The process involved comprehensive public input and consensus-building process that resulted in unique play elements, which were custom-made for this park and that celebrate the community’s vision.
