Over 40 designs for revitalizing urban neighborhoodsthrough green stormwater infrastructure

PHILADELPHIA CENTER FOR ARCHITECTURE

OCTOBER 2012

Presented by:

Infill Philadelphia: Soak It Up! is a design initiative created by the Philadelphia Water Department, U.S. Environmental Protection Agency, and Community Design Collaborative to advance the next generation of green stormwater infrastructure tools and to explore how green stormwater infrastructure can revitalize neighborhoods and cities. Infill Philadelphia: Soak It Up! will continue through 2013 with a series of programs and events, including a national design competition.

To launch Infill Philadelphia: Soak It Up!, the partners hosted an exhibition at the Philadelphia Center for Architecture in October 2012. The exhibition featured over 40 green stormwater infrastructure projects from Philadelphia and other U.S. cities, including Baltimore, Detroit, Cleveland, and Pittsburgh. This booklet is a compilation of the projects on display and illustrates an impressive spectrum of what’s happening right now in this dynamic field.

Green stormwater infrastructure tools are designed to capture stormwater—rain or melting snow—runoff close to where it lands on hard surfaces in cities and help it soak into the ground or slowly enter the sewer system. In the City of Philadelphia, this ensures that polluted water does not end up in creeks and rivers—the source of our drinking water. Examples of green stormwater infrastructure tools include rain gardens, green roofs and stormwater tree trenches. On a city-wide scale and through city-wide partnerships, green stormwater infrastructure will not only help improve water quality but also improve quality of life, enhance recreational opportunities, and create more vibrant neighborhoods and business districts.

In 2011, the City of Philadelphia became a national leader for its innovative approach to cleaning up the City’s streams and rivers. Green City, Clean Waters details how we can improve the health of Philadelphia’s creeks and rivers over the next 25 years and beyond, primarily through green stormwater infrastructure investments on an incremental, block-by-block scale. By capturing stormwater runoff through green tools, we can keep excess water out of our underground sewer pipes to ensure that polluted water does not end up in our waterways. Green City, Clean Waters aims to serve as a potential model for cities across the country.

The projects in this booklet are only the beginning of a partnership that is sure to inspire the design and development of green stormwater infrastructure in Philadelphia and other cities.

ECO AMPHITHEATER

A variety of site improvements were designed to maximize accessibility and usability of the grounds. Street calming strategies were employed along bustling Easton Road using stormwater gardens and �ow through planters to increase pedestrian safety.

The main grounds were carved into a gradually sloping eco amphitheater for community performances while the stage doubles as a rain water retention cistern to prevent run-o­ from entering the Sandy Run waterway and provide landscaping water during dry seasons. The area around the stage will serve as a gateway to the park and a new interpretive trail planned along the creek where interactive exhibits will educate the public on the importance of stormwater management and the natural creek ecosystem. This new porous, ADA compliant interpretive trail makes the existing township park accessible to all members of the public. The introduction of bioswales at the edge of the parking lot and along the perimeter of the dog park work to reduce incidental pollution from reaching Sandy Run Creek.

EXISTING SITE

Bequeathed to Abington Township, the historic Grove Park House is located along the Sandy Run Creek between the main thoroughfare of Willow Grove, Easton Road, and Grove Park. BAU Architecture worked with the Township to envision the incorporation of the house and its property elegantly into the existing township park.

GROVE PARK HOUSE

The initial goal was to carve out a public space for community and cultural events while also generating a destination to increase pedestrian access and tra�c to the nearby main business district. The existing historic house was converted into a community arts and education center which can utilize the new eco amphitheater in its programming along with the public and other arts organizations. Between the community center and amphitheater lie a series of healing gardens and a vegetated labyrinth designed to o­er the public a place to unwind and re�ect on the natural beauty found within the park.

Wissahickon Valley Watershed Association Sand Seepage Wetland Stormwater BMP

T his project consists of a woodland trail placed overtop of a gravity sewer paralleling the Wissahickon Creek. �e trail

was in poor condition due to stormwater discharge from an approximately 30-acre drainage area which was also eroding a channel between the receiving stream and the pipe outfall.

�e approach used to solve these problems and improve stormwater quality and quantity was an innovate ecological engineering technique called a ‘sand seepage wetland.’ �is approach involved

covering the trail with a 3-foot deep layer of coarse sand •amended with 20% (by volume) shredded hardwood, building a boulder and cobble riffle grade control across the •eroding channel that delivers the stormwater to the Wissahickon Creek, and planting the side slopes of the sand seepage bed in native plants. •

�e boulder and cobble riffle grade control restricts discharge to the Wissahickon during peak runoff periods, storing the water behind the sand seepage trail, which increases the water

surface area and enhances existing wetland water quality treatment and quantity attenuation.

�e mechanism for the water quality treatment is filtration through the carbon-rich sand filter media (sand trail with 20% shredded hardwood) as well as enhancement of natural wetland and floodplain treatment through runoff detention. As the peak discharge passes, water stored behind the sand berm and the boulder and cobble riffle grade control is able to find its way into the receiving stream over a period of 24 to 72 hours. �e sand berm presents a firmer and cleaner substrate for hikers.

�e hydrology of the wetland floodplain forest is improved, with supplemental benefits to the plant community, including suppression of non-native invasive species. �e positive environmental stewardship effect of this project on the surrounding suburban community cannot be overstated. Similar projects that have been studied resulted in an order of magnitude reduction in peak discharge, and reductions of total suspended sediment, total nitrogen, and total phosphorus.

Project Details Drainage area to BMP is approximately 30 acres• Riffle grade control sized for conveyance of the 10-year storm discharge (approximately 65 CFS)• Sized to provide quality treatment for a 1.5-inch precipitation event• Maximum storage volume is the 25-year storm discharge• Designed and permitted in 2010, constructed in January and February 2011• Design and construction cost: $79,000 (approximately three dollars per square foot)•

Birdsall Services Group worked closely with Philadelphia Water Department personnel to design and develop a prototype infiltration unit associated with a water and sewer project on Sepviva Street. The actual unit was designed to provide collection

of stormwater along the curb edge at points associated with tree pits, thereby providing, collection, storage and infiltration. Birdsall worked with the prefabrication manufacturer and the contractor to develop and install the units as a trial. The units

were intended to be used in sequence with other storage systems such as trenches, and help to promote healthy tree growth by directing stormwater to the root growth areas. directing stormwater to the root growth areas.

The issues at hand

What Not to Do!!!One often overlooked area in urban redevelopment is the role of demolition. One of the first steps in urban renewal projects for blighted neighborhoods is to demolish abandoned properties. However, there is very little information known about the existing soil conditions prior to demolition, the practice of the demolition itself, and then the subsequent backfilling of soil into the former building envelope. In many instances, the resulting vacant lot sits for a period of years and acts as a sort of unmanaged Green Infrastructure (GI) until redevelopment commences. In coordination with the US EPA Office of Research and Development National Risk Management Research Laboratory (ORD-NRMRL), USEPA Region 5, and the Cuyahoga County Land Reutilization Corporation (CCLRC), prototyped Green Demolition specifications that would improve the outcome of demolition with a vacant lot that could be used many different purposes, including redevelopment. Detailed soil investigations were conducted on five lots in the city of Cleveland, Ohio pre- and post-demolition to determine their soil properties and how soils were to the process of demolition, and better understand the sources and nature of backfill soils

In many of our major cities, populations have beensteadily declining since the 1950’s. One result ofpopulation decline and the foreclosure crisis is a glut ofabandoned homes throughout Cleveland OH. Theseabandoned homes were both an eyesore and also a place where criminal activities were occurring. The City ofCleveland and Cuyahoga County Land ReutilizationCorporation created a set of processes to clear thedisposition of vacant homes, schedule demolition, and ensure that the vacant lot is properly stabilized. However,if the demolition is not carried out properly, much debrisand poor soil cover render the vacant lot as just anotherpiece of impervious surface. We examine the demolitionprocess to see how these activities can be guided by newexpectations (i.e., green demolition specifications) carriedout to yield vacant lots that can be used for stormwatermanagement, redevelopment, pocket parks, amongother productive land uses.

• Demolition activities for five abandoned homes within one neighborhood were observed.

• Soil physical and chemical properties were measured pre demolition .

• Homes were completely demolished and all debris was removed from the property.

• Backfilling activities were observed; soil analysis of the backfill materials was conducted.

This investigation covered two areas; the quantification of the soil conditions prior to demolition and the process of filling in the former foundation with imported fill material and topsoil. We found a high degree ofvariability in the actual process of demolition, as well as a wide range of soil materials thatwere brought in as fill. Additionally, there aremethods of placing both fill material andtopsoil which would be more mindful ofcompaction and create a better environment for the establishment of turfgrass and/or landscaped vegetation for these properties. We believe that it is possible tocreate a “Green Demolition” protocol thatcreates GI for every newly demolished lot.

Above: The physical act of

demolition impacts both

the target and adjacent lots.

Right: In the new paradigm, all debris must be removed prior to any backfilling activities.

Materials and Methods

Overview

Abstract

B. Actual backfill material that the contractor has imported to the site. This material consists of lacustrinesilts and clays (in addition to construction debris) and has a very low permeability. By using this type ofbackfill material, the capacity for stormwater to reachthe native sandy soils is severely impeded, reducing itspotential as Green Infrastructure.

Clockwise from Upper Left: The basement foundation must be completely removed prior to backfilling; the subgrade soils are graded level; then subgrade soil is scarified prior to the placement of appropriate topsoil; the topsoil is next spread in such a manner so that the machinery will not re-compact the surface.

BA. Soil pit adjacent to a demolished residence. Thenative soil were formed from aeolian sand depositsand is both extremely coarse in texture and rapid inpermeability. The native soil has enormouscapacity to serve as Green Infrastructure inattenuating stormwater runoff.

We recommend that pr ior to any type of Green Infrastructure being considered, a thorough assessment of the soi ls and landscape must f i rst be conducted. Histor ical ly, the level of basel ine information for urban soi ls i s pr imit ive, i f any information is avai lable at al l . In addit ion to the dearth of soi ls data, a typical geotechnical invest igation is focused only on viabi l i ty for soi l stabi l i ty vis-à-vis bui lding construction, and are thereby deficient in both the scale and detai l of information required to make responsible planning decis ions for Green Infrastructure (GI) projects. We developed an urban soi l assessment protocol to guide detai led soi l invest igations on vacant lots and city-owned parks in Cleveland, Cincinnati OH, and Omaha NE to determine soi l and landscape suitabil i ty for GI . This invest igation encompassed the physical and chemical characterization of soi l propert ies as i t relates to mit igating impacts from a Combined Sewer System.

At a time when post-industrial US cities struggle to mitigate combined sewer overflows (CSO) as a part of long-term control plans negotiated or settled under a Clean Water Act (CWA 1972) consent decree, these same cities are also rapidly accumulating vacant properties due to legacy blight, and unprecedented foreclosure on residential, commercial, and industrial properties. These properties find their way into the inventory of city-run land banks where the disposition of vacant land can be stabilized, the title cleared, demolition and site closure can be carried out, at which point properties await re-purposing. Since there is a concomitant need for detention of stormwater runoff and an availability of land mass, this arrangement suggests opportunities for this land to be used as a sink for excess stormwater runoff, urban agriculture, green space, expansion of city parks, among other uses that foster social-equity, economic stabilization, and environmental quality in traditionally underserved locations.

While these urban soils are quite variable compared to a natural setting, trends can be found that will allow for the creation of an accurate urban soils map. This information is of critical importance for the end user, in this case City Planners and Engineers, who are accountable to taxpayers and regulatory agencies for successful management of municipal issues such as stormwater and CSO management.

There are stark differences between what has been traditionally (and minimally ) done with Soil Taxonomy and Soil Survey work in an urban setting. Furthermore, the level of information required for adequate land use planning is also beyond the capabilities of a traditional geotechnical investigation. In contemporary urban land management, it is critical to know the depth of fill material, the nature of the fill material, and the underlying native soil.

We suggest a set of methods and experiences as a protocol for urban soil survey and hydraulic assessment work. It is our hope that this work will stimulate dialogue between the soil scientist and the land use planners and designers. Carrying out an effort such as this takes an interdisciplinary team to fully understand the various connections amongst soils, stormwater, and human impacts on managed ecosystems.

The figure above shows subsoil hydraulic conductivity (a limiting factor for infiltration performance) values for native sub-areas at each sampled location. Hydraulic conductivity test depths ranged from 60 to 180 cm (2 to 6 ft).

These soil profiles exhibit a typical range of soils found during this investigation. The photo on the leftillustrates the contact between the fill material from both the house construction and subsequent demolition, and glaciofluvial parent material. The middle photo shows the contact with aeolian dune sand deposits and the photo on the right illustrates a residual parent material. These transitions are all present between 1 and 2 meters (3-6 ft).

100 OPPORTUNITIES A Philadelphia neighborhood-based moving park appears in one residential street, lingers for a day or two before disappearing to another, and leaves you wishing for its return. Was it real? Can imagination and education encourage the emergence of green stormwater infrastructure in older, ultra-urban environments? Understanding how the surface expression of these technologies impacts and possibly transforms a neighborhood is also critical to its acceptance. As a continuously temporary quarter-acre park, MOVING PARK delights residents and enables them to momentarily inhabit and actually see the potential of urban greening and inspired place-making.

“Its greatest strength is that it physically expresses potential.”

THE RADIANUniversity of Pennsylvania | 3925 Walnut Street, Philadelphia PA

Located on the 3900 block of Walnut Street, the Radian is a student housing-complex composed of 150 plus apartments, 500 beds and 40,000 square feet of retail space. A retail plinth along Walnut Street is made up of a series of storefronts that intentionally resurrect the street’s former silhouette by playfully undulating the vertical scale. Above it rises the residential tower, sharing space with Penn’s other high-rises just a few block away.

In combination, the Radian green roofs, comprised largely of drought tolerant succulent plants, manage approximately 250,000 gallons of stormwater per year and through evapotranspiration, the vegetation helps to cool the rooftop temperature. These benefits, among others, help to offset the effects of urbanization. This is one of the few sites in Philadelphia, where green roofs are visible to pedestrians and patrons of a private business and, serve as both an amenity and as a stormwater management device.

Erdy McHenry Architecture | Roofmeadow

The Radian is situated within the view of a McDonalds, a few upscale restaurants, a wide greenspace, and a cluster of high-rise student housing complexes. It is built with contested space in mind: it neither belongs to the medley of retail spaces that mark West Philadelphia nor to the flat academic buildings that are signature of University City. It gracefully blurs the line between these two frictional landscapes, while simultaneously upgrading the language of both.

The Radian is a student apartment community in University City. The residential mass of the structure, elevated over the base, allows for daylight and striking neighborhood views to penetrate the windows of the Radian. The angular massing, named after the ratio between the length of an arc and its radius, enables the afternoon sun to reach the narrow street to the north. The building features both a green roof and a prefabricated rain screen facade.

The project is a unique example of using green roofs to receive and treat runoff from adjacent rooftop areas. Four green roof areas, totaling 12,200 square feet manage runoff from 28,600 square feet, absorbing more than a quarter million gallons and preventing it from entering the City’s sewer system. Impervious roof and pavement areas drain onto adjacent green roofs. The green roofs, ranging in thickness from 4 to 6 inches, are designed to efficiently percolate the received runoff and slow its progress as it flows through granular soil toward the roof drains. This maximizes moisture uptake by soil and plants and runoff rate and volume are substantially reduced. On two of the roofs manifolds and/or stone channels are used to transition the runoff from adjacent roof areas. None of the green roof areas have permanent irrigation. Since being installed in 2008, the green roofs have functioned as designed, without water erosion or upsets resulting from excessive moisture. All of the roofs have developed dense ground covers of Sedum, supplemented in some instances by planters with colorful perennials. In two areas, planters are used to intercept, slow, and filter runoff.

The deployment of green areas to intercept stormwater runoff is believed to delay the runoff peak by about 50 minutes reducing contribution to flow rates in the receiving storm sewer.

The project also includes two underground stormwater detention facilities that intercept runoff from other impervious surfaces. The design garnered a Stormwater Best Management Practices Award from the Philadelphia Water Department in 2007.

The roof visible from the restaurant peaks in June with multiple Sedum species and Dianthus blooming in pinks and yellow. In the fall as the weather cools, the green roof areas display rich reds, oranges, and yellows. The green roof by the restaurant is punctuated with planters which provide a shock of bright color. Other green roof planters show interest throughout the growing season with species like Allium and Delosperma blooming in the spring, Geranium and Dianthus blooming throughout the summer, and the purple Asters showing their stuff in the fall.

As the plant communities mature the media becomes increasingly bioactive and the green roof areas are able to evolve into biodiverse ecosystems. With the passage of time the green roof areas become more efficient at managing stormwater.

A roof cover workhorse Sedum that provides excellent coverage and stormwater absorption. In the spring the foliage emerges like little green beads and presents white flowers in the summer. In the fall the foliage turns a brilliant red.

The distinct serrated edges of the foliage help with identification of this slow growing, mounding succulent. Bright yellow flowers emerge in August. A roof cover plant that is will remain evergreen throughout a mild Philadelphia winter.

Sedum FloriferumNative to Europe, occurring in dry, grassy habitats often in the mountains. In the spring when the blooms shoot skyward, this perennial is a radiant show stopper at the Radian.

Dianthus CarthusianorumA thirsty and sturdy roof cover whose dark pink flowers appear late in the summer season off of tender green shoots. Roots extend 4” deep making this an excellent plant for thin compliance green roofs. Spurium is easily established from cuttings.

Sedum spurium ‘Summer Glory’

In combination, the Radian green roofs, comprised largely of drought tolerant succulent plants, manage approximately 250,000 gallons of stormwater per year and through evapotranspiration, the vegetation helps to cool the rooftop temperature. These benefits, among others, help to offset the effects of urbanization. This is one of the few sites in Philadelphia, where green roofs are visible to pedestrians and patrons of a private business and, serve as both an amenity and as a stormwater management device. 9

Conclusion: Adapt Stormwater BMPs for multiple functionality.

Example: Collect and concentrate rainwater to support a water

intensive activity—local food production. Practiced since ancient times, gardening is a classic part of the Urban Vernacular

Harvested rainwater preferred over “city” water due to chlorine residual

Focusing harvested rainwater for irrigation reduces stress on City water system

Reduced Food Miles and better utilization of Land and Leisure Time

Community Gardens are proven to strengthen neighborhoods, an oasis in a food desert

Incremental reduction in peak runoff as individual systems are brought online

A Case for Merging Stormwater

Management and Agriculture in the Urban Environment

Project Location: Metuchen, New Jersey Project Client: Schaffer Residence

Rain is a gift and a renewable resource, not a nuisance. Perhaps this has been a fundamental flaw in modern urban

infrastructure design practice.

The proposed stormwater management structure is intended to provide groundwater recharge, peak flow attenuation, and urban agricultural use for piped roof runoff. Stormwater runoff is introduced into a structure similar to a rain garden, however, instead of native plants in a pit, a raised bed food production garden is installed. The balance of the garden area is covered with ordinary turf grass. The structure will also function with a buried liner typical of most rain gardens (or without in heavy clay soils), or on a concrete pad with proper re-enforcement of the perimeter berm. This structure can be used to direct overflow to a stable outlet condition.

It is important to note that as a point of stormwater concentration, an overflow must be included in the installation. In addition, monitoring after rain events is crucial for the health of many garden plants, which are minimally tolerant to extended flood conditions. For example, excessive watering can cause splitting in tomatoes.

By introducing stormwater runoff into a discharge point adjacent to the plantings, the water will be treated within the soil matrix; this is as opposed to rain barrels that do not offer this treatment. In addition, the deliberate concentration of stormwater will cause a localized groundwater mounding effect, which will reduce the need for irrigation. As a structure sized for the anticipated Water Quality Storm, it will have a greater capacity to attenuate runoff from these storms. The project is “accessible” to the average gardener for cost, skill set, and tooling. A perimeter sod berm is constructed utilizing existing turf stripped from the future raised bed footprints. This berm is raised to accommodate a design storm from the contributing roof (s), creating supplemental runoff attenuation as well as a “key” for rodent fencing.

Typical Urban BMP Implementation Constraints

Constraint Effect

Roofs and hardscape cover a large portion of Urban Areas.

Unchecked peak storm water flows from Impervious surfaces.

Anthropogenic Soils tend to be poorly draining due to compaction and composition.

Most BMPs are unsuitable for an urban environment because they rely on positive drainage through infiltration.

Urban Infrastructure exhibits extreme inertia—a resistance to change from legacy.

Cost to implement new technologies; mone-tary, physical, and cultural are enormous.

Limited “yard space” in Urban Areas reduces number of candidate sites for Surface BMPs.

Implementation often limited to existing parks or urban renewal (eminent domain).

Limited space devoted to people, cars, and buildings, BMPs rip the fabric of the street.

Urban BMPs are typically buried tanks, ~5 to 10 times the cost compared to surface BMPs.

Traditional BMP maintenance is echewed by the public; responsibility = culpability.

BMPs in danger of disrepair; malfunctions and dumping can cause localized flooding.

Rain barrels are a great start but mostly undersized for all but the smallest storms.

Constant draining necessary to achieve desired attenuation of small storm runoff.

Construction method used for this project:

Survey the potential site to ensure good gravity drainage from the downspouts to the discharge point.

Plan the proposed garden area. Compute the storage volume required for the de-sign storm and the resulting berm height needed.

Install liner system, if desired. Presence of a heavy clay soil may make a liner un-necessary.

Set up a level line around the perimeter of the proposed garden area.

Strip lawn sod into oblong “bricks” and lay upside to form the perimeter berm. Select one of the following options:

Dig out the infiltration trench and perform a percolation test, target drain time is 72 hours; or

Install extended downspout to drain directly into the turf garden paths, sta-bilize outlet with gravel as needed (preferred method).

Install planting beds and high water overflow. Clean downspout and discharge as necessary. Perimeter sod wall under construction with yellow level string The site during installation, it is possible to build a BMP by hand Turf grass recovers quickly and armors the berm Pepper plants thrive with little watering

As urban areas densify, land cost increases. Buildings and structures are adapted for multiple functions as a result. Stormwater Best Management Practice (BMP) design has not yet caught up to this adaptation.

CARPENTER SQUAREA NEW MIXED-USE DEVELOPMENT AT S 17TH AND CARPENTER STREETS, PHILADELPHIA, PA

The site for the proposed Carpenter Square development is currently a vacant lot owned by the Philadelphia Redevelopment Authority (PRA). For the last 10+ years the site has remained one of the largest underutilized parcels in the Southwest Center City neighborhood. The PRA awarded the project to Carpenter Square, LP through a competitive RFP process in late 2011. The development team’s proposal differentiated itself by focusing on modern design that integrates sustainable design strategies and a program that includes a mix of housing, commercial, and public open space.

Carpenter Square includes 11 townhomes, 6 condos, corner commercial, and a public plaza. The project integrates features such as passive ventilation, a high-performance building envelope, low flow plumbing fixtures, high-efficiency energy management systems, and Energy Star lighting and appliances. To manage stormwater runoff, the project incorporates over 9,800 SF of green roofs, several flow-through planters, over 6,400 SF of permeable paving, and numerous stormwater planters. A majority of new vegetation will consist of native, non-irrigated, drought-tolerant plants. In addition to LEED for Homes certification, the team is seeking certification for the entire project through the LEED for Neighborhood Development program. With its modern design, mixed-use amenities, and extensive green features, Carpenter Square is poised as a model for future sustainable redevelopment in Philadelphia.

Ingersoll Park

Ingersoll Park is the result of a unique 3-way public/private partnership between a private non-profit developer, (Community Ventures), Philadelphia Department of Parks and Recreation, and the Philadelphia Water Department. The development integrates a new major public open space, management of offsite stormwater, and new affordable sales homes, to revitalize a deteriorated urban neighborhood.

The project will result in:

> Redevelopment of a full-block vacant site in Lower North Philadelphia that will be a catalyst for neighborhood investment.

> A new .64-acre Philadelphia Department of Parks and Recreation public park in an area lacking public open space.

> Incorporation into the park of a Philadelphia Water Department stormwater management rain garden that will absorb runoff from 2 acres of surrounding public streets and support PWD’s “Green City, Clean Waters” program

> For-sale affordable housing facing the park that provides “eyes and ears” on the park.

The site at 16th and Master Street was acquired by the City in 1968. Originally planned for open space, the parcel remained vacant for over 40 years. The Philadelphia “Green 2015” plan identified Lower North Philadelphia as an area undeserved by public parks. Community Ventures saw the opportunity for a landmark development that would provide much needed public open space, address PWD’s public right-of-way stormwater management goals, and create a focal point and amenity for a new residential development facing the park. The new park and rain garden faces 16th Street, while the 10 new townhouses, accessed by a permeable paved driveway provide an attractive backdrop for the open space, as well as security for the park. Cost of the park and rain garden is $1m. Construction cost for the residential development is $2.6 m. Construction will begin spring 2013.

Cafe Olam Like many of the other studies, the Jewish Population Survey of

Greater Philadelphia found that the "under 40" subset is

experiencing a decrease in connection to the Jewish

community. This same demographic, however, does find and

create community in nontraditional settings. They are spending

time, money, and social capital in bars, restaurants, coffee shops,

shows, events, and educational & civically oriented programs.

Of this demographic, the vast majority are not committed

to significant Jewish identity. If the Jewish community seeks to

engage and retain this demographic in Jewish life, we need to

reorient our points of communal gathering to reflect these ongoing

demographic shifts. Cafe Olam is the answer, and your

support in building this community is necessary.

DESIGN:

Underutilized impervious areas in parking lots provide an excellent opportunity for stormwater management. If feasible, these retrofits can improve water quality, reduce the volume of water leaving the site, provide educational benefits, and improve upon the aesthetics of the large impervious area. Using green stormwater infrastructure techniques that utilize soils, vegetation, and infiltration for stormwater management, the design includes a series of bioswales, bioretention, and a tree trench with a subsurface storage bed that provides a multi-faceted system to manage runoff the parking lot. The removal of pavement and the planting of trees also provide site greening and shading, which help to mitigate urban heat island effects. The design maximizes the runoff volume capture of smaller storms at the site and provides a comprehensive demonstration of urban stormwater techniques.

The project was constructed in the summer of 2010 and includes a large bioretention area in the parking lot adjacent to Delaware Avenue, a vegetated bioswale in the center of the parking lot, and a small bioswale that leads to a larger subsurface infiltration tree trench along North DuPont Street. Approximately 31,000 square feet of parking lot, or 0.7 acres, are managed by these systems. During very large storm events, overflow from these systems are directed to the existing sewer. Because of these quantifiable improvements, the City of Wilmington has granted ACME a reduction in their stormwater fee.

ENVIRONMENTAL:

Greening the Greens at the First Tee of PittsburghThe First Tee of Pittsburgh is a golf course located at the top of the Panther Hollow watershed. To mitigate runoff generated by the compacted lawn, modest infiltration berms were designed along the contours to impede the flow of runoff and allow it to infiltrate along the hillside. During heavy storms, the runoff will safely overflow to existing drainage features (inlets and swales) without causing unintended erosion. Located within the existing rough, the retentive grading and enhanced landscape provides stormwater benefit, while causing little interference to the players.

Skinny Schenley DriveThe PPC is enthusiastically pursuing funding to “skinny” a portion of Schenley Drive that meanders through the Park. A vegetated buffer and porous pavement recreational path, underlain by a subsurface infiltration bed, fits within the current cartway and shoulders to manage runoff generated by the remaining road and existing sidewalks. Where infiltration is not feasible in the lower portions of the watershed, the stormwater bed will slow the movement of runoff for slow-release of treated water to the Phipps Run tributary. A skinny Schenley Drive will alleviate erosive streambank conditions caused by large impervious surfaces, and ameliorate flooding conditions on Carnegie Mellon’s campus. The new street design will also accommodate its multiple users and safely connect pedestrians and bicyclists to Squirrel Hill and Oakland, as well as the Park itself.

Restoring the Panther Hollow Watershed with Green Infrastructure

*Not to Scale

DESIGN + SITE PLAN: In 2010, Meliora Design led a multi-firm team in the preparation of a restoration plan to restore the natural hydrologic regime of the Panther Hollow watershed through the implementation of green infrastructure. After identifying and prioritizing GI interventions, two pilot projects were selected in the upper reaches of the watershed to manage runoff where it is generated. The pilot projects, designed by Meliora, Andropogon and Cosmos Technologies are awaiting construction in 2013. Beacon Street GI RetrofitThe design along Beacon Street converts an eroded and compacted lawn hillside into a stormwater feature that manages runoff from the right-of-way, creates valuable habitat through the establishment of a native meadow, enhances connectivity between the Park and Squirrel Hill neighborhood, and improves park aesthetics. New inlets convey road runoff into two infiltration trenches where it then percolates into the existing soils. During large storm events, the runoff overflows to level spreaders that evenly disperse the excess stormwater onto the meadow.

SITE CONTEXT: The Pittsburgh Parks Conservancy (PPC) has embarked on a visionary effort to restore the hydrologic and ecological health of the Panther Hollow Watershed, located within Schenley Park and the neighborhoods of Oakland and Squirrel Hill. Characterized by a human lake at the lower end of an urbanized watershed, the tributary streams that feed the watershed and lake have been “beheaded”, buried, and diverted to the combined sewer system, in addition to the watershed’s upper drainage area. Such impacts have led to a significant loss of groundwater recharge and baseflow, causing the upper reaches of the streams to be dry, eroded channels, and the Lake water quality to suffer. At the same time, the stream channels suffer from flashy, excessive flows during rain events which have led to their continued erosion with much sediment finding its way into Panther Hollow Lake.

Led by Rothschild Doyno Collaborative, the Meliora Team, in collaboration with the PPC, engaged community stakeholders and residents during the green infrastructure planning process to ensure the plan reflects their needs and overall vision for the Park. Particularly, the designs: • Improve connectivity of the Park to adjacent neighborhoods • Enhance park and neighborhood aesthetics • Generate outdoor educational opportunities • Increase awareness of “wild” landscapes • Provide traffic calming and improves pedestrian safety in a high-traffic area (Skinny Schenley)

VAN SCIVER ELEMENTARY SCHOOL RAIN GARDENS AT SADDLER’S WOODSDESIGN:

The stormwater management design conveys stormwater runoff away from the parking lot and drop-off loop in front of the school, through two trench drains, onto attractive stone splash blocks, and into a series of vegetated swales and rain gardens. This series of berms and gentle landscape depressions slow and disperse water allowing it to absorb into the modified onsite soils and recharge groundwater through infiltration. The soils and native vegetation both filter runoff to improve water quality. The two rain gardens in front of the school building were designed with a continuous slope to ensure there would not be standing water in front of or around the school for any significant length of time, while the two rain gardens behind the school are intended to pond up to 6-inches of water before overflowing to the adjacent woodlands through a level spreader. In between the rain gardens, berms with large stone blocks allow access to the system for education and maintenance, while also slowing the velocity of water moving through the system. The planting palette included all native plants that are salt-tolerant due to the nature of the contributing drainage area and that are able to survive in variable moisture conditions. The design team worked closely with the Delaware Riverkeeper Network and the School Board to make this system as safe and low-maintenance as possible, while providing an attractive, functional amenity.

In 2008, NKCDC, and the Pennsylvania Horticultural Society (PHS) met with the Mayor’s Office of Sustainability to identify a 20 acre site in Fishtown/Kensington as a location to highlight sustainable infrastructure and education. The Big Green Block (BGB) represents the application of innovative green in-frastructure improvements to a new LEED Platinum high school, an existing recreation center, and the public spaces in and around these two areas. This project acts as a gateway to comprehensive community revitalization: connecting fractured communities, increasing engagement, leadership and social capital, leveraging community assets, history and culture, and tying into city and regional strategies. This site furthered these goals by increasing part-

nerships, establishing new resources, and expanding reach to new residents and communities. Education and partnership has been critical to the implementation and suc-cess of these infrastructure improvements. Each partner brings expertise, re-sources, and a creative approach to addressing the needs of the site. The Pennsylvania Horticultural Society, the Philadelphia Water Department, Phila-delphia Department of Parks and Recreation, Mural Arts Program and NKCDC worked to develop a master plan for the block identifying more than 16 locations and $2,000,000 in green infrastructure actions.

Site improvements include infiltration gardens, stormwater tree trenches, wa-ter education murals, new play areas and greening. The site manages ap-proximately 90% of its total stormwater. Phase II is expected to capture an-other 5%. Over the past 3 years, more than $46 million in green infrastructure improvements have been completed through the various partners. NKCDC's Sustainable 19125 program, the Mural Arts Program's interpretive murals, PWD's Green Ambassador program, Kensington CAPA's Green Team, and PHS all provide educational programming and awareness around the site which contribute to the community's understanding, protection, main-tenance, and valuing of these public spaces.

As part of the redevelopment of the Philadelphia Navy Yard into an urban cor-porate center, Pennoni was responsible for the design of one mile of public in-frastructure to support 1.5M SF of private development. The infrastructuredesign incorporated one mile of green stormwater infrastructure into a newroadway network. The project to redevelop the former brownfield was jointlyfunded by the Philadelphia Water Department and Liberty Property Trust.

When the U.S. Navy substantially closed the Navy Yard, ownership was trans-ferred to the Philadelphia Industrial Development Corporation (PIDC). LibertyProperty Trust served as the agent for PIDC in the brownfield redevelopment.The infrastructure project includes the design and construction of one mile ofnew roads and several miles of new utility infrastructure. The roads were de-signed as “Green Streets” in accordance with the sustainability goals of themaster plan.

The design incorporated two different green stormwater details based on thestreet type defined in the master plan: stormwater planters and tree trenches.The landscape design was developed to blend the green stormwater compo-nents with the adjacent site development. Utilities (water, storm, sanitary, tele-phone/data, electric, gas) were located to facilitate the installation of greenstormwater infrastructure.

North Third Street is unique. A mostly residential

corridor with active neighborhood groups, a successful

community development corporation, and a potential

appetite for additional housing, the corridor lacks

public and private green space, and a buffer from

adjacent industrial uses. The relative proximity of

North Third Street to Temple University and several

modes of public transportation make it a potential site

for a variety of housing development - mixed income

owner-occupied developments and rental housing

units may be viable along the corridor and in the

adjacent neighborhood.

The Pennsylvania Horticultural Society

identified a synergy in the potential for new housing

construction in this area and the Philadelphia Water

Department’s desire to establish development models

that innovatively comply with current stormwater

regulations. Environmentally responsible “green”

methods of managing stormwater could be a source

of inspiration and even funding for a proposed North

Third Street greenway and nearby development.

Neighborhood open spaces, sidewalks, streets, and

houses should be built so that they manage stormwater

on site, potentially redirecting money that would

otherwise be spent on underground infrastructure.

with Meliora Environmental Design, is bounded by

Berks, Third, Norris, and Fourth Streets in North

Philadelphia. Although the project does repsond to

specific site conditions, it should be considered a

model, or better, a set of suggested concepts, for

housing and open space development in an urban

environment. Our proposals for this site are intended

to imagine new urban development possibilities that

consider stormwater management strategies as

generative concepts. We envision housing, water,

and open space working together.

Sidewalk planters absorb the �rst �ush of stormwater from adjacent streets

Stormwater Cells also absorb the �rst �ush of stormwater from streets.

The Trays absorb stormwater over�ow from the streetside and tidal �ux from the riverside.

Tidal wetlands create shallow water habitat at the river’s edge.

Moving inland, wetland plants take on a more formal arrangement. A framework for an aesthetically driven massing of plants, the Trays highlight the colors/textures of di�erent species, while receiving the river’s highest tides and stormwater over�ow from the street.

The existing park reveals little variation in material and vegetation. A walk through the proposed park exposes the viewer to a diverse plant and material palette that emphasizes the various roles that water plays on the site.

VIEW AT PIER: The pier reaches out into the river, providing the widest prospect of the river and the Ben Franklin Bridge. With ample and varied seating, and a lawn terrace, it is an inviting perch from which to enjoy the views. The terminus is cantilevered to minimize the impacts to the existing shoreline.

Penn Treaty Park occupies the site where William Penn and the Lenni Lenape tribes forged a treaty in 1682 promising peaceful coexistence between their peoples. As a historically signi�cant site, it has su�ered from relative obscurity. In its current context the park is at the center of a growing movement to revitalize the Central Delaware Riverfront, and bring this territory back into the public realm as a recreational, economic and ecological amenity.

Located within the 100-year �ood plain, the site’s 6-foot tidal �uctuation could foster a unique habitat were it not for the concrete bulkheads and stone rip-rap constricting the river’s edge. Additionally, the site is located near two CSO outfall pipes that compromise the delicate riparian ecosystem. The Interstate 95 overpass and several lanes of tra�c on Delaware Avenue make public access di�cult.

The proposed master plan restores 3 acres of tidal and non-tidal riparian wetlands and the riparian edge, improving river function, quality, and �ood plain storage capacity. The design is carbon-neutral and requires zero municipal water use. Maximization of pervious surfaces, usage of native plant species, water reuse for restrooms and water features, composting toilets, and on-site renewable energy generation help meet these goals. The park not only in�ltrates rainwater that falls within the site boundaries but it also intercepts stormwater runo� from approximately 30 acres of adjacent impervious surface. Integral to the success of the design are new walking paths, bike lanes, and increased public transit, all of which improve public access to the new park.

SECTIONS THROUGH SOFT EDGE OF SITE: The shoreline is recon�gured to allow the tidal �ow of the Delaware River to reach up into the park; reconnecting the �oodplain to the river,

improving the ecological value of the riparian zone, and creating valuable tidal wetland habitat.

VIEW OF FOUNTIAN AND GLASS CANOPY: The photovoltaic-out�tted glass canopy provides a �exible space for both casual and spontaneous activity, café seating, and large-scale events and festivals. The interactive fountain engages children while also providing a sound barrier from I-95 and adjacent Delaware Avenue.

VIEW AT BIKE PATH: At the heart of the park is a generous path and seat-wall. Serving as both a connector and a destination, the seatwall path bor-ders the lawn, and o�ers opportunities to people-watch, rest from activities, and enjoy the view.

VIEW AT STREET: This urban threshold is meant to be transporting while also feeling immensely accessible from all sides. Each of the planted cells receives stormwater runo� from the adjacent street, and showcases an abstracted and distilled native plant palette.

VIEW AT PEBBLE BEACH: Nestled within the wetlands, a small gravel beach would allow for toe-dipping, rock skipping and kayak launching. There was strong community support for a place to launch small, human-powered water craft.

The renovated Office Building achieved LEED Platinum, scoring the highest number of points at the time of completion for a LEED project in Pennsylvania.

Two key objectives governed the project: eliminate fossil fuel consumption and greenhouse gas emissions, and reduce water usage and stormwater runoff.

Friends CenterLeading the way towards cleaner water and a greener c it y

R I S I N G T O A C I T Y W I D E C H A L L E N G E

Prior to the project’s implementation, Friends Center discharged 58,400,000 gallons of untreated stormwater runoff into the Schuylkill River on an annual basis, contributing to a citywide problem of Combined Sewage Overflow (CSO). Through the renovation, 42% of the site was made permeable, greatly reducing stormwater runoff.

O V E R V I E W O F P R O J E C T

The Friends Center renovation evolved from a modest capital improvements project into a Quaker witness for environmental sustainability. The project entailed the restoration of the historic 1856-Meetinghouse and renovation of a four-story 1975-office building, which occupy a dense 1.26-acre urban site in center city Philadelphia. Through considerable stakeholder involvement and education, two key objectives emerged as guiding principles for the project—eliminate fossil fuel consumption and greenhouse gas emissions, and reduce water usage and stormwater runoff.

An initial green planning charrette, funded by the KresgeFoundation, identified several potential stormwater managementstrategies, including a rain garden in the rear courtyard, a vegetatedroof, tree trenches along the site to replenish the local aquiferthrough infiltration, and a constructed wetland and livingmachine to provide natural on-site sewage and wastewatertreatment. Strategies ultimately implemented include the green roof, tree pits and a rain water collection and reuse system. The rain garden was dismissed since it would have disrupted the original layout of the historic site. The constructed wetland and living machine were not implemented as the priority of the project became focused on reducing water usage and runoff.

P R A C T I C A L S T R A T E G I E SA 9,327-SF vegetated roof was installed atop a new ENERGY STAR® roof on the Office Building. The green roof retains 90% of stormwater runoff and purifies the remaining 10% not absorbed by vegetation or soil. The vegetation comprises eight varieties of Sedum that require weeding twice a year.

G R E E N R O O F

Rain water is collected from the roof of the Meetinghouse and stored in six 660-gallon cisterns in the basement of the Meetinghouse, harvesting an estimated 20,000 gallons of stormwater per month. The reclaimed water is filtered and purified, then recycled in the Office Building’s toilets. This system significantly reduces Friends Center’s potable waterusage, also equating to a substantial reduction in water bills.

Kansas City’s Green Solutions Pilot Project

EngineeringKansas City, MO is using green infrastructure to reduce Combined Sewer Overflows in a 100-acre urban neighborhood. This innovative pilot project is reducing stormwater flows to the sewers while also helping renew a neighborhood.

EcologyThe project includes more than 150 rain gardens, bioretention gardens, cascades, curb extension planters, below grade storage systems and permeable sidewalks. The project also planted new street trees. These green solutions help restore ecological function to the urban landscape while creating sustainable stormwater management solutions.

CreativityPublic involvement was integrated into the design process. As a result of community input, stormwater improvements were blended with neighborhood enhancements to rebuild streets and sidewalks, slow traffic and create attractive landscaping.
