Introduction Overview

Whitman

Green City, Clean Waters is the Philadelphia Water Department’s (PWD) 25-year plan for protecting and enhancing the city’s watersheds by managing stormwater with green infrastructure. PWD and the Pennsylvania Department of Environmental Protection (PADEP) signed a Consent Order and Agreement (COA) based on this Long Term Control Plan Update (LTCPU) for Philadelphia’s combined sewer system.

Located in South Philadelphia, Whitman is bounded by Snyder Avenue to the north, 6th Street to the west, Oregon Avenue to the south, and Swanson Street to the east. The 195-acre neighborhood is predominately residential and was selected as an area of opportunity because of potential opportunities to manage stormwater on school and park sites and from the adjacent I-95 expressway.

In order to achieve the scale of implementation committed to in the COA, PWD is now shifting towards identification of stormwater management opportunities in study areas of various sizes. Concentrated or interconnected investment in stormwater management improvements will not only facilitate compliance with the COA but allow PWD to leverage opportunities for coordination and cost sharing. One scale of study area defined by PWD is the Area of Opportunity, and PWD is currently working on an Area of Opportunity Analysis (AOA) for each of those study areas, including the Whitman neighborhood.

Through the planning process, alternatives were developed to help the Philadelphia Water Department achieve the following goals: • Identify cost effective green stormwater infrastructure (GSI) projects that maximize stormwater management potential • Align with city-wide and community planning efforts and set PWD up for meaningful engagement with stakeholders in the future • Identify a combination of GSI solutions that manage public and private runoff on public parcels, as well as provide green street opportunities • Prioritize GSI in highly trafficked areas to increase the visibility of stormwater management practices and Green City, Clean Waters

I-95, Burke Playground, and Murphy Rec Center (from top) present opportunities to implement highly visible stormwater improvement projects and manage signficant areas of the Whitman Neighborhood.

Environmental Conditions Ground cover composition, topography, and surface water flow direction provide a basis for understanding the most viable locations to capture the greatest amount of stormwater.

Drainage Patterns Stormwater generally drains to the southeastern corner of the neighborhood (towards the 500-year floodplain). On a micro-scale, stormwater flows to adjacent streets and continues as sheet flow to nearby inlets.

Land Cover Land cover in the Whitman neighborhood can be classified into five major categories: travelway, rooftop impervious, ground level impervious, and pervious. Ground level impervious surfaces represent the largest land cover category and are largely comprised of sidewalks, parking, and concrete pads. Pervious ground cover generally consists of lawn, roadway median plantings, and bare earth. Larger areas of pervious cover exist at parks and schools throughout the Whitman neighborhood.

Floodplain With the exception of the northwestern corner, the Whitman neighborhood falls within the 500-year floodplain. The 500-year floodplain is an area with a 0.2% annual chance of flooding where average depths are less than one foot.

Utilities Identifying opportunities for green stormwater infrastructure must take into account the presence of above and below ground utilities to understand opportunities for connecting to existing infrastructure while avoiding other infrastructure. A combined sewer system with pipes carrying both sanitary wastewater and stormwater currently serves the Whitman neighborhood. Sewer flow is treated at the Southeast Wastewater Treatment Plant on dry days. During storm events, water may be released directly into the Delaware River without treatment. Within the Whitman neighborhood, water and wastewater utilities are generally located within street rights-of-way. Sewer sizes vary, ranging from 4 inches to 48 inches in diameter. Detailed utility surveys will be necessary for the implementation of any green stormwater infrastructure projects. Additional surveys have been completed for Mifflin Square, Taggart School, and Murphy Recreation Center. These surveys are included in Appendix D.

Current Whitman Neighborhood Stormwater Management Initiatives Within the Whitman neighborhood, PWD plans to implement green streets at:

One site planned for green street implementation includes Sharswood School.

• Our Lady of Mt. Carmel and George Sharswood Schools Stormwater trenches along: -- Wolf Street (from Second Street to Third Street) -- Ritner Street (from Second Street to Third Street) -- Second Street (from Wolf Street to West Ritner Street) • St. Monica Manor Stormwater trenches along: -- Fourth Street (from Porter Street to Vollmer Street) -- Shunk Street (from Fourth Street to Galloway Street) • Galloway Street (from Shunk Street to Porter Street) Tree trenches to manage a 8,606 SF drainage area Additionally, Taggart School has been identified as a Green2015 site. As a part of this initiative, impervious surfaces will be removed to help meet the city’s goal of adding 500 acres of new publicly accessible green space by 2015.

Taggart School, a Green2015 site, presents an opportunity to implement an SMP that is highly visible and manages a large area of impervious surfaces.

Circulation and Hubs Major circulation routes and activity hubs are heavily trafficked locations that could provide opportunities to engage and educate the neighborhood’s 9,6001 residents and visitors with highly visible green stormwater infrastructure. Prioritizing projects in these areas increases the visibility of stormwater management practices and Green City, Clean Waters.

Circulation Snyder Avenue and Oregon Avenue serve as the neighborhood’s main eastwest travel routes. Major north-south vehicular and pedestrian travel routes include 2nd Street and 4th Street and provide access to recreational and institutional hubs within the neighborhood. Residents and visitors typically enter the Whitman neighborhood at the following vehicular and pedestrian gateways:

Hubs Park and recreation hubs include Mifflin Square, Weinberg Park, Burke Playground, and Murphy Recreation Center. Murphy Recreation Center includes a basketball court, pool, sports field, and ballfields and offers recreational, art, and computer classes. Institutional hubs include the Whitman Library, Our Lady of Mount Carmel Church, and Sharswood and Taggart Schools. Both School District of Philadelphia schools are grades K–8. Along Oregon Avenue, commercial hubs include both chain and local retail shops, financial and medical offices, eateries, and service-oriented retail. Such uses make this area a highly traveled pedestrian hub. Vehicular commercial hubs include Snyder Plaza South and Aldi.

• Front Street and Snyder Avenue • 2nd Street and Snyder Avenue • 4th Street and Snyder Avenue • Front Street and Oregon Avenue • 2nd Street and Oregon Avenue • 4th Street and Oregon Avenue The Whitman neighborhood is served by several SEPTA bus routes, including Routes 7, 47, 57, and 79. Designated bike facilities are currently limited to on-street facilities along Snyder Avenue. While not designated as bike routes, 5th and 6th Streets are bicycle friendly routes and are identified in the 2012 Pedestrian and Bicycle Plan as routes where mid-block and intersection improvements are recommended to make the streets more attractive to cyclists and calm vehicular traffic.

From top: Oregon Avenue serves as a primary pedestrian and commerical corridor.

GSI Projects Feasibility Through the delineation process, the feasibility of managing individual drainage areas with SMPs was evaluated. Feasible drainage areas generally included public schools, parks, vacant parcels (with no structures), I-95, and large, privately owned parcels over 5,000 sf1. Rights-of-way with few utility conflicts were also identified as drainage areas where SMPs are feasible. Throughout the Whitman Neighborhood, the feasibility of SMP implementation is limited due to large areas with impervious surfaces, small parcels, limited space for stormwater storage, and conflicts with utilities. Initial identification of potential projects found limited options as many are not cost effective or have minimal stormwater management potential. The following factors were used to assess feasibility and identify potential projects. • Loading Ratios - Initial analysis of potential stormwater improvement projects identified limited space both on site and on adjacent lands (public rights-of-way and alleys) as a major barrier to implementation. Locating SMPs in yards, alleyways, and streets was determined to be not viable for most privately-owned parcels because there is insufficient space to achieve required loading ratios (5:1 on privately owned lands and 10:1 on publicly owned lands). Options such as rooftop disconnection were considered but also found to be infeasible due to insufficient space on site, in alleys, and at the end of blocks to achieve a 5:1 loading ratio. • Utility Conflicts - Both residential and commercial properties throughout the Whitman neighborhood are largely impervious (buildings, sidewalks, concrete pads, etc.), limiting the majority of stormwater improvement opportunities to public rights-of-way. Within the rights-of-way, there are high probabilities of utility conflicts, and costs associated with utility relocation are prohibitive. Laterals that connect each rowhome to mains mean a large number of utility conflicts along most residential blocks, making many stormwater management options difficult to implement.

• Fragmented Ownership - Privately owned lands encompass 87 percent of parcels within the Whitman neighborhood. The majority of these parcels are small residential parcels around 850 sf in size and are owned by individuals. As described in the following section, cost efficiency is reached on projects that manage drainage areas at least 5,000 sf in size. Implementing SMPs on residential blocks with lots under 5,000 sf is difficult due to both the number of individual owners and small parcels. • Cost Effective Projects - In limited areas, nearby alleys, vacant lots, and larger front and side yards provide the space necessary to implement green stormwater infrastructure while meeting the required loading ratios. While loading ratios can be met, these projects are typically not cost effective as they are not located adjacent to another project and manage under 5,000 sf. To achieve cost efficiency, the drainage area being managed must be at least 5,000 sf or there must be multiple projects in close proximity to each other.

Whitman Neighborhood Feasibility

Areas within the Whitman Neighborhood that are potentially or not currently feasible should not be fully disregarded, as they could become feasible sites for stormwater management improvements in the future if: • more innovative methods of working around existing utilities are found to simplify construction • the financial barriers to small projects can be overcome, or if small projects could be aggregated to achieve cost savings • loading ratio requirements are relaxed

Per PWD Site Analysis Procedure, drainage areas under 5,000 SF were not considered feasible because PWD does not consider them cost-effective. The exception is multiple projects proposed in close proximity to one another. 1

Potential Stormwater Improvement Projects – Rights-of-Way RIGHTS-OF-WAY Opportunities for green stormwater infrastructure on residential properties are constrained due to large areas of impervious surface, lack of available space, and conflicts with utilities. Throughout the residential areas of the Whitman neighborhood, publicly owned rights-of-way present the greatest potential for implementing infrastructure improvements. Residential alleys were also considered but proved to have limited stormwater management potential due to space constraints. Analysis of rights-of-way identified three major typologies:

Typical Whitman Residential Block with Tree Trenches Tree Trench Drainage Area Rights-of-way with very few conflicts Rights-of-way with few utility conflicts Rights-of-way with many utility conflicts

• Rights-of-way with very few conflicts • Rights-of-way with few utility conflicts • Rights-of-way with many utility conflicts Rights-of-way with very few conflicts present the greatest potential for both SMP options and capacity. Streets with more conflicts are limited in capacity to manage and implement stormwater management improvements. Based on the right-of-way utility conflict analysis, the three greatest opportunities to implement green stormwater infrastructure on residential streets are: • Tree trenches on streets with few utility conflicts Tree trenches present the greatest potential for greening and stormwater management capacity, and they are highly visible. • Bumpouts on streets with few utility conflicts Bumpouts have a lower capacity for stormwater management than continuous tree trenches, but they also provide benefits associated with traffic calming, greening, and visibility. • Subsurface storage below sidewalks or cartways (depending on the location of utilities) Subsurface storage has a high capacity for stormwater management but lacks benefits associated with greening and visible stormwater management strategies.

Potential Stormwater Improvement Projects

RIGHTS-OF-WAY STORMWATER IMPROVEMENT PROJECTS Based on the rights-of-way analysis, potential stormwater infrastructure improvements were identified for the following streets: • Swanson Street • Front Street • 2nd Street • 4th Street These streets represent rights-of-way with few utility conflicts. With the exception of Swanson Street, from Ritner Street to Wolf Street, tree trenches were identified as stormwater infrastructure improvements that would be both highly visible and effective stormwater management projects. Tree trenches were sized to manage entire rights-of-way and were located on one side to avoid conflicts with overhead power lines and reduce impacts. Due to overhead power lines, subsurface storage was identified as the most feasible SMP along Swanson, from Ritner Street to Wolf Street.

Large rights-of-way along Swanson Street present an opportunity to manage stormwater 6 from adjacent private properties.

Potential Stormwater Improvement Projects – Site Specific Potential stormwater management practices on the following publicly-owned parcels include options to manage both public and private runoff. These parcels are generally large tracts with minimal building coverage and large open spaces. Preliminary identification of stormwater management practices followed the following guidelines: • Existing structures, parking spaces, and play areas should remain.

Both approaches considered projects such as rain gardens, tree trenches, and subsurface storage beds to manage on-site impervious surfaces and/or stormwater from adjacent properties. The potential stormwater improvement projects for each site are not mutually exclusive, and in many cases, multiple infrastructure improvements could be implemented to maximize greened acres and management of public and private runoff.

• Retrofitted areas should accommodate and enhance existing uses. • Stormwater management practices (SMPs) should require minimal storm sewer construction and regrading. • Vegetated SMPs are preferred over subsurface controls, where feasible, to maximize visibility of stormwater management practices. • Controls should manage both on- and off-site impervious areas and manage the first inch of runoff. • Loading area ratios should be a maximum of 10:1. Based on these principles and initial analysis of the Whitman neighborhood, the following strategies for maximizing stormwater potential were explored for each site. • Managing the Site and Adjacent Streets: Managing stormwater on-site from impervious surfaces such as roofs, sidewalks, and play courts. In addition to on-site management, this strategy also identifies the potential for managing adjacent rights-of-way. • Maximum Stormwater Capture: Similar to the previous approach, this strategy identifies the potential for managing on-site and adjacent rights-of-way, but it expands off-site management to include the maximum feasible catchment area given site capacity.

Constraints include: • Shade: Lack of sunlight below decking limits opportunities for vegetated SMPs.

FRONT

Similar to rooftop disconnection, the 388,667 sf highway could be disconnected. Downspouts could be directed to large subsurface beds beneath the elevated roadway and between parking areas. The beds could further be expanded to manage surrounding rightsof-way and private properties. Detailed subsurface geotechnical studies would be necessary to confirm infiltration would not damage pier foundations. The elevation change also presents an opportunity to daylight stormwater management at eye level.

SNYDER

At the Whitman neighborhood’s eastern edge, I-95 presents an opportunity to implement a high impact project visible to travelers along the interstate and through the Whitman neighborhood. The eight lane highway is elevated on piers with large paved lots below for parking and for car and material storage. Inlets collect highway runoff, which flows down pipes mounted on piers to ground level, where it is discharged or continues underground.

Zoning Zoning regulations govern land use and aid in determining the compatibility of green stormwater infrastructure with allowable uses. Approximately 67 percent of land within the Whitman neighborhood is zoned as residential single-dwelling attached (RSA-5). The residential single-dwelling attached (RSA-5) is primarily intended to accommodate attached and semidetached houses on individual lots. The eastern boundary is zoned as general industrial (I-2) and represents 25 percent of the area. General industrial accommodates light industrial uses, moderate-impact uses, and employment activities such as manufacturing, distribution, processing, industrial parks, and other activities that may generate noise, odor, vibration, after hours activities, or traffic impacts well beyond property lines. Areas zoned special purpose district - parks and open space (SP-PO-A) represent 7 percent of lands within the area. This zoning helps preserve and protect lands set aside for park and open space use. This zoning denotes active parks and open space. The remaining 1 percent of land is zoned commercial. Located throughout the neighborhood and along Oregon Avenue, corner store commercial (CMX-1) and neighborhood commercial mixed-use districts (CMX-2) are intended to accommodate neighborhood-serving retail and service uses.

Susceptibility to Change Susceptibility to change broadly indicates the likelihood that an area will change in the near future. Change can include new development on previously undeveloped land, redevelopment, change of use, or intensification of use.

Vacancy Most susceptible Least susceptible

1 0

vacant occupied

The susceptibility to change map was created using a GIS overlay analysis of three factors:

Parcel Size Most susceptible Least susceptible

1 0

non-residential parcels over 1 acre all other parcels

• Ownership • Vacancy • Parcel Size For each factor, every parcel within the Whitman neighborhood received a value of 0 or 1, where 0 is the least susceptible to change and 1 is the most susceptible to change. For each parcel, all factors were then added together with equal weights to produce a final susceptibility score. Susceptibility scores were divided into 3 categories: areas with high susceptibility to change, areas with medium susceptibility to change, and areas with low susceptibility to change. A description of the values assigned for each of the four factors is described below. Ownership Most susceptible 1 private, non-residential parcels Least susceptible 0 private, residential parcels publicly-owned parcels

Appendix B - Key Planning Initiatives Key Planning Initiatives The following key planning initiatives recommend improvements that impact land use in the Whitman neighborhood. A summary of recommendations from these initiatives, their time frame, their likelihood of implementation, and the implementing agencies is provided below. • Philadelphia Pedestrian and Bicycle Plan. The first citywide pedestrian plan and update to the 2000 citywide Bicycle Network Plan identifies strategies and specific recommendations to increase the number of people walking and bicycling in the city by improving the safety, connectivity, convenience, and attractiveness of the pedestrian and bicycle networks. • Green2015. The Green2015 initiative outlines a strategy for how to meet the city’s goal of adding 500 acres of new publicly accessible green space to the city by 2015.

Whitman AOA Stormwater Improvement Plan

The city’s comprehensive plan, Philadelphia2035, provides a broad citywide vision but does not include specific recommendations for the Whitman neighborhood. Based on the plan’s broad recommendations, district plans for every neighborhood in Philadelphia will be prepared in the next few years. When complete, the South District Plan will include recommendations based on major ideas from the Philadelphia2035 on the neighborhood level.

Pedestrian and Bicycle Plan The Pedestrian and Bicycle Plan identifies recommendations to increase the number of people walking and bicycling in the City through safety improvements, connectivity, convenience, and attractiveness of pedestrian and bicycle networks. The plan outlines five goals related to safety, encouragement, the public realm, connectivity, and recognition. 2012 Pedestrian and Bicycle Plan. Philadelphia City Planning Commission, Philadelphia, PA

A School District of Philadelphia site, Taggart School is largely covered by impervious surfaces including parking, a playground, and the school building. A small landscaped area exists to the north of the building. The site is generally flat and drains towards the parking lot in the northwest corner.
