BEVERLY PARK - Existing Conditions

BEVERLY PARK IMPROVEMENTS

Design Goals & Considerations

• Improve esthetics with plantings and natural features
• Rehabilitate existing gardens
• Provide adult recreational features, (benches, pergola swing, etc..)
• Install walking path
• Incorporate grassy open space
• Maintain existing playground equipment and memorial fountain
• Reduce the amount of stormwater runoff leaving the site
• Decrease potential of roadway flooding on Beverly Road
• Achieve pollutant load reduction proposed in the Borough’s

Chesapeake Bay Pollutant Reduction Plan (MS4 Requirement).

BEVERLY PARK – Conceptual Layout Rendering

• Located at the intersection of N. 28th St. & Walnut St.
• Prior location of Schaeffer Elementary School
• Approximately 3.5 acre parcel
• Borough owned park
• Offers a grassy field and baseball diamond

SCHAEFFER PARK - Existing Conditions

SCHAEFFER PARK - CONCEPT TIMELINE

 2006-2016: Old Schaeffer School building sat vacant falling into disrepair. Residents in the area reported safety concerns as well as reports of trespassing, squatting, theft , and vandalism.

• 2015: Borough offers to share the cost of demolition of the abandoned school with the School

District with the vision of constructing a new municipal community park at the location.  2015: Building was fenced by the Borough in fall over safety concerns.  2016: Building condemned in the spring of 2016.  2016: Borough solicited a qualified contractor to demo the building in fall of 2016.  2016: 2018 PADEP General Permit (MS4) regulations announced requiring quantitative pollutant load reductions in municipal stormwater.  2017: Demolition Contract was completed in the early 2017.  2017: Draft Pollutant Reduction Plan submitted to DEP and advertised in July 2017 for 30-day comment period.  2017: Borough produces three (3) unique conceptual layout sketches for the future development

• f Schaeffer Park to achieve load reduction proposed in the PRP.

 2017: Town Hall meeting was held on March 9, 2017 to gain community input on concept drawings and the amenities they wanted to see in the park.  2018: The vision of this building this park is consistent with the general goals and objectives of the Comp Plan to maintain and enhance the public and recreational facilities and infrastructure.  2018: Revisions made to the conceptual sketches based on community feedback.  2018: The current design has incorporated many of the community’s concerns as well as what Borough Council believes is good for the entire community.

SCHAEFFER PARK IMPROVEMENTS – Design Goals

• Rehabilitate existing athletic fields.
• Construct a new playground featuring:
• Provide ADA access & parking improvements.
• Maximize open green space for public use.
• Reduce the amount of stormwater runoff leaving the site.
• Achieve pollutant load reduction proposed in the Borough’s

Chesapeake Bay Pollutant Reduction Plan (MS4 Requirement).

• New playground equipment
• Gaga pit
• Basketball courts
• New restrooms
• Swing set
• Pavilion

Stormwater Management - MS4

(Municipal Separate Storm Sewer System)

The system with the “Urbanized Area” that collects, conveys, or manages stormwater

• Inlets
• Pipes
• Swales
• Detention BMPs
• Infiltration BMPs
• Water Quality BMPs
• Outfalls

MS4 Permit

• NPDES (National Pollutant Discharge Elimination System)

– Provides the Borough authorization to discharge stormwater to local waterways

• General Permit (PAG-13) for Stormwater Discharges from Small

Municipal Separate Storm Sewer Systems (MS4s) – Water Quality Permit – Reduce quantity of runoff – Increase quality of runoff – Reduce stream impairments – Improve local watershed health – Limit impact on downstream receiving waters (Chesapeake Bay) – Unfunded mandate!

MS4 Permit Requirements

• Pollutant Reduction Measures (PRM)

Activities undertaken to identify and control pollutant discharge to local impaired waterways.

• Chesapeake Bay Pollutant

Reduction Plan (CBPRP)

Requires a reduction in the amount

• f sediment and nutrients transported

to the Chesapeake Bay. Must be completed within 5 years of approval.

Pollutant Required Load Reduction Sediment 10% Total Phosporus 5% Total Nitrogen 3%

Chesapeake Bay (2011)

Sediment transported after Hurricane Irene & T.S. Lee

Improving Local Stormwater Quality – BMPs

(Best Management Practices)

• Riparian Buffer Projects

– Reduce rate of runoff – Provide plant uptake of pollutants – Capture sediment before entering streams – Reduce thermal impacts – Establish habitat – Removal of invasive plant species

Improving Local Stormwater Quality – BMPs

(Best Management Practices)

• Stream Restoration Projects

– Reduce streambank erosion – Floodplain reconnection – Improve habitat – Limit Sediment & Nutrient Load

Improving Local Stormwater Quality – BMPs

(Best Management Practices)

• Infiltration BMPs

– Reduce volume of runoff – Groundwater recharge – Natural filtration of pollutants – Reduce thermal impacts – Reduce flood impacts – Ideal for urban settings

Chesapeake Bay Plan Preparation

• Borough Conducted Comprehensive Project Selection Evaluation

Based on the Following Criteria:

– Property Access (Municipally-owned property preferred) – Site suitability / BMP Type Evaluation – Achievable Pollutant Load Reduction – Cost & Constructability (Best “Bang” for the buck) Project Description

Sediment Load Reduction (lbs/yr) Percent of Total Sediment Reduction (%)

Willow Park Stream Improvement Project 51,612.0 35.6% Beverly Park Impervious Area Reduction and BMP Project 55,505.9 38.3% Schaeffer Park Impervious Area Reduction and BMP Project 27,205.1 18.7% Street Sweeping 7,991.9 5.5% Green Infrastructure Projects (Various) 2,586.1 1.8% Storm Sewer Cleaning / Solids Removal 1,072.4 0.7%

Total Proposed Sediment Load Reduction 145,973.4 101%

• Required Sediment Load Reduction: 145,097.9 lbs/yr
