Beverly & Schaeffer Park Improvements Presented by: Justin Mendinsky, P.E Alex Greenly, E.I.T.
PRESENTATION OUTLINE • Beverly Park Improvements • Schaeffer Park Improvements • MS4 Review • Permit Requirements • Pollutant Reduction Plan Requirements • Proposed Stormwater Management BMPs
BEVERLY PARK - Existing Conditions • Located at the intersection of Beverly Rd. & Westerly Rd. • Approximately 1.5 acre parcel • Borough owned park • Offers a grassy setting with playground equipment, benches, and basketball court
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).

SCHAEFFER PARK - Existing Conditions • Located at the intersection of N. 28 th 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 - 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 of 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: o New playground equipment o Gaga pit o Basketball courts o New restrooms o Swing set o Pavilion • 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).

S tormwater 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 of 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% Chesapeake Bay (2011) Sediment transported after Total Nitrogen 3% 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 – Source: https://www.fairfaxcounty.gov/publicworks/stormwater/dead-run-stream-restoration
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 Required Sediment Load Reduction: 145,097.9 lbs/yr • 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) – Percent of Total Sediment Load Sediment Project Description Reduction Reduction (lbs/yr) (%) 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%
Beverly Park Stormwater Management Facilities Three Infiltration Based Stormwater Management BMPs 1. Shallow Infiltration Bed 2. Underground Detention & Infiltration Basin 3. Small Rain Garden at Low Point 4. Impervious Surface Removal (Existing Basketball Court) 1 2 3 Proposed Sediment Reduction: 255,506 lbs/yr
Schaeffer Park Stormwater Management Facility One Infiltration Based Stormwater Management BMP 1. Infiltration Bed or Rain Garden T.B.D. 2. Impervious Cover Removal (Demolished School Building) 2 1 Proposed Sediment Reduction: 27,205 lbs/yr
