Great Falls Nike Field Stormwater Enhancements 2012

  1. 1. Public Information MeetingInstallation of Athletic Field Lighting, Synthetic Turf and RelatedStormwater Enhancements on Rectangular Field #4at Great Falls Nike ParkJuly 18, 2012
  2. 2. IntroductionsDranesville District Supervisor’s Office John Foust, SupervisorDranesville District Park Authority Board Member Kevin FayDepartment of Public Works and Environmental Services Craig Carinci, Director Stormwater Planning Fred Rose, Chief Watershed Planning and Assessment Emma Gutzler, Ecologist, Stormwater PlanningFairfax County Public Schools Steve NicholsonFairfax County Park Authority David Bowden, Director Planning & Development Division John Lehman, Manager, Project Management Branch Deb Garris, Manager, Synthetic Turf Branch
  3. 3. Meeting Agenda Presentation: Park AuthorityOverview of Project to Include Athletic Field Lighting Technology andPerformance Standards and Synthetic Turf Field Development Presentation: Department of Public Works andEnvironmental Services (DPWES)Overview of Proposed Stormwater Enhancement Measures Informal Discussions
  4. 4. Funding Partnerships Great Falls Nike #4 is a partnership betweenGreat Falls Lacrosse and Department ofNeighborhood and Community Services andPark Authority.

  7. 7.  Increased Playability Estimated to increase playing capacity by 62% inconjunction with the addition of lights, when comparedto natural turf. Increases capacity on lighted existingfield sites lessening the need for constructing additionalfields. Increased Durability Reduces field closure due to overuse, allowing fields toremain open for the length of the season. Eliminatesdivots, bald spots, and uneven terrain of rigorously usednatural turf fields.Why Synthetic Turf?
  8. 8. Why Synthetic Turf? Lower Maintenance Costs Requires no mowing, fertilizing, pesticides or re-seeding.Regular maintenance includes grooming and debrisremoval.(continued)
  9. 9. Quality Synthetic turf systems provide water quality improvement byreducing phosphorus runoff to nearby streams andtributaries. The synthetic turf system acts as a filter, capturing smallamounts of physical and chemical contaminants. Natural grass athletic fields often do not have healthy standsof grass due to over-use. The lack of healthy stands of grassincreases the amount of sediment present instormwater runoff. Synthetic turf fields do not require the use of fertilizer andother chemicals that ultimately enter the natural stormwatersystem.Stormwater Management Benefits of Synthetic Turf

  11. 11. Enhanced Stormwater Retention - Stone Galleries Provides water quality andvolume reduction beyond thePFM requirements Total Phosphorus Removal 1.2lbs/year Goal is to retain / infiltrate the100 YR storm volume
  12. 12. Piney Branch at Great Falls Nike Park Drainage area ofapproximately 36 acres Current project focuseson 3.5 acres Working with ParkAuthority andForestville Elementaryon other opportunities

  14. 14. Stone Galleries High measuredinfiltration rates Captures water from2.68 acres Four linear stonegalleries underlying theturf field One along thesouthern endline Temporary storageallowing infiltration
  15. 15. Grassy Swale Parallel along thewestern sideline High measuredinfiltration rates Treats stormwaterfrom 0.40 acre Reduces runoff, totalphosphorus and totalnitrogen
  16. 16. Organic Soil Amendments Around the field Deeply tilled inorganic compost Restores soilporosity andincreasesinfiltrationInsert close up photo ofcompost (in hands??)Insert photo of soilamendments beingincorporated
  17. 17. Reforestation Native trees andshrubs on 0.44 acre Encourages infiltration Intercepts and filtersrunoff Provides habitat
  18. 18. Enhanced Stormwater Accomplishments Additional retentionof stormwater runofffrom field #4 Reduced runoff =reduced pollutants

  21. 21. Installing Infill Materials
  22. 22. Proposed Synthetic Turf Infill Options “FutrFill – TPE (Thermo Plastic Elastomer)derived from an environmentally inertmaterial process and Silica Sand Mixture “PureFill” – Cork which is a totally organicproduct, 100% recyclable with no wasteby‐products harvested from cork oaktrees every nine years and Silica SandMixture
