  1. Public Input Workshop #2 August 9, 2012

  2. Agenda • 6:30 – Welcome, introductions • 6:35 – Where we last left you • 6:40 – Park Baseline Characterization Report • 6:50 – Swim Beach Design Characteristics • 6:55 – Draft Master Plan • 7:15 – Project Impacts and Potential Mitigation • 7:25 – Q & A • 7:40 – Small Group Work • 8:10 – Spokesperson Shares • 8:25 – Next Steps • 8:30 – Meeting Adjourns

  3. Ground Rules Please!!!!! • Listen actively • No one person dominates • Stay on topic • No personal attacks • Stay on time/schedule • Don’t make assumptions/assume good will • Hold Questions till Q & A

  4. Where we last left you in July, 2011

  5. Capital Lake Swim Beach

  6. 2010 PAR Plan Public Feedback

  7. Our Commitments • Post materials from 1st public meeting on web page • Learn everything we could about the lake • Develop a master plan concept utilizing what we heard at the 7/14/11 public meeting • Share master plan concept with you in advance of the meeting

  8. Ward Lake ParkBaseline Characteristic Report

  9. Environmental/Cultural Baseline Inventory • Topographic Survey • Shoreline & Underwater Reconnaissance • Wetland Delineation/Report • Baseline Water Quality Report • Geotechnical Investigation • Tree Survey

  10. Upland Habitat • Pasture grass • Few trees

  11. Wetlands • Lake fringe wetland • Category III • 0.44 acres • Extends to depth of 6.6 feet • 80-foot buffer (0.9 acres)

  12. Shoreline • Whole Lake • Park Site

  13. Shoreline - Lake • Landscape and bulkheads common • Natural shoreline areas also common • 39 docks • Abundant large wood • Fragrant water lily

  14. Shoreline – Park Site • Natural shoreline • 268 trees on site, primarily along shoreline slope • Fragrant water lily • Sparse Nuttall’s waterweed • Submerged large wood • Steep slope • Organic detritus substrate

  15. Water Quality • Water clarity • Phosphorous • Chlorophyll • Trophic Index • Algae blooms • PCBs in fish tissue Water Clarity Trend (Source: Thurston County) Summer average Total Phosphorous concentrations (Source: Thurston County)

  16. Water Quality • Water clarity • Phosphorous • Chlorophyll • Trophic Index • Algae blooms • PCBs in fish tissue Summer average lake surface Chlorophyll a (Source: Thurston County) Ward Lake Summer average Trophic Index (Source: Thurston County)

  17. Water Quality • Water clarity • Phosphorous • Chlorophyll • Trophic Index • Algae blooms • PCBs in fish tissue • In recent years there has been an increase in documented toxic blue-green algae blooms occurring in lakes within Washington State. • There appears to have been an increasing occurrence of late winter/early spring algae blooms in Ward Lake • Lake may be shifting from dominance by green algae to blue-green • This year was a game changer

  18. Water Quality • Water clarity • Phosphorous • Trophic Index • Chlorophyll • Algae blooms • PCBs in fish tissue Source: Seiders et al. (2008). U = The analyte was not detected at or above the reported value. J = The analyte was positively identified. The associated numerical result is an estimate.

  19. Water Quality Impacts Three Areas of Interest • Stormwater (Upland) • Bacteria (Shoreline and Lake Bed) • Phosphorus and Algae Blooms

  20. Stormwater • Primary concern is stormwater from roadways and parking lots • All stormwater will be treated through infiltration (e.g., porous pavement and filtration strips), THE best technique for removal of pollutants

  21. Stormwater • No stormwater from the upland area will drain toward Ward Lake • Stormwater from the pedestrian trail will be treated and detained at predevelopment rates and be discharged toward the lake

  22. Bacteria • Based on King County’s monitoring of swimming beaches, no bacteria problems are expected

  23. Phosphorus and Algae Blooms • Phosphorus (P) is typically the key ingredient in promoting algae blooms in lakes; although not necessarily the case for toxic blooms • P input from the site will be controlled through better vegetation management in the upland area and through use of artificial turf at the shore • Less P should be exported than under typical residential development • Infiltration and movement through the ground is very effective for P removal • The park is not expected to result in increased P or lead to more or extended algae blooms

  24. Fish Species, Rare Plants, Priority Habitats • Stocked with rainbow trout and kokanee (WDFW) • Cutthroat trout, largemouth bass, bullhead, yellow perch • Nuttall’s waterweed • Three State Priority Habitats: • Riparian habitat • Freshwater wetlands and deepwater • Snags and logs • No priority species or features in upland area

  25. Beach Safety Standards U. S. Army Corps of Engineers

  26. Beach Safety • Excellent Design • Purposeful Management

  27. Excellent Design • Continous & Consistent Slope • 1:12 or less • Depth & DepthMarkings • Life line • Outside Markers • BottomMakeup • Floats

  28. Excellent Design • Life Saving Equipment • Life Jacket Station • Water Turbidity • Water Quality

  29. Purposeful Management • Guarded vs. Unguarded • Monitoring Safe Conditions • Signage • Regulating Human Behavior • Safe Use • No pets

  30. Master Plan Concept

  31. Park Program Elements • Distance & Vegetative Screening • Parking • Soccer Field / Open Field Play • Pre-School & School Play Facilities • Small Plaza • Picnic Facilities • Restroom/Storage Building • ADA Compliant Routes • Lake Swim Beach & Support Facilities • Maintenance Support Facilities
