1 LID Evaluation and Analysis University Surface Parking Lot Janelle Bonn Janice Greenwood, P.E. COMMITMENT & INTEGRITY DRIVE RESULTS
2 Project Regulatory Background Site is located on urban waterfront property within the Metro Bay Region in Providence, Rhode Island subject to Coastal Resources Management Council (CRMC) Urban Coastal Greenway Policy (UCG) CRMC UCG provide development projects the option to: Follow Coastal Buffer Setback Regulations; or Use the UCG option, which clarifies and streamlines regulatory process for urban coastal development and creates greater flexibility in meeting CRMC requirements COMMITMENT & INTEGRITY DRIVE RESULTS
3 Urban Coastal Greenway Policy Purpose Encourages redevelopment of the Metro Bay Region shoreline in order to promote reuse of abandoned or underutilized Brownfield sites; Discourages over-development of Rhode Island s rural and suburban green spaces; and Protects existing natural coastal habitat in the Metro Bay Region COMMITMENT & INTEGRITY DRIVE RESULTS
4 COMMITMENT & INTEGRITY DRIVE RESULTS
5 Urban Coastal Greenway Policy Requirements for Metro Bay Region Projects 15% Minimum Vegetation Coverage Implementation of LID Techniques for Stormwater Management Public Access to the Shoreline Designated Urban Coastal Greenway with Native and Sustainable Vegetation COMMITMENT & INTEGRITY DRIVE RESULTS
6 Project Site Background Site is a university located within the Urban Coastal Greenway of the Metro Bay Region ~110-acre university campus situated on a former industrial property Woodard & Curran was contracted by the university to evaluate LID techniques under UCG Policy for 13-acres of proposed surface parking facilities at the campus. COMMITMENT & INTEGRITY DRIVE RESULTS
7 Site Characteristics Urban fill soils of variable infiltration capabilities High groundwater table Topographically flat Public water supply COMMITMENT & INTEGRITY DRIVE RESULTS
8 Evaluation of Low Impact Development (LID) Techniques Porous Asphalt Pavement Bio-retention Ponds Underground Infiltration COMMITMENT & INTEGRITY DRIVE RESULTS
9 LID Evaluation Criteria Suitability for the Site Performance of the LID technique Cost Maintenance COMMITMENT & INTEGRITY DRIVE RESULTS
10 Porous Asphalt Pavement COMMITMENT & INTEGRITY DRIVE RESULTS
11 Porous Pavement - How it Works 1 porous leveling course 1 porous top course 2 porous binder Crushed Stone Reservoir (~6 ) Gravel Sub-Base for permeability >2.5 ft/day COMMITMENT & INTEGRITY DRIVE RESULTS
12 Optimal Porous Pavement Site Requirements Site usage low volume/low speed Underlying soils field-verified permeability between inches per hour Depth to bedrock >4 feet from base of system On-site slopes <5% Depth to seasonal high water table >3 feet from base of system Situated >100 feet from public water supply wells, > 10 feet from building foundations Protection from wind-blown sediments COMMITMENT & INTEGRITY DRIVE RESULTS
13 Porous Pavement Maintenance Requirements Vacuum sweeping and/or pressure washing Use environmentally benign deicers in lieu of salt Monthly inspection of pavement surface for deterioration Inspection after storm events to ensure functionality COMMITMENT & INTEGRITY DRIVE RESULTS
14 Porous Pavement Advantages Reduced amount of cuts and fills on existing flat sites Reduced amount of stormwater infrastructure such as piping, catch basins, retention ponds, curbing, etc. Decreased need for plowing and salting Increased groundwater recharge Increased skid resistance/traction COMMITMENT & INTEGRITY DRIVE RESULTS
15 Porous Pavement Disadvantages Lower load-bearing capacity than conventional asphalts Limitations to de-icing procedures Premium costs associated with maintenance requirements Potential for pavement surface clogging Accidental seal coating or similar surface treatment will cause failure COMMITMENT & INTEGRITY DRIVE RESULTS
16 Bio-Retention Ponds COMMITMENT & INTEGRITY DRIVE RESULTS
17 How it Works COMMITMENT & INTEGRITY DRIVE RESULTS
18 Optimal Bio-Retention Pond Site Requirements Use for small sub-drainage areas. RI agencies recommend <5 acres; others <2 acres Depth to seasonal high water table should be > 2 feet from the pond invert (>4 feet in ponds without underdrains) On-site slopes should be <20% COMMITMENT & INTEGRITY DRIVE RESULTS
19 Bio-Retention Pond Maintenance Requirements Routine periodic maintenance of landscaped areas i.e. weeding, pruning, and mulch replacement Annual inspections to observe health of trees and shrubs and system functionality Surface should be rototilled or cultivated if standing water is observed >48 hours Removal of accumulated sediment and debris periodically COMMITMENT & INTEGRITY DRIVE RESULTS
20 Bio-Retention Pond Advantages Pollutant treatment for solids, metals, nutrients and hydrocarbons Increased groundwater recharge for unlined systems Reduction of urban heat effects Ease of maintenance Can be lined if infiltration is prohibited on a contaminated site COMMITMENT & INTEGRITY DRIVE RESULTS
21 Bio-Retention Pond Disadvantages Not applicable for steeply sloped sites Not conducive for receiving piped stormwater Shallow pond depth demands more land area than traditional water quality pond COMMITMENT & INTEGRITY DRIVE RESULTS
22 Underground Infiltration COMMITMENT & INTEGRITY DRIVE RESULTS
23 How it Works COMMITMENT & INTEGRITY DRIVE RESULTS
24 Optimal Underground Infiltration Site Requirements Depth to seasonal high groundwater should be >3 feet from bottom of the system Underlying soil infiltration capacity should range from inches per hour, clay content <30%, and silt/clay content <40% Storage chambers have minimum and maximum requirements (StormTech minimum cover is 18 inches and maximum cover is 8 feet) Site slopes should be <15% COMMITMENT & INTEGRITY DRIVE RESULTS
25 Site Requirements cont d Recommended Setbacks: 100 feet from on-site sewage disposal systems 400 feet from community wells 100 feet from private wells 25 feet from any property line 20 feet from any structure (50 ft from residential) 200 feet from surface water bodies 50 feet from a designated CRMC buffer zone COMMITMENT & INTEGRITY DRIVE RESULTS
26 Underground Infiltration Maintenance Requirements Bi-annual inspection of pretreatment devices and chambers Cleaning of pretreatment devices performed as necessary Removal of accumulated sediment >3 inches COMMITMENT & INTEGRITY DRIVE RESULTS
27 Underground Infiltration Advantages Increased groundwater recharge Flexibility in system location and configuration (i.e. the system can be configured and located as needed to best suit the application) COMMITMENT & INTEGRITY DRIVE RESULTS
28 Underground Infiltration Disadvantages Requires pretreatment to minimize maintenance Restricted accessibility for maintenance (sediment removal) If clogging cannot be corrected by high pressure flushing replacement of the system would be required Requires piping system infrastructure to collect and direct the stormwater into the system Some states require an Underground Injection Control permit COMMITMENT & INTEGRITY DRIVE RESULTS
29 Cost Comparison COMMITMENT & INTEGRITY DRIVE RESULTS
30 Costing Methodology Consistent costs that would be required for all LID techniques were not considered (i.e. grading, pavement striping) Capital cost estimates for varying components of LID techniques were considered COMMITMENT & INTEGRITY DRIVE RESULTS
31 Capital Cost Variations Among LID Techniques (March 2008) Least Expensive Porous Pavement Bio-Retention Ponds + 7% Underground Infiltration +15% Maintenance costs expected to be greatest for porous pavement systems COMMITMENT & INTEGRITY DRIVE RESULTS
32 Evaluation COMMITMENT & INTEGRITY DRIVE RESULTS
33 Evaluation of LID Techniques Site Suitability Porous pavement and Bio-Retention most suitable for variable groundwater elevation Performance Bio-Retention most reliable design Cost Porous pavement least capital cost Maintenance Bio-Retention easiest maintenance COMMITMENT & INTEGRITY DRIVE RESULTS
34 Conclusions COMMITMENT & INTEGRITY DRIVE RESULTS
35 All three LID techniques were viable choices for the parking lot Initial costing for each LID technique was comparable Bio-Retention Ponds were ultimately chosen by the client because of their ability to accommodate the variable groundwater table and relatively low maintenance costs COMMITMENT & INTEGRITY DRIVE RESULTS
