Section 3.2.10 - Stormwater Wetland 3.2.10 Stormwater Wetland Primary Water Quality Facility Description: Constructed wetland used for stormwater management. Runoff is both stored and treated in the wetland facility. KEY CONSIDERATIONS DESIGN CRITERIA: • Minimum contributing drainage area of 25 acres • Minimum dry weather flow path of 2:1 (length: width) should be provided from inflow to outflow • Minimum of 35% of total surface area should have a depth of 6 inches or less; 10% to 20% of surface area should be deep pool (1.5 to 6 foot depth) ADVANTAGES / BENEFITS: • Good nutrient removal • Provides natural wildlife habitat • Relatively low maintenance costs DISADVANTAGES / LIMITATIONS: • Requires large land area • Needs continuous baseflow for viable wetland • Sediment regulation is critical to sustain wetlands • Large commitment to establish vegetation in the first 3 years MAINTENANCE REQUIREMENTS: • Replace wetland vegetation to maintain at least 50% surface area coverage • Remove invasive vegetation • Monitor sediment accumulation and remove periodically H M POLLUTANT REMOVAL Total Suspended Solids Nutrients – Total Phosphorus & Total Nitrogen STORMWATER MANAGEMENT SUITABILITY Water Quality Protection Channel Protection On-Site Flood Control Downstream Flood Control IMPLEMENTATION CONSIDERATIONS H M Land Requirements Capital Costs Maintenance Burden M M M Shallow Wetland ED Shallow Wetland Pond/Wetland Residential Subdivision Use: Yes High Density/Ultra-Urban: No Drainage Area: 25 acres min Soils: Hydrologic group ‘A’ and ‘B’ soils may require liner M H Metals – Cadmium, Copper, Lead & Zinc Pathogens – Coliform, Streptococci & E.
