THE RIGHT PROCESS 1. Understand the basin’s history and built environment and relevance to local flooding issues 2. Listen and understand community values 3. Enable community conversations around alternatives 4. Identify a toolbox of solutions/strategies 5. Foster community support, ownership and participation

HALE PARKWAY | CONVEYANCE NEEDS • Design Goal: 100-year event • Potential Conveyance 1. Existing 78” pipe (428 cfs) 2. Proposed 120” pipe, or rough equivalent (1000 cfs) - available underground capacity of future downstream system (Jackson Street Storm) 3. Greenway to handle remaining cfs needed (appx. 877 cfs) • Future goal of serving the Severn/Jersey Sump with the underground pipe (up to 1000 cfs)
HALE PARKWAY | TRANSPORTATION 20’ 32-40’ 80-90’ Linear Stormwater Park Pedestrian Roadway Zone 150’ R.O.W Traffic Parking
