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

COMMUNITY VOICES

  • Slower speeds, calmer traffic, more pedestrian crossings Hale

Parkway to access Lindsley Park and 9CO development amenities

  • Continuous pedestrian facilities along Hale Pkwy
  • Concern over traffic congestion near Colorado Blvd
  • Maintain Lindsley Park “as is”
  • Limit / discourage neighborhood traffic “cut-throughs”
  • More green spaces for walking and jogging
  • Keep a healthy tree canopy

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)
