V. Brief Review of April 26, 2023 meeting:
• Roadway Master Plan comments (due May 11th, 2023)
• SharePoint access issues
• Concerns, suggestions, remarks.
VI. Discussion or Possible Action:
• Stormwater Master Plan Review: Presentation by Pape-Dawson:
Hydrology & Hydraulics • Update studies citywide • Method varies based on infrastructure and drainage patterns • Existing and ultimate conditions
Capital Improvement Plan Update • Identify Potential Mitigation Areas (PMAs) • Rank PMAs based on structure and roadway flooding • Identify critical PMAs • Develop future capital project
Impact Fee Implementation • Service Areas • Identify Funding Source • Develop Fees based on Service Area and Growth Potential Project Types:
Channel Improvements • Add capacity to existing channels • Mitigate adjacent flooding • Improve efficiency of underground pipe systems • Add new channels to increase overall system capacity
Storm Drain (Pipe) System Improvements • Upsize/Add trunk lines for major conveyance • New storm drains for intermediate sized systems • Increased capacity for street and neighborhood drainage
Regional Detention Ponds • Typically drain within 24-48 hours • Mitigate current impacts to existing neighborhoods • Planned mitigation for future development • Can be modified for water quality benefits • Coordinate locations with flight paths
Low Water Crossings/Bridge Replacements • Improve access to currently developed areas • Provide access for areas to be developed • Emergency connectivity Develop Capital Projects:
Determine Proposed Improvements • Channel, Pipe Systems, Detention, etc.
Estimate Costs • Drainage Components • ROW Acquisition • Major Utility Coordination
Prepare CIP Summary • Scope, Cost, Location, & Layout Potential Mitigation Areas:
Developed Areas • Apparently inundated structures → 100-year storm, structures at risk at 6” flood depth → 100-year storm, structures at risk at 12” flood depth → 10-year storm, structures at risk at 6” flood depth → 10-year storm, structures at risk at 12” flood depth → Roadways → No specific metric, manual assessment of flooded roadways → Is conveyance controlled by storm surge?
Undeveloped/Partially Developed Areas
• Potentially flooded structures
→ 10-year storm, structures at risk at 12” flood depth
• Roadways
→ No specific metric, manual assessment of flooded roadways • Impacts of Ultimate Development • Coordination with Tri-County Study Assumptions-Developed Areas:
Nueces River, CC Bay, Oso Bay Basins, Flour Bluff 1D/2D Modeling • 1D/2D Modeling → Analyzing capacity of the infrastructure (storm drains and channels) → Analyzing surface water movement when infrastructure overflows • City-wide analysis → Not an inlet-level model → Modeled all pipes ≥36” diameter → Excluded any pipes <36” diameter Oso Creek Basin • 1D/2D Modeling → Analyzing capacity of the infrastructure (storm drains and channels) → Analyzing surface water movement when infrastructure overflows • Future Development → Assumed ultimate development → Assumed detention throughout watershed → Major Thoroughfare Channels Funding Sources:
Federal/State Grants and Loans • American Rescue Plan Act (ARPA) • Community Development Block Grants (CDBG) → MIT, DR • Federal Emergency Management Agency (FEMA) → Hazard Mitigation Grant Program (HMGP) • Texas Water Development Board → Flood Infrastructure Fund (FIF) → Grants and Forgivable Loans → Oso Creek Bottom Rectification • Texas Department of Transportation (TxDOT) → Yorktown & Ocean Drive Bridges
Bond Programs • Large projects • Developed areas and/or growth areas
Storm Water Utility Fee • Small- to mid-size projects • Maintenance and operations • Developed areas
Impact Fees (If Adopted) • Must be attributed to growth/new development • Compare capital project costs to estimated growth within service area • Impact fees must be used within the service area, based on watershed • Service areas may be merged as the study progresses Recommendations-Developed Areas:
Nueces River, CC Bay, Oso Bay Basins, Flour Bluff 1D/2D Modeling • 35+ Projects Identified • Funding Sources → Storm Water Utility Fee → Bond Projects → Federal/State Assistance
Oso Creek Basin • Development Requirements → Mandatory Detention within Oso Creek Basin → Must outfall to a receiving channel/stream • Create Major Channel Thoroughfare System → ICL & ETJ • Funding Sources → Bond Projects → Federal/State Assistance Storm Water Impact Fees
A breakout session was held.
VII. Director’s Report: None.
VIII. Future Agenda Items: None.
IX. Adjournment: There being no further business to discuss, the meeting adjourned at 3:06 pm.
