  2. Project Limits

  3. Project Partners • City of San Antonio – Provides project funding for project amenities (i.e.. Sidewalks, Landscaping, Lighting, etc.) and recreation. San Antonio Water System is providing funding for utility relocation • Bexar County – Provides project funding for flood control and river restoration elements of the project • San Antonio River Authority(SARA) – Provides project administration and management • U.S. Army Corps of Engineers (USACE) – Provides federal funding for river restoration and some recreational funding • San Antonio River Foundation – Provides private funding to support project • San Antonio River Oversight Committee – A 22 person citizens committee established in 1998 with members appointed by the City, County and SARA representing the various neighborhood and business stakeholders along the river.

  4. Project Benefits • Ecosystem Restoration – The changes proposed will increase water quality and the quantity and diversity of plant and animal species. • Flood Reduction – Project will maintain or decrease the elevation of the 100 year floodplain. • Quality of Life – Add to San Antonio’s unique charm and make the city more attractive to residents, visitors, and businesses and provide enhanced recreational opportunities along an expanded linear park system. • Cultural connections – Linking people, neighborhoods and cultural resources and celebrating the historical connection of the river to four of the five historic missions in the San Antonio Missions National Historical Park. • Economic Development – Promote business development along and adjacent to the river. Improvements will also enhance tourism.

  5. Preliminary Design Completed 2004 Concept Design Completed 2001 Final Design Under Way Construction Phase Beginning in 4th Quarter 2006 Project Development Process

  6. Project Schedule

  7. Current Project Estimate October 2005Presented in Million Dollars (inflated) * Based on GRR preliminary estimates reflecting USACE District initial planning and feasibility. The project budget includes a higher estimated cost for inflation over the life of the project than reflected in the GRR. USACE will further refine construction cost estimates during final design phase.

  8. Eagleland

  9. Eagleland Project Before Completion of Phase I

  10. Eagleland – Cut Stone Wall

  11. Eagleland - Riffle Structure

  12. Eagleland – Outfall #10

  13. Mission Reach Proposed USACE project limits

  14. Ecosystem Restoration Existing River Channel Currently, a riverine system does not exist within the Mission Reach. The riparian habitat is non-existent and the aquatic habitat suffers sever degradation, largely due to the absence of a functioning riparian corridor. Current riverine system rates a 1.2* (based on scale with 1 as extremely degraded and 10 as pristine) *Per US Army Corps of Engineers Study

  15. Ecosystem Restoration • Proposed River Channel • Through geomorphic and sediment transport analysis a more stable and natural river channel will be produced. • Requires the acquisition of 128 acres of adjacent land • Requires the excavation of 2.7 million cubic yards of soil Proposed project riveine system rates an 8.2* (based on scale with 1 as extremely degraded and 10 as pristine) *After 50 year maturity period per US Army Corps of Engineers Study

  16. Project Vision • Historical Mission Reach at Ashley Road (looking North) Proposed Existing
