HISTORICAL MISSION (SOUTHERN) REACH COST ESTIMATE AND FUNDING SOURCES The San Antonio River Improvements Project is scheduled for completion in phases by 2010 and funded by four sources. A budget has been allocated to the project and a Cost Analysis has been prepared to project the costs for each reach. The Cost Analysis information and corresponding Gant Chart are included as an Appendix. This budget includes funding to realign portions of the existing Mission Trails that must be alterned to follow the new river alignment. However, the cost of new Mission Trails will be funded by that project and are not included here. The implementation strategy is to: 1. Build the entire project over the next 10 years. 2. Construct a north reach and south reach concurrently during each phase. 3. Begin at the downtown area and work outward, in both southward and northward directions, as possible. The areas of highest concern in the Historical Mission Reach, such as Espada Dam, will be addressed as quickly as possible, coordinated with the availability of project funds, and may require “hop-scotching” in that reach. LONG TERM OPPORTUNITIES The SWA design team looked beyond the river right-of-way for opportunities to provide additional flood control, detention, and economic development. Several sites presented themselves and are opportunities for the future when the conditions are favorable for such improvements. These improvements are beyond the scope of the project budget and will require funding from other sources. The opportunity sites follow: 62 SAN ANTONIO RIVER DESIGN GUIDELINES Riverside Golf Course Riverside Golf Course currently has very valuable pecan tree coverage. However, in the future, these trees will decline and die, and the golf course will also require upgrading and improvements. At that time of major renovation, consideration should be given to over-excavating the golf course to provide floodwater detention during major storm events. EXISTING HIGH VALUE TREES REGRADE GOLF COURSE TO NEW DESIGN CRITERIA EXISTING GRADE TO REMAIN EXCAVATE EXISTING GRADE TO +8’ PERSPECTIVE - EXCAVATION TO CREATE GREATER STORM WATER CAPACITY NOT TO SCALE NOT TO SCALE
Concepcion Park A large parcel of land owned by the Archdiocese of San Antonio exists east of the river at Concepcion Park. A long-term opportunity exists for this land to be excavated for flood detention, and planted as park space. Consideration should be given to overexcavating the basin to a depth of 18 to 20 feet so that it would hold water at all times. This effort would not only help mitigate potential flooding but also increase the value of the surrounding property. NOT TO SCALE Padre Park Padre Park offers the opportunity for major stormwater detention, similar to the proposal for Riverside Golf Course. This should be considered in the future when upgrades are made. NOT TO SCALE SAN ANTONIO RIVER DESIGN GUIDELINES 63
