However, an additional 13 miles of urban riverexist beyond downtown: upstream to the headwaters atthe University of the Incarnate Word and downstreamto the Espada Mission. The possibilities for theseriver reaches have not yet been charted.Bexar County, the City of San Antonio, and the SanAntonio River Authority formed the San AntonioRiver Oversight Committee (SAROC), comprised of adiverse group of citizens, in 1998. These four entitieshave joined for a major undertaking, the preservationand restoration of the San Antonio River. Under theirleadership, the north and south reaches will be masterplanned for future enhancement of San Antoniocitizen?s and visitor?s lives.PROJECT AREAThe San Antonio River Improvements Projectincludes two reaches. The Museum (Northern) Reachbegins at Lexington Street and runs north about fourmiles to E. Hildebrand Avenue at Brackenridge Park.Due to two distinct areas within this reach, it has beenfurther subdivided in the Museum (Northern)?Urban? Reach from Lexington to Josephine and theMuseum (Northern) ?Park? Reach from Josephine toHildebrand.The Historical Mission (Southern) Reach extendssouthward from S. Alamo Street to the EspadaMission just below Interstate Loop 410. This reachmeasures approximately nine miles, for an entireproject length of about 13 linear miles.MASTER PLANNING PROCESSSWA Group was retained in April 2000 to provideMaster Planning services for the San Antonio RiverImprovements Project. Their charge was:? to create a vision for the project area that wouldenhance the river and the citizen?s lives? confirm that the hydraulic capabilities are notcompromised? evaluate future land uses? test the cost analysis to confirm the project?saffordability? prepare a Desig
