Layer: River Corridor (ID: 7)

Name: River Corridor

Display Field: Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This Corridor follows the description written in the City of San Marcos Land Development Code. South of the confluence of the San Marcos and Blanco rivers, the Corridor tracks, generally, East, along the floodplain of the San Marcos River while trying to exclude the floodplain of the Blanco River to a point 4000 feet East of the confluence. The Corridor turns Northeast for a distance of 2000 feet, before turning East once more following the floodplain defined by the 1982 FEMA FIRM Map Panel 4800940155B Insert, up to US Hwy 80, then along US 80 to the San Marcos ETJ. The Corridor follows the ETJ South until the floodplain, as defined by the 1978 FEMA FIRM Map Panel 4803210010A, where the Corridor turns west, following the floodplain for a distance of approximately 2800 feet, where the Corridor then turns South, determined by a 200 feet buffer from the riverbank, which exceeds the limits of the floodplain. The Corridor continues to follow this 200 feet buffer from the river bank (initially Southwest, then West; a distance of approximately 3400 feet) until the floodpain, as defined by 1978 FEMA FIRM Map Panel 4803210010A, exceeds the 200 feet buffer. The Corridor follows the floodplain until it meets an area of highly erodible soil, as defined by NRCS Soil Map for Hays County, where the buffer increase to 1000 feet from the centerline of the San Marcos River. The Corridor tracks generally west, for approximately 9900 feet, where the Corridor is then generally bounded by the floodplain, as defined by the 1978 FEMA FIRM Map Panel 4803210010A, tracking Northwest. At a few points, where the river bends farther Southwest, the Corridor is bound by an offset of 200 feet from the river bank, instead of the floodplain. The Corridor turns Southwest, along the floodplain, as defined by the 1978 FEMA FIRM Map Panel 4803210010A, then follows Luciano Flores Blvd, Northwest to IH-35. The Corridor then follows as stated in the City of San Marcos Land Development Code.
