§ 16.2.1. Grasses

New or improved earthen channels, earthen retention facilities, and earthen detention facilities will be vegetated by seeding or sodding.

Facilities that are within private easements shall also meet the same seeding and sodding requirements.

New earthen facilities and alterations to existing facilities shall be planted with drought resistant, low growth, native species grasses which will allow unobstructed passage of floodwaters. Recommended grasses and groundcover can be found in Appendix E "San Antonio Recommended Plant List - All Suited to Xeriscape Planting Methods" found in the current City of San Antonio Unified Development Code. Johnson grass, giant ragweed and other invasive species shall not be allowed to promulgate in earthen facilities.
