The natural draw adjacent to buildings 3 and 7 is designed as a sunken garden that filters runoff with a trickle channel and pollinator plantings. 2. The site will meet full landscape requirements as specified by code despite the site being located in the ETJ, where landscape ordinance do not apply. Notably, all parking spaces will be within 50 LF radius of a shade tree 3. All new 3:1 slopes will use the 609S upland seed mix with additional shrubs and trees provided near the base of the slopes to assist with stabilization. . APPLICANT PRESENTATION
