Clean Coast Texas: Stormwater & League City's Development Code
·OnlineOnlineClean Coast Texas Lunch & Learn Webinar:
How League City Writes Stormwater into its Development Code
Thursday, June 4, 11:00 AM - 12:00 PM CTLink to register:
Meeting Registration - ZoomWhat happens when a fast-growing Texas coastal city decides a detention pond should do more than hold water? This session will trace League City's three-part journey in smarter stormwater management: from a 3.75-acre green infrastructure teaching park built with Clean Water Act 319(h) funding, to a post-Hurricane Harvey ordinance overhaul that raised the City's flood protection standards well beyond NFIP minimums, to a newly adopted development code that ties parkland dedication credits to the ecological quality of detention facilities. Along the way, the story includes a 100-year-old live oak tree moved by four cranes in the middle of the night and what that moment says about a community's values. League City's experience offers a practical look at what works, what Harvey forced us to rethink, and how League City is trying to get ahead of development rather than clean up after it.
Speaker: Christopher Sims, PE, is the Executive Director of Development Services for the City of League City, Texas, the largest municipality in Galveston County
