Highland Lakes Watershed Ordinance
Dredge and fill activities on the Highland Lakes fall under the Highland Lakes Dredge and Fill Ordinance. Visit lcra.org/hldo for more information.
The Highland Lakes Watershed Ordinance helps protect water quality from stormwater runoff from development throughout the Highland Lakes region. Stormwater runoff from development can contain pollutants such as sediment, oil and grease, pesticides, herbicides, and nutrients. Through the ordinance, LCRA regulates development to manage stormwater runoff around the Highland Lakes.
- Approved water quality management facilities (vegetated filter strips and/or water quality basins) to collect stormwater runoff.
- Buffer zones that remain free of development. Read the Property Owner’s Guide to Buffer Zones.
- Temporary erosion and sediment controls.
- Permanent systems to minimize sediment migration from the site.
LCRA encourages the use of native and/or adapted plants and limiting the use of chemicals such as pesticides, herbicides and fertilizers on landscapes.
Quarries and mines covered under the HLWO must implement measures similar to other development. Read the fact sheet.
Small development projects and small quarry/mine activities located outside a creek buffer zone may be authorized without a permit by submitting a written notification and erosion/sediment control plan.
Submit questions, comments or complaints through Contact LCRA. Read more information on the complaint process for this program. View 2021 complaint statistics.
