The commission approved the stakeholder-developed implementation plan on January 30, 2013. This I-Plan was developed by stakeholders in the Bacteria Implementation Group (BIG).

The I-Plan identifies eleven primary strategies for achieving environmental goals. These strategies relate to:

  • wastewater treatment facilities
  • on-site sewage facilities
  • sanitary sewer systems
  • stormwater and land development
  • construction
  • illicit discharges and dumping
  • agriculture and animals
  • residential areas
  • monitoring progress and updating the plan
  • research
  • a geographic priority framework

The I-Plan outlines numerous activities under each of these strategies. Read the I-Plan.

Grant Funded Projects to Support the I-Plan

The TCEQ's Nonpoint Source Program is supporting these projects that help reduce bacteria in the project-area waterways.

  • Clear Creek Tidal, installing low impact development (LID) features in League City.
  • Halls-Bayou–Westfield Estates, implemented low-flow water devices, a pet-waste program, and outreach for managing on-site wastewater facilities in Westfield Estates.
  • Lake Houston Wetland Demonstration, installed water quality exhibits at the WaterWorks Science and Education Center.
  • Whiteoak Bayou, installing low impact development (LID) features in a two-block area of the Cottage Grove subdivision, which is being redeveloped from single family residences to town houses.
  • Coastal Areas: On-Site Sewage Facilities Phase 1 and Phase 2:  locating, pumping out, and replacing malfunctioning OSSFs within the Coastal Zone Management Zone as well as providing training programs for homeowners and local health department staff.
  • Roadway LID Demonstration: installing and monitoring the performance of LID features for roadways in Harris County.
  • Houston Area Trash Bash: removing trash from waterways at about 17 sites in the Houston-Galveston area.

Lake Houston Watersheds

Stakeholders undertook various activities to improve conditions in the lake prior to development of the I-Plan.

  • Converting from Septic Systems to Wastewater Collection Systems (July 2008)
    $500,000 grant to reduce anthropogenic sources of bacteria in the watershed.
  • IDDE Outfall Database - Database tool available for IDDE (Illicit Discharge Detection and Elimination).
  • Storm Water Workshop Adobe Acrobat PDF Document Conroe, Texas (April 2008)
    • A one-day event focused on storm water issues for communities in TMDL watersheds, with or without a MS4 storm water permit.
  • Nature Fest at Jesse Jones Park Adobe Acrobat PDF Document Precinct 4 Houston (March 2008)
    • Over 1,200 members of the community attended Nature Fest. Watershed models and water quality literature were used to educate the public on the importance of preventing bacteria from entering Spring Creek.
