With flooding events occuring within in the Clear Lake area, the following form has been developed to report these events to the district’s engineer. Using this form will help direct the engineers efforts to these areas for inspection. These forms will be sent to our engineering consultant directly. You can email it back to email@example.com, fax it to 281-488-6644, drop it off by our office at 900 Bay Area Blvd., or mail it in. Thank you for your cooperation.

A Short History (excerpt taken from: https://www.hcfcd.org/interactive-mapping-tools/harris-county-flood-education-mapping-tool/)
The Flood Education Mapping Tool was initially developed as a mapping tool for the Tropical Storm Allison Recovery Project (TSARP), which was launched shortly after Tropical Storm Allison struck Harris County in June 2001. Its purpose was to serve as a tool for Harris County residents to learn the location of their properties in relation to mapped 1 percent (100-year), 0.2 percent (500-year) and coastal floodplains. The Flood Education Mapping Tool includes regularly-updated floodplain information from the Federal Emergency Management Agency’s Flood Insurance Rate Map (FIRM or floodplain map) for Harris County, interactive legend options, a simple map display and easy map navigation. While the floodplains shown on the Flood Education Mapping Tool are the floodplains delineated on the FIRM for Harris County, the Flood Education Mapping Tool is not the effective FIRM.

Topography and Drainage
The general area of the Authority ranges in elevation from 10 feet mean sea level along the extreme eastern boundary to about 35 feet mean sea level along the northwestern boundary. Substantially all existing areas or areas proposed for development within the Authority are above the projected 100-year flood plain. In the general area of the Authority, there are three well-defined major watersheds. The three major drainage channels are Horsepen Bayou on the west, Armand Bayou in the central area, and Cow Bayou on the south and discharge through Clear Lake into Galveston Bay. Drainage of the developed subdivisions is accomplished by means of enclosed storm sewer systems which outfall into improved channels of the three major streams.
The Clear Lake City Water Authority has adopted a Stormwater Quality Management Plan in compliance with state regulations. The following forms are required to be submitted annually to satisfy compliance requirements.

Stormwater is rain that travels down gutters into the storm drains, flowing directly into waterways such as bayous, lakes and Galveston Bay. Impervious surfaces like driveways, sidewalks, and streets prevent storm water runoff from naturally soaking into the ground. Dumping materials into storm drains has chemicals, dirt, and other pollutants. It is never treated, so everything stormwater collects as it travels through storm drains end up in local waterways.
The sanitary sewer system collects household wastewater from toilets, showers, and sinks. The wastewater is sent to a facility where it is first treated before being released back into the environment. Stormwater is not treated since it is intended for rain runoff only and flows directly to waterways.
A storm drain system’s purpose is to prevent flooding of streets and highways by quickly and efficiently transferring rainwater into our bayous, creeks, rivers, and Galveston Bay. After the water has filled up waterways, then the streets are designed to handle the overflow, to try and prevent flood damage to property.
Very serious. The contaminated stormwater can affect vegetation, wildlife, aquatic life, and restrict swimming areas. For example:
Health: Stormwater pollution poses a serious health risk to people swimming or fishing in our local bayous, lakes, etc.
Environment: Countless marine plants and animals living in our local waterways may become sick or die from contact with stormwater pollution.
Neighborhoods: Clogged storm drains significantly decrease the quality of life in many neighborhoods throughout the city and county. These “nests” of trash and debris can attract rats and cockroaches and create foul odors affecting neighborhood aesthetics and property values. It also creates the potential for local flooding during heavy rain events.
Local ordinances and regulations prohibit anything other than uncontaminated rainwater from entering the storm drain system. Under Chapter 47-741(a) of the City of Houston Code of Ordinances, “A person commits an offense if the person threatens to introduce, introduces or causes to be introduced into the MS4 (Municipal Separate Storm Sewer System) any discharge that is not composed entirely of storm water.”
Oil can be taken to our oil recycling drop-off point located at 17507 El Camino Real. From El Camino Real, turn onto Beacon Road and drive towards the water storage tank. Please leave the used oil in a sealed container (to prevent spills) and outside the gate in the visibly marked concrete box. Please do not drop off any other chemicals, liquids, or other items that need disposal. CLCWA is only able to recycle oil at this time.
Check with your local hardware stores about recycling batteries. Businesses where you buy car batteries or tires usually recycle or properly dispose of these items.
Pet waste can be picked up by rain as it travels down the storm drain, carrying with it bacteria and other harmful materials into waterways. When walking your pet, remember to pick up the waste and dispose of it properly. Flushing pet waste is the best disposal method.
Yard waste contributes nutrients, such as nitrogen and phosphorous, which cause unwanted and uncontrolled growth of algae and aquatic weeds. Grass clippings also clog storm sewer drains, contributing to flooding.
Don’t overwater your lawn. Consider using a soaker hose instead of a sprinkler.
Use pesticides and fertilizers sparingly. Consider using organic products when possible and use chemicals in the recommended amounts.
Compost or mulch yard waste. Don’t leave yard waste in the street or sweep it into storm drains or streams. Cover piles of mulch or dirt being used for landscaping projects.

Actually dirt can clog spawning areas for fish and cover the water channel floor resulting in fish food being covered and the fish unable to sustain life.
No. Paint can be toxic to aquatic life by interfering with breathing, plant growth, and reproduction. Rinse paintbrushes out in the sink.
Use a commercial car wash that treats or recycles its wastewater, or wash your car on your yard so the water infiltrates into the ground. Use a biodegradable soap sparingly.
You can make a difference in storm water quality by simply changing a few practices at home.
Here are some easy steps:
Use less harsh, safer, cleaning alternatives. Please see this Cleaning Alternatives Guide.
Recycle or properly dispose of household products that contain chemicals such as insecticides, pesticides, batteries, paint, solvents, used motor oil and other car fluids.
Use fertilizers sparingly and sweep up driveways, sidewalks, and gutters.
Never dump anything down storm drains or in streams.
Vegetate bare spots in your yard.
Compost your yard waste.
Use the least toxic pesticides possible, follow labels, and learn how to prevent pest problems.
Direct downspouts away from paved surfaces; consider a rain garden to capture runoff.
Take your car to the carwash instead of washing it in the driveway, or wash your car on the lawn.
Check your car for leaks and recycle your motor oil.
Pick up your pet waste; flush it in the toilet or bag it.
