Document Damage Take color photographs or video of any damages resulting from the flood. Before Entering a Flooded Building. Boil Water Until local authorities proclaim your water supply to be safe, boil water for drinking and food preparation. Water should be boiled vigorously for five minutes before using. Careful Cleaning. Flood waters pick up sewage and chemicals from roads, farms, and factories.
If your home has been flooded, protect your family's health by cleaning up your house right away. Throw out foods and medicines that may have come into contact with flood water. Be careful walking around. After a flood, steps and floors are often slippery with mud and covered with debris, including nails and broken glass.
Floodplain Development. In addition to federal standards, Harris County has Floodplain Management Regulations more stringent than the federal standards in place which govern development within the SFHA. These standards apply to new structures and to substantial improvements of existing structures. Harris County defines a substantial improvement as any reconstruction, rehabilitation, or addition to an existing structure, the cost of which exceeds 50 percent of the structure's appraised or market value.
Key components of Floodplain Development: - A Floodplain Development Permit is required for all work in the floodplain. Floodplain Development Permit.
Any activity performed in the floodplain must have a Floodplain Development Permit. This includes grading, filling, residential construction and commercial construction. To obtain a permit you must complete a residential Permit Application and comply with Floodplain Management Regulations. Complete and return the form along with 3 sets of plans of the project to the Harris County Permit Office. The plans must clearly show existing and proposed contours at the site with all elevations submitted on NAVD datum.
This must confirm that the finished floor of the actual construction is at least inches above the BFE. Copies of previously submitted elevation certificates are available at the Harris County Permit Office. If your property lies within the SFHA, a Residential Permit Application and compliance with Floodplain Management Regulations is required for any work, including: - Grading - Filling - Paving - Construction of new structures including additions to the home - Miscellaneous pools, gazebos, retaining walls, fences, etc.
You may be required to bring your home or business into compliance with current Floodplain Management Regulations development standards if: - Your home or business has been significantly damaged due to flooding, resulting in the need for substantial improvements, OR - You are proposing substantial improvements to your home or business such as an addition or renovation.
County staff is available to make site visits, if requested, to review flooding and drainage issues. Contact the Harris County Permit Office at for further information and prior to undertaking any activity within the floodplain. Drainage System Maintenance. What is Storm Water? The term storm water refers to rainwater.
Storm water washes down storm drains on the curbs of roads and leads directly into lakes, rivers, and streams. Unlike wastewater, it is untreated and can carry pollutants, sediments, and trash directly into our natural water resources. As storm water runoff travels over the land, it picks up all kinds of chemicals, waste, and trash that are not naturally found in our waterways.
Storm water runoff enters the storm drain system through inlets, and discharges untreated into creeks, bayous, channels, lakes, and rivers. Some chemicals and other substances in storm water can be toxic, even at small levels, endangering plants and animals that depend on the water to survive. Pollution of our waterways can also mean we cannot boat, swim, or fish because it is unpleasant or even unsafe.
Storm water runoff from properties throughout Harris County flows to one of 1, channels totaling about 2, miles in length within twenty-two watersheds of Harris County, joining Galveston Bay and flowing downstream to the Gulf of Mexico. Storm water pollution can be controlled if everyone plays a part in preventing these substances from entering the storm drain inlets in the streets where they live and work. You can help prevent storm water pollution by eliminating illicit discharges, exercising responsible use of herbicides, pesticides, and fertilizers in lawn and landscape maintenance, and proper disposal of used oil and toxic materials.
What Can We Do? Please do your part to keep inlets and drainage ways clear of brush and debris. Maintain your vehicle so hoses and reservoirs do not leak or break causing fluids to spill onto streets. Don't pour used motor oil, antifreeze, old pesticides or any other pollutants into the storm drainage system.
Use a mulching mower or bag your grass and leaves instead of blowing the yard waste into the street. Yard waste can clog storm drains. Pick up litter around your neighborhood or business so that trash doesn't collect on drainage inlets or clog storm sewer pipes. If you spot a blocked drain or notice illegal dumping, call the Harris County Precinct Office in your area, and someone will investigate. Putting foreign substances into the storm sewer is a violation of Harris County Storm Water Quality Regulations and may result in a fine.
Our Drainage System. Harris County and Harris County Flood Control District maintain our county-wide system of drainage improvements, including 1, channels totaling about 2, miles in length within twenty-two watersheds. When the drainage system is overwhelmed, "localized flooding" can be the result. Harris County Flood Control District has a drainage maintenance program in which crews clean out debris that has collected within channels.
Flood Map Modernization. The Map Modernization project provides property owners throughout Harris County with up-to-date, reliable, Internet accessible information about their flood risk on a property by property basis. It is important to note that the calculated flood levels based on extensive hydraulic modeling in Harris County are not changing with the issuance of the maps. Rather, more accurate survey information is allowing FEMA to show the limits of the floodplain more accurately than ever before.
In other words, properties which are now shown on the map to be within the floodplain were actually always within the floodplain. No physical features have changed which adversely impacted the properties and caused the shift in floodplain limits. On this mapping tool, the shade of red indicates the depth of the water. Dark red indicates deep ponding and light red indicates shallow ponding. Channels - Waterways through which stormwater moves or is directed.
It is a generic term used by the Harris County Flood Control District in reference to bayous, creeks, small tributaries and some ditches. When identifying channels, the Flood Control District uses a combination of letters and numbers to help easily identify the location of a waterway.
On this mapping tool, channels have been labeled with formal identification numbers used by the Flood Control District. Open Channels — Channels that are open and visible.
