Were you aware that a majority of the City of Cedar Park is located either within the Recharge or Contributing Zone of the Edwards Aquifer? You may be asking yourself, “What is the Edwards Aquifer”? The Edwards Aquifer is one of the most valuable resources in the Central Texas area. This aquifer provides water for municipal, industrial and agricultural uses as well as sustaining a number or rare and endangered species. To preserve these beneficial uses, Texans must protect water quality in this aquifer and other waterways from degradation resulting from human activity.

The City of Cedar Park is looking to its residents to improve water quality as it pertains to storm drain facilities such as street inlets and detention pond facilities. The City of Cedar Park desires that no resident dumps ANY KIND of substance into a street inlet, channel or pond facility. Any substance put in a street inlet makes its way to our local Waterways, Streams, Creeks, Ponds, Lakes and Edwards Aquifer and can affect YOUR water use.

Were you aware that the City of Cedar Park also has an existing ordinance restricting dumping into local storm drain systems? The Ordinance addressing Offenses and Nuisances (article 8.06.006 (b)) states that “No person shall sweep into or deposit in any street or sidewalk the accumulation of yard refuse, clippings, or litter from any building or property”. In addition to the City’s Ordinances, the City of Cedar Park will be retrofitting existing public storm inlets and requiring new inlets be marked with a “No Dumping, Drains to Waterway” marker. The markers will be similar to the following:

Not washing your car in the driveway:
Washing your car at home introduces soap, oil, hazardous chemicals and engine grime to the environment. The dirty water and other chemicals wash off your car, flow down your driveway, down the street, into a curb inlet and end up in a nearby creek. Detergents in our creeks and ponds pose a very real threat to our fish. Use a commercial car wash instead. However, if you must wash your car at home, these tips will help minimize pollution: try using just water and a rag; use only minimal amounts of soap; use a spray release nozzle for your hose to reduce water use and runoff into the street; or wash your car on the lawn - your yard acts as a sponge and prevents soapy water from flowing down the curb.

Practice Dry Cleanup Methods:
Instead of hosing down your driveway or sidewalk, use a broom to sweep up waste. For oil spills, use a product such as cat litter to absorb the oil, then sweep up the litter and place it in your trash.

Clean up after your pets:
Pet waste left on the ground will wash into creeks and lakes the next time it rains, contributing harmful bacteria, parasites and viruses to our waterways. It's important to clean up after your pets whenever they make the waste in your backyard or while out on a walk. Flush it down the toilet or wrap it in a plastic bag to be disposed of with the normal trash.
