Some ways you can prevent stormwater pollution
- Dispose of household chemicals properly. Utilize Douglas County's low-cost household service for hazardous waste removal, available year-round.
- Spring Up the Creek event. Join volunteers in picking up trash along East Plum Creek at the Spring Up the Creek event held every May.
- Prescription drug drop off. Drop off unused or expired prescription drugs in the lobby of the Castle Rock Police Department, 100 Perry Street, during regular business hours.
- Pick up pet waste. Dog waste can contaminate stormwater run-off, ending up in our water supply. Dog waste is not a fertilizer and contains harmful amounts of nitrogen, which may spread noxious weeds. In addition, it can spread worms and other parasites, as well as many different illnesses and diseases, including E coli. Per Town Municipal Code, dog owners are required by law to clean-up their dogs' waste, and can be fined for failing to do so.
- To report violators on public property, please contact the Police Department at 303-663-6100 or report a concern online.
- To report violators on private property, please contact the Douglas County Health Department at 303-660-7401.
- Sponsor a dog waste station along the Town's trails. Discover more details on dog waste stations..
- Use fertilizers sparingly. If over-applied, rain carries away the excess nutrients the plants do not need and washes them to the nearest waterway, causing excess algae growth that uses up vital oxygen for fish.
- Don't wash lawn and yard clippings into the street and drains. The excess phosphorous and nitrogen are too much for the natural stream to handle and are harmful to wildlife.
- Keep streets clear of landscaping materials. Do not (even temporarily) store landscape materials in the street or sidewalk; rock, mulch and soil should be delivered and placed on your driveway.
- Clean up automotive and chemical spills. Keep vehicles in good condition to minimize drips and clean up chemical spills using dry clean up methods. One drop of oil can pollute one million drops of water.
- Dispose of fats, oils and grease in the trash can. Landfills are equipped to handle these materials. Freeze them for easier disposal.
- Make sure trash is in the trash can. Keep trash can lids closed, secure loads in open vehicles, and pick up litter in the streets to minimize litter scattered by wind or rain. Sweep and dispose of waste in a trash can instead of using a water hose to clean driveways and sidewalks.
- Properly dispose of paint. Unused or leftover latex paint can be dropped off at some area paint retailers for reuse. Dried out water-based latex paint can be safely and legally disposed of in regular household garbage. Mixing the paint with kitty litter, concrete-mix, or soil will help speed the drying process. Empty or dried-out cans of paint can be discarded in the trash if the lids are removed.
- Learn more about your watersheds. Castle Rock Water participates in regional programs and partnerships to improve stormwater quality throughout our surrounding watershed. The Cooperative for Local Environmental Awareness and Responsibility (CLEAR) provides education regarding our watershed and stormwater quality. Remember, One Thing is CLEAR, our creeks, rivers and lakes depend on you.
If you see illegal or accidental dumping, please contact our Stormwater Hotline at 720-733-2235 as soon as possible.
Watershed Protection Map
Castle Rock lies within two watersheds: Chatfield and Cherry Creek. The Castle Rock Watershed Protection District map (PDF) was updated in 2021 and adds components of the Cherry Creek Watershed to the protection district consistent with the new water facilities Castle Rock Water has added in this watershed. Per municipal code section 4.02.020 -Jurisdiction Map, this map has been administratively updated in accordance with code and is available with the Town Clerk and on the website for inspection.
