Why floods behave differently here

Larkspur is a small incorporated town on the high ground of the Palmer Divide, with Plum Creek drainages running north toward Castle Rock. Perry Park, to the west, is an unincorporated area of homes scattered among red sandstone formations and ponderosa pine, closer to the foothills where storms can build quickly over steep ground.

In these areas, water arrives from canyons and drainages rather than from engineered subdivision swales. A thunderstorm over the foothills can send runoff down a drainage that was dry an hour earlier, and gravel roads and driveway culverts take the brunt. Homes are often on larger lots with private wells and septic systems, which adds well disinfection and drain field concerns to any cleanup.

Distance matters too. Cleanup contractors coming from the Denver or Colorado Springs areas face longer drives, and after a widespread storm, washed-out roads can delay access further. Households here benefit from having basic extraction and protective gear on hand.

Common questions

Is Perry Park part of the Town of Larkspur?
Generally no; Perry Park is commonly described as unincorporated Douglas County. Boundaries can be confusing, so confirm your jurisdiction with the County before applying for any permit.
How long might it take for flood cleanup help to reach a home here?
It depends on where the contractor is based, road conditions and how many other calls they have after the same storm. Ask for a realistic time when you call, and start safe extraction yourself in the meantime.
