A different setting from the planned grid

Roxborough Park feels very different from the rolling, planned streets of Highlands Ranch. Homes sit on hillsides and among rock outcrops, many with walkout levels, decks and long driveways. Construction spans several decades, from the 1970s into the 2000s, so plumbing and materials vary widely from one house to the next.

Slopes and rock change how water moves. Heavy summer storms send runoff across lots quickly, and snowmelt can follow rock faces toward foundations. Exposed sites at higher elevation also see colder nights and stronger wind than the plains below.

Roxborough Park situations

  • IfWater enters a walkout level during a stormThenLook at the uphill side and any rock face or swale feeding toward the house.
  • IfPipes run through an unheated crawl space or garageThenInsulate and consider heat tape before winter; these freeze first on exposed sites.
  • IfLeak happens during a snowstormThenPlan for slower access; shut off water and protect belongings while waiting.
  • IfDecks above lower-level doors dripThenCheck flashing and door thresholds where deck water lands.

Preparing a hillside home

  • Know the main shutoff and keep a valve key or wrench next to it
  • Keep a wet/dry vacuum and towels for the first hours after a leak
  • Clear drainage paths and culverts before summer storm season
  • Add a low-temperature alert to the thermostat if it supports one
  • Write down how a contractor would find the house on unfamiliar roads

Common questions

Do homes in Roxborough Park have wells or septic systems?
Most homes are served by a water and sanitation district, but service can vary around the edges of the area. Check your bills or ask the district. Homes on wells or septic have extra equipment, such as pressure tanks, that can leak.
Are freeze risks greater here than in Highlands Ranch?
Exposed hillside homes and those with plumbing in crawl spaces, garages or cantilevered rooms can face more cold and wind. Insulating vulnerable runs and keeping heat steady matter.
Can wildlife cause water damage?
Rodents and other animals can tear insulation in crawl spaces and garages, leaving pipes exposed to cold. Check for damage before winter.
Who regulates regrading on these slopes?
Douglas County handles building permits for the unincorporated area. Grading and drainage changes on steep lots may need additional review, so ask the county before moving much soil.
