What Holly Hills Well Records Mean for Your Property

How deep are wells around Holly Hills?

How much water do wells make near Holly Hills?

Why the 31 ft Median Can Mislead a Holly Hills Buyer

Of the 4,180 records reporting depth, the median is 31 ft and the middle half runs from 21-57 ft. That means the central range of recorded drilling is shallow, but it is not a reliable household-well bid range when monitoring wells dominate the permit mix.

Depths also have a long upper tail: 83% are under 100 ft, the 90th percentile is 482 ft, and the deepest recorded well reaches 2,265 ft. Permits name Alluvial and Denver aquifers, while many leave the aquifer unnamed or broadly classified. The water-bearing formation and intended use matter more than proximity alone. Ask a driller to compare completed supply wells serving similar uses before choosing a target depth.

Reported Yield Near Holly Hills Is Not a Supply Guarantee

The reported median pump yield is 15.0 gpm, with the middle half between 10.0-50.0 gpm. Those figures come from only 208 records, a much narrower sample than the depth records. They describe reported pumping results, not a promise that a proposed well will sustain the same output.

Low production still deserves attention: 3% report under 1 gpm and 7% report 1-5 gpm. A low-yield well can require storage and careful management of peak household demand. Before buying, obtain the actual well's pumping-test information and ask about recovery after pumping. Neither a strong test yield nor a large pump establishes the uses or withdrawals allowed by the permit.

Shallow Water Levels Do Not Show a Falling Local Trend

Static water level is the depth to water while a well is resting, not the depth of the drilled hole. Around Holly Hills, 131 records report this measurement. The median is 15 ft below ground, and the middle half falls between 11-25 ft.

The decade medians are 13 ft in the 2010s and 12 ft in the 2020s. That series does not show a dropping water table; the later median is slightly shallower. It also does not establish that an individual well is stable, because the measurements may represent different wells and conditions. For a purchase, compare dated measurements from the same well and review its water level while pumping.

A Permit History Shaped by Monitoring Around Holly Hills

The search area contains 7,531 DWR permit records, with 3,505 recorded as constructed. Permit activity was highest in the listed decades during the 1990s and 2000s, with 1,894 and 1,898 permits respectively. The 2020s account for 418, and the newest permit year is 2025. This is not a count of operating household wells: domestic/household use represents 15% of the mix.

The most frequent driller-field entry is Authorized (Pe, Pg), at 2,945 records; do not treat that label as a contractor recommendation. Named entries include Ground Exploration Llc (Bender, Joseph T.), with 291, and Hier Drilling Co Inc (Hier, Bruce A.), with 175. Historical record frequency does not establish current availability or suitability for a residential job.

Budgeting a Holly Hills Well Beyond the Drilled Hole

The supplied drilling model assumes Denver Basin sedimentary bedrock at $50-$70 per foot. At the recorded median depth, that produces an estimated drilled-hole cost of about $1,600-$2,200. The modeled finished well, including pump, tank, trenching and electrical, is about $7,600-$14,200.

Treat that as a shallow-depth illustration, not a household-well quote. The median comes from a monitoring-heavy record set, and your permitted supply may require a different depth or construction. Request a written scope identifying casing, grout, testing and completion work, along with the pump and service connections. Site access, trench routing and the required water source should be settled before relying on a total price.

Environmental Checks Matter in This Urban Well Search

Within about 10 miles, the mapped inventory includes 628 PFAS sampling/contamination sites and 171 EPA Superfund/cleanup sites. These are reasons to investigate nearby records, not evidence that every Holly Hills well is contaminated. A sampling location is not automatically a confirmed contamination source, and distance alone does not establish a groundwater pathway.

Have the actual supply tested, with testing guided by nearby environmental records and intended use. Review casing, grout and the wellhead for potential entry points. Reported low yields also justify checking sustained pumping and recovery; a permit alone does not prove a successful supply. For building or septic work, confirm required separation, drainage and local approvals before fixing the site layout.

Before Buying or Building Near Holly Hills

Start by confirming how the parcel is legally supplied with water. An existing permit, a mapped monitoring well and an approved household supply are different things. Check the DWR permit's location, status and allowed uses, then match it to the construction report and the well actually on the property.

Use nearby records in Four Square Mile, Cherry Hills Village or Greenwood Village as leads, but compare aquifer, use and construction rather than simply choosing the closest dot. Confirm utility service options and applicable local requirements before assuming a new well or septic system is feasible. Make the purchase decision with water-quality results, pumping information and a site-specific construction estimate in hand.

What a new well costs in Holly Hills, CO

How this is built: the median permitted depth here times the per-foot range for this ground, plus the normal system costs. A lot at the 75th-percentile depth (57 ft) would run roughly $8,850–$15,990. See the full Colorado well cost guide.

Counts come from EPA, USGS and state datasets layered on the Colorado Well Finder map. A count is not a verdict on any one well; it tells you what to test for.

Buying land near Holly Hills? Know what it costs to build before you buy the dirt.

A listing photo can't tell you whether a lot is a dream or a money pit. Two parcels near Holly Hills can carry the same asking price while one needs an $80,000 driveway and a $45,000 engineered septic the other doesn't. The well numbers on this page are the start of that answer. A Tri-Lakes Site Feasibility Report is the rest of it: a licensed general contractor, excavator and septic installer reads the parcel the way we would if we were about to build on it, and puts the real cost in writing before your money is committed.

Spend a little to know. Or gamble a lot to guess. Realtors sell the view and inspectors look at houses that already exist. We're the people who'd build it, so we catch what quietly turns a "great deal" into a budget disaster: bad access, buried rock, steep grade, soil that won't pass for a normal septic, water that's a fortune to reach. And if the lot is good, you've already got a builder ready to do the work, driveway to drywall.

• Instant Online Report, $99 — type the address and get a buildability read on the spot: parcel, terrain and slope, soil and septic outlook. Cheap enough to run on every lot you're shopping.
• Desktop Report, $500 — a contractor's from-the-desk feasibility read: Regulation 43 and county code, GIS parcel data, terrain, flood and drainage, soil and septic viability, setbacks and buildable envelope, nearby well depths from our 591,000-well database, the likely driveway route, and a preliminary site-development cost breakdown.
• On-Site Report, $2,000 — everything above, then boots and a drone on the actual ground: house pad and septic zone located, access and winter conditions checked, rock and soil observed in person, a 15 to 20 page written opinion you can hand a lender or seller. Credited toward your project if you build with us.

Under contract, comparing parcels, or a realtor with a rural listing whose buyers keep asking "what will it cost to build here?" This is the due-diligence step almost everyone skips, and the one that saves the most.
