From the Douglas County News Press (Rhonda Moore):
The county planning staff recommends the county approve two options for the developer to choose from, one of which could result in construction of a 22,500 acre-foot water storage reservoir on nearly 430 acres.
Neighbors decry the proposal, with concerns the dam poses a potential safety hazard and will destroy mountain views, natural habitat and property values…
Ventana Capital proposes Penley Ranch as a development of more than 35 five-acre lots surrounding a non-recreational reservoir, which can provide a water storage solution for area water authorities. They came to the county with two options, a smaller, 14,000 acre-foot reservoir covering 292 acres, or the larger reservoir covering about 430 acres…
The planning staff recommends approval of both options, allowing the developer to decide which of the two will move forward. Among the conditions of approval are recommendations to perform detailed geotechnical and geologic investigations, provide the appropriate federal and state permits and comply with U.S. Fish and Wildlife Service requirements for the Preble’s Jumping Mouse. The dam site is identified as a potential habitat for the endangered mouse, according to a referral response from the fish and wildlife service. Another referral agency, the Colorado Geological Survey (CGS), responded with concerns that the dam is proposed on a site underlain by a complex series of faults.
Karen Barry, geological engineer with the CGS, says while the existing geotechnical report addresses whether the site soil can support embankments, further investigation can address potential hazards. “It is likely that geologic hazards and soil constraints can be mitigated,” Berry writes in her Jun 16 referral agency response. “Currently the application does not adequately identify or provide plans to mitigate such hazards.”[...]
The planning commission public hearing for the Penley Dam application continues at 7 p.m., Jan. 10 in the commissioner’s hearing room at 100 Third St. in Castle Rock.
