Black Forest Fire Protection Districtreview 1Oct 5, 2026

Black Forest Fire Protection District has no objection to the Raff Subdivision one-lot final plat as described in the Letter of Intent. This comment is limited to establishing the legal lot and does not constitute approval of the proposed residential addition, existing commercial stable, or other structures or uses. The proposed residential addition and any future development or change of use shall be submitted to the District for review of applicable fire access, firefighting water supply, and fire protection requirements.

Colorado Geological Surveyreview 1Sep 28, 2026

The site does not contain steep slopes, is not undermined, and does not contain, nor is it exposed to, any geologic hazards that would preclude the existing and proposed residential use. Per Entech’s soils and geology study (Entech Engineering, August 7, 2026), the geologic conditions that will pose constraints on the site include artificial fill, potentially expansive soils, potential seasonal shallow groundwater, ponded water, and the potential for elevated radon levels. However, Entech’s soils and geology study did not include borings; therefore, the depth to groundwater and the presence of potentially expansive soils were not determined. Water was observed in the pond that is located in the center of the site. This pond is designated as a wetland area and, per Entech’s report, will be avoided by construction. CGS offers the following comments and recommendations. 1. As a condition of approval, the geologic hazards and mitigation measures discussed in Entech’s report should be included in the final plat. The final plat should also reference Entech's report. 2. Per the letter of intent (Land Development Consultants, Inc., August 7, 2026), an addition to the existing single-family residence is planned. Prior to the building permit application, a site-specific subsurface soil investigation consisting of drilling, sampling, lab testing, and analysis will be needed to characterize soil and bedrock engineering properties such as density, strength, water content, and swell/consolidation potential. These results will be required to evaluate potentially moisture-sensitive (expansive and collapsible) soils and expansive claystone bedrock; determine depths to groundwater and bedrock; verify the feasibility of below grade levels, if planned; and provide earthwork, foundation, floor system, surface and subsurface drainage, and pavement recommendations for design purposes. 3. Entech states (page 6), “areas where high subsurface moisture conditions are anticipated periodically, a subsurface perimeter drain will be necessary to help prevent the intrusion of water into areas located below grade.” An underdrain system should be allowed ONLY if it can gravity discharge to a daylight outfall or is connected to an existing underdrain system that gravity discharges to a daylight outfall. Individual foundation perimeter drains are intended to handle small amounts of intermittent, perched water and may NOT be used as the sole mitigation of persistent shallow groundwater conditions.
