The site is accessed by a short <br /> driveway from CR120. I am interested in exploring the possibility of converting the adit into a wildfire <br /> fighting water cistern. I have explored the adit through the closure culvert, but further investigations <br /> can only safely occur with improved access to the adit. <br /> The existing closure culvert (36") will be removed, and the rock conditions analyzed to determine <br /> whether a larger (60-72") corrugated metal culvert or traditional timbered portal collar would be <br /> most appropriate. The larger adit access would extend further than the existing culvert to allow for <br /> better backfilling above the culvert. If desired, the existing closure culvert could be returned to the <br /> DRMS for future use. <br /> If the exploration reveals that adit could serve as a water cistern, a partial wall would be built to <br /> create a cistern behind the wall. It is not desirable to fully bulkhead and stop the water flow from <br /> the adit. Plumbing to provide access to the cistern would be installed to meet the needs of the local <br /> fire district for their water tenders. At this time, a design cannot be made for the wall. It is <br /> anticipated that the wall would be concrete cast in place and tied into the surrounding rock by rebar. <br /> The water flowing from the portal has been sampled and sent to CDPHE. The laboratory results <br /> are attached. <br /> Regards, <br /> Benjamin H.
