• <br />• <br />Plat Note Requirements <br />Adams County is now requiring a restriction on all gravel extra- <br />tion operations in order to provide for a procedure to be follow- <br />ed in the event a claim is made that an adjacent well is damaged <br />by,a mining operation. Since this is now a standard requirement <br />the applicant will comply and has provided such a statement. <br />However, the applicant feels this operation will cause no ad- <br />~ verse effects to shallow wells since no dewatering is taking <br />place. Plus, since four mining operations will be located adja- <br />cent to one another, ib may be extremely hard to pinpoint cause <br />and effect in the event some effect was encountered. <br />• Water Resources for Afteru~e . <br />The proposed afteruse is 13 homesites, 1 commercial lot, and a <br />large common lot consisting of the lake and shoreline. The <br />homesites and commercial lot will require water for inhouse use <br />~ and irrigated lawn. This water will be provided via a communi- <br />ty water system dependent on deep aquifers. The necessary well <br />permits have been applied for, and the accompanying water re- <br />port illustrates these aquifers have sufficient water to supply <br />~ the subdivision in conformance with state law. In addition, as <br />required by MLRB policies and state law, prior to homesite con- <br />struction (and even after for nonirrigated areas), water will <br />be necessary to establish growth and occasionally keep vegeta- <br />~ tion from dying during drought periods. Water for this pur- <br />pose will be supplied from shallow well water.ri,ghts. <br />I~ Drainage <br />The attached drainage report discusses historic and future run- <br />off conditions with relevant calculations. Presently there is <br />little exterior surface drainage entering the project site due <br />• to US 85 and irrigation ditches which traverse the area. in <br />addition, since the soils are very porous, often water falling <br />on the property and from adjacent land percolates into the <br />ground without leaving the property. What water does exit the <br />~ property, does so across Nome Street, 450 feet south of the in- <br />tersection of 132nd and Nome Street. <br />During and after excavation all runoff entering the excavated <br />areas will be retained in the lake and returned to ground water <br />~ recharge. The present drainage pattern will remain unchanged in <br />unexcavated areas adjacent to Nome Street and 132nd. Therefore, <br />the front yard of each homesite will drain in a historical man- <br />ner, but since this small amount of area is substantially less <br />~ than exists historicall drains a onto adjacent <br />y, g ~ property will <br />decrease. <br />• <br />
