Box 580 Fort Collins, Colorado 80522 - 0580 Re: 1209 Mountain Home Drive, Fort Collins, Colorado Dear Mr. Barber, This letter is being provided to acknowledge that a Grading Certification has been completed on the property at 1209 Mountain Home Drive and has been found to generally conform with the City approved drainage and grading plan for the property that was completed by Northern Engineering. As designed, the front portion of the walkout lot drains away from the home and into the gutter of Mountain Home Drive. Runoff is then directed eastward in the gutter until reaching a storm inlet located at the end of the cul de sac. The inlet discharges through an 18" diameter R.C.P. that outlets into the adjacent detention pond. The backside of the lot drains in a southerly manner, away from the house and into a drainage swale along the south lot boundary. The swale conveys runoff to the neighboring detention pond located on Tract C. Several straw wattles have been previously installed within the swale to reduce waterborne sediment from being carried into the detention pond. The owners began site landscaping last summer. (A copy of the landscape plan is attached for clarify and to demonstrate that drainage for the property will not be negatively impacted.) A sand volleyball court is proposed at the east side of the lot and excavation of the court has already been conducted. As a means of providing adequate drainage until the volleyball court is completed in spring/summer of 2008, a perforated 4" diameter HDPE underdrain was installed to carry stormwater out of the excavated area and discharge it into the drainage swale along the south end of the lot. The pipe was wrapped in a filter "sock" and covered with pea gravel to eliminate any sediment from passing into the pipe and being carved downstream. If you should have any questions or desire additional information, please feel free to contact me at 970-217-2762. Respectfully submitted, ;lftQe��� W07 Cameron W.
