I ►�• �I � ��r.:��: ��. � :, ��J �� SITE INFORMATION AND LOCATION Lot 16 in Block 4 of Evergreen Park is a 39500 square foot lot which was platted in 1973. The lot is located on the west side of Blue Spruce Drive about 700 feet north of Conifer Drive. All streets and utilities in the area are existing. The lots to the south and west are developed and the lots to the north are vacant. EXISTING SITE CONDITIONS Lot 16 drains from.the west to Blue Spruce Drive on the east on a slope of 0.5 percent. There is no offsite drainage onto Lot 16. Lot 3, which is located directly west of Lot 16, has been graded to drain back to the west. Lot 17 on the north and lot 15 on the south both drain east to Blue Spruce Drive. Lot 16 is presently covered with fairly heavy vegetation. PROPOSED DEVELOPED DRAINAGE Lot 16 will be graded to drain to a detention pond located along the east side of the lot. The pond will be adjacent to Blue Spruce Drive and the pond outflow will be released into the west gutter of Blue Spruce Drive through a restricted orifice. Calculations of the allowable release rate, required detention volume and volume of the proposed pond are included on the included sheets. EROSION CONTROL Lot 16 is located in a moderate rainfall erodibility zone and in a moderate wind erodibility zone. The east two thirds of the lot will be covered by the detention pond paved parking and drives and by the building, The rear one third of the lot will be covered with a gravel storage area and by two storage buildings. A silt fence will be installed along the west curb of Blue Spruce Drive during overlot grading. A sediment trap will be placed over the detention pond outlet. Adequate wind erosion will be provided by the construction of the building and by the rainfall erosion control measures. All erosion control procedures shall comply with City of Fort collins Criteria.
