Collins, CO Drainage Memo Dear Mr. Mogen, Lot 191, Southmoor Village, Seventh Filing is an existing 8,569 square foot developed residential lot. There is an existing 2,785 square foot two-family dwelling on site that will be demolished due to fire damage. Please refer to the attached Improvement Survey Plat by Majestic Surveying for existing conditions. This project will consist of demolishing the existing 2,785 square foot two- family dwelling and replacing it with a proposed 3,182 square foot two-family dwelling. The minimal amount of grading will be limited to this lot and around the 3,182 square foot two- family dwelling and the change in grades will be minimal. Please refer to the attached Grading and Drainage Plan by Shear Engineering Corporation for the existing and proposed lot drainage patterns and grading detail. The existing drainage patterns will not change, and the lot runoff will drain as it historically has, to the north and east, with no adverse impacts to the adjacent properties. With the attached Improvement Survey Plat, the existing structure has a finished floor elevation of 4992.95'. The proposed finished floor elevation of the new structure with the attached Grading and Drainage Plan is 4993.48', a raise in finished floor of 0.53'. The final site impervious areas have been tabulated on the Grading and Drainage Plan with the existing and proposed impervious area summary table. With these proposed improvements, the impervious area decreases by 321 square feet, which is approximately a 4% reduction in impervious area. With these proposed improvements, stormwater quality treatment is provided by disconnected impervious areas and directing the downspouts into the landscaped areas. There are a total of two (2) downspouts, and they are on the front of the proposed two-family dwelling, and they drain toward the street into the landscape areas on the north side of the proposed structure. Due to the mono-slope roof, there are no downspouts on the south side of the proposed structure. If you have any questions concerning this drainage memo or its attachments, please call us at (970) 226-5334. 4836 S. College, Suite 12 Ft. Collins, CO 80525 (970) 226-5334 Fax (970) 282-0311 www.shearengineering.com PAGE 2 November 8, 2022 Project No: 3267-01-22 Re: Lot 191, Southmoor Village, Seventh Filing (909 Camelot Court); Ft.
