The lots to the west and east of the subject property have been developed and have existing landscaping. The grade away from the northwestern corner of the garage is less than 5%; the minimum grade away from the garage is 1.0%. A portion of the swale in the northwestern area of the lot is less than 1%. The swale is 0.5% and not near the structure. The swale flowline elevation near the northwestern corner of the garage is less than 6” below the adjacent finished grade of the garage. The swale along the western property line (common lot line with Lot 2) is inside Lot 3. Runoff from Lot 2 reaches the swale on Lot 3. The difference in elevations between the properties and existing landscaping necessitated the contractor to construct the swale inside Lot 3 and not on the property line. 2151 Yearling Drive Fort Collins, CO Lot 3, Block 1 Bucking Horse Filing Three Sheet G1 Scale: 1"=40' North
