LDC 6.13.8.B(5) - Stormwater Conveyance Criteria
CODE states Drainage easements. All drainage swales to facilities or underground stormwater conveyance systems shall be within drainage easements, except where rights-of-way are provided. Drainage easements shall be a minimum of 20 feet in width.
APPLICANT requests a waiver to allow a 10-foot drainage easement for existing stormwater piping between Lots 9-10 Block P. The 10-foot drainage easement between the lots is in conformance with the approved PUD, preliminary plat, and improvement plans. This is a private subdivision maintained by the POA. This project has been reviewed by the county through 3 submittals, and now the county is asking for 20-foot drainage easement. The 18-inch drainage pipe is centered on the lot line and has approximately 10 inches to 42 inches of cover over the pipe. This pipe run is to convey a limited area of runoff from the rear 1/2 of 14 lots. The pipe is designed to convey 5.22 cubic feet per second.

CODE states Drainage easements. All drainage swales to facilities or underground stormwater conveyance systems shall be within drainage easements, except where rights-of-way are provided. Drainage easements shall be a minimum of 20 feet in width.
APPLICANT requests a waiver to allow a 10-foot drainage easement for existing stormwater piping between Lots 27-28 Block O. The 10-foot drainage easement between the lots is in conformance with the approved PUD, preliminary plat, and improvement plans. This is a private subdivision maintained by the POA. This project has been reviewed by the county through 3 submittals, and now the county is asking for 20-foot drainage easement. The 18-inch drainage pipe is centered on the lot line and has approximately 36 inches to 54 inches of cover over the pipe. This pipe run is to convey a limited area of runoff from the rear 1/2 of 5 lots. The pipe is designed to convey 1.87 cubic feet per second. The alternative to approving this waiver request is to permit the stormwater runoff from the rear 1/2 of these 5 lots to drain to the SW 49th Avenue inlets located on the east side of the multi-use path. The existing inlets and conveyance system are designed to accept the pre-development runoff from Basins 1-3 and 1-4, per the SW 49th Avenue Phase 2 plans. The permitted runoff 100-24 volume is 49,778 cubic feet with a combined discharge rate of 8.20 cubic feet per second. The new proposed condition will generate 10,126 cubic feet with a combined discharge of 2.46 cubic feet per second.
