Description: This layer contains 20ft and 50 ft buffers from the centerline of any ditch included in the Boulder County Ditch and Reservoir Directory. This data was produced to aid the Community Planning & Permitting department in determining if structures are being proposed within a 50 ft setback from hte ditch centerline, as specified in the Lot, Building & Structure requirements for each zoning district: "From an irrigation ditch...50 feet from the centerline of the ditch. This requirement only affects structures built after October 10, 1996. The setback may -with County concurrence- be reduced in accordance with a letter from the applicable ditch company establishing a different setback, but in any event shall not be less than 20 feet from the ditch centerline."Irrigation Ditch is defined as "A long narrow excavation dug in or placed on grade for carrying water which is listed in the Boulder County Ditch and Reservoir Directory".Feature geometry is based on the Boulder County Ditch and Reservoir Map and the Streams_Ditches dataset, maintained by Boulder County Parks & Open Space, as well as the Boulder County Ditch and Reservoir Directory, maintained by the St. Vrain & Lefthand Water Conservancy District.
