HomeMy WebLinkAbout1984 Villages of Lake Delores Site Plan (Box 10 #28) (21 VILLAGES or LAlm DOL ORF S CONCEPTUAL DRAINAGE PLAN BACKGROUND - The site is a working sand sine, approximately 17S acres and is located along the sand ridge about one mile North of Mabasso. The Northern section of the property actually cuts across the sand ridge which has been lowered from elevation 40 to about elevation CO. The major feature of the fpoject is the lake which is being excavated as part of the lining operation. SOILS - The soils in the area range from sandy well drained very permeable ridge sand to flat, poorly drained sands in the flatwoods to the west and along the railroad. DRAINAGE SYSTEM - The project will be divided into two main drainage basins. The main drainage basin will serve the residcntal portion of the site and will drain to the lake. The second basin will be the area parallel to the railroad. This area will be served with retention swales and drainfields. Some of these improvements would be installed as part of the subdivision construction process with additional improvements being constructed in conjunction with the actual commercial development. The lake is sized to retain the runoff from a 25 year P4 hour storm (F' = 8.64 in.), however in the event of a worse storm event the system would overflow through the stars drain system of the second drainage basin to an existing outfall along the railroad tracts. The total system will he designed to reduce the runoff rate from the project to a level which will not exceed the capacity of that existing outfall system.
