The proposed stormwater management system will consist of man-made lakes and a mitigation area hydraulically connected to the C-11 canal via Ditch 3. The stormwater will be controlled to assure that the minimum roadway elevation is at or above the ten-year one-day storm event and the finished floor elevations shall be constructed at an elevation higher than the 100-year three-day storm stage. The primary drainage system will consist of catch basins and drainage pipe connected to the lake/canal system. The outfall catch basins will be provided with pollution control devices to mitigate the point discharge of pollutants into the lake system. The water management system shall be designed to meet the criteria of the South Florida Water Management District and the City of Weston Water Control District.
The subsurface at this site generally consists of rock overlain with a layer of muck two to four feet thick. The rock in this area is normally very hard and difficult to excavate, it is anticipated that the rock will be blasted then excavated using conventional methods. Muck will be removed in lot and roadway areas and structural fill will be placed to bring these areas to grade.
The stormwater will be controlled to assure that the minimum roadway elevation is AT OR ABOVE THE GREATER OF 6.9 N.G.V.D. and the ten-year one-day storm event and the finished floor elevations shall be constructed at an elevation AT OR ABOVE THE GREATER OF 8.0 FEET N.G.V.D. and the 100-year three-day storm stage.
