About this file
This is a Preliminary Stormwater Pond Excavation Volume Assessment prepared by Brent Fulton Civil Engineering for Volusia County's proposed State Road 44 Motocross Development, dated January 23, 2026. The assessment evaluates five potential stormwater pond locations (DA-1 through DA-5) identified based on anticipated motocross track layouts and associated parking areas. Four pond locations (DA-1 through DA-4) are situated within upland areas, while DA-5 would require wetland impacts and corresponding mitigation. Each pond was evaluated assuming a total excavation depth of 15 feet. The analysis is supported by stage-storage calculation sheets, a potential stormwater layout map, and detailed elevation-to-volume data for each drainage area.
Excavation of stormwater ponds DA-1 through DA-4 is anticipated to generate approximately 129,452 cubic yards of fill material, with individual volumes of 38,245 CY (DA-1), 43,002 CY (DA-2), 29,643 CY (DA-3), and 18,562 CY (DA-4). Should the developer proceed with DA-5 and provide required wetland mitigation, an additional 148,906 cubic yards of fill would be available. All volume calculations presented are based on in-place (bank) quantities and do not account for swell, shrink, or compaction factors. The stage-storage data includes elevation profiles, surface areas in square feet and acres, volumes in cubic feet and acre-feet, and corresponding volumes in cubic yards for each drainage area, providing the developer with comprehensive excavation and fill yield information for project planning purposes.

NARRATIVE
A preliminary stormwater pond excavation volume assessment has been prepared for Volusia County’s proposed
SR-44 Motocross Development. The potential stormwater pond locations were identified based on the anticipated layout of the motocross tracks, and associated parking areas. With the exception of Drainage Area (DA-5), all proposed pond locations (DA-1 through DA-4) are situated within upland areas.
Construction of stormwater facility DA-5 would require wetland impacts and corresponding mitigation by the developer.
The estimated excavation volumes and resulting fill yield generated from the proposed stormwater pond areas are summarized in the accompanying stage-storage calculation sheets. Each pond has been evaluated assuming a total excavation depth of 15 feet. Based on the preliminary volume calculations, excavation of stormwater pond areas DA-1 through DA-4 is anticipated to generate approximately ±129,452 cubic yards (CY) of fill. Should the developer elect to proceed with excavation of DA-5 and provide the required wetland mitigation, an additional ±148,905 cubic yards (CY) of fill is expected to be available. Please note that excavation and fill yield volumes presented herein are based on in-place
(bank) quantities only and do not account for swell, shrink, or compaction factors.
