Re: Angel Ranch Site CSRS Job No. 212161.012
Dear Mr. Cavanaugh:
According to the FEMA Flood Insurance Rate Map (FIRM) panel no. 2201400260C of Pointe Coupee Parish, Louisiana, effective November 16, 1995, the Angel Ranch property located 4,100 feet east of the intersection of Louisiana Highway 10 and Louisiana Highway 420 is located in Flood Zone “A” (no base flood elevations determined). In addition, according to the FEMA Preliminary DFIRM map provided on the LSU AgCenter website (http://maps.lsuagcenter.com), the site is located in Flood Zone “A”. A determination was requested from the Flood Plain Administrator, who determined a BFE of elevation 32 feet (determination attached).The LiDAR contours downloaded from LSU’s ATLAS site indicate that the site ranges in elevation from 25 feet to 39 feet, however, the majority of the developable property on the site is at elevation 32 feet. In order to raise twenty-five (25) contiguous acres to one foot above the BFE of 32 feet, approximately 40,500 cubic yards of in-place select fill will be required, thus bringing the twenty-five (25) contiguous acres to an elevation of 33 feet. The estimated construction cost for importing select fill embankment is $607,500 and $400,000 for suitable embankment material excavated on-site. Alternatively, a building can be raised above the base flood elevation (BFE) of 32 feet without raising the elevations of the paved and unpaved surfaces at a potential cost savings. The estimated construction cost per square foot to raise a slab on grade building pad to the BFE of 32 feet with select imported material is approximately $0.60 per square foot of building. Please note this estimate does not include engineering, required rights of way, environmental impacts, or operation and maintenance costs. This cost estimate was prepared with the best information available at the time of certification. The actual costs can vary based on the availability of material, site conditions and labor availability. This plan can be executed within a reasonable timetable of 18 months or less based on preliminary engineering judgment.
