Page 10 of 10 011M. � I���Te o I S PCN attachment for Lake Waccamaw BAA B -3a Site is an existing public boating access area (BAA) owned and operated by NCWRC. The site has 2 concrete boat ramps which are in poor condition that were installed in 1975. The shoreline is bulkheaded with wood bulkhead. The shoreline was first bulkheaded in 1955 and the existing bulkheads and docks were constructed in 1980. The site has an unorganized gravel parking lot which does not delineate parking or have ADA- compliant parking and pathways. The maneuver area in front of the ramps is not sufficient to allow users to align vehicles to launch /recover boats without driving into NCDOT ROW. Land use in this area is generally residential and recreational. The lake is owned by Lake Waccamaw State Park. Parcels directly adjacent to the BAA are developed residential properties. B -3d The purpose of this project is to improve public boating access to Lake Waccamaw by renovating the existing facility. The poor condition ramps will be replaced and aligned in such a way that provides adequate maneuver area for users entirely outside of NCDOT ROW. The parking lot will be improved with delineated parking for both single vehicles and vehicles with trailers as well as providing ADA- compliant parking. B -3e This project will include the demolition of existing ramps and fixed docks. 2 new concrete ramps will be constructed in the same shoreline location as the existing. The concrete ramp slabs will be poured on high ground. The ramp stone base will be constructed on grade using an excavator. A bulldozer will push the slabs into place after they have cured and live concrete will not come into contact with the lake waters. High ground portions of the ramps will be formed and poured in place. An 8 -wide floating dock will be installed between the 2 ramps and help users launch and recover their boats. An 8' dock width is requested to safely serve the use of both ramps simultaneously as well as for general safety and mobility issues. The 8' width has proven to be more stable in situations with boat wake or wind - driven waves in comparison a 6' -wide dock which can be quite wobbly in wavy or choppy conditions. The increased steadiness of the 8' -wide dock better serves users with disabilities, users limited mobility for any reason, and users carrying gear such as coolers. New bulkheads will be installed waterward of existing bulkheads. With exception of a 46' -long section that will be flared further into the water to square up the ramps excavation area, the new bulkheads will be 2' in front of existing. Squaring up the shoreline improves safety of the upland parking lot by creating geometry that meets design standards for vehicles pulling trailers in the parking aisles and ramp maneuver area. Current upland geometry does not meet design standards and results in vehicles utilizing DOT ROW and roadway to maneuver.which is a safety concern. Bulkhead vinyl sheets will be driven with a vibratory hammer. The parking lot construction will involve supplementing the existing gravel areas to construct appropriate base and then paved with asphalt. The property was originally bulkheaded in 1955; Permits are unknown. The current ramps were constructed in 1975; permits are unknown. The current fixed docks were constructed in 1980; permits are unknown. Maintenance dredging of accumulated sediment was authorized under an RGP 277 in June 2010 as action ID 2010 - 00844. D -1a Several site design alternatives were evaluated and ultimately the chosen design replaced the existing ramps in the same shoreline location to minimize area of impacts by excavating and filling in the same place instead of 2 different shoreline locations. Using the existing ramps location also is aligned with previous maintenance dredging so that a dredging would not be anticipated in a new location in the future. Having the ramps share a single, center floating dock results in less shaded area compared to each ramp having its own dedicated dock. Designing the bulkhead directly in front of existing instead of exactly in existing allows the existing bulkhead to remain in place and not expose any bare earth shoreline that could potentially erode and cause siltation during the construction process. Paving the renovated parking lot instead of leaving it gravel will reduce the potential for sediment runoff.
