Griffin SUBJECT: REQUEST FOR RENEWAL AND MAJOR MODIFICATION TO CAMA PERMIT #100-80 DATE: February 3, 1989 This office has received a request to renew and modify CAMA permit #100-80 issued to the Town of Manteo on August 28, 1980. This permit authorized the renovation of the downtown waterfront of Manteo. Included in this authorization was the construction .of a 12' wide 'boardwalk along Dough's Creek, three piers extending into Dough's Creek, a gazebo, and a number of mooring slips. Currently the Town is requesting a major modification to their permit, including the following: (1) Extending the 12' wide boardwalk beginning at the water-treatment discharge pier and running approximately 280' along the shore then spanning approximately 2201 across coastal wetlands to an existing parking lot on Fernando Street. An opening in the proposed boardwalk will be left for the haulout and repair of the Elizabeth II. The coastal wetlands to be crossed by the boardwalk consist of Juncus roemerianus, Spartina patens and scattered Iva sp. and Baccarus sp. (2) Constructing a 5' wide by 124' long seaplane pier to extend out from the proposed boardwalk. The property over which this would cross does not belong to' the Town of Manteo; however, the Town is negotiating to purchase or lease the property. A solid breakwater is proposed along the 24' "L" end and down 20' of the main pier. This is to protect seaplanes from wave action while docked. (3) Constructing a 300' long by 10' wide pier to extend out from the existing water-treatment discharge pier. A 60' by 10' "T" is proposed at its waterward end. This proposed pier would parallel piers north of.it along the Manteo waterfront. MEMORANDUM -2- ANTICIPATED IMPACTS Approximately 2890 square feet of coastal, wetlands will be covered and shaded by the elevated boardwalk and seaplane dock. The proposed 300' long fishing pier will extend beyond the --established pier length in Dough's Creek and may restrict navigation. , CAMA REVIEW The proposed modifications are consistent with the Manteo Land Use Plan. /yll cc: P.
