Hawai'i County Code. A culvert and related drainage improvements will be constructed within the AE designated area (Splitway #2) to allow for a road connection between the northern and southern sections of the property. A Conditional Letter of Map Revision (CLOMR) to allow for this current improvement and adjustments to the FIRM has been submitted for review and approval by the FEMA. The applicant has prepared two (2) construction plans: 1) DOT Drainage Culvert Improvements, and 2) Picalani Makai Flood Channel which were developed and coordinated to address the road and drainage requirements of the project area. Currently, there is an 8 -foot wide pipe that crosses the extension of the Queen Ka` ahumanu Highway in the vicinity of the project site. This DOT installed system is undersized, therefore the DOT subsequently approved the DOT Drainage Culvert improvements plan that recommends a bigger culvert (20 -feet wide) and a 40 -foot wide concrete U-shaped channel from the Highway into a 2 -acre, 25 -foot deep retention basin near Kuakini Highway. According to the applicant, a culvert and related drainage improvements will be constructed within the AE designated are to allow for a road connection between the northern and southern ends of the property. The applicant acknowledges that there may be and added level of impervious surface resulting from the proposed development, therefore, drywells or similar types of accommodations will be implemented, subject to the review and approval of DPW and the DOH via the Underground Injection Control (UIC) and National Pollution Discharge Elimination System (NDPES) permit process. 27.
