Chapter 3 ⎯ Affected Environment3.1.5.2 Dillingham Military ReservationLand uses at the 664-acre DMR include an airfield and associated roadways, bunkers, and earthenairplane hangars; approximately 354 acres suitable for maneuver and field training; 107 acres are developedwithin the cantonment area; and the remaining lands are located on steep slopes of the WaianaeMountains (USARHAW and 25 th ID [L] 2006). Most of DMR is within the state-designated AgriculturalDistrict but is not used for agriculture. The airfield portion of DMR is within the SpecialManagement Area (SMA). SMAs are lands within the shoreline setback, which is currently 40 feetfrom the shoreline, although some setback boundaries extend farther inland. SMAs are designated formanagement that is more intensive and actions within the SMA may require an SMA use permit fromthe local planning commissions.There are no live-fire activities, designated impact areas, or associated surface danger zones on DMR(USARHAW and 25 th ID [L] 2006). Ammunition is restricted to the use of blanks, and non-aerialsmoke is allowed in designated areas. Portions of the reservation, including the runway and parkingarea, have been leased to the Hawaiian Department of Transportation (HDOT) since 1983 for civilianlight aircraft operations and support (USARHAW and 25 th ID [L] 2006).Public recreational uses at DMR include hunting, glider plane operation, parachuting, sky diving,hang gliding, and hiking. Glider plane operation, parachuting, sky diving, and hang gliding are allowedin designated areas associated with the airfield. The 2.3-mile Kealia Trail can be accessedthrough the western portion of DMR (USARHAW and 25 th ID [L] 2006). This trail allows nonmotorizedbiking and is open to the general public.The land surrounding DMR is generally undeveloped and includes state-designated Prime agriculturalland to the east, beaches to the north, and some residences to the northeast. The Kawaihapai reservoirand associated pumping station and aqueducts are east of DMR (USGS 1998). Land south of DMR ismountainous and includes a state hunting area to the southwest. Land uses to the west include an inactivequarry, the YMCA’s Camp Erdman, and the military’s Camp Kaena. The Pacific Ocean is tothe north.The Dillingham Trail would connect the SBMP and DMR using a southeast to northwest alignment.The trail alignment would require a 55-acre easement along agricultural roads and undeveloped lands(USGS 1998, 1999b). The land surrounding Dillingham Trail is generally agricultural or undeveloped.The trail crosses the SMA as it passes to the north and west of Thomson Corner, a residentialsubdivision (State of Hawaii 2002a).3.1.5.3 Kahuku Training Area and Kawailoa Training AreaLand uses on KTA include tactical maneuver training and KLOA is primarily used for maneuver,helicopter, and mountain/jungle warfare training.
