Kamakana Street Improvements

'Ewa Beach, O'ahu, Hawai'i

Completed

2017

Belt Collins as prime consultant designed a new 2-lane City dedicable collector road with a 78-foot right-of-way serving industrial and residential parcels. The segment built is the first portion of the roadway which will eventually connect to Waikapuna Street. Included in the roadway design were 2 asphalt-paved travel lanes, left turn pockets and bike lanes in both directions, with curbs and gutters, 10-foot wide landscape strip with street trees, street lights, and 5-foot wide sidewalks along each side.  

Single-lane Roundabout

Bike Ramp

Kamakana Street is a residential roadway serving as an access to Coral Ridge and SEAbridge by Gentry Homes in ‘Ewa, O‘ahu. The approximate 1,800 foot long 2- lane roadway with left turn pockets and bicycle lanes, incorporates a roundabout at what is currently a 3-leg intersection. The roadway is located near the Honouliuli Wastewater Treatment plant entrance along Geiger Road, just west of the Coral Creek Golf Course. The new roadway was built to City and County of Honolulu subdivision street standards and includes the first new single lane roundabout designed on the island. Infrastructure installed within the roadway included water, sewer, drainage, electrical, lighting, irrigation, and landscaping.

As part of a Complete Streets initiative, the City and County of Honolulu asked Belt Collins to design a single-lane roundabout at the intersection with Hinakea Street. It was designed with a mountable center island for lager trucks and emergency vehicles and also included bicycle ramps just ahead of and right after the roundabout to allow bicyclists onto the sidewalk area, where they could navigate around the roundabout. This roundabout was the first private developer constructed single lane roundabout designed and dedicated to the City. Subdivision filing and National Pollutant Discharge Elimination System (NPDES) permitting services were also provided for the project, along with construction contract administration services.
