VARIANCE REQUEST to RENTON FIRE AUTHORITY
SUMPTER SHORT PLAT
April 4, 2019
The applicant, Don Sumpter, proposes a private road in excess of 300 feet with a hammerhead type
turnaround to serve six lots. The applicant requests a variance for the typically required 90-foot diameter
cul-de-sac type turnaround with mitigation, including a hammerhead turnaround and fire sprinkler for all six
homes.
The project is designed to maximize tree retention at the perimeter of the site, including a buffer of trees
along 156th Avenue S.E. In an effort to retain trees, reduce connections to a collector arterial, and to
balance the impact of the new public roadway that will bisect the long narrow site, a shared driveway with
a sidewalk and hammerhead turnaround serving six lots is appropriate for this short plat.
Emergency vehicle access is adequately provided by the 20-foot wide fire lane and the hammerhead
turnaround. We have discussed the hammerhead proposal with Renton Fire Marshal staff and received
general concurrence that the hammerhead would be acceptable if the future homes are equipped with
automatic fire sprinkler systems. The applicant accepts a condition to automatic fire sprinkler systems for
all six future homes accessed from Tract B as mitigation for the long shared driveway and hammerhead
turnaround.
