SHELTON, WASHINGTON 98584
MEMORANDUM —Exhibit 1
TO: Melissa McFadden, PE
Deputy Director/County Engineer
FROM: Dave Smith, PE, Transportation Engineer
Loretta Swanson, Technical Services Manager
DATE: February 1, 2016
SUBJECT: Proposed Speed Limit Change — North Bay Road
Engineer s Report and Recommendations
Mason County Public Works received a Citizen Request to decrease the speed limit on a segment of
North Bay Road on May 4, 2015, by business owner Mr. David Spandl. A letter of concern by resident
Mr. Cizek was also received on October 19, 2015 requesting a speed limit reduction in the same vicinity.
Both cited high speeds and an increase in the number of accidents as the reasons for their requests.
This memo presents findings and conclusions to support a recommendation to extend the 35 MPH
speed zone from MP 0.25 to MP 0.35.
Recommendation
The current speed limit on North Bay Road. is 35 MPH from MP 0.00 to MP 0.25. This recommendation
extends the 35 MPH speed zone from MP 0.25 to MP 0.35, an approximate additional distance of 525
feet north. This is the section of road beginning at the intersection of SR-3 and going approximately
1,800 feet north. See attached vicinity map.
Public Works conducted an engineering study using the latest methodology and availabledata to
determine the safe speed. Current traffic volumes are 2026 ADT with 85th %Ile speeds of 47 MPH
southbound and 56 mph northbound. Accident history shows 5 crashes from January 2010 through
December 2015, within MP 0.00 and MP 0.25. All five appear to be speed or access related. Through
lanes are 2-12 foot ACP with no shoulders and a roadside ditch on each side
The road segment proposed for the speed reduction is within the Allyn UGA. An increase in land use
activity with the potential for more, the installation of two sub -standard commercial road approaches at
221 E. North Bay Road, several residential accesses, three crashes in 2015, and no shoulders support the
extension of the speed zone. The remainder of the road, beyond MP 0.35, should remain at the
currently posted speed of 50 MPH.
