Re: Rolling Sunrise Subdivision Remand Order Response
Related Application Number: 11PLN 18840 SUB
This memorandum addresses the Hearing Examiner's order contained in the Remand Order
dated October 20, 2014.
(1) Documentation of the application's compliance with Minimum Requirement 1
through 10 of the state Department of Ecology's 2005 Stormwater Management
Manual for Western Washington.
Browne Wheeler Engineers, Inc. submitted Revision 1 to their preliminary drainage plan,
attached. The revised drainage plan, dated May 11, 2015 discusses how Minimum
Requirements I through 10 will be met. In addition, Browne Wheeler submitted a memo,
dated November 6, 2014 regarding soil infiltration rates at the Rolling Sunrise Subdivision.
(2) A limited scope Traffic Impact Assessment shall be performed focused on
defining the sight distance requirements at the locations of the project's two
proposed connections to the City's public road network, assessing whether such
requirements will be met under existing conditions, and proposing mitigations to
correct any identified deficiencies.
A limited Traffic Impact Assessment was completed by Heath & Associates, Inc. The
findings of the assessment are included in their letter to Janelle Hitch dated May 26, 2015,
attached. The findings and recommendations indicate the access points can meet sight
distance requirements. Additional conditions, based on the recommendations from Heath &
Associates are proposed below.
(3) A written stipulation between the City and applicant shall be negotiated
identifying the various improvements and maintenance activities as proposed
within this proceeding for achieving a minimum 12 feet in driving width and 13.5
feet of overhead clearance on both Sunrise Drive and Hyla Avenue; the
responsibilities for the implementation of these measures; and an overall timeline

containing applicable deadlines synchronized with the anticipated stages of plat
development (including transport onsite of modular units).
With the following proposed conditions added to the subdivision permit, improvements and
maintenance activities on Sunrise Drive and Hyla Avenue will be designated to the developer
in an appropriate timeframe to the proposed plat development. The conditions are:
1. Prior to site work the applicant shall clear vegetation from the site access points at Hyla
Avenue and Sunrise Drive out 170 feet along the sides of the roadway to achieve a
minimum of 12 feet driving width and 13.5 feet of overhead clearance. The 170 foot
mark shall be measured and clearly marked for the duration of the project, inspection
and approval by the City must be completed before further work may commence.
2. The applicant shall maintain the site distance clearance of 170 feet along the roadways
for the duration of construction activities. Monthly inspection reports shall be provided
to the City by the applicant showing that sight distance is being maintained.
3. Signing as recommended in the report by Heath & Associates, Inc. dated May 26, 2015,
shall be installed prior to site work.
4. A turnout meeting the City of Bainbridge Island Standard Detail 7-067 shall be installed
on Sunrise Drive. The location and design of the turnout will be included in the plat
utility application provided after preliminary subdivision approval. The location will be
reviewed by the City and the City's transportation engineer consultant to ensure the
location corresponds to sight distance and safety needs along Sunrise Drive. The turnout
shall be installed prior to the submittal of any building permit application. Verification of
the turnout shall be provided with the first building permit application.
Maintenance of all of Sunrise Drive and Hyla Avenue will revert to the City after completion
of all construction activities at the site. The City annually inspects the roadway condition
and conducts vegetation removal to maintain 12.5 feet in driving width and 13.5 feet of
overhead clearance.
