INFORMATIONAL MEMORANDUM

Mayor Haggerton
Utilities Committee
FROM:
Bob Giberson, Public Works Director 4 fi
By:
Ryan Larson, Senior Engineer
DATE:
May 11, 2012
SUBJECT:
2012 Annual Small Drainage Program
Project No. 91241201, Contract No. 11.151
Design Supplemental Agreement No.1
ISSUE
Approve Supplemental Agreement No. 1 to Contract No. 11 -151 with KPG, Inc. to design additional project sites for the 2012
Annual Small Drainage Program.
BACKGROUND
The 2012 Annual Small Drainage Program included relining pipes at Site 2 Wells Trucking and Site 4 Ryan Hill Pipe Repairs.
Neither of these projects was approved by the Washington State Department of Fish and Wildlife (WDFW). The WDFW Area
Biologist would like to see Site 2 4 upgraded to provide fish passage or day lighted. In addition, a project on S 150th St,
between 42nd Ave S and Tukwila International Blvd, that was to be constructed in 2012, has been delayed due to roadway width
concerns.
DISCUSSION
Delaying the S 150th St project and cancelling the two pipe relining projects leaves approximately $200,000.00 in construction
funds available for other project sites in 2012. To avoid delaying other needed projects, staff reviewed the Small Drainage
Project List to determine if additional projects could be constructed this year without delaying the construction process. Three
projects were selected which do not involve outside permitting or complicated design aspects that could be quickly designed
and added to the 2012 construction schedule. These projects are; Site 6 S 107th St Drainage Extension, Site 7 52nd /53rd Aves
S Drainage Extension, and Site 8 S 114 St Drainage Crossings.

Scope of Work
April 9, 2012
KPG
The purpose of this scope of work is to add mapping, design, and SEPA checklist
documentation for the following project sites to be included in the 2012 Annual Small
Drainage Program:
Site 6: S.107 th Street Drainage Extension
Extend drainage from S 107 Street to Beacon Avenue S and eliminate
ditch on the south side of 107 to the extent feasible. This project is
necessary in advance of the overlay of S 10 and Beacon Ave that is
scheduled for 2013.
Site 7: 52 53 Ave S Drainage Extension
Extend a 12" Storm Drain from the existing 53 Avenue South to a
ponding area on the north end of 52 Avenue South via S 142 Street.
The ponding area overflows into private property during heavy rain and no
formal collection system is available on 52 or 142 nd
Site 8: S114 th Street Drainage Crossings
Provide drainage crossings at up to 3 existing catch basin locations to
accommodate the overlay of S 114 Street, which is scheduled for 2013.
These projects have been added due to permit complexities with Site 2 (S 128
Street/Wells Trucking) and Site 4 (Ryan Hill Pipe Repairs) of the original scope
authorization. Washington Department of Fish and Wildlife will not grant an HPA for the
portions of these projects that lie on private property without full fish passable
compliance. The portions of these sites that are not permittable are deleted from the
2012 Small Drainage Program.
Work on these projects shall include any necessary survey, alternative analyses,
quantity estimating and cost estimating to complete the projects. Surveyed base maps
and horizontal utility locations will be provided for all sites. Right of way will be indicated
on the base maps based on available assessor information.
The Consultant shall incorporate these projects into the SEPA checklist for the 2012
Small Drainage Program.
