ISSUE
Award the bid for construction of the 2012 Annual Small Drainage Program.
BACKGROUND
The Small Drainage Program constructs drainage projects throughout the City that are too large for
City staff to complete, but are smaller than a typical capital improvement project. The projects
originate from citizen complaints and from maintenance staff and are compiled on the Small
Drainage Project List. Each year the projects are prioritized based on need, expense, permitting
requirements, and length of time on the list. The highest priority projects are then designed and
constructed.
The 2012 Annual Small Drainage Program will provide drainage improvements at eight locations
listed on page 2 of this memo. Project #2 includes lining a pipe within private property as part of the
Private Storm System Adoption Program. Project #5 is for flood protection work at Fort Dent Park
and funding will be reimbursed through the King County Flood Control District Opportunity Fund.
ANALYSIS
The 2012 Annual Small Drainage Program was advertised for bids on June 5 and 12, 2012. Four
bids were received and opened on June 19, 2012. The bids were checked, corrected, and tabulated.
