The purpose of this agenda item is to solicit any additional comments and input on the
Phase A Report from the WRAB members and public. This agenda item is scheduled to
return to the WRAB on December 17, 2007 to request a Final Recommendation.
On October 15, 2007 WRAB meeting, staff presented the Fourmile Canyon Creek and
Wonderland Creek Major Drainageway Planning - Phase A Report - Alternatives Analysis
(Phase A Report). WRAB members may retrieve this information from their previous packet or
review the packet on the WRAB web site.
The Fourmile Canyon Creek and Wonderland Creek Major Drainageway Planning - Phase A
Report - Alternatives Analysis (Phase A Report) focuses on the development, evaluation, and
recommendations of alternatives to mitigate future flooding in both the Fourmile Canyon Creek
and Wonderland Creek flood hazard areas within the City of Boulder (City) and Boulder County.
The work was jointly sponsored by the Urban Drainage and Flood Control District (UDFCD)
and the City of Boulder, Colorado. The Phase A Report was prepared by the consultant Love &
Associates. The Phase A Report presents information regarding flood mitigation planning. City
staff has coordinated the flood mitigation planning with other objectives of the Greenways
Program and presented the report to the Greenways Advisory Committee.
The Phase A report evaluates a number of alternate drainageway planning concepts to mitigate
existing flood damages, taking into consideration the impacts of the spill flows from Fourmile
Canyon Creek to Wonderland Creek. The study is divided into two phases. The first phase
(Phase A) is the initial report that covers the hydrologic, hydraulic, and alternate evaluation
aspects of the project. The future, second phase (Phase B), will cover the preliminary design of
the selected alternates. A complete copy of the Phase A report is available at:
