Discussion:
On July 24, 2007, City Council awarded the Buck Gully Wetlands and Maintenance
Road Repairs at 5th Street Project to McKenna General Engineering, Inc., at a contract
price of $344,823.60 and approved a contingency of $34,500. The contract has now
been completed to the satisfaction of the Public Works and General Services
Departments.
This project entailed the reconstruction of the maintenance road crossing Buck Gully
Creek that is utilized by the City's Utilities Department to access water main facilities.
This project also included design features to stabilize the streambed which has
experienced down - cutting that could threaten to undermine the new creek crossing or
possibly destabilize the canyon banks. As concrete -lined channels are no longer the
preferred alternative by the jurisdictional agencies, stabilization of the streambed is
being accomplished using different types of gabions (wire baskets filled with rock or

soil) that are then tied together forming a continuous structural element. This
environmentally - friendly building method has been viewed more favorably by the
permitting agencies since the City's successful Morning Canyon stabilization project.
The irrigation and planting of native California wetland and upland plant species has
been completed and the 120 -day plant establishment maintenance period has been
successfully completed as of July 24, 2008 when a final field inspection was performed.
On May 13, 2008, the City Council approved a budget amendment to appropriate an
additional $47,500 for the project. This appropriation increased the contingency from
10 percent ($34,500) to 24 percent ($82,000) to cover projected unanticipated
additional costs for this project. Unfortunately, the additional costs required to
complete the project was underestimated by $42,787.23. Most of these additional
costs are justified due to the difficulties experienced with constructing streambed
improvements during the winter (as required by the California Coastal Commission).

Original bid amount: $344,823,60
Actual amount of bid items constructed: 389,713.60
