RECOMMENDATION: City Council to consider approval of an engineering contract for Big Bear
Creek Erosion Assessment with Halff Associates, Inc. and an ordinance
appropriating the funds.
FUNDING SOURCE: Upon approval of the attached ordinance, funds will be available in the
Storm Drainage Fund in the estimated amount of $220,000.
BACKGROUND: Big Bear Creek has been experiencing erosion for many years. The latest
storms have destroyed or damaged three sanitary sewer aerial crossings
along the channel. Additional aerial crossings, bridges, trails, parks, public
and private property may be threatened by erosion and changes to the
Big Bear Creek channel.
Halff Associates, Inc. will utilize existing hydraulic and hydrologic models
and field observations to identity and evaluate existing erosion issues and
erosive potential along Big Bear Creek. The information will be prioritized
and collected into a format to create a stream asset management
program. This study will identify current and likely future areas of concern
along Big Bear Creek. This information will be utilized to create an erosion
protection plan.
The cost for engineering services will be $220,000. The cost of the
improvements is unknown, pending completion of the study.
Staff recommends approval.
