FROM: Daryl Grigsby, Director of Public Works
Prepared By: Manny Guzman, Engineer III
SUBJECT: STORM DRAIN REPAIRS AT JEFFREY AND CERRO ROMAULDO,
SPECIFICATION NO. 91181
RECOMMENDATIONS
1. Approve plans and specifications for the Storm Drain Repairs at Jeffrey and Cerro
Romauldo Project, Specification No. 91181.
2. Authorize staff to advertise for bids and authorize the City Manager to award the contract if
the lowest responsible bid for the Storm Drain Repairs at Jeffrey and Cerro Romauldo
Project is within the Engineer’s Estimate of $252,000
DISCUSSION
A large portion of the City’s storm sewer pipeline infrastructure is comprised of corrugated metal pipe
(CMP). In the 1960’s and 1970’s, CMP was the industry standard due to its inexpensive material cost,
ease of installation and projected 50-year design life. In the City’s experience, CMP has proven to have
a life of 20 to 30 years. CMP typically fails by friction from the action of flowing water with rocks and
sediment, corrosion, or both. Once the integrity of the pipe has been compromised, the pipe’s
surrounding soil becomes susceptible to piping (soil picked up by flowing water and carried away) and
the pipe will eventually collapse.
The proposed project will address a failing CMP drain system on Jeffrey Drive, Cerro Romauldo
and in easements over private property at 299 Cerro Romauldo. The project will install three catch
basins and approximately 325 linear feet of pipe and box culvert. The project will also reroute the
new storm drain system to stay completely within the Public Right of Way.
On March 1, 2005 Council received the Storm Sewer Management Plan and directed staff to pursue
CMP replacements with the goal of replacing all the City’s CMP within 50 years. The City’s storm
drain system is comprised of 70,000 lineal feet of pipe of which 22.4% are CMP. To date 4,000
lineal feet has been replaced. Measure Y funding is the primary funding source for this work and
for the next five years the annual CMP replacement effort is between $300,000 to $600,000 per
year.
CONCURRENCES
This project is exempt from environmental review since it is a maintenance and replacement project
and a Notice of Exemption has been filed through the Community Development Department.
