Bullock Lane Corrugated Metal Pipe (CMP), Replacement Project; and

DISCUSSION
Background
The City’s Storm Drain System Replacement program is an annual asset maintenance program
that addresses capital maintenance of drainage pipelines, culverts, and constructed drainage
channels and is aimed at replacing or reconstructing failed facilities and reducing flood risk and
the likelihood of property damage. Identifying and replacing failing storm drainage also ensures
that the City’s drainage system can adequately accommodate stormwater flows through the
City’s drainage network, thereby reducing flooding potential. A large share of the City’s storm
drainage infrastructure consists of Corrugated Metal Pipe (CMP), which no longer conforms to
City standards and must be replaced based upon frequent failure from corrosion. As CMP
deterioration progresses and becomes severe, the pipe deforms and often collapses along with t he
overlying roadway or improvements, which require costly emergency repairs and make the City
vulnerable to liability claims for damaged private property.
The project to replace the Bullock Lane Culvert, which conveys flows beneath Bullock Lane,
was originally started design in 2012. Due to funding constraints and permitting issues the
project was placed on hold until 2019 when design resumed.

VICINITY MAP
Project Description – Bullock Lane Culvert
The CMP storm drain culvert underneath Bullock Lane has completely rusted through and is
now allowing water to flow directly on top of native soil. This condition has allowed for native
material to erode away, creating large voids underneath the metal pipe. As these voids continue
to grow the structural integrity of the culvert and overlying roadway becomes compromised
further and could negatively impact the north/south railway tracks. In addition, a headwall that
supports the existing culvert at its outfall is failing and is in danger of collapse if not rep aired or
replaced. A complete failure of either the headwall or culvert would likely cause the roadway to
collapse and would negatively impact the railway (adding further costs to the City).
The goal of the Bullock Lane project is to replace the failing CMP storm drain with a High-
Density Polyethylene (HDPE) pipe of the same size. In addition, a concrete sack headwall that
currently exists in the Right-of-Way of Union Pacific Railroad (UPRR) company will be
replaced with a new concrete headwall located within the City’s right-of-way.
Previous Council or Advisory Body Action
Funding for the Bullock Lane project was allocated to the Storm Drains Annual Asset
Maintenance account in the 2019-21 Capital Improvement Plan. The supplemental budget that
was authorized by City Council June 2, 2020 allocates $250,000 in additional funds required for
project completion.

Policy Context
Per the October 2018 Purchasing Policy Update to the July 2015 Financial Management Manual,
Council approval is required for Public Projects that cost over $175,000.
Public Engagement
Public engagement was done during the initial identification of this project to be included in the
2019-21 Financial Plan.
COVID-19 Considerations
Due to the current economic impacts of COVID-19, the City reevaluated all Capital
Improvement Plan projects with the goal of adjusting Capital Expenditures in response to
projected revenue shortfalls, and aligning the adjusted CIP program with a focus on economic
recovery and fiscal responsibility. With these criteria in mind, this project was recommended to
continue since it addresses a critical and time dependent infrastructure need. Additionally, this
project supports economic recovery through contracts with local or regional companies that will
further retain employment and long-term viability of construction.
This project is critical to the safety of our community due to the risk of property loss with the
potential collapse of the existing CMP culvert and subsequent roadway failure that would result.
CONCURRENCE
The Administration and Public Works departments concur with the proposed recommendation
outlined in this document. In addition, concurrence by Union Pacific Railroads, Army Corp of
Engineers, Fish & Wildlife, and the California Regional Water Board has been shown through
the issuance of regulatory and encroachment permits.
ENVIRONMENTAL REVIEW
Staff recommends finding this project exempt from environmental review under Section 15302
Class 2 (Replacement or Reconstruction) of the California Environmental Quality Act (CEQA).
A Notice of Exemption will be filed through the Community Development Department upon
Council approval of the project.
All environmental mitigations have been outlined in the permits issued by the Army Corp.,
California Water Board, and Department of Fish and Wildlife. No additional environmental
review is required.
FISCAL IMPACT
Budgeted: Yes Budget Year: 2019-20 and 2020-21
Funding Identified: Yes

Fiscal Analysis:
There is currently a balance of $209,139.21 in the Storm Drain System Replacement Annual
Asset Maintenance Account (90742). This funding was recommended to proceed per the FY
20/21 Budget Supplement. Additional supplemental funding of $250,000 was appropriated as
part of the FY 20/21 Budget Supplement for Bullock Lane. The project is expected to cost
$377,000 to complete, which includes a 25% contingency, leaving $132,139 in the account. Staff
recommends a larger project contingency to address unforeseen conditions during construction
due to the impacts of the COVID-19 Pandemic.

Bullock Lane CMP Replacement, Specification No. 1000166
Remaining funding is anticipated to be utilized for an emergency replacement of failed CMP
storm drain at 405 N. Foothill, which is estimated to cost $75,000 to complete. Remaining funds
will be held for Trash Capture device installations.

ALTERNATIVES
Deny authorization to advertise. Council could choose to not authorize City staff to advertise the
Bullock Lane CMP Replacement Project. This is not recommended as further delay in the
replacement of the storm drain line and supporting headwall could result in the collapse of the
headwall and section of roadway supported by the line.
