AND MEMBERS
ROSEMEAD REDEVELOPMENT AGENCY
FROM: FRANK G. TRIPEPI, EXECUTIVE DIRECTOR
DATE: OCTOBER 7, 1997
RE: ENGINEERING PROPOSAL - STORM DRAIN IMPROVEMENTS IN
KELBURN AND DELTA AVENUES
Attached for your consideration is an engineering proposal from Willdan Associates for
storm drain improvements in Kelburn Avenue and Delta Avenue. The Kelburn Avenue
storm drain project includes installation of storm drain mainline adjacent to Garvey Park
in Kelburn Avenue from Emerson Place to Dorothy Avenue and in Dorothy Avenue from
Kelburn Avenue to approximately 600 feet west. The Delta Avenue storm drain project
includes installation of mainline storm drain in Delta Avenue extending from Earle Avenue
to Dorothy Avenue.
The proposed storm drain systems will collect surface water runoff tributary to each
corridor. The new mainlines in Kelburn and Delta Avenues will join the existing drains in
Emerson Place and Earle Avenue, respectively. The drainage improvements will include
catch basins along the alignment to collect storm runoff.
The current estimated construction cost for the total project is $363,000; $213,000 for the
Kelburn Avenue storm drain and $150,000 for the Delta Avenue storm drain system. The
Kelburn and Delta storm drain projects are currently programmed in the Rosemead
Redevelopment Agency FY 1997-98 budget. It is proposed that both storm drain projects
be constructed under one contract; the estimated contract period is 25-working days.

Subject: Proposal for Professional Engineering Design, Design
and Construction Surveying, Utility Coordination, Contract
Administration, and Construction Observation for Storm Drain
Improvements in Kelburn and Delta Avenues
Dear Mr. Tripepi:
As requested, we are pleased to be given the opportunity to submit this proposal for the
above-referenced services.
The Kelburn Avenue storm drain includes installation of storm drain mainline in Kelburn
Avenue from Emerson Place to Dorothy Avenue and in Dorothy Avenue from Kelburn
Avenue to approximately 600 feet west. The proposed storm drain mainline in Delta
Avenue will extend from Dorothy Avenue to Earle Avenue.
Catch basins and connector pipes will be located along the storm drain alignments to
collect surface water runoff generated on each corridor. The proposed storm drain
systems in Kelburn and Delta Avenues will join the existing drains in Emerson Place and
Earle Avenue, respectively.
We propose to provide the following basic services:
HYDROLOGY STUDY
1. Provide a visual survey to establish hydrologic contributory areas.
2. Perform hydrologic calculations necessary to determine flow rates and collection
points.
3. Submit hydrology study to Los Angeles County Department of Public Works for
approval.

DESIGN SURVEY
1. Perform research at Los Angeles County and the City of Rosemead for survey
information.
2. Establish centerline for Kelburn, Dorothy, and Delta Avenues throughout the limits
of project.
3. Provide elevational data to establish accurate profiles and proposed catch basin
elevations.
4. Provide topographic feature locations for a complete and accurate storm drain plan
in the street area between curbs.
PRELIMINARY DESIGN PHASE
1. Confer with Agency staff to review, in more detail, the requirements for the project.
Review available information and data assembled by the Agency staff.
2. Research readily available existing underground utilities which may be affected by
the storm drain improvement.
3. Review compiled data.
4. Develop base drawings.
a. Rot existing survey data.
b. Identify and plot apparent substructures.
c. Conduct field verification.
5. Perform hydraulic calculations necessary to fully design the storm drain
improvements.
6. Develop profiles for the storm drain improvements.
7. Develop complete plan and profile sheets for the storm drain line, connections,
catch basins, manholes, substructures, and utilities. The design will follow Los
Angeles County Department of Public Works standards and requirements for a
Miscellaneous Transfer Drain (MTD).
8. Provide profiles for catch basin connectors and other inlets.

9. Develop preliminary cost estimates.
10. Submit preliminary design plans to all affected agencies and utility companies for
review, including storm drain plans to Los Angeles County Department of Public
Works..
FINAL DESIGN PHASE
1. Based on the Agency, County's, and utility companies' comments and
requirements, revise the plans.
2. Submit revised plans to the County for final review and comment.
3. Prepare final plans and coordinate with Agency personnel, County, and utility
companies, as necessary, at various times during the design phase.
4. Obtain final approval from the County, including the necessary permits for
construction.
5. Prepare specifications and contract documents to conform to applicable
requirements of Rosemead Redevelopment Agency.
UTILITY COORDINATION
1. Submit copies of the plans to affected utilities and agencies.
2. Determine any utility conflicts with the storm drain based on utility companies'
comments and plans.
3. Coordinate potholing investigations to verify depths of potentially conflicting utilities.
4. Coordinate relocations of utility lines necessary for storm drain construction.
5. Coordinate with utility companies to provide for any proposed utility improvements
prior to new construction.
6. Attend and coordinate the preconstruction conference.
CONSTRUCTION SURVEY
1. Set grade stakes at a uniform offset for mainline.

The current estimated construction cost for the total project is $363,000; $213,000 for the
Kelburn Avenue storm drain and $150,000 for the Delta Avenue storm drain system. The
design fee is based on the curve fee schedule from the American Society of Civil
Engineers. The total fee, excluding hydrology study and utility coordination, is in
conformance with that portion of the City's agreement with Willdan Associates which
pertains to design engineering services. The construction contract period is estimated to
