SUBJECT: PARAMOUNT BOULEVARD AT FIRESTONE BOULEVARD
INTERSECTION IMPROVEMENT PROJECT – EXECUTE AGREEMENT
AMENDMENT
RECOMMENDATION
1. That the City Council authorize the Mayor to execute an amendment to the
agreement with APA Engineering, Inc. for professional engineering services
related to the Paramount Boulevard at Firestone Boulevard Intersection
Improvement Project; and
2. Approve a change order to the City’s contract with APA Engineering, Inc. in the
amount of $63,143 to revise the design for the project.
BACKGROUND
The Paramount Boulevard at Firestone Boulevard intersection involves two major
arterial routes within the City of Downey and two facilities of regional significance. At
this intersection, Paramount Boulevard has an existing Average Daily Traffic Volume
(ADT) of 30,000 vehicles per day (VPD), while Firestone Boulevard has an existing ADT
of about 43,000 VPD. In addition, both Paramount Boulevard and Firestone Boulevard
are designated truck routes, and hence, have a significant volume of truck traffic on a
daily basis. Paramount Boulevard and Firestone Boulevard have truck volumes of
2,900 and 3,100 VPD, respectively. This intersection has an ADT of 52,000 VPD and
operates at level-of-service (LOS) “D” and “E” during AM and PM peak hours,
respectively, on a typical weekday.
By 2035, due to regional background traffic volume growth, as well as, future estimated
traffic generated by proposed development within the region, it is anticipated that this
intersection will experience an estimated 35% increase in traffic volume to 70,000 VPD.
Consequently, an increase in congestion, resulting in the deterioration of the LOS to “F”
at this intersection during AM and PM peak hours, is expected. In addition, the existing
curb returns do not have a large enough radius to safely and effectively accommodate
right-turn movements by large trucks, forcing them to cross multiple lanes when
completing right turns.
In order to accommodate this projected traffic volume growth, sustain the LOS at this
intersection to acceptable levels of “D” and “E” during AM and PM peak hours,
respectfully, and allow for safe, efficient truck movements over the next several
decades, the City intends to initiate a project to improve this intersection. The project

will involve the construction of double left-turn pockets in each direction, a right-turn
pocket in the eastbound direction and the reconstruction of all four curb returns to
provide 50-foot radii. The acquisition of up to 12,000 square feet of right-of-way from
the four contiguous properties will be required at each of the four corners of the
intersection to allow for the construction of the larger curb returns and the right-turn
pocket at the southwest corner.
The right-of-way necessary to construct the right-turn pocket on the southwest corner of
the intersection for right turns from eastbound Firestone Boulevard to southbound
Paramount Boulevard will require the demolition of an existing structure in addition to
the acquisition of property. The project will also include the modification of the traffic
signal at the intersection as well as all incidental utility relocations and striping and
signage modifications.
An aerial view of the Paramount Boulevard at Firestone Boulevard intersection is shown
on the attached Project Location Map.
DISCUSSION
Originally, the proposed intersection design included the addition of the exclusive east
bound right-turn lane as well as the reconstruction of the curb returns at each of the four
corners at the intersection. APA Engineering was retained to provide the intersection
design to incorporate these improvements for a fee of $137,453. The original design
was completed in April 2011. The original design concept, however, did not include the
double left-turn lanes in each of the four directions at the intersection given that the
traffic volume projections available from the City’s General Plan Circulation Element at
the time the original concept was being developed did not show a need for the double
left-turn lanes. Therefore, the design must be revised substantially in order to include
the double left-turn lanes.
Year 2035 traffic volume projections recently made available for the intersection from
the I-710 Major Corridor Study Environmental Impact Report (EIR), however, show a
need for double left-turn lanes in each of the four directions at the intersection. In
addition, the traffic study completed recently for the Downtown Specific Plan identifies a
need for double left-turn lanes in the southbound direction in order to sustain an
acceptable intersection LOS for year 2035 conditions.
For reasons of economies of scale and minimal impact on the public, to the extent
possible, staff concluded that the inclusion of the double left-turn lanes as part of this
project would be beneficial. Therefore, it is recommended that an amendment to the
agreement (see attached) with and a change order to the contract with APA
Engineering be approved in order to modify the intersection design to include the double
left turn lanes.

PROJECT UNDERSTANDING AND SCOPE OF WORK
EXHIBIT A
PROJECT UNDERSTANDING AND OVERVIEW
The City of Downey is seeking qualified firms to prepare construction plans and bid documents for
improving the intersection of Paramount and Firestone Boulevard in the City of Downey.
The improvements proposed under this project will involve the construction of a right turn pocket in
the eastbound direction on Firestone Blvd. at its intersection with Paramount Blvd. and the
reconstruction of all four curb returns at the intersection to provide 50-foot turn radii. The
construction of the eastbound right turn pocket will allow for the striping of a third eastbound
through lane on Firestone Blvd. to help alleviate a bottleneck on this facility. Right-of-Way
acquisition will be required at each of the four corners with the majority of take at the southwest
corner to allow for the re-construction of the curb return and right-turn pocket. The project will also
include construction of curbs, gutters, ADA accessible ramps, driveways, sidewalks, utility
relocations, and incidental traffic signal, striping, pavement marking and signage modifications.
The existing intersection pavement will be rehabilitated to improve ride quality and extend its useful
life by a minimum of fifteen (15) years. The work will include reconstruction of failed pavement
areas, cold milling the existing A.C. pavement, construction of A.C. base courses, resurfacing with
rubberized asphalt concrete pavement, and the adjustment of manholes and utility valve covers to
grade. All work will conform to Greenbook, Caltrans, and current City of Downey standards.
The funding for this project is through Los Angeles County Metropolitan Transportation Authority
(METRO) Proposition “C” funds, federal DEMO funds, and City funds. Project Development and
implementation will be in accordance with the METRO Proposition “C” MOU and the Caltrans Local
Procedure Manual.
Summary of Improvements:
Widen AC pavement to allow for a new right turn pocket and larger turning radii
Construct new curb & gutter and sidewalk
Relocate/Adjust utilities, as necessary
Construct retaining wall. as necessary
Construct new ADA Access Ramp
Modify Traffic Signals, striping, signing, and lighting as necessary
Modify landscaping & Irrigation as necessary
Relocate private facilities and commercial signs as necessary
Relocated and/or modify storm drain facilities as necessary
Issues to be considered during design development
APA Engineering staff visited the project site, conducted a job walk with City staff, and collected a
great deal of field information which resulted in identification of the following issues for
consideration during design development:
1. Proposed right turn pocket will require right-of-way take including removal of portion of block
wall at the Paint and Body Shop, existing building (restaurant), traffic signal, ADA ramps,
utilities, and existing storm drain catch basin
2. Right-of-way acquisition will be handled by the City. Based on the assessor’s map obtained
from County of Los Angeles, it appears that five (5) parcels will be impacted
3. Video detection system has been installed on signals so traffic loops should be removed.

City of Downey
PROJECT UNDERSTANDING AND SCOPE OF WORK
4. Utilities will need to be relocated: SCE and telephone vault at right turn lane (SW corner),
Communications vault and water meter at NE corner. There are traffic signal controllers
located at SE corner and they may need to be relocated for ADA access.
5. Existing Fire Hydrant at SW corner to be relocated to a more suitable location.
6. There are six existing catch basins in the intersection area. The one within the proposed right
turn lane on Firestone Blvd. and the two on Paramount south of Firestone will need to be
relocated. The other two north of Firestone along Paramount will have the local depressions
modified to a Type E so that they are in line with the gutter.
7. Pavement to be rehabilitated approximately 300 feet each side of the intersection on all four
legs of the intersection.
8. About 8 to 10 borings samples will be needed to generated 5 to 6 “R” Values for a pavement
section at intersection and at the right turn lane.
9. The intersection will be cold milled, raised with AC as required and then topped with 2” ARHM.
Based on a field review, no deflection testing will be needed.
10. The business driveways will need to be improved to comply with ADA standards. The driveway
lip can be increased to 1.5 inch to lower the slope of the driveway.
11. There are four bus stops at the intersection; the pavement at the bus stops (bus pads) will be
revised to full depth AC. The bus stops currently do not have shelters and do not provide
adequate ADA access behind the benches. Explore possibilities of installing bus stop shelters
approved by MTA
12. The entire frontage of the affected businesses can be improved in order to make the project a
better sell to the businesses.
13. The project is being funded with federal and MTA funds.
14. Raise the flow line on SW at proposed right turn lane. Existing cross slope to steep.
15. Remove and restore landscaping and irrigation on southeast, northeast, and northwest corner
of the intersection
16. Match curb & gutter at the point where existing curb & gutter ends on SW corner
17. Allow three through lanes on Firestone Blvd. eastbound. Drop a lane, if necessary, after it
clears the intersection due to lack of right of way.
18. Utilities relocation and adjustments. Some utilities may require long lead time to be relocated.
Therefore, immediate notification of the owners is essential.
19. Drainage Issues-currently flow line on eastbound Firestone near the proposed widening does
not function properly and must be regraded to flow easterly towards the nearby catch basin.
20. Crosswalks and ADA access Ramps will have to be reconfigured to match the proposed
intersection configuration
21. Signal Relocation/new pole and mast arm will be required.
22. Driveways and Approaches must be brought to current ADA standard
23. Intersection Grid Grades must be developed to ensure good riding surface and good drainage
24. Sidewalk Removal at intersection must be done at even joints for the entire curb return.
25. Pavement overlay limits to be at logical and even station lined up on both sides of the street
26. Curb height to be consistent as much as possible
27. Grading behind the proposed back of walk must be done in a delicate manner to minimize the
need for retaining wall and impact on adjacent properties.
28. Relocate Fire Hydrants as requested
29. Remove and restore signs and lighting on private property/Businesses
30. Possible use of colored pavers for cross walk delineation
31. Develop traffic control plan for construction staging which minimizes impact on motorist and on
adjacent businesses.

evaluate existing conditions of the pavement, curb and gutter, sidewalk, driveway approaches, etc.
The field walk will also include a review of any damaged, raised, or sunken curb and gutter,
sidewalk, and other concrete improvements within the public right of way that are in need of
repairs. The following criteria shall be used in the determination of these repair locations:
1) Curb and Gutter:
Vertical or horizontal displacement of 1” or greater
Areas which create 1” or more of ponding water
2) Sidewalk and driveway approaches within pedestrian area:
Vertical displacement of ¾” or greater.
Issues such as coordination with any on-going adjacent projects, adjacent property owners affected
by the project and traffic control will be also addressed during these field walks.
Deliverables
- Meeting Attendance Rosters and Minutes
2.4 Utility Investigation and Coordination
APA Engineering will prepare an initial request for utility information such as atlas sheets, mapping,
or as-built plans. The collected utility information will be superimposed on the project base map.
APA Engineering will submit 90% and Final plans to utility companies for their review, and will
request utility information, verifications, and relocations plans form the utility company, if applicable.
Plans will only be distributed to those utility companies with facilities within the
project area, as identified from the initial request for information.
This work will be performed based on the guidelines specified in the APA’s “Utility Coordination
Procedures”. APA Engineering will contact water, sewer, storm water, electric, telephone, gas,
cable and all other utilities providing service within the project area. We will notify each utility
company (by certified mail) of the City’s proposed plans, proposed schedule and obtain as-built

City of Downey
PROJECT UNDERSTANDING AND SCOPE OF WORK
drawings of the existing utilities using the form provided by the City. We will provide 50% level of
completion plans and final plans to the various utilities and identify any necessary utility relocation
for the construction of the proposed improvements. We may request potholing to locate vertically
the existing underground utilities. Potholing will be paid for on an as-needed basis by the City or
effected utility owner.
The City will be responsible for the development of all utility relocation agreements and/or utility
easement acquisition documents, for negotiations with the utility companies regarding cost
responsibility, and for processing the utility relocation agreements for signature approval by the
utility company and the City. The APA Engineering will be responsible for coordinating technical
design issues with the utility company, for reviewing utility relocation agreements to provide input
and comments from a technical design standpoint, for preparing legal descriptions and exhibits for
new revised utility easements, if required (by separate task), and for assisting in schedule
management between the City and utility company as it relates to the overall design schedule.
APA Engineering will review utility relocation plans, if applicable, received from the utility
companies for conformance to project needs.
Dry utility companies will perform design work with their own forces in preparing final utility
relocation plans, if required. Utility companies will be responsible for preparation of legal
descriptions and exhibits, and permit procurements for and interim utility relocations requiring
temporary easements.
Deliverables
- Distribution of one 11” x 17” plan set at the 90% and final completion levels to all utility
companies involved. APA will submit full size plans to those utility companies whose lines are
impacted and need detailed work to either upgrade or relocate their line.
2.5 Prepare Preliminary Environmental Study forms for Caltrans review and approval
The City will prepare the environmental documents (PES Form and CEQA/NEPA Form) in the
interest of getting this project in the Caltrans review pipeline for possibility of Economic Stimulus
funds. The City will, however, have APA Engineering complete any additional environmental
studies which may be required following Caltrans review as an extra item.
2.6 Geotechnical Investigation and Pavement Design Recommendation
APA Engineering will perform a geotechnical investigation to determine the existing pavement
structure thickness within the project area and current “R” value. The investigation will be limited to
obtaining pavement cores and providing pavement thickness design to be used for widening of
Firestone Blvd. eastbound and all four corners of the intersection and to confirm adequacy of the
existing pavement section for the intersection.
APA Engineering proposes to take 8 to 10 boring samples to generate 4 to 6 “R” values for
pavement analysis and design of three (3) alternative pavement structure sections. The design T.I.
will be provided by the City.
APA Team will prepare a report summarizing the visual site descriptions, verification of the existing
pavement sections and a recommended pavement section, if full replacement is needed. This will
be based on traffic indices provided by the City of Downey. Design period will be for a period of
fifteen (15) years.

PROJECT UNDERSTANDING AND SCOPE OF WORK
2.7 Surveying
APA will provide the City with a precise and detailed schematic base map at 1:20 scale with 1 foot
contours. The base map will identify all existing street improvements, edge condition, driveways,
property lines, sidewalks, existing right-of-way, drainage structures, fire hydrants, utility facilities,
trees, signs, street lights, striping, traffic signal poles, private and commercial features, walls, etc.,
and other appurtenant improvements in the project area.
As the project may require detail design to match and join existing features, full topographic field
survey and cross sections will be required. Topographic survey will extend 400 ft. beyond all
BCR/ECR’s on adjacent cross streets.
Surveying will include legal descriptions for right-of-way acquisition, establishment of centerline
stationing, location of topographic features within the traveled roadway, street cross sections,
centerline profile and drainage profiles, typical cross sections at transitions and all locations where
geometric characteristics of the street vary.
The basis of horizontal control will be North American Datum of 1983 (NAD 83) as published by the
county unless otherwise requested. The basis of vertical control will be National Geodetic Vertical
Datum of 1929 (NGVD 29), based on established City of Downey benchmarks
2.8 Community Outreach-Optional and AS-Needed
