SUBJECT: Consider Design for the North Leg of the Intersection of
Spring Road and New Los. Angeles Avenue [Portion of
Project 80261
OVERVIEW
The purpose of this report is to seek conceptual approval of the
proposed design for a double left -turn lane for south -to -east
left -turn traffic at the intersection of Spring Road and New Los
Angeles Avenue. If approved, these improvements will become a part
of the Spring Road Widening project.

A. Background
The Budget includes Project 8026, a project to widen Spring
Road from New Los Angeles Avenue northerly to the railroad
crossing. This project is currently under design. It is
anticipated that right -of -way acquisition for the project will
start in about three to four months.
B. Approved Design Standard
The design standard approved for this segment of Spring Road
is generally depicted as follows:
10' *6' 12'
* Bike Lane
12' 14' 12'
74'
94'
12' *6' 10'

The present dimensions of the street are as follows:
• Curb -to -curb: sixty -four feet (641)
• Right -of -Way: eighty feet (801).
C. Flinn Avenue Realignment [Project 80371
Work is also proceeding on the design for the realignment of
Flinn Avenue to intersect Spring Road at Second Street. The
scope of that project will include:
• the construction of the new "realigned" street;
• construction of a traffic signal at the new four -way
intersection; and
• construction of street widening along the east side of
Spring Road between the new Flinn Avenue and the Railroad
tracts:
• This will complete the construction of the street
widening, curb and gutter along the Spring Road frontage
of the future Police Station site.
• Construction of sidewalk in this area will be deferred
until the construction of the Police facility or the
development of the area north of the proposed police
facility, whichever comes first.
D. Project Objectives
As depicted by the above diagram, the objectives of the
project are to provide:
• four 12' wide travel lanes
• two 6' wide Bike Lanes
• one 14' wide landscaped median; and
• a 10' wide parkway /sidewalk on each side of the street.
E. Project Scope
The scope of the subject project, therefore, requires:
• acquisition of additional street right -of -way along the east
side of the street;
• construction of street widening along the east side of the
street south of the new Flinn Avenue; and
• construction of the center landscaped median.
The project will not require the relocation or reconstruction
of any private improvements. It will not require the deletion
of any parking spaces. It will, however, reduce the width of
the existing landscaped areas along the east side of the
street.

F. Double Left -Turn Lane
There is a relatively high volume of traffic for the south -to-
east left turn movement. The Level of Service (LOS) would be
improved if a double left -turn lane were to be provided for
this turning movement. Attached as Exhibit 1 is a diagram
showing the proposed design for this element of the project.
This design concept provides for two eleven feet (111) wide
left -turn lanes, plus a two feet (21) wide median. The street
right -of -way required for these improvements is ten feet (101)
wider than the amount of additional right -of -way required for
a project with only one left -turn lane. This additional right -
of -way would be taken from the existing landscaped area east
of the current sidewalk along the frontage of the McDonald's
restaurant.
G. Landscaping
In that the street in the vicinity of the McDonald's
restaurant is slightly wider than the width of the street to
the north, a project with only one left -turn lane would
require only about two feet (21) of additional right -of -way to
construct. This would have a minimal impact on the existing
fifteen feet (151) wide landscaped area located east of the
existing right -of -way line. The additional ten feet (101)
required for the second left turn lane would reduce the
landscaped area considerably. However, with the placement of
the sidewalk adjacent to the curb, it is anticipated that the
landscaped area to remain would be approximately eight feet
(8') wide.
H. Fiscal Impact
The estimated total cost of the project is as follows:
Design
Right -of -Way
Construction
Contengency (10 %)
Inspection
Total
64,750
200,000
700,000
70,000
50,000
1,084,750
Note: The above cost estimate does not include the cost of Spring Road
Widening north of Flinn Avenue.
