IV. RECOMMENDED HIGHWAY SYSTEM
This chapter Presents highway system recommendations for the City of Encinitas. The,
rCCUzZlmeflda?iOflS and their supporting data are intended to provide a basis for defining tf
circulation element of the General Plan.
LAND USE PLAN
As part of the overall General Plan study, a preferred land use plan was developed. Th
previous chapter documented three alternatives that were being studied during this process anc
a preferred land use plan evolved from that analysis.
Table IV-l summarizes the land use and trip generation for the preferred plan. Detailed
listings by subarea and by zone can be found in Appendix B. The total ADT trip generation of
71 1,900 compares with 764,400 for alternative LUl, 737,500 for LU2 and 766,900 for LU3.
ROADWAY FACILITY DESIGNATIONS
e* To define the future roadway system in the General Plan circulation element, a hierarchy
The individual facility types differentiate the size, function and of facility types is used.
capacity of the roadway links in each facility type designation.
Table IV-2 summarizes the facility types used in the arterial highway classification system.
There are four basic categories in the hierarchy, ranging from "Prime Arterial" as the highest
capacity facility, through "Major" and "Collector," to "Local" as the lowest capacity facility. A
designated local differs only from a non-designated local (Le. not in the circulation element) in
that it provides circulation continuity or an important accessibility function. For example,
closing a designated local for any reson would require a General Plan Ammendment whereas
closing a non-designated arterial would not. No improvements are implied by this designation.
As noted in this table, the augmented categories refer to capacity augmentation of the
basic facility type being referred to. Such augmentation can range from simply adding lanes at
specific intersections, to adding or expanding a median and/or other midblock measures to
improve traffic flow and reduce side friction. The lowest augmented category defined here,
namely the augmented local, may in its simplest form be just a two-lane local street with
special intersection treatments such as signalization and/or added lanes. A more highly

RECOMMENDED HIGHWAY SYSTEM
The highway network alternatives in the previous chapter focused on several major
with respect to the Encinitas circulation system. As a result of those analyses, s(
conclusions can be made.
1. There is a need to significantly augment the current east-west capacity. The
important facilities in this regard are La Costa (expansion to four lanes), Manct
(expansion to six lanes) and Encinitas (expansion to six lanes).
2. The necessary additional east-west capacity augmentation can be accommplished
two-iane connection of Leucadia to Olivenhain Road and additional circulation elements s
of Leucadia which connect El Camino to Encinitas.
3. A -off exists between extending Leucadia as a two-lane augmented local as I
above, and expanding Saata Fe Drive to a collector level facility (versus an augmented 1
while not making the Leucadia connection.
4. Of major importance is increasing north-south capacity

Costa, thereby providing a parallel circulation facility.

thcn major improvements to the Santa Fe/i-S interchange will also be required.
The recommended circulation plan is illustrated in Figure IV-I. Corresponding ADT t
volumes in the form of a flow diagram similar to those presented in the previous chapte
be seen in Figure IV-2. In Figure IV-3 the corresponding volume/capacity ratios for Lev
Service "D" are presented.
In general, it, can be seen that the circulation system has adequate capacity for
proposed land use plan. While some short sections show volume capacities greater than
these are generally problems that can be alleviated by suitable intersection treatments ra
than by expanding the complete facility in question.
The recommended phi includes Leucadia as an augmented local extending through

An important part of the recommended plan is the increase in capacity on Manch

Alternative circulation system
An alternative circulation system that was considered in this analysis involves the trac
off between the Leucadia extension and the improvement of Santa Fe to a major arterial. 1
alternative would delete the two-lane extension of Leucadia east of Quail Gardens, and instc
davslop Santa Fe as a four-lane arterial.
Figure IV-4 shows this alternative pian, and Figures IV-5 and IV-6 show the ADT volurr

In Table IV-4 a set of ICU values for major intersections are presented for both plai
