TITLE:
HIGHWAY 78 WIDENING
DEPT. HD.
CITY ATTYV'O
CITY MGR. ^*—
RECOMMENDED ACTION:
Representatives from Carlsbad, Oceanside, County of San Diego, San x
Marcos and Escondido met with Congressman Packard on Thursday,
August 29, to discuss local participation in the widening of
Highway 78.
CALTRANS estimates the cost of widening to six lanes (no bridges)
will be $29.5 million.
Congressman Packard has been able to include a "demonstration"
project in the federal budget with $12 million funded over a
period of 3 years. He reports that demonstration projects are
funded only if there is local participation. This $12 million
was approved by a Congressional committee.
CALTRANS funding is slipping lower each year. The difference in
having federal and local participation would allow CALTRANS to
complete this road in five years rather than get on the waiting
list and be ten years. The CALTRANS representative at the
meeting indicated that CALTRANS could up its share to 35% since
the federal share turns out to be less than 50%.
SANDAG has made estimated cost allocations for local jurisdiction based
on 1980 census and Series 6 projected population figures. These
costs would be payable over a 3 year period. Gas tax funds could
be used. Our 1985-86 projected gas tax revenues are $568,000 +.
At this time the revenue is used for local road maintenance.
The cities of San Marcos and Vista have agreed to fund their share.
Carlsbad, Oceanside and Escondido requested more information.
Supervisor Eckert indicated he would seek county approval.
Congressman Packard requests an answer from each city by
September 15.

Attn: Yvonne Murchison
Dear Congressman Packard:
Last month you requested our assistance regarding the preparation of potential financing
plans for the widening of State Route 78 between 1-5 in Oceanside and 1-15 in Escondido.
CALTRANS has estimated that a project to widen SR78 to 6 lanes with some associated
bridge widening work would cost about $27 million. Federal funding through a special
demonstration project was assumed to provide $12 million with the state and local affected
jurisdictions sharing the remaining project costs.
SANDAG staff has evaluated a number of methods that could be used for allocating the
local project costs between the five cities and county adjoining the SR78 corridor. Those
methods primarily centered on using existing and future population adjacent to SR78 (4 and
8 mile wide corridors) and estimated travel on SR78 attributed to trips beginning or ending
in each jurisdiction.
The attached Table 1 includes the four factors that appear to reflect the closest corelation
between population and travel along SR78. The factors include 1980 Census population and
year 2000 Series 6 forecast population along a 4-mile corridor centered on SR78. Also
included are the estimated vehicles miles of travel on SR78 for both a 1980 base year and
2005 forecast year. Table 1 includes an average of these four factors for each jurisdiction
which was then used in Table 2 to determine potential local revenue allocations.
Table 2 is a potential cost and revenue allocation plan for widening SR78. The table in-
cludes the $27 million current project cost as well as a future (escalated) cost for January
1988. It would take CALTRANS about 2 years to prepare the SR78 project plans once they
get approval to start the project development work. The revenues assumed in Table 2
reflect a fixed $12 million federal share and splitting the remaining project costs 50% to
the state and 50% to local jurisdictions. There are no state revenues presently programmed
for the project in the 1985 State TIP. The local jurisdiction revenues are based on the
average percentages shown on Table 1. Any cost-sharing agreements should also consider
how potential cost increases or overruns might be funded.
Please let us know if there is any other information you might want.
Sincerely,
BELL TUOMI

The 16.5 mile segment of Route 78 connects Interstate Routes
5 and 15 in northern San Diego County. This is one of the
fastest growing areas in California. Regional growth fore-
casts show an 807. growth in population by the year 2000 for
the cities along this segment of Route 78 as shown In Table 1.

Traffic has increased 25-307. since 1981 causing some congestion
on the portions from 1-5 to Melrose and San Marcos Blvd. to
1-15. Current Route 78 traffic volumes vary from about 47,000-
78,000 average daily traffic (1984 ADT). Route 78 currently
operates at Level-of-Service (LOS) "C" to "E" with average peak
hour operating speeds in the 20-50 mph range. The three year
accident data (1980-82) show that Route 78 fatal, Injury, and
total accidents are at or below statewide averages for similar
facilities.
Traffic forecasts for the year 2005 show a substantial increase
in Route 78 traffic which would vary between Oceanside and
Escondido in the 85,000 - 112,000 ADT range. A six-lane free-
way could accommodate these traffic levels at a LOS "D"
condition with average peak-hour speeds in the 30-45 tnph^range.
The existing four-lane freeway would operate at a LOS 'Fu
condition, congestion, and 15-20 mph speeds for many hours of
the day.
The proposed project would add two additional traffic lanes mak-
ing N Route 78 a full six-lane freeway (three continuous in each
direction). '

Note :
Level-of-Service Definitions
LOS "C" - Stable flow, drivers restricted in freedom to
select own speed, change lanes or pass -
speeds 45 to 55 miles per hour.
LOS "D" - Unstable flow with tolerable operating speeds
being maintained. Drivers have little freedom
to maneuver and comfort and convenience low.
Average speed 30 to 45 miles per hour.
LOS "E" - Flow is unstable and there may be stoppage.
Average speed 20 to 30 miles per hour.
LOS "F" - Forced flow operation. Speeds are reduced
substantially and stoppages occur for long
periods of time because of congestion. In the
extreme speed drops to zero. Average speed
0-20 miles per hour.
