NIEMORANDUM
September 27, 1973
TO : Acting City Manager
FROM : Acting City Engineer
SUBJECT: Proposed City Council Policy - traffic signalization
Background
Several Carlsbad tentative maps within the last 18 months or so have been conditioned that the applicant participate in the installation of fully actuated traffic control signals within or adjacent to the proposed subdivisions. Each tentative map was reviewed on an individual basis, with the result that the extent of developer participation varied. Factors such as internal and external traffic circulation, master circulation plan, trip predictions generated by the proposed subdivision, traffic signal warrants, traffic safety analysis, geographical location of the proposed subdivision and other factors were reviewed by staff, Planning Commission and City Council i.n order to determine reasonable requirements.
Virtually every developer or his representative has challenged any requirement for participation in traffic signal installation. The
notable exception was the Papagayo development, where the developer volunteered to construct a signalized intersection at Jefferson and Tamarack as a condition of tentative map approval.
Exhibit "A" shows some typical examples of subdivisions that have been
required to participate in traffic signal installation.
Case I - Conditions:
a. Entire limits of subdivision adjacent to an existing (or proposed)
b. New proposed street will create intersection.
c. Projected traffic entering intersection will warrant a traffic signal
a. Construct traffic signal as part of subdivision improvements,
major arterial street.
Requirements of developer:
or b. Provide suitable guarantee (future agreement secured by cash, bond or instrument of credit).
In Case I, the developer may be reimbursed for a portion of his costs
(50% maximum) as other developments occur on the other "corners" of the intersection.
Case I1 is identical to Case I, except the developer may be able to be
reimbursed for 75% of his initial costs as other development occurs.
Case 111 is a schematic attempt to describe the La Costa subdivisions which,
although somewhat removed from a particular intersection, do generate the
traffic that creates the need for the traffic signal.
MEMORANDUM
Acting City Manager Traffic Signalization Page 2
In June 1973, the City Council in reviewing the tentative map for La Costa
Vale Units 2 and 3 (CT 72-20) stated specifically that La Costa Land Co.
was to pay for the traffic signal at El Camino Real and La Costa Avenue.
Subsequent correspondence and discussions between the City and La Costa Land Company led to Agenda Bill 2105, which was presented to City Council
on August 7, 1973.
The substance of the agenda bill was that:
1. The developer still objected to the requirement that he install the
2. The County would enter into an agreement with the City to construct the
3. La Costa Land Co. would be willing to loan the City the required $22,000
signal.
signal if the City could fund 50% of the $44,000 estimated cost.
at 7% interest for 5 years.
It was staff's recommendation that, should La Costa Land Co. deposit $22,000, the City should enter into a cooperative agreement with the County to construc
the signal.
After considerable discussion, no action was taken on AB2105. Staff was
asked to study "temporary means of relieving the traffic situation at El Camino Real and La Costa Avenue." Staff was also directed to prepare a proposed policy for installation of signals in the City of Carlsbad.
Progress to Date
Our Engineering Division contacted the County traffic engineering staff and recommended a temporary installation of four-way stop controls at the intersection. The San Diego County Traffic Advisory Committee approved
the four-way stop installation on August 28, 1973 and the four-way stop
was installed by County crews on September 19, 1973.
Traffic Signal Policy Research
In developing policies on traffic signal installation, two questions immediately come to mind:
1. What standards or criteria should be used to determine whether a traffic
2. When itis determined that traffic signal is or will be required, how signal is or will be required at a particular intersection?
will the construction of the signal be finGced?
Other questions such as how a signal should be installed and what components should be used are simply technical design aspects and not a part of this discussion.

Traffic Siffnal Warrants
Much staff time was spent collecting data from other agencies on traffic
signal "warrants". While two agencies (City of San Diego and Orange County)
had significantly higher minimum requirements before an intersection might
justify or "warrant" a traffic signal, most jurisdictions have adopted
minimum warrants for the installation of traffic signal systems based on
the nationally (and statewide) accepted warrants as depicted in the manual
on Uniform Traffic Control Devices for Streets and Highways.
Exhibit "B" is a compilation sheet of the warrants. This traffic signal warrant sheet will be recommended for addition to City Council Policy Statement No. 9 (Traffic Safety Policies and Warrants) at a future Council meeting.
One thing was very clear in our research. Traffic signals will be required where four lane roads intersect other four lane roads (based on minimum
vehicular volumes).
Traffic Siqnal Construction Financinq
Before embarking on developing a policy, it is not an unwise thing to check
and see what everybody else is doing. With more chronological time available,
we may have been able to contact cities our size who have successfully come
to grips with the problem. No such luck. Most cities seem to be doing
just like we have been doing. That is, they have been requiring develop-
ments that generate traffic (or will generate traffic when fully occupied)
that warrants signalization to construct and/or finance those signals. The
City of San Diego evidently finances most of their signals through gas taxes or capital improvement projects. Most all cities finance some signal
construction through TOPICS, gas tax, City-County thoroughfare funds, revenue sharing, etc.
Several areas of potential City financing of signal installation were studied,
--General Obligation Bonds or Redevelopment Agency funding might be feasible 10 years down the road, but those possibilities are slim unless traffic
circulation is so bad then that G.O. Bonds or Redevelopment is the "only
way out".
--Revenue sharing funds are also a possibility. In fact, $30,000 has already
been authorized for Pi0 Pic0 at Tamarack traffic signal. Financing future
traffic signals from this source would be an unusual commitment, what with
other areas of City services in need of funds.
potential source. However, historically, General Funds have not been sufficiently plentiful to use for this purpose. Gas Tax funds, by them- selves, just won't stretch that far.
--Capital Improvement Program - General Funds plus Gas Tax Funds are a
MEMO-RANDUM

Exhibit "C" is a rough estimate of projects that should be done in the next
10 years (rough cost $2.8 million). The anticipated gas tax revenues over
the same period (assuming that none of it gets funneled into mass transit or other needs) is $1.72 million. In other words, the needs exceed the means by well over $1.0 million.
At an average cost of $30,000 to $35,000 per signal, it is my estimate that during the next 10 years, approximately 20 signals or $700,000 will be required.
Because of the lack of availability of City funding for future traffic
signal installation in newly developed areas, I recommend for consideration
Exhibit "D", a proposed Council policy statement regarding Developer Respon-
sibility for Traffic Signals. I am also attaching Exhibit ''E", Board of
Supervisors Policy for information.
While I am recommending Exhibit "D" as a proposed Council policy whereby
the developer would pay cash into a trust fund prior to recording his
subdivision map, future consideration should be given to provide the necessar)
legislation (state and local level) to allow for the collection of a "Traffic Signal Benefit" fee at the time of building permit issuance. This fee policy (see Exhibit "F") would be similar to local drainage area fees or "Bridge Benefit" area fees which now can be collected either at
the subdivision map stage or at the building permit stage.
It is estimated that such a fee would be approximately $75-80 per dwelling
unit. Some of the advantages of such a fee are:
1.
2.
3.
4.
5.
6.
7.
The developer would not have to put up all the cash at such an early phase of development. Building permits (or occupancy) more closely correlates with actual traffic generation and hence need for signalization. Such a fee would be most easily administered by the City, therefore less overhead and more efficient use of monies.
Fee would be easily adjustable to compensate for future signal costs. City could collect fees from many subdivisions previously approved as building permits are issued, thereby spreading cost over those who will
benefit most.
This is more equitable on the average, particularly for small develop-
ments which may, because of geography, have the requirements for more
than one signal.
This would not require the first developer in an area to finance an entire signal while later developers don't pay because signal is already
installed.

PI cLmb e r I
TO establish a policy for the participation by private developers,
individuals, organizations or other public jurisdictions for the
installation of traffic signals.
Background
The installation of traffic signals in many instances involves inter-
sections for which one or more of the approaches to the intersection
are under the jurisdiction of another governmental entity.
fn other instances in the review of a proposed Tentative Map it is
apparent that a proposed development could contribute substantially
to the need for a signalized intersection st a specific location.
There are also occasions where an individual, developer,. or organiza-
tion indicate a willingness to pro;lide additional. contriburions to
accelerate the installation of a traffic signal at a location which
meets traffic signal warrants but is not high enough on the Signal
Priority List to justify the budgeticg of County funds for the project.
To establish the basis upon which the County will require a contribu-
tion from private developers or other jurisdLctions for the costs of
installing a traffic signai or accept additional contributions frcm
individuals, organizations or private developers to accelerate the
installation of a traffic signal the following policy is adopted.
Policy
It is the policy of the Board of Supsrvisors that:
.1. At intersections where one or more of the approaches to the inter-
sections are under the jurisdiction of ancther governmental
entity and such intersections nieet the nationally accepted
warrants for the installation of a traffic signal, the costs of
the installation shall be shared by the County and the other
governmental entity. The percentage of the costs to be paid by
each jurisdiction shall. be directly related to the number of
approaches to the intcrsccfiGn txdcr the control of either the
County or the other governmecca1 entity.
For example, an inccrsection i.5 ti7hich two cf thc approaches are
within n City Limits ;ind tmo wirhin the unincorporated arc8 would
bc financcd by cqm1 contri1:u:i::ns fron rnch jurisdiction.
Subject Participation by Icdividuals, Organiza-
cions, Private Developers, or other Jurisdictions
2. When it is determined that a private development will generate
substantial traffic at a specific intersection the County will
require from the developer a contribution toward the cost of tk
installation of a traffic signzil. The zmount of the contribution
shall be based upon an acalysis of the traffic which will be
generated by the development. Until warrants are met for a
signal installation project, and until the reiative priority of
the project is such as to justify the expenditure of any 7ubli.c
funds necessary to the project, the developer's contributions
will be retained for the project in the Public Works Adminis-
trator's Trust Fund.

3. If an individual, developer or organizatim indicates a willing-
ness to provide additional contributions to accelerate the
installation of a traffic signal at a location which mee'ts traffic
signal warrants but is not high enough on the Signal Priority
List to justify the budgeting of County funds for the project,
the proposal will be reviewed cn an individual basis by the
County Engineer and a recommendation for participation will be
forwarded to the Board of Supervisors fcr their consideration.
