Per your requcst, wF have revised the City Standards to incorporate
changes r,n,' ,dd i c i ons nf_�cessa ry to bring the old standards up to -date.
Most of ti-, +'rang-, represent chi%ages due to minor differences in Cicy
ordinnncc, s, oepartmcntal policies, maintenance operations, equipment
advances and net, Engineering and Planning Depa rtrnen't practices. in
addition, the revised standards contain maor changes in the street
lighting and landscape median standards, and an entirely new provision
to allow, for v�.riancas to the street cicsign standards.
As you knc,w, the current policy for ; eet: lighting is to use high
pre5SLI1%:; sodium lamps aird this is refler;ted in the revised standards.
We have also attempted to redarce the overall er,argy consuription of
street lights by reducing i ightlnc, levels along road•,�,ayc through open
space and industrial areas aiid requiring special consideration around
sens;tive recreational and %flidiife habitats. The second = jor change
is the establishment of a new median standard complete with landscape
and 'irrigation guidelines. Thc;re has been some, disagreement with t
Parks and Recreation Dvnartment as to the specifics of the median design,
but w,_- have inco poi ated most of their requests and have reached a
tentative acceptance of tho Hnal design.
Porentially, the most controversial item is the inclusion of a new,
procedure to aline, for variances to the City Standards. The new var-
iance procedura is based on the same process used by the Planning Depart-
ment for a vrriance to the zoning ordinance. Essentially, the process
reruires that the Planning Commission !Hake five findings before approving
a variance to th City Standards, These findings are that there be
unusual circumstances with no drainage problems or traffic conflicts and
that tine variance nod be detr•iniental to public safety or adversely affect
the comprehensive general plan.
The v�iriance procedure; would he applicable to both ( isting streets and
proposed roadways, if re.ques ted at the time a ten tea t i ve map is submitted.
There appears to be no conflicts in this a9proa6h with the general plan. •
in fact, the Ciruclotion Flcwunt of the General Plan states in reference
to their specific roadvday des i +oriat i ons that their "recommendations i i 1 us-•
trat:e reasonable and desirai:lc standard:., but it should be recognized that
cow,promises are s,riaetimes necessary in order to m::intain a practical
appiIol.ch and to accommodate the variations which are a part of community
D
-2-
We feel the variance approach would be the most reasonable and just
manner for the City to allow safe and creative variations to an otherwise
rigid set of standards.
There are many .existing roads in the City on which this procedure could
have potential impact. The most prominent of these are Highland Drive,
Adams Street, Jefferson Street East of Interstate 5, Carlsbad Boulevard,
E1 Camino Real, and many other local and collector streets located
primarily in the old part of town. The standards for the development
of.Occan Street have recently been set by Council as have the standards
for Maple Street. The standards for Tamarack Avenue from Carlsbad Blvd
to Park Drive we e basically set in the Geometric Design Study made of
that street in 1977.
It is not known exactly what impact the variance procedure will have on
future street development. It can be assumed the impacts will: be greatest
in residential estate zones, around the Lagoons and on hillsides. Con-
cerning the latter case, this revision could obviate the need for separate
hillside standards by allowing developers to reduce widths through the
variance procedure.
Concerning the question of.private roadways,•it is felt this problem
cannot be completely handled by these standards alone. Perhaps a better
way would be to use the minimum lane widths found in the Planned Unit
Development Section of the Zoning Code, together with the standards
variance procedure discussed previously. One suggestion has been made
to give the City Engineer the decision -making -ability on the variance
where private roads are concerned. The Planning Commission would have
the chance to review the City Engineer's decision as part of their normal
project review process.
One other problem brought to our attention concerns the parking of recreation
vehicles on residential streets. It has been suggested that perhaps the
curb -to -curb widths be widened as much as four feet to accommodate these
vehicles. It is felt by the Design Section that the added cost to the
developer for such a solution would not be worth the marginal benefit
derived from the added passing width. Our Traffic Engineering Aide
indicates he has no recollection of a parked recreational vehicle being
the cause for an accident in the City in the last year. A somewhat simpler
and less expensive answer to the problem would be to create an ordinance
limiting the, distance a truck or recreational vehicle may exiend into the
roadway and then cite the offending vehicles.

SUBJECT: Street Standards
Attached is a copy of the street standards used by the
Engineering Department. The standards that are outlined in
wide, black lines are taken directly from the General Plan.
The remaining street standards are based on engineering and
traffic safety principles.
The General Plan does allow for flexibility in its stand-
ards. Specifically, the Circulation Element states that
"...experience has shown that best results can be gained
from the consideration of established standards as guides as
to what is reasonable or desirable rather than as inflexible
rules." (Page 8)
There is no "grandfather clause" which requires existing
roads to be brought up to standards. However, the first
policy of the Circulation Element is to "...improve the
operational efficiencies of streets by using modern design
standards and the latest available technology." (Page 2)
This would seem to justify requiring streets and roads that
are not efficient in their operation to become so.

i B. Street Function s Standards
Pasl- practice has been to establish arbitrary standards for right-of-
way widths, pavement sections, parkway widths„ etc., for the various
classifications of streets. However, experience has shown that better
results can be gained from the consideration of established standards
as being guides as to what is reasonable or desirable rather than as
inflexible rules. Right-of-way requirements and necessary street widths
are directly related to the function a roadway is to serve, to the type
of abuttina development, to the traffic volumes anticipated to be carried,
and to the possible provision of facilities for other purposes such as
bikeways. The following is a description of the functions and standards
of the various categories of streets into which Carlsbad's circulation
system has been divided:
1. Local Streets: The principal purpose of a local street is to pro-
vide vehicular, pedestrian and bicycle access to property abutting
the public right of way, and moving traffic is 'only a secondary
function of the local street. Since land service is its primary
purpose, the local street should not carry through traffic, and
buses and heavy trucks should be excluded except where the local
street is in a commercial or industrial area of the City.
Cross sections of local streets vary with building practices, abut-
ting land uses, parking requirements, planting of street trees, and
other considerations. Where both sides of the street are served
equally, the common right of way width for a local; street is 60 feet
with a pavement width 36 feet in single-family residential areas
with scattered parking. In multi -family areas where there is more
or less continuous parking throughout the day and night, a minimum
of 40 feet of pavement is required in order that room for two mov-
ing lanes of traffic be available. In commercial areas, a minimum
pavement width of 40 feet is considered necessary as well, while in
industrial areas consideration of the predominant type of trucking
and whether or not maneuvering of trailers must be provided for
will dictate the width of pavement to be provided.
When pavement widths exceed 40 feet on local streets, right of way
must be increased above 60 feet correspondingly.
The overall system design of local streets can greatly affect traf-
fic since unduly long streets build up traffic volumes and cross
streets and intersections with acute angles are likely to cause
accidents. Good practice precludes carrying local streets into
arterials since such intersections create unnecessary friction points
and cause accidents and related congestion on the arterials. A far
better approach is to bring local streets into collectors which then
feed into arterials.
2. Collector Streets: The collector street is intended to serve as the
connecting link to handle traffic between local streets and the
secondary and major arterials. Additionally, collector streets
provide access to abutting property and will include those streets
which provide for traffic movements within a relatively small area
such as -a residential neighborhood. Generally speaking, traffic
using the collector streets will have an origin or a destination
within the local area.
A
M
Collector streets are anticipated to carry traffic volumes of up
to 5,000 vehicles per day. A collector street will normally have
one moving lane in each direction and may provide for on -street
parking; therefore, -a minimum pavement width of 40 feet is re-
commended, which can be accommodated within a 60 foot right of
way. In areas of the City where collectors, or sections of
collectors are anticipated to carry traffic volumes greater than
5,000 vehicles per day, pavement widths and rights of way may
be increased to facilitate the additional traffic. Collector
streets are not illustrated on the circulation element map since
they are only locally important and are related to the design con-
cepts utilized within a neighborhood.
3. Secondary Arterials: The main function of a secondary arterial
is to conduct traffic from collector streets to and from major
arterials or freeways. Land access is only a minor function of
a secondary arterial and, therefore, parking should be discouraged
and residential buildings should not have driveways entering a
secondary arterial. Additionally, it is good practice to avoid
situations where secondary arterials cross major arterials to form
a continuous system, since this might result in a tendency for
traffic to use the secondary arterial in lieu of a major arterial
for long trips.
Traffic volumes in the range of 5,000 - 20,000 vehicles a day
should be accommodated by secondary streets. Secondary arterials
usually have two moving lanes and one parking lane for each direc-
tion of flow and, therefore, require a pavement width of 64 feet
which requires a right of way of 84 feet. Where necessary, a
secondary arterial can fulfill the role of a major arterial
through the expedient of prohibiting on -street parking and establish-
ment of a central median divider, either raised or painted.
4. Major Arterials: The function of the major arterial is to provide
for the movement of traffic. The major arterial carries traffic
gathered from collector streets and secondary arterials.through-
out the community to other collector streets and secondary arteri-
als or to the freeways within or surrouding the community. Land
access and parking should be provided by other classifications
of streets. Traditionally, however, this separation between the
movement of traffic and the need to serve adjacent land uses has
not been well recognized. To encourage this recognition and to
move traffic efficiently and safely, adequate medians should be
provided and the number of'driveways and cross street intersections
should be minimized, on -street parking should be eliminated where -
ever possible, and off-street parking for adjacent development
should be provided.
Traffic volumes in excess of 20,000 vehicles a day necessitate the
construction of major arterial streets to carry such volumes
safely and efficiently. Major arterials will generally have four
lanes of moving traffic and, depending upon adjacent development
and service needs, may or may not have parking lanes. Where
parking lanes are provided, major arterials will have an 82-foot
wide curb separation within 102 foot right of way. An 18 foot
median divider may be provided.

10
A divided arterial provides an outstanding opportunity to improve
the appearance of the street and of the community by attractively
landscaping the dividing median.
5. Prime Maior Arterials: The primary and most important function
of prime major arterials is to move large volumes of vehicles
including automobiles, trucks and buses; and, as its name implies,
is should handle longer through trips.
The facility will be able to carry traffic volumes in excess of
40,000 vehicles per day, Prime major arterials will be able to
be expanded to six lanes or moving traffic. This facility may be
designed with a curb separation within a 126 foot right of way.
Also included is an 18 foot median divider.
6. Freeways: The term "freeway" means an access --free, high speed
road with grade separated interchanges; and it has only one function -
to carry traffic. It is intended to expedite movement between
relatively distant areas in a community, metropolitan area, or
region.
The freeway is a major visual element in the City and in cut,
at grade, or on fill, it constitutes a major barrier separating
land uses on one side from those on the other.
Planning, design, and construction of freeways in California are
usually undertaken by the State Department of Transportation and,
as a result, fall outside the jurisdiction of a city. Nonetheless,
the City should play an important role in the selection of freeway
routes, in the determination of the number of lanes required to
carry projected traffic loads, and encouraging the installation
and maintenance of attractive landscaping so that the freeway
right of way can become integrated with and be an attractive part
of the community visual scene.
The street cross section standards discussed above are suggestions
which will provide the quality of traffic flow and capacity that future
traffic volumes will require. All intersections of major and second-
ary arterials will require signalization at an early date and the
provision of left turn lanes will substantially increase capacity.
Another concept which should be considered with respect to the inter-
section of major and secondary arterials is the acquisition of addi-
tional right of way and construction of widened pavements at the
approaches to intersections so that separate turning lanes, both for
left and tight turns, can be installed with the resultant material
increase in traffic carrying capacity.
The above recommendations illustrate reasonable and desirable standards,
but it should be recognized,that compromises are sometimes necessary in
order to ma i nta in a practical approach and to accommodate the variations
which are a part of community growth.
The accompanying chart (page 12) illustrates the relationship between
the movement and access functions of the various components of a
circulation system. The major thrust of the chart is to show that,
as the movement function or volume of traffic handled increases, the
amount of local access (driveways and number of intersections) should
be reduced.
Except where street rights of way already exist, the alignments of
streets shown on the circulation system map (page 13) are general
only, and the map is not intended to portray a specific location.
Precise alignments can only be developed after complete and detailed
design studies have been undertaken.

18.40.010 Findings, pur ose and intent. (a) The city
council finds as follows:
(1) There is a lack of adequate curbs, gutters, side-
walks and strecUs in various areas of the city which is pre-
judicial and dangerous to the public health, safety, and
welfare of the inhabitants of the city.
(2) The lack of improved sidewalks in the city in many
instances forces pedestrians, including shcool childrrn, to
walk in the streets and to be subject to the hazards of vehicu-
lar traffic.
(3) The -lack of improved sidewalks during rainy weath-
er has caused unhealthy conditions resulting from pedestrians
walking through mud or water along streets or dirt sidewalks.
(4) Streets and highways of inadequate width and de-
sign hinder vehicular movoment and constitute a hazard to the
safety and health of user: .
(5) The lack ofcurbs, stoim drains and other street
improvements results in poor drainage and a collect -ion of
filth and waste.
(6) The lack of improved streets impedes the opera-
tion of fire trucks, police cars and other emergency vehicles
as well as the operation of street sweepers and refuse col-
lection vehicles.
(b) It is the purpose of the city council in adopting
the provisions of this chapter to:
(1) Impose rea.son.able requirements of dedication and
improvements upon persons engaged in the development, construc-
tion, reconstruction or remodel-ng of buildings which tend to
result in increased dcm ands upon the existing public rights -
of -way and streets and highways in the city thereby increasing
the danger to the public hualL-h „ safety and welfare; '

(2) Extend the basis, requirements of the Subdivision
Map Act ljy establishing standards and requirements for dedica-
tion and improvements in conricct.i.on with the development of land
in which no subdivision is involved,
(3) Alleviate the undesirable situation found to exist
in subscot-ion (a) by spreading the cost of public improvements
upon abutting property in an equitable manner and by causing the
installation of those improvements required by the city to
serve property about co be de-.veloped at the time of its develop-
ment.
(c) The city council intends to require, in accordance
with the provisions of this chapter, the. dedication of portions
of the public rights -of -way including streets, highways, alleys
and storm drain, facilities and the construction of improvements
contiguous to the property from the property line to the center-
line of the public rights -of -way as necessitatQd by the nature
and type of, building or structi?re being constructed and the use
to which the property is being put. (Ord. 80G7 51(pa.r_t), 1976).
18.40.020 Definitions. For the purposes of this chapter,
the following words and phrases shall have the meaning respec-
tively ascribed in them by this section:,
(1) "Alley" means a public or private way permanently
reserved as a secondary means of access to abutting property.
(2) "Bui.lding" includes any building, structure or
dwelling of which the cost price of erecting the same is in
excess or the sum of ten thousand dollars as determinated by
building permit valuation.
(3) "Improvements" includes sidewalks, gutters, pavement,
driveways, curbs, streets, alleys, storm drain facilities,
water systems, sanitary sewer systems, street lighting, fire
protection installation and pavement transitions.
(4) "Person" means any person, firm,.partnership, asso-
ciation, corporation, company or organization of any kind.
The term "person" also includes any owner, lessee or agent
constructing or arranging for the construction, modification, or
alteration of a building or dwelling. (Ord. 8067 §l(part,),
1976).
18.40.030 Dedications required. (a) Any person who
constructs or causes to be constructed any building in the
city shall have provided by means of an offer of dedication
or other appropriate conveyance as approved by the city attor-
ney the rights -of -way necessary for the construc_l-.ion of any
street, highway, or alley as shown on the circulation element
of the general plan, any applicable speci:tic plans, or as
otherwise required by the city enginecaz in accord with an
established street system or plan. Rights -of -way shall also
be provided for any improvements to existing facilities in-
cluding rights--of-way for storm drains or other required
public facilities. All rights -of -way shall be accompanied by
a title examination report and be free of all liens and on -

(b) The dedications required by subsection (a) shall.
also apply to any person who alters, enlarges, expands, or
causes to be altered, enlarged, or expanded any building in
the city if the cost of such •work exceeds the sum of ten
thousand dollars as determined by building pe..mit valuation.
I(c) The dedications required by this chapter shall be
made prior to issuance of the building permit for the sub-
ject property.
. (d) Prior to the issuance of the building permit for
the subject project, there shall be paid to the engineering
department a fee of forty dollars for processing the offer
of dedication.. (Ord. 7058 53, 1979; Ord. 8067 §1(part),.
1976) .
18.40.040 Public improvements required. (a) Any
person who constructs or causes to be constructed any build-
ing in the city shall construct all necessary improvements
in accordance with city specifications upon the property
and along all street frontages adjoining the property upon
which such building is constructed unless adequate improve-
ments already exist. In each instance, the city manager
shall determine whether or not the necessary improvements
exist and are adequate. Each building permit application
shall be so endorsed at the time it is issued.
(b) The improvements required by subsection (a) shall.
also apply to any person who alters, enlarges or eiTands or
causes to be altered, enlarged or expanded any building in
the city if the cc,st of such work exceeds the sum of ten
thousand dollars, except work on single• -family dwellings
located in the R-A and R-1 zoi,es. (Ord. 8067 51(part), 1976).
18.40.050 Public utility relocations. In the event
the city manager determines that the contemplated construc-
tion of improvements as required by this chapter in indivi-
dual cases will necessitate the relocation or alteration of
public utility facilities, including but not limited to gas,
electricity, telephone and water, he may require the person
requesting the building permit to produce satisfactory evi-
dence that such person has made arrangements wit}. such public
utili.ty.company for the relocation or modification of,such
public utility facilities. (Ord. 8067 §ltpart), 1976).
18.40.060 Construction of public improvements. If the
city manager determines that public improvements are required,
these public improvements shall be designed to city standards
and their construction guaranteed by an improvement agreement
secured by a bond or cash deposit prior to issuance of a
building permit for the subject property. If the building
permit is not exercised, the improvement obligation shall.
'terminate and the security shall be returned. The city man-
ager is authorized to execute such agreements on behalf of
the city. (Ord. 8067 51(part), 1976).

18.40.070 Deferral of improvement requirements. Upon
written appl.ic". .3 on, the. by written order may
defer any of the improvements required by th.i.s chapter if he
finds that the: public Health, safety and welfare of tl?e in-
habitants of the city will not be endangered by the deferment
of the construction of the improvements and that any one of
the following e-xists:
(1) There is a lack of adequate data in regard to the
grades, plans or surveys which complicate the construction of
the improvements and indicate they should be dr;ferred to a
later time.
(2) The construction of —the improvements is included
in an approved or pending assessment district or otherwise
guaranteed. as provided by city ordinance.
(3) Construction of the improvements would be incom-
patible with the present state of the neighborhood's develop-
ment or be impractical or premature because of'the condition
