authorities of any city which is on a natural island with an area in
excess of 20,000 acres and which is within a county having a
population in excess of 4,000,000, may, if they determine such rules
and regulations to be necessary in view of the special problem

and regulations authorized by this subdivision shall be consistent
with the responsibility of local government to provide for the health
and safety of its citizens.



21101.2.  Local authorities may adopt rules and regulations by
ordinance or resolution to provide that if a peace officer, as
defined in Chapter 4.5 (commencing with Section 830) of Title 3 of
Part 2 of the Penal Code, determines that the traffic load on a
particular street or highway, or a portion thereof, is such that
little or no vehicular flow is occurring and, additionally, if the
peace officer finds that a significant number of vehicles are not
promptly moving when an opportunity arises to do so, then the peace
officer may divert vehicles, excepting public safety or emergency
vehicles, from that street or highway, or portion thereof, subject to
traffic congestion until such time as reasonably flowing traffic is
restored.



21101.4.  (a) A local authority may, by ordinance or resolution,

resolution, that all of the following conditions exist:
   (1) Continuation of the temporary closure will assist in
preventing the occurrence or reoccurrence of the serious and
continual criminal activity found to exist when the immediately
preceding temporary closure was authorized.  This finding and
determination shall be based upon the recommendation of the police
department or, in the case of a highway in an unincorporated area, on
the joint recommendation of the sheriff's department and the
Department of the California Highway Patrol.
   (2) The highway has not been designated as a through highway or
arterial street.
   (3) Vehicular or pedestrian traffic on the highway contributes to

21101.6.  Notwithstanding Section 21101, local authorities may not
place gates or other selective devices on any street which deny or
restrict the access of certain members of the public to the street,
while permitting others unrestricted access to the street.
   This section is not intended to make a change in the existing law,
but is intended to codify the decision of the Court of Appeal in

   This section shall become operative on January 1, 1990.



21102.  Local authorities may adopt rules and regulations by
ordinance or resolution closing to vehicular traffic that portion of
any street or highway crossing or dividing any school ground or

jurisdiction such closing is necessary for the protection of persons
attending such school or school grounds.  The closing to vehicular
traffic may be limited to such hours and days as the legislative body
may specify.  No such ordinance or resolution shall be effective

street or highway affected, nor in the case of state highways, until
such ordinance or resolution is approved by the Department of
Transportation.



21102.1.  Notwithstanding any other provision of law, local
authorities may, by ordinance or resolution, adopt rules and

which is submitted to the Department of Transportation by a local
legislative body in complete draft form for approval prior to the
enactment thereof is effective as to any state highway or part
thereof specified in the written approval of the department.
   This section does not preclude the application of an ordinance or
resolution adopted under Section 21101 or subdivision (d) of Section

impose a fine or penalty of up to one hundred dollars ($100) for a
violation of this code.


21105.  No rule or regulation adopted under Sections 21100 or 21101

21107.  The provisions of this code shall not prevent any city from
adopting rules and regulations by ordinance or resolution, regulating
vehicular traffic on privately owned and maintained roads located
within the boundary of such city, except that no such ordinance or
resolution shall be effective until signs giving notice thereof are
posted on the roads affected.  The provisions of this section shall
not apply to any city in which there are publicly maintained city
streets.



21107.5.  (a) Any city or county may, by ordinance or resolution,
find and declare that there are privately owned and maintained roads
as described in the ordinance or resolution within the city or county
that are generally held open for use by the public for vehicular
travel and which so connect with highways that the public cannot
determine that the roads are not highways.  Upon enactment by a city
or county of the ordinance or resolution, this code shall apply to
the privately owned and maintained road, except as provided in
subdivision (b).
   (b)  No ordinance or resolution enacted under subdivision (a)
shall apply to any road on which the owner has erected a notice of a

road involved.
   (b) Notwithstanding the provisions of subdivision (a) no ordinance
enacted thereunder shall apply to any road described therein on
which the owner has caused to be erected a notice of such size, shape

and maintained and that it is not subject to public traffic
regulations or control.

find and declare that there are privately owned and maintained roads
as described in the ordinance or resolution within the city or county
that are not generally held open for use of the public for purposes
of vehicular travel but, by reason of their proximity to or
connection with highways, the interests of any residents residing
along the roads and the motoring public will best be served by
application of the provisions of this code to those roads.  No
ordinance or resolution shall be enacted unless there is first filed
with the city or county a petition requesting it by a majority of the
owners of any privately owned and maintained road, or by at least a
majority of the board of directors of a common interest development,
as defined by Section 1351 of the Civil Code, that is responsible for
maintaining the road, and without a public hearing thereon and 10
days' prior written notice to all owners of the road or all of the
owners in the development.  Upon enactment of the ordinance or
resolution, the provisions of this code shall apply to the privately
owned and maintained road if appropriate signs are  erected at the
entrance to the road of the size, shape, and color as to be readily
legible during daylight hours from a distance of 100 feet, to the
effect that the road is subject to the provisions of this code.  The
city or county may impose reasonable conditions and may authorize the
owners, or board of directors of the common interest development, to
erect traffic signs, signals, markings, and devices which conform to
the uniform standards and specifications adopted by the Department
of Transportation.
   (b) The department shall not be required to provide patrol or

23103, and 23109 and the provisions of Division 16.5 (commencing with
Section 38000) shall apply to privately owned and maintained
offstreet parking facilities, except as provided in subdivision (b).

   (b) Notwithstanding the provisions of subdivision (a), no

owned and maintained roads within a mobilehome park, as defined in
Section 18214 of the Health and Safety Code, or within a manufactured
housing community, as defined in Section 18801 of the Health and
Safety Code, within the city or county, or city and county, that are
generally not held open for use by the public for vehicular travel.
Upon enactment of the ordinance or resolution, the provisions of this
code shall apply to the privately owned and maintained roads within
a mobilehome park or manufactured housing community if appropriate
signs are erected at the entrance or entrances to the mobilehome park
or manufactured housing community of the size, shape, and color as
to be readily legible during daylight hours from a distance of 100
feet, to the effect that the roads within the park or community are
subject to the provisions of this code.  The city or county, or city
and county, may impose reasonable conditions and may authorize the
owners of the mobilehome park or manufactured housing community to
erect traffic signs, markings, or devices which conform to the
uniform standards and specifications adopted by the Department of
Transportation.

first filed with the city or county a petition requested by the owner
or owners of any privately owned and maintained roads within a
mobilehome park or manufactured housing community, who are
responsible for maintaining the roads.

hearing thereon and 10 days' prior written notice to all owners of
the roads within a mobilehome park or manufactured housing community
proposed to be subject to the ordinance or resolution.  At least
seven days prior to the public hearing, the owner or manager of the
mobilehome park or manufactured housing community shall post a
written notice about the hearing in a conspicuous area in the park or
community clubhouse, or if no clubhouse exists, in a conspicuous
public place in the park or community.
   (d) For purposes of this section, the prima facie speed limit on
any road within a mobilehome park or manufactured housing community
shall be 15 miles per hour.  This section does not preclude a

been conducted within the community supporting that request.
   (e) The department is not required to provide patrol or enforce
any provision of this code on any privately owned and maintained road
within a mobilehome park or manufactured housing community, except
those provisions applicable to private property other than by action
under this section.

Department of Transportation shall conduct a traffic and engineering
survey which includes an analysis of the relative risks to public
safety in determining the feasibility of reasonable alternative
routes.

Code, on privately owned and maintained roads or ways within areas
which would be a residence district if the road or way were a public
highway, or, with the consent of the owner, on publicly owned and
maintained roads and ways within areas which are not owned by such
local authorities.  The rules or regulations shall not be effective
until appropriate signs giving notice thereof are posted along the
roads or ways affected.



21112.  Local authorities may by ordinance license and regulate the
location of stands on streets and highways for use by taxicabs and

21114.  If a local authority finds that a city street or county road
under its jurisdiction adjacent to an airport has been specifically
designed and constructed, with the prior approval of the local
authority, so as to safely permit the use thereof by regular
vehicular traffic and also the taxiing of aircraft thereon between
the airport and the place where such aircraft are hangared or tied
down, the local authority may by resolution or ordinance designate
such street or road or portion thereof for such combined use and
prescribe rules and regulations therefor which shall have the force
of law.  No such street or road shall be so designated for a distance
of more than one-half mile from the airport, provided, the finding
of the local authority in this respect shall be conclusive.  Upon
such designation becoming effective, it shall be the sole
responsibility of the local authority to enforce the provisions of
the Vehicle Code and all rules and regulations adopted by it upon
such street or road.  Upon such designation becoming effective it
shall be lawful to taxi aircraft upon such street or road in
accordance with the rules and regulations prescribed as aforesaid and
said aircraft need not be licensed under this code or comply with
other provisions thereof.


21114.5.  Notwithstanding Section 21663 or any other provision of
this code, local authorities may, by ordinance, authorize the
operation of electric carts by physically disabled persons, by
persons 50 years of age or older, or, while in the course of their
employment, by employees of the United States Postal Service, state
and local governmental agencies, or utility companies, on public
sidewalks.  Any ordinance shall, however, contain provisions
requiring any disabled person or person 50 years of age or older who
owns or leases an electric cart to apply to the local authority for a
permit and an identification sticker to so operate the cart, and
requiring the person to affix the sticker to the cart in order to
operate it on the sidewalk.  The permit and sticker shall become
invalid if the person ceases to operate, own, or lease the cart.
   This section does not apply to devices described in subdivision
(b) of Section 415.


21115.  (a) If a local authority finds that a highway under its
jurisdiction is located adjacent to, or provides access to, a golf
course and between the golf course and the place where golf carts are
parked or stored or is within or bounded by a real estate
development offering golf facilities and is designed and constructed,
so as to safely permit the use of regular vehicular traffic and also
the driving of golf carts on the highway, the local authority may,
by resolution or ordinance, designate the highway or portion of the
highway for combined use and prescribe rules and regulations that
shall have the force of law.  No highway shall be so designated for a
distance of more than one mile from the golf course if the highway
is not located within a development or beyond the area of a
development, provided, the finding of the local authority in this
respect shall be conclusive.  Upon the designation becoming effective
it shall be lawful to drive golf carts upon the highway in
accordance with the prescribed rules and regulations.  The rules and
regulations may establish crossing zones and speed limits and other
operating standards but shall not require that the golf carts conform
to any requirements of this code with respect to registration,
licensing, or equipment, except that if operated during darkness the
golf cart shall be subject to the provisions of Section 24001.5
regarding equipment.
   The rules and regulations shall not be effective until appropriate
signs giving notice thereof are posted along the highway affected.
   A "real estate development offering golf facilities," for purposes
of this section, means an area of single-family or multiple-family
residences, the owners or occupants of which are eligible for
membership in, or the use of, one or more golf courses within the
development by virtue of their ownership or occupancy of a
residential dwelling unit in the development.
   (b) For purposes of this section, a "golf cart" includes a
low-speed vehicle.



21115.1.  (a) Notwithstanding Section 21115, a local authority may,
by ordinance or resolution, establish crossing zones, for use by golf
carts at any time other than during darkness, on any street, other
than a state highway, that has a posted speed limit of 45 miles per
hour or less and that is immediately adjacent to a golf course.  The
crossing zones shall be at an angle of approximately 90 degrees to
the direction of the roadway.  The ordinance or resolution shall not
become effective until submitted to the law enforcement agency having
primary jurisdiction over the street, the law enforcement agency
finds and determines that the conditions pertaining to that street,
with the addition of proper signs, markers, or lighting, or any
combination of those, will permit the establishment of a golf cart
crossing with reasonable safety, and the signs, markers, or lighting
specified by the law enforcement agency are in place.
   (b) Subdivision (a) does not constitute precedent for the
operation of golf carts on any street or highway other than in a
crossing zone established pursuant to subdivision (a).
   (c) For purposes of this section, a "golf cart" includes a
low-speed vehicle.



21116.  (a) No person shall drive any motor vehicle upon a roadway
located on a levee, canal bank, natural watercourse bank, or pipeline
right-of-way if the responsibility for maintenance of the levee,
canal bank, natural watercourse bank, or pipeline right-of-way is
vested in the state or in a reclamation, levee, drainage, water or
irrigation district, or other local agency, unless such person has
received permission to drive upon such roadway from the agency
responsible for such maintenance, or unless such roadway has been
dedicated as a public right-of-way.
   (b) For this section to be applicable to a particular levee, canal
bank, natural watercourse bank, or pipeline right-of-way, the state
or other agency having responsibility for maintenance of the levee,
canal bank, natural watercourse bank, or pipeline right-of-way shall
erect or place appropriate signs giving notice that permission is
required to be obtained to drive a motor vehicle thereon and giving
notice of any special conditions or regulations that are imposed
pursuant to this section and shall prepare and keep available at the
principal office of the state agency or other agency affected or of
the board of such agency, for examination by all interested persons,
a written statement, in conformity with the existing rights of such
agency to control access to the roadway, describing the nature of the
vehicles, if any, to which such permission might be granted and the
conditions, regulations, and procedure for the acquisition of such
permission adopted pursuant to this section.
   (c) Nothing in this section prohibits the establishment of bicycle
paths or routes (as prescribed by Article 6.5 (commencing with
Section 5078) of Chapter 1 of Division 5 of the Public Resources
Code) on levees, canal banks, natural watercourse banks, or pipeline
rights-of-way.



21117.  (a) Local authorities may, notwithstanding Section 21101 or
21101.6, by written agreement approved by their legislative bodies,
transfer among themselves the responsibility for maintaining,
operating, or controlling public access to any highway under their
respective jurisdictions located in or adjacent to an ecological
reserve or an environmentally sensitive area within their respective
jurisdictions.
   (b) An agreement entered into pursuant to subdivision (a) may
authorize the local authority having responsibility for the highway
under the agreement to do all of the following:

same meaning as defined in Section 1584 of the Fish and Game Code,
and "environmentally sensitive area" has the same meaning as defined
in Section 30107.5 of the Public Resources Code.
