the Chief determines is or reasonably may be necessary to
protect any building or structure on the land to be de-
veloped against fire.
b. ~'To developy' land shall mean to make any improvements or
do any work upon such land which would require the issuance

f. ~Land~ shall mean any lot~ parcel, acreage or building site,
or any other land or portion thereof embraced within a com-
mon plan of development, whether improved or unimproved.
Section 2. On-Site Facilities may be required:
When any land is developed in such a manner that all or a substan-
tial part of any building or structure thereon is or becomes in excess
of the distance from an adequate water supply and/or facilities required
for fire protection as hereinafter provided, the owner, developer or
agent shall provide such adequate water supply and/or fire protection
facilities as shall be determined necessary pursuant to this Ordinance.
Section 3. Certain Plans Reviewable by Fire Department:
Except for those for R-1 and R-2 Zones as designated by the Zoning
Ordinance o~ the City of South San Francisco, one set of plans submitted
by applicant for a building permit shall be forwarded to the Fire Chief
for review.
Section 4. Review by Fire Department:
When plans are submitted pursuant to Section 3, the Fire Chief
shall review same and determine whether any building or structure on the
land to be developed is or shall by virtue of said development become
in excess of the distance as hereinafter provided from an adequate water
supply and/or facilities. If upon such review it is determined either
that additional water supply and/or fire protection facilities are not
required or that they are adequately provided for in the plans, the Fire
Chief shall endorse his approval thereon. If adequate provision for such
water supply and/or facilities is not made, the Fire Chief shall either
disapprove said plans and indicate to the Building Department in writing
wherein they are deficient (in which case any revised plans shall be re-
submitted to the Fire Department) or approve said plans subject to con-
ditions that deficiencies noted be corrected. If the Fire Chief fails
to take the required action within five working days after submission of
the plans to him, then the Building Inspector shall give the Fire Chief
notice in writing that the plans shall be deemed approved by the Fire
Chief unless a report and recommendation is filed within 48 hours af-
ter receipt of the notice, and should said report and recommendation
not be so filed, the plans shall be deemed approved by the Fire Chief.
Section 5. Adequate Water Supply:
Adequate water supply shall be determined by applying the formula
and schedules contained in Table A entitled ~'Flow Required - In Gallons
Per Minute~ and Table B entitled ~'Area Served By One Hydrant". The
Fire Chief shall determine the factor flow required in gallons per min-
ute by applying the formula set forth in Table A and upon determining
that factor shall locate it in the left-hand column of Table B entitled
~'Fire Flow Required in Gallons per Minute", after which he shall locate
in the adjacent column the applicable average area per hydrant in square
feet and the approximate distance between hydrants in feet.

not less than 20 pounds, except where the building is equipped with auto-
matic sprinklers dependent upon the distribution mains for supply, in
which case the required fire flow shall be available at a residual pres-
sure which will correspond to 15 pounds on the top line of the sprink-
lers.

*These are the approximate distances from the hydrant in question to the
nearest four hydrants, each of which is located along one of the four
branches of the two streets intersecting at this point. It is assumed
that the city blocks are square and that the streets cross at right angles
to each other.
Section 6. Availability of Supply:
City hydrants shall be taken into account in determining whether
an adequate water supply and/or facilities exist with reference to a
given building, except that no hydrant or other water source shall be
counted as contributing to said supply if in the judgment of the Fire
Chief said source is not dependable, not readily accessible, not adapt-
able to use by City equipment~ or not within reasonable working distance
of the building, or portion of the building dependent for fire protection
upon said hydrant or source. A reasonable working distance shall be
deemed not to exceed 200 feet except where, in the judgment of the Fire
Chief, the application of such rule under the circumstances would be
impracticable.
Section 7. On-Site Facilities to be Provided:
The Fire Chief may prescribe that the development include tile in-
stallation of such on-site fire protection facilities as in his judgment
are necessary to provide an adequate water supply on t~e land to be de-
veloped; said installation shall be at the expense of the owner or de-
veloper. The location of all hydrants shall be approved by the Fire Chief.
Nothing herein shall prevent the installation of all or a portion of
said facilities on land adjoining the land to be developed if the Fire
Chief shall approve such installation as being in all respects adequate
under the provisions of this division and the conditions of dedication
and access herein are met. Should applicant make use of adjoining land
for such purposes, he shall file with the Fire Chief a copy of the Grant
of Easement for said purposes.

Section 8. Clear Area for Mains and Facilities:
Should on-site facilities be required, the plans shall show a
clear area of not less than five feet in width for the location and
placement of said facilities. On-site installations shall be maintained
at applicant's expense. The Fire Chief may periodically inspect said
facilities and if upon inspection he determines that they are defective
or not maintained to the standard required by the Fire Department of the
City of San Francisco for such facilities, he shall give notice in writ-
ing to the applicant or owner of such facilities requiring that their
condition be repaired and that they be brought up to the standard of
fire protection facilities maintained by the Fire Department. Should
the owner fail to comply with the notice within ten days or reasonable
extensions of time thereafter granted by tt~e Fire Chief, then the Fire
Chief may have the facilities repaired at the expense of the owner.
Section 9. Access for Firefighting Equipment:
Whenever any hydrant or other appurtenance for use by the Fire De-
partment is required to be installed under the provisions of this divi-
sion, there shall be included in said development plans and delineated
thereon adequate provision for access to and from every such hydrant
and appurtenance by City firefighting equipment. Said access shall be
in the form of an improved, permanently maintained roadway, or of open
paved or surfaced area, or of any combination thereof, maintained at
all times in such a manner that there shall be kept clear and unobstruc-
ted an access of at least 22 feet in width at all points along the dist-
ance from the public street to any such hydrant or appurtenance. When
the total length of any such access way exceeds 350 feet and culmin-
ates in a deadend or cul-de-sac, an area shall be provided within the
end one-third thereof sufficient to provide an equipment turning radius
of 30 feet,
Section 10. Final Inspection:
No final inspection under the Building Code as to all or any
portion of the development shall be deemed completed and no certifi-
cate of occupancy shall issue unless and until the installation of the
prescribed facilities and access ways have been completed and the
final approval thereof of the Fire Department given as provided herein.
Section 11. Access to Facilities to be Kept Open:
After said facilities have been installed as required by the Fire
Chief, the following sh~ll apply to obstructions, unlawful use and
parking:

or parking areas where curbs exist, said curbs shall be
painted or otherwise appropriately marked by the owner to
prohibit parking for a distance of 15 feet in either di-
rection from any such hydrant. In such cases where curbs
do not exist, there shall be appropriate markings painted
on the pavement, or signs erected, or both, giving notice
that parking is prohibited for a distance of 15 feet from
any such hydrant.
When such areas are signed or marked as provided herein,
no person shall park or leave standing a vehicle within 15
feet of any such fire hydrant.
