depth of 100 feet or more, If the shape of the lot or parcel is
other than the usual rectangular shape, or if such lot or parcel
is unusual in area, and the strict adherence to the above mentioned

connection fees noted on the official sewer maps on file in the
office of the City Engineer shall be paid.
Any fee paid pursuant to this section shall be paid into the
Sewer Connection Fund.
5212.2. same Same. Whenever a person desires or is required
to construct a pu is sewer of a capacity greater than that required
to serve such person's property and/or which will extend past property
which, at some future date, may connect thereto and be serviced there-
by, the City Engineer may make one of the following arrangements, de-
pendent upon which one of such arrangements may result in a more
equitable distribution of the construction costs to the property bene-
fited:
(a) He shall prepare an Engineer's estimate of such sewer con-
struction cost and may authorize an advance from the Sewer Connection
Fund to the person constructing such sewer. Such advance so authorized
shall be in an amount not greater than $3.00 per front foot for such
property which will not bear any cost of such construction but which
will benefit by such construction at such time as such property is
connected thereto. A notation shall be made on the official sewer
maps of the City specif.Vi.ng that, before any property not having
borne its share of such cost of construction shall be connected to
such sewer, there shall be paid into the Sewer Connection Fund, $3.00
for each front foot of such property to be so connected.
(b) He shall prepare an Engineer's estimate of the cost of the
sewer construction and prorate, according to benefits received, the
total cost of such sewer construction against the various properties
to be benefited by such construction. A notation shall be placed
upon the official sewer maps of the City that, prior to any such
property so benefited being connected to such sewer, the prorata
share charged against such property shall be paid into the Sewer
Connection Fund. Out of this fund, reimbursement shall be made to
the person or persons originally bearing the cost of such sewer con-
struction. This method of distributing the cost of such sewer con-
struction shall apply only when such sewer construction has been
financed by private funds.
(c) He shall prepare an Engineer's estimate of the cost of such
sewer construction and prorate, according to benefits received, the
total cost of such construction against the various properties to be
benefited by such construction. The City Engineer then may authorize
an advance to the person constructing such sewer an amount not greater
than the total of such benefits so assessed prorata egainst property
not contributing to the cost of such construction. A notation shall
be placed on the official sewer maps specifying that, before any
property so benefited and not having paid its prorata share of the
cost of such construction may be connected to such sewer, there
shall be paid into the Sewer Connection Fund such prorata share as
previously determined and set forth on said map.
5212.3. Same. Front ene e Bteefited. If only a portion of an
abutting pare s toBe d y such sewer connection, the
City Engineer may issue a permit for such a portion described in
the written application upon verification that only such portion
will be benefited by the sewer connection.
-5-
ordinance No. 79
yhe fees for a permit to make such a sewer connection shall be
calculated on the frontage of the portion of the parcel for which
the permit is issued.
In the event that any public entity other than the City requires
a connection charge or fee for use of a trunk sewer prior to the
Issuance of a permit by the City, the charge in the amount of $3.00
per front foot, required in this section, shall be reduced by the
amount of the charge or connection fee for the same frontage made
by the public entity.
5212.4. Same. Pa tent in Advance. The payment of the charges
prescribed by Sem on shall De made in advance, but before such
payment is made the City Engineer shall determine that there has been
compliance with the provisions of this chapter. Nothing in Section
5208.1 shall be deemed or constuued to apply to the issuing of a per-
mit for the construction of a house lateral or an industrial connection
sewer if the lot or parcel sought to be connected has been duly assessed
under special assessment proceedings for a public sewer unless the
sewer connection required provides benefit in addition to the benefit
received from the sewer for which the property was previously assessed.
5213. Connecta Cess ools or Se tic Tanks. No person shall
connect or cause o e connec a any cesspool seepage pit or sep-
tic tank to any main line sewer or to any house lateral leading

not be place3 closer than Tw6j2Y feet to the exterior wall of any
building or closer than twelve (12) inches to the surface of the
ground at any point in its course,
5216. Excavations. All excavations shall have sufficient width to
allow properwor�ans ip and permit adequate inspection, and shall be
supported in the manner set forth in the rules, orders and regulations
prescribed by the Industrial Accident Commission of the State of
California. Sheet piling and other timbers shall be withdrawn in such
a manner as to prevent caving of the walls of the excavation or dis-
turbance of the sewer.
5217. Excavation Tunnels. Where sufficient depth is available
r^ to permit, tunnels may be used between open out trenches, Tunnels
shall have a clear height of two (2) feet above the pipe`, and shall
be limited in length to one-half (1/2) the depth of the trench, but
with a maximum length of eight (8)) feet.
5218. Wet or Soft Ground. Before laying any sewer pipe in an
excavation in softs wet, or spongy soil, sufficient gravel or crushed
rock or other suitable base material to stabilize the subgrade shall
be placed in the bottom of the trench.
5219. High Ground Water. No person shall begin the work of house
lateral construct on In an area having a subsurface water level

such equipment before granting a permit.
