RESOLUTION NO. 81/-53
A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF REDDING
ESTABLISHING A SEWER SYSTEM SPECIAL BENEFIT CHARGE.
WHEREAS , the City of Redding, through its City Council, has
adopted a Master Sewer Plan; and
WHEREAS, the plan recognizes system deficiencies which are
uniquely confined to specific geographical areas , as shown by the
attached map; and
WHEREAS, elimination of the identified deficiencies in the
specific geographical areas is necessary to accommodate projected
growth which cannot be met by existing systems; and
WHEREAS, cost estimates have been prepared based upon the
need for specific improvements; and
WHEREAS, the fees proposed do not exceed the prorata share
of the amount of the cost of improvements within the specified
geographical areas which would be accessible on such property if
such costs were apportioned uniformly on a per acre basis
adjusted for land use considerations;
NOW, THEREFORE, BE IT RESOLVED that the City Council of the
City of Redding hereby establishes sewer system special benefit
charges as defined in Section 14. 16. 015 II of the Redding Munici-
pal Code for specific zones of deficiency, all as more specifi-
cally set forth in Exhibits A, B, C, D and E attached hereto and
made a part hereof. Said charges are to be levied against all G,
(A
lots or parcels created subsequent to July 1 , 1980 .

Si ECTAL BENEFIT ZONE
NORTH REDDING LIFT STATION
BENEFIT ZONE:
Subareas N-1 through N-22 tributary to the North Redding Lift Station as
depicted on the attached map and shown in the 1979 Master Sewer Plan.
DESCRIPTION OF PROJECT:
The installation of new 60 HP motors and pumps, variable speed motor
control system, electrical service panels, flow meter, and the construc-
tion of a 600,000 gallon emergency storage pond.
PURPOSE OF PROJECT:
To increase the pumping capacity of the lift station, to replace
outdated electrical control systems, and to construct a 600,000 gallon
emergency storage pond. As indicated in the 1979 Paster Sewer Plan, the
peak wet weather flow in 1979 was 80 percent of the effective pumping
capacity of the North Redding Lift Station. It was estimated at that
time that the lift station would be 100 percent capacity by 1982. The
1979 Master Sewer Plan recommended updating the lift station in 1981-82.
Modifications to the lift station was completed on February 4, 1983.
With these improvements completed, the lift station will have adequate
pumping capacity until 1990 or later depending on the rate of growth in
the North Redding service area.

SPECIAL BENEFIT ZONE
LIFT STATION NO. 2 MODIFICATIONS
BENEFIT ZONE:
Subareas E-25 , E-27, E-53, E-57, E-58, E-59, E-60, E-61, E-62, and E-63
tributary to Lift Station No. 2 as depicted on the attached map and
shown in the 1979 Master Sewer Plan.
DESCRIPTION 07 PROJECT:
Modification of Lift Station No. 2 , construction of 10-inch force main,
and 5,600 LF of 15- and 18-inch gravity trunk in Bechelli Lane from Lift
Station No. 2 to the South Bonnyview interceptor and the construction cf
an 8-inch relief sewer in Bechelli Lane between Wilshire Drive and
Beagle Lane.
PURPOSE OF PROJECT:
To increase the pumping capacity of Lift Station No. 2 and to bypass the
discharge from the Eastside Interceptor to the westside interceptor via
the Bechelli Ler.e gravity trunk line sewer. The primary purpose of this
;project was to eliminate raw sewage overflows that occurred a result
of inadequate pumping capacity of lift station and inadequate gravity
trunk capacity on both Bechelli Lane and Ricardo Avenue. As indicated
in the 7979 Master Sewer Plan, peak wet weather flows were 190 percent
of the effective pumping capacity of Lift Station No. 2 and sewage
overflows had occurred on a regular basis along Ricardo Avenue and
Bechelli Lane. The 1979 Master Sewer Plan recommended construction: of
the Golf Drive Lift Station and elimination of Lift Station No. 2. In
addition, the plan recommended construction of a new gravity trunk line
in Bechelli Lane that would discharge into the Bonnyview Interceptor and
construction of an 8-inch relief sewer in Bechelli Lane between Wilshire
Drive and Eeagle Lane . Because of limited funds and property
acquisition problems, the Golf Drive Lift Station was not constructed.
City Public Works staff instead recommended an interim solution of
upgrading Lift Station No. 2 and the construction of a gravity trunk
line and relief sewer in Bechelli Lane as originally proposed 111 the
1979 Master Sewer Plan. Modifications of Lift Station No. 2 included
construction of a new force main, new variable speed control system, new
standby generators, electrical panels, and a new building. The gravity
sewer trunk line and force main in Bechelli Lane were completed in
November 1980. The 8-inch relief sewer in Bechelli Lane was completed
in May 1980. The lift station modifications were completed en
January 19, 1982 except for the replacement of the pumps and motors.
Replacement of the existing motors and pumps with larger units will be
completed in 1953-84 .

HIATT DRIVE LIFT STATION BYPASS
BENEFIT ZONE:
Subareas T-3, T-4 , and T-21 which are tributary to the old Hiatt Drive
Lift Station as depicted on the attached map and shown in the 1979
Master Sewer Plan.
DESCRIPTION OF PROJECT:
Construction of a 3,400 LF of . 8- and 10-inch gravity trunk sewer line to
the south down Boulder Creek bypassing the existing Hiatt Drive Lift.
Station.
PURPOSE OF PROJECT:
Construction of the gravity sewer trunk line bypass allowed the abandon-
ment of the Hiatt Drive Lift Station and removal of its discharge from
an .overloaded 6-inch sewer line downs`rean of the lift station. As
indicated in the 1979 Master Sever Plan, the Hiatt Drive Lift Station
was only at about 70 percent of its effective capacity. However,
section of 6-inch sewer main downstream from the lift station was
overloaded and heavily surcharged under 1979 peak flow conditions . The
1979 Master Sewer Plan recommended the most cost effective solution was
to construct a gravity sewer line bypass around the lift station. This
project was completed by the City in fiscal year 1981-82.
