Proposal for Services
I
INTRODUCTION
This proposal describes services to write a work plan, design structures, inspect construction
and write a construction report, for repairs and installation of closure drainage structures at the
toe of the Redding Benton Landfill.
The proposed work will be performed in conformance with the Cleanup and Abatement Order
(Order) from the Regional Water Quality Control Board, dated April 28, 1993 (Attachment C).
The Order requires that a plan must be submitted to the Regional Board by May 30, 1993,
describing how the City intends to upgrade current leachate and storm-water conveyance
systems.
In discussions with the Regional Board, the following tasks have been identified to meet the
requirements of the Order. It is assumed that these items will be addressed in the work plan in
a conceptual manner so that the Regional Board and City may request changes prior to formal
design.
The scope of work for design, inspection, and the construction report are described following
the tasks.
TASKS
(1) Eliminate runoff from greenwaste area from entering leachate system
It will be the responsibility of the City to determine the most appropriate means to eliminate
runoff from the greenwaste area. Lawrence & Associates will provide assistance, as needed,
on a time and expense basis to help make this determination.
i _
- Ms. Sue Hanson Attachment A
City of Redding May 12, 1993
Page 2 of 16
If the City chooses to install a retention pond by the greenwaste area, Lawrence & Associates
will determine the total runoff for the area provided by the City, for a 100-year 24-hour storm
event.
The option chosen by the City will be drafted onto a site map and shown as part of the storm-
water runoff improvements in the work plan submitted to the Regional Board.
(2) Shorten or remove laterals beneath the floor of the pond at the toe of
the landfill
Two leachate-collection laterals extend outward from the manhole at the toe of the landfill
(Figure Al and Figure A3, photos 9 and 10). A dual purpose of the laterals is to drain
residual water out of the pond. However, on March 23, 1993 the leachate collection system
backed-up creating pressure within the laterals. The hydraulic pressure on the north end of the
northern lateral caused piping in the soil beneath the containment berm. As a result, the fines
were washed out of the soil beneath the berm creating a conduit for migration of leachate into
Linden Creek. Although the point of leakage was temporarily patched, runoff next winter will
likely wash the patch away allowing stream water to enter the leachate collection system, or
allow leachate to leave the system into the Creek (depending on the relative water levels).
Lawrence & Associates will describe in the work plan and preliminary design how the laterals
will be excavated and inspected and the decision process for deciding whether to shorten or
remove the laterals and then how to backfill the trench to prevent further piping. Lawrence and
Associates will also incorporate repair of the containment berm into the erosion repair and
energy dissipator pool construction as described in tasks below.
Lawrence & Associates will provide inspection of the excavation to determine whether to
remove or shorten the leachate-collection pipes.

' (3 and 4 ) Repair damaged embankment and excavate and replace remaining
embankment
Piping caused by leach pipes, along with erosion from the stream channel along the
b embankment face (Figure A2, photos 4 and 5), has damaged the embankment around the pond
to the degree that its integrity for holding water and resistance to failure have been
compromised. Therefore, the affected portions of the embankment must be removed down to
native soil and replaced with properly compacted soil.
The drainage along the south side of the landfill up to Starlight Drive, has downcut between
the pond embankment and the bank of native soil to the south creating a vertical-walled gully
approximately 10 feet deep by 8 feet wide (Figures Al and A2, photo 8). This is due primarily
to the drainage channel being undersize to accommodate the recent storm event. The
embankment for the pond has been undercut and is susceptible to failure.
In a letter from Mr. Clayton Coles of Lawrence & Associates to Mr. Ron Masin ale of the
Yt g
City of Redding, item 4 recommended testing of the undamaged portions of the embankment to
assure it meets compaction requirements. A subsequent inspection of the soil indicates that is
contains far too much rock to test by a neutron densimeter and is poorly suited for testing by
the sand-cone method. The original construction of the pond is composed primarily of cobbles
and is not competent material for the existing embankment construction. Coupled with the
need to excavate for the removal of leachate-collection pipes, this embankment should be
removed to native soil and replaced with properly compacted material.
Lawrence & Associates will develop a final configuration for the re-built pond based on
volume requirements for collecting runoff. The final configuration will be developed to
maximize volume and minimize erosion. The conceptual design along with volume and flow
calculations, and embankment excavation and construction requirements will be presented in
the work plan.

City of Redding May 12, 1993

(5) Provide for adequate spillway
The spillway overflow pipes from the containment pond are inadequate to carry expected flows
from a 100-year event (Figure Al and Figure A3, photos 6 and 7). Re-sizing and design of
this over-flow will be incorporated into the repair of the drainage structure and energy
dissipator as described in the tasks below.
(6) Reconfigure manhole inlet to allow a maximum of 0.7 mg/d
A concern of the sewer department has been that the 0.7 million-gallons-per-day (mg/d)
capacity of the sewer line down Linden Canyon will be exceeded, therefore, a restrictor valve
was installed on the sewer line. During the March 23 storm, the sewer line became clogged at
the restrictor valve causing leachate to back up into the leachate-collection system, leading to
the failure of the system. To prevent this occurrence in the future, the restrictor valve must
be left open and/or the entry of surface water into the system must be designed to be debris
free.
To accomplish this, it is recommended that the inlet to the system should be reconfigured to
allow a maximum of 0.7 mg/d minus the maximum expected flow of leachate. This would be
done by sizing the inlet pipe to allow a regulated flow. The configuration would also require a
trash rack to minimize clogging.
Lawrence & Associates will proved a design for this system in the work plan.
I
(7) Replace the culvert along the north edge of the toe of the landfill to Closure
standards
The culvert which drains Linden Creek along the north side of the toe of the landfill is of
insufficient capacity for a 100-year storm event, as was demonstrated during the March 23
storm when the inlet was overtopped and severe gully erosion occurred on both sides of the
culvert completely exposing the culvert along part of its reach. (Figure Al and Figure A2,
photos 1 through 3). Th prevent this from occurring again, it is recommended that the
drainage be upgraded to closure-regulation standards.

j
Ms. Sue Hanson Attachment A
City of Redding May 12, 1993
Page 5 of 16
The closure plan had originally included leaving the existing 36-inch culvert in place and
adding a concrete overflow channel. However, because the soil was washed away from the
culvert and was subsequently replaced with uncompacted fill, the adequacy to withstand further
erosion has been reduced. This was demonstrated by a flow of several gallons per minute
(May 7, 1993) which entered the culvert but did not exit the bottom of the culvert, which
would indicate some degree of piping is occurring around the pipe.
Failure of the culvert would most likely result in failure of the proposed adjacent overflow
channel because of an inadequate foundation for the overflow channel; therefore, either the
existing culvert must be removed and replaced using proper construction practices, and then
the proposed overflow channel be installed, or preferably, the existing culvert be removed and
replaced with a larger culvert(s).
Because the existing culvert must be removed in any case, it is recommended that a larger pipe
be installed and the spillway eliminated. The larger culvert would be placed north of the
existing culvert in undisturbed native soil. Lawrence & Associates will provide a conceptual
design in the work plan. Preliminary and final design will be performed after approval of the
work plan.
DESIGN
Design will include the following tasks:
A. Prepare preliminary survey for topography and construction control
Because the culvert area has been regraded, the existing topographic maps are not adequate for
design of construction, Lawrence & Associates will provide a revised topographic survey of
the culvert area. The survey coverage will include (1) channel and headworks at the crest of
landfill, (2) profile and cross-sections along proposed location of new drainage, (3)
topographic data of lower containment pond and embankment, and (4) locations of all
improvements such as wells, sewer lines and improvements.

B. Prepare preliminary design for storm damage repair
(1) Perform calculations for sizing of drainage structures and facilities along the
north and south sides of the landfill from the crest of the landfill to the natural
drainage to the east of the pond, and the energy-dissipation pool at the base of
the fill in the natural channel.
(2) Prepare project overview and plan and profile drawings of proposed design for
City of Redding and RWQCB review.
(3) Provide typical sections of proposed drainage facilities and lower pond levee
repair.
(4) Provide preliminary engineer's estimate for project construction.
C. Meet with the City of Redding and RWQCB officials to review preliminary design
(1) Incorporate changes agreed to by the City and RWQCB.
(2) Reach concurrence on design concepts and proposal for final design, and items
of work to be included in the current construction contract.
D. Complete construction drawings and specifications
(1) Provide approximately 6 sheets of construction drawings, including plan and
profile sheets of drainage facilities, headwall and energy dissipator details,
typical cross-sections of drainage and embankment construction details, and
final grading plan.
(2) Prepare quantity calculations and engineer's estimate for total project under this
proposal and those items to be included in the first phase of construction.
