COUNCIL AGENDA REPORT ITEM
FROM: Michael D. McCluskey, Public Works Director
PREPARED BY: Morris D. Witbeck, Engineering Assistant
SUBJECT:
Bids for Four Creek Bank Stabilization Projects at Various Locations:
1. San Luis Creek at 236 Higuera St. , Specification 9556-520-553
2. San Luis Creek at 3046 S. Higuera, Specification 9555-520-553
3. San Luis Creek at 35 Prado Road, Specification 9554-520-553
4. San Luis Creek at 3546 S. Higuera, Specification 9553-520-553
CAO RECOMMENDATION:
A. Reject all bids.
B. Adopt the mitigated negative declaration and monitoring program for the
four creek repair projects.
DISCUSSION:
On September 5, 1995 the City Council: 1) Authorized staff to advertise
for bids; 2) Authorized the CAO to approve the plans upon completion of the
environmental process; and 3) Authorized the CAO to award each contract if
the lowest responsible bid was within the engineer's estimate, or to award
all contracts if the aggregate of the lowest responsible bids was within
the aggregate of the engineer's estimates for all four projects.
On September 26, 1995 bids were opened, the results of which are shown on
the attached bid summary sheet.
Unfortunately, the required permits and approvals from regulating agencies
were not received before the beginning of the rainy season, defined by
those agencies as October 15 or October 31, depending on the agency. Since
work in the creek is not allowed after those dates, the projects could not
proceed as planned.
The Corps staff expressed concern regarding the number of creek bank repair
projects when they were here in the spring looking at the flood damage.
Before issuing any more permits for bank projects that "harden" the bank,
they want a professional hydrologist to review the cumulative impacts of
past, the current and potential future projects. The need to provide this
report prior to permitting these four projects was not made clear to staff
until late September.
It is staff's intention to continue forward with these projects and
readvertise next spring upon obtaining the delayed permits and approvals.
Should design changes be mandated by those agencies, staff will revise the
plans and resubmit to Council next spring. After awarding a contract in
the spring, Public Works will issue a purchase order for the creek
landscaping (estimated at $5,000-$10, 000) required for environmental
mitigation.

COUNCIL AGENDA REPORT ITEM NUMBER:
FROM: Michael D. McCluskey, Public Works Director Np^�
PREPARED BY: Morris D. Witbeck, Engine ung Assistant
SUBJECT:
Four Bank Stabilization Projects at Various Locations:
1. San Luis Creek at 236 Higuera St. - Spec. No. 9556-524-553
2. San Luis Creek at 3046 S. Higuera St. - Spec. No. 9555-520-553
3. San Luis Creek at 35 Prado Road - Spec. No. 9554-520-553
4. San Luis Creek at 3546 S. Higuera St. - Spec. No. 9553-520-553
CAO RECOMaIENDATION:
By motion: 1) Authorize staff to advertise for bids; 2) Authorize the CAO to approve the
plans upon completion of the environmental process, and 3) Authorize the CAO to award
each contract if the lowest responsible bid is within the engineer's estimate, or to award
all contracts if the aggregate of the lowest responsible bids is within the aggregate of the
engineer's estimates for all four projects.
DISCUSSION:
Creek banks at several locations in San Luis Obispo have been eroding over the years. During
the storms of March of this year, erosion was accelerated to the point that immediate remedial
action is imperative to avoid losses to private property from next winter's storms.
In order to accomplish the work prior to the upcoming rainy season, the Council is being asked
to authorize advertising the project and delegation of project approval to the CAO after
completion of environmental documents. While staff is confident all environmental approvals
will be received, staff feels awaiting Council action until those approvals are received would add
between three and four weeks processing time. The procedure described for these projects is
only proposed due to the quickly approaching storm season.
Applications and notifications have been sent to all permitting agencies. A biologist has provided
the necessary information for an environmental determination. The environmental documents
are being circulated, and approval of plans and award of contracts cannot be considered until
that process is completed. If the environmental work identifies something unexpected and cannot
be easily incorporated, the projects may have to be deferred and not approved and awarded.
Mitigation measures identified by the biologist will closely follow in a separate contract after the
banks have been stabilized.
FISCAL EMPACT:
9556-520-553 Estimate $120,000
10% contingencies 12,000
9555-520-553 Estimate. 1202000
10% contingencies 12,000
9554-520-553 Estimate 125,000
10% contingencies 12,500
9553-520-553 Estimate 85,000
10% contingencies 8,500
TOTAL: $495,000
Estimated cost for
mitigation measures: $ 51000
It is anticipated that full reimbursement of project costs will come from the Federal Emergency
Management Agency (FEMA). Representatives from Public Works and Finance are working
closely with local FEMA representatives to ensure full compliance with FEMA regulations.
There is a possibility that projects or portions of projects at certain locations may be ineligible
for reimbursement. In these cases the City will have to cover the ineligible costs. Staff has
applied to Zone 9 for revenue to pay for possible ineligible costs. General Fund money will be
used as a last resort.
