SUBJECT: WATER REUSE PROJECT- AMENDMENT TO AGREEMENT FOR COON
CREEK MITIGATION
CAO RECOMMENDATION
1. Approve Amendment to Agreement with TRC in the amount of$6,600 for guard rail design
as related to Coon Creek steelhead passage restoration as mitigation for the Water Reuse
Project.
2. Approve an additional $3,400 contingency, to be administered by the Project Manager, for
possible project design changes.
DISCUSSION
As part of the Water Reuse Project mitigation, the City must offset project action effects on habitat
by acquiring and preserving in perpetuity instream habitat or creating instream habitat. Working
with the California Department of Fish and Game and PG&E, City staff identified the replacement
of plugged culverts on Coon Creek about a half-mile from the ocean as a mitigation measure which
would make approximately 5.6 miles of stream accessible to steelhead. The City awarded a design
contract with TRC in the amount of $120,000 on February 28, 2003. The most cost effective
solution for the stream crossing is a built in-place slab bridge.
As part of the bridge design, PG&E has expressed the desire for guard rails because the bridge will
be on the emergency egress route from the Diablo Canyon Power Plant and guard rails will help
ensure safe egress across the bridge in the event of an emergency. The area constraints and
topography of the bridge crossing will not accommodate the standard metal beam guard rail design.
The proposed scope of work is given in Exhibit A of Attachment 1. This design work was not
anticipated at the time of the original contract. This Amendment to the February 28, 2003 contract
with TRC will provide an additional $6,600 for guard rail design. Staff also recommends approval
of a$3,400 contingency, to be administered by the project manager,to address any additional minor
design changes in the project resulting from PG&E's review of the plans.
FISCAL IMPACT
Currently, $784,000 is in the budget for mitigation measures for the Water Reuse Project CIP.
There is an available balance of $386,000 in this account to support this project (FY 2001-2003
Financial Plan Appendix B,page 106).

.Request for Scope Amendment
Coon Creek Salmon Passage Restoration Project
Contract No. 99124.90557
Dear Ms. DiSimone:
As you know, TRC recently provided the City of San Luis Obispo staff with the 90%
design drawings completed for the Coon Creek salmon passage restoration project under
the referenced contract. In recent meetings with City staff,we have discussed the PG&E
requirement that guardrails be provided on the approaches to the bridge to be constructed
over Coon Creek in conjunction with the project. Even though the road is private and
normally has very low traffic and low travel speed,PG&E has expressed the desire for
the guard rails because the bridge will be on the emergency egress route from the Diablo
Canyon Power Plant, and the guard rails will help to ensure safe egress across the bridge
in the event of an emergency. As we have discussed with City staff, the area constraints
and topography at the bridge crossing will not accommodate the standard metal beam
guardrail design. Pursuant to our recent discussion,this letter is provided to request an
amendment to the contract to allow TRC to develop site-specific metal beam guard rail
designs for the bridge approaches.
The road configuration and topography at the bridge approaches will require a different
design at each of the four comers of the bridge. For the suggested contract amendment,
we propose the following work scope:
Task 1:
Plot out all four corners of the bridge plus 100 feet beyond at a workable scale. The plots
will incorporate the physical characteristics of the site,based on the original surveys
obtained.early in the project.
Task 2:
Layout 62'6" of standard guard rail at all four corners of the bridge and then modify as
appropriate to fit the site physical characteristics. Once the layout is satisfactory,
incorporate the appropriate details into our bridge plans, and call out the dimensions that
supersede the standard plans.

Task 3:
Assemble, compile, and edit the special provisions for the Metal Beam Guard Rail to
match the appropriate design.
Task 4:
Revise the quantities and estimate to include the Metal Beam Guard Rail.
Task 5:
Document the modifications to the standard layout for each comer in a letter format to be
presented to the City for filing.
We estimate that we could develop the metal beam guardrail design for all four comers of
the bridge with about two additional design sheets. Based on two additional design
sheets, we estimate the cost to complete the above tasks will be approximately$6,600.
As we discussed, it would be appropriate to allow a contingency in the event that more
than the estimated amount of work is required. We suggest the amendment to the
contract be developed for a cost not to exceed $10,000. This would allow up to about
four design sheets to be completed, if necessary. Work will be billed on a time-and-
materials not-to-exceed basis, according to the schedule of charges referenced in the
existing contract, so the City will be billed only for the effort actually incurred.
We are prepared to begin work on the guardrail designs promptly upon approval by the
City. We expect that the design could be completed in less than a month.
Please feel free to call me any time.
Very Truly Yours,
Joseph L. Stenger, R.G., R.E.A.
