III. REASONS FOR RECOMMENDATION/BACKGROUND
On August 1, 1985 the Flood Control District executed a
Consulting Services Agreement with Integrated Design Services for
structural evaluation of several hillside buildings adjacent to
the San Ramon Bypass Channel project north of Mt. Diablo
Boulevard in Walnut Creek. The scope of the contract included
visual inspection before and after the Corp' s construction
project. The Corps commenced work on phase one of the channel,
north of Mt. Diablo, in March 1986, but terminated the contract
before completion due to disputes with their construction
contractor. The work remained unfinished during the second phase
of the project. It will be completed as part of Phase 3 in 1991.
Since considerable time has lapsed since initiation of work, a
structural evaluation was conducted prior to the start of Phase
3 . This will allow structural problems resulting from the 3rd
phase of work to be more clearly distinguished from those of the
1st Phase. In order to fully evaluate construction impacts it
will be necessary to conduct a final structural survey at the
conclusion of the Phase 3 project. Thus the original consulting
services agreement must be amended to provide for a third
structural evaluation. The consultant has estimated the cost of
the additional work to be $6, 000. 00
IV. CONSEQUENCES OF NEGATIVE ACTION
Without a final structural evaluation, a complete documentation
of project impacts will be unavailable.
