SUBJECT: ADDENDUM TO THE CONTRACT FOR PHASE II OF THE
STORMWATER MASTER PLAN
DEPARTMENT: Building & Engineering Services
:� .'• Jam:
On December 12, 1995, City Council approved a contract for Phase II of the Stormwater Master
Plan (SMP). The original contract was approved in the amount of $399,133. The original scope
of work and cost estimate submitted by the consultant were significantly reduced by more than
$230,000 by City staff in the preparation of the contract for Phase II.
It has now been determined that some additional services recommended in the original scope
of work will be necessary during Phase II to better complete that portion of the SMP contract.
The addendum covers the costs of consultant services for management and coordination of all
portions of the work to ensure that all elements of the SMP, automated mapping system and
hydraulic modeling are compatibly designed and will successfully integrate when completed.
It is essential that this coordination occur during the design and set-up of the database and
mapping system.
This item recommends approval of the addendum to the contract for Phase II of the SMP and
automated mapping in the amount of $24,300. This is a six percent increase to the existing
SMP contract. These costs were anticipated when the Stormwater Utility was established and
were included in the three-year Utility start-up budget.

City Council direct the City Manager to execute an addendum to the contract in the amount of
$24,300 with Woodward -Clyde Consultants, and authorize the transfer of $24,300 from the
Stormwater Utility fund balance Account No. 51-2600 to Account No. 51-5602-227.
