BACKGROUND
Effective September 11, 2012, the Local Agency Formation Commission of the County of Los
Angeles approved the annexation of Vista Canyon through City of Santa Clarita (City)
Annexation No. 2011-20. Consistent with the Vista Canyon Specific Plan and in accordance with
the California Environmental Quality Act, the City is the lead agency for this development and is
required to administer the requirements contained in the Environmental Impact Report. Included
therein are provisions for soil cement bank stabilization on the banks of the river corridor, bulk
grading, and the import of up to 500,000 cubic yards of soil. This is also consistent with the
primary objectives of the Vista Canyon Specific Plan's drainage concept and stormwater
management program.
Due to the unique character of the work being performed on this project, the services of afull-

time inspector are necessary to oversee the bulk grading and the dirt hauling associated with bulk
grading and future Lost Canyon Road grading. Additionally, with the anticipated El Nino
weather pattern predicted through April, it is important to have an inspector onsite to ensure
compliance with site-specific Storm Water Pollution Prevention Plan and Best Management
Practices.
California Government Code 4526 prescribes the selection of architectural and engineering
services to be based on demonstrated competence and professional qualifications necessary for
the satisfactory performance of the services required and does not authorize the selection of
professional architect and engineering services based on cost. Therefore, and based on their
previous experience on similar City projects and their illustrated understanding of the needs of
this project, staff recommends the City Council award the contract for inspection services to
Tetra Tech, Inc., for this project. In addition to their professional qualifications, City staff was
able to reach an agreement with Tetra Tech, Inc., at a fair and reasonable price.
This item authorizes a professional services contract in the amount of $84,000 and authorizes a
contingency in the amount of $8,400 for a total contract amount not to exceed $92,400. The
amount of $92,400 will also be reimbursed by the developer.

Other action as determined by City Council.
FISCAL IMPACT
The total amount of this agreement will not exceed $92,400. Upon approval of the recommended
action, the budget will be adjusted accordingly.
