FISCAL IMPACT
This project will necessitate an appropriation of $214,500 from the Redevelopment Agency's South
Central Project Area Funds to Capital Improvement Project No. 700149. 'This appropriation request is
scheduled before the Tustin Community Redevelopment Agency at their meeting of July 7, 1998.
BACKGROUND
The City is currently under contract with Brongo Construction for the construction of storm drain
improvements along the northerly and southerly sides of Sycamore Avenue, and construction of a block
wall along the southerly side of Sycamore Avenue between Newport Avenue and the SR-55 Freeway.
Once the storm drain and block wall construction is complete, the southerly side of Sycamore Avenue will
be landscaped in conjunction with the East Tustin RehabilitationProject.
In preparation for the installation of the storm drain line on the north side of Sycamore Avenue all the
existing vegetation was removed exposing a chain link fence and the adjacent properties. Subsequently,
requests were received to complete this entryway to our City by constructing a matching block wall and
landscaping on the north side. In an effort to reduce the cost of construction and eliminate the need to
award a new construction contract, staff proceeded'with the design of the northerly wall in anticipation of
being able to utilize the existing contractor through a change order or a supplemental agreement.
However, during the design process it was determined that the wall construction will require the relocation
of an existing 8" water main and the installation of a localized drainage system on adjacent private property
due to conflicts with the wall footing and the blocking of existing drainage patterns. As a result the most
recent estimate of probable cost for the improvements is:
ESTIMATED COST
Cleating and Grubbing ...................................................................... $10,000
Construction of Block Wall ............................................................... $ 90,000
Relocate 8" Water Main .................................................................... $ 40,000
Engineering (Design and Construction) ............................................ $15,000
Landscaping/Irrigation ..................................................................... $ 40,000
Subtotal $195,000
1.0% contingency $ 19,500
Total $214,500
Additionally, the existing sidewalk along the north side will be replaced as part of the wall construction.
Funding for this portion of construction (estimated at $12,500) is proposed in the FY98-99 Annual
Sidewalk Replacement Program.
