The project also includes miscellaneous sidewalk and concrete curb and gutter replacement at various
locations throughout the city. Approximately 2,000 feet of trails is proposed to be resurfaced along
the Highway 5 corridor and in the Stone Creek neighborhood.
The feasibility report was prepared by the Engineering Dept. staff. It is estimated the City will save
between $85,000 and $100,000 with feasibility report preparation, design and construction
observation not being outsourced.
The trail and parking lot improvements (Project Area #4 and #5, respectively) were not included in
the feasibility report since the cost of these improvements will not be assessed.
A copy of the feasibility report is available in the Engineering Department.

The bolts to some gate and hydrant valves should be replaced at this time. It's thought some of these

area is all multi - family units.
