If City Council wants to consider reducing the total cost even further here are a few items which could be eliminated: Item Eliminated Project Savings Bituminous Trail (Parking Lot to Crystal Avenue) $8,900.00 Basketball Half Court $11,175.00 Picnic Shelter(leave concrete pad for future $13,586.00-$16,677.00 installation) Picnic Tables, Benches, Trash Receptacles (purchase from State contract—City staff $2,250.00 installed) Construction Considerations The grading of the site, as has been discussed previously, will create a higher area on the west portion of the site on which the parking lot and amenities will be placed. The western perimeter will be graded to flow around to the rain garden so any drainage off of the adjacent rear yards will be properly dealt with. The higher area will be above the 100 year flood elevation of Lake Valentine. In fact, the elevation will be very near the low point on Old Highway 10 so if water ever got high enough to flood the amenities and parking lot it would also be overtopping Old Highway 10. Although the perimeter bituminous trails have been removed from the project, the site grading will prepare this area to be ready for a trail sometime in the future. Geotechnical investigation completed for the design of the project revealed up to 14 feet of organic soils on the site, the worse soils are located where the amenities are planned to be placed. The recommendation from the Soils Engineer includes a granular base and drain tile under the parking lot and amenities which are included in the bid. The Soils Engineer also recommends letting the parking lot and amenities area consolidate for a period of time after the additional fill is placed to create the higher area. Therefore, the bid has been set up to require the contractor to have the site fully graded and seeded by the end of June 2012. This would include gravel in the parking lot area and temporary seed in the amenities area. Then the site is to sit until spring of 2013 to allow for consolidation of soils. The remaining contractor work is required to be completed by the end of June 2013, at which time the items purchased from the State contract would be installed. This construction schedule, due to the soil condition, would have the park out of service for approximately one year, although the grass field area could be used as soon as reasonable turf is established.
