Crane's pond elevated crosswalk would be expensive

I prefer painting the crosswalk. If we elevate the crosswalk, as some suggest, it would cost the following.
Supervisor Feiner and Town Council,
In follow up to the work session Tuesday, I again reviewed the project costs submitted by the lowest bidder.  While the overall bid is $92,304 the itemized units relating to the sidewalk in the park add up to about $25,000, work related to the speed table / crosswalk is about $38,000 and the portion to address drainage concerns associated with the crosswalk construction is about $ 29,000.
If the Town desires to paint a crosswalk and only implement the park improvements - handicapped curb cuts and a walkway from Edgemont Road to join with the existing pathway at the pond, it is necessary to re-bid the project as it is too great a change in scope from the original bid.
Please advise the direction you feel appropriate and I will than move forward.
Thanks,
Victor G. Carosi, P.E.
Commissioner of Public Works
Town of Greenburgh
