Town Funding

Town Staff, working with the Town Board were able to work with ELQ Industries to scale back the project in regards to the extent of the geographic area of the streetscape improvements as well as scaling back specific types of streetscape details, including the elimination of the irrigation system for the streetscape trees and plantings, in order to reduce the estimated project cost to $11.6 million. The Town of New Castle has committed to funding the $11.6 million project through various sources of money (sewer and water fund balance) and through the issuance of bonds to ensure that the project can be completed.
