Developer had an option to purchase a five-acre parcel named The Highlands in City from Owner, and was planning to build a residential development there. Developer could not proceed with the project until City approved the extension of utilities to The Highlands parcel. In order to encourage development, City had a well-known and long-standing policy of reimbursing developers for the cost of installing utilities in new areas.

Developer signed a contract with Builder for the construction of ten single-family homes on The Highlands parcel. The contract provided in section 14(d), “All obligations under this agreement are conditioned on approval by City of all necessary utility extensions.” During precontract negotiations, Developer specifically informed Builder that he could not proceed with the project unless City followed its usual policy of reimbursing the developer for the installation of utilities, and Builder acknowledged that he understood such a condition to be implicit in section 14(d). The contract also provided, “This written contract is a complete and final statement of the agreement between the parties hereto.”
