Whenever a developer is or has been required, as a condition of approval of a development permit, to construct a public facility which is the subject of this chapter, and which facility is determined by the city to have supplemental size, length or capacity over that needed for the impact of that development, and when such construction is necessary to ensure efficient and timely construction of the facilities network, a reimbursement agreement with the developer and a credit against the fee, which would otherwise be charged pursuant to this chapter on the development project, shall be offered. The reimbursement amount shall not include the portion of the improvement needed to provide services or mitigate the need for the facility or the burdens created by the development. The specific procedures for reimbursements and credits shall be adopted by resolution of the city council, with this chapter being considered as enabling and directive. (Ord. 50 § 11, 1990)
