State and sponsor’s share of cost
Wis. Stat. § 114.34
in effect(1) The costs of airport improvement projects involving federal aid, in excess of the federal government’s share, shall be borne by the sponsor and the state, except that the state shall pay not more than one-half of the excess costs, nor more than $1,250,000 for the cost of a building project or building improvement project and no part of the cost of hangars. The secretary, upon agreement with the sponsor, may advance up to 10 percent of the amount of any federal aid grant agreement for the payment of project costs of a federal aid project from unallocated state airport funds, subject to reimbursement upon final liquidation and settlement of the project with the sponsor and federal government.
(2) The costs of projects not involving federal aid shall be borne by the sponsor and the state. The state shall pay not more than 80 percent of the costs, which may include the cost of the land, the cost of lands or interest in lands deemed necessary for the protection of the aerial approaches, the cost of formulating the project application and preparing the plans and specifications, and the cost of construction and of all facilities deemed necessary for the operation of the airport. The state shall not contribute more than $1,250,000 for the cost of a building project or building improvement project and no part of the cost of hangars.
(3) The percentage of the costs borne by the state shall be determined by the department on the basis of the relative importance of the specific project to the state airport development program as a whole.
