(1)    Contracts between authority and city. In connection with any housing project located wholly or partly within the area in which it is authorized to act, any city may agree with an authority or government that a certain sum, subject to the limitations imposed by s. 66.1201 (22), or no sum shall be paid by the authority in lieu of taxes for any year or period of years.

   (2)   Advances to housing authority. When any housing authority created for any city is authorized to transact business and exercise its powers, the governing body of the city may immediately make an estimate of the amount of money necessary for the administrative expenses and overhead of the housing authority during the first year after the creation of the housing authority, and may appropriate the amount to the authority out of any moneys in the city treasury not appropriated to some other purposes. The moneys appropriated may be paid to the authority as a donation. Any city, town, or village located in whole or in part within the area of operation of a housing authority may lend or donate money to the authority. The housing authority, when it has money available to repay loans made under this subsection, shall make reimbursements for all loans made to it.

   (3)   Project submitted to planning commission. Before any housing project of the character designated in s. 66.1201 (9) (a) is determined by the authority, or any real estate acquired or agreed to be acquired for the project or the construction of any of the buildings begins or any application made for federal loan or grant for the project, the extent of the project and the general features of the proposed layout indicating in a general way the proposed location of buildings and open spaces shall be submitted to the planning commission, if any, of the city or political subdivision in which the proposed project is located, for the advice of the planning commission on the proposed location, extent, and general features of the layout.

   (4)   Cooperation with cities, villages and counties. For the purpose of cooperating with and assisting cities, villages and counties, a housing authority may exercise its powers in that territory within the boundaries of any city, village or county not included in the area in which that housing authority is then authorized to function, or in any designated portion of that territory, after the governing body of the city, village or county adopts a resolution declaring that there is a need for the authority to function in the additional territory. If a housing authority has previously been authorized to exercise its powers in the additional territory or designated portion, a resolution shall not be adopted unless the housing authority finds that ultimate economy would be promoted, and the housing authority shall not initiate any housing project in the additional territory or designated portion before the adoption of the resolution.

   (6)   Controlling statutes. Insofar as ss. 66.1201 to 66.1211 are inconsistent with any other law, the provisions of ss. 66.1201 to 66.1211 control.

   (7)   Supplemental nature of statute. The powers conferred by ss. 66.1201 to 66.1211 are in addition to the powers conferred by any other law.
