Notice of the hearing, describing the time, date, place and purpose of the hearing and generally identifying the project area, shall be published as a class 2 notice, under ch. 985

Following certification, no new construction may be authorized by any agencies, boards or commissions of the city, in the area, unless as authorized by the local legislative body, including substantial remodeling or conversion or rebuilding, enlargement or extension of major structural improvements on existing buildings, but not including ordinary maintenance or remodeling or changes necessary to continue the occupancy.

Real property in the project area shall be leased or sold at its fair value for uses in accordance with the redevelopment plan notwithstanding that the fair value may be less than the cost of acquiring and preparing the property for redevelopment. In determining the property's fair value, a city shall take into account and give consideration to the following:
The restrictions upon and covenants, conditions and obligations assumed by the purchaser or lessee, and the objectives of the redevelopment plan for the prevention of the recurrence of slum or blighted areas.
Any lease or sale under this subsection may be made without public bidding, but only after a public hearing by the planning commission upon the proposed lease or sale and its provisions. Notice of the hearing shall be published as a class 2 notice, under ch. 985
The terms of a lease or sale under this subsection shall be fixed by the planning commission and approved by the local legislative body. The instrument of lease may provide for renewals upon reappraisals and with rentals and other provisions adjusted to the reappraisals. Every lease or sale shall provide that the lessee or purchaser shall carry out the approved project area redevelopment plan or approved modifications and that no use may be made of any land or real property included in the lease or sale nor any building or structure erected which does not conform to the approved plan or approved modifications. In the instrument of lease or sale, the planning commission, with the approval of the local legislative body, may include other terms, conditions and provisions as in its judgment will provide reasonable assurance of the priority of the obligations of the lease or sale and of conformance to the plan over any other obligations of the lessee or purchaser and assurance of the financial and legal ability of the lessee or purchaser to carry out and conform to the plan and the terms and conditions of the lease or sale; and may include terms, conditions and specifications concerning buildings, improvements, subleases or tenancy, maintenance and management and any other matters as the planning commission, with the approval of the local legislative body, may impose or approve, including provisions whereby the obligations to carry out and conform to the project area plan shall run with the land.

The grantee, and the heirs, representatives, successors and assigns of the grantee, may not convey, lease or let the conveyed property or any part of the property, or erect or use any building or structure erected on the property free from obligation and requirement to conform to the approved project area redevelopment plan or approved modifications.
The planning commission may, with the approval of the local legislative body, demolish an existing structure or clear the area of any part of the structure, or may specify the demolition and clearance to be performed by a lessee or purchaser and the time schedule for the work. The planning commission, with the approval of the local legislative body, shall specify the time schedule and conditions for the construction of buildings and other improvements.
In order to facilitate the lease or sale of a project area or, if the lease or sale is of parts of an area, the city may include in the cost payable by it the cost of the construction of local streets and sidewalks within the area or of grading and other local public surface or subsurface facilities necessary for shaping the area as the site of the redevelopment of the area.

The housing authority shall formulate a feasible method for the temporary relocation of persons living in areas that are designated for clearance and redevelopment. The housing authority and the local legislative body shall assure that decent, safe and sanitary dwellings substantially equal in number to the number of substandard dwellings to be removed in carrying out the redevelopment are available, or will be provided, at rents or prices within the financial reach of the income groups displaced.
After the city has assembled and acquired the real property of the project area, it shall, as an aid in determining the rentals and other terms upon which it will lease or the price at which it will sell all or part of the area, place a use value upon each piece or tract of land within the area which, in accordance with the plan, is to be used for private uses or for low-rent housing. The use value shall be based on the planned use and, for the purposes of this use valuation, the city shall provide a use valuation appraisal prepared by the local commissioner of assessments or assessor. Nothing contained in this section may be construed as requiring the city to base its rentals or selling prices upon the appraisal.
Before execution and delivery by the city of a lease or conveyance to a redevelopment company, or before consent by the city to an assignment or conveyance by a lessee or purchaser to a redevelopment company, the articles or certificate of incorporation or association or charter or other basic instrument of the company shall contain provisions defining, limiting and regulating the exercise of the powers of the company so that neither the company nor its stockholders, officers, directors, members, beneficiaries, bondholders or other creditors or other persons may amend the terms and conditions of the lease or the terms and conditions of the sale without the consent of the planning commission, together with the approval of the local legislative body, or, in relation to the project area development plan, without the approval of any proposed modification in accordance with sub.

A redevelopment corporation may be organized under the general corporation law of the state to be a redevelopment company under this section; may acquire and hold real property for the purposes set forth in this section; and may exercise all other powers granted to redevelopment companies in this section.
A redevelopment company, individual, limited liability company or partnership to which all or part of a project area is leased or sold under this section shall keep books of account of its operations of or transactions relating to the area entirely separate and distinct from accounts of and for any other project area or part of the other project area or any other real property or enterprise. No lien or other interest may be placed upon any real property in the area to secure any indebtedness or obligation of the redevelopment company, individual, limited liability company or partnership incurred for or in relation to any property or enterprise outside of the area.
Modification of development plans.
An approved project area redevelopment plan may be modified at any time after the lease or sale of all or part of the area if the modification is consented to by the lessee or purchaser, and if the proposed modification is adopted by the planning commission and submitted to the local legislative body and approved by it. Before approval, the local legislative body shall hold a public hearing on the proposed modification, notice of the time and place of which shall be given by mail sent at least 10 days prior to the hearing to the then owners of the real properties in the project area and of the real properties immediately adjoining or across the street from the project area. The local legislative body may refer back to the planning commission any project area redevelopment plan, project area boundaries or modification submitted to it, together with its recommendation for changes in the plan, boundaries or modification and, if recommended changes are adopted by the planning commission and formally approved by the local legislative body, the plan, boundaries or modification as changed becomes the approved plan, boundaries or modification.
Limitation upon tax exemption.
Nothing contained in this section may be construed to authorize or require the exemption of any real property from taxation, except real property sold, leased or granted to and acquired by a public housing authority.
