1. Preparation and approval of plans shall be carried out within the following regulations:
(1) An authority shall not acquire real property for a project unless the governing body of the city has approved the plan, as prescribed in subdivision (9) of this section.
(2) An authority shall not prepare a plan for a project area unless the governing body of the city has declared, by resolution or ordinance, the area to be blighted, insanitary or undeveloped industrial area in need of industrial development.
(3) An authority shall not recommend a plan to the governing body of the city until a general plan for the development of the city has been prepared.
(4) The authority itself may prepare or cause to be prepared a plan or any person or agency, public or private, may submit such a plan to an authority. A plan shall be sufficiently complete to indicate its relationship to definite local objectives as to appropriate land uses, improved traffic, foster employment, public transportation, public utilities, recreational and community facilities and other public improvements and the proposed land uses and building requirements in the project area, and shall include without being limited to:
(a) The boundaries of the project area, with a map showing the existing uses and condition of the real property therein;
(b) A land use plan showing proposed uses of the area;
(c) Information showing the standards of population densities, unemployment within area and adjacent areas, land coverage and building intensities in the area after completion of the plan;
(d) A statement of the proposed changes, if any, in zoning ordinances or maps, street layouts, street levels or grades, building codes and ordinances;
(e) A statement as to the kind and number of additional public facilities or utilities which will be required in the area after completion of the plan;
(f) A schedule indicating the estimated length of time needed for completion of each phase of the plan.
(5) Prior to recommending a plan to the governing body for approval, an authority shall submit the plan to the planning agency, if any, of the community in which the project area is located for review and recommendations as to its conformity with the general plan for the development of the city as a whole. The planning agency shall submit its written recommendations with respect to the proposed plan to the authority within thirty days after receipt of the plan for review. Upon receipt of the recommendations of the planning agency, or, if no recommendations are received within the thirty days, then without the recommendations, an authority may recommend the plan to the governing body of the city for approval.
(6) Prior to recommending a plan to the governing body for approval, an authority shall consider whether the proposed land uses and building requirements in the project area are designed with the general purpose of accomplishing, in conformance with the general plan, a coordinated, adjusted and harmonious development of the city and its environs which, in accordance with present and future needs, will promote health, safety, morals, order, convenience, prosperity and the general welfare, as well as efficiency and economy in the process of development; including, among other things, adequate provision for traffic, vehicular parking, the promotion of safety from fire, panic and other dangers, adequate provision for light and air, the promotion of the healthful and convenient distribution of population, employment opportunities, the provision of adequate transportation, water, sewerage and other public utilities, schools, parks, recreational and community facilities and other public requirements, the promotion of sound design and arrangement, the wise and efficient expenditure of public funds, the prevention of the recurrence of insanitary areas, conditions of blight or deterioration or undeveloped industrial or commercial use.
(7) The recommendation of a plan by an authority to the governing body shall be accompanied by the recommendations, if any, of the planning commission concerning the plan; a statement of the proposed method and estimated cost of the acquisition and preparation for the project area and the estimated proceeds or revenues from its disposal to industrial developers; a statement of the proposed method of financing the project; a statement of a feasible method proposed for the relocation of families to be displaced from the project area; and a schedule indicating the estimated length of time needed for completion of each phase of the plan.
(8) The governing body of the community may hold a public hearing on any plan or substantial modification thereof recommended by the authority, after public notice thereof by publication in a newspaper of general circulation in the community once each week for two consecutive weeks, the last publication to be at least ten days prior to the date set for hearing. The notice shall describe the time, date, place and purpose of the hearing and shall also generally identify the area to be covered by the plan. All interested parties shall be afforded at the public hearing a reasonable opportunity to express their views respecting the proposed plan.
(9) Following the hearing, the governing body may approve a plan if it finds that the plan is feasible and in conformity with the general plan for the development of the community as a whole. A plan which has not been approved by the governing body when recommended by the authority may be recommended again to it with any modifications deemed advisable.
(10) A plan may be modified at any time by the authority, or by the governing body; provided that, if modified after the lease or sale of real property in the project area, the modification must be consented to by the industrial developer of the real property or his successor, or their successors in interest affected by the proposed modification. Where the proposed modification will substantially change the plan as previously approved by the governing body, the modification must similarly be approved by the governing body.
2. As an alternative to the procedures prescribed in subdivisions (2) and (5) of subsection 1, an authority may find an area to be a blighted or insanitary or undeveloped industrial area and in need of industrial or commercial development and may simultaneously prepare a plan and recommend to the governing body of the community the approval of such finding of * a blighted or insanitary or undeveloped industrial area and the approval of a plan, whether prepared by the authority or submitted to the authority, and the governing body may make its finding and approve the plan simultaneously. Simultaneously with such recommendation of a finding of a blighted or insanitary or undeveloped industrial area and recommendation of a plan to the governing body for approval, an authority shall submit the finding of a blighted or insanitary or undeveloped area and the plan to the planning agency, if any, of the community in which the project area is located for review and recommendation as to the conformity of the plan to the general plan for the development of the community as a whole. The planning agency shall submit its written recommendations with respect to the finding of a blighted or insanitary or undeveloped industrial area and the plan to the authority and the local governing body within thirty days after receipt of the findings and the plan for review. Upon receipt of the recommendations of the planning agency, or, if no recommendations are received within the thirty days, then without the recommendations, the governing body may approve the finding of a blighted or insanitary or undeveloped industrial area and may approve the plan in the manner prescribed in subdivisions (8) and (9) of subsection 1.
