Chapter 227 - City Planning and Zoning
Section 227.290 - Building setback lines established by city council; criteria.

(2) The council may consider, in enacting ordinances governing building setback lines, the site slope and tree cover of the land with regard to solar exposure. The council shall not restrict construction where site slope and tree cover make incident solar energy collection unfeasible, except an existing solar structure’s sun plane shall not be substantially impaired.
(3) The council may consider, in enacting ordinances governing building setback lines and maximum building height, the impact on available wind resources. The ordinances shall protect an existing wind energy system’s wind source to the extent feasible.
(4) The powers given in this section shall be so exercised as to preserve constitutional rights. [Amended by 1979 c.671 §4; 1981 c.590 §9]
