(a) When consideration is given by the proprietor to the allocation of areas suitably located and of adequate size for playgrounds, school sites, parks and recreation facilities, as indicated in the comprehensive development plan and the zoning ordinance, such areas shall be provided by one of the following methods:
(1) Dedication to the city.
(2) Reservation of land for the use by property owners by deed or covenants.
(3) Reservation for acquisition by the city or school board within a period of two years. This reservation shall be made in such a manner as to provide for a release of the land to the proprietor if the city or school board does not proceed with the purchase within the prescribed time limit.
(b) Due regard shall be shown by the planning commission and the city council for preserving outstanding natural features such as scenic spots, watercourses, or stands of trees. Every effort shall be made by the proprietor to preserve any nondiseased tree whose trunk is five inches in diameter or more, regardless of its location within the plat.
