(a) Storm water retention and detention basins are required by the City development and engineering standards. City policy encourages the perpetual ownership and maintenance of such facilities by property owners or by groups of property owners acting together in an association. Sometimes such ownership is not practical or cannot be accomplished.
(b) In order to qualify for perpetual maintenance of a detention basin by the City, the property owner who is responsible for building the basin must build it as a non-flow-through type detention basin.
(c) Exhibit A, below, illustrates a typical profile of such a basin. In addition, the property owner must pay to the City a fee of three thousand five hundred dollars ($3,500) per acre or portion thereof, payable prior to the construction of the basin (measured from A to B on the Exhibit). There is a minimum fee of seven thousand dollars ($7,000). This fee shall be deposited by the Finance Director and interest only as needed shall be transferred to the Street Department budget to pay for the cost of an estimated eight mowings and one sewer jetting per year, as well as the cost of insurance and other incidental expenses.
(d) It is intended that such detention basins will provide passive park areas. They are to be relatively flat, generally dry when not flooded, and have durable and sufficient grass cover. The City Engineer is required to approve grasses, grading, slopes, installation of all drainage systems, and the adequate growth of all ground cover before accepting the project. A fee simple deed to the detention area shall be granted to the City at the time of acceptance of the project. When the City Engineer determines that it is necessary, the deed shall also provide a permanent access easement twenty feet in width.
