  § 18.70.510. Retention/detention.  

Latest version.

  • A.

    A residential subdivision-wide stormwater management plan that has a retention/detention area will be maintained by the developer, or is successors-in-interest, for a minimum period of one year from the completed construction of the retention/detention area. Any necessary repairs to the control area will be completed prior to the acceptance by the city.

    B.

    A commercial subdivision stormwater management retention/detention area will be permanently maintained by the developer, or its successor-in-interest. Minimum standards established by this chapter shall be maintained at all times.

    C.

    For planned unit developments, retention/detention areas may be combined with open/recreational spaces as dual use. In the event dual use is approved as a part of the development plan, the total area designated for retention/detention of stormwater shall be maintained by the developer or homeowner's association referenced in Section 17.30.330, and the city shall not assume ownership or maintenance responsibility.

    D.

    All subdivision-wide stormwater management areas that will be maintained by the city shall be constructed without trees, shrubs or permanent structures that would interfere with maintenance requirements. The developer shall establish the retention/detention area with a native or drought resistant grass.

    E.

    The inside slope of a retention/detention area shall be no steeper than a five to one ratio (horizontal:vertical).

    F.

    The maximum depth of a retention/detention area will be two feet. The allowable depth shall be the vertical distance from grade level to the bottom of the retention/detention area.

    G.

    Upon the recommendation of the director of public works, the commission may approve a deviation in the size and depth of a retention/detention area if the location of the retention/detention area is placed away from the streets and lots in a manner that will maximize visual and esthetic features, reduce or minimize health and safety risks, and not adversely impact the maintenance of the retention/detention area.
