Stormwater runoff or drainage shall be controlled and contained on site except where adequate off-site stormwater drainage systems are available. Stormwater runoff and/or drainage resulting from the manufactured home park must be controlled so that water will not flow onto a public sidewalk or onto adjacent property except when water flows in a natural course from one property to another. Drainage into a city street gutter must be approved by the city engineer. Manufactured home parks shall provide for on-site or off-site detention or control of excess stormwater or drainage resulting from the use. The manufactured home park shall not cause downstream property owners to receive stormwater runoff at a higher peak flow than would have resulted from the same event had the use or improvement not been present. (Ord. 444 § 1, 2011)
