(Ord. 08-O-610 § 6; Ord. 13-O-714 § 2)
No owner of property located within the corporate limits of the city of Brookings, or any other person, shall construct a storm drainage system, or excavate any ground for the purpose of construction of a storm drainage component thereon, without first having applied for and received from the city a development permit for such construction and excavation. A development permit from the city will not be granted without submittal of plans and a copy of permits or letter of non-interest from the Department of State Lands and Army Corps of Engineers, if required by law.

(Ord. 08-O-610 § 7; Ord. 13-O-714 § 2)
Any owner of property located within the corporate limits of the city of Brookings, or any other person desiring to construct or excavate for a storm drainage component within the corporate limits, must comply with the following procedure. An application in writing shall first be made to the public works department setting forth the description of the land upon which a storm drainage component is to be constructed and upon which the excavation, if any, is to be made. This application shall also set forth the material to be used in the construction together with a statement as to how the storm drainage component is to be established. This application may require plans drawn by an Oregon licensed civil engineer and must include a minimum easement width of 15 feet. The city will consider the application, and if the provisions of this chapter have been met, a permit will be issued to the applicant to construct and excavate to the extent that such excavation is necessary to accomplish the purpose applied for.
A public works permit is required per Chapter 12.45 BMC for any and all work in a public right-of-way, waterway or drainage course and may be terminated by order of the city for failure by the property owner to properly maintain the improved waterway and drainage appurtenances in a safe and workmanlike manner.
(Ord. 08-O-610 § 8; Ord. 13-O-714 § 2)
