Jefferson City Zoning Code
CHAPTER 12
82 DRAINAGE AND GRADING PERMITS
§ 12.82.010 Purpose.
The intent of this chapter is to protect existing structures, development, and drainage patterns from negative effects of new development blocking or otherwise interfering with existing drainage patterns.
(Ord. 652 § 1, 2004)
§ 12.82.020 Drainage permit required.
A.
A Drainage Permit must be obtained prior to issuing any building permit for a new structure.
B.
A Drainage Permit must be obtained prior to installing any drainage pipe or constructing any drainage ditch that would discharge water outside the property on which the pipe or ditch is constructed.
C.
A Drainage Permit must be obtained prior to grading or paving (asphalt, concrete or any other impervious surface) that would change drainage patterns beyond the property on which the grading or paving occurs.
(Ord. 652 § 1, 2004)
§ 12.82.030 Grading permit required.
The City of Jefferson hereby adopts the optional Appendix Chapter 33 of the 1997 Uniform Building Code as adopted by the State of Oregon. The requirement for a Grading Permit contained in Appendix Chapter 33 is separate from the requirement for a Drainage Permit contained in this chapter, and both permits may be required for a single project.
(Ord. 652 § 1, 2004)
§ 12.82.040 Violations.
A.
If drainage or grading work for which a permit is required is performed without a permit, then the work constitutes a violation of the Development Code and a public nuisance. The violation of the Development Code may be subject to enforcement action as provided in Chapter 12.10. The public nuisance may be abated as provided in Chapter 5.04.
B.
If drainage or grading work for which a permit was issued is performed not in compliance with the approved plans then the work constitutes a violation of the Development Code and a public nuisance. The violation of the Development Code may be subject to enforcement action as provided in Chapter 12.10. The public nuisance may be abated as provided in Chapter 5.04.
