It is hereby determined that unnecessary soil erosion necessitates costly repairs and maintenance of public works, reduces the clarity of public waters, increases the cost of providing pure drinking water and reduces the attractiveness and safety of water-oriented recreation facilities; that the public health, safety and welfare requires regulation of land balancing, development and construction activities to avoid unnecessary soil erosion; and that the regulations contained in this division are the minimum regulations which will avoid the consequences herein set forth and protect the public health, safety, and welfare.
(Ordinance 361 adopted 3/28/18)
No site or construction plan shall be approved unless it shows all improvements reasonably required to prevent erosion during and after completion of development. No permanent certificate of occupancy shall be issued unless the improvements shown on the site plan have been installed, constructed or created and erosion is effectively controlled.
(Ordinance 361 adopted 3/28/18)
No plat shall be approved unless it shows all improvements reasonably required to prevent erosion.
(Ordinance 361 adopted 3/28/18)
No permit shall be issued under this chapter unless the plans and specifications show and adequately describe all measures and improvements both temporary and permanent which can reasonably be undertaken to control and eliminate erosion during development, along with appropriate schedules based on time and stage of construction which show that such measures and improvements will be undertaken at the earliest practicable time, and show existing and proposed topographic information with two-foot contours.
(Ordinance 361 adopted 3/28/18)
No grading shall be undertaken prior to the issuance of an excavation or grading permit, site clearance permit, building permit, utility development permit or, under circumstances where no permit is required, prior to the issuance of the required permit by the city inspector. All permits are issued only pursuant to a written application containing the information required in this division.
(Ordinance 361 adopted 3/28/18)
No permit shall be required for horticultural activities, the construction of a driveway which does not at any point vary from the surrounding grade by more than five feet, the normal graveling or grading of a road or driveway, or any project where no permit is required under section 22.03.125.
(Ordinance 361 adopted 3/28/18)
(a) 
The drainage and erosion control design manual and the city’s Code of Ordinances contain requirements for the design of infrastructure related to erosion control facilities. Where there is any conflict between the drainage and erosion control design manual and the current city code, the more restrictive shall take precedence. The design engineer is responsible for complying with the latest version of the drainage and erosion control design manual and city code adopted by the city.
(b) 
The city inspector has the duty to impose any additional limits or restraints to prevent erosion after approval of any permit herein, whenever conditions arise during development of construction which require the taking of any additional measures or precautions.
(c) 
Where during development or construction, it appears that measures or precautions previously required are unnecessary, the city inspector shall waive them in writing. The city inspector shall require certification of plans and specifications and supervision of work by a licensed professional engineer unless he determines it is not necessary under the circumstances.
(Ordinance 361 adopted 3/28/18)
The city inspector shall order all construction and development work stopped on any site upon which he finds a substantial violation of this division and shall post the premises with a stop-work order which shall remain in effect until the violation has been corrected.
(Ordinance 361 adopted 3/28/18)
No excavation, grading or filling shall be permitted which interferes with the natural drainage of the general area surrounding the site. All existing watercourses shall be preserved, except that such watercourses may be relocated or piped, provided that they will not thereby be creating any interference with the riparian or drainage rights, or easements of other property owners, and provided that no drainage shall be made onto public land, or connected with public facilities without the express approval of the city.
(Ordinance 361 adopted 3/28/18)
It shall be a violation of this division to commence any site clearing, excavation, grading, filling or other construction activities without the proper placement of engineer-designed erosion and sedimentation controls which are necessary and reasonable to control erosion.
(Ordinance 361 adopted 3/28/18)
