City of Everett


The City of Everett has enacted a Stormwater Ordinance in order to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing in watersheds within this jurisdiction.  The City of Everett is the permitting authority for all land disturbing activities and requires the land owner to maintain all on-site stormwater control facilities and all open space areas (e.g. parks or “green” areas) required by the approved stormwater control plan. The City of Everett will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. The City of Everett, under the NPDES program, also has the authority to inspect properties for noncompliance and can issue a notice of violation (NOV) for any deficiency or infraction onsite. Property owners are responsible for the maintenance of any stormwater facilities or practices located on the property. The City of Everett  has the authority to inspect stormwater facilities and practices in order to ascertain that they are properly maintained and functioning.

14.28.430 City assumption of operation and maintenance.

The city may assume the operation and maintenance of retention/detention or other drainage treatment/abatement facilities after the expiration of the two-year operation and maintenance period in connection with the subdivision of land if:

A. All of the requirements of Section 14.28.420 have been fully complied with; and

E. The developer has supplied to the city an accounting of capital, construction, and operation and maintenance expenses or other items for the drainage facilities up to the end of the two-year period.

In the event that the city elects not to assume the operation and maintenance responsibility for the facilities, it will be the responsibility of the developer to make arrangements with the occupants or owners of the subject property for assumption of maintenance in a manner subject to the approval of the city engineer or in accordance with the city of Everett stormwater management manual. Such arrangements shall be completed and approved prior to the end of the two-year period of developer responsibility.

If the city elects not to assume operation and maintenance responsibility, the drainage facilities shall be operated and maintained in accordance with the arrangements as approved by the city engineer. The city may inspect the facilities in order to ensure continued use of the facilities for the purposes for which they were built and in accordance with these arrangements.

14.28.460 Enforcement.

A. The city reserves the right to enter the subject property from time to time to ascertain that all drainage facilities are functioning. In the event deficiencies are found, the property owner shall make minor corrections as are necessary within thirty days of the date of notice by the city. More substantive corrections, as determined by the city, will be completed on a negotiated time schedule, but in no event will the schedule extend past six months.

B. Any person or persons violating this chapter or rule or regulation adopted hereunder, or by any act of commission or omission procures, aids, or abets such violation, shall be guilty of a misdemeanor and, upon conviction, shall be punished by a fine not to exceed one thousand dollars and/or imprisonment for a term not to exceed ninety days. Each day such violation continues shall be considered an additional misdemeanor offense.

C. Any condition which constitutes or will constitute a violation of any of the provisions of this chapter or rules or regulations adopted hereunder shall constitute a nuisance for which the city may seek legal or equitable relief to enjoin any acts or practices or abate any said conditions. In the event the property owner shall fail to make corrections within thirty days of the date of notice by the city, or on a timetable established by the city, not to exceed six months, the city may revoke the right to occupancy of the subject property, may charge the property owner with a misdemeanor punishable by fines, and may enter onto the subject property and take such corrective action as may be required to make the drainage facilities perform as required by the approved drainage plan. All costs for corrective measures and enforcement actions shall be borne by the property owner.

D. Notwithstanding any other provision of this chapter, whenever the city engineer finds that a violation of this chapter or rules or regulations adopted hereunder has created or is creating an unsanitary, dangerous, or other condition which, in his judgment, constitutes an immediate hazard, he may suspend or revoke any permit for which the approval of a drainage plan is required on the project or development where the violation exists and suspend or terminate operations under the permit immediately.

Any person causing material to be discharged to or enter the drainage system of the city shall be liable for all costs incurred by the city or others in cleaning up or correcting said action and may be charged with a misdemeanor punishable by fines.

E. Penalty or enforcement provisions provided herein shall not be exclusive, and the city may pursue any remedy or relief deemed appropriate.
