This code shall be referred to as the Bothell storm water and drainage control code and shall be codified as Chapter 18.04 BMC. References throughout this chapter to the city’s storm drainage system, storm drain system, storm sewer system, or the like shall be deemed references to the storm and surface water utility of the city. (Ord. 2142 § 5, 2014; Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996; Ord. 843 § 1, 1977).
The city council finds that the ordinance codified in this chapter is necessary in order to minimize water quality degradation by preventing the siltation of the city’s creeks, streams, rivers, lakes, and other water bodies; to protect property owners adjacent to developing land from increased runoff rates which could cause flooding and erosion of abutting property; to promote sound development policies which respect and preserve the city’s watercourses; to ensure the safety of city roads and rights-of-way; and to decrease surface water damage to public and private property. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996; Ord. 843 § 1, 1977).
This code constitutes an exercise of the police power of the city to promote the public health, safety and welfare and its provisions shall be liberally construed for the accomplishment of that purpose. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
A. ROW Permit. A right-of-way invasion permit shall be required whenever storm drainage system additions, betterments or extensions are made within the street right-of-way or a public easement.
B. Storm Drainage Side Sewer Permit. A storm drainage side sewer permit shall be required for the construction of any storm drainage side sewer or on-site storm drainage system.
C. Grading Permit. A grading permit shall be required whenever grading activities are performed.
D. A right-of-way invasion permit, storm drainage side sewer permit and grading permit shall expire two years from the date of issuance; except that permits issued through December 31, 2011, shall expire four years from the date of issuance. The director is authorized to approve a request for an extended expiration date where a construction schedule is provided by the applicant and approved prior to permit issuance.
E. Every permit which has been expired for less than one year may be renewed for a period of one year for an additional fee, based on the valuation of the work remaining, as long as no changes have been made to the originally approved plans. For permits that have been expired for longer than one year, a new permit must be obtained and full new fees paid. No permit shall be renewed more than once.
Exemption from the permit requirements of this title shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of the BMC or the BSWDM. (Ord. 2043 § 2 (Exh. B), 2010; Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
The city shall use reasonable diligence and care to maintain free flow of storm water and to avoid any interruption in service. The use of the storm drainage side sewer on the premises of the user shall be at the risk of the user, and the responsibility and the liability of the city shall cease at the connection of the storm drainage side sewer to the main or catchbasin. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
The public works director bearing proper credentials and identification shall be permitted, during city business hours, to enter property to which storm sewer service is being supplied by the city for the purpose of inspecting the condition of exterior connections to the city system and related apparatus. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
(Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
Additions, betterments and extensions to the existing storm drainage system of the city shall be made in accordance with the storm drainage comprehensive plan and Bothell Standards adopted by the city council and shall require a permit. The fee for said permit shall be as established by resolution of the city. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
The cost of making additions, betterments and extensions to the existing storm drainage system may be paid from such sources and by such means as the city council from time to time may direct, in accordance with the provisions of the laws of the state as the same now exist or as they may hereafter be amended. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).

A deposit, including but not limited to estimated engineering, inspection and legal costs, shall be posted with the department of public works upon submittal of the construction drawings. Any cost differential between the estimated and the actual cost incurred shall be paid to the city upon demand. If the deposit is more than the actual cost incurred, the city shall refund any unused portion to the developer.
D. A performance bond, in a form approved by the city attorney, and written by a surety authorized to do business in the state, shall be provided prior to the issuance of the permit.
E. If any work is to be performed in the public right-of-way, an appropriate right-of-way invasion permit must be obtained and a surety bond and insurance must be provided to the city. The insurance type and amount shall be specified by the director of public works. The insurance shall name the city as an additional insured, shall be primary to any other insurance available to the city and shall not be cancelable without 30 days’ prior written notice to the city. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
All additions, betterments and extensions shall be designed and constructed to comply with Bothell Standards. The developer shall, before city acceptance of the construction, convey the same to the city, in a form satisfactory to the city. Such conveyance shall contain the owner’s warranty of good title and the right to convey the same free and clear of all claims or other encumbrances and a warranty that the facilities as constructed are of the type, character and construction per plans, functioning and operating as an integral part of the storm drainage system. In the event any portion of such construction is situated on private property, the developer shall be required to procure private easements, fully executed and acknowledged, in a form satisfactory to the city. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
Prior to release of any construction bond or surety, the developer shall covenant to replace, repair or correct any defect in workmanship or materials in the conveyed facilities that shall occur or otherwise arise during a period of two years following date of acceptance by the city, and shall provide a bond to secure the covenant. The applicant shall further waive and release the city from any and all future claims for damages on behalf of himself and his successors in interest which may be suffered by reason of connection to the water system. The bond shall be in a form acceptable to the city attorney. (Ord. 2023 § 1 (Exh. A), 2009).

The city shall enter into a reimbursement agreement to pay for the oversizing. The developer shall provide the city an itemized accounting of construction costs for the storm drainage main extension constructed, together with an estimated cost of pipe and other materials of the size which would serve the development. The developer shall also provide certification that all material and labor charges have been paid. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
It is unlawful to plant willow, poplar, cottonwood, soft maples, gum or any other tree or any shrub whose roots are likely to obstruct public or private storm drainage main or facility within 30 feet of the main or facility. The public works director is authorized to remove any trees or shrubs from any public street, or the roots of any trees or shrubs which extend from any public or private storm mains or facilities; provided, however, that he shall give 10 days’ notice in writing to the owner or occupant of the abutting property to remove the same. If such owner or occupant fails or refuses to do so, the reasonable cost of such removal when done by the city shall be a lien upon the abutting property from which such trees or shrubs are removed. The city attorney is authorized, empowered and directed to collect such charge by suit maintained in the name of the city as plaintiff, in any court of competent jurisdiction. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).

It is unlawful for any person to make an opening in any public storm main or side sewer, or to connect or disconnect any private storm drain or side sewer therewith, or to lay, repair, alter or construct any storm drain to be connected to or disconnected from a public storm drain unless such person has first obtained a storm drainage side sewer permit from the public works director. Upon approval of plans and specifications and upon payment of all fees and charges, including connection charges, assessments, if any, and upon provision of an approved surety bond, if required, the public works director shall issue a permit to perform the work. The public works director shall have the right and is authorized to refuse to issue a permit to any person or contractor where reasonable grounds exist upon which to conclude that such person may refuse to or be unable to comply with the provisions of this code. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
No person shall install an on-site storm system without first obtaining a permit for such installation from the department of public works. The fee for said permit shall be as established by resolution of the city. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).

A), 2009; Ord. 1634 § 1, 1996).
A. If a storm drainage side sewer, in the public right-of-way, belonging to another property owner is to be used, written permission from the property owner for such use must accompany the storm drainage side sewer application.

When two or more structures, not in common ownership, are to be connected on one storm drainage side sewer, easements running with the land must be executed and recorded with the county auditor (department of records and elections). The easements shall be approved as to form by the city attorney and shall ensure that all properties involved shall have perpetual use of the storm drainage side sewer and shall contain provisions for joint responsibility for costs of maintenance, repair and access, and shall be signed by the owners of the properties subject to the easements. The easement shall be acknowledged and must be recorded by the property owners with the county auditor (department of records and elections) before a permit shall be issued for construction. (Ord. 2023 § 1 (Exh. A), 2009; Ord. 1634 § 1, 1996).
Where physical conditions render compliance with the conditions of this code governing storm drainage side sewer installation impracticable, the public works director may issue a special permit for installation of a storm drainage side sewer requiring compliance with the provisions insofar as is reasonably possible, but such permit shall be issued only upon condition that the property owner execute and deliver to the city an instrument in form furnished by the city agreeing to save harmless and indemnify the city for any damage or injury resulting from special permit conditions.
