City of Kirkland
The City of Kirkland 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 Kirkland 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 Kirkland will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. The City of Kirkland, 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 Kirkland has the authority to inspect stormwater facilities and practices in order to ascertain that they are properly maintained and functioning.

Title 15 Water and Sewage; Chapter 15.52 Surface Water Management
The city council finds that this chapter is necessary to promote sound development policies and construction procedures which respect and preserve the city’s watercourses; to minimize water quality degradation and control of sedimentation of creeks, streams, ponds, lakes, and other water bodies; to protect the life, health, and property of the general public; to preserve and enhance the suitability of waters for contact recreation and fish habitat; to preserve and enhance the aesthetic quality of the waters; to maintain and protect valuable ground water quantities, locations, and flow patterns; to insure the safety of city roads and rights-of-way; and to decrease drainage-related damages to public and private property. (Ord. 3711 § 4 (part), 1999)
15.52.060 Design and construction standards and requirements.
(a) The design and construction standards and requirements shall meet or exceed the thresholds, definitions, minimum requirements, and exceptions/variances criteria found in Appendix I of the Western Washington Phase II Municipal Stormwater Permit. To meet these criteria, the following are adopted:
(1) The 2016 King County Surface Water Design Manual;
(2) The 2016 King County Stormwater Pollution Prevention Manual;
(3) The city’s pre-approved plans and policies which include the City of Kirkland Addendum to the 2016 King County Surface Water Design Manual as presently written or hereafter amended.
(b) Unless otherwise provided, it shall be the developer’s and property owner’s responsibility to design, construct, and maintain a system which complies with the standards and minimum requirements as set forth in the pre-approved plans.
(c) In addition to providing drainage facilities as required in this section and as outlined in the pre-approved plans, the developer, property owner, and/or business owner/operator shall provide source control best management practices as described in the 2016 King County Stormwater Pollution Prevention Manual, such as structures and/or a manual of practices designed to treat or prevent storm water pollution arising from specific activities expected to occur on the site. Examples of such specific activities include, but are not limited to, carwashing at multifamily residential sites and oil storage at auto repair businesses.
(d) The city will inspect all permanent drainage facilities prior to final approval of the relevant permit. All facilities must be clean and fully operational before the city will grant final approval of the permit. A performance bond may not be used to obtain final approval of the permit prior to completing the drainage facilities required under this chapter.
(e) Prior to final approval of the drainage facilities, the property owner of all drainage facilities shall submit an irrevocable license to enter the property for the purposes of inspection. The following language must be included in the irrevocable license to enter:
(1) A statement that the property owner is to be responsible for the maintenance of drainage facilities on the property;
(2) A statement granting the public works director or designee the right to enter the property for the purposes of inspecting the drainage facilities; and
(3) A statement that the public works director shall have the authority to order repair or cleaning of the drainage facilities if the owner does not take action to conduct this work or if the site poses a threat to public health and safety.
(f) Adjustment Process. Any developer proposing to adjust the requirements for, or alter design of, a system required as set forth in the pre-approved plans must follow the adjustment process as set forth in the pre-approved plans.
(g) Other Permits and Requirements. It is recognized that other city, county, state, and federal permits may be required for the proposed action. Further, compliance with the provisions of this chapter when developing and/or improving land may not constitute compliance with these other jurisdictions’ requirements. To the extent required by law, these other requirements must be met. (Ord. 4538 § 10, 2016: Ord. 4351 § 1, 2012: Ord. 4214 § 1, 2009: Ord. 3711 § 4 (part), 1999)
15.52.100 Source control best management practices.
BMPs shall be applied to any business or residential activity that might discharge contaminants to a public drainage facility, natural drainage system, surface and storm water, or ground water. Contaminants shall be controlled by implementing appropriate source control BMPs, as described in the 2016 King County Stormwater Pollution Prevention Manual. Discharges associated with activities not addressed in the 2016 King County Stormwater Pollution Prevention Manual shall be controlled using BMPs reviewed and accepted by the city. Failure to implement such practices shall constitute a violation of this chapter. (Ord. 4666 § 4, 2018: Ord. 4538 § 14, 2016: Ord. 4200 § 20, 2009: Ord. 3711 § 4 (part), 1999)
