Prior legislative history: Ord. 415.
(A) 
Findings of Fact. The city of Granite Falls finds that:
(1) 
Stormwater pollution is a problem associated with land utilization, development, redevelopment and the common occurrence of potential pollutants such as pesticides, fertilizers, petroleum products, pet wastes, and numerous others.
Land utilization, development and redevelopment is also known to increase both the volume and duration of peak flows. The resulting erosion, scouring, and deposition of sediment affect the ecological balance in the stream.
Sedimentation and stormwater pollution cause diversity of species to decrease and allow more tolerant (and usually less desirable) species to remain.
(2) 
Development and redevelopment of land have led to:
(a) 
Water quality degradation through discharge of nutrients, metals, oil and grease, toxic materials, and other detrimental substances including, without limitation, insect and weed control compounds, drainage, and storm and surface water runoff problems within the city; and
(b) 
Safety hazards to both lives and property posed by uncontrolled water runoff on streets and highways.
(3) 
Continuation of present stormwater management practices, to the extent that they exist, will lead to further water quality degradation, erosion, property damage, and endanger the health and safety of the inhabitants of the city.
(4) 
In the future such problems and dangers will be reduced or avoided if existing properties and future developers, both private and public, provide for stormwater quality and quantity controls.
(5) 
Stormwater quality and quantity controls can be achieved when land is developed or redeveloped by implementing appropriate best management practices (BMPs).
(6) 
Best management practices can be expected to perform as intended only when properly designed, constructed and maintained.
(B) 
The city finds that this chapter is necessary, to comply with state law, in order to:
(1) 
Minimize or eliminate water quality degradation.
(2) 
Prevent erosion and sedimentation in creeks, streams, ponds, lakes and other water bodies.
(3) 
Protect property owners adjacent to existing and developing land from increased runoff rates which could cause erosion of abutting property.
(4) 
Preserve and enhance the suitability of waters for contact recreation, fishing, and other beneficial uses.
(5) 
Preserve and enhance the aesthetic quality of the water.
(6) 
Promote sound development policies which respect and preserve city surface water, ground water and sediment.
(7) 
Enhance the safety of roads and rights-of-way.
(8) 
Decrease stormwater-related damage to public and private property from existing and future runoff.
(9) 
Protect the health, safety and welfare of the inhabitants of the city.
(C) 
Purpose. The provisions of this chapter are intended to guide and advise all who conduct new development or redevelopment within the city. The provisions of this chapter establish the minimum level of compliance which must be met to permit a property to be developed or redeveloped within the city. It is the purpose of this chapter to:
(1) 
Minimize water quality degradation and sedimentation in streams, ponds, lakes, wetlands and other water bodies;
(2) 
Minimize the impact of increased runoff, erosion and sedimentation caused by land development and maintenance practices;
(3) 
Minimize adverse impacts of alterations on ground and surface water quantities, locations and flow patterns;
(4) 
Decrease potential landslide, flood and erosion damage to public and private property;
(5) 
Promote site planning and construction practices that are consistent with natural topographical, vegetational and hydrologic conditions;
(6) 
Maintain and protect the city stormwater management infrastructure and those downstream;
(7) 
Provide a means of regulating clearing and grading of private and public land while minimizing water quality impacts in order to protect public health and safety; and
(8) 
Provide minimum development regulations and construction procedures which will preserve, replace or enhance, to the maximum extent practicable, existing vegetation to preserve and enhance the natural quality of lands, wetlands, and water bodies;
(9) 
To promote the implementation of stormwater best management practices (BMPs) by the residents and businesses of the city.

(Ord. 916 § 1, 2016)
(A) 
Responsibilities. There is hereby created and established, pursuant to Chapters 35A.80 and 35.67 RCW, a storm and surface water utility to be known as the storm drainage utility. All references to the "utility" in this chapter refer to the storm drainage utility. The utility will have primary authority and responsibility for carrying out the city's comprehensive drainage and storm sewer plan, maintenance, administration, and operation of all city storm and surface water facilities, as well as establishing standards for design, construction, and maintenance of improvements on private property where these may affect storm and surface water and management.
(B) 
Administrator of Utility. The mayor or his/her designee shall be the administrator of the utility.
(C) 
Ownership of City Stormwater Facilities and Assets. Title and all other incidents of ownership of the following assets are vested in the utility:
(1) 
All properties, interests, and physical and intangible rights of every nature owned or held by the city, however acquired, insofar as they relate to or concern storm or surface water runoff.
(2) 
All properties, interests and rights acquired by adverse possession or by prescription directly or through another in and to the drainage or storage, or both, of storm or surface waters, or both, through, under or over land, watercourses, sloughs, streams, ponds, lakes, and swamps. The properties, interests and rights so transferred shall begin from a point where storm or surface waters first enter the storm and surface water system of the city and shall end at a point where the storm or surface waters exit from the storm and surface water system of the city. The width of the properties, interests and rights so transferred shall be to the full extent of inundation caused by storm or flood conditions.
(3) 
All funds on deposit in the city storm drainage fund and future revenues of said fund.
(Ord. 795 § 1, 2010)
The 2019 Department of Ecology Stormwater Management Manual for Western Washington, as amended by Appendix 1 of the NPDES Phase II municipal stormwater permit, as now or hereafter amended, is hereby adopted as the city's minimum stormwater regulations and as a technical reference manual and is hereinafter referred to as the "stormwater manual."
(Ord. 796 § 1 (Exh. A), 2010; Ord. 923 § 1 (Exh. A), 2016; Ord. 1029 § 1 (Att. A), 2022)
Stormwater management review and approval by the city is required when any development or proposed project meets or exceeds the threshold conditions defined in the stormwater manual (e.g., new impervious area, drainage system modifications, redevelopments, etc.) and is subject to a city development permit or approval requirement.
(Ord. 796 § 1 (Exh. A), 2010)
(A) 
Unless otherwise specified in this chapter, all standards, definitions, and requirements shall be in accordance with the stormwater manual.
(B) 
Plan and Report Submittal. Stormwater site plans, supporting technical analyses and other required documentation shall conform to the requirements contained in the stormwater manual.
(C) 
Where to Submit. All stormwater site plans prepared in connection with any of the permits and/or approvals set forth in this chapter shall be submitted to the public works supervisor.
(D) 
All plans, drawings and calculations designed to control surface water and subsurface water, submitted to the city, will be prepared by a licensed professional engineer, registered in the state of Washington, or by a person qualified as set forth in the stormwater manual, and those plans, drawings and calculations will be stamped showing that engineer's registration, if applicable.
(E) 
Interpretation. The provisions of this chapter shall be held to be minimum requirements in their interpretation and application and shall be liberally construed to serve the purposes of this chapter.
(F) 
More Strict Standard Applies. When any provision of any other ordinance of the city's regulations conflicts with this chapter, that which provides greater environmental protection shall apply unless otherwise provided for in this chapter.
(G) 
Determining Construction Site Sediment Damage Potential. Any person submitting a stormwater site plan must also determine the construction site sediment damage potential. Qualified personnel must use the rating system described in Appendix 7 of the NPDES Phase II permit to determine the site's potential to discharge sediment.
(Ord. 796 § 1 (Exh. A), 2010)
(A) 
The city allows and encourages low impact development (LID) best management practices (BMPs), as an alternative to conventional stormwater management systems that rely on detention ponds and closed conveyance. Low impact development is intended to manage runoff close to the source of generation and to mimic the predeveloped hydrologic condition of a site.
(B) 
Low impact development is accomplished first through minimizing the impervious surface coverage and second by managing runoff through dispersion, infiltration, evapotranspiration, or a combination of these approaches. Use of LID BMPs may reduce or eliminate the need for conventional detention facilities but does not remove the obligation to comply with the minimum requirements of the stormwater manual.
(C) 
A variety of BMPs to minimize impervious surfaces and to manage stormwater have been developed and tested for use in Western Washington. These BMPs and the overall LID approach are described in the stormwater manual as well as the LID Technical Guidance Manual for Puget Sound (LID manual).
(D) 
The menu of LID BMPs identified in the LID manual is accepted by the city for use in stormwater site plans to address the minimum requirements for flow control and runoff treatment in this chapter, subject to the specifications, performance standards, and design criteria in the LID manual and review and approval under this chapter.
(E) 
A covenant or easement shall be recorded with the Snohomish County auditor's office for each lot containing or served by bioretention facilities in a form approved by the city attorney. The covenant shall identify requirements and liability for preservation and maintenance of low impact development facilities approved under this chapter and privately held in individual or undivided ownership or intended for public ownership, shall restrict conversion of LID facilities, and shall grant the city access to low impact development facilities on private property to allow inspection, maintenance, and repair.
(Ord. 796 § 1 (Exh. A), 2010; Ord. 923 § 1 (Exh. A), 2016)
(A) 
Application. Existing development, current activities, and new development activities that are not listed in the exemptions of subsection (D) of this section are required to apply stormwater BMPs listed in the 2019 Department of Ecology Stormwater Management Manual for Western Washington, Volume IV. A BMP not included in this manual may be approved by the responsible official if the proponent demonstrates that it provides equivalent effectiveness. An exemption from the requirement to use BMPs does not provide an exemption allowing prohibited discharges.
(B) 
Implementation. In applying the 2019 Department of Ecology Stormwater Management Manual for Western Washington for existing development, the responsible official shall first require the implementation of nonstructural source control BMPs. If these are not sufficient to prevent contaminants from entering surface and stormwater or groundwater, the responsible official may require implementation of structural source control BMPs or treatment BMPs, using AKART.
(C) 
Inspections. The city shall have the ability to inspect private property to monitor for proper implementation of stormwater BMPs pursuant to GFMC § 13.20.280.
(D) 
Exemptions. The following persons or entities are exempt from the provisions of this section unless the responsible official determines the alternative BMPs to be ineffective at reducing the discharge of contaminants or activities are causing a prohibited discharge:
(1) 
Persons implementing BMPs through another federal or state regulatory or resource management program; provided the responsible official may perform inspections to ensure compliance with this chapter. If the other program requires the development of a best management practices plan, the person shall make that plan available to the city upon request;
(2) 
Persons engaged in forest practices regulated under WAC Title 222, except for Class IV general forest practices as defined under Chapter 222-16 WAC; and
(3) 
Persons conducting normal residential activities at property containing a single-family detached dwelling, duplex or triplex and modifications to it on a lot approved for such use, unless the responsible official determines that these activities pose a hazard to public health, safety or welfare; endanger any property; or adversely affect the safety and operation of city right-of-way, utilities, and/or other property owned or maintained by the city.
(Ord. 1029 § 1 (Att. A), 2022)
(A) 
All stormwater facilities required under this chapter shall be constructed and maintained as set forth in the stormwater manual and the permits and/or approvals of the city.
(B)

(1) 
The person or persons holding title to the property and the applicant required to construct a stormwater facility shall remain responsible for the facility's continual performance, operation, and maintenance in accordance with the standards and requirements of the stormwater manual, this chapter, and the permits and/or approvals of the city and shall remain responsible for any liability as a result of these duties. This requirement shall apply to all facilities not otherwise accepted by the city for maintenance as set forth in subsection (C) of this section.
(2) 
The city shall have authority to periodically enter upon the property and inspect the facilities to ensure such compliance and to issue orders requiring maintenance and/or repair. In the event that the titleholders or other responsible parties do not effect such maintenance and/or repairs, the city may perform such work, and the cost thereof shall be recoverable by the city from said titleholders or other responsible parties and/or by filing a lien against the property.
