    City of Vancouver

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

    Excerpt from Vancouver Municipal Code


    Section 14.09.020 Stormwater management.

    Pursuant to RCW 35.67, the City of Vancouver water and sewer utility establishes provisions for storm and surface water management. Such provisions shall give the utility authority and responsibility for carrying out the comprehensive stormwater plan, including responsibility for planning, design, construction, maintenance, administration and operation of all city stormwater facilities, as well as establishing standards for design, construction and maintenance of improvements on private property where these may effect stormwater management.

    Section 14.09.030 Ownership of city stormwater facilities and assets.

    Title and all other incidents of ownership of the following assets are vested in the water and sewer utility:

    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.

    Section 14.09.035 Inspection and Approval.

    All work done under a permit issued pursuant to this chapter shall be subject to the inspection and approval by the director or designee, and the work shall not be deemed completed until it has been inspected and approved as satisfactory.

    Section 14.09.050 Surface water program and stormwater capital plan.

    The stormwater capital plan which is attached to SR 229-94 is adopted as the city's stormwater plan. Said plan shall be reviewed and updated by staff periodically as necessary to meet the needs of the system and returned for public hearing and may then be added to or amended. Such plan provides a practical and reasonable means to relieve the stormwater issues of the city and to preserve the integrity of the city's water supply and to protect its wastewater collection and treatment system.

    Chapter 14.25 STORMWATER CONTROL

    Section 14.25.120 Enforcement.

    It shall be unlawful to violate the provisions of this chapter. Enforcement of this chapter shall be governed by VMC Title 22.

    Section 14.25.210 Runoff treatment.

    A. Runoff treatment in new development and redevelopment shall follow the requirements of the City's General Requirements and the Stormwater Manual.

    B. Stormwater treatment BMPs shall be selected, sited, designed and constructed in accordance with the requirements detailed in the City's General Requirements and the Stormwater Manual.

    Section 14.25.215 Source control of pollution.

    Source control BMPs shall be applied to all projects. Source control BMPs shall be selected, designed and maintained in compliance with the Stormwater Manual, the City’s General Requirements, and VMC 14.26.

    Section 14.25.220 Flow control.

    A. Flow control in new development and redevelopment shall follow the requirements of Appendix 1 of the Permit.

    B. Natural drainage flow routes of surface water shall be maintained, and discharges from the site shall occur at the natural location and elevation, to the maximum extent practicable. The manner by which runoff is discharged from the project site must not cause a significant adverse impact to downstream receiving waters and down gradient properties. All outfalls require energy dissipation.

    C. Flow control facilities shall be selected, sited, designed and constructed in compliance with the Stormwater Manual and with the City’s General Requirements.

    D. UIC wells used to manage stormwater for flow control shall meet the non-endangerment standard (Chapter 173-218WAC); which means the UIC well shall be designed, constructed, operated, maintained, and decommissioned in a manner that protects groundwater quality (Chapter 173-200WAC).

    E. Design of stormwater collection and conveyance systems shall be in accordance with the City’s General Requirements.

    F. Hydrologic and hydraulic analysis shall be in accordance with the Stormwater Manual and with the General Requirements.

    G. Every new development and redevelopment must demonstrate that sufficient downstream conveyance capacity exists to accommodate the increased flows from the project. Hydrologic and hydraulic analysis will be required when sufficient capacity has not been established.

    Section 14.25.225 Low impact development.

    It is recommended that new development and redevelopment projects utilize Low Impact Development practices. LID practices shall refer to the Low Impact Development Technical Guidance Manual for Puget Sound, the Stormwater Manual, and the General Requirements for design recommendations. All uses of LID practices shall meet applicable regulations and requirements.

    Section 14.25.227 Wetlands protection.

    Wetlands Protection required under Minimum Requirement #8 may also be addressed in VMC Chapter 20.740, Critical Areas. Where provisions of this chapter or manuals adopted under this chapter conflict with other manuals adopted under this section, or with other provisions of the Vancouver Municipal Code, the more stringent requirements, which have the most protective effect on water quality and wetland function shall apply.

    Section 14.25.230 Ownership and maintenance.

    A. Ownership

    1. City Ownership of Stormwater Facilities. Stormwater systems and facilities that collect, convey, treat and/or infiltrate runoff from public rights-of-way will be owned and maintained by the City, unless it is demonstrated to the satisfaction of the Director that the stormwater facilities can be adequately maintained by private parties.
    2. Private Ownership of Stormwater Facilities. Owners of private stormwater systems and facilities that collect, convey, treat and/or infiltrate runoff from private properties are responsible for the operation and maintenance of those facilities.
    3. Ownership and maintenance responsibility for stormwater facilities shall be specified on a recorded plat, short plat, or covenant.

    B. Maintenance standards. All stormwater facilities shall be inspected and maintained so that they operate as designed. Inspection and maintenance shall comply with the “Maintenance Standards for Drainage Facilities” as specified in Volume V-Runoff Treatment BMPs in the Stormwater Manual, and with an approved operations and maintenance manual. [see below links]

    C. Short-term Maintenance.

    1. To insure satisfactory operation of new private stormwater facilities, the applicant constructing the facility shall maintain it for two years after completion of the project.
    2. For stormwater facilities within a public road right-of-way or on land owned by the City, the applicant, after satisfactory completion of the stormwater facilities, shall post and maintain a maintenance bond or other security acceptable to the Director. The two-year maintenance bond will cover the cost of design defects or failures in workmanship of the facilities. The amount of the maintenance bond shall be ten percent of the construction cost of the stormwater facilities.
