Chapter 21.10 STORM WATER MANAGEMENT

(1) The purpose of this chapter is to ensure water quality standards and help protect receiving waters, and their beneficial uses, in accordance with the Federal Clean Water Act and state requirements, by establishing minimum requirements for measures that must be implemented to control the quantity and quality of storm water that is produced or affected by development, redevelopment or construction site activity.

(2) The provisions of this chapter shall apply to all development, redevelopment and construction site activity that occurs within the incorporated area of the city of Puyallup. (Ord. 3130 § 1 (Exh. A), 2016; Ord. 2951 § 1 (Exh. A), 2010).

21.10.030 Definitions.

For the purposes of this chapter the following definitions describe the meaning of the terms used in this chapter:

(2) “Director” means the public works director or the director’s designated representative.

(3) “Drainage manual administrator” means the plan approval authority.

(4) “Hard surface” means an impervious surface, a permeable pavement, or a vegetated roof.

(5) “Hazardous substance” means any liquid, solid, gas or sludge, including any material, substance, product, commodity, or waste, regardless of quantity, that exhibits any of the physical, chemical, or biological properties described in WAC 172-303-090 or 173-303-100.

(6) “Illicit connection” means any infrastructure connection to the MS4 that is not intended, permitted, or used for collecting and conveying stormwater or non-stormwater discharges allowed as specified in this title. Examples include sanitary sewer connections, floor drains, channels, pipelines, conduits, inlets or outlets that are connected directly to the MS4.

(7) “Illicit discharge” means any discharge to the MS4 that is not composed entirely of stormwater or of non-stormwater discharges allowed as specified in this title.

(8) “Impervious surface” means a non-vegetated surface that either prevents or retards the entry of water into the soil mantle as under natural conditions prior to development. A non-vegetated surface area which causes water to run off the surface in greater quantities or at an increased rate of flow from the flow present under natural conditions prior to development. Common impervious surfaces include, but are not limited to, rooftops, walkways, patios, driveways, parking lots or stormwater areas, concrete or asphalt paving, gravel, packed earthen materials and oiled, macadam or other surfaces which primarily impede the natural infiltration of stormwater. Open, uncovered retention/detention facilities shall not be considered as impervious surfaces for the purposes of determining whether the thresholds for application of minimum requirements are exceeded. Open, uncovered retention/detention facilities shall be considered impervious surfaces for purposes of runoff modeling.

(9) “Local government(s)” shall mean or include the city of Puyallup.

(10) “Low impact development (LID)” means a stormwater and land use management strategy that strives to mimic pre-disturbance hydrologic processes of infiltration, filtration, storage, evaporation and transpiration by emphasizing conservation, use of on-site natural features, site planning, and distributed stormwater management practices that are integrated into a project design. Examples of LID include: permeable paving, bioretention facilities, rain gardens, biofiltration facilities, green roofs, rainwater collection, runoff dispersion, tree retention, soil amendments, clustered site design, native landscaping/minimization of turf lawn, minimal excavation foundation systems, retention of natural site contours, impervious surface minimization, etc.

(11) “Low impact development principles” means land use management strategies that emphasize conservation, use of on-site natural features, and site planning to minimize impervious surfaces, native vegetation loss, and stormwater runoff.

(12) “MS4” means municipal separate storm sewer system.

(13) “Municipal separate storm sewer system” means a conveyance or system of conveyances including roads and drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels, or storm drains: (a) owned and operated by the city; (b) designed or used for collecting and conveying stormwater; and (c) which is not a combined sewer.

(14) “NPDES stormwater permit,” or the “National Pollutant Discharge Elimination System and state waste discharge general permit for discharges from small municipal separate storm sewers in western Washington,” means the Phase II Western Washington Municipal Stormwater Permit administered by the Washington Department of Ecology under authority for the national program for issuing, modifying, revoking and reissuing, terminating, monitoring and enforcing permits and imposing and enforcing pretreatment requirements, under Sections 306, 402, 318 and 405 of the Federal Clean Water Act, for the discharge of pollutants to surface waters of the state.

(17) “Should,” as used in the Stormwater Manual, means shall, unless the plan approval authority permits or allows otherwise.

(18) “Stormwater” means that portion of precipitation that does not naturally percolate into the ground or evaporate, but flows via overland flow, interflow, pipes, and other features of a stormwater drainage system into a defined surface water body, or a constructed infiltration facility.

(19) “Stormwater Manual” means the most current version, as approved for city use by the council, of the Stormwater Management Manual for Western Washington, published by the Washington State Department of Ecology, as presently constituted or as may be amended, updated, supplemented, or revised.
