THRESHOLD: All Residential development in the City of Renton require either Drainage Evaluation or Drainage Review.
Drainage Review is triggered for any residential development in the City of Renton that results in:
2,000 square feet or more of new plus replaced impervious surface; OR
7,000 square feet of land disturbing activity; OR
Construction or modification of a pipe/ditch that is 12 inches or more in size/depth, or received storm water runoff
or surface water from a drainage pipe/ditch that is 12 inches or more in size/depth; OR
The project contains or is adjacent to a flood, erosion, or steep slope hazard area as defined in RMC 4-3-050, or is
located within a Landslide hazard area in RMC 4-3-050.
The type of drainage review is determined based upon the project and site characteristics.
Those developments that do not trigger Drainage Review will require a Drainage Evaluation to ensure storm water is
managed properly onsite to confirm that there is no erosion or flooding potential.
DEFINITIONS:
Impervious surface means a non-vegetated surface area that either prevents or retards the entry of water into the soil
mantle as under natural conditions before development; or that causes water to run off the surface in greater
quantities or at an increased rate of flow compared to the flow present under natural conditions prior to development
(e.g., roofs, driveways, etc.). Common impervious surfaces include, but are not limited to, roof, walkways, patios,
driveways, parking lots, or storage areas, areas that are paved, graveled or made of packed or oiled earthen materials
or other surfaces that similarly impede the natural infiltration of surface water or stormwater. For the purposes of
applying the impervious surface thresholds, permeable pavement, vegetated roofs, and pervious surfaces with
underdrains designed to collect stormwater runoff are considered impervious surface while an open uncovered flow
control or water quality facility is not.
Land Disturbing Activity means any activity that results in a change in the existing soil cover (both vegetative and non-
vegetative) and/or the existing soil topography. Land disturbing activities include, but are not limited to demolition,
construction, clearing, grading, filling, excavation, and compaction. Land disturbing activity does not include tillin g
conducted as part of agricultural practices, landscape maintenance, or gardening.
New impervious surface means the addition of a man-made, modified, or compacted surface like roofs, pavement, gravel,
or dirt; or the addition of a more compacted surface, such as resurfacing by upgrading from dirt to gravel, asphalt, or
concrete; upgrading from gravel to asphalt, or concrete; or upgrading from a bituminous surface treatment (“chip
seal”) to asphalt or concrete. Permeable pavement and vegetated roofs are considered new impervious surface for
purposes of determining whether the thresholds for application of minimum requirements are exceeded, as are lawns,
landscaping, sports fields, golf courses, and other areas that have modified runoff characteristics resulting from the
addition of underdrains designed to collect stormwater runoff. Open, uncovered retention/detention facilities shall
not be considered impervious surfaces for 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.
New pollution generating impervious surface (PGIS) means new impervious surface that is pollution-generating
impervious surface or any alteration of existing pollution-generating impervious surface that changes the type of
pollutants or results in increased pollution loads and/or concentrations.
On-site BMP means small scale drainage facility or feature that is part of a development site strategy to use processes
such as infiltration, dispersion storage evaporation, transpiration, forest retention, and reduced impervious surface
footprint to mimic pre-developed hydrology and minimize stormwater runoff.
RESIDENTIAL DRAINAGE APPLICATION (CONT ’D )

Pervious surface means any surface material that allows stormwater to infiltrate into the ground. Examples include lawn,
landscape, pasture, and native vegetation areas. Note for purposes of threshold determination and runoff volume
modeling for detention and treatment, vegetated roofs and permeable pavements are to be considered impervious
surfaces along with lawns, landscaping, sports fields, golf courses and other areas that have modified runoff
characteristics resulting from the addition of underdrains.
Pollution-generating impervious surface (PGIS) means an impervious surface considered to be a significant source of
pollutants in stormwater runoff. Such surfaces include those that are subject to vehicular use, industrial activities, or
storage of erodible or leachable materials, wastes, or chemicals and that receive direct rainfall or the run-on or blow-
in of rainfall. A covered parking area would be considered PGIS if runoff from uphill could regularly run through it or
if rainfall could regularly blow in and wet the pavement surface. Metal roofs are also considered PGIS unless they are
coated with an inert, non-leachable material (see Reference Section 11-E); or roofs that are exposed to the venting of
significant amounts of dusts, mists, or fumes from manufacturing, commercial, or other indoor activities. PGIS includes
vegetated roofs exposed to pesticides, fertilizers, or loss of soil. Other roofing types that may pose risk but are not
currently regulated are listed Reference Section 11-E. Lawns, landscaping, sports fields, golf courses, and other areas
that have modified runoff characteristics resulting from the addition of underdrains that have the pollution generating
characteristics described under the “pollution-generating pervious surface” definition are also considered PGIS.
Pollution-generating pervious surface (PGPS) means a non-impervious surface considered to be a significant source of
pollutants in surface and storm water runoff. Such surfaces include those that are subject to vehicular use, industrial
activities, storage of erodible or leachable materials, wastes, or chemicals, and that receive direct rainfall or the run-
on or blow-in of rainfall; or subject to use of pesticides and fertilizers, or loss of soil. Such surfaces include, but are not
limited to, the lawn and landscaped areas of residential, commercial, and industrial sites or land uses, golf courses,
parks, sports fields (natural and artificial turf), cemeteries, and grassed modular grid pavement.
Replaced impervious surface means any existing impervious surface on the project site that is proposed to be removed
and re-established as impervious surface, excluding impervious surface removed for the sole purpose of installing
utilities or performing maintenance on underground infrastructure. For structures, removed means the removal of
buildings down to the foundation. For other impervious surfaces, removed means the removal down to base course
or bare soil. For purposes of this definition, base course is the layer of crushed rock that typically underlies an asphalt
or concrete pavement. It does not include the removal of pavement material through grinding or other surface
modification unless the entire layer of PCC or AC is removed. Replaced impervious surface also includes impervious
surface that is moved from one location to another on the project site where the following two conditions are met:
(A) runoff characteristics and volumes remain the same or are improved in the area where the existing impervious
surface is removed , and (B) impervious surface at the new location is either designated as non-pollution generating
or the pollution generating characteristics remain unchanged compared to that of the original location.
Replaced pollution generating impervious surface (PGIS) means replaced impervious surface that is pollution-generating
impervious surface.
