14 . 06 . 010 Findings
Each year tons of sediment deposits are washed and blown from land - disturbing activities . These
sediment deposits bring about detrimental effects to our society in the following ways :
A . Excessive input of sediment deposits in local stormwater collection and conveyance
systems reduces their capacity to contain and convey water and increase the
likelihood of flooding .
B . Sediment deposits in local storm drainage systems cause an increase in public
expenditures for maintenance ;
C . Sediment deposits in stormwater facilities increase home owners association ' s
expenditures for maintenance ;
ic expenditures for cleaning and maintaining roadway surfaces that
D . Increased publ
receive excessive sediment ;
E . Excessive sediment deposits can cause damage to occur to adjacent properties and
rights - of- way ;
F . Damages occur to fisheries due to the input of sediment deposits which clog
spawning beds and increase turbidity levels , impairing the feeding ability of aquatic
animals ;
G . Runoff of sediment deposits promotes the transport of nutrients to lakes , causing
algal blooms and oxygen depletion ; and
H . Sediment deposits have been found to cause detrimental water quality problems in
the Washougal River , Lacamas Creek , Lacamas Lake , Round Lake , Fallen Leaf Lake
and , ultimately , impacts the water quality in the Columbia River .
14 . 06 . 020 Definitions
" BMP " means Best Management Practice , which is the schedules of activities , prohibitions of
practices , maintenance procedures , and structural and/or managerial practices , that when used

Manual .
" Director " means the City of Camas public works director , or designee .
" Impervious surface " means a hard surface area that either prevents or retards the entry of water
into the soil mantle as under natural conditions prior to development ; a hard 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 , roof tops , walkways , patios , driveways , parking lots or storage
areas , concrete or asphalt paving , gravel roads , packed earthen materials , and oiled , macadam or
other surfaces which similarly impede the natural infiltration of stormwater . Open , uncovered
retention/ detention facilities shall not be considered as 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 .
" Land - disturbing activity " means any activity that results in a change in the existing soil cover
(both vegetative and non - vegetative ) or existing soil topography , including , but not limited to ,
demolition , construction , reconstruction , clearing , grading , filling , excavation and landscaping .
" New development " means land- disturbing activities , including Class IV General Forest
Practices that are conversions from timber land to other uses ; structural development , including
construction or installation of a building or other structure ; the creation of impervious surfaces ;
and any subdivision , short plat and binding site plans , as defined in RCW Chapter 58 . 17 . All
other forest practices and commercial agriculture activities are not considered new development .
" Project site " means that portion of a property , properties , or right of way subject to land

activity ; and land - disturbing activities associated with structural or impervious redevelopment .
" Small parcel " means any development project which involves land - disturbing activities of less
than one acre and adds less than five thousand square feet of impervious surface .
" Stormwater Collection and Conveyance System" means the drainage facilities , both natural and
man - made , which collect , contain , and provide for the flow of surface and stormwater to a
receiving water or infiltration facility . The natural elements of the conveyance system include ,
but are not limited to , small drainage courses , streams , rivers , lakes , and wetlands . The human -
made elements of the collection and conveyance system include , but are not limited to , gutters ,
inlets , ditches , pipes , channels , and retention/detention facilities .
