ORD 2256 ORDINANCE NO , AN ORDINANCE amending Section 15 . 32 of the Camas Municipal Code , to provide for erosion prevention and sediment control , adopting standards of review, provide for the submission of a final erosion prevention/ sediment control plan , and prescribing a penalty for violations . THE COUNCIL OF THE CITY OF CAMAS DO ORDAIN AS FOLLOWS : Section I Section 15 . 32 . 010 of the Camas Municipal Code is amended to provide as follows . 15 . 32 . 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 : 1 . Excessive input of sediment deposits in local storm drainage systems , stormwater facilities , ditches , creeks , and streams reduce their capacity to contain and convey water , thus increasing the likelihood of flooding . 2 . Sediment deposits in local storm drainage systems cause an increase in itures for maintenance . public expend 3 . Sediment deposits in stormwater facilities increase Home Owners Association ' s expenditures for maintenance . 4 . Increased public expenditures for cleaning and maintaining roadway surfaces that receive excessive sediment ; 5 . Excessive sediment deposits can cause damage to occur to adjacent properties and rights - of--way - 60 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 ; 7 . Runoff of sediment deposits promotes the transport of nutrients to lakes , . causing algal blooms and oxygen depletion ; and 8 . 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 . Section II Section 15 . 32 . 020 of the Camas Municipal Code is amended to provide as follows : 15 . 32 . 020 - Adoption of Standards The city council adopts the following documents , including all diagrams and text : " Erosion Control Plans , A Technical Guidance Handbook , City of Camas , Washington , August 26 , 1991 or latest edition ; " Stormwater Management in Washington State , Department of Ecology , August 1999 (Draft) or latest edition ; and "A Builders Guide to Erosion Prevention & Sediment Control , Second Edition , Clark County Home Builders Association , Vancouver , Washington .

Storm Drain Inlet Protection : All storm drain inlets shall be protected so that stormwater runoff shall not enter the conveyance system without first being filtered or otherwise treated to remove sediment . 7 . Storm Drain Outlet Protection : All storm drain outlet devices shall be protected so that stormwater runoff leaving a project site will flow at non- erosive rates . 8 . Maintenance : All erosion and sediment control BMP ' s shall be regularly inspected and maintained to ensure continued performance of their intended function . A maintenance log for private facilities shall be provided and kept as a permanent record . The maintenance log shall be in a designated on- site location . 9 . Idle Construction Sites .

BMP ' s damaged during construction shall be replaced or repaired . D . Individual Home Sites and Small Parcels a Ordinance No . Page 7 1 . Construction of home sites and small parcels can cause significant amounts of sediment to be transported to receiving waters . Care must be taken to stabilize base soil throughout the construction process . Vehicles must be limited to construction access points . Builders of single family homes and other small prof ects shall refer to the following BMP manuals for guidance in preparing a site erosion control and soil stabilization plan : a . " Stormwater Management in Washington State " , Department of Ecology , August 1999 (Draft) or latest edition , and b .

Workers ' personal vehicles shall be parked on adjacent streets or other approved areas . c . All unworked and exposed soils must be stabilized by seeding , covering , or mulching from the curb line to at least ten ( 10 ) feet from the building envelope . d . Pre - grade all sidewalk areas receiving runoff from the subject lot and stabilize for use as sediment traps . e . Gravel drives used as site entrances shall be constructed of minimum two - inch (2 " ) diameter gravel and no finer materials are allowed . f.

In non-work periods , inspections shall take place after each rainfall or at least once a week , whichever is more frequent . Needed corrections shall be made immediately . Section IX A new section 15 . 32 . 090 of the Camas Municipal Code is hereby added to provide as follows : 15 . 32 . 090 - Enforcement A . The severity of enforcement shall generally correspond to the degree of actual or 3 6 Ordinance No . Page 8 potential impact of erosion and sediment from a site on natural and man- made water bodies , adjacent property , stormwater conveyance systems , and stormwater facilities . The director of public works , or his authorized designee , is directed and authorized to implement and enforce all provisions of this chapter . In enforcing this chapter , the public works director shall have the following duties and powers : 1 ) To require the submission of erosion prevention/sediment control plans , and to review and approve such plans . 2 ) To inspect all construction activities to assure compliance with the provisions of this chapter . 3 ) To issue a " stop work" order for the site upon notice of any construction activity being conducted in violation of this chapter or in violation of an approved erosion prevention/ sediment control plan . 4 ) To require any person violating the provisions of this chapter or an approved erosion prevention/ sediment control plan to undertake all cleanup , corrective , and any other remedial measures necessary to remedy such violation . 130 Enforcement Stop Work Order a . The issuance of a " stop work" order indicates that all work of every type , make and description on the site shall cease , except for erosion prevention/sediment control measures . b . A " stop work" order will be in effect until such time as the Director establishes that all the necessary erosion prevention/ sediment control measures are in place , functioning , and the site is stabilized . c . Upon the written request of the person ordered to " stop work" , the Director may authorize the resumption of work on the site prior to completion of all directed mitigation efforts . The Director shall only authorize the resumption of work where the aggrieved person is actively pursuing directed mitigation efforts , the resumption of work will not create additional hazards , and the work will in no manner diminish the ability of the aggrieved person to finalize directed mitigation efforts . C . Enforcement Civil Infraction a . Any person, firm or corporation which violates any provision of this chapter or which undertakes any construction activity in violation of an approved erosion prevention/ sediment control plan as outlined in this chapter or who violates the terms of any " stop work" order issued pursuant to this chapter , shall be guilty of a civil infraction punishable by a fine of not more than five hundred dollars a day . Each separate day or any portion thereof during which any violation occurs or continues constitutes a separate offense . D . Continued Duty to Correct Violation . Payment of a monetary penalty pursuant to this Chapter does not relieve a person of the duty to correct the violation as ordered . E . Appeal . Any appeal to the decision of the Camas municipal court shall be governed by the Rules for Appeal of Decisions of Courts of Limited Jurisdiction (RALJ) * F . Accrual of Penalty . The City is authorized to collect the monetary penalty by use of appropriate legal remedies .
