Intent. The intent af the regulation of bulk storage facilities is to allow such facilities in a location and manner so they are compatible with adjacent properties and benefici �l to the City and in accordance with the State Enviranmentai Poiicy Act . It is further the intent to insure that the safety , health , welfare , aesthetics and morals of the Community are maintained at a h3gh 1eve1 . Due to the unique characteristics and problems inherent in making bulk storage facilities compati �le with surrounding praperties and environment , the City Council finds that special review of bulk storage facilities is required to insure the intent of these regulations ; and the City Gouncil expressly finds that in the Green River Valley , City af Renton and surrounding areas there has been a ioss in air quality and that a patential exists for a continuing deteriaratian in this air quality due in part t4 the unique meteorological and topographic characteristics such as the channeling and holding of air masses by inversions and the surrounding hills . This degradation in air quality adversely affects the liveabiiity and desirability of the City and is injurious to the health and well -being of its citizens . ThOS2 USeS cTassified dS d recognized higher risk have higher standards applied to them including , �ut not limited to , Landscaping , Traffic and Access and Hazardous Materials . Ihese regulations are to supplement and be in additian to existing ardinances and code provisians . 2 . Special Permit and Administration . l . Bulk storage facilities may be allowed on�y by special permit as specified in Sectian 4-722 ( B ) . The fee for the special permit for bulk storage facilities shail be the basic fee plus ten ( 10) dollars for each acre or fraction thereof . 2 . The Planning Commission is designated as the official agency of the City for the conduct of public hearings ; and the Plannina Department is responsible for the general administration and coordination . The Planning Department shail establish administrative procedures , which sha13 include , but are not iimited ta : prepara- tian of application farms ; determining campleteness and acceptance of application ; and estab] ishment of interdepartmental review rauting procedures . � � � 3. The responsibility of producing information and data � ' to establish that the proposed bu7k storage facility complies with the standards setforth in this section shall be on the applicant . 4 . The Planning Department shall be responsible for deter- mining whether an application is a bu� k storage facility as defined herein . Such decision may be appeaied to the City Council within ten ( IO ) calendar days after such determination upon proper written notice filed with the City Council . 3 . Height . The maximum height of all stor�ge containers and stock piles of bulk materials and/or products shall be forty (40 ) feet or that of the structure height of the underlying zone if more restrictive . The storage of bulk materials in containers above manufacturing plants shall not be considered as bulk storage , but shall be classified as part of the supporting structure . No roof shall extend beyond five ( 5 ) percent slopes drawn from forty (40 ) foot high vertical surfaces contiguous to the base of th� structure . Only accessory items such as , but not limited to : antennas , ladders , light fixtures , railings , vent pipes and safety or health related items sha11 be excluded from the determina- tion of structure height . 4 . Setbacks . All structures and bulk storage , except security fences , opaque screens and signs shall be located at least sixty (60 ) feet from all public right�of-ways , .vildlife habitat , public areas , parks and waterways which include , but is not limited to rivers , lakes , streams and drainage channels . In all other instances the setbacks shall be at least twenty ( 20 ) feet from the property line . 5 . Landscaping and Screening . The intent of landscaping and screening is to minimize the visual impact of bulk storage as viewed from adjacent or nearby properties or facilities and to enhance the image of the industrial areas and the City . 1 . Recogni zed Hi gher Ri sk Storage . Those bulk storage uses which are considered as having d recognized higher risx shall have a barrier as specified in Section 4-734 . 15 , Hazardous Materials , with a screen that is at � east eighty (80 ) percent opaque on top of the barrier and setback at least twenty ( 20 ) feet from the property line . The barrier shall have a maximum height of four (4 ) feet when measured as in §4-734 . 15 . 3 . The combined height of the four-foot (maximum) barrier arad screen shall be at least twenty-five ( 25 ) percent of the height of the bulk storage provided such combination is at least six ( 6 ) feet high . An optional security fence shall have at least a twenty ( 20 ) foot setback . All areas between the property lines and the screen shall be landscaped except for ingress and egress areas and except when a second bulk storage faci,lity has a contiguous side or rear property line with an existing bulk storage facility constructed to the standards specified in Section 4-734. The landscape plan shall be prepared by d licensed landscape architect and approved by the Planning Oepartment . 2 . Other Bulk Storage . Those bulk storage uses not included in Section 4-734 . 5 . 1 above shall have a screen including gates and shall be at least eighty (80 ) percent opaque surrounding the property area . Said screen shall be at least twenty-five ( 25 ) percent as high as the bulk storage containers or stock piles provided said screen is at least five ( 5 ) feet high . The screen and optional security fence shall be setback at least twenty ( 20 ) feet from all property lines except that for those bulk storage facilities whose total ownership is less than two and one-half ( 2Z) contiguous acres in area , the Planning Department may reduce this setback up to fifty ( 50 ) percent for good cause and upon proper written application . Al1 areas between the property -2- ' lines and the screen shall be landscaped except for ingress and egress areas and except when a secand . • bulk storage facility has a co�tiguous side or rear property iine that abuts an existing bulk storage facility constructed to the standards specified in Section 4-734 provided there is at least a twenty (20 ) foot landscaped strip . The landscape plan is to be approved by the Planning Department . A land- scaped berm may b� used by itself or in combination with a screen provided the required height is met . The slopes of said berm shall be at least two ( 2 ) feet horizontal to one ( 1 ) foot vertical . There shall be a flat area on top of the berm with a minimum width of two (2 ) feet. A retaining wall may be substi - tuted for the internal side of the berm provided the retaining wall is approved by d licensed engineer . 3 . Landscaping Maintenance . The maintenance of landscaping shall be assured prior to the issuance of a building permit by requiring one of the following four options ; (a ) the posting of a performance bond for one hundred fift.y ( 150 ) percent of the estimated cost of main- tenance of landscaping for a three ( 3 ) year period , ( b ) the depositing with the City Clerk of a certified or cashier ' s check for one hundred fifty ( 150) percent of the estimated cost of maintenance of landscaping for a three (3 ) year period , (c ) filing with the City Clerk a copy of a service contract for maintenance of landscaping for a three ( 3 ) year period , or (d ) such other written commitments that will assure satis- factory maintenance of landscaping for a three (3 ) year period . Any of the four ( 4 ) options above are to be approved as to legal form prior to acceptance by the City. Landscaping is to be maintained in a healthy , neat manner and shall be subject to periodic inspection by the City. 6 . Signs . The only identification signs permitted shall be one ( 1 ) sign per street frontage that shall be four (4 ) feet in height or less , with a maximum of two ( 2 ) faces and no more than thirty ( 30 ) square feet per face . Such signs may be illuminated by external lights . Exit and entrance signs four (4 ) square feet in area or less may be placed at street entrances . 7 . Locational Criteria . The Planning Commission shall review the impact of the proposed use to determine whether it is compatible with the proposed site and general area . The Planning Commission may require any applicable Bulk Standard to be up to fifty ( 50 ) percent more strict than specified to alleviate a potential problem , providing it shall be shown : l . That because of special circumstances applicable to subject property , including size , topography , location or surroundings and special characteristics applicable to subject facilities including height , surface drainage , toxic substances , traffic and access , sound , liquid waste , light and glare , odorants , flammable and explosive materials and gaseous wastes , the strict application of. the Zoning Code and Bulk Storage Regulations is found to deprive neighboring properties of rights and privileges enjoyed by other properties in the vicinity and under identical zone classification ; 2 . That the application of more strict standards will not be materially detrimental to the subject facility and will maintain the full rights , privileges and environment of neighboring properties . 3 . That the application of such modifications shall be supported by documented evidence of a clear and compelling nature to justify such stricter standards . In the case of hardships affecting the subject property , variances to these Bulk Standards may be granted by the Planninq Commission subject to th� conditions of Section 4-731 (C� ( B ) . -3- Figure 4-734.5-1(a) LANDSCAPED BERM ::::t7CV�I�N(�::::::: ::::�� : �1ApaCIMVM • : H�- ' :: �� ' z;MtN�N�UM 1 W c�T�P � 2:1 �st�P� 2�I�f� �T ::............................................... . � S�pE Q�V S►OL �tic,�E �F R�c�tT—aF�w�'t � R��►� �t't.�= CITY OF RENTON - PL/►NNING DfPARTMEM , Figure 4-734.5-1(b) � LANDSCAPEO BERM AND OPAQUE SCREEN ' i . . ,_ � :::::::::::....................................... :�::�v�oR�T : :::spa�� :� NIq1VM�N1 ............................... :: HEt�tt�' ::::::::::�:::::::::::::::::::::::::::::::::::::: �, � �' auf�' �'+�f�c'F ::::::::::::::::::�:�::::::::::::�:::::::::::: � ::::�:��::::��::�::::�::::::::..::::::�::::�:: �:::��::::::::::::::::::::::��:�::::::��::�:�� T�-�N�I�R .....................:...........:::::::::. . ::::::::::::�:::::::�:::::�::�:::�::::::�: ......:..............................:.... z�f��P w�� 2�� z:i �pc ��T ................. ......................... , - � . �� y� �R►" � �-�1 t�E � Rl�t�f'-�-vJp.�( � ' �uttc�D �[d�cK .

Liquid Waste . The intent of this Standard is to preserve and enhance the quality of the environmEnt and protect the public health and welfare by preventing the disposal of liquid industrial wastes by unacceptable methods and in unapproved areas . 1 . The d ; scharge of a� l waterless liquid waste shall be subject to the conditions of §4-734, 12 . 3 and/or disposed of by a liquid waste disposal compan� , 2 . The discharge af any water co�taining liquid , gas or solid wastes in solution and/or as a mixture into any part of the natural water system sha� l comply with the standards and compatibility requirements of the Washington State Department of Ecology or any successor department or agency th�reof . The administrative official shall be supplied with a true copy of any and all discharge permits issued to the facility by the State of Washington Departmer�t of Ecolagy. 3 . All wastes discharged into a se�erage system shall comply with the applicable regulations af the City of Renton and The Municipality of Metropolitan Seattle Sewerage System governing the control and disposal of industrial waste . 4 . All liquid wastes undisposable by treatment , after treatment , or by sewerage system shall be disposed of on a scheduled basis clearly related in both rate and magnitude with the industrial prnc�ss or source generating the waste . 5 . UpOn the request Of th2 a�manistrative official the industry shall provide substantial proof of having disposed of liquid waste , falling in the categories of §4-734 . 12 . 4 equal to or greater than eighty (80 ) percent in either volume or weight of the amount generated during the previous six ( 6 ) months of opera�ion . Should the generation of such liquid waste be on a sporadic basis then the industry shall provide the administrative official with written evidence of substantial compliance witn this subsection . 6 . The release of odorants or gaseous wastes from liquid wastes awaiting disposal shall be prevented by using adequate means of storage and all other reasonable means necessary . 7 . Any treatment of liquid waste solely for the purpose of disposal shall be permitted whe� thegeneration of any solid or gaseous wastes is adequately handled in com- pliance with these Standards and all other rules and regulations of state and regional agencies . Such treat- ment shall employ the best practicable control currently available to industry . Liquid waste shall include surface runoff waters as per Section 4-734 . 8 when contaminated with chemicals , oils or other toxic substances . 13 . Light and Glare . The intent of this Standard is to afford the public the safety of adequate lighting while avoiding unnecessary glare and exposure to excessive outdoor illumina- tion which may create a hazard or unreasonably interfere with the relaxation and enjoyment of public open spaces , right-of-ways , and normal residential activities and pursuits . l . Illumination levels shall be measured with a photoelectric photometer ( light-meter ) hav� ng a spectral response similar to that of the human eye , following the standard spectral luminous efficiency curve adopted by the International Commission of Illumination . 2 . The illumination from all sources located on a lot shall have the maximum value of eleven ( 11 ) lumens per square meter outside of lot lines and six (6 ) lumens per square meter outside the district line . In all cases of confilict the aistr�.ct Zine value shall apply . - 12- 3 . The intrinsic brightness of any source visible beyond the district lines shall have a maximum value of fifty (50) candles per square centimeter . � 4 . Intermittent , rotating or f� ashing lights of an intrinsic brightness greater t.han two (2 ) candles per square centimeter and with a frequency greater than once in any five (5 ) second time period shall not be visible beyond district lines unless for the sole purpose of alarm or giving warning . 14 . Odorants . The intent of this Standard is to prevent the occurrence of certain offensive odors in the environment by limiting the concentration of chemical compounds which are known to produce strong olfactory responses . This Standard does not attempt to determine the intrinsic or subjective good or bad qualities of an odor , but only that the concentration of specific constituent compounds are above adopted values which have been accepted for the health and well being of the general public . 1 . The concentration of specific compounds listed in Schedule 4-734. 14- 1 shall not exceed the oaor threshold values in two consecutive air samples . Three air samples are to be taken over a two (2 ) hour period , one sample each at the beginning and end of the test period and one sample near the time midway through the sample period . The administrative officiaz may establish the time of the sample period . 2 . The location for taking the three samples shall remain fixed during the test period and shall be at a point outside lot lines , at ground level or habitable eleva- tions and a safe and reasonable place consistent with the location of the reported violation . 3 . Monitoring shall be undertaken only upon receipt of a complaint made by a person who resides , owns property , or is employed in the area affected by the complained of odors , unless the area is designated as a public use area whereupon all complaints will be accepted . 4. When more than one concentration is listed for a substance in these Standards , the more stringent shall apply . 5 . The samples shall be taken by d qualified person and the concentrations of odorants shall be measured in a certified laboratory or facility at the request of the administrative official . 6 . Nothing in this Standard shall be construed to impair any cause of action or legal remedy therefor of any person , or the public for injury or damages arising from the emission of any odorant in such place , manner or concentration as to constitute air pollution or a common law nuisance . 15 . Hazardous Materials . The intent of this Standard is to provide adequate separation between highly flammable or explosive materials used in industries of d recognized higher risk and the neighboring properties and public areas , total containment of all hiqhly flammable , toxic and polluting liquid materials , limits for the stored quantity of highly flammable and explosive materials as a function of property area , and all other reasonable safety measures deemed necessary for the protection of people , property , and the environment from the threat and destruction of fire and/or explosion , and to prevent encumbering adjoining properties with burdens which are related to the hazards of highly flammable and explosive materials . 1 . An industry shall not impose economic burdens such as , but not limited to higher insurance rates and/or operational limitations upon neighboring facilities due to its location and hazardous nature .
