I.Pipe not ava.ilable over 12-inch diameter. m.Slip form lining is available in 6-inch through 50-inch diameter for almost any pressure,if sufficient pipe cross-sectional area is available. n.Pressure grouts and gels are not acceptable for rehabilitation or patching of storm and sanitary sewers. 55 ORDINANCE NO.4851 o.SUitabjlity of pipe lining and gasket material to resi$t chemical attack by conveyed fluids must be determined for each pipeline sefvice considered. p.All storm and sanitary sewer manholes,catch basins,and inlets should be equipped with precast concrete bottom and sidewalls with rubber gasketed joints between sections,water-tight epoxy grout or other approved pipe entrances through walls,and approved waterproof coating of all interior floor and wall surfaces.Manholes,catch basins.and inlets should have no leakage when hydrostatically tested at atmospheric pressure. Q.Has Qood resistance to a number of chemicals,oetroleum oroducts,and hydrooen sulfide corrosion. r."Zero leakage"test requirement may be impossible to achieve under the best conditions for any pipe materials because trapped air may distort test results,even in a drop-tight pipe.Pressure and leakage test requirements should consider whether the pipe has steel slope or will stand full of liquid.Pipelines should be tested wlth the intent to prevent or minimize leakage.Air testing should not be allowed;hydrostatic testing should be as stringent as any found in the .industry. Pipe materials,without regard for chemical attack,corrosion,or puncture,are generally ranked as follows,in decreasing order!?f liquid-tight reliability:·welded steel with welded joints·PVC with solvent welded joints·slip form liner·ductile iron with viton or rubber gaskets .·welded steel with rubber gasketed joints·PVC with viton or rubber gasketed joints s.Joints should consist of "heat-shrink"wrap,standard corrugated coupling,and fuil pipe band clamps. I.The use of PVC may be restricted by other Department policy in regards to depth of pipe cover. u.HOPE may be adversely affected by solvents;its use is not recommended where contact with solvents may occur. 56 I I I f· I ORDINANCE NO.4851 .SECTION XXIV.Section 4-4-030.B of Chapter 4,Property Development Standards, of Title IV,Development Regulations,of Ordinance No.4260 entitled "Code of General Ordinances of the City of Renton,Washington"is hereby amended to read as follows: B.ADOPTION BY REFERENCE: The goals,objectives and policies as set forth in the following are presently in force or as modified from time to time are hereby incorporated by reference and shall be considered as if fully set forth herein: Cedar River Master Plan (1976) Comprehensive Solid Waste Management Plan (1983) Green River Valley Plan (1984)...

(2)Generally,the only condition under which a variance from the elevation standard may be issued is for new construction and substantial improvements to be erected on a lot of one-half (1/2)acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level,provided criteria in RMC 4-9-250.B.8.b(I)have been fully considered. 80 ORDINANCE NO.4851 As the lot size increases the technical justification required for issuing the variance increases. (3)Variances may be issued for nonresidential buildings in very limited circumstances to allow a lesser degree of floodproofing than watertight or dry- floodproofmg,where it can be determined that such action will have low damage potential,complies with all other variance criteria except RMC 4-9- 250.B.8.b(2),(3)or (4),and otherwise complies with RMC 4-3-050.1.2.a.and b.of the General Standards. (4)Variances may be issued for the reconstruction,rehabilitation,or restoration of structures listed in the National Register of Historic Places or the State Inventory of Historic Places,without regard to the procedures set forth in this section. (5)Variances shall not be issued within a designated floodway if any increase in flood levels during the base flood discharge would result. (6)Variances shall only be issued upon: • A showing of good and sufficient cause; • A determination that failure to grant the variance would result in exceptional hardship to the applicant; • A determination that the granting of a variance will not result in increased flood heights,additional threats to public safety,extraordinary public expense, create nuisances,cause fraud on or victimization of the public or conflict with existing local laws or ordinances. • A determination that the variance is the minimum necessary,considering the flood hazard,to afford relief. c.Conditions f,>f Approval:Upon consideration of the factors of RMC 4-9-250.B.8.b. above,and the purposes of this section,the Hearing Examiner may attach such conditions to the granting of variances as it deems necessary to further t~e purposes of this section. d.Notice Required Upon Variance Approval:Any applicant to whom a variance is granted shall be given written notice that the structure will be permitted to be built with a lowest -floor elevation below the base flood elevation and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation e.Records:The Department Administrator or hislher designee,the Building Official shall maintain the records of all variance actions and report any variances to the Federal Insurance Administration upon request. 9.Special Review Criteria -Single Family Residence on a Legal Lot with a Category 3 Wetland:Tn lieu of the criteria shown in RMC 4-9-250.B.5 and 6,a variance may be granted from any wetland requirement in the Critical Areas Regulations for a single family residence to be located on an existing legal lot if all of the fQllowing criteria are met: 81 ORDINANCE NO.4851 .3.The proposal is the minimum necessary to accommodate the building footprint and access.In no case,however,shall the impervious surface exceed 5,000 square feet, including access.Otherwise the alteration shall be reviewed as a Hearing Examiner Variance and subject to the review criteria ofRMC 4-9-250.B.6;
