Based on analysis of probable impacts from the proposal,staff recommends that the Responsible Officials make the following Environmental Determination: DETERMINATION OF NON-SIGNIFICANCE Issue DNS with 14 day Appeal Period.XX DETERMINATION OF NON -SIGNIFICANCE -MITIGATED. Issue DNS-M with 14 day Appeal Period. Issue DNS-M with 15 day Comment Period followed by a 14 day Appeal Period. MITIGATION MEASURES . . . . The project will be required to comply with the Department of Ecology Stormwater Management Manual for erosion and sedimentation control. The project will be required to comply with the 2005 King County Surface Water Design Manual for surface water management. The applicant shall pay the appropriate Traffic Mitigation Fee based on $75.00 per new average daily trip attributed to the project prior to the issuance of building permits. The applicant shall pay the appropriate Fire Mitigation Fee based on a rate of $0.52 per square foot of new for each dwelling unit prior to the issuance of building permits. D.ENVIRONMENTAL IMPACTS In compliance with RCW 43.21 C.240,the following project environmental rewew addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. 1.Earth Impacts:The subject site is relatively flat with an approximate slope of 2.5%from west to east.A 4-6 foot high bank exists along the western property line of the subject site.The site is currently improved with an existing 7,329 square foot church and detached associated outbuildings and is vegetated with a lawn,ornamental landscaping,and a total of 33 trees (17 deciduous and 16 conifer),The proposed addition would expand the existing footprint of the church to the east and to the west.The estimated percentage of impervious surfaces after project construction is 75%. The proposal is to construct the church addition in two phases.The first phase would include the expansion of the existing parking lot to a total of 102 spaces and the construction of 6,083 square feet to the first floor of the church.The second phase would include a two-stow addition totaling 8,714 square feet in area.The proposed development would also provide required landscaping. Due to the potential for erosion and sedimentation problems resulting from the dirt work required for the construction of the proposed townhomes,the staff recommends a mitigation measure requiring the applicant to comply with the Department of Ecology's Stormwater Management Manual for erosion and sedimentation control. ercrpt_05-162 RentonBibleChurch.doc City of Renton P/B/PW Department Renton Bible Church Addition Environ•l Review Committee Staff Report •-05-162,CU-H,V-H,SA-H,ECF REPORT AND DECISION OF January 31,2006 Page 3 of 3 Miti.qation Measures: 1.The project shall be required to comply with the Department Management Manual for erosion and sedimentation control. of Ecology's Stormwater Policy Nexus:SEPA Environmental Regulations;DOE Stormwater Management Manual 2.Air and Noise Impacts:During project construction,on-site emissions will consist of fugitive dust and emissions from construction equipment.These impacts are anticipated to be minor and largely confined near the site. Vehicular emissions are regulated by the State of Washington and Puget Sound Clean Air Agency. Therefore staff does not recommend any additional measures. r Short-term noise from construction equipment would occur between 7:00 AM and 5:00 PM.The equipment and construction of this project will be required to meet federal,state,•and local emissions and noise requirements;therefore no further mitigation is recommended. Miti.qation Measures:No further mitigation is recommended. Policy Nexus:N/A 3.Water -Stormwater Impacts:A Technical Information Report prepared by Baseline Engineering,Inc.dated October 21,2005 was submitted with the project application.According to the report the existing surface water runoff from the existing church flows to the east and into the Union Avenue NE stormwater conveyance system.The paved driveway and parking areas are proposed to be graded such that stormwater runoff will flow into catch basins.The runoff will then be conveyed through a Stormwater Management Storm Filter Vault for water quality and then into a detention tank that controls the flow leaving the site.The tank would release runoff intothe storm system within Union Avenue NE. Staff from the City's Plan Review Section have reviewed the drainage report.The subject site is located within the May Creek Drainage Basin.Due to the sensitivity of the May Creek Drainage Basin,staff recommends a mitigation measure requiring the project to comply with the 2005 King County Surface Water Design Manual. Mitigation Measures:The project shall be required to comply with the 2005 King County Surface Water Design Manual for stormwater runoff management. Nexus:SEPA Environmental Regulations;2005 King County Surface Water Design Manual 4.Transportation .... Impacts:The proposed addition is expected to add additional vehicle trips to the street system. Therefore,the applicant will be required to pay a Traffic Mitigation Fee of $75.00 per new average daily trip attributed to the project prior to the issuance of building permits.Approximately 55.416 average daily trips would be generated by Phase I of the proposed project and 79.385 average daily trips would be generated by Phase II of the proposed project.Therefore,the applicant will be required to pay a $4,156.21 traffic mitigation fee (55.416 trips x $75 =$4,156.21)for Phase I and a $5,953.84 traffic mitigation fee (79.385 trips x $75 =$5,953.84)for Phase II resulting in a total traffic mitigation fee of $10,110.05.= Mitigation Measures:The applicant shall pay the appropriate Traffic Mitigation Fee based on $75.00 per new averagedaily trip attributed to the project prior to the issuance of building permits. ercrpt_05-162 RentonBibleChurch.doc City of Renton P/B/PW Department • Renton Bible Church Addition Environ•l Review Committee Staff Report •-o5-162,CU-H,V-H,SA-H,ECF REPORT AND DECISION OF January 31,2006 Page 4 of 4 Nexus:SEPA Environmental Regulations,Traffic Mitigation Fee Resolution No.3100,Ordinance 4527 5.Fire /Emergency Services Impacts:Fire Prevention staff indicated that sufficient resources exist to furnish services to the proposed development,subject to the condition that the applicant provide required improvements and fees.
