The existing structures on the site meet current setback requirements. A redesign and r reconstruction of the parking areas for the bowling facility on lot 1 will be completed 1 prior to final approval. Landscaping for the new bowling parking area and frontage landscaping for the existing auto sales lot on lot 2 will be provided prior to final approval. A detailed landscaping plan which shows planting types, sizes and locations in addition to any required on -site water treatment/detention facilities must be approved by the City prior to installation of the required landscaping. E. Natural Environment - Evaluation of the impacts and provision for mitigation of all impacts on all elements of the natural environment including topography, vegetation, soils, geology and all environmental issues as defined in the State Environmental Policy Act, WAC 197.11 and Section 18.24 of the Subdivision Code. Finding: A previous SEPA review was conducted for the proposal and a Revised Mitigated Determination of Non -Significance (a87-90) issued on January 15, 1992. The subject property has some small wetland areas located on proposed lot 3 as well as some drainage ways. An environmental assessment of these areas was performed by Shockey/Brent Associates and by the City's Planning Department which concluded that these features are non -regulated under Section 37 of the City's Zoning Code. Any new development of lot 2 or 3 will be subject to new application for SEPA review. Conclusion: No significant adverse impacts on the natural environment are anticipated as a result of the proposed short subdivision. No new mitigation of adverse impacts by SEPA conditions are being required for the proposal. Compliance with all applicable mitigation of adverse impacts by SEPA conditions of SEPA MDNS k87-90 are required. F. Drainage - Evaluation of all drainage impacts and provisions made for mitigation of all drainage impacts as defined in the City's Comprehensive Drainage Ordinance and Section 18.24 of the Subdivision Code. Finding: The subject property is located in the Swamp Creek Drainage Basin. Detention of stormwater runoff from lot 1 is required per City standards to control the additional runoff which will result from the improvements on lot 1. Stormwater runoff from the additional pavement on lot 1 must be treated in accordance with current City standards, prior to discharge of the stormwater from the site or to a stream or wetland. The meet the City's redevelopment standards, the stromwater treatment facilities must also be designed and sized to receive runoff from as much of the existing pavement on lot 1 as is practically achievable, or a separate sysk:m, such as a biofiltration swale, can be located and designed to receive runoff from existing areas. The preferred options for stromwater treatment are: 1) an infiltration basin, if suitable soils exist on the site; 2) a wetpond; 3) or a constructed wetland. All stormwater facilities must be designed in accordance with City standards. If non of the above stormwater treatment options are feasible, in the opinion of the City's Public Works Department, a biofiltration swale per City standards will be required to treat stormwater runoff.
