Any Exterior mechanical equipment shall be has been <br />screened per ordinance. <br /> <br />Grading Plan and Stormwater Management <br /> <br />Per the City Engineer Memo dated October 1, 2025: <br /> <br />Stormwater management for 7920 Lake Drive site consists of constructing infiltration basins on <br />the east and west sides of the site. <br /> <br />Pre- and Post- Development Discharge Rates (cfs) <br />Condition 2-Year 10-Year 100-Year 10-Day Snowmelt <br />Existing* 0.84 1.81 5.21 Not required <br />Proposed 0.78 1.55 5.43 Not required <br /> <br />Additional comments/revisions are noted in the attached City Engineer memo. <br /> <br />An additional drainage and utility easement is required for the infiltration basin. This easement <br />will be dedicated and recorded by a separate document. <br /> <br />Public Utilities <br /> <br />The commercial building will be municipally served by an 8” sanitary sewer main and 12” <br />watermain along Kelly Street. <br /> <br />Tree Preservation, Mitigation Standards and Landscaping <br /> <br />Per the September 24, 2025 Environmental Board staff report: <br /> <br />A tree preservation plan was required for this project. There are 17 existing onsite trees, as part <br />of the project 4 will be removed. The 4 trees to be removed are within the Basic Use Area and <br />do not require replacement. <br /> <br />Foundation landscaping requirement are 2 large trees + 4 large shrubs per 100lf of building <br />facing public roads. The site has 403 lf of foundation frontage requiring 8 trees and 24 shrubs. <br /> <br />The plans show 25 shrubs meeting the requirements but only 2 large trees (4 medium trees) <br />being proposed. Based on the design of the building with office frontage and doors to the <br />sidewalk, additional tree planting is not feasible. City Code section 1007.049 4(d) states the city <br />may allow flexible planting locations where service areas or other constraints make the <br />standards difficult to meet. Staff believe this is the case in this situation. <br />Page 10 of 406
