• Removal of 4 trees • Root Impact of 10 trees • Avoided Impact to 25 trees in the boulevard area • PACT / Church Boulevard Impacts o No tree removals noted o Root Impact of 15 trees in the boulevard area • Existing Properties on south side of 161st Avenue o Higher driveway and grading impacts due to curb and gutter in the existing boulevard area o No tree removals noted o Anticipated moderate root impact to numerous trees along the corridor • Depending on ability to match grading Alternative 5: No Addition of Bicycle and Pedestrian Facilities . 28-foot wide road (12' travel lanes, 2' curb reactions) o Generally minimal impacts to trees along the corridor Timeframe: Staff estimates up to 15 minutes will be needed to present this case and respond to questions. Observations/Alternatives: Observation: All alternatives which include an off-street trail will have a significant impact to the existing trees in Central Park. The option of on -street bike lanes does impact a number of existing trees, but significantly fewer; however, the on -street bike lanes is not the optimal solution for pedestrians. Additionally, if trees are removed, Staff would like input if tree replacement and/or landscaping should be included as part of these improvements. The alternatives listed do not anticipate significant impacts to trees on the south side of 161st Avenue, which includes 9 properties, 7 of which are heavily wooded along the right of way. It should be noted tree removal will be required within the 20-foot wide drainage & utility easement between 7852 and 7826 161 st Avenue to accommodate storm sewer improvements. Additional tree removal may be required due to grading requirements in the ponding area in the rear yard of 7826 161 st Avenue and 7833 159 th Lane. Funding Source: Funding for 161 st Avenue reconstruction and any trail construction is proposed to come from MSA Funds. Storm sewer improvements are proposed to be funded from Stormwater Utility Funds and/or MSA Funds. Recommendation: Staff recommends Alternative #1 — reconstructing 161st Avenue as a minimum width 2 lane road with a 6-foot boulevard and 10-foot bituminous trail on the north side. Action: Motion to accept one of the identified alternatives, or reject all alternatives and provide alternative direction. 23-01 Street Summary 161 st Avenue CIP Sheet Bit Trail - Alt 1 Attachments Form Review Inbox Reviewed By Date
