Date: Thursday, May 2, 2024

Time: 3-4PM

Location: 90th Place S.E. & 89th Place S.E., Mercer Island

Event Purpose

Grinding and paving of the road at the bottom of 90th Pl S.E. is planned for May 28 and 29. Paving activities are very impactful to neighbors since there is limited access to the cul-de-sac and the work includes driveway approaches. This neighborhood conversation allowed the project team to share information with neighbors about what to expect during the paving process.

Date: Tuesday, September 28, 2023
Time: 4:30PM-5:30PM
Location: 90th Place Southeast, Mercer Island, WA, 98040

Event purpose

Construction on 90th Place Southeast has been progressing for over a year. Paving on 10/4 and 10/5 is an important milestone because it must be completed after all pipe installation and underground construction is complete.

Additionally, paving activities are very impactful to neighbors since there is limited access to the cul-de-sac and the work includes driveway approaches. This neighborhood conversation allowed the project team to share information with neighbors about what to expect during the paving process as well as highlight the reduction in construction activities after paving is complete.
