NORTH PARK ROAD IMPROVEMENTS – JAMES WATTERS The new detour route to Robert’s Ferry was put up on March 3rd and North Park Road was closed to traffic on March 9th. Construction resumed later the same week. In early May, Boomerang mobilized off-site and has not yet turned. Access for homeowners at 300 North Park Road has been established and contact information has been provided to them. Their access will be maintained throughout the remainder of the project and changes will be communicated promptly. Phase 2 utilities are complete (aside from bus loop storm runs which cannot be completed until school is out). The Contractor has indicated their grading crew is not currently able to return to site and will return when they can. Paving is tentatively planned for May or June. Boomerang plans to pave the sidewalk and trail before they begin road paving. Coordination between the North Park Road project and the Homemakers site is ongoing. A Change Order for a temporary pipe connection to the Homemaker’s detention basin and Payment Application #13 has been submitted for Council approval the week of June 2nd.
