Supplemental Agreement #1 These revisions are necessary in order to improve drainage patterns and ease of maintenance for the trail. Change Order #2 The existing 73" Arch pipe is significant in size and appears to be sized for the 100-year event. However, the the original Storm Water Management plan for the Ramsey Town Center lacks a narrative and is not easy to interpret. Several things have changed since the original storm water management plan has been prepared, which may warrant a more in-depth analysis of the overall storm water system in the COR. This pipe is not necessitated by the Sunwood / Armstrong project. It is more closely related to the North Commons project and the restrictions that currently exist on the open space. If completed, this storm sewer pipe will receive runoff from areas in addition to the North Commons project. Connexus Cabinet Relocation Charges The location of the cabinet will obscure the proposed development sign for the COR TWO as indicated by the Development Manager. If there is no alternative sites for the sign, the only alternative is to relocate the cabinet. Funding Source: The funding source for Supplemental Agreement #1 and the Connexus relocation charges would be from the project budget, and a request should be made to Connexus to reimburse costs commensurate with their responsibility for the error. The funding source of Change Order #2 would be from the HRA and storm drainage fund. Staff Recommendation: We recommend approval of Supplemental Agreement #1. We recommend further review and analysis of Change Order #2 by City staff and the Development Manager. We recommend approval of relocating the Connexus cabinet. Committee Action: Motion to reccomend approval of Supplemental Agreement #1. Motion to recommend that further analysis be performed to evaluate the contemplated development patterns in the overall drainage area, associated runoff rates and volumes, and required storm sewer pipe sizes. Motion to reccomend relocation of the Connexus cabinet and a request be made to Connexus for the appropriate level of reimbursement of cost.
