AGENDA ITEM 5E STAFF ORIGINATOR: John Powell, City Engineer DATE: November 4, 1998 TOPIC: Resolution No. 98 -184, Consideration of Joint Powers Agreement with the Metropolitan Council, l -35E Area Projects BACKGROUND: The Metropolitan Council is proposing to install a new gravity trunk sanitary sewer, referred to as the Centerville Interceptor, along Cedar Street some time within the next two years. This sewer will carry flows from Centerville, Lino Lakes, and Hugo to the Forest Lake interceptor. The City's Otter Lake Road Improvements and the 21st Avenue Lift Station /Forcemain Improvements will be affected by the proposed sanitary sewer. The Otter Lake Road project involves the reconstruction of existing Otter Lake Road from 500 feet south of Cedar Street to Main Street. As we do not want the new roadway disturbed by the construction of the new sewer, we have included the installation of a steel casing pipe at Cedar Street in the Otter Lake Road contract for future use by the Metropolitan Council. This will allow them to install their sewer across Otter Lake Road without excavating the new roadway. The proposed Joint Powers Agreement (JPA) with the Metropolitan Council calls for them to reimburse the City for the full cost of the casing pipe and an additional 14% for engineering. The 21`t Avenue Lift Station/Forcemain project involves the installation of a new City sanitary sewer pumping station near the south leg of Northern Lights Boulevard to be platted as part of the Clearwater Creek Business Center located on the southwest corner of 1 -35E and Main Street. The pumping station will pump the sewage south along proposed 21st Avenue to Cedar Street then east along Cedar Street, under 1 -35E, to an existing City manhole near the Otter Lake Road /Cedar Street intersection. When the Metropolitan Council installs their new gravity trunk sewer across the freeway, the City can connect at Cedar Street/21a Avenue instead of connecting on the east side of the freeway, eliminating the need for the i -35E crossing. As the Centerville Interceptor project proposed by the Metropolitan Council will also require a crossing of I -35E, and as the City will not need the crossing after the Metropolitan Council project is constructed, we propose to install a steel casing pipe across 1 -35E which can be used by the City and by the Metropolitan Council for their project. The proposed JPA calls for the Metropolitan Council to pay for 90% of the cost of the casing pipe and and additional 14% for engineering. The proposed JPA between the City of Lino Lakes and the Metropolitan Council is necessary to define responsibilities and conditions between the two agencies.
