Northwest Main – Lino Lakes, MN Traffic Impact Analysis │ June 2025 8 3. ANALYSIS OF FUTURE BACKGROUND CONDITIONS Analysis of the future background conditions was carried out to determine the baseline operating conditions for the Opening Year (2030) and Design Year (2045) of the proposed development. A review of future traffic growth and planned geometric changes for the study roadways was conducted for the analysis. 3.1. PLANNED ROADWAY MODIFICATIONS Sunset Avenue is undergoing a reconstruction project which is expected to include the conversion of Sunset Avenue & Lilac Street and Sunset Avenue & 121st Avenue intersections to roundabouts. A median will be installed along Sunset Avenue and other intersections along the roadway will be converted to right-in/right- out (including Century Trail, Robinson Drive, and any proposed future access points along Sunset Avenue). As this project is ongoing, it is expected to be completed by the studied Opening Year (2030). Anoka County is also planning the installation of a single-lane roundabout at Main Street & Lake Drive. The estimated completion date of this roundabout is 2028. As the AUAR area develops, multiple new roadways will be constructed to provide local access to new developments. Sunset Avenue will be extended north of Main Street to provide access to developments north of Main Street though it has not been determined if it will extend directly to Pine Street. For the access assumptions assumed with the site buildout, see §4.1 (Scenario 1) and §5.1 (Scenario 2). For the purposes of this analysis, it was assumed that there was not an east-west connection in the Opening year scenario on the south half of the AUAR site, in order to be conservative with the analysis and determine if the connection is necessary from a traffic operations standpoint, and if access only from Main Street and Sunset Avenue would be sufficient. However, when the development on the AUAR site south of Main Street happens, it is anticipated that Robinson Drive would be extended to connect to 4th Avenue to provide an additional connection. 3.2. FUTURE BACKGROUND GROWTH An annual background growth rate was calculated by comparing the projected 2040 AADTs included in the City of Lino Lakes 2040 Comprehensive Plan to the existing AADTs which were used to develop the projections (2016). A comparison of the major roadways existing and projected AADTs are shown below in Table 3-1. Table 3-1: Roadway AADT Projections and Growth Rates Roadway Segment Existing Traffic Projected Traffic 2016 AADT 2040 AADT Growth Rate Lake Drive North of Main Street 8,700 10,000 0.6% South of Main Street 11,000 13,200 0.8% 4th Avenue South of Main Street 1,300 2,500 2.8% Main Street East of Lexington Avenue 8,400 13,700 2.1% Sunset Avenue South of Main Street 2,400 2,900 0.8% Lilac Street West of 4th Avenue 1,850 1,900 0.1% Based on a review of historical AADT trends in the area, Lake Drive and Sunset Avenue are expected to exhibit growth rates of about 0.6% to 0.8% while Main Street and 4th Avenue are expected to exhibit higher Page 189 of 679
