Analysis of the future background conditions was carried out to determine the baseline operating conditions <br />for the Opening Year (2030) and Design Year (2045) of the proposed development. A review of future traffic <br />growth and planned geometric changes for the study roadways was conducted for the analysis. <br />3.1. PLANNED ROADWAY MODIFICATIONS <br />Sunset Avenue is undergoing a reconstruction project which is expected to include the conversion of Sunset <br />Avenue & Lilac Street and Sunset Avenue & 121s' Avenue intersections to roundabouts. A median will be <br />installed along Sunset Avenue and other intersections along the roadway will be converted to right-in/right- <br />out (including Century Trail, Robinson Drive, and any proposed future access points along Sunset Avenue). <br />As this project is ongoing, it is expected to be completed by the studied Opening Year (2030). <br />Anoka County is also planning the installation of a single -lane roundabout at Main Street & Lake Drive. The <br />estimated completion date of this roundabout is 2028. <br />As the AUAR area develops, multiple new roadways will be constructed to provide local access to new <br />developments. Sunset Avenue will be extended north of Main Street to provide access to developments <br />north of Main Street though it has not been determined if it will extend directly to Pine Street. For the access <br />assumptions assumed with the site buildout, see §4.1 (Scenario 1) and §5.1 (Scenario 2). <br />For the purposes of this analysis, it was assumed that there was not an east -west connection in the Opening <br />year scenario on the south half of the AUAR site, in order to be conservative with the analysis and determine <br />if the connection is necessary from a traffic operations standpoint, and if access only from Main Street and <br />Sunset Avenue would be sufficient. However, when the development on the AUAR site south of Main Street <br />happens, it is anticipated that Robinson Drive would be extended to connect to 4th Avenue to provide an <br />additional connection. <br />3.2. FUTURE BACKGROUND GROWTH <br />An annual background growth rate was calculated by comparing the projected 2040 AADTs included in the <br />City of Lino Lakes 2040 Comprehensive Plan to the existing AADTs which were used to develop the <br />projections (2016). A comparison of the major roadways existing and projected AADTs are shown below in <br />Table 3-1. <br />Table 3-1: Roadway AADT Projections and Growth Rates <br />Existing Traffic <br />Projected <br />Traffic <br />Roadway Segment <br />2016 AADT <br />141 AADT <br />Growth <br />North of Main Street <br />8,700 <br />10,000 <br />0.6% <br />Lake Drive <br />South of Main Street <br />11,000 <br />13,200 <br />0.8% <br />4th Avenue <br />South of Main Street <br />1,300 <br />2,500 <br />2.8% <br />Main Street <br />East of Lexington Avenue <br />8,400 <br />13,700 <br />2.1% <br />Sunset Avenue <br />South of Main Street <br />2,400 <br />2,900 <br />0.8% <br />Lilac Street <br />West of 4th Avenue <br />1,850 <br />1,900 <br />0.1% <br />Based on a review of historical AADT trends in the area, Lake Drive and Sunset Avenue are expected to <br />exhibit growth rates of about 0.6% to 0.8% while Main Street and 4th Avenue are expected to exhibit higher <br />Northwest Main - Lino Lakes, MN <br />Traffic Impact Analysis I June 2025 <br />Page 161 of 617 <br />
