Feasibility Report Page 4 Snelling Avenue North and County Road E - Street and Utility Improvements City Project Number PW 20-0100 DRAFT 2. EXISTING CONDITIONS 2.1 Land Use Properties located within Area 1 (Snelling Avenue North from County Road E to Highway 51) are within the R-1 Single Family Residential District based on the City’s Zoning Map. Two types of properties border the proposed improvements consisting of single family residential properties and two tax-exempt properties located at 3588 Ridgewood Road (City) and 1357 Cummings Lane (State Trust). Properties within Area 2 (Snelling Avenue N and County Road E Intersection) are located in the R-1 Single Family Residential District, with one parcel in the northeast quadrant of the intersection that is zoned within the NB-Neighborhood Business District, generally referred to as the Lindey’s Steakhouse property. The second parcel at 1525 Lake Johanna Boulevard is a R-1 single family residential home with frontage and driveway access within the proposed construction limits of the potential intersection improvements as described below. 2.2 Streets Street improvements considered within the study are organized into two potential improvement areas as described below. AREA 1 – Snelling Avenue North Snelling Avenue North from County Road E to Trunk Highway 51 is an undivided roadway that is approximately 4,300 feet long (0.81 mile) and lies within a 200 foot right-of-way. The northerly 430 feet immediately south of County Road E is an urban section roadway with curb and gutter, two through lanes, one northbound left turn lane and shoulders having an approximate total street width of 44-feet. The remaining corridor is a rural road section having 12 foot driving lanes in each direction and 8 foot paved shoulders, for a total width of 40 feet. Snelling Avenue North was previously a state highway, which was turned back t o the City in the mid-1990s. Soil borings conducted in 2019 indicate fill material varying in depth from 1.5 feet to 11.5 feet and generally classified as clayey sand. Underlying the fill is glacial till consisting of clayey sand and sandy lean clay. The top bituminous pavement thickness ranges from 3-inches to 11-inches thick, with 6-inches to 24-inches of aggregate base above a second lower layer of bituminous pavement along the southern portion of the corridor. A copy of the geotechnical report and soil boring logs are provided in Appendix C. Pavement conditions are highly deteriorated with a current Pavement Condition Rating of 15 out of 100. A majority of the pavement is aging and exhibiting characteristics of distress, such as potholes, rutting, and severe cracking throughout much of the corridor. The demand for frequent pavement patching has become excessive and it is no longer cost effective to maintain the existing pavement though preservation or resurfacing improvements.
