As you are aware, we have had numerous ongoing conversations regarding this subject over the past several weeks. e,....~:,'.G~;:.::R:~;G Currently, Pascal A venue is approximately 21 feet wide with minimal, if any, bituminous I E"ti:~CI\"'<C\::':". berm on the outer edges. It is a dead-end road with the nonh end having two houses fairly /v',;J'{UA~ close to the street. Our recommendation has been to construct a 24-foot wide street, P:.,''''''NI~;::; including the concrete curb and gutter. The width of the concrete gutter is approximately eI scuc "''V)\S~t 18 inches, so to arrive at 24 feet, we would maintain the same bituminous width and S!,:;J'::-~;:'L essentially place the concrete curb and gutter on the outer edges, The residents have S~.SJ'J\,G requested consideration of a narrower width, possibly 22 feet wide, I r~A.~~;C PA';S?opr.'-'i:C.'i The Minnesota Department of Transportation does recognize II-foot lanes, but they also ha ve a standing recommendation that there be a 2-foot reaction area on any lane which I E:.:'::;:;:'CAL'V::.......,\i'C,!.. abuts an outside edge or an inside median, Given these design criteria, the minimum hC;:~'.c:;:oi0 ~"".< recognized Municipal State Aid width roadway is 26 feet--two lI-foot lanes with 2-foot I P:::::'''::~ C.IST~!~JTiC\ reaction area on either side, On higher speed roads, the lane width recommendation from SC'/!;:'A MnDOT is 12 feet. We feel comfortable in recommending a 24-foot width for Pascal S'IS iE,'.', :::O~GJ~S Avenue, being either two 11-foot lanes with I-foot reaction area, or two 12-foot lanes with I no reaction area on the outside edges, A 24-foot street width is also a widely recognized section used in areas of tight constraints, being either physical structures such as houses or natural features such as large diameter trees, or in areas that have a limited traffic I volume such as a cul-de-sac or a dead-end road. We would caution the City that narrowing the street to 22 feet may expose the City to some liability should there ever be a traffic accident. I Finally, we would recommend that the City make their street width determination for . OFFICES IN Pascal A venue based on the unique features found on this street, namely, the houses close MINNEAPOLIS to the street right-of-way, the existing width of the street, and the fact that it is a dead-end ..
