I..., <br />PROPOSEDIMPROVEMENTS <br />The City has Road Construction Standards. As part of this Study, we have reviewed those <br />standards and, after consultation with City staff, are recommending modifications to them. In <br />many cases we have lessened the standards due to the roadway being a dead -end and serving <br />a relatively small number of lots. <br />The City Standards indicate that generally, the entire R/W should be cleared, except to save <br />desirable timber and other vegetation. Sufficient clearing and grubbing provides space for snow <br />storage — getting water away from and below the roadway helps to maximize the life of the <br />roadbed and surfacing / pavement; maximizing the City investment and minimizing City <br />maintenance. For Wildlife Trail, we are not recommending clearing the entire RNN, and instead <br />are recommending only those tree removals and brush clearing necessary for the roadbed and <br />pavement construction. <br />The City Standards indicate that the roadway should be constructed in the center of the platted <br />R/W. The platted R/W is 66 -feet, which meets City standards. As mentioned before, from field <br />and aerial photo observation, it does appear the existing roadway is close to the center of the <br />platted RNV. Thus, we are estimating proposed improvements without any significant grading or <br />relocating of the roadbed. If the City should choose to make improvements and to make this a <br />City street, we would recommend that a design survey verify the location of the existing roadbed <br />within the R/W. <br />The City Standards say the roadbed width is to be 24 feet shoulder to shoulder and should be <br />crowned. For Wildlife Trail, we are recommending a 2% crowned 20 -foot wide roadbed for the <br />segment from North Sluetter Road to the loop. For the loop, we are recommending an 18 -foot <br />wide roadbed sloped at 1 % towards the middle low area. It should be noted that these will be a <br />little tight to construct in places, and details would need to be further investigated should this <br />project proceed to a design phase. <br />The City Standards provide guidelines on the type of soils and the way the roadbed is to be <br />constructed. As the City was not involved in the roadbed construction, soil borings or some <br />other form of investigative work (e.g. test pits, which would be destructive to the roadbed) would <br />Pequot Lakes —Wildlife Trail Improvements Study <br />WSN No. 0130130044.000 Page 6 <br />
