StanteC Page 4 of 5 DuRree Road to Southern City Limits The county's current plan shows this area proposed as: • Two -lane rural section roadway • Right turn lanes • 4' paved shoulders where there are no turn lanes • Reclaim- shape- and-pave type improvement • No trails or sidewalks This area is yet to be developed and lends itself to a rural section roadway. We encourage the city to support the current design in this section. There should be no cost to the city for this segment, Trunk Storm Sewer /Stormwater Treatment As you are aware, the City's ultimate plan for the Downtown Redevelopment and for its Downtown Stormwater Reclamation Project necessitates the construction of a 42 -inch pipe coming from the intersection of Centerville Road (CSAH 21) and Sorel Street, south to a discharge point leading into the ditch along the south side of LaMotte Park. The County will need to construct a storm sewer system in areas of urban section roadway and may need to provide stormwater treatment Best Management Practices (BMPs) for the project. Those BMPs could include infiltration features, storm ponds and the like. If the City wishes to construct the 42 -inch pipe now and enter into a joint powers agreement to share that pipe with the County, it could likely handle both the County's storm water and the City's future runoff from the Downtown Redevelopment. If not, a slightly larger pipe probably could. In either case, it would likely be mutually beneficial to share the pipe and therefore realize savings by sharing the cost. Each party might pay a percentage of the pipe's cost based on its contribution to the flow or the County could contribute the equivalent cost of the system they would have needed on their own. The pipe could be constructed under the county's contract, with the City's portion of the cost becoming part of its share of the project costs. Finally, a similar agreement could be reached to have the County share the City's Stormwater Reclamation Facility to the extent in needs to provide treatment or infiltration. Sidewalks and Trails During the course of several design meetings, the logistics of certain trail segments has been discussed. There are many factors which affect the viability of a trail. A few things to note are: The County views trails as a City cost If additional right -of -way is necessary because of a trail, they would view that as a City cost • If additional wetland mitigation was necessary because of a trail, they would view that as a City cost. There are areas of significant wetland impact between Hunter's Trail and Dupre Rd.
