Infrastructure Engineering Planning Construction 701 Xenia Avenue South  Suite 300 Minneapolis, MN 55416 Tel: 763-541-4800 Fax: 763-541-1700 Memorandum To: Elk River City Council Worksession From: Breanne Rothstein, Community Planner WSB & Associates, Inc. Date: March 16, 2015 Re: Draft Gravel Mining Study Area Presentation Background The City Council authorized the preparation of a land use, transportation, utility, and schematic grading study for the 2,600 acre Gravel Mining Area located in northern Elk River along Highway 169. The Study is aimed to answer a number of questions including what are the desired land uses for the area post mining, how can the City work with the miners to establish compatible reclamation plans, how much development can be supported through an extension of the existing sanitary sewer collection system, how will transportation access (both vehicular and pedestrian) and visibility be managed, and how will the neighboring land uses be protected? In December, the Parks Commission, Planning Commission, and City Council reviewed the draft land use scenarios, and selected a preferred alternative, which represented a hybrid of two of the presented scenarios. The WSB team, working in close coordination with Elk River staff, developed the draft study that summarizes the transportation, sanitary sewer, water, grading, and stormwater infrastructure needs associated with the preferred land use scenario. The full draft study is enclosed for your review and reference. The consultant team will present the alternative land use scenario and key findings at the worksession. It is intended that this report will serve as a valuable planning tool when analyzing the level of new growth the city can reasonably accommodate in the short term and mid-term planning period (by 2040). Key Findings In order to accommodate development in Phase 1, which represents the southern portion of the Development Reserve area (530 acres), and is shown on the map below, the following infrastructure improvements are needed:  Convert CSAH 33 to a four-lane, divided roadway from Ranch Road connection through the intersection with CR 121. This upgrade should allow for the eventual conversion to a six-lane roadway. It may be that the roadway is built to a six-lane facility but striped as a four-lane until such time as funding is available to widen the interchange bridge and its ramp terminals.  Construct Proctor Road as a three-lane roadway (at a minimum) north of CSAH 33 to the connection with 221st Avenue. It may be that the roadway is widened enough to accommodate the eventual four-lane divided facility but is striped as a three-lane roadway.  Construct Proctor Road as a four-lane, divided roadway south of CSAH 33 through the southern development area of Zone 1.  Construct 221st Avenue as a four-lane divided roadway from Proctor to the US 169 intersection.
