• rte-,; .viii Howard R. Green Company October 16, 2002 File: 812620J-0240 Mr. Scott Harlicker Senior Planner City of Elk River 13065 Orono Parkway Elk River, MN 55330 RE: ELK RIVER STATION DEVELOPMENT Dear Mr. Harlicker: As requested, we have the reviewed the most recent submittals for the Elk River Station development, combined with the submittal received on September 12, 2002. The two most recent sheets submitted were a Preliminary Site Plan/PUD dated August 26, 2002, and a Concept for the Commercial Property, which had no date. These submittals were all prepared by Westwood Professional Services for Centex Homes. As you are aware, Centex Homes is planning to develop approximately 298 townhomes on about 50 acres of the site. This would encompass all of the residential development; the remaining commercial development would be done at a future date by a different developer. 1. Public roadways will service most of the development. The majority of the public roadways are shown to be 28 feet in width, face of curb to face of curb, within a 50-foot right-of-way. At the staff review meeting, Cliff Anderson from the fire department expressed concern regarding the 28-foot wide roadways. It is the fire department's opinion that with parking on one side of the 28-foot wide roadway, there is insufficient room remaining to preserve the 20-foot width for emergency vehicle access. However, according to MnDOT design criteria for low-volume roads, which these roads would be considered, a parking lane width is eight feet wide. Thus, the remaining width would allow for a 20-foot wide emergency vehicle access. 2. We have received drainage calculations dated September 14, 2002, from Westwood Professional Services. We have done a preliminary review of these drainage calculations and find them generally to be acceptable. We have a number of minor comments regarding the drainage calculations, which we will share directly with Jason McCarty of Westwood Professional Services. 3. A general review of the grading plan indicated that while the overall plan appeared to be adequate, there are a few items that will have to be reviewed in greater detail at a larger scale. These items have been explained to the developer; they include the grading along and adjacent to the large wetland at the north side of the property, and also a determination of emergency overflows for all portions of the property. 4. There is sufficient capacity for sanitary sewer and watermain to service this development. Generally, the sanitary sewer and water system will be considered public and will be . maintained by the City and the Elk River Municipal Utilities. Final determination of hydrant locations, valve locations, watermain looping, and sewer alignment has yet to be finally determined.
