7550 Sunwood Drive NW Ramsey, MN 55303 City Hall: (763) 427-1410 Fax: (763) 427-5543 www.cLramsey.mn.us Memo To: Brian Olson From: Leonard Linton CC: Storm Water Utility File Date: October 22, 2009 Re: Account History for 14000 Sunfish Lake Blvd, 6451 McKinley Street and 6250 Bunker Lake Blvd Staff received a request in May 2009 from Mr. Sharp to recalculate the rates for 14000 Sunfish Lake Blvd, 6451 McKinley Street and 6250 Bunker Lake Blvd. He owns each of the properties and they have similar buildings; however the stormwater utility rates were significantly different for the properties. The storm drainage utility credit application foni1 indicates an owner may request in writing that the fee be recomputed. If an error of more than 20% has been made the fee will be adjusted effective the quarter after receipt of the letter. No adjustments will be made retroactively. The property at 14000 Sunfish Lake Blvd. was included in the original storm water utility calculations performed in 2000 under the name Vadnais Insulation. The property was purchased and developed by Sharp and Associates, Inc. in 2001. The new improvements were submitted to the City for review and approval in 2 phases. The first phaSe review letter was written on February 21,2001 and listed an REU of 21.73 for the 9.7 acre parcel. TIle second phase review letter was written on December 14, 2001 and listed an REV of 26.68 for the same 9.7 acre parcel. The property received fmal plat approval as Sunfish Gateway in June 2002. This plat created the current lots, 140th Court and the lots north of 140th Court from the original 9.7 acres. Staff compared the stOlID water utility accounts on record with the Connexus billing in early 2004. The review indicated 6451 McKinley Street was not being billed for stormwater.. The property was calculated at 4.299 acres and 78% impervious cover for an REU of 16.3. Tllis new billing started April 16, 2004. The REV for 14000 Sunfish Lake Boulevard was not changed from the 18.0 charged to Vadnais Insulation at that time. The PIN book published annually by Anoka county and the 2003 aerial photos were used in the 2004 review, GIS was not used. These calculations were made using the best information available at that time. The review was performed using the most current county parcel data available in GIS and the 2008 color aerial imagery of the City. The results of the review are summarized below:
