TKDA • ENGINEERS • ARCHITECTS • PLANNERS MEMORANDUM 1500 Piper Jaffrey Plaza 444 Cedar Street Saint Paul, MN 55101 -2140 (651) 292-4400 (651) 292 -0083 Fax www.tkda.com To: James Studenski, City Engineer Reference: Eagle Brook Church Copies To: City of Lino Lakes, Minnesota From: Scott A. Brink, P.E. Date: January 7, 2004 Comm. No. 12701 -002 Routing: This memorandum has been prepared to update the memorandum dated December 26, 2003. Review memorandums dated November 5, 2003, and December 4, 2003, have also been previously prepared for this proposed church construction. Since the previous review of December 26, 2003, drainage calculations have been reviewed, and some additional issues have been identified. This review memorandum is therefore essentially a repeat of the December 26, 2003 memorandum with some additional comments added. Comments provided in other previous memorandums may also remain effective as applicable. Comments are as follows: General 1. Potential drainfield sites were analyzed at 7709 20th Avenue North and soil borings performed. A requirement of replatting the property is that the existing home must have an alternative drainfield site within its proposed boundaries. As a result of the findings (loamy fine sand over clay loam and a seasonal high water table ranging from 28 -42" below the surface), an above grade drainfield or mound system will be required. A Preliminary Plat sheet for Eagle Brook Addition has been received. The plat provides for division of the property into two lots: An 82.897 acre parcel containing the Church, and a 6.232 acre parcel to provide for maintaining the existing residential property on the southeast side of the property. A table figure of 2.385 acres for right -of -way dedication for 20th Avenue North (County Road 21) is also provided. An additional 165 feet right of way will also be required from the small parcel of property located along 20th Avenue North near the north end of the property. This is an existing single family unit that is not part of the Church property. However, the proposed roadway widening does extend in front of this property, and the additional dedication is required. The Plat will require the review and approval of Anoka County, and approval will likely be contingent upon dedication of all required right -of -way. The applicant shall therefore be responsible for all right of way dedication and acquisition as required, including property not owned by the Church. In addition, provisions regarding septic and drain field for this property as explained in Item 1 above must be considered. An Employee Owned Company Promoting Affirmative Action and Equal Opportunity
