RE: Rigden Farms Second Filing
Grading Certification for Lot 11
Dear Mr. Barber,
This letter is in regards to 2545 Des Moines Drive, which is Lot 11 at Rigden Farms
Second Filing, and in particular,to provide the City with a Grading certification for this
particular building. The basis for our evaluation is the survey information provided by
RJL Surveys, dated July 27, 2004, and a site investigation July 28, 2004 by Northern
Engineering Services, Inc.
I have attached a copy of the elevations provided by RJL Surveys, as well as the
approved grading plan. The approved construction plans called for a finished floor
elevation of 4925.50 and top of foundation elevation of 4924.50; the actual finished floor
elevation and top of foundation elevation are 4926.91 and 4925.91,respectively,
approximately 1.4' higher than the approved plan. There are two spot elevations on the
north side of the building that are 0.3' to 0.4' below proposed grade, all other spots
elevations are less than 0.1' difference from the approved grading plan. There does
appear to be sufficient grade away from the buildings to encourage positive drainage, the
lot grading does essentially comply with the approved grading plan.
Please let me know if you have any questions regarding this certification.
