<br /> Dear Mike:
<br /> We have reviewed the construction plans dated 5/8/03 for the Professional Properties building.The
<br /> site is located at 2765 Kelley Parkway in the northeast quadrant of the intersection of Old Crystal
<br /> Bay Road and T.H. 12. We have the following comments in regards to engineering matters.
<br /> • Storm sewer calculations should be revised and resubmitted to include CBMH-6 and CBMH-
<br /> 7. The drainage area map should be revised to reflect the proposed grading.
<br /> • The proposed storm sewer is shown connecting to a future storm sewer.Plans should include
<br /> provisions for a pond if the future storm sewer isn't available in time to serve this site.Plans
<br /> should include a pond designed to meet NURP standards.Ponding calculations along with
<br /> pre and post development drainage area maps should be provided.The pond should include
<br /> an outlet structure designed to provide one-foot of skimming and limit post development
<br /> flows to pre development rates.
<br /> • The plans should include provisions for traffic control for the proposed work on Old Crystal
<br /> Ray Road and Kelley Parkway.
<br /> • The plans should include a bituminous trail typical section showing 6-inches of class 5
<br /> aggregate base and 3-inches of type 41A bituminous wear course.
<br /> Please contact me at(651) 604-4863 if you have any questions regarding this matter.
<br /> Yours very truly,
<br /> BONESTROO,ROSENE, ANDERLIK&ASSOCIATES, INC.
