RE: Brackey Retail—Review of Revised Plans
To whom it may concern,
Kimley-Horn received the Review of Revised Comments letter via email on September 27, 2016 for the proposed
development located at the intersection of 60th Street North and Krueger Lane in Oak Park Heights, MN. All of the
Review Findings from the Report have been copied below and Kimley-Horn offers the corresponding responses in
red. Please review and let me know if there are any questions in regard to the responses offered.
Stormwater/Drainage
1. The project is subject to review by the Brown's Creek Watershed District.The City shall
be provided a copy of the permit approval letter from the BCWD prior to the
commencement of construction activity.
The owner shall send the City a copy of the permit approval letter from BCWD.
2. The proposed filtration pond shall be installed with an impermeable liner directly below
the draintile to minimize infiltration within the City's High Vulnerability Drinking
Water Supply Management Area.
Sheet C4.1 Grading and Drainage Details has been updated with changes to the filter fabric of the filtration
pond.
Traffic Analysis Letter
1. It is assumed that Washington County or MnDOT has requested this letter(not Ramsey
County).
The requesting agency has been changed to MNDOT.
2. Please include the date of the traffic counts in the third paragraph under Existing
Conditions(Page 1).

Data of traffic counts has been provided in the memo.
3. Provide justification that land use code 826 is appropriate for lots 1 and,in particular,
lot 3.
A more detailed description of why Land Use 826 was chosen is provided in the memo.
4. Provide existing traffic volumes for 6oth Street North and Krueger Lane,including PM
Peak volumes.
Daily and peak hour volumes were not readily available along 60th and Krueger.Since intersection capacity
analysis was not required,counts were not performed.
5. Using the fitted curve equation instead of the average rate would result in 85 total
vehicles at the PM Peak Hour for the Specialty Retail Center(Table 1):
The trip generation calculation has been updated to use the fitted curve equation for ITE 826.
6. The internal capture percentage in Table 1 is ok if code 826 is appropriate for the
specialty retail.
The internal capture remains the same since we are still suggesting to use ITE Land Use 826.
7. The assumed trip distribution shown on page 2 does not match Exhibit 2.
The trip distribution has been updated so that the memo and exhibit are consistent.
