Re- 3220/3240 Watertown Road ,
Plat No. 04-2971
File No. 139-04-000 L
Dear Mike, 3 30
W A-V c�a w vitD aA
We have reviewed the preliminary plans for the proposed two lot subdivision on the site located at 3220/3240
Watertown Road.The proposed use is for single-family homes.The two lots will be served by a single shared
driveway constructed across Outlot A. The driveway to serve Lot 1 requires the construction of a creek
crossing and culvert installation. The creek crossing results in some wetland impacts and mitigation will be
necessary. We have the following comments in regards to engineering matters.
• The proposed culvert size appears to be acceptable however we recommend the culvert be an arch RCP so
as to reduce the overall height of the structure.
• The low point on the driveway at the creek crossing should be lowered from 73.0 t 972. o provide
adequate freeboard for the home on Lot 1.
• Plans should be submitted to the Minnehaha Creek Watershed District for review and approval.
• Final plans should include plan and profile views of the driveway from Watertown Road to the proposed
home site on Lot 1. The finished driveway should be paved and the plans should include atypical
driveway section. Driveway grades should not exceed 10% at any location.
• Plans should include storm water treatment provisions. This might include best management practices
(BMP's)such as filter strips,buffers, infiltration areas, etc.
• Driveway easements should be in place for Lots 1 and 2 across Outlot A.
• Erosion control measures should be installed,inspected and approved by the city prior to any work on site.
• The fire chief should review and comment on the access,particularly to Lot 2.
Please contact me at(651)604-4863 if you have any questions regarding this
Yours very truly, Ian
