Storm Sewer in Prior Lake
We have reviewed the storm sewer features of this plan and find
that State Aid funds can bear 59.6% of the cost of the total storm
sewer quantities shown in this plan. Of this amount 18.0% is
chargeable to 201-106-01 and 82.0% to 201-107-01.
The proposed improvements conform with State Aid standards and
further review of the plan will be made by the State Aid office.
Unless you wish to recommend modifying the amount of participation,
the State Aid office will use the above percentages.
Should it be desirable to release State Aid funds on an individual
project basis, State Aid funds Can be authorized for 65.3% of those
quantities shown under MSA 201-106-01, and 58.5% for those shown
under MSA 201-107-01.
We are forwarding a copy of this report to L. J. Anderson, City
Engineer, for his information.

~fter our discussi.on ot .July 26, 1983, concernin/J the rac1ius of
curvature and the superelevation, I thouyht it best to intorn you in
writing our intention in this matter. For our situation, we propose
to una ~ 273 foot radius with a superelevation rate of 0.02 ft./ft.
In a previous discussion. we establ ishe(j the raclius ot curvature to be
27:i f ('H~t. 1,Iii th this rad ius and ;'\ speed of 30 mph, the ?'1n/nOT'Road
Des i90 rlanual, Fi~l. 3-:2;.0 :'H:>, imHcates no :::'o..Iperelevat ion is ne-c-e-ssary.
Tf6tieve-r~-- t.hti-r.injnCI1' sttlte ldd ~~anual, r'i:J. B5-H'12.210, shows a
supereh:vat ion is necessaryfor--tti"e-- same conti i tions. It appears the
(Ufferance lies in the side friction factor. The newer Road Design
Manual allows for a higher friction factor (0.22 versus ij.16 in the
.State --Aid Hanual) in response to reco9ni zen or i Vf::r react. ions aml
e-:i;iectat"fo""r1:';- in -urban areas. our proposea design is a comproll1ise of
the two design concepts.
Please contact us if you have any questions.
