Summary of Erosion and Sediment Control Compliance on
Sites after Receiving the Winterization Letter.
1. 4701 West Branch Road. No functioning perimeter protection on site, all open soil
should be enclosed with perimeter protection.

was open soil on site but it is considered active so at this time it does not need to be
stabilized.
3. 3186 North Shore Dr. Silt fence on site needs maintenance and there was open soil on
site but it is considered active so at this time it does not need to be stabilized.
4. 3825 Cherry Ave. Perimeter protection is in place and functioning properly and all of
the open soil has been stabilized for winter.
5. 2933 Casco Point Rd. Silt fence on site needs maintenance and there was open soil on
site but it is considered active so at this time it does not need to be stabilized.
6. 1981 Fagerness Point Rd. Perimeter protection is in place and functioning properly,
there was open soil on site but it is considered active so at this time it does not need to be
stabilized.
7. 3485 Crystal Place. Perimeter protection is in place and functioning properly, there
was open soil on site but it is considered active so at this time it does not need to be
stabilized.
8. 70 Wear Lane South. Project is complete and all open soil has been stabilized with
sod.
9. 200 Biederwood Dr. Perimeter protection is in place and functioning properly, there
was open soil on site but it is considered active so at this time it does not need to be
stabilized.
10. 2100 Shadywood Rd. Silt fence on site needs maintenance and there was open soil

Evelyn,
As requested I stopped by all of the sites you mailed the Winterization Letter to and have attached a summary report of
the things I saw at each of the sites. For the most part all of the projects that should have temporary or permanent
stabilization down for the winter did. The only problems I saw were; one project had no perimeter protection and a few
projects had silt fence that needed to be fixed up and maintained. Please feel free to contact me immediately should you
have questions on any of the sites.
Thanks,
Chad Johnson, CPESC, CPSWQ

Chad:
Tom reviewed your letter and indicated it was appropriate to send out to the smaller
projects that you haven't been monitoring. I left your name on it because I didn't think
there was anyone here who could answer technical questions about it. Because of the
delay in sending it out I added a few days to the compliance deadline. These are going out
in today's mail so you can expect phone calls on Monday.
All but two of these are single-family houses under construction on isolated lots. Some
have just commenced, some have been under construction for a while. Crystal Place is a
detached garage on a tiny lot that disturbed most of the lot. (Jasin even removed part of
his house to provide access to the garage.) Cherry Avenue is a major addition between the
lake and a wetland. Tom and Darren reviewed the grading plans for all these permits.
There may be more letters going out next week as I dig more information out of the permit
system.

RE: Permit 2009-00351 -70 Wear Lane South
The active summer construction season is fast drawing to a close here in the state of winter and frozen
ground. As we move into a new season it is important we take the proper precautions on our active sites
to help eliminate any erosion problems or added expenses that may be incurred due to winter freeze thaw
events and the inevitable spring runoff. As construction continues throughout the winter in the City of
Orono it is important to minimize the amount of open soil by providing temporary or permanent cover,
one of the key elements in preventing soil loss. It is also required that the appropriate BMPs be
maintained on-site by December 1, 2009 as follows:
• Exposed soil areas must be stabilized with the appropriate seed mix and erosion control
blanket, disc anchored mulch applied at a rate of 2 tons per acre or other effective means to
control erosion.
o Areas requiring stabilization will include but are not limited to small miscellaneous
areas, landscaping areas, sidewalk backfill,non-active stockpiles, finished grading
areas, etc.
o Areas being worked after November 26th must be stabilized weekly until
construction ends.
o In the event that it snows and there are frozen ground conditions,mulch can be
applied effectively over the snow.
• Seeding must be completed with the appropriate seed mix as indicated below. Dormant
seeding shall be done in the later fall after the soil temperature is consistently below 50
degrees Fahrenheit. Seeding done before or after the indicated seed dates may require
reseeding if the seed does not take. In the event that it snows and there are frozen ground
conditions, seed can be applied effectively over the snow.

• Rock construction entrances to access the construction site and prevent tracking sediment
off site
• Silt fence or an approved perimeter control device shall be installed to control runoff
• Soil stockpiles should be eliminated or consolidated to the extent as possible and be
protected with perimeter control and mulch applied on all stockpiles that will remain dormant
for the winter months.
• Storm Sewer inlet protection including curb and gutter catch basins,parking lot/road drains,
and backyard drop inlets must be:
o Maintained in a manner where all removal of sediment and debris,repairs as
necessary, and or replacement are completed by November 26th, 2009. Sediment shall
be removed when occupying greater than 1/3 the volume of the device,placed in an
upland area and stabilized.
o All"in-structure"and"on-structure devices shall be removed from the storm sewer
inlets by November 26th, 2009 and re-installed in the storm sewer inlets by April 1,
2010.
BMP installation, such as silt fence,has a tendency to be more costly to install during the winter months
therefore it is recommended that all installation occur prior to the ground freezing on sites where work is
proposed to be done during the winter months. Regular construction site inspection will occur throughout
the winter months, and compliance with the Minnesota Pollution Control Agency(MPCA) construction
site general permit and the City Land Disturbance Permit will be expected.
If you have any questions regarding these construction site winterization issues,please feel free to contact
me at 651-325-6860. Thank you for your cooperation in preserving the surrounding natural resources
within the City of Orono.
