RE: Permit Application#00-243
Dear Mr. Evenson:
On July 20, 2000, the Hennepin County Transportation Department initially submitted
application to Minnehaha Creek Watershed District(MCWD) for permitting under rules B, D,
and N. The City of Orono passed Resolution#4485 approving the County's proposal on June
26, 2000. A copy of the signed resolution was transmitted to the District on November 17,
2000. The District reviewed the permit application and requested additional information. The
information was complied and submitted to the District on August 10, 2000. The permit
application was approved by MCWD staff with recommendation for approval with two
conditions: 1) a maintenance agreement for the sump catch basins and expanded wetland must
be executed and recorded, 2) a declaration for preservation of the wetland buffers must be
executed and recorded.
The MCWD Board of Managers met on August 24, 2000, with the Board tabling the
application. The Board requested that MCWD staff work with the County on minimizing the
impacts to wetlands and their associated buffers.
The MCWD and County staff inet on December 13, 2000, for historic aerial photo review to
determine if the wet area in question is a wetland or an excavated stormwater pond. The
County has summarized the findings.

Re: Permit Appliation 00-243
Dear Mr. Evenson:
On December 17, 1999 I submitted a project notification form and supporting wetland
documentation for the proposed salt storage building at the Hennepin County maintenance
facility in Orono. A revised notification form and wetland delineation report were submitted on
July 20, 2000 with plans regazding erosion control measures, rate control of storm water runoff
and re-vegetation of disturbed areas. These plans were revised again based on comments by District
staff and resubmitted on August 10, 2000. District staff determined that the revised plans met
District requirements and approval of the revised plans was placed on the consent agenda for the
District's August 24 meeting. Mr. Guy Nowlan, Hennepin County Transportation Department,
attended the August 24 meeting to answer any questions the Board might have concerning the
project. The District Board expressed concern regarding the proposed wetland impacts and ta.bled
the application. In addition, the Board directed District staff to meet with County staff regarding
the application. Prior to meeting with District staff, County staff reviewed the submitted plans as
well as eazlier preliminary drafts. The development of the site plan is summarized in the
following paragraphs.
The original site inspection and delineation was conducted on September 2, 1999. The
inspection confirmed that the site had no wetlands protected by the Minnesota Department of
Natural Resources (DNR) and three wetland areas were delineated. The proposed project did not
result in any wetland areas being filled. One wetland area would be impacted by excavation
activities. At that time, the Minnesota Wetland Conservation Act (WCA) did not require
, replacement of excavation impacts provided the excavation did not result in a change of type.
The proposed excavation would not result in a change of type. The proposed excavation impacts
(less than 0.1-acre) were below the U.S. Army Corps of Engineers threshold for wetland
mitigation. The impacted area was not on the City of Orono's protected wetland list or map.
Although not required, the preliminary plans did create 4,064 square feet of type 1/2 (PEMA/B)
� new wetland credit (NWC) and 9,767 square feet of buffer. Approximately one third of this

�
buffer(4,064 ft2 x 75% =3,048 ft2) would be eligible as public value credit (PVC). Replacement
credits, if required, would total 7,112 square feet (4,064 ft2 NWC + 3,048 ft2 PVC = 7,112 ft2)
and exceed a 2:1 replacement ratio. Due to the nature of the project, the limited impact and the
creation of wetland credits not required by the WCA, County staff did not expect problems with
the approval of the project by the District. Since problems were not anticipated with approval of
the project, County staff did not review historical aerial photos of the site to try to resolve
questions regarding whether or not the impacted wetland qualified for exemption from WCA
requirements.
The project was delayed due to changes in the building design required by the City of Orono.
During this period the WCA requirements regarding excavation impacts were changed. WCA
rules now require that impacts resulting from excavation in type 3, 4 and 5 wetlands be replaced.
County staff did not view this rule change as a serious problem because the voluntary wetland
mitigation originally proposed was sufficient to meet WCA requirements. The final submittal
was made on August 10,2000.
After the County's application was tabled, whether or not the impacted area qualified for
exemption from WCA requirements was now germane. County staff reviewed aerial
photographs from 1953, 1957, 1964, 1969, 1975, 1979 and 1989. The aerial photographs indicate
that the area was filled between 1957 and 1964. Additional review showed that the County
excavated a storm water pond on this site. Over time this pond has developed wetland
characteristics but is exempt from WCA requirements (Minnesota Rules 8420.0122 Subp. 5).
County staff inet with District staff on December 13, to review the aerial photographs. Although
the District staff agreed with the interpretation of the photographs presented by County staff,they
requested that a technical evaluation panel (TEP) review the photographic evidence and confirm
that the area is exempt from WCA requirements. The TEP, based on the photographic evidence,
found that the impacted area was excavated to create a storm water pond sometime between 1979
and 1989. The TEP confiimed that the azea is not a jurisdictional wetland and the proposed
excavation does not require any wetland mitigation. I believe the findings of the TEP and District
staff should address the Board's concern regarding this project.
Sincerely,

STORMWATER FACILITY MAINTENANCE
These terms apply to the stormwater facilities constructed pursuant to Minnehaha
Creek Watershed District permit application number
WHEREAS,Hennepin County has applied for a permit from the MCWD pursuant to
MCWD Rule B, Stormwater Management; and
WHEREAS,the property that is the subject of this agreement is legally described in
the Declaration into which tlus Attachment is incorporated and the facilities on the property
to which these maintenance requirements apply aze as follows:
WHEREAS,MCWD Rule B provides, "A maintenance agreement shall be submitted
for: stormwater treatment ponds, outlet structures for such ponds, culverts, outfall structures
and a11 other stormwater facilities. This maintenance agreement shall specify methods,
schedule and responsible parties for maintenance and must include at a minimum,the
elements contained in the District's Maintenance Agreement Form.
NOW,THEREFORE:
1. Hennepin County shall inspect the stormwater retention and treatment basin(s)
at a minimuxn of once a year to determine if the basin's retention and treatment
characteristics are adequate. A storage treatment basin will be considered inadequate if
sediment has decreased the wet storage volume by %Z of its original design volume. Based
on this inspection, if the stormwater basin(s) is identified for sediment cleanout, Hennepin
County sha11 restore the basin(s)to its original design contours within one year of the
inspection date.
2. Hennepin County shall inspect the grit chambers, sump catch basins, sump
manholes,outlet structures, culverts,outfall structures or other stormwater facilities for the
project in the spring and fall of each year. Hennepin County shall remove a11 sediment and
debris during the inspections such that the stormwater facilities operate as designed and
permitted.
3. This Declazation and agreement shall be in full force and effect upon the date
of execution for a seven year period. '
4. Violation of the inspection and/or maintenance provisions of this Agreement
is a violation of the MCWD permit for the project for which the MCWD may take action
against Hennepin County.
' Hennepin County agrees that it will be responsible for its own acts and the results
thereof,to the extend authorized by the law, and shall not be responsible for the acts of the
other party and the results thereof. The County's liability is governed by the provisions of
