Regular and TAC Meeting Minutes

April 13, 2016

I. A meeting of the Technical Advisory Committee (TAC) for the Elm Creek Watershed Management Commission was called to order at 9:36 a.m., Wednesday, April 13, 2016, in the Mayor’s Conference Room, Maple Grove City Hall, 12800 Arbor Lakes Parkway, Maple Grove, MN by Doug Baines.

Present were: Todd Touminen, Champlin; Doug Baines, Dayton; Liz Weir and Kaci Fisher, Medina; Mark Lahtinen and Rick Lestina, Maple Grove; Ben Scharenbroich, Plymouth; Andrew Simmons, Rogers; Jeff Weiss, Barr Engineering; Ali Durgunoğlu and James Kujawa, Hennepin County Dept. of Environment and Energy (HCEE); Rich Brasch, Three Rivers Park District (TRPD); and Judie Anderson and Amy Juntunen, JASS.

Also present: Steve Christopher, Board of Water and Soil Resources (BWSR);

A. Motion by Kujawa, second by Scharenbroich to approve the TAC agenda.* Motion carried.

B. Consider proposed 2016 Capital Projects.

1. Fish Lake Alum Treatment, Phase I, Maple Grove.* Sediment cores were collected from Fish Lake and the alum dosage has been determined. The sediment cores prove that 70% of the lake’s phosphorus load comes from internal loading. The project will be contingent on grant funding from BWSR. The alum treatment will treat sediment at 30 feet and deeper. Motion by Kujawa, second by Scharenbroich to recommend Commission approval of the project at a cost of $75,000 in 2017. Motion carried unanimously. BWSR grants will be open July‐August and awarded in December 2016.

2. Rush Creek Main Stem Restoration, Maple Grove.* This project involves the stabilization of the erosion‐prone sites in a 2900 linear foot portion of Rush Creek within The Enclave on Rush Creek project. The initial erosion was likely due to increased flows from the developing watershed. Erosion has caused encroachment into the adjacent woods and trees and other debris to fall into the creek. The debris in the creek has resulted in diversion of flows causing accelerated erosion in most outside bend locations. Motion by Kujawa, second by Scharenbroich to recommend Commission approval the project at a $75,000 cost share. Motion carried unanimously.

3. Elm Creek Dam at the Mill Pond.* This project is a portion of a $7+ million project to replace the Elm Creek dam and bridge, public access construction, and flood mitigation at the Mill Pond in Champlin. The project will construct a new spillway capable of conveying the 100‐year peak discharge. A new exterior weir will also be constructed. A 105 foot interior weir will contain low flows in a rock‐lined channel. The project addresses several safety issues with the existing dam and allow for the drawdown of Mill Pond for maintenance of the impoundment and management of aquatic invasive species. Motion by Lestina, second by Scharenbroich to recommend Commission approval of the project at a cost share of $187,500. Motion carried unanimously.

4. Mississippi Point Park Riverbank Repair, Champlin.* Champlin is requesting up to $75,000 for this project. The project is located in a city‐owned park on the Mississippi River and is eligible for up to $180,000 in state funding. Staff determined that this section of the Mississippi River Bank is in the Elm Creek Watershed. Motion by Kujawa, second by Scharenbroich to recommend conditional Commission approval of the project at a cost not to exceed $75,000 or 25% of the remaining cost after state funding. Motion carried unanimously.

5. Fox Creek Restoration, Rogers.* This is the second phase of the Fox Creek stream bank stabilization. This section includes a residential and industrial section of Rogers. The stream experiences extensive bank failures, undercutting, and brush in the stream due to runoff from a housing development built in the early 1990s. This project is on private property, but residents are unlikely to disturb the restoration area. The City Engineer, WSB, has completed the

Item 2a

*in meeting packet


application. Buffer between the residential lots and the stream, as well as signage, should be included in the plans. Project cost at 25% is $80,312. The project will require a DNR permit. Motion by Touminen, second by Kujawa to recommend conditional Commission approval based on the results of the feasibility study. Motion carried unanimously.

C. Met Council Stormwater Grants. Christopher noted that the deadline for these grants is May 11 and encouraged that all projects in the approved CIP should apply for this grant. Grants must be submitted by the watershed.

D. Adjourn. The TAC meeting was adjourned at 10:48 a.m.

II. A regular meeting of the Elm Creek Watershed Management Commission was called to order at 11:31 a.m., Wednesday, April 13, 2016, in the Mayor’s Conference Room, Maple Grove City Hall, 12800 Arbor Lakes Parkway, Maple Grove, MN by Chairman Doug Baines.

Present were: Gerry Butcher, Champlin; Jon Bottema, Corcoran; Doug Baines, Dayton; Joe Trainor, Maple Grove; Elizabeth Weir, Medina; Fred Moore, Plymouth; Ali Durgunoğlu and James Kujawa, Hennepin County Dept. of Environment and Energy (HCEE); Rich Brasch, Three Rivers Park District (TRPD); Jeff Weiss, Barr Engineering; and Judie Anderson and Amy Juntunen, JASS.

Not represented: Rogers.

Also present: Todd Tuominen, Champlin; Mark Lahtinen, Maple Grove; Ben Scharenbroich, Plymouth; Andrew Simmons, Rogers; and George Schneider, Rice Lake Association.

A. Motion by Weir, second by Moore to approve the agenda.* Motion carried unanimously.

B. Motion by Weir, second by Moore to approve the minutes* of the March 9, 2016 meeting. Motion carried unanimously.

C. Motion by Moore, second by Weir to approve the April Treasurer’s Report and Claims* totaling $15,317.21. Motion carried unanimously.

III. Open Forum. No one was present to speak to matters not on the agenda.

IV. Action Items.

A. Select CAMP Lakes. Cowley and Jubert lakes, along with either Laura or Dubay, will be monitored dependent on volunteer availability.

[Butcher arrived 11:32 a.m.]

B. Project Reviews.*

1. 2015‐039, The Enclave at Dunlavin Woods, Maple Grove.* This is an 18‐acre parcel located in the southeast intersection of CSAH 101 and 101st Avenue. The applicant is proposing to subdivide this parcel into 29 single‐family residential lots. Water reuse from the pond to irrigate areas is planned to meet the abstraction requirement. Two ponds provide treatment for rate and nutrient control. Staff recommends approval of the site plan with the condition that the City confirms the emergency overflow of the eastern wetland to allow one foot freeboard to the homes on the east side of the development. Motion by Weir, second by Butcher to approve Staff findings dated March 18 with the condition stated. Motion carried unanimously.

2. 2016‐001, CSAH 115/County Road 116, Medina.* This project is located on County State Aid Highway (CSAH) 115 and County Road 116. The project will include reconstruction of the roadway, including widening of the road from the existing two‐lane roadway, constructing dedicated turn lanes, drainage improvements, and the construction of a paved pedestrian and bicycle trail. The purpose of the project is to increase capacity of the intersection and improve mobility and safety for all transportation system users. Construction is anticipated in the spring of 2017. Based on soil types and water table elevations, infiltration is not feasible within the project area. Abstraction credits of 0.84 acre feet are proposed for use of an iron‐enhanced filtration system. Staff recommends approval contingent upon 1) modifications to the final design to reduce the two‐year peak runoff to below existing conditions; 2) the wetland mitigation plan being finalized and approved prior to wetland impacts; and 3) receipt of recorded and approved

Item 2a


*in meeting packet


operations and maintenance plans for all stormwater management features, including the enlarged pond, iron‐enhanced biofiltration system, and SAFL baffles. Motion by Weir, second by Moore to approve Staff findings dated April 7 contingent upon the four conditions listed. Motion carried unanimously.

3. 2016‐008, Northwest Greenway Trail Phase II, Plymouth.* The City Of Plymouth is proposing to construct a 1.3 mile long, 12‐foot wide paved trail lane on 3.4 acres running from Vicksburg Lane westward to Plymouth Dog Park near the County Road 47 and Elm Creek. The proposed project will place 254 cubic yards of fill and 258 cubic yards of cut within the designated floodplains. Site plans meet with the Commission’s standards. Staff recommends approval of the project. Motion by Weir, second by Moore to approve Staff findings dated April 7 as presented. Motion carried unanimously.

4. 2016‐014, Balsam Apartments, Dayton.* This is an existing 2.5 acre commercial lot within the Dayton River Commercial Park Addition (Lot 3, Block 1), located near the SE corner of Balsam Lane and Dayton River Road (CSAH 12). This area was reviewed as Northeast Dayton Utility & Street Improvements (ECWMC #2006‐075). The project will consist of a multi‐story apartment complex, an underground parking garage, a parking lot, two rain gardens and all the related utilities. Staff recommends approval contingent on 1) A sequencing plan for the infiltration basin being added to the erosion control plans; 2) Drainage and utility easements provided over the rain gardens; and 3) A recorded operations and maintenance plan agreement with the City of Dayton, unless the City agrees to maintain the rain gardens. Motion by Weir, second by Trainor to approve Staff findings dated April 6 with the three conditions listed. Motion carried unanimously.

5. 2016‐16, Wayzata High School Varsity Baseball Field Improvement, Plymouth.* In their findings dated April 6, 2016, Staff approved this project administratively with two conditions. Staff recommends adding a rain garden for additional treatment, but the City of Plymouth does not encourage rain gardens on public property. The City is working with the school to use an iron‐enhanced bio‐char filtration system instead.

C. 2015 Annual Activity Report.** The report is due to BWSR on April 30. Commissioners should submit any comments to Staff by April 22. Motion by Moore, second by Weir to accept the 2015 Annual Activity Report. Motion carried unanimously.

Dear Mr. Baines:

I request that Hennepin County’s review deadline for the proposed plan amendment be extended to July 28, 2016. The need for the extension is due to the County’s 2016 meeting dates, formal review process and the lead time required to place the item on the County Board’s meeting schedule. I have attached the schedule for Board action on the proposed amendment for your reference.

BAR for amendment approval and maximum levy submitted to Department Administration: May 26 Department Administration reviews and forwards BAR to Public Works Administration: June 23 Public Works Administration reviews and forwards BAR to County Administration: July 5 BAR is communicated to Board on: July 12 BAR in committee on: June 19 Board action on amendment: July 28

Sincerely,

STAFF REPORT May 4, 2016

2012‐021 Kreps Wetland Violation, Corcoran. Kreps constructed a driveway access into his property without obtaining the necessary WCA permits. The DNR issued a Cease and Desist order to Kreps and his contractor in 2012. In November 2012 a Technical Evaluation Panel (TEP) found that three wetland impacts occurred as a result of his work. A restoration order was issued requiring restoration of the site outside of the driveway foot‐print and a 4:1 replacement (through the BWSR wetland banking program) on the areas impacted by the driveway. Final impacts from the driveway footprint and side slopes are expected to be approximately 3,500 SF. Kreps requested an extension of the restoration order to May 20, 2014, pending resolution of issues with the neighbors. The DNR has issued a lien on the property. A court‐ordered mediation and trial of the driveway issues have been ongoing since March 2015. Extensions to the restoration deadline have been granted pending the court’s resolution. An email from Kreps on July 23, 2015 stated the final court order required them to follow the original driveway easement alignment. The original driveway easement is not where the wetland impacts took place, so all wetland fill will be removed and restored to the original conditions in the spring of 2016. Construction started on the restoration March 28. Staff inspected the site on April 1, 2016, and again on April 6 and 22. The site restoration is complete and seeded. A certificate of completion was issued by the SWCD and the DNR can remove the lien on the property. Total time for bill back in April was 2.5 hours. This item will be removed from the report.

2013‐041 Jomico, Corcoran. This is a wetland violation reported by the City. It is a commercial/industrial site located just west of CSAH 116 near downtown Corcoran. A restoration order was issued to remove all wetland fill before September 15, 2014. Subsequent extensions extended the deadline to September 15, 2015. Staff inspected the site with the excavator on September 15 and found minor restoration issues remaining. These were enumerated in the October Staff Report. Retaining wall work, debris and material piles are scheduled to be finished by January 15. Final grading and seeding of rutted areas will be done by May 20, 2016.

2013‐046 Woods of Medina. Medina. This is two parcels totaling 9.5 acres located east of CR 116 and south of Hackamore Road. The site is proposed to be developed into 16 single‐family residential lots. At its January 13, 2015, meeting the Commission approved this project with two conditions: 1) a pond operations and maintenance agreement must be provided, approved by the City and the Commission, and recorded on the title to the property. The recording must be done within 90 days of the final plat approval; and 2) a copy of the approved wetland replacement plan must also be provided. Final platting will be done when the landowner sells the property or decides to develop it himself.

2014‐015 Rogers Drive Extension, Rogers. This project involves improvements along Rogers Drive, extending from Vevea Lane to Brockton Lane. The project is located east of I‐94, south of the Cabela development. The total project area is 8.0 acres; proposed impervious surfaces total 5.6 acres. Site plans received July 1, 2014 meet the requirements of the Commission with the exception of the nutrient control. Due to limited options to treat the nutrient loads on the east 1.7 acre portion of Rogers Drive, the Commission approved the site plan contingent upon the City deferring 4.6 pounds of phosphorus for treatment in future ponding opportunities as the easterly corridor of Rogers Drive develops. 2.3 pounds will be accounted for in the Kinghorn Spec. Building site plan with 2.3 pounds still outstanding. This item will remain on the agenda until the total deferral is accounted for.

2015‐001 Highway 47/Troy Lane School and Development Site, Plymouth. The Commission received a plan application for review of this parcel on January 19, 2105. The submittal was missing some of the required components of the Commission’s newly adopted Rules and Standards and considered incomplete. Revised plans were submitted on April 23 and 30, 2015. At its May 13, 2015 meeting the Commission approved the project with three conditions. The only outstanding item is the recording of the O&M plan and agreement on the school pond. Staff requested an update on the status of these documents on May 4.

Item 5c

Staff Report May 4, 2016 Page 2



2015‐004 Kinghorn Outlot A, Rogers. This is a 31 acre site located between the Clam and Fed Ex sites in Rogers on the west side of Brockton Road and I‐94. The proposed site will have two warehouse buildings, 275,000 and 26,000 SF in size, with associated parking and loading facilities. The Commission standards require review of stormwater management, grading and erosion controls and buffers. A complete plan was received May 14, 2015. At their June 2015 meeting the Commission approved this project with three conditions. These items have not been satisfied as of this update.

2015‐006 Veit Building and Parking Lot Addition, Rogers. This site is located at the Veit Headquarters Building at 14000 Veit Place. It is bound by I‐94 to the north and Industrial Boulevard to the south and east. Fox Creek/DNR wetland #27‐02920 is west of this property. The owner proposes to extend the main building entrance with a 6,500 SF building expansion. The existing surface lot adjacent to the main building entrance will be reconfigured and relocated slightly east of its current location. Soil boring tests performed since the Commission meeting determined infiltration will not work on this pond. Reducing the impervious area on site by 0.74 acres and installing a SAFL‐Baffle weir in the storm sewer system will combine to meet the Commission standards for this site. The project was approved by the Commission at their May meeting pending the SAFL‐Baffle weir being covered by an easement and the appropriate operation and maintenance agreement being obtained and recorded with the property. The applicant’s agent indicated the O&M plan has been submitted to Rogers for approval.

2015‐013 Wayzata High School, Plymouth. An application for the Wayzata High School addition and expansion was received on April 29, 2015. The plan includes additions to the Wayzata High School building, new and/or expanded parking areas, new driveway, new playing fields, and new and/or modified stormwater ponds. The total disturbance area is approximately 44 acres, of which approximately 22 acres will be new impervious area. Staff met with the project engineer on May 28 to discuss the project, and Staff is working with the engineer to complete the necessary revisions.

Findings;

1) A complete application was received April 21, 2016. The initial statutory project review deadline is May 20, 2016.

2) Existing land use on this property is about 19 acres of cropland and 3.7 acres of wetlands. Proposed land use is institutional with 5.93 acres of impervious cover on the north side of the property.

3) The existing wetland receives considerable runoff from the east, and discharges west via culvert under Mohawk Drive. The runoff from his site eventually reaches Medina Lake. There will be a small amount of pervious runoff directed to the north.

4) Stormwater treatment will be provided by a NURP pond, equipped with a filtration basin, located on the west side of the property. In addition to this pond, the proposed plan will have a 575-ft long, 12-ft wide and 3-ft deep bio-swale that will discharge into the NURP pond. Another 250-ft long bio-swale will be built on the west side of the site. Filtrated water from this bio-swale will be discharged into the wetland and the overflows will be directed to the NURP pond. The site will also create three bio-trenches with filtering and infiltration capabilities on the northwest side of the complex. These trenches will daylight into the bio-swale located on the west side. Due to the low permeability of the native soils, there will be modest infiltration benefits from the proposed BMPs.

Stormwater Management

Runoff Rate Controls meet the Commission’s standards. 5) Existing and post-development peak runoff rates were modeled by using the Atlas 14, 24-

hour rainfall events for the 1-year, 2-year, 10-year and 100-year storm frequencies with the HydroCad program. Post-development runoff rates will be less than the existing rates.

Existing 13.05 14.09 17.80 25.31 Proposed 2.05 2.63 4.56 8.49

Item 5c-p


6) All stormwater treatment facilities must have drainage and utility easements placed on them. This includes the bio-trenches, bio-swales, NURP pond, wetlands and buffers and the west bypass storm sewer. All the storm water maintenance structures have access for maintenance purposes.

7) The developer is assuming the responsibility of the operation and maintenance of the stormwater treatment facilities and the buffer areas. A draft Development Agreement has been submitted but not reviewed yet.

Volume Controls meet the Commission’s standards. 8) 1.1” of abstraction over new imperious areas is required. The proposed project will create

about 5.934 acres of new impervious surface. This requires 23,678 cubic feet of abstraction (0.544 acre-feet).

a) About 3,945 cu-ft will be infiltrated through the bio-filtration trenches located between the buildings on the northwest side of the development. These trenches will incorporate 18-inch deep crushed rock below the filter soil mix and the drain tile to provide slow infiltration between the storm events. Infiltration volume is limited due to the slow permeability (0.10 in/hr.) of the underlying soil. These trenches will have a filtration capacity of about 5,200 cu-ft.

b) About 1.665 acres of buffers and north and west side of the site will be modified with amended soils (49,488 square feet within the buffers and 23,040 square feet on the north and west side of the site). These areas will get 0.5 inches of abstraction credit over the amended areas. This is equivalent to 3,022 cu-ft of abstraction.

c) Total abstraction credit available is 3,945 + 3,022 = 6,967 cu-ft.

d) The balance of the abstraction requirement, 16,711 cu-ft (23,678 - 6,967) will be met the filtration of stormwater through two bio-swales (west and west side), and a filtration bench constructed around the NURP pond.

e) The west bio-swale, 575 feet long, 12 feet wide and average of 3 foot deep, will be constructed along the west side of the fire lane. The swale will have four 2-ft high rock check dams to slow the runoff and to allow more time for the runoff volume to filter through the compost/sand mixture. There will be a 6-inch drain tile at the bottom of the filter medium. The drain tile will daylight at the north end of the NURP pond. This bio-swale will have a filtering capacity of about 7,000 cu-ft, including the storage capacity behind the check dams.

f) The east bio-swale will be about 275 feet long and will have a filtering capacity of about of 3,250 cu-ft. The filtered water will be discharged into the wetland, whereas the overflows will be conveyed to the NURP pond by an overflow pipe.

g) The filter bench around the NURP pond has a filtering capacity of about 20,000 cu-ft during a 1-year event.

h) A proposed irrigation system to irrigate about 3.2 acres will withdraw about 11,700 cu-ft per week of stormwater from the NURP pond. That is equivalent to about 0.5 foot of drawdown at NWL.

Item 5c-p


i) Summary of volume control management: The project requires 23,678 cu-ft of abstraction and provides 18,667 cu-ft through soil amendment, infiltration and irrigation. For the balance of the abstract requirement 35,450 cu-ft of stormwater will be filtrated before discharging into the NURP pond.

Required abstraction = 23,678 cu-ft Credit by soil amendment = 3,022 cu-ft Infiltration credit = 3,945 cu-ft Irrigation credit = 11,700 cu-ft (per week)

Net abstraction credit = 18,667 cu-ft Filtration credit = 35,450 cu-ft

Water Quality meets the Commission’s standards.

9) The proposed NURP pond will provide about 66% nutrient treatment, without taking into account the upstream filtration trenches and bio-swales. There is an additional a quarter acre-feet per week of irrigation withdrawal from the NURP pond.

The predevelopment phosphorus load is estimated as 22.63 lbs/year. Post-development load without any BMPs would be about 37.88 lbs/year. About a quarter of the post-development load will be removed due to the irrigation

withdrawal (irrigation volume is about ¼ of the 2-year event runoff volume.) Another 25% reduction is assumed due to the upstream infiltration and filtration

BMPs. The NURP pond is designed to remove about 66% of the incoming load, assuming no

upstream load reduction. Based on these assumption, the post-development nutrient load is estimated as 9.1

lbs/year. 10) The Stormwater Quality and Volume Summary Table below shows the pre- and post-

Grading, Erosion and Sediment Controls

11) Revised plans meet the Commission’s standards.

Floodplain

12) There are no designated floodplains within this site. Buffers

13) The Commission rules require 25 feet of average, 10 feet minimum buffer width around all wetlands. Buffers graded steeper than 1V:6H slopes require extended buffers, depending on the final grade. Based on that, the project needs to have about 66,000 square feet of buffer area. The proposed replacement plan provides about 70,000 square feet of buffers. All the wetlands and buffers will be placed under protective easements and covenants. The buffers meet the Commission’s standards.

Wetlands

14) City of Medina is the LGU in charge of administering the Wetland Conservation Act within their city boundary. The proposed project is proposing about 1.39 acres of wetland impacts. The replacement will be done on site by creating new wetland on the southwest side of the property. About 4.31 acres of area will be under wetland and buffer easements for a net wetland credit of 2.78 acres. The replacement plan was approved by the city.

Recommendation:

Staff recommends the approval of the revised plans with the following condition.

A final Stormwater Maintenance Agreement, including all the reviewed and approved BMPs (buffers, pond, bio-filters, bio-swales and soil amendment), shown on a plat map, must be submitted, and recorded. Hennepin County Department of Environment and Energy

Water Resource Name RushCreekActivityDescription The City of Maple Grove is proposing a project to stabilize and restore approximately 4500 feet of Rush

Creek north of 101st Avenue to decrease the potential for further bank instability that likely would occur subsequent to the development of the watershed and restore the channel with native vegetation for additional stability and habitat purposes. Subsequent to development, it is likely that stormwater discharge from the adjacent and upstream watershed will increase. This project will significantly reduce the potential for bank erosion and sediment transport downstream. The restoration of native vegetation will provide a habitat for wildlife and a natural area for aesthetic value and study.

Water Resource Name FishLakeActivityDescription The project will involve carrying out a batch alum treatment in Fish Lake to combat internal phosphorus

loading. We anticipate that the application would be carried out in two phases, separated by 3‐5 years depending on the results of an interim assessment to determine the effectiveness of the initial phase in controlling phosphorus released from the lake’s bottom sediments. It is expected that internal load control efforts will be combined with long‐term efforts to further reduce watershed loading as well through separate efforts by the City of Maple Grove and TRPD.

Projects&ActivitiesBudget $300,000.00 Action or Objective (from plan) Table 4.5 of Third Generation Plan. The purpose of the project is to control internal loading in Fish Lake to a sufficient degree so that the lake consistently meets the applicable state water quality standards for eutrophication over the long term. The TMDL

Item 9a


work completed for Fish Lake indicates that almost 70% of the phosphorus load driving surface water quality in the lake comes from internal sources. Fish Lake will be the main water body impacted by the project, but Rice Lake which lies immediately downstream will also benefit to a minor degree.

Mississippi River Shoreline Stabilization Champlin, Project #2016-006

Project Overview: City of Champlin is proposing the Mississippi River Shoreline Stabilization and Appurtenant Work between the Mississippi Point Park (confluence of Elm Creek and Mississippi River) and upstream of the TH 169 Bridge (near Colburn Street) along the south bank of the Mississippi River. Our review will be for compliance to the Commission’s 3rd generation SWMP requirements on erosion and sediment controls. Applicant: City of Champlin, Todd Tuominen, 11955 Champlin Drive, Champlin, MN 55316. Phone: 763-923-7120. Email: [email protected] Agent/Engineer: Same as Applicant. Exhibits:

1) Project 2016-006 ECWMC Request for Plan Review and Approval received March 4, 2016.

2) Project review fee of $550. 3) Pre-con meeting Minutes February 12, 2016. 4) Site plan, hard copy and electronic files (8 sheets):

Sheets include the Title Sheet, Details, East River Parkway, Mississippi Point Park, Colburn Street N. Plan sheets are dated December 14, 2015, and signed by Timothy Hanson, P.E.

Findings;

1) A complete application was received on March 10, 2016. The initial 60-day review period expires May 11, 2016.

2) Rule D. Stormwater Management does not require a review for this project. The plan proposes no new impervious area.

3) Rule F. There is FEMA floodplains within the project corridor. However, the stream restoration work will use riprap and bioengineering methods along the receded streambanks of the Mississippi and cause no net loss of floodplain conveyance or storage.

4) Rule G. Wetland Alteration. The ECWMC is the LGU in charge of administering the MN Wetland Conservation Act in the City of Champlin. The project stays below the DNR OWH and therefore the WCA is not applicable for this project.

Mississippi River Shoreline Stabilization Page 2 Champlin, Project 2016-006 April 15, 2016.

5) Rule I. Buffer Strip requirements. New development along the Mississippi River would require 25 feet buffer. Commission does not require buffers for appurtenant work. All the remaining streambank restoration work will be within the city-owned properties. Historically, the Commission has not required buffer within the city-owned properties..

6) Rule E. Erosion and Sediment Control will meet the Commission’s requirements. SWPPP narrative addresses NPDES permit requirements. Perimeter erosion controls are designed to isolate the restoration area and contain sediment. Permeant vegetation restoration is specified according to MPCA requirements.

Decision: Approved.
