IV.  Open Forum. 

  No one wished to speak to items not on the agenda. 

V.  Project Reviews. 

  A.  SC2017‐08 New Hope City Hall. Weber, Long, and Johnson presented an overview of this project which will come before the Commission for review. The project  includes construction of a new city hall and police building and future construction at Civic Center Park for the new pool and park areas. Underground storm water storage  and  treatment  is  planned  for  around  the  city  hall  site which will  be  reviewed  by  the  Commission  in November. The future construction items at Civic Center Park will be reviewed by the Commission in the future as the overall project progresses. The presentation discussed the next step and goals, which included exploring BMP options and funding opportunities with partnership from the Commission.  

    B.  WM2017‐009 Capstone Quadrangle Buildings A & B, Brooklyn Park.* Development of a vacant 12.4‐acre lot on a 20.2‐acre master site located at 9301 Winnetka Avenue North. The proposed site will consist of two buildings with associated parking and sidewalks, and expansion of an offsite  infiltration basin.   The basin  is included  in the master site. Following development, the site will be 82%  impervious with 10.1 acres of  impervious surface, an increase of 10.1 acres. A complete project review application was received on September 5, 2017. 

    To  comply with  the  Commission’s water  quality  treatment  requirement,  the  site must  provide ponding designed to NURP standards with dead storage volume equal to or greater than the volume of runoff from a 2.5” storm event, or BMPs providing a similar level of treatment ‐ 80‐85% TSS removal and 50‐60% TP removal. If a sump is used the MnDOT Road Sand particle size distribution is acceptable for 80% capture. 

  Runoff from the site is proposed to be routed through grass swales, 8 rain gardens, and 4 sump manholes with SAFL baffles before entering the east and west infiltration basins. Further water quality treatment is provided  through  abstraction  in  the  two  infiltration  basins  and  swale.  The  applicant meets  Commission water quality treatment requirements. 

  Commission rules require that site runoff be limited to predevelopment rates for the 2‐, 10‐, and 100‐year 24‐hour storm events. Most runoff is routed to the west infiltration basin on the western portion of the master site, and  then discharged  from  this basin  to a MnDOT basin associated with Highway 169. Some  runoff, however, drains immediately off site: Drainage Areas 13S and 14S, two relatively small areas on the northern and southern  edges of  the  site,  respectively, drain offsite  and  into municipal  storm  sewer  to  the north  and  south. (Volume of runoff to the north and south is less than existing conditions and amounts to 0.321 ac‐ft to the north and 0.077  ac‐ft  to  the  south during  the 100‐year  storm.) Overflow  from  the east  infiltration basins  also drains immediately offsite to the east. (Volume of runoff to the east is greater than existing conditions, and amounts to about 1.6 ac‐ft during the 100‐year storm.) The applicant meets the Commission’s rate control requirements for drainage to the north, south and west. Increased runoff to the east must be approved by the City of Brooklyn Park.  

  Commission rules require the site to infiltrate 1.0” of runoff from new impervious area within 48 hours. The new  impervious  area on  the master  site  is 655,753  SF,  requiring  infiltration of 71,040 CF within 48 hours. The applicant proposes to route runoff to Pond 2P, which has the capacity to infiltrate the required volume within 48 hours. The applicant meets Commission volume control requirements. 

  The NWI does not identify any wetlands on this site. There are no Public Waters or floodplain on this site.  The low floor elevations of the buildings are at least one foot higher than the high‐water elevation of the infiltration basins according to the HydroCAD model. The high‐water elevation of East Infiltration Basin 02 is exactly one foot lower than the low floor elevation of the buildings. The applicant meets Commission floodplain requirements.  

  An erosion control plan was submitted with the project review and includes a rock construction entrance, perimeter silt fence, slope checks, and native seed specified on the pond slopes. The erosion control plan meets Commission requirements.

  A  public  hearing  on  the  project was  conducted  on  September  11,  2017  as  part  of  Planning Commission and City Council review of this project, meeting Commission public notice requirements. 

  A draft operation and maintenance agreement has been provided to the Commission, and should be approved and signed by the City of Brooklyn Park.  

    Motion by Jaeger, second by Butcher to advise the City of Brooklyn Park that approval of Project Review WM201‐009 is granted with two conditions: 

    1.  The City of Brooklyn Park must  agree  that  increased  runoff  to  the  east of  the  site  is acceptable to municipal storm sewer. 

    2.  The  draft  operation  and maintenance  agreement must  be  approved  by  the  City  of Brooklyn Park. 

Motion carried unanimously. 

VI.  Watershed Management Plan. 

  A.  Skyway Park Cost Share Project.* In March 2017 the Commission approved an application from the City of Crystal for $50,000  in Cost Share Program funds to  install an underground  infiltration chamber  in the Skyway Neighborhood adjacent  to Crystal Airport. This project did not meet  the  threshold  for project  review or require installation of BMPs to meet Commission requirements. The area is tributary to Upper Twin Lake. The City installed a large infiltration tank on the west side of Skyway Park. It will hold 13,070 CF of water (97,000 gallons) which is enough to take a 2” rain event over the 1.8 acres of impervious area that drain to this location. The entire watershed area for this tank  is 4 acres. The project  is now complete and the City has requested reimbursement.  The total cost of this installation was $111,701.90. Staff recommends approval of this request. 

    Motion by Roach, second by Jaeger to authorize reimbursement of $50,000  in cost share funds for this project.  Motion carried unanimously. 

  B.  Spector  presented  a  preview  of  Wenck’s  presentation  at  the  upcoming  Water  Resources Conference entitled, The Importance of TMDL Adaptive Management: Lessons from Shingle Creek.

VII.  Water Quality. 

VIII.  Education and Outreach.* 

  A.  Native Plant Sales/Pledge to Plant.  At their October 10 meeting WMWA members and partners discussed strategies to increase the number of pledges. One option is to see if one or more Watershed Stewards would  be  interested  in  taking  on  and  potentially  implementing  as  a  project  development  of  a  community engagement plan. Engagement efforts to date have mainly used social media and websites in addition to tabling at the State Fair and a few community events. 

  B.  Watershed PREP. The educators are teaching and scheduling classes. On October 11 they will be doing a 6th grade program at Jackson Middle School for four classes of approximately 35 students each. This will be  the debut of  the 6th  grade program, which  is modeled on one used by Dakota County  SWCD.  Following  a presentation,  there  is a hands‐on activity where students  role‐play and demonstrate sources of water pollution and its effects on various biologic communities. 

  C.  Water  Links  E‐Newsletter.  Hennepin  County  has,  until  now,  published  this  e‐newsletter  and maintained the listserv as one part of their contribution to the collaboration. (They also provide publication layout assistance  and  print  brochures  and  other materials  at  no  charge  to WMWA  and  the  Commissions). WMWA generates newsletter content and then Hennepin County staff do the newsletter setup and send it out. Their staff have become increasingly unable to do this on a timely basis and WMWA has decided to take on this activity. Due to privacy concerns, Hennepin County cannot release the mailing list of over 2,200 subscribers, so the list will have to be rebuilt. The next e‐newsletter, which will be the  last published by Hennepin County, will  include a  link  for 

Item 1c

Joint SCWM Meeting Minutes October 12, 2017 Page 4  

Brooklyn Center • Brooklyn Park • Champlin • Crystal • Maple Grove • Minneapolis • New Hope • Osseo • Plymouth • Robbinsdale

folks to subscribe to the new e‐newsletter. WMWA will use a service such as Constant Contact or MailChimp for this, and there will be an annual expense of ~$1,500 for the subscription and staff time. 

  D.  Website/Social Media. The website Google Analytics  for September 2017 and  January 2017  to date are included in Staff’s memo, along with Facebook insights for the last 28 days for both the Shingle Creek and WMWA Facebook pages. As a  reminder, Reach  is  the number of  times a post was  viewed  in a Facebook  feed, Engagement  is an action  ‐ a click, comment, share, or reaction. There were only a  few posts  to  the FB page, so metrics are light compared to last month. 

  E.  The next WMWA meeting  is scheduled for 8:30 a.m., Tuesday, December 5, 2017, at Plymouth City Hall. Commissioners are encouraged to attend. 

  F.  A  flyer  promoting  Level  II  Smart  Salting  Training* was  included  in  the meeting  packet.    The training will be held October 17, 2017, at Plymouth City Hall, is intended for lead winter maintenance staff, and is provided at no charge.  For more information and to register: www.minnehahahcreek.org/level2salt2017. 

IX.  Grant Opportunities.   

  A.  With  the  closing  of  the DO  Aeration  Project,  the MPCA  has  requested  that  the  Commission return  unspent  grant  funds.  The  Commission  had  contracted  with  Forecast  Public  Art  to  manage  the  artist selection  process,  and  to  administer  the  contracts with  the  artists.  The  Commission  had deposited  funds with Forecast  to  reimburse  their  administrative  expenses  in  accordance with  the  contract  and  to  pay  the  artists  in installments for their work. Those deposited funds were a combination of grant funds and Commission levy funds. 

    Forecast  provided  an  accounting  of  their  expenses  and  the  payments made  to  the  artists  to develop their design concepts and the total balance of unexpended funds. The bulk of the unexpended funds were to be paid to the artists to actually produce their artwork, which did not occur.  Forecast has refunded $61,202.15, of which $34,530.73 was grant funds and $26,671.42 was levy. 

    The MPCA  had  requested  the  refund  as  soon  as  possible  so  it  could  be made  available  for another Section 319 project. The Commission Chair administratively authorized  release of  the check earlier  this month and now asks that the full Commission formally approve the release. 

    Motion by G. Anderson,  second by Sicora  to approve  the  release of unexpended  funds  in  the amount of $34,503.73.  Motion carried unanimously. 

  B.  Matthiesen presented preliminary data findings for the Biochar Project.

X.  Communications.  

  A.  September Communications Log.*

SHINGLE CREEK WATERSHED MANAGEMENT COMMISSION

PROJECT REVIEW SC2017-008: New Hope City Hall- Southern Drainage Area Owner: City of New Hope (Jeff Sargent—Community Development Director) 4401 Xylon Avenue North New Hope, MN 55428 763-531-5196 [email protected] Engineer: Chris Long Company: Stantec Address: 2335 W Highway 36 St. Paul, MN 55113 Phone: 651-604-4808 Email: [email protected] Purpose: Demolition and construction of New Hope’s City Hall, Police Station, City Pool,

and associated parking lot, as well as the reconfiguration of the park amenities in the project area. The total project area is about 19.8 acres.

Location: 4401 Xylon Avenue North, New Hope, MN 55428 (Figure 1). Work will take place on the following five parcels (all of which are owned by

the City of New Hope): • 1811821120005 • 0711821430004 • 1811821120002 • 1811821120001 • 1800821110011

Exhibits: 1. Project review application and project review fee of $2,200, received

10/26/17.

2. Site plan, preliminary plat, grading, utility, erosion control, landscaping plans and hydrologic calculations by Stantec, received 10/26/17.

Findings: 1. The proposed project is the demolition and construction of New Hope’s

City Hall, Police Station, City Pool and parking lot, as well as the reconfiguration of the park amenities in the same area. The site is 19.8 acres (Figure 2). Following development, the site will be 46% impervious with 9.1 acres of impervious surface, an increase of 1.7 acres.

The project is scheduled to take place in phases over the next several

years. The first phase will include construction of the new City Hall/Police Department building, minor alterations to the parking lot north of the new City Hall, and minor alterations to the secure parking area and driveway south of the new City Hall. Although roof runoff from the new City Hall/Police Department building will drain north, this permit application only includes a model for drainage to the south (about 3 acres, south of the new City Hall/Police building; Figure 2). Commitments for drainage to the north are discussed in item (12) below, and the model for drainage to the north will be submitted in a future project review.

Item 4a

2. The complete Project Review was received on 10/26/17. To comply with

the 60-day review requirement, the Commission must approve or deny this project no later than the 12/14/17 meeting. Sixty calendar-days expires on 12/25/17.

3. To comply with the Commission’s water quality treatment requirement, the

site must provide ponding designed to NURP standards with dead storage volume equal to or greater than the volume of runoff from a 2.5” storm event, or BMPs providing a similar level of treatment - 80-85% TSS removal and 50-60% TP removal. Commission rules also state that the water quality rule may be met if runoff from a 1.3” event is infiltrated or filtrated.

Runoff from about a third of the south drainage area (called South Drainage Area to Xylon) is proposed to be routed to an underground storage tank that filters stormwater before releasing it to the Xylon Avenue storm sewer (Figure 3). Runoff from a 1.3” event in this drainage area will be filtered in the underground storage tank, meeting Commission water quality treatment requirements. The remaining two thirds of the south drainage area (called South Drainage area to Fire Station) will not treat runoff from a 1.3” event, but very few alterations to this area are proposed, making treatment difficult. The applicant meets Commission water quality treatment requirements.

4. Commission rules require that site runoff be limited to predevelopment

rates for the 2-, 10-, and 100-year storm events. Runoff from the southern portion of the site is either routed into an underground storage tank that filters stormwater before releasing it to Xylon Avenue storm sewer, or is routed offsite to the south (Figure 3). During the 2-year and 100-year storm events, site runoff is limited to predevelopment rates, meeting Commission rate control requirements (Table 1). However, during the 10-year event, proposed runoff is greater than existing runoff by about 2 cfs (Table 1). Because much of the southern drainage area of the site is not being disturbed, the applicant is not able to regulate this increase in runoff. The applicant has sized the proposed storm sewer for this additional runoff and the City of New Hope has stated that the downstream sewer line has the capacity for the additional runoff. The applicant meets the Commission’s rate control requirements.

Table 1. Runoff from site (cfs).

Pre- Post- Pre- Post- Pre- Post- South 6.58 6.09 8.54 10.49 28.37 28.30

5. Commission rules require the site to infiltrate 1.0” or filtrate 1.3” of runoff

from new impervious area within 48 hours. As discussed in item (3) above, the applicant meets this requirement for the area called South Drainage Area to Xylon, but not for the area called South Drainage Area to Fire Station, due to the lack of changes proposed for the fire station area. The applicant meets Commission volume control requirements.

6. The NWI identifies a probable wetland on the northern portion of the site.

However, Bernie Webber, who serves as the WCA LGU contact for the City

of New Hope, stated on 10/31/17 that this is not a wetland. He said that the area has drainage issues, and is purposely flooded in winter for use as a general skating rink, but it is not a wetland.

7. There are no Public Waters on this site.

8. There is no floodplain on this site. The low floor elevations of the buildings

are at least two feet higher than the high water elevation of the underground storage tank, and street surface flooding will drain away from the new building, meeting Commission requirements.

9. An erosion control plan was submitted with the project review, and

includes rock construction entrance(s), inlet protection, silt fence and bioroll. The erosion control plan meets Commission requirements.

10. Several public hearings on the project have been conducted as part of

Planning Commission and City Council review of this project, meeting Commission public notice requirements.

11. A Project Review Fee of $2,200 has been received.

12. Drainage to the North: The majority of the disturbance will take place in

this area. Final designs of this area and the associated HydroCAD model will be submitted to the Commission for review when they are complete. The City’s commitments for the northern drainage area design, stated in this application, are as follows:

• Total impervious will be 9.1 acres (an increase from 7.4 acres). A total

of 6.1 acres will be treated.

• A HydroCAD model will be developed to ensure proposed runoff rates will not exceed existing runoff rates.

• An underground storage tank will be used to filter, at minimum, the

1.3” event.

• When the underground storage tank capacity is exceeded, water will overland flow to a greenspace that will act as a detention basin.

• The City may include water reuse BMPs.

• The City will evaluate the feasibility of routing runoff from the

neighborhood adjacent west (along Zealand Avenue) to the underground storage tank.

• Runoff will be routed to the stormwater pond on 45th Avenue.

Recommendation: Recommend approval with no conditions. Wenck Associates, Inc. Engineers for the Commission ____________________ ______________________________
