Green Tier Clear Waters Initiative Charter

2017 Annual Report

The Charter

The Green Tier Clear Waters Initiative (GTCWI) is a charter authorized under the laws of the State

Wisconsin, Act 276, sections 299.83 and 299.85 Wisconsin Statutes. The GTCWI was formally signed

by all parties on February 9th, 2006 and renewed in 2011 and 2016 by unanimous agreement of the

signatories.

Mission Statement

The mission of this Charter is to cause a meaningful reduction, beyond current state standards, in the

sediment and nutrient delivery to lakes, streams, and wetlands in Dane County resulting from land

disturbing activities and to develop alternative approaches and practices that will result in better erosions

control and long-term stormwater management. Furthermore, the mission is to explore new business and

regulatory practices that result in improved regulatory certainty for Charter Participants and increased

regulatory efficiency by regulatory agencies.

The Charter Signatories will explore the development of practices that minimize the environmental

impact of developments. This effort will focus on sustainable practices and will include measures for 1)

conservation of surface water and groundwater; 2) conservation of energy; 3) reduction of air emissions;

and 4) maximizing recycling.

2017 Summary

In 2017, the Charter’s Board of Directors met 8 times – February 9, April 06, May 25, July 6, August 17,

September 28, November 9 and December 21. The agendas from the meetings are attached. The Board’s

focus remains on construction site erosion control.

The signatories continue to find value in the Charter for the exchange of technical information and ideas.

They value the single point of contact within each entity. They appreciate the ability to affect change

whether in a product, a technique or regulatory standard.

The Charter signatories and our regular attendees are sincere in their efforts to influence not only the local

erosion control and stormwater management standards but statewide standards to improve water quality.

The Charters’ standards are being accepted by others and have proven to perform better than other

currently accepted practices. This year, GTCWI’s efforts included:

signatories’ outreach.

the annual compliance inspection of construction sites that shows signatories’ sites in compliance

more often than non-signatories.

multiple discussions on chlorides affecting area groundwater and use reductions.

the media-filled tubular geotextile review.

the Fall/Winter terrace cover pilot.

the continued commitment to the permeable surfaces test plot maintenance and research

NOI processing times.

1. Mission Statement Reassessment, 2017 Goals Progress Assessment and Establishment of 2018

Goals

In the process of Charter renewal and at our annual review, the signatories agreed that the mission

statement remain the same. It was agreed that the Signatories would continue the goal reflecting the

groundwater conservation, energy conservation, air emissions and recycling as they relate to the

2

Charter mission statement but the primary goal is erosion control to improve water quality of our

lakes and streams. Additionally, GTCWI intends to continue most of the 2017 goals into 2018, with a

few modifications.

Goals for 2017:

GOAL 1: Continued outreach to potential new members of the charter. Outreach efforts in 2017

will continue to target specific individuals & municipalities and will include personal invitations to

Board meetings. Grow Charter by one signatory.

2017 Progress: No new signatories were added in 2017 but we continue to attract interested parties

to our meetings and some return on a regular basis. A Department of Safety and Professional

Services’ Unified Dwelling Code staff and the City of Fitchburg’s Environmental Project Engineer

were frequent attendees.

GOAL 2: Complete annual inspections comparing compliance between sites of Charter members

and non-Charter members.

2017 Progress:

Completed. The results show that GTCWI signatories’ sites have better erosion control than non-

members.

Total Sites Inspected 21

Inadequate: 32%

Green Tier Overall Lot‐level Rating

Adequate: 100%

Inadequate: 0%

Non‐ Green Tier Overall Lot‐level Rating

Adequate: 22%

Inadequate: 78%

GOAL 3: Participate in educational seminar(s) or webinar(s) of BMPs for a professional audience.

2017 Progress: GTCWI signatories participated in a number of educational seminars including:

Vegetated Swale Technical Standard Committee

Waterways News letter

Saltwise partner

Rain Garden Construction Workshop

Sennet Elementary School - Rain Garden Construction

Elvhjem Elementary school- Rain Garden Construction

Permeable Surfaces Tour- MaMSWAP

Draft DNR Leaf Guidance was released based on the USGS, City of Madison Leaf Study

results.

GOAL 4: Continue discussion on how the Charter group can provide a greater focus on all of the

objectives defined in the mission statement (energy conservation, air emissions, recycling, etc.).

2017 Progress: The Charter signatories continue to identify and implement ways to improve their

energy conservation, air emissions and recycling. This goal wasn’t an agenda item this year but

occasionally the subject matter is incorporated into other issues. For example, the City of Madison is

now using LED lights for arterial street and has a solar installation program.

GOAL 5: Signatories will tour a construction site to view stormwater management and erosion

control practices; and a business associated with these practices.

2017 Progress: The signatories toured construction sites during the annual compliance monitoring

and visited the pervious surfaces test plot.

GOAL 6: Improve the products and practices that the signatories use through continued involvement

in development and piloting of new standards or practices.

a. Signatories will continue to support and participate in the Permeable Pavement Technical

Standards Council and on-site study.

2017 Progress: The permeable surface test plot was reconstructed in 2017. A tour of 9 sites in Dane

County was held on ( 6/27/2017). 30 people participated in the tour.

Bill Selbig of the USGS discusses the test plot and results. Then a water truck showed the pavement

in action.

b. Evaluate the piloted Fall terrace practices for winter and spring construction.

2017 Progress: Veridian Homes developed and GTCWI signatories are piloting and evaluating new

practices that are installed in the Fall so that while construction continue in the winter, winter and

spring runoff will not increase. Evaluation continues. The practice appears to be successful.

The pilot consists of placing rock in the terrace. Contractors accessing the site drive over the

‘tracking pad’. The terrace also catches runoff from the lot.

Additionally, signatories also participate in the Vegetated Swale and Exit Control technical standards

committees and on-site studies.

GOAL 7: Maintain open communication related to adaptive management issues and explore areas

for cross coordination.

2017 Progress: Signatories are participating in a number of different adaptive management/cross

coordination issues including Yahara WINs (Watershed Improvement Network), the Rock River

Coalition’s stream monitoring and the Clean Lakes Alliance Community Board.

5

GOAL 8: Review and modify the combined Municipality/DNR 30 Waterways and Stormwater

Permitting for GTCWI signatories.

2017 Progress: No progress was made on this goal. Appendix 6 describes a process that has never

been implemented. For several years, DNR’s Stormwater Program staff and the Waterway and

Wetland Program staff have been giving signatories’ applications priority for quicker processing.

Goals for 2018

GOAL 1: Continued outreach to potential new members of the charter. Outreach efforts in 2018

will continue to target specific individuals & municipalities and Organization and will include

personal invitations to Board meetings. Grow Charter by one signatory.

GOAL 2: Complete annual inspections comparing compliance between sites of Charter members

and non-Charter members.

GOAL 3: Participate in educational seminar(s) or webinar(s) of BMPs for a professional audience.

GOAL 4: Continue discussion on how the Charter group can provide a greater focus on all of the

objectives defined in the mission statement (energy conservation, air emissions, recycling, etc.).

GOAL 5: Signatories will tour a construction site to view stormwater management and erosion

control practices; and/or a business associated with these practices.

GOAL 6: Improve the products and practices that the signatories use through continued involvement

in development and piloting of new standards or practices.

a. Signatories will continue to support and participate in the Permeable Pavement Technical

Standards Council and on-site study.

b. Review and make recommendations to the manufacturers of framed inlet protection bags.

c. Evaluate the piloted Fall terrace practices for winter/spring construction.

GOAL 7: Maintain open communication related to adaptive management issues and explore areas

for cross coordination.

GOAL 8: Review and modify the combined Municipality/DNR Chapter 30 Waterways and

Stormwater Permitting for GTCWI signatories.

2. Assessment of Charter agreement

The signatories renewed the Charter in 2016. The current Charter is on the website.

3. Assessment of Appendixes

The signatories reviewed and updated the Appendices in 2016. Appendix 6 needs to be modified to

meet the signatories’ needs as well as being able to be implemented by DNR staff.

4. Assessment of Board operating procedures

a. Chairperson election – Jeremy Balousek, Dane County and Phil Gaebler, City of Madison, will be

the Board Co-Chairs for 2018.

b. Frequency of meetings – The Board agreed to continue to meet at the frequency of every six

weeks on Thursday mornings.

6

5. Recommendations to the Department for improvement

Our Charter continues to recommend that Green Tier should be available to and encouraged in all

state agencies. We have made this recommendation several times before and still feel it is valid.

Dane Co. Permeable Pavement Tour – June 27th, 2017

SMALL ACTIONS MAKE A BIG DIFFERENCE

Promega Corp. da Vinci Building- 5511 Bjorksten Place, Fitchburg Promega’s da Vinci building in Fitchburg was completed in early 2014. The building houses the tools and personnel needed to provide facility services to Promega’s main campus and branches. The project included two areas of permeable pavers (see photo). Permeable pavers were chosen instead of pervious concrete or porous asphalt primarily because of aesthetics. The da Vinci project was primarily a redevelopment project, but included some new impervious areas. The site is within the watershed of a regional, public stormwater management facility, but the regional facility does not provide full treatment for new impervious, specifically it does not provide 80% sediment removal. The regional facility does provide the required treatment for redevelopment standards. Permeable pavement was used to reduce the amount of new impervious area added to the site so that stormwater management requirements for new development were not triggered, just redevelopment standards. The permeable paver design included a bedding course directly under the pavers, a layer of AASHTO No. 57 stone over a minimum 6” layer of AASHTO No. 2 Stone subbase. The design included an underdrain as well as a 2’ deep storage layer under the underdrain. During installation of the eastern area of permeable pavers, the landscape contractor inadvertently used a sand filler which became impervious when exposed to water. The contractor had to chisel out the impervious filler and reinstall the correct filler material. The permeable pavers have not required maintenance to date. According to Promega personnel, the pavers have been holding up and performing very well.

Permeable paversPermeable pavers

Fearings Audio- 722 Walsh Rd., Madison Permeable asphalt is located on east and west side of the building. Permeable was used to meet stormwater requirements, but also allowed contractor to flatten out grade on east side of building. The design meets current permeable pavement standards. It’s a heavily used site installed about 3 years ago. Owner performs regular maintenance including: vacuuming, washing, leaf blowing and sweeping. Permeable asphalt used on left side of picture (left) and drive, parking on right is on standard asphalt. The photo to the right was taken during an intense rain event.

Permeable Pavement Test Site- Sycamore Ave., Madison USGS is currently leading a study to measure performance of permeable pavement. The study site was built in the summer of 2014 adjacent to the overflow parking lot serving the Madison Streets Division East Office on Sycamore Rd. The study area is split equally into three smaller study plots, each receiving similar volumes of runoff from the adjacent parking lot. These plots test three types of pavement: permeable pavers, permeable concrete, and permeable asphalt. Each plot is equipped with instrumentation to measure reductions in runoff volume (water quantity) and pollutants (water quality). Both the concrete and the pavers were replaced during the summer of 2016. Maintenance was also performed using a street cleaner in April 2016. The study is scheduled to continue through 2018. For more information visit https://www.usgs.gov/science/evaluating-potential-benefits-permeable-pavement-quantity-and-quality-stormwater-runoff?qt-science_center_objects=1#qt-science_center_objects

Quarry Vista Porous Asphalt Path- Fitchrona and Lacy Rd., Fitchburg (adjacent to Elan Apartments) The Quarry Vista plat Phase 1 improvements included approximately 825 lineal feet of porous asphalt multi-use path and 240 lineal feet of standard (impermeable) asphalt path, adjacent to Lacy Road and Fitchrona Road rights of way, around the south and west sides of the Elan Apartment site. The paths were installed in September, 2016. Porous asphalt was chosen to be consistent with the other public multi-use paths within the plat, which are asphalt per Fitchburg standards. Permeable pavement was used to meet stormwater management requirements because of the difficulty of routing the runoff from the path to a stormwater facility for treatment. The design included 3” of porous asphalt over a 12” minimum open graded base storage reservoir. It did not include an underdrain. The original design included porous asphalt for the entire length along Lacy Road. Prior to construction, steeper areas were reevaluated and changed to standard (impermeable) asphalt to minimize concerns over sub-base preparation.

Lexus Dealership - 8000 Airport Rd., Middleton Permeable asphalt was installed in 2005 on the north side of the dealership prior to any permeable pavement standards. The project includes a 4’-5’ deep aggregate storage layer with drain tile below the pavement. Little maintenance has been done on the site other than normal lot cleaning. Surface condition is fair and the permeable pavement is still performing though at a reduced level of efficiency. The photo on the right was taken during a moderate storm event.

City of Fitchburg Library- 5530 Lacy Rd, Fitchburg Permeable asphalt was installed in spring of 2010 on the west side of the library off Research Park Dr. To date the City of Fitchburg hasn’t done much maintenance except for sweeping aggregate that has been coming off. City staff report that the permeable asphalt is still performing, but not holding up well. During the winter months maintenance staff clear snow off with a broom as it does not hold up to the snow plow.

SMALL ACTIONS MAKE A BIG DIFFERENCE

Pre-cast permeable concrete sidewalk - Southwest Madison The City of Madison installed a 75 foot section of pre-cast permeable concrete sidewalk with underdrain in an area on southwest the corner of Pilgrim and Homestead Rd. that was prone to flooding. Pre-cast (RePlenish by Spancrete) was chosen in an effort to eliminate the variability of traditional concrete installation. The pre-cast was installed in fall 2016 as a trial in only a few hours and city staff report that there hasn’t been flooding issues at this location since.

Stricker Park Basketball Courts- 7605 Voss Parkway, Middleton Permeable asphalt was initially installed on the right basketball court only at Stricker Park to try and reduce cracking that was common at this site with traditional asphalt. Permeable was installed around 2010 directly over the old courts. City staff report that the permeable held up so well that they eventually decided to replace the left basketball court with permeable several years later (2014). This is the only site on the tour where permeable was not selected specifically for its infiltration properties.
