Green infrastructure: the next chapter in water quality

Evan Pratt Washtenaw County Drain Commissioner

Evan Pratt
Washtenaw County Drain Commissioner

When water pollution control began in the 1970’s, the first target was industry – stopping discharges of chemicals into the waterways.  This was followed by addressing wastewater treatment, then mitigating the impacts of combined sewer overflow (CSO).  Most recently, pollution in stormwater has been targeted, with federal regulations for urbanized areas coming on line in the late 1990s.

People had realized that hard surface development led to flooding, and some of the first steps to regulate runoff also started in the 1970s.  First, management of stormwater addressed runoff rates, through means such as detention ponds, with the goal of maintaining pre-development conditions and preventing flooding.  This philosophy, however, often falls short.  Addressing only the runoff rate does not address total runoff volumes, which also can cause downstream damage.  Further, studies found that detention basins usually did not address runoff water quality.

As a result of the 40 years of work noted above, stormwater runoff from roads is now thought to be the biggest source of pollutants today.  While agriculture is in the news for phosphorous loads, roads bring us urban phosphorous from lawns along with over a dozen other common human toxins such as lead, cadmium, copper, iron, and nickel.  Research shows that if you can handle the first inch of rain running off of roadways, you can manage most of this pollutant load.  This philosophy is one of the key drivers behind Washtenaw County’s Stormwater Design Standards, which focus not only on controlling the rate of runoff, but also the quantity and quality of that runoff.

The goal of the program is to allow stormwater to soak into the ground to the extent possible.  This approach provides many benefits:

  • the developer often can reduce the land required for detention ponds and meet landscape requirements at the same time by using raingardens, bio-swales, and other green infrastructure
  • downstream streams experience less scouring, stream bank damage, and other water quality impacts,
  • cost savings result from the use of green infrastructure to handle stormwater instead of investing money in systems to convey or detain the runoff, and
  • natural environmental systems are used to the largest extent possible to do what they were created to do, such as routing rain into the groundwater table to cool it off and slow it down.

Data from the National Oceanic and Atmospheric Administration (NOAA) indicate that Michigan is experiencing heavier rains than in previously recorded times; rainfall totals and peak intensities are 10+% and 15+% respectively over the past 30 years, even greater over the past 55 years. More rain is falling because more falls when it rains, but the dry periods are longer too.  The use of green infrastructure such as rain gardens, bioswales, and infiltration beds help to absorb this additional rain with moderate investment.  Infiltration under roadways has also proven promising, especially where there is native sand or sand backfill for a utility.

To address these issues, the Washtenaw County Water Resources Commissioner started a robust public comment period in late 2013 prior to implementing the current Stormwater Design Standards in August of 2014 and will soon embark on a follow up opportunity to receive additional feedback on the program to help guide the future.   The Commission is bringing in a stakeholder group in the next couple of weeks to get input on modifications to what was adopted in 2014.  That has been a part of the overall plan all along – to implement based on a stakeholder group that included development consultants, developers, municipal consultants, and municipal officials, then to assume there would be a need for minor tweaks after a year or so of use.   The Commission is working with a user group from the applicant side and the municipal agency side, as the standards are adopted by most of the developing communities in Washtenaw County.

I have been very impressed by the reaction of the development community and the ability of the geotechnical engineering community to implement these design regulations.  Partnership from the geotechnical profession has been the critical foundation allowing  implementation to go as smoothly as possible – we couldn’t do this without firms like G2 offering value and turnkey consulting on infiltration feasibility.  Prudent developers have always performed soils investigations early in the project; now data from these inexpensive investigations deliver information to determine how the site can implement needed infiltration – a real benefit since sites are now required to provide 20 percent more detention if they do not infiltrate the first one inch.  At the end of the day, the sooner the owner knows about the soils on the site, the fewer surprises they will experience.  Most have learned to get soil samples before site purchase.

Other communities will be moving in this direction in the near future as well.  The Environmental Protection Agency (EPA) has provided guidance on requiring infiltration in the context of stream channel protection.  In turn the Michigan Department of Environmental Quality (MDEQ) is requiring infiltration for all urbanized areas through their Municipal Separate Storm Sewer System (MS4) permit program which is on a 5-year renewal cycle – Washtenaw was on year 2 of that cycle in 2014-15.  All urban counties and communities – including Kent, Macomb, Livingston, Calhoun, Oakland and Wayne – are already working on revisions to address this approach in their  permitting cycle.

In closing, I see the use of green infrastructure expanding in its role to reduce stormwater runoff.  In fact, we are very encouraged by research documenting the ability of vegetation to transform heavy clay into medium grade soils with absorptive abilities.  The County currently is providing technical support to over 300 rain gardens.  I am planning to take this program to the next step, working with developers to use green infrastructure in place of ponds (as long as it performs) to handle stormwater.  We are currently developing the science to back this approach.

Unique Shaft System Facilitates Rehab of Interceptor

Jason Stoops, P.E Ann Arbor Office Manager

Nicholas A. Berkholz, EIT
Project Engineer

The Oakland-Macomb Interceptor Drain (OMID) is a 50-year-old concrete system bordering Oakland and Macomb Counties in southeast Michigan. Authorities targeted more than seven miles of this large diameter interceptor sewer – 40 feet below a busy county road (M 59) – as a priority for evaluation and repair to avoid catastrophic failure.  This project is part of a $160 million effort that has been under construction since 2009.  Given the unique opportunity the project afforded to have access to this critical trunk sewer, the owner’s objective was to perform as many repairs possible.

Lanzo Trenchless Technologies was selected to  provide multiple rehabilitation services, including  high volume sewage control management, cementitious grout in place liners, fully deteriorated model CIPP, large bore spot repairs, cementitious grouting of voids, access manhole restoration, localized crack/failure repairs using chemical grout and CCTV.  Challenges included working in and around flow that could not be disrupted during the construction process.  Work was difficult and dangerous, and required extreme care in safety consideration, monitoring and management.

One of the first tasks of the project was to tunnel a shaft down to the 96-inch diameter sewer crown, create access and build a platform for staging of both the chemical and cementitious grouting activities within the pipeline. Lanzo retained the services of G2 Consulting Group to design two 16-foot diameter corrugated steel liner shafts to gain access to the existing sanitary interceptor approximately 20 to 25 feet below ground surface.  To meet project requirements, G2 designed a shaft system that is uncommon for this part of Michigan.

2015 Was a Great Year – 2016 Looks Even Better!

Mark Smolinski, P.E Principal/Project Consultant

Mark Smolinski, P.E
Principal/Project Consultant

After years of slow to no growth in Michigan’s construction industry, especially road building, new construction projects took center stage here at G2 in Michigan in 2015, propelling us into our fourth consecutive record year.

One of the key 2015 highlights was the June acquisition of Birmingham (MI)-based Schleede-Hampton Associates, a former competitor, which will help the combined company expand its expertise as well as reach new industries and geographies.

During 2015, G2 completed a variety of projects for MDOT, including design build work with Dan’s Excavating and Bergmann Associates on the reconstruction of the I-75-University Drive interchange in Auburn Hills. The firm partnered with Hardman Construction to design and build the earth retention walls for the new $450 million Red Wings Arena in Detroit and worked with Giffels Webster and Scannell Properties on construction of the 60 acre, 300,000-sq-ft Fed Ex distribution center in Oak Park. In October, G2 was selected by RS Engineering to become part of the team for reconstruction of the I-94/Cadillac bridge in Detroit in preparation for the massive $3 billion, 20-year I-94 reconstruction project, slated to start in 2017.

Other 2015 highlights include:

  • The company was awarded a three-year “as needed” indefinite services contract by MDOT in January.
  • In June, G2 was part of the team that won the ASCE (American Society of Civil Engineering) Outstanding Civil Engineering Award for its work on the I-96 reconstruction project in Wayne County (MI) in 2014. This project also earned recognition by the Engineering Society of Detroit and CAM magazine as a signature construction project in Michigan.
  • In July, G2 was named one of the top 100 “Hot Firms” nationally by Zweig Group, a leading research, publishing and consulting firm in the AEP (Architecture, Engineering, Planning) and environmental consulting fields. The award is based on revenue growth over three years.
  • In July, G2 added two new equity partners – Mark Stapleton and Amy Schneider, both of whom had been with the firm for over a decade – to its top management team. During the year the company hired 13 new employees a 27 percent increase in staff for the year, and up more than 50 percent from just two years ago.
  • The firm completed more than 2,500 projects running the gamut from infrastructure, waste water, telecomm, health care, automotive and private sector work.

The jobs we won and the recognition we received made 2015 a very good year for G2 and positions us for an even better 2016.  Solving construction problems quickly and efficiently is our focus and we continuously reinvest in our people, our technology and our knowledge to ensure that we can meet whatever construction challenges we’re given. We look forward to successfully meeting more of those challenges and growing the business further in 2016.

Flickinger Elementary Conducts Concrete Testing at G2

Bruce J. Wilberding, P.E. Principal/Project Consultant

Bruce J. Wilberding, P.E.
Principal/Project Consultant

When the Academic Talented and Gifted (ATG) program at Flickenger Elementary (Utica, MI) decided to focus on construction this year, G2 was happy to get into “the mix.”

Rob Norris, a parent and employee at Pullman SST, suggested that the students mix concrete and take it to a testing facility to have it tested for strength. The 17 students mixed four different types of cement (1060 PSI and Mapei with and without Aggregate).

Samples of each type of cement were placed in testing tubes, which were taken to G2’s testing lab.  After a tour of the facility, students watched as the concrete they had created was tested. Each cylinder log was placed into a machine to see how much pressure it could withstand.  The whole process was an amazing learning experience for the ATG students and a lot of fun for G2.

New FedEx Facility @ Former Detroit Artillery Armory

Chris Nicol, PE/Project Manager

Chris Nicol, P.E.
Project Manager

FedEx Corporation will occupy a 300,000 square foot distribution center currently under construction on the former site of the Detroit Artillery Armory in Oak Park, Michigan. The property had included a 494,000-square-foot building that was a machine gun manufacturing plant during World War II, which has been demolished. The property then was turned over to the Michigan National Guard after the war for training and storage until the early 1990s, and then just for storage until 2000.

G2 Consulting Group was retained by Giffels Webster to perform a geotechnical investigation on the 60 acre site, which had varying depths of fill remaining from former uses. G2 characterized subsurface materials and developed deep and shallow foundation designs for consideration. After reviewing options, Scannell Properties, the construction developer, decided to remove and replace existing fill and construct shallow foundations. G2 now is working with Scannell Properties to perform QC during construction for earthwork, foundations, pavements, floor slabs and structural steel.
