Plains replace Drains: Native plants,
grasses to divert rain from drains, sewers
By Matthew B. Byerly
City and county officials gathered together at the
Porter County Jail August 19 to plant the seeds of a new
idea.
It was not a brainstorming session, nor one of the
plethora of budget sessions currently going on
throughout the region. Instead, it was a unique
ceremonial groundbreaking for the Stimson Drain
demonstration project. The $125,000 project will use the
jail property to show alternative ways for handling
stormwater runoff. Under a tent erected at the site due
to threatening skies, the earth was tilled and a variety
of native prairie perennial plantings were installed,
representative of the plant varieties to be installed
throughout the project.
The project is the unique brainchild of cooperation
between Valparaiso City Engineer David Pilz and
consulting firm J. F. New and Associates. Working
through a study funded by the city Redevelopment
Commission, goals were set to find “alternative best
management practices” that would improve storm runoff
quality before it reaches the aquifer tapped by the city
water department.
“Most of us, when we think of drainage, we think of
sewers and detention ponds,” said Pilz. “Our children
will talk about rain gardens and mesic prairie
depressions. It's a change in our culture, and I'm
excited to get it started in this area. Hopefully, this
idea blooms in other areas.”
The ceremony marks the start of a larger project funded
through a series of matching grants from the Lake
Michigan Coastal Program, funded by the National Oceanic
and Atmospheric Administration administered by the
Department of Natural Resources (DNR). Specifically, the
demonstration/study planting at the jail focuses on the
type of sandy soil found in the Stimson Drain area south
of US 30. Underground plastic ‘rain-store’ columns will
help collect and channel roof runoff to the
demonstration gardens. Other parts of the project
involve channeling water from the parking lot into
graded swells that will have water-absorbing native
plants. Wetlands, rain gardens and other features are
all designed to hold and treat the stormwater on the
jail site rather than releasing it into the Stimson
Drain, an area plagued by stormwater flooding in the
past.
Stormwater Management Board President Mark Reshkin hopes
that the project, despite a limited scope, will speed
development of techniques to manage water flow in areas
with silty or clay soils. Citing a recent report that
said US population will exceed 400 million within 50
years, Reshkin said that would mean covering much more
land with buildings and pavement, necessitating creative
ways of dealing with stormwater.
“This is a wonderful start, but we need to continue to
expand our vision,” he said. “Much of the land around
here that is built on for residential expansion is on
clay, not sand, and our work isn’t done until we can
handle both hand in hand with the environment.”
County Commissioner David Burrus and Valparaiso Mayor
Jon Costas also each made brief remarks during the
ceremony, focusing on the importance of cooperation
across governmental entity and party lines. Both men
cited the vision of Pilz and the cooperation from the
DNR as tremendous and important to the future of the
greater community.
DNR representative Jenny Kintzele shared officials
excitement and optimism.
“This truly is a step up from the normal,” she said. “I
wish all the projects we helped to fund and start were
so hands-on and progressive. Valparaiso is really a
community with a vision, and to see the cooperation
between the city and the county for the benefit of both
is truly rewarding.”
Kintzele also praised the public educational opportunity
surrounding the project. Pamphlets describing the
project are available for people interested in using the
techniques in other areas, and a sign will be placed at
the site, explaining the various features and showing
where they are located.
After remarks were through, officials each took turns
playing in the dirt, often to the good-natured chides of
their colleagues. As Sheriff David Reynolds was
preparing to plant some marsh milkweed, Chief Deputy
David Lain chimed in that the plant looked similar to
cannabis (marijuana). Similarly, as Burrus dug a hole,
Costas joked that the planting was above a Northern
Indiana Public Service Company power line. Both remarks
were met with laughs.
Plantings from the ceremony were only temporary,
however. They will be removed and replanted after J. F.
New and Associates complete regrading work for the
project, which began August 23. The firm will continue
to revisit and maintain the property as the plantings
develop into a full prairie scheme over the next three
years. Pilz said that though a consulting firm is
handling initial plantings and maintenance, he could see
the city horticulture department, a branch of the
Valparaiso Parks, wishing to watch the project closely
and aid in harvesting seeds for use in other plantings.
Meanwhile, the city will continue to track the
differences in runoff collection by watching the same
sites earmarked for the preliminary study, to provide a
comparison between past and future runoff collections.
“This is an ongoing project,” said Pilz. “We are dealing
with a living piece of engineering, and I think it’s a
great step.” |
