Highland Park ravine restoration improves drainage — and habitats

Posted on:

Chicago Tribune: August 28, 2013

by Gregory Trotter and Denys Bucksten

Experts hope the restoration of a ravine in Highland Park will benefit fish and other tiny aquatic critters.

Most ravines on the North Shore are mainly to drain stormwater into Lake Michigan. But Park District of Highland Park officials sought a tricky balance three years ago when they began improving the structural integrity of a ravine for runoff — while also making it easier for fish to swim upstream and spawn.

In partnership with other agencies, the park district secured a $200,000 federal grant to restore the habitat that drains water through Ravine Beach, also known as “Ravine 7.” (There are 11 ravines in Highland Park.)

As part of that restoration, elementary and high school students learned hands-on lessons about the way life in one ravine ecosystem can affect the water quality of Lake Michigan.

Many of those students had never even been in a ravine, despite growing up so close to one. Now some of them hope to change the world, one ravine at a time.

“It really opened up my eyes,” said Russell Friedman, a 19-year-old environmentalscience major at the University of Iowa. “I always liked being outdoors, but I never appreciated nature until then.”

In his senior year at Highland Park High School in 2012, Friedman took an environmental science class. Working with the nonprofit group Trout Unlimited, the class studied the ravine, took water samples and learned about micro-invertebrates. They began to see how development and years of environmental neglect had harmed the ecosystem.

“It opened my eyes to how much damage we were doing,” said Friedman, born and raised in Highland Park. “A lot of kids didn’t realize that.”

Most ravines along the North Shore used to be teeming with fish and aquatic life. But few could be restored like the one in Highland Park, said Charles Shabica, a coastline engineerwhose firm, Shabica & Associates, designed and engineered the restoration of the Highland Park ravine.

Because of development over the years, many of the ravines have been eroded by a drastic increase in stormwater runoff, Shabica said. Neighboring communities on the North Shore — such as Lake Bluff, Glencoe and Winnetka — work on their ravines, Shabica said. But those projects are more focused on protecting against erosion, less on environmental restoration.

“We’re living in a modified environment where, like a garden, we have to tend it a lot more,” Shabica said. “Before human beings, it didn’t need to be tended.”

The Ravine 7 project in Highland Park was funded by the federal Great Lakes Restoration Initiative, which began in 2009 when President Barack Obama signaled that restoration of the region was a national priority. The Alliance for the Great Lakes also supported the project.

Highland Park park officials saw an opportunity to reconnect the ravine watershed with fish species once abundant there — including chub, white suckers, rainbow trout, and the endangered long-nose dace.

Highland Park’s 11 natural ravines number more than in any community along the North Shore. The park district manages four of the ravine outfalls; the rest are a mix of city and private property, said Rebecca Grill, natural areas manager for the Park District of Highland Park.

On a recent walk in the ravine with students, conservationists, and U.S. Rep. Brad Schneider, D-Illinois, Grill further explained the project.

“We teach that everybody lives in a watershed and this particular watershed is draining about 375 acres of Highland Park, including parts of downtown, the area around the library and city hall,” Grill said.

In recent years, people have begun looking at ravines from a more environmental perspective, she said.

“What it does is tie into fish spawning seasons and if you go back 9,000 years people who lived here would actually spearfish the sucker fish that ran up into these streams. That was their protein; fish running into tributaries to Lake Michigan, all along the lakeshore and up into Wisconsin,” Grill said.

“Like many things, we’ve lost our connections with those sorts of things,” she said. “And most of the streams like this one that outfall at the lake are now blocked off.”

The mouth of Ravine 7 had been blocked by an unsightly concrete and steel barrier erected to protect sanitary sewer lines from breaking and contaminating the surrounding area.

To improve the ravine, the park district worked with the North Shore Sanitary District and the city of Highland Park to lower barriers at the outfall — a critical improvement to allow fish passage, Grill said.

Along the ravine, specialists built a system of pools and riffles — shallow gravel beds — effectively creating a “fish ladder” that allowed fish to swim upstream, rest, take shelter and lay their eggs.

Rounded boulders in the ravine allowed fish to move more freely and helped protect against erosion. Rock overhangs were constructed above pools to provide additional places for fish to hide, and to mimic natural cover such as tree roots that hang out shallow water.

As part of the grant partnership, the high school and elementary students participated in a Trout Unlimited education program called Trout in the Classroom, as part of their environmental science curriculum. The idea was to teach them about the ravine ecosystem and, more generally, to understand the natural science right in their backyard.

Besides the fish, the kids are the biggest winners of the restoration project, said Jim Tingey, of Trout Unlimited. The high school project culminated this spring in releasing fish that had been raised in the science lab into the ravine pools.

“It’s a lot different than holding an iPod,” said Tingey, a retired teacher, artist and fisherman. “When you look at them and see the look on their faces as they hold the fish … that’s why I continue to do this.”

Environmental restoration won’t work in all ravines, warned Jon Shabica — Charles Shabica’s son and vice-president of their Shabica & Associates. Some have eroded too much or are too steep for fish too realistically swim upstream. And the rounded boulders used for restoration cost nearly twice as much as blasted quarry rock, he said.

A prudent approach should be taken to determine whether the added expense is worth it in a given site, he said.

“It needs to be the right ravine to make it work,” Jon Shabica said. “A lot of times, structural stability is more important than environmental restoration.”

For some of the kids involved, the environmental work is just beginning.

“I felt good about myself being involved with nature in Highland Park and helping it get better,” said Dominic Ugolini, 18, of Highwood, who released trout into the ravine last spring.

Ugolini is a sophomore at Northern Michigan University now, pondering a degree in environmental science.

Meanwhile, Friedman is determined to follow in Grill’s footsteps and become a restoration ecologist.

He has his own ideas now about what needs to be done.

“They should try to keep it going as a project. … We have a lot of work to do in Highland Park,” Friedman said. “There are a lot of ravines on the North Shore.”

Long-Buried New Jersey Seawall Spared Coastal Homes From Hurricane Sandy’s Wrath

Posted on:

National Science Foundation Press Release 13-126: July 16, 2013

Built in 1882, then hidden by drifting sands, seawall mitigated 2012 hurricane’s effects

Picture two residential beach communities on the New Jersey shore: Bay Head and Mantoloking. They sit side-by-side in Ocean County on a narrow barrier island that separates the Atlantic Ocean and Barnegat Bay.

Before Hurricane Sandy landed on Oct. 29, 2012, a motorist traveling north would pass through Mantoloking into Bay Head. He or she would note few changes in residential development, dunes, beaches or shoreline.

The difference, however, was hidden under the sand.

A long-forgotten, 4,134-feet-long seawall buried beneath the beach helped Bay Head weather Sandy’s record storm surges and large waves, says geoscientist Jennifer Irish of Virginia Tech.

The stone structure dates to 1882. Its reappearance in 2012 surprised many area residents, underscoring the difficulties transient communities have in planning for future threats along their shores, Irish says.

“It’s amazing that a seawall built nearly 150 years ago, then naturally hidden under beach sands and forgotten, would have a major effect under the conditions in which it was originally designed to perform,” says H. Richard Lane, program director in the National Science Foundation’s (NSF) Division of Earth Sciences.

NSF funded the research through a rapid response award following Hurricane Sandy.

“This finding should have major implications for coastal planning, as sea level rises and storms increase in intensity in response to global warming,” says Lane.

The results, published online this week in the journal Coastal Engineering, illustrate the need for multi-levels of beach protection in coastal communities, Irish and colleagues say. Irish is the paper’s lead author.

“Once we got to the site, we immediately saw the seawall,” Irish says.

“The beach and dunes did their job to a certain point, then the seawall took over, providing significant dampening of the hurricane waves.

“It was the difference between houses that were flooded in Bay Head and houses that were reduced to piles of rubble in Mantoloking.”

With recovery efforts underway and storms still circulating through the area, Irish and Robert Weiss, also a geoscientist at Virginia Tech, along with Patrick Lynett, a civil and environmental engineer at the University of Southern California, assessed the area, documenting high water marks, damage, overwash and breaches of the barrier island.

All oceanfront homes in the two boroughs were damaged, ranging from ground-floor flooding to complete destruction.

As measured by waterlines in the interiors of homes, flooding was similar in both boroughs.

The difference was the extent of the storm’s effects.

In Mantoloking, an entire dune nearly vanished. Water washed over a barrier spit and opened three breaches of 541 feet, 194 feet and 115 feet, respectively, where the land was swept away.

In Bay Head, only the portion of the dune located seaward of the seawall was eroded. The section of dune behind the seawall received only minor local scouring.

Later, using Google Earth to evaluate aerial images taken two years before and immediately after Hurricane Sandy, the researchers looked at the area’s houses.

They labeled a structure with a different roofline as damaged, one that no longer sits on its foundation as destroyed and the remaining houses as flooded.

The scientists classified 88 percent of the oceanfront homes in Bay Head as flooded, with just one oceanfront home destroyed.

In Mantoloking, more than half the oceanfront homes were classified as damaged or destroyed.

Despite the immense magnitude and duration of the storm, a relatively small coastal obstacle–the seawall–reduced potential wave loads by a factor of two.

The seawall was the difference between widespread destruction and minor structural effects, the researchers say.

“We are left with a clear, unintentional example,” says Irish, “of the need for multiple levels of defense that include hard structures and beach nourishment to protect coastal communities.”

Additional researchers include Wei Cheng and Stephanie Smallegan of Virginia Tech.

Flying high with kite aerial photography

Posted on:

The Martha’s Vineyard Times: July 2, 2013

by Michelle Gross

Jon Shabica has found a way to combine an interest in photography and a passion for kite flying. He uses a GoPro camera to capture bird’s-eye views, most recently of Oak Bluffs.

A coastal engineer by profession from Illinois, Mr. Shabica said he’s always had a knack for photography.

“At home, when we photograph our projects, we’re typically shooting at low elevations that are maybe 20 feet off the ground,” he said.

He also has a passion for kites. “My father was a kite addict,” Mr. Shabica said. “So I’ve always been around kites. It was a big part of my childhood.”

While looking for creative ways to combine his talents, an idea dawned, and camera and kite in tow, he set out to do something different.

Using a Hero 2 GoPro—a lightweight high-definition camera with a protective waterproof case—Mr. Shabica sets the camera to fire continuously, every ten seconds within a specified time, and rigs it to the tail of his kite. Minutes later, with the kite soaring a few hundred feet in the air, Mr. Shabica waits anxiously to see what it would come back with.

“The first time I did it, I was blown away by how clear the pictures were,” Mr. Shabica said. “It’s one hundred percent to the credit of the technology. All I have to do is put it in the air. That’s the hard part.”

The timer can be set in two, five or ten second intervals. The camera is hung on a suspension system designed to keep it from spinning on the kite’s line. It is that simple.

A Chicago native and seasonal Oak Bluffs resident for the last 42 years, Mr. Shabica is the vice president of Shabica & Associates—a coastal engineering and consulting firm that helps build and restore beaches and ravines. Or, as he likes to put it, he “builds beaches.”

“Because my dad grew up out here, my family has always loved the beach. It’s fun for us, we love the water,” he said.

With a degree in medical illustration and photography from School of the Art Institute of Chicago, Mr. Shabica said his interest in aerial photography was born out of the necessity to survey the coastlines that he helps build. Now, he does it just for fun.

“It’s great for my line of work because I’m out on the water,” he said. “You get that unique perspective. But I don’t do it [kite photography] professionally.”

Although he has four kites of all shapes and sizes, his favorite is a six-foot-long inflatable penguin. “People are really drawn to this one,” Mr. Shabica said as he held the penguin kite pre-flight while standing in Ocean Park last week. The kite comes equipped with a large yellow beak and matching waddling feet. He affectionately refers to it as Betsy.

“The aim is to keep the line out of the camera’s sights,” Mr. Shabica said as he began releasing the kite’s spool. “But the picture from above is amazing.”

Mr. Shabica, now somewhat of a kite photographer aficionado, said some of his favorite photos are the ones where he can be seen in a part of the frame. A technique otherwise known as photobombing.

“I call it the Where’s Waldo factor,” Mr. Shabica said. “Although kids these days probably don’t know what that means.”

The kite’s flight time lasts no more than five to ten minutes and at its higest elevation can reach one thousand feet. But what goes up must come down, and among Mr. Shabica’s biggest concerns is safety.

“The challenge is you have to fly it over open areas, not over roads or crowded places. It’s a liability; I just don’t want to hurt anybody,” Mr. Shabica said.

How it works

There are several ways a camera can be attached to a kite. Typically, on kites like Betsy, a small and lightweight camera is secured to an adjustable rig and suspended from a line at a close distance. This distance helps reduce excessive movement between the kite and camera. The camera is also set to a high shutter speed to reduce motion blur. A wide-angle lens is preferable in order to achieve the maximum impact of each photo. Gravity helps to keep the rig level, irrespective of the angle of the kite line. Generally, single-lined kites are used, as they allow longer spool lengths and need less intervention from the person who is flying it.

Not so new

While it’s become an increasingly popular alternative to more traditional forms of photography, Kite Aerial Photography (KAP) actually dates back to the late 19th and early 20th centuries. A camera enabled to operate either remotely or automatically was rigged to a kite whose machinery ranged anywhere from extremely simple to more complex.

According to the website of Charles Benton, a professor of architecture at the University of California, Berkeley, this form of photography was used to provide new perspectives for how people visualized the world from both a practical and aesthetic point of view.

KAP has been used for everything from military reconnaissance and disaster assessment to scientific surveys. George Lawrence, an early pioneer of aerial photography, is the man responsible for taking the iconic “San Francisco in ruins” photograph using a series of kites and wires after the earthquake destroyed a large part of the city in 1906.

Following World War II, aeronautical engineering was applied to kites, parachutes, balloons, hang gliders, and other flying devices.

For those interested in learning more, Mr. Benton, a self-proclaimed kite photography enthusiast, runs a Kite Aerial Photography website and discussion forum that is dedicated to all things KAP.

Solving Waukegan’s sand problem anything but quick

Posted on:

Chicago Tribune: June 21, 2013

by Jennifer Delgado

Superstorm Sandy dumped 60,000 cubic yards of sand into the mouth of Waukegan Harbor last fall, clogging the entrance.

Nearby, beaches have grown thin, in part because all the sand is getting trapped in Waukegan.

The solution to both problems seemed simple: Take the sand from the harbor and put it on the beaches.

That, however, is proving to be more difficult than anyone expected.

Despite efforts by at least two towns to acquire the excess sand, the cost of state-mandated environmental testing is preventing the move, Waukegan officials said. So the sand remains, keeping the harbor shallow and disrupting commercial boat traffic.

“There’s nothing much we can do about it right now,” said Jon Shabica, vice president of Shabica & Associates, a consulting firm working with Waukegan. “The problem with those sets of tests is those municipalities don’t have the money.”

Shabica said that before sand could be taken out of Lake Michigan and moved to nearby beaches, he was told by the Illinois Environmental Protection Agency that it would need to be tested for asbestos fibers, a hazard that has plagued the harbor in the past. The estimated cost of the testing is $17,000, Shabica said.

The state EPA would not comment on whether it is requiring testing of the sand. Officials in sand-starved Lake Bluff think the testing is unnecessary — the U.S. Army Corps of Engineers has conducted annual testing on Waukegan Harbor and has found no asbestos in at least 10 years.

The Corps of Engineers dredges the harbor’s entrance annually, but is permitted to move the sand only to nearby Zion or to a disposal site in the lake. Adding other towns to the permit could take up to a year, said Tim Knoll, operations project manager for the corps’ Chicago district.

“We thought it was going to be a fairly simple process,” said Ron Salski, executive director of the Lake Bluff Park District, which had hoped to get some of the sand for its beaches. “And then when we heard back, it was going to be more complicated and less cost-effective. It wasn’t worth doing.”

Typically, sand along western Lake Michigan migrates from north to south, a littoral pattern that begins along the beaches of Wisconsin and ends at the Indiana Dunes. But much of the sand gets trapped by the walls and structures of Waukegan Harbor, where the nearby beach has grown over the years, according to the Illinois Department of Natural Resources.

The harbor and the nearby Naval Station Great Lakes often block sand from reaching beaches south of the barriers. Public beaches immediately south of Waukegan in North Chicago and Lake Bluff are eroding as a result, local park district officials said.

The Corps of Engineers dredges the approach channel to the harbor annually, moving about 75,000 cubic yards of sand. When superstorm Sandy hit the Chicago area in October, the tempest created 25-foot waves in Lake Michigan that carried nearly a year’s worth of sand accumulation into the approach channel of Waukegan Harbor. The sand pileup halted commercial shipping, already affected by low lake levels.

Waukegan hired Shabica’s firm to monitor the issue and figure out a solution, and it suggested giving away the sand. Waukegan officials liked the idea because it would solve sand problems in the region, said Noelle Kischer-Lepper, the city’s director of policy and projects.

“It seems silly for us to take our excess sand and put it in a landfill somewhere when there’s another beach on the same lake that needs exactly what we have,” she said. “If it comes out of the same body of water, why not move it a few miles down the road?”

Asbestos can scar the lungs and lead to diseases such as cancer, and nearby Illinois Beach State Park in Zion has had problems with asbestos in the past. Spreading sand with asbestos to other communities would be problematic. A state EPA spokesman said the agency met with Waukegan officials about the sand, but he didn’t have enough information to comment on the specifics of those discussions or any asbestos testing.

“It doesn’t financially make sense to pay for what might be a $17,000 test to move what might be $10,000 worth of sand,” said Shabica, whose firm is also working with other lakefront communities on shore protection and coastal restoration.

The harbor is known for its pollution, but Waukegan officials are trying to remove the stigma and the chemicals in the water.

According to the federal EPA, employees at a now-shuttered insulation manufacturing plant began dumping asbestos and other residue into a disposal area that led to Lake Michigan in 1922. Polychlorinated biphenyls were found in Waukegan’s inner harbor in 1976, though the area is being cleaned and is scheduled to be free of contamination by 2014.

Lake Bluff officials said they waited as long as possible in hopes of using Waukegan’s sand. With no resolution in sight, the Lake Bluff Park District last month ordered 528 tons of sand from a quarry, costing $8,000.

The last-minute move delayed opening day on the beaches this month as crews packed the sand onto the ground. An end-of-the-school-year beach party — a 15-year tradition — had to be canceled, Salski said.

In North Chicago, park officials are still hoping the sand comes through. Beachgoers have steered clear of the underdeveloped, eroded beach and its rocky shoreline for 20 years, a problem that Kevin Holley wants to fix.

Holley, executive director of the Foss Park District in North Chicago, said he and others are still hammering out the final plans to rebuild North Chicago’s beach, a project that could begin by the end of this year. The area needs about 4,000 tons of sand to extend the shoreline, he said.

“If we get the sand for free, it’s a huge cost savings for us,” Holley said. “If we have to pay for that much sand, that’s dollars you have to add back into the project.”

The Corps of Engineers’ next dredging in the mouth of Waukegan Harbor is set for mid-July, when the sand will be taken to a disposal area in the lake south of the harbor or north to Illinois Beach State Park, Knoll said.

Knoll said the agency can’t take the sand to Lake Bluff or North Chicago because those towns are not listed in the dredging permit. But the beach in Zion was included at the state’s request, he said.

“We have agreements with the state on where we can” put the sand, he said. “To go anywhere else we would need a brand-new permit with the state, and these permits take about a year.”

On a recent day, Lars Adams spent the afternoon with his three children in the Waukegan Harbor Dunes.

The 26-year-old Waukegan resident said he visits the beach with his kids about once a month during the summer and is eager to see development in the harbor. To him, it starts with cleaning out the sand.

“It’s a really nice place to go and hang out, but the area around is old, empty factories,” he said. “If Waukegan can fix the sand problem and develop (the harbor) the way they want to, I think it can definitely be better.”

Winnetka Park District keeping tabs on beach users

Posted on:

Chicago Tribune: June 11, 2013

by Gregory Trotter

A change in how the Winnetka Park District keeps tabs on the use of its beaches is raising some eyebrows, but officials say it’s for business and safety reasons.

This summer, any Winnetka resident or non-resident wanting to lounge or otherwise recreate on one of the village’s five beaches will need to have their photo taken first. Aspiring beachgoers may also provide their own picture for the park district. A small plastic key fob will be issued and then scanned at the beach by staff. Upon scanning, beach staff can check the photo entered into the park’s system and verify the person’s permitted use.

It may sound complicated, but the new system is intended to simplify and enhance the park district’s ability to manage beach use and track people in case of emergencies, said Terry Schwartz, executive director of the Winnetka Park District. No longer can a summer beach pass be shared among friends, reducing the park district’s revenue, he said. The beaches will be run like a business.

“People do pass around passes,” Schwartz said. “That’s been part of the frustration, but that game is over.”

At Thursday night’s Winnetka Park Board meeting, the rationale for the new system will be discussed. The park district office is also extending its hours this Saturday until 5 p.m. to allow people to more time to have their photos taken, he said.

Winnetka beachgoers have long paid for season passes, but previously those passes did not require photos or digital scanning. Season pass-holders will see a modest increase this summer in cost, said John Muno, Winnetka’s superintendent of recreation. An individual resident will pay an extra $5, bringing the total to $55; non-residents will pay an extra $10, and $90 total. But those increases are not associated with the new system, Muno said.

Not everyone is thrilled about the change. When Mary Garrison’s husband went to pick up their summer passes, he returned with inconvenient news: She would need to go in and have her photo taken.

“I was definitely surpised. That was my first reaction,” said Garrison, who served on the Winnetka Park Board for 17 years, most recently in 2007.

After giving it a little more thought, her misgivings grew.

“If you want to sneak onto a beach, you’re going to find a way,” she said. “Who you’re really going to affect with this system is your citizens.”

People pay a lot of money to live in Winnetka, Garrison said, and the beaches are one reason why. The park district should make it easy for people to access them, she said. In particular, young working families may have difficulties making it into the park district office to have their photos taken.

Schwartz acknowledged there have been some growing pains, but pointed to the district allowing people to use their own photos, and the extended hours on Saturday to get photos taken, as efforts to make the change more convenient.

“Whenever there’s change, people rebut,” Schwartz said. “I don’t get too panicky about it.”

The photos are only required once every five years, he said. In addition to helping the park district manage beach use, they’re also useful to have on file in case of emergency. If a child goes missing, for example, the park district will be able to determine exactly when and where they were last at one of the beaches.

Community swimming pools often use similar ID systems, Schwartz said.

“Why wouldn’t we treat an even more dangerous environment with the same diligence that people treat swimming pools?” he said.

The park district will also be collecting data on beach use to assist in the crafting of a new lakefront master plan in the coming years, Schwartz said.

The new ID system represented a $6,500 increase to the budget for the new equipment: six new iPhones with built in scanners, said Muno. So far, a total of 2,000 people are covered with the new passes.

John Thomas, who serves on the park board, said the change was approved as a budget item in February with little discussion.

“My view is that the system is in place, and if it does what the staff thinks it will do, that’s a good thing,” Thomas said. “If not, we’ll make adjustments next year.”

On a recent foggy late morning at Lloyd Park Beach, Jim Karabas idled in the parking lot, waiting to pick up his kid from sailing camp. He said his family visits the beach almost every weekend in the summer.

“It will be more difficult to get a pass, but if it’s good to keep up with people better on the beaches, maybe that’s a good thing,” Karabas said. “Taking advantage of technology, I guess.”

Nick Robbins, the park district’s manager of the Lloyd Park boat launch, said the new system has made life much easier for the beach staff. Instead of having a season beach pass and a boat launch pass, for example, there’s just one pass.

“I think it’s all been pretty much positive so far,” he said.

Tristan Jenista sat in his car, looking out at the waves on the lake. A Wilmette resident and stand-up paddle boarder, Jenista said he visits Lloyd Park almost every day in the summer.

“If Big Brother’s watching me, I don’t have a problem with it,” Jenista said.

Lower lake levels plague harbors but benefit beachgoers

Usually by this time of the year, Mary Avellone’s light blue sailboat is floating beside a couple dozen other vessels at the Jackson Park Outer Harbor on the city’s South Side.

But Avellone sees only a handful of boats in the water these days. Low lake levels combined with a pileup of sand forced a few of her neighbors to dock at other marinas. Others are waiting out the problems and haven’t dropped their boats in at all, she said.

“We’re very upset about it,” said Avellone, 65, a boater since she was 7 years old. “People do spend quite a bit of money to have the pleasure of having their boat there.”

With boating and beach season kicking into gear this holiday weekend, harbors and beaches along Lake Michigan are still reeling from the effects of last year’s drought, which sent lake levels dipping to a historical low in January.

Recent spring storms lifted levels but also pushed more sand near the water’s edge.

The combination of drifting sand and receding water has created conditions good and bad along the shoreline, from expanded beaches with more room for sunbathing to low water depths that pose dangers for boats.

“Hopefully the situation will get better, but who knows,” said Scott Baumgartner, commodore of the Chicago Yachting Association, who can’t remember the water standing so low. “The whole thing hinges on our hope that the water levels don’t continue to drop.”

Water levels in Lakes Michigan and Huron have been below average for 14 years, a result of milder winters, drier springs and a spike in evaporation.

Even though levels are slowly climbing, the lake is 22 inches below the long-term average, according to the Army Corps of Engineers.

That has helped the sandy beaches in Wilmette expand by roughly 5 feet over the last several years.

To manage the larger beach, the park district has tripled the size of its patrol staff to monitor the growing southern end, making sure people follow policies that prohibit tents, alcohol and swimming in areas without a lifeguard, said Kathy Bingham, the district’s recreation superintendent.

“It’s just the nature of having a beautiful park and a lakefront. … It’s going to attract a lot of people,” Bingham said. “That’s what we deal with in the summer.”

Nearby beaches in Winnetka and Evanston have also grown since the 1990s as sand from farther north lands on the lakefront.

Winnetka will test water levels for the next few weeks to gauge any effects on recreation. Heavy April rains boosted the water level there by nearly 2 feet in less than a month, making it possible to open a popular boat launch in time for Memorial Day festivities.

Beaches have also grown along the Indiana Dunes, where officials estimate 2 feet of sand have been added to the western end of the popular destination over the past year.

Waukegan has seen so much sand accumulate on its beaches that it wants to give some to sand-starved beaches in Lake Bluff and North Chicago.

But paying $17,000 for a state-mandated environmental test of the sand may be cost-prohibitive, said Jon Shabica of Shabica & Associates, which is working with six lakefront communities on shore protection and coastal restoration.

Meanwhile in Chicago, retreating water is affecting boaters and beachgoers.

While beaches have swelled over the years, a dozen or so boats have moved because of shallow water to deeper spots like 31st Street Harbor, which opened last spring. A few boat launch ramps and slips are unusable and being renovated because of low lake levels.

Southern marinas along the Chicago lakefront have been affected the most by the receding water. Some larger boats trying to get into harbors at 59th Street and Jackson Park Outer struggle to make it through.

To remove the sand and natural silt at Jackson Park Outer, workers dredged the area for two weeks this month, an almost annual ritual, said Scott Stevenson, executive vice president of Westrec Marinas, the company that manages the Chicago Park District’s 10 harbors.

Low lake levels exacerbate the harbor’s existing issues with sand that comes from the north and south and accumulates in the entrance.

“We’re exploring options for long-term solutions, like building a breakwater out into the lake that would prevent sand from coming into the harbor and make it unnecessary to dredge every year,” Stevenson said.

Typically, lake levels follow a seasonal pattern, rising in the spring months from melted snow and rain until they reach a peak in middle to late summer and then begin falling as water evaporates.

But how much the lake rises and falls changes from year to year, said Keith Kompoltowicz, chief of watershed hydrology for the Army Corps of Engineers’ Detroit District.

A shift to dry conditions in the late 1990s produced a 1999-2000 winter that yielded very little snow in the Great Lakes basin, leaving a small amount of water to run off into the lakes, he said.

The levels haven’t rebounded. Adding to the problem was an abnormally warm winter at the end of 2011 across the Great Lakes region followed by a dry spring last year. Then a hot, arid summer led to above-average evaporation that continued into last fall.

This past January, Lake Michigan levels reached 576.02 feet, the lowest recorded for that month since the agency started keeping records in 1918. The level has risen 13 inches so far and is projected to climb up by 5 more inches by early August.

“We are in a different regime of weather because of climate,” said Henry Henderson, director of the Natural Resources Defense Council’s Midwest program. “There are a range of things being affected by this.”

Lower lake levels mean that the potential for dangers and damage to boats lurks in unseen places.

Concrete blocks and other large objects sitting at the bottom of the lake are closer to the bottoms of boats. And vessels navigating near walls along the shore are finding the area doesn’t have enough depth.

“The problem hasn’t resolved itself by any stretch,” said the Chicago Yachting Association’s Baumgartner. “Yes, indeed, there has been a very slight rise in the levels — but it’s not enough to remedy the problem in full. It’s going to take several years of normal weather to get us back to where we should be.”

For Avellone, who believes maintenance is to blame for her harbor’s problems, the lake levels and silt are more than just an irritation. They may be reason for her frustrated neighbors with larger boats to sail to other marinas.

“Harbors are like neighborhoods,” she said. “It really disturbs the sense of community in the harbors that have been neglected for so many years while they spent all this money building 31st (Street Harbor.)”

Lloyd Park boat ramp will open for use this summer

The Lloyd Park boat ramp will be open for use this summer after the lake level recently rebounded from a historic low in January.

Months of hand-wringing and study gave way to relief Thursday night as the Winnetka Park Board made the decision. The unlikely hero in this scenario was the April 18 storm that flooded much of the Chicago area. Since that storm, the lake level rose nearly a foot, creating larger waves to drag sand away from shore. The net effect is that there’s four feet of water at the base of the Lloyd Park boat ramp, said Jon Shabica, a coastline engineer hired as a consultant to study the issue.

Launching from the popular North Shore ramp appeared unlikely in January, when the water was at an all-time recorded low and five feet lower than it was in 1997, Shabica said then, using data from the U.S. Army Corps of Engineers. The problem was compounded by large amounts of sand accumulated near the ramp.

But last month’s storm changed everything.

“To have this change in two and a half weeks is just amazing,” said Shabica, whose company, Shabica & Associates Inc., has been assisting several North Shore municipalities.”It’s a nice thing that conditions have improved, but that doesn’t mean they’re guaranteed.”

The ramp will open May 25, just two days later than usual, said John Muno, Winnetka’s superintendent of recreation. Registration for launching permits will open on Monday with priority given to Winnetka residents, Muno said.

Dredging will occur soon to make it possible. Winnetka Park District usually spends about $25,000 to $30,000 on dredging. Shabica’s recommendation for dredging will end up falling within that typical amount, park officials said.

Previously, park board members had discussed dredging at Tower Beach, to the north, to create a reservoir for sand that drifts south to Lloyd Park. But on Thursday, they said that would be part of a longer-range plan that would require more permits and discussion with the village.

An increase in launching fees had some boaters riled up at the last Park Board meeting. For non-residents, unlimited summer use of the ramp will increase from $650 to $1,000 – an increase of almost 54 percent. Winnetka residents would only see an increase of $75, from $325 to $400.

“Whatever it is, it’s worth it,” Frank McGuinn, a boater, said at Thursday night’s park board meeting.

Like many other North Shore boaters, McGuinn has been following the Lloyd Park boat ramp discussion closely. A Northbrook resident, McGuinn said he would have to go up to Waukegan to launch his WaveRunner if the Lloyd Park facility had been closed.

McGuinn said he went to Lloyd Park a week after the April 18 storm and water level actually looked worse than before. He was therefore expecting bad news at Thursday’s meeting. Instead, he left beaming.

“This is my whole summer,” McGuinn said.

Winnetka Park Board to decide May 9 whether to open Lloyd Park boat ramp

The Winnetka Park Board is expected to make a decision May 9 about whether the Lloyd Park boat ramp will open this season.

Low water levels and sand accumulation have park directors considering closing the ramp to boaters this summer. The April 18 storm that left much of Chicagoland flooded presented a sliver of hope for Lloyd Park boaters.

The lake water rose 11 inches after the storm, according to Jon Shabica, the coastal engineer working with Winnetka and other municipalities along the North Shore.

It may not be enough. There’s a bed of pebbly sand at the base of ramp, instead of the required three feet of water.

The park board will decide whether to open the ramp to all boaters, non-motorized boaters or none. At the heart of the issue is whether to invest in dredging that may only provide temporary relief to sand accumulation, said Terry Schwartz, executive director of the Winnetka Park District.

“The board has to make a decision about what kind of risk to take relevant to a do over,” Schwartz said, speaking to the possibility that any dredging effort could be undermined by the wrong kind of storm.

The April 18 storm also helped out Lloyd Park by moving some sand away from the shore. But there’s still a significant accumulation outside of the ramp and a large sandbar just to the south, Schwartz said. Sand accumulation compounds the issue of the low water levels.

“The real problem is what’s below the water,” Schwartz said.

The park district, working with Shabica & Associates, would need to take a three-pronged approach to address the sand issue, he said. First, the district would have to create a “pothole” at Tower Beach for sand to accumulate. Currently, sand migrates south from a small strip of privately-owned land between the water treatment plant and Tower Beach, he said, and accumulates at Lloyd Park.

Early conversations with the private land owners are underway, Schwartz said. To build the pothole, the park district would also need village approval, as a portion of Tower Beach is owned by the village.

Secondly, the park district would need to level the sand accumulated at Lloyd Park, and then, finally, dredge out into the lake, effectively creating a channel for boats. Schwartz said he didn’t yet know how far out in the lake it would need to dredge — or how much the combined measures would cost — but that more information would be available at the May 9 meeting.

The park district typically dredges once a year, in early April, to the tune of about $25,000 to $30,000, he said. Beyond the cost-benefit analysis, the park board will also have to consider the safety of boaters, as well as the many kayakers and stand-up paddle boarders who also use Lloyd Park, he said.

As for the water level, Schwartz said it’s unlikely to rise any more from now until the end of July.

A group of fishermen at the recent park board meeting, hoping for good news, left early and disappointed. Many of them launch from Evanston, which is also dealing with low water and sand accumulation issues.

They were also disgruntled by a rise in launch fees. If there is power boating in Winnetka this year, non-residents can expect to see a fee hike of almost 54 percent — from $650 to $1,000 — for unlimited use of the launch. Residents would see an increase of $75, from $325 to $400.

The increase is meant to stay competitive with other nearby boat launch facilities and to offset the operating costs for the park district, Schwartz said.

Wally Ross, 81, of Skokie, said he’s been launching from Lloyd Park for 10 years. His friend, Mike Gelfand, of Chicago, typically launches from Evanston. Both men were disappointed at the prospect of rising fees and low water levels, but said they’d find a way to keep fishing.

“If we’re breathing, we’re fishing,” Gelfand said, and they laughed.

 

Winnetka Park District Lakefront Update

Winnetka Park District: April 29, 2013

Since January, 2013, the Park District staff and consulting group of Shabica & Associates have been closely monitoring Lloyd beach and boat launch, due to unprecedented and historic low Lake Michigan water levels.

There is a pending recommendation to limit the launch activity to non-motorized vessels for the 2013 season due to insufficient water depths not enabling safe ingress/egress of the pier/launch area.
On April 25, 2013 a Park Board Committee of the Whole was conducted at 4:30 pm, followed by a regular meeting of the Park Board. The main topic of the committee meeting was discussing the ongoing challenges facing the lakefront, and its potential affect on the operation of Lloyd Boat Launch for this upcoming summer. The Park District, consultant, Mr. Jon Shabica provided an information report update regarding the issue.
WPD 4/25/2013 Lakefront Update
Due to the recent storms and heavy rains raising Lake Michigan water levels an estimated 11 inches, as well as shifting sand patterns in and around the launch area, there has been some improvement in water depth and sand conditions. These improved conditions have resulted in a recommendation for Shabica & Associates to continue to monitor the launch area and provide an updated recommendation at the May 9, 2013 Park Board Committee meeting at 5:30 pm.

Harbor Association nabs 39-year win

Posted on:

Wilmette Life, A Chicago Sun-Times Publication: April 25, 2013

by Kathy Routliffe

Relieved Wilmette Harbor Association members hugged outside the Metropolitan Water Reclamation District’s boardroom Thursday, after MWRD commissioners gave the group the 39-year harbor management lease it sought.

The unanimous vote reverses an April 4 rejection of the WHA’s $68,501 bid, which went against MWRD staff recommendations and threatened to leave the harbor closed after April 30 and unattended this summer.

“It’s a relief,” WHA board member Kristin Keenan said. “I’m stunned, but happy.”

WHA Harbormaster Sabine Herber said her next step was to call a contractor to dredge the tiny harbor, clearing it of silt and making it usable for both the MWRD’s pumping station and the almost 300 boaters who will use it this summer.

“The dredger has been very patiently waiting to hear from us, so that’s my first phone call,” Herber said.

She had already been up for hours, checking the harbor early Thursday after torrential flooding forced the MWRD to open its floodgates there.

“This has been a long and difficult process, and we’re very pleased with the outcome,” she said after the vote. She praised the support of Wilmette residents who lobbied the MWRD to rethink its initial rejection.

“I was copied on a lot of messages (to the MWRD) from residents, not members of the association – people I didn’t know, who said they wanted the WHA to have the lease,” she said. “It’s very heartening that the community likes what we’re doing.”

Some Wilmette residents attended the MWRD meeting, as did Wilmette Park District Commissioner Gary Benz and newly elected Park Board member Bryan Abbott.

Abbot asked the MWRD to consider taking part in a task force that would look at the best ways to make community use of Wilmette Harbor. Abbott said that could include neighboring residents and institutions, including the village and the park district – which last year decided against trying for a lease itself, after more than a year of informal discussions with the WHA.

MWRD Commissioners Barbara McGowan and Maryana Spyropoulos were the only two to speak before the vote. Both said they would have preferred to offer the WHA a shorter lease, but were willing to approve the 39-year agreement.

McGowan, whose procurement committee first recommended the WHA, voted to reject it April 4. She said Thursday she changed her mind after meeting with MWRD Executive Director David St. Pierre, “and hearing his reasons for not wanting to do a short lease.”

The association has handled the harbor for the MWRD for 75 years, and representatives throughout the bid process had emphasized their history of efficient management and good relations with its neighbors. The WHA also noted that opposing bidders had no management experience.

Opposition included a branch of Wisconsin-based CenterPointe Yacht Services LLC, and Wilmette Harbor Management Inc., at least two of whose founders live in neighboring Winnetka. Both had proffered $70,000 offers, but MWRD staff called both bids financially non-responsive.

WHM Inc. President Fritz Duda angrily accused MWRD staff of “protecting” the WHA throughout the bid process.

Doing so cost Wilmette residents and taxpayers money and essentially left the harbor in the hands of a private yacht club, he said. He did not clarify whether he meant the WHA or the separate Sheridan Shores Yacht Club, which operates out of the harbor.

WHM directors had promised to make the harbor more accessible to the public, and planned to try to expand services.

After the vote, Duda repeated charges he made April 17 and again before the vote: MWRD staff never told WHM Inc. why its bid was rejected despite repeated pleas for information, he said.

Duda, of Winnetka, told commissioners Thursday they should accept one of the higher bids, or rebid the lease entirely and give the WHA a one-year lease while the process went on.

WHM directors would have to talk before deciding their next move, he said

“We’re not going to comment on that.”
