Ingalls MallTriton SWS Creates Win-Win for University of Michigan Project
The University of Michigan needed to upgrade its historic Ingalls Mall area of campus to modernize existing electrical and pedestrian lighting infrastructure, improve fire safety apparatus and expand its stormwater management capabilities.
Because the Ingalls Mall area is a major pedestrian throughway for students, faculty and visitors, construction activities had to be strictly confined to a small footprint – and completed as effi
Further, the University needed to retain more of the Mall area’s stormwater onsite, with less outflow to the City of Ann Arbor’s storm sewer system. Because of the limited area available, the plan required a robust, underground system with proven storage capacity.
The existing system had storm receptacles serving as pre-treatment units for incoming water, so the new design had to incorporate sediment control and pre- treatment features along with improved retention.
SJ Roberts Homes ProjectFollowing an evaluation from Severn Trent Water’s New Products CoP Group Waste team, Triton Stormwater Solutions’ Stormwater Management System has been approved for use within Severn Trent on both AMP 6 Capital and Developer Sites.
SJ Roberts Homes latest development of 172 houses at Sweetlake Meadows in Shrewsbury required a stormwater management system to provide in excess of 1043m3 water storage. A fundamental requirement for the system was that it had to be adopted by Severn Trent Water.
Crane Bennett ProjectWhen developers sought to create a new apartment development at the site of a longtime Minneapolis lumber yard, they knew that the supporting infrastructure would be a challenge. Spanning nearly a city block, the complex needed a state-of-the-art underground stormwater management system to support the construction, within the constraints of limited space. Additionally, the construction was going to take place in a busy urban area – closing streets or otherwise impeding daily traffic would be difficult and expensive.
To meet the requirements of the project, 14,131 cubic feet of stormwater storage was needed. Because of the site's constraints, project engineers chose to place two separate systems on opposite sides of the building.
Duluth Airport ProjectThe desire to upgrade facilities and expand the travel options of people in the greater Duluth region led airport planners and the state of Minnesota to build a new terminal at Duluth International Airport. The new construction and associated impervious surface will cover roughly 13 acres, creating the need for a robust and easily maintained stormwater management system.
The Duluth area has several challenging aspects for developers – rocky landscapes and subsoil, extreme weather and an awe-inspiring natural environment that needs to be protected. Additionally, because of the problems associated with wildlife being attracted to the standing waters of retention ponds — and the risks this poses near airports – developers were required to…
Unversity of St. ThomasThe University of St. Thomas needed a cutting-edge stormwater management system to support construction of a 180,000-square-foot athletic facility. The Anderson Athletic and Recreation Complex – which houses an aquatic center, 2,000-seat arena, a field house with 200m track, fitness facilities, locker rooms, and department offices for Athletics and Health and Human Performance – will become a showcase center for the St. Paul, Minn., school.
Because of the layout of the building, stormwater management needed to be done at two separate locations. This required coordination of equipment and manpower – but the Triton SWS' lightweight chambers, which require no heavy machinery for placement, helped ease this burden.
Additionally, initial so…
Lowes Home ImprovementLowe's Home Improvement Centers needed strong, state- of-the-art underground stormwater management for its new store in Silverthorne, Colorado. The 11.5-acre site featured sloping terrain and required a small stormwater storage footprint with proven protection of water quality.
The Triton SWS chambers met the project engineers' needs on every level.
The layout of the project site meant that the underground chambers would need to be strong enough to withstand 21 feet of backfill weight. Additionally, the Siverthorne project site was subject to the stringent water-quality standards of the greater-Denver region.
Toronto Retail CenterEngineers from Terrafix Geosynthetics needed a high-quality, high-strength, high-volume underground stormwater management system to support construction of a 600,000 square-foot retail center in Toronto.
The project demanded a small storm- water footprint with enough capacity to store the runoff from the shopping area and parking lots. Additionally, a system flexible enough to work with the existing site infrastructure, including a storage tank and large diameter underground pipe, was needed.
An added challenge was posed by the fact that the system would need to be strong enough to be buried 24 feet below the surface
Metro Transit of Minneapolis/St. PaulMetro Transit of Minneapolis/St. Paul needed to expand its Hiawatha Line operations and maintenance facility to meet the growing need for light rail travel in the Twin Cities. This required additional stormwater storage capacity – a big challenge given the constraints of the site; the numerous poles required to power the trains dotted the entire area, putting usable space at a premium, and demanding a flexible design.
Triton Stormwater Solutions innovative underground chambers, boasting large storage capacity and unrivaled strength – which allows them to be stacked to increase storage volume while saving space – meant that the project could meet the stringent requirements without disrupting the existing site infrastructure.
Scarsdale Veterinary HospitalThe new state-of-the-art Scarsdale Veterinary Hospital, located in the Pride Park business hub in Derby, UK, needed to upgrade its stormwater management capabilities to meet Britain’s new standards for control of 30-year rainfall event run-off.
As the law requires stormwater to be contained on site, project engineers wanted to be able to utilize underground storage techniques to save limited surface lands for needed uses, such as the parking lot for hospital patrons.
Significant storage capacity was needed, as the area contained nearly 30,000 square feet (2,787 square meters) of rooftops, as well as the hospital’s half acre (2,023 square meters) parking lot.
Because the system was to be placed beneath the parking lot, long…
St. Cloud, MN Civic Center ExpansionThe Situation
When the city of St. Cloud, Minnesota, needed a comprehensive underground stormwater management solution to support the expansion of its Civic Center, project engineers looked for a system able to accommodate the large volume of water associated with the new development that could also fit the restrictive footprint dictated by the site – while meeting the state's stringent B-3 guidelines for stormwater management.
It was a tall order – considering that more than 3 acres of impervious surface would drain into a retention area of just 36' x 140'.
Fortunately, there is one system that can "stack" up against such a task.
With its unique combination of storage volume and strength, Triton Stormwater Soluti…
Penn-DOT in DuboisWhen the Pennsylvania Department of Transportation needed a stormwater management solution to support changes at a busy hospital intersection in Dubois, they initially spec'd a Triton competitor's product in the bid proposal. But, when the contractor suggested the Triton system as a time- and cost- saving alternative, Penn-DOT opened its ears and eyes.
Recognizing the Triton system's advantages in recreating pre-development hydrology, ease of maintenance, strength and storage capacity, Penn-DOT approved the Triton product, which also qualified the project for LEED credits.
The Dubois project called for storage of stormwater from the streets at the intersection, as well as the hospital's parking lot. It also needed to be robust enough t…
University of Hawaii Chooses Triton for New Oceanography CenterThe Situation
The University of Hawaii outside Honolulu was building a new 30,000 square-foot addition to its existing Biomedical Science Building to house the Center for Microbial Oceanography: Research & Education (C-MORE).
The building was designed with sustainable design principles and energy-efficient strategies, and is currently targeting LEED Gold certification. Project manager Kimberly Polkinhorn, an associate with Group 70 International, noted that the Triton system was selected to minimize stormwater flow to the storm drainage system, and to allow the water to percolate back into the ground and recharge the water table.
Since the project site is in a rainy part of the island, minimizing run-off entering the overtaxed sto…
Luther Brookdale Chevrolet DealershipThe Situation
Luther Brookdale Chevrolet in Brooklyn Center, Minnesota was an older dealership in need of a facelift. “An entire renovation was taking place to improve both the inside and out,” explains
Lance Hoff, water resource engineer, Royal Environmental, a division of Royal Enterprises. New storm water chambers were necessary to meet regulatory requirements for the city and watershed district.
“We had to meet the 2 year, 10 year and 100 year storm events for rate control, and watershed requirements required us to use best management practice in infiltration,” explains Nathan Wallerstedt, design engineer, LandForm, who engineered the project. "In order to make our best effort we decided to use a bottomless system to ac…
Starlite Metro Bus TransitThe Situation
The Starlite Metro Transit bus stop in the Brooklyn Park, Minn. commercial retail shopping center was in great need of improvement. The bus stop is located in a small triangular section of a fully developed mall parking lot that was still unpaved and serviced by a storm water pond. Metro Transit wanted to gain more usable space for this small area to serve the busses that pulled in and out all day by replacing the pond with an underground storm water system.
Through its association with Royal Enterprises, a Triton stormwater detention system was selected to meet the unique design challenges of the site.
In addition to fitting an extremely small and triangular shaped area, the Triton system had t…
City of MaplewoodThe Situation
The city of Maplewood, a metropolitan suburb of the Twin Cities in Minnesota, needed to make some improvements on a key roadway called Castle Avenue. There were several issues at hand, according to Steve Kummer, staff engineer, City of Maplewood, who designed and engineered the project.
“First, the pavement was in very poor shape,” he explains. “Second, we are expecting future development in that area that we had to accommodate by widening the road. Lastly, we had to implement some traffic calming measures to increase safety along the roadway, such as adding curb and gutter and adjusting the existing roadway profile so folks slow down when they go around the curve and downhill.”
In addition, the city had to meet a…
Champion Jeep DealershipThe Situation
A few years ago, local businessman Len Nadolski was considering purchasing the vacant Pontiac Buick dealership in Lansing, Mich., an older dealership that had been closed a few years. Nadolski wanted to remodel the existing building and add 10,000 square feet to renovate it into a Chrysler Jeep Dodge dealership. Chrysler was encouraging its dealers to revamp their stores into these “Alpha” dealerships, with all Chrysler brands under one roof. The only problem was that the dealership had a stormwater eaement that went across the neighbor's property.
“While considering the purchase, the neighbor closed off the easement which just about killed the deal,” explains Stan Schafer, owner of Schafer Construction in Bright…
Fast Food Restaurant UpgradeThe Situation
An existing fast food restaurant, located within the fully developed St. Paul, MN city limits, was greatly in need of an update. Not only did the store itself need a facelift, but the property needed to be redeveloped to meet the new watershed requirements that had been put in place since the area was originally developed. Requirements dictated infiltration, filtration and rate control of stormwater to be used on redevelopment projects within its watershed districts.
The site contained an above ground detention holding pond that was not adequate with current standards for water retention. Heavy rains would cause the pond to overflow and flood the local area.
The land itself was more valuable than the pond due to the …
Keyser Shopping ComplexThe Situation
Keyser, West Virginia, a small town outside Cumberland with an estimated population of just 5,515, had nothing in the way of retail besides a Wal-Mart. So when a local entrepreneur decided to build a new $7 million outdoor shopping complex on the outskirts of town, it was a big deal for local residents.
"This was much-needed and very exciting, "explains Kevin Sandridge, of Norco, who served as project manager. "There was nothing here before but a field with mountains on either side." Seven acres of the 15 acre site were partially developed to include two large buildings 91 feet wide by 260 feet and 380 feet long, respectively. Parcels are available to be sold off for future free –standing buildings such as banks, rest…
International PlaceThe Situation
International Place, a six-story office building in Shelton, Connecticut needed additional parking. However, the pond detention configuration in use didn't allow for the parking lot to be expanded.
The project faced the additional challenge of only being able to work from two sides of the building as the other areas extend into a wetland.
Through its association with Environment 21, LLC, a Triton Stormwater Solutions retention system was selected by Connecticut Pre-Cast, the developer's supplier for manhole storm systems. The Environment 21 design and engineer team worked with Connecticut Pre-Cast to develop a design and layout that met the project needs for stormwater hydraulics and site constraint…
Walser Honda DealershipThe Situation
Located south of the Twin Cities in Burnsville, Minnesota, Walser Honda needed to expand their parking lot to maximize the usable area for both retail sales and customer parking. The site did not allow room for traditional storm water storage, but required an underground system to be installed under the entire parking lot site. Triton Stormwater Solutions in Brighton, Michigan was selected as the stormwater system provider.
Triton's proprietary design and patented construction offers larger-capacity, lighter-weight, easier-to-install stormwater chambers that are more than 50 percent stronger than traditional products. Triton stormwater chambers have 46 percent greater capacity per linear foot and withstand 16,000 more…
Green Oak Township, MichiganWhen homeowner Brent Zinn bought his house last December, he had a rude awakening come spring.
"My walk-out basement doors are at the lowest point in the neighborhood," he explains. "When the ground thawed, the water from melting snow and ice basically rolled down the ground and straight into my finished basement. There was a tremendous amount of water coming in."
Built in 1991, the yard was never graded properly. This past winter was particularly harsh with several large snowfalls. "The ground would warm up then freeze again and again creating ice which basically sealed up the ground and prevented water from soaking in," says Zinn.
The previous homeowners had a 55 gallon trashcan filled with rocks buried underground that would collec…
Monterey Bay Idea HouseThe Situation
The Monterey Bay Idea House, the latest in the line of select West Coast homes built by Sunset magazine to showcase new and exciting products, presents a multitude of eco-friendly features in response to the need for energy efficiency, function and sustainability.
Located in an exclusive residential community in the mountains overlooking the ocean, the house was designed working closely with Monterey County to illustrate how green building can be done. “The county wants to encourage going green by expediting permits and offering other incentives,” explains Tom Messenger, who served as project manager. "The Monterey Bay House needed to be at least 70 percent green through environmentally-friendly features such as the u…
