Urban Habitat Projects

Floating Islands

MIlwaukee, WI
The Milwaukee River lacks bank vegetation and natural habitat for macro-invertebrates and many fish species because it is lined with steel sheet piling or concrete. In order to improve the spawning and habitat conditions, floating islands were implemented in some areas of the river. The floating islands are made of both synthetic and natural material, benefiting plant growth. Then, algae and biofilms quickly colonize the structures, creating food for zooplankton, and then small fish. The floating islands are designed to provide heavy vegetation providing food, oxygen, and shelter to the fish that are heading upstream to spawn or just passing through. Even more, these structures mimic wetlands, which 80% of native Great Lakes fish species depend on.

Hanging Underwater Baskets

MIlwaukee, WI
The hardened shorelines of the Menomonee, Kinnickinnic, and Milwaukee Rivers make it extremely difficult for plants to grow along the bank. Moreover, because of heavy ship traffic in these urban waterways, many of the river bottoms were dredged, leaving both the shoreline and bottom regions an aquatic desert. Therefore, Groundwork Milwaukee has introduced several floating islands, as well as over 200 habitat underwater baskets in each of the 3 rivers leading to Lake Michigan. These baskets are designed to house plants in-between the corrugations of the sheet piling, introducing food and shelter for fish passing through.

Fish Hotel

Chicago, IL
The Chicago River habitat also suffers from its urban location, usage, and lack of natural vegetation on its riverbank. Thus, the Chicago River walk introduced Fish Hotels. These are fish habitats that provide a portable or permanent habitat that can support algae and macro-invertebrates. Fish hotels provide food and shelter for fish traveling through the river.

HABITAT FOR HARD PLACES

Cleveland, OH
The Cuyahoga River flows through a heavy industrial area of Cleveland that handles large ships and barges. Like other Great Lakes shipping regions, the steel and concrete holding the riverbanks together and the dredged river bottoms lack proper fish and wildlife habitat. The Cuyahoga River is the passageway for fish to enter Lake Erie and without appropriate habitat; spawning and fisheries are negatively impacted. Therefore, in 2015 and 2016, gated structures were put in place along the river wall that provides food and shelter from predators.

FISH HABITAT ENHANCEMENT DEVICES

New York, NY
To improve the shoreline of the Hudson River, FishHEDs were introduced. The fish habitat enhancement devises are designed with steel and mounted on the harbor wall with brackets. The structures hang in the water and provide alternative spaces for macro-invertebrates and fish to congregate.

BIOHUTS

Baltimore, MD
Baltimore’s Inner Harbor has lacked refuge vegetation and habitat for fish passing through. Therefore, Biohuts were installed on the bulkheads of the harbor. A Biohut consists of a double layer cage. The innermost portion is filled with oyster shells. These shells attract microorganisms, which quickly colonize the area. The oyster shells contain juvenile oysters, which can grow and filter out algae from the water. Then, barnacles and mussels can attach to the shells and structures, further filtering the water. The outermost cage offers a predator-free zone for any juvenile fish.

LOWER DON LANDS

Toronto, Canada
The Lower Don Lands consist of 308 acres of Toronto waterfront that has been neglected over the years, as it is part of a shipping channel. The vision for this space includes merging the urban and natural environments to meet the cities’ sustainable and community goals.

THE PORT LANDS FLOOD PROJECTION PROJECT

Toronto, Canada
Downtown Toronto’s southeastern region could be easily overwhelmed by floodwaters in an extreme weather event. In fact, 290 hectares are at risk of flooding from the Don River. Therefore, it is proposed that the Don River be reconnected to Lake Ontario by creating a river mouth. This project would include over 1,000 m of new river channel, 13 hectares of new wetland, 5 hectares of terrestrial habitat within the constructed valley, and the enhancement of 14 hectares of aquatic habitat. The new river mouth will remove the flood risk to 240 hectares of land.

CORKTOWN COMMON

Toronto, Canada
Toronto has several parks that will help connect the public with the environment. The Corktown Common Park will offer a diverse range of experiences and both views of the city and natural habitat. The park contains playgrounds, a splash pad, and an athletic field. Moreover, the park is home to over 700 trees and thousands of shrubs, groundcovers and aquatic plants. The ecological richness of the park will aid in plant and animal biodiversity. Additionally, the marsh will provide both an onsite storm water management system and a habitat for birds, amphibians, and insects.
