E-M:/ Proposed Development on Lower Detroit River

DETROIT RIVER INFORMATION SHEET
Proposed Trenton/Gibraltar Development Project, Detroit River
Made in Detroit, Inc. is proposing a waterfront development project in
the lower Trenton Channel, Detroit River entitled the Trenton/Gibraltar
Development Project, as it includes a stretch of property which lies in both
the cities of Trenton and Gibraltar. The development project includes a
luxury marina, 20,000-seat outdoor amphitheatre, approximately 350 homes,
health club, golf courses, equestrian stable and riding center, restaurants,
other recreational activities, and parking facilities. Newspaper articles
concerning the development have appeared in the News-Herald (in part) on July
7, 1996; February 2, 1997; and February 16, 1997.
The development site is east of West Jefferson between Van Horn and
Gibraltar Roads and west of West Jefferson between Vreeland and Gibraltar
Roads. The development is primarily centered around the junction of Vreeland
and West Jefferson. The properties are owned by Waste Management, Chrysler
Corporation, and DSC Ltd. (formerly McClouth Steel). The waterfront area is
commonly known as Chrysler Bay (two-part embayment) and Duck Hunter's Island
(sometimes referred to as Humbug Bar or Humbug Island). A considerable
amount of the property has been industrial with a chemical plant, landfills,
and other waste storage areas. The area has been previously fenced/diked in
the vicinity of the Island and there has been some land filling in the
mainland area. No property has been purchased by the developer at this time.
An estimate of the property lines show that the marina, the amphitheatre,
and approximately 50 dwelling units would be located in Trenton. The
remainder of the development appears to lie in Gibraltar; however, the city
or cities that Duck Hunter s Island falls in is unclear. Approximately 50
dwellings with half-acre lots would be built on Duck Hunter s Island,
approximately 250 units with quarter-acre lots on the Gibraltar mainland, in
addition to the 50 units with quarter-acre lots in Trenton. Dwelling unit
costs start at approximately $500,000 and upwards dependent on location. A
culvert bridge would be built from the mainland to the Island as an
entrance/egress. Development cost is projected at approximately $500
million. Considerable construction employment and long-term employment at the
site is projected. Benefits to Trenton and Gibraltar are also projected from
Two of the main obstacles are transportation concerns and environmental
concerns. Transportation concerns center around congestion both from new
local traffic and traffic due to the amphitheatre. These concerms may be
alleviated by widening West Jefferson, Vreeland, and Van Horn Roads, with the
possible intervention of other road planning groups and the widening of West
Road. There is also great potential of traffic congestion at the railway
crossings on Vreeland, Van Horn, and Allen Roads. Bridges over the railways
at these sites could potentially relieve some of this congestion.
A wide range of environmental concerns arise regarding the development
including loss of wetlands, impacts on fish and wildlife, resuspension of
contaminated sediments, and impairment of recreational usage . The area
proposed to be developed adjoins the only remaining classifiable
wetland/aquatic macrophyte area on the Michigan mainland side of the Detroit
River. The development may encroach on this contiguous wetland and will
directly include smaller wetland areas. The development area falls within a
larger area of the lower Detroit River that is planned for preservation and
protection by local environmental groups.
There has been some activity by environmental groups and others will
probably become involved as they become familiar with the development and
issues; these include: Michigan United Conservation Club, Sierra Club, Grosse
Ile Land and Nature Conservancy, Ducks Unlimited, Citizens Environment
Alliance of Southwest Ontario, Downriver Citizens for a Safe Environment, and
Detroit River Remedial Action Council.
Some of the primary environmental issues are:
Should property adjoining the last remaining wetlands on the Michigan
mainland of the Detroit River be developed?
Would any wetlands mitigation efforts provide ecological habitat and function
or enhancement of Detroit River aquatic life, waterfowl, and wildlife,
comparable to the wetlands which are to be developed/lost?
What is the total area of wetland habitat that will be disturbed?
What portion of the wetland will be filled?
Is development of this area consistent with the goals and objectives of the
Detroit River Remedial Action Plan (RAP) for preserving and protecting fish
and wildlife habitat?
Is this area a fish spawning site?
Is this area a fish nursery site?
Is this area a flyway and feeding area for waterfowl?
Are there rare, threatened, and/or endangered plants, aquatic life, or
wildlife in this area?
Would development disturb any upland areas that are contaminated from
