PAVERS
passing 58 acres. This facility is still in operation on a portion of the site. As part of the construction of the disposal facility, chain-linked fencing topped with barbed wire was installed in the middle of the pier for safety.
Commensurate with the redevelopment of many of our nation's waterfront areas in the 1980s, the Lorain Port Authority, in association with the City of Lorain, prepared a master plan to guide the redevelopment of the pier, confined disposal site and landslide areas. This plan provided for the development of a 600-slip marina, public parking and relocation of the chain-linked fence to promote public access and usage. These features were constructed in 1988.
20 years later
DURING 2007, the Lorain Port Authority updated its master plan for the pier and disposal site area. This new plan called for mixed-use development in the area, expansion of public parking along the eastern edge of the pier, shore-bird habitat restoration, open space and development of a nature center. As part of the master plan, landscape architects Behnke Associates Inc. proposed three phases of development for what is now referred to as Lakeside Landing. The first phase mainly consists of a "face lift" to the 2332-foot-long dike, particularly the concrete cap that became a high priority.
It was determined immediately that removing and replacing the two-foot-thick concrete cap with a more attractive pavement was not cost effective. The concrete cap provided an important structural purpose, even though it had become cracked and uneven since being built in 1964.
Other considerations for a new pavement were issues dealing with severe weather such as
Permeable Pavers in Action
Visitors to New Albany, Ohio, find themselves in a classic small town: miles of white horse fencing and beautiful brick homes lead to a down town city center. There, a new brick road is carrying more than traffic.
Made of Pine Hall Brick's Storm-Pave permeable clay pavers, the new Third Street enables storm water to infiltrate and recharge the water table, instead of washing pollutants across the surface into nearby storm drains or waterways. It's made of clay brick pavers that naturally are green, since they're made of clay and water, the most abundant building materials on the planet. Brick pavers also are green because they last for centuries, and are an example of naturally sustainable construction.
But moreover, planners found that it cost virtually the same to put in a permeable paver street as it would have for a conventional asphalt street.
The story began when city officials determined that Third Street needed to be totally reconstructed. The city decided to find out if a material was available that would be more sustainable and environmentally friendly than asphalt.
To put in a conventional street would require new asphalt, conventional curb inlets and underground storm sewer piping, as well as patching and other maintenance in the years to come.
Permeable paver systems require that layers of graded aggregates be hauled to the site and layered for the base, large to small, before the pavers are installed. Once in, the smallest aggregate is swept in the joints. The only required maintenance is that the pavers be vacuumed occasionally to remove debris that would otherwise clog the system.
The bottom line? The costs of putting in permeable pavers came in at $424,389. The estimates for putting in asphalt including five years of maintenance was at $427,718; maintaining it for 10 years raised it to $434,085.
Using permeable pavers goes beyond cost. Brick streets have an aesthetic appeal to many potential residents, and their use often negates the need for additional stormwater retention.
Businesses planning new developments near the Village Center will, therefore, have fewer stormwater issues to engineer as a result of New Albany's stormwater mitigation strategy, of which Third Street is a part, town officials said in a prepared statement.
Another advantage? "These new pavers will drain better, producing less ice on the surface," says Public Service Director Mark Nemec. "Plus, brick streets typically calm traffic, so we expect a safer environment for motorists and pedestrians alike."
