Abstract: A one-piece elastomeric spring having four spaced end portions all joined to and extending from a common body portion. Two end portions are commonly disposed to each side of an axis of the spring such that each end portion can independently deflect when a force is applied thereto. The one-piece spring is formed from a preform formed from an elastomer which is normally free of spring-like characteristics. The elastomer from which the preform is created has a molecular structure along with a ratio of plastic strain to elastic strain greater than 1.5 to 1. The molecular structure of the preform is oriented in at least one direction so as to allow a predetermined spring rate to be imparted to the preform whereby transmuting the preform into an elastomeric spring.

Abstract: A stormwater pollution management apparatus for a stormwater basin including a water intake assembly having a first end and a second end generally aligned along an axis and includes a hollow inverted T-shaped connector.

The axially elongated intake defines a series of openings along the length and about the periphery thereof. An outlet projects in a second direction from a second side of the T-shaped connector toward the second end of the water intake assembly. A wrapper extends along and about the generally horizontal intake for creating an energy differential between the sediment water flowing into the water intake assembly and the water in the basin thereby affecting separation of particulate sediment from the water flowing into the water intake assembly. A hollow riser extends upwardly from the connector.
