Pond Shoreline Stabilization

Ponds - Primary Function

pond There are over 550 stormwater basins (detention ponds) in the Village that are part of the overall stormwater management system. Approximately 170 of the basins are maintained by the Village. Designed and constructed with the subdivisions, the basins' primary function is to serve as a critical component of the Village’s stormwater management system because developments add more impervious runoff surfaces like parking lots, sidewalks, and roofs. Without these ponds, this extra water would be introduced water to streams/creeks faster and increase flow, damaging natural streams/creek drainage and increasing the impact of flooding on other properties downstream.  These ponds serve as a way to collect the water and slowly release to the same streams/creeks.  They also serve a vital role in protecting homes around the pond from flooding issues.  While there are aesthetic benefits, the main purpose the ponds serve is stormwater management.


Shoreline Restoration Projects

In February 2011, the Village established the Village’s Basin Best Practices Program. The broad goals of this program include:

1.  Establishing a comprehensive and consistent Village-wide approach to basin and basin shoreline management; 
2.  Providing consistency in expectations among all stakeholders;
3.  Utilizing the right resources at the right time provided by the best qualified parties;
4.  Following industry best practices for ecological restoration and maintenance.

Prior to the establishment of the Basin Best Practices program, there had been varying levels of stormwater basin maintenance and management performed by different contractors and a comprehensive strategy has not been developed. The Basin Best Practice programs unified the approach to basin restoration and stabilization of shorelines. 

The primary approach that the Village utilizes for shoreline restoration projects involves the use of native vegetation versus "hard edge" techniques such as sheet piling or stone riprap. Native grasses/forbs have been proven to provide excellent means of erosion control and have been shown to filter out nutrient and sediment runoff from adjacent land, which contributes to improved water quality. The USEPA, US Army Corps of Engineers, the Morton Arboretum, and the Chicago Botanic Garden utilize native plantings as a key component of current shoreline stabilization projects.

 



The main benefits to shoreline restoration projects are:erosion

 

•         Protecting shorelines from erosion.
•         Providing and improving habitat for fish and other wildlife.
•         Improving water quality and filter nutrients/sediments.
•         Attracting natural wildlife.
•         Increasing shoreline stability 

 














Why Shoreline Buffer Strips Work - EPA

Shoreline stabilization: Natural buffers that extend down to the water's edge can be very effective in preventing shoreline erosion. In contrast to 
conventional turfgrass (which is shallow-rooted and intolerant of flooding), natural riparian vegetation has dense, deep root systems that firmly anchor shoreline soils. These native plants also are able to withstand extended periods of inundation that are so common in lakes and reservoirs. Native vegetation performs this function so well that it is now being used, sometimes with other natural materials, to repair eroding shorelines. This approach, known as bioengineering, is a low-cost alternative to conventional engineering solutions such as riprap or seawalls.
