The Woodlands Neighborhood Green Initiative Infrastructure
In 2005, the Village formed the Drainage and Woodlands Improvement Task Force. From the efforts of this Task Force, the Village commissioned two separate engineering studies to determine options and ultimately their desired approach for improvements to the storm water management and aging/deteriorating infrastructure. Resultant of the engineering studies, neighborhood meetings/input, and anticipated cost implications, the Village of Hinsdale developed the following Goals and Objectives for improvements to the Woodlands Neighborhood.
- Maintain Neighborhood Characteristics
- Minimize Increase in Impervious Area
- Improvements to remain within Existing Right-Of-Way
- Minimize Conventional Storm Water Management (i.e.: pipes, inlets & high-back curbs)
- Maximize Use of Best Management Practice for Infiltration and Storage Benefits
- Minimize/Avoid Impacts to Neighborhood Trees (mature Elms, Oaks, etc. throughout the area)
- Minimum 10 year Storm Event contained within Green Infrastructure System
In 2011 the Village of Hinsdale hired HR Green to design and develop bidding/construction documents for The Woodlands – Green Initiative Infrastructure Improvements – Phase 1. Additional services included topographic and boundary/right-of-way survey, permitting, and construction observation. The existing neighborhood is heavily wooded and has a significant amount of intricate landscaping within the roadway right-of-way. The HR Green project team, consisting of experienced professional engineers and landscape architects, worked closely with the Village Engineering staff, Village Arborist, Village Environmental and Public Services Committee and residents to minimize disturbance to the existing trees and intricate neighborhood landscaping. The green initiatives concepts and designs that were implemented included rain gardens, bio-swales and underground storm water storage with sub-surface infiltration. Environmental benefits include reduction in storm water pollutants, increase in the amount of storm water infiltration.
Additionally, the project design/construction included a new water main, rehabilitated sanitary sewers (CIPP Lined) and reconstructed neighborhood roadways with low-profile concrete curb and gutter and minimal inlets to meet the residents desire to minimize conventional storm water management methods and embrace a low impact philosophy which promotes the preservation and enhancement of the existing neighborhood characteristics.
