AGENDA ITEM III: Regular Scheduled Business

Item A.1 – Discussion and Presentation Concerning the Kenilworth 2023 Infrastructure Phase II Planning

Chairman Lien welcomed representatives from Terra Engineering, Jamil Bou-Saab, and Siamak Malek and stated they would provide an overview and update regarding the design engineering for Phase II of the Kenilworth 2023 Infrastructure Green Streets program. Mr. Bou-Saab thanked the Committee Members for the opportunity to meet again and noted Terra had made considerable progress since the February Public Works Committee Meeting. The design plans and street profiles were completed and being submitted to local utility companies for review and comments. Mr. Bou-Saab briefly described the design plans and street profiles to Committee Members and specifically noted Terra is looking forward to coordinating with local utility companies to ensure the utility relocation phase goes smoothly.

Mr. Bou-Saab then turned the presentation over to Mr. Malek, who began by describing what a traditional flooding relief project of this scale would consist of. Traditionally, this type of project would include removing the old infrastructure and replacing it with a larger system but maintain the same characteristics without addressing issues such as sewage back up or overland flooding. Mr. Malek believed Kenilworth was wise by taking a proactive approach in considering a green streets program that addresses environmental and flooding concerns.

Mr. Malek continued by describing the potential road surface solutions the Village could adopt for Phase II of the Kenilworth 2023 program. One option was porous asphalt, which was implemented for Phase I. Mr. Bou-Saab briefly cited a few lessons learned from Phase I and how Terra has investigated possible solutions with regards to porous asphalt. Mr. Malek proceeded by describing a second potential solution, porous pavers. Mr. Malek noted a few examples of where porous pavers were found to be successful and provided an overview of how porous pavers function in a green infrastructure system.

Committee Members inquired how porous pavers differ from other types of pavers. Mr. Malek explained porous paver functions similar to porous asphalt by allowing water to travel through the cracks of the pavers and into the ground. Other pavers, such as a brick paver do not allow for water to gravitate through the surface and does not serve as a green infrastructure option.

Mr. Malek then described another potential solution to be considered, a hybrid system. A hybrid system combines elements from a traditional infrastructure system and a green infrastructure system. The road surface would include traditional hot mix asphalt pavement and a green infrastructure system underneath the roadway, similar to what was implemented in Phase I. Mr. Malek cited information from his research and provided the advantages and disadvantages of this solution.

Terra Engineering representatives continued by explaining their cost-benefit analysis research. They noted the factors considered while conducting their research and made sure each potential solution was being compared equally.

Upon the conclusion of the presentation, the Committee Members discussed and debated various

39 items that included project constructability, project timeline, lessons learned from Phase I, approach for public outreach, and other various design ideas. The Committee reached a consensus and directed Terra to research the hybrid option in greater detail and requested to have additional information at the next Public Works Committee meeting.

Chairman Lien thanked the Terra Engineering representatives for the informative presentation and noted the next scheduled Public Works Committee meeting would be scheduled once additional information is available.

Item A.2 – Discussion Concerning the 5-Year Capital Projects Plan

Due to time constraints, agenda item A.2 was tabled to the next Public Works Committee meeting.

AGENDA ITEM IV: Business from the Public

Chairman Lien opened the floor to anyone in attendance that had any business for the Committee. No one came forward to address the Committee.

Chairman Lien asked if there was any further business to be considered. Hearing none, he opened the floor for a motion to adjourn.

AGENDA ITEM V: Adjourn

There being no further business to discuss, Trustee Bedwell offered a motion to adjourn the meeting, and Trustee Shadek seconded the motion. Upon the results of a voice vote, Chairman Lien declared the meeting adjourned at 9:59 p.m.
