Winnetka · Public project evidence
School and park land become stormwater storage
The west-side program links a Council-approved plan and intergovernmental agreements to storage under athletic, golf and school land.
Documented status: Storage built; program phases require separate checks. Evidence dated . Later outcomes require a later source.
What the source records establish
Source record
Coordinate across schools, parks and agencies
The Village describes agreements with New Trier, District 36 and the Park District, plus external project approvals.
Source record
Use open land for underground storage
The source states storage was built under Duke Childs Field, the golf course and behind Crow Island School.
Source record
Release collected water gradually
The system is designed to convey water into detention and slowly release it to the Skokie Lagoons during major storms.
Proposals and possible effects
Possible effect
Benefits depend on drainage connections
Nearby land is not automatically within a protected drainage area; hydraulic service boundaries and remaining conveyance work need verification.
Properties and geography
Duke Childs Field, Winnetka Golf Course and Crow Island School area. Scope: town-wide. A place or street reference is not an affected-property boundary.

Conditions and public commitments
Possible effect
Benefits depend on drainage connections
Nearby land is not automatically within a protected drainage area; hydraulic service boundaries and remaining conveyance work need verification.
Contracts, permits and completion evidence
A distinct contract, permit, payment or completion record has not been summarized in this edition. Approval and proposed work alone do not establish completion.
What changed in this edition
The permanent timeline brings the previously reviewed source records together with funding references, conditions and property context. It does not assert a new project decision or completion after the evidence dates shown above. Future material updates will identify the changed claim and its source.
Open questions and next records
- Join the as-built storage and conveyance network to verified drainage areas, not a radius around the school or golf course.
