Norwalk approves West High Road subdrain retrofit, awards $192,458 contract to TK Concrete
Summary
After a public hearing, the council approved plan/specs and awarded a $192,458 contract to TK Concrete to install subdrains and backfill on West High Road as a pilot to capture subsurface moisture and extend pavement life.
The Norwalk City Council closed a public hearing on Aug. 21 and approved a three-resolution package to start a pilot subdrain retrofit on West High Road aimed at capturing subsurface moisture and extending pavement life.
Staff described the project as a targeted storm-sewer and subdrain installation rather than a full pavement reconstruction. The work will remove limited curb and gutter along portions of the street to install subdrains behind the curb, perform localized patching of broken panels and backfill to improve the subgrade. Staff emphasized that this is a pilot retrofit intended to test whether subdrains can meaningfully reduce subsurface moisture migration and slow pavement deterioration.
During the public hearing resident Arthur Proudly of Redwood Drive asked whether the project would cause water to back up into his yard; engineering staff explained local drainage patterns and said the retrofit would neither negatively nor positively affect his property in the project area as described.
Council then approved by roll call: (1) a resolution approving the final plan, specifications, form of contract and estimate of cost for the West High Road subdrain retrofit; (2) a resolution awarding the contract to TK Concrete in the amount of $192,458; and (3) a resolution approving the contract and bond and indicating the city’s method of payment. The council passed each resolution with no recorded objections.
Engineers reading Wayne’s prepared answers explained that the retrofit differs from nearby Ridge-area reconstruction because the Ridge pavements are in far worse condition and would require full reconstruction rather than a retrofit. Staff also said they are updating subdivision standards to require subdrains and granular backfill for new roadways where appropriate, but implementation timing and whether to apply standards retroactively would be a future council decision.
The contract award to TK Concrete begins the pilot phase; staff said the project is one of three steps the council needed to authorize construction. No schedule for construction start was given in the hearing record beyond standard contracting timelines; council authorized staff to proceed under the approved contract and bond terms.
Next steps: staff will manage contract execution and return to council if further approvals or scope changes are necessary.
