Horizon Flats Road serves the Towns industrial/manufacturing area as well as a growing residential community. The existing street requires yearly maintenance to keep operation during the Spring thaw due to poor drainage and pavement condition. Heavy truck traffic, sharp curves and inclines increase maintenance and safety concerns. Springtime closures and weight restrictions have been considered but difficult to implement due to their detrimental impact to area businesses and major Town employers. Lack of an ezisting stormwater collection system and steep roadway and adjacent land slopes create erosion and flooding issues for both the roadway and surrounding properties.

Project Description
***Updated Scope Approved 5/19/2023 Board Action*** Three distinct sections and revised drainage solution. Stormwater will be collected with catch basins and conveyed to drywells. Additional capacity for overflow will occur at a recently constructed swale near the new fire station (mid section vicinity). The intent is to avoid slope erosion particularly on the upper section where 21 side slopes exist. The pavement scope is different for each section Lower section - Twin Lakes Road to 1000 feet south (first curve vicinity) - pulverize existing asphalt, regrade roadway crown, 5” crushed surfacing top course (CSTC), and overlay with 3.5” of Hot Mix Asphalt (HMA). Mid section - between curves – install 12” perf pipe from catch basins to a down gradient drywell and existing swale adjacent to the fire department property. Full depth shoulder widening and 0.15’ full section HMA overlay. Upper section – Second Curve vicinity to project limit – Widen shoulders with 4” CSTC and 1.25” HMA. 0.15’ full section HMA overlay.
