Wayland Assisted Living Facility

The Project is located on the 9.57-acre Lee’s Farm Site at 134 Boston Post Road (Route 20) in Wayland, Massachusetts. The project includes
approximately 35,600 square feet of assisted living and memory care space in a facility with associated parking and access in addition to site, landscape, pedestrian, drainage and utility infrastructure improvements. The site will be subdivided into two parcels, one to facilitate the project and the other will remain as an existing agricultural use with a farm stand. In an effort to minimize impacts on both parcels and maximize land area associated with the agricultural use on the farm stand parcel, many of the utility infrastructure improvements will be shared including the soil absorption system for wastewater treatment and the stormwater system. Both are designed to provide for future site and utility improvements on the farm stand parcel.

The proposed development follows the general slopes of the existing site, and has been designed to capture and manage all stormwater runoff from developed areas on-site. The layout of the site has been designed to maximize the agricultural area on the farm stand parcel, limit the impacts to existing mature trees, and minimize impervious areas via reduced drive aisles. In addition, the soil absorption system has been located where subsurface soils allow and the wastewater and stormwater management infrastructure will be shared between the two parcels. The proposed development has been designed to direct stormwater runoff from the proposed building and impervious surfaces to an infiltration basin to collect and treat surface runoff prior to recharge to groundwater. Runoff on the site is primarily collected in the closed drainage system by catch basins and then discharges into pretreatment basin prior to entering the infiltration basin. Pervious concrete sidewalks are an LID feature used on the site.
