Greenburgh's Planning Board received updated plans for the 55 Grasslands Road residential expansion, focusing on roadway adjustments, stormwater, and tree removal mitigation. The applicant requested more time for a full presentation at a future meeting.

Catching Up

Bethel-Knolls, the operator of The Knolls continuing care retirement community (CCRC) at 55 Grasslands Road, proposes 75 new independent living units and an auditorium to enhance its community. This expansion aims to maintain market competitiveness and financial stability. The project requires rezoning from its current Planned Unit Development (PUD) district to an R-30 One-Family Residence District and involves building onto existing structures. Variances are also being sought for several building aspects.

Key Insights

The Planning Board reviewed revisions to the 55 Grasslands Road expansion, detailing changes to site layout and environmental management.

  • The roadway for 55 Grasslands Road was moved to increase buffering around the property.
  • Stormwater management will now use a single infiltration basin, designed to handle a 9.1-inch rain event.
  • The updated tree survey for 55 Grasslands Road indicated approximately 100 trees for removal, which will be mitigated by reduced site disturbance and new evergreen screening.

Zooming In

The existing Knolls community at 55 Grasslands Road currently offers 120 independent units, 10 assisted living beds, and 20 skilled nursing beds on a 29.2-acre parcel. The proposed expansion is designed as two stepped-down structures, one reaching 2 to 2.5 stories. The Historic and Landmarks Preservation Board has advocated for the preservation of an 1870 Italianate farmhouse on the 55 Grasslands Road site.

Next Steps

The applicant for the 55 Grasslands Road project requested additional time to prepare for a comprehensive presentation at a subsequent Planning Board meeting.
