The Jackson Planning Commission will be holding two public hearings tonight regarding lot splits. The first proposal is by Sandy Nurse on the behalf of Sierra Foothill Labs. The applicant is proposing to divide the 2.8 acre lot located at 255 Scottsville Drive into two smaller lots, with one 49,169 square feet and the other 41,426 square feet. The existing site is currently the home of the Sierra Foothill Labs laboratory facility.
