Finding APPLICANT/ADDRESS The Richman Group of California 7817 Herschel Avenue, Suite 102 La Jolla, CA 92612 PROJECT LOCATION The project site is located three blocks south of the I‐210 freeway and adjacent to the Monrovia Gold Line station to the north, Duarte Road to the south, Magnolia Avenue to the west, and a recyclable materials collection facility to the east. PROJECT DESCRIPTION The Station Square South Specific Plan is a plan for a 3.79- acre (gross) property adjacent to the Gold Line Monrovia Station. The development will be a transit-oriented, multi- family residential development of 296 dwelling units, yielding a density of 78 dwelling units per acre (gross). The project includes a private pool courtyard with spa, fitness room, lounge, bike “barn” including a bike work station, fire pit, community kitchen, a dog run, three private courtyards, a public open space area, and a six-story (seven-level) parking structure. The dwelling units will be market-rate apartments.
