Other Location Info
The proposed project (by CityLine) is located on Subblock 1 which is a part of Block 18 of the DSP. The entire Block 18 is bordered by S. Mathilda Avenue, S. Sunnyvale Avenue, W. Washington Avenue, and W. McKinley Avenue, and includes existing office, retail, and residential buildings. Subblock 1 is bordered by S. Mathilda Avenue, W. McKinley Avenue, Booker Avenue, and the area referred to as Aries Way. Subblock 1 is currently developed with a four-story retail and multi-family building to the east, and a two-story bank building with a surface parking lot to the south (the bank site is not part of the CityLine development). The proposed project includes the redevelopment of the 1.9-acre vacant site located mostly in the north western part of the block.
Other Information
The existing 1.9 acres site is vacant and undeveloped. The perimeter of the site includes streetscape improvements on S. Mathilda and W. McKinley Avenue. No other improvements or development exist on the site except for ground signage. The project consists of a six-story building with one level of underground parking. The ground floor would be two stories in volume (22-foot plate height) and will include retail on McKinley Avenue, Makerspace on Mathilda Avenue, and a lobby along Aries Way. Service areas and access to the ground and second-floor level parking access will be from Booker Avenue. Access to the lower parking level will be from a ramp near the Aries and W. Iowa Avenue intersection. The portion of the lower parking level located south of Booker Avenue is open to above and screened from the street view by three feet six inches tall wall and landscaping.
