Client: Montgomery County Department of General Services & The Peterson Companies
Location: Silver Spring, MD
Located in a very densely populated urban area, Downtown Silver Spring was the largest Public-Private redevelopment partnership in Montgomery County at the time of its development. The project consists of over 700,000 SF of high-end retail, anchor stores, office, hotel, and multi-family residential space. The project also includes the Silver Spring Civic Building – the epicenter of Silver Spring’s community activities and events, two parking garages and a surface parking lot. A multitude of known and unknown existing utilities running through the existing streets posed significant design challenges and made management of uninterrupted utility service a paramount concern. The lack of available space for stormwater management facilities posed a significant design challenge. Safety was also a concern as some streets had to remain entirely or partially open to vehicular and pedestrian traffic during construction.
The project was segmented into four major phases of development. Soltesz broke each of the major phases into multiple sub-phases so that disruptions to vehicular and pedestrian traffic, as well as utility service, were at a minimum. Soltesz coordinated extensively and worked diligently with the dry utility companies and consultants to locate and identify existing utilities and design new utilities as needed. Soltesz also designed temporary traffic control plans that allowed for sections of each sub-phase to be completed expeditiously. This solution limited sidewalk and street closures as well as provided temporary roadways and walkways during construction. The firm also provided a sequence of construction that allowed for utility work to take place in the evenings or the weekends to avoid interruptions. To overcome the challenge of meeting stringent stormwater management requirements in the tight and complicated urban site, Soltesz navigated the client through various options and proposed multiple, innovative, proprietary underground stormfilters in the parking lots and public streets. Montgomery County approved the use of the first cartridge stormfilters per Soltesz’s recommendation.
