Four Seasons Calistoga

OVERVIEW
Four Seasons Calistoga is a substantial multi-purpose development of a 23-acre parcel that will include two inns, commercial space, a spa, swimming pools, a vineyard and wine cave, and a below-grade parking deck. Langan performed a geotechnical investigation and a limited environmental site assessment for the proposed development. As part of our services, we performed a hydrogeologic study to evaluate the potential flow discharge rate arising from the basement wall back drain and underslab drainage system during heavy rainfall.

144 King Street

OVERVIEW
The 12-story King Street hotel is in the SOMA district across from AT&T Park. Langan performed a geotechnical investigation to provide foundation and excavation recommendations for the hotel. To safely excavate, the contractor installed temporary shoring of tied-back soldier-pile and lagging under our observation. Langan's environmental team performed a site characterization, prepared a Site Mitigation Plan in accordance with the Maher Ordinance, and observed soil off-haul operations, resulting in the project receiving clean closure from regulators.

950 Market

OVERVIEW
The existing building at 950 Market is being demolished to construct a 12-story development that consists of a hotel, residential units, and retail. Langan is providing multi-disciplinary services. Because the structure comprises the majority of the site, an important aspect of our site/civil engineering services is the stormwater management design. The site is adjacent to BART and MUNI tunnels, which was a key consideration in providing appropriate recommendations for foundation and shoring design. The development is subject to San Francisco's Article 22A (Maher) Ordinance, which requires that site history and soil sampling be performed.

The hotel, constructed in the 1920s, is a multi-level structure ranging from three to six stories. Langan performed site-specific ground motion analysis, recommended suite of time histories, and foundation design parameters for the hotel site rehabilitation, as well as a geotechnical investigation and studies that addressed necessary improvements.
