Concar Shopping Center

San Mateo's Concar Shopping Center near near the Hayward Park Caltrain Station will be transformed from an outdated shopping center into housing and retail space - Passage at San Mateo. Mixed-use development will have 935 residences and 35,000 square feet of retail space. The site is the current location of Trader Joe’s, Peninsula Ballet Theatre, 7-Eleven, Shane Co., Ross Dress for Less, TJ Maxx and Rite Aid stores. The future plans suggest retaining a Trader Joe’s and 7-Eleven. The builders plan to have 1,291 residential parking spaces, 102 visitor spaces and 195 retail spaces which is probably would be not enough to keep all the cars of future residents on site.

Not long ago the owner of the Rite Aid Pharmacy in San Mateo is suing the developer of a large office complex under construction nearby, saying that dewatering at Hines office complex project caused the store’s floor to sink up to 9 inches in some places, resulting in extensive damage.

Dewatering involves temporarily removing water from the ground around a construction site. If you dig a hole deeper than the water table, the hole will fill up with water, like it would if you dug a hole in the sand near the ocean.

When builders excavate below the groundwater table, they often first sink small wells around the perimeter of the hole to lift water out of the soil. That lowers the water table in the construction site and prevents the excavation from filling up with water. Depending on the type of soil and geology under the sites, it can also cause settling under neighboring buildings.
