CSW|ST2 provided site planning and engineering design services for this new 340 unit residential development located on a site previously used as a rock quarry. The project is located on Petaluma Boulevard South and, as a part of the development project, substantial off-site improvements were required. Improvements included upgrading and extending utility service to properties along a 2,200 l.f. segment of Petaluma Boulevard South. Other street and path improvements were included, as well as undergrounding overhead utilities and extending underground utility services.
CSW|ST2 was a key participant in the entitlement process. We provided site planning, civil engineering, landscape architecture, and surveying services. CSW|ST2 prepared the reclamation grading plan that reshaped the topography and set it up for the proposed development project. We also provided a Salt Marsh/Riparian Habitat Restoration and Bank Stabilization Plan for the 30-foot wide River Edge Zone. The eroding bank will be laid back at 4:1 and 3:1 slopes. The entire length (590 feet) along the Petaluma River will be restored to a native salt-marsh and riparian habitat. CSW|ST2 was responsible for obtaining all of the required permits from the environmental regulatory agencies for demolition of existing structures along the river bank, improvement of an existing dock, construction of an elevated boardwalk, bank stabilization, and habitat restoration.
