Trinity Parkway Phase II Project

Trinity Parkway Phase II Project

With the Trinity Parkway Phase II Project, the remaining two lanes of the four lane arterial would be constructed between Bear Creek and Otto Drive but would be restricted from travel. The Phase II project would extend Trinity Parkway to the south of Otto Drive. This section of the roadway is proposed for construction as a four lane arterial and would terminate at Mosher Slough. Vehicular travel on this segment would be restricted pending subsequent environmental review. An important component of Phase II involves the alteration of the alignment of the dry land levee that extends along the western edge of the Trinity Parkway right of way (in a north-south direction). Dry land levee realignment of up to 300 feet to the west, as measured from western toe of the existing levee to western toe of the realigned levee, is required to construct the complete four lane arterial cross section of Trinity Parkway from Bear Creek to Mosher Slough. At the Otto Drive intersection, Trinity Parkway will be elevated slightly in anticipation of the future entrance into the proposed Atlas Tract (The Preserve) development project. Trinity Parkway will also be evevated at the southern end of the project to meet the height elevation of the new Atlas Tract levee system and future Mosher Slough-Trinity Parkway bridge. The dry land levee is currently under the jurisdiction of the State Reclamation Board and the Army Corps of Engineers and this project will require their approval prior to the levee's realignment. In the summer/fall of 2006, the Atlas Tract levee system was improved to provide flood protection estimated to be in excess of the 200 year flood event. Based upon those improvements, the Federal Emergency Management Agency (FEMA) has recently issued a Letter of Map Revision demonstrating that the site now has flood protection exceeding the federal minimum. With the enhanced levee system in place, lands within the Atlas Tract will be protected from tidally influenced delta flood waters, as well as the upstream flooding potential from Bear Creek and Mosher Slough. The Atlas Tract levee system improvements will also provide the existing residential users in the Twin Creeks Estates subdivision continued flood protection in addition to the protection afforded by the dry land levee, thus allowing for levee realignment to occur without risk to the Twin Creeks Estates residents and construction of Trinity Parkway improvements. Included in the proposed roadway improvements will be utility pipes, water, sewer, streetlights, and PG&E joint trench facilities.
