In nonresidential areas, the turnaround shall have a minimum right -of -way diameter of 100 feet and a paving surface with a minimum width of 90 feet. Islands shall be allowed within cul -de -sacs with a minimum diameter of 20 feet for the island. (o) Construction of Streets. Except as modified herein, all streets shall be constructed in accordance with paving widths and specifications as set forth in the TCSS of the City of San Marcos at the time at which the preliminary plat application is officially submitted and deemed a complete application, except as modified within this PDD. (p) Street Grades and Horizontal Curves. Street grades will conform to standards set forth in the TCSS Manual, except where topographical constraints exist these may be exceeded on a case -by -case basis, as approved by the Director of Development Services.
