4.2 Cul -De -Sacs <br />A cul -de -sac is a circular turnaround at the end of a short, <br />dead -end street. The illustration to the right depicts a <br />typical cul -de -sac design for the Trace project. <br />• Landscape areas shall be provided within the circular <br />area of the cul -de -sac to include at least one (1) street <br />tree of between z" — 4" caliper. <br />• Cul -de -sacs shall not be more than 450 feet in length <br />unless it is not feasible to design them in any other <br />length. in no case shall the cul -de -sacs in Trace be <br />designed more than 500 feet in length unless <br />approved by the City Engineer for specific reasons <br />concerning site constraints such as avoidance of <br />environmentally sensitive areas, topography or <br />engineering design. <br />• Cul -de -sacs shall have a ROW radius of 6o feet. <br />• Cul -de -sacs shall include sidewalk pedestrian access <br />from the end of the cul -de -sac to the next adjoining <br />street. <br />• Construction of cul -de -sacs shall include proper <br />signage at the entrance to inform drivers that the <br />street is not a through street. <br />4.3 Alleys <br />Older, traditional urban development in cities prior to World <br />War 11 used the alley for garage access extensively. With the <br />popularity of the car, alley designed access for garages <br />became almost obsolete. In keeping with a more traditional <br />neighborhood design at Trace, alleys shall be permitted in <br />Trace but not required in every single instance of subdivision <br />design. <br />• Alleys shall be required adjacent to all lots 40' wide and <br />smaller. <br />• Alleys shall be a minimum of z0' wide <br />• Alley loaded product shall be required along the entire <br />length of Street Section AA and Street Section CC. <br />M, <br />I <br />Lau <br />of <br />4f <br />pen Space (width varies) <br />Sidewalk <br />#w <br />Landscape Island <br />Lou <br />Sac and A(e <br />
