• Construct a new intersection as a two-lane roundabout or as a conventional
signalized intersection at Skyline Ranch Road at Main Street South.

• Plum Canvon Road at Skyline Ranch Road/Heller Circle South

North approach· Restripe left-turn lane lo allow the left-turn movement.

East approach: One left-turn lane, one shared through/left-turn lane, and one
right-turn lane.

West approach· Restripe to provide one left-turn lane and one shared
through/right-turn lane rather than one left-turn lane and one nght-turn lane.

An adjacent development (Tentative Tract No. 46018) was conditioned to design
and construct the east approach to provide one left-1urn lane and one shared
through/right-turn lane. We suggest the project's developer work with the
developer of Tentative Tract No. 46018 to combine improvements at the
intersection and coordinate the cons!ruclion schedule of the aforementioned
wor;1 al this 'ocation.

We also generally agree with the study that 1he project along with other related projects
in the area may significantly impact the County intersection listed below. The project
shall pay its pro-rata share of the cost for !he following recommended mitigat'on
measures:

Plum Canyon Ro~d at Golden Valley Road/Santa Catarina Road
l
South approach: Two left-turn lanes, one through lane, and one right-turn lane
rather than one left-turn lane, one through lane, and one right-turn lane.

The project's pro-rata share is 53.2 percent.

For all proposed cumulative mitigation measures, a cost estimate and conceptual plan
shall be submitted to Public Works for review and approval.

We recommend the proJect's developer worl1 with the Sulphur Springs Union School
District to develop traffic circulation plans and drop-off/pick-up procedures for the
proposed school. If possible, we recommend implementing a one-way
counter-clockwise on-sile traffic circulation for any valet service and restricting any site
access from Skyline Ranch Road. The traffic circulation plan should inc!ude
informational packets containing the approved drop-off/pick-up procedures, as well as
