Why selected?

 Best operational quality for the primary

movements (yellow arrows shown on figure).

 Most favorable comments during the fall

2015 public outreach.

 Requires least additional right-of-way

(8.4 acres)

 Most reserve capacity for high-traffic

conditions.

 Provides desirable trade-off between cost,

property impact, and operational quality.

Estimated cost including real estate:

$28-29 Million

Drainage to Lake Pacawa

 Investigating drainage

techniques to minimize impacts along County B

 Storm sewer water put into

pond north of Lake Pacawa

 Pond then discharges cleaned

water into pipe to Lake Pacawa

 Temporary construction

impacts to Worzella Pines Park Storm water pond location Worzella Pines Park Lake Pacawa
