PROVO PARKING LOT DESIGN Clifton Hargus, Rachel Bytheway, Derek Noyes

Outline  Background  Project Goals  Research  Drainage Requirements  Designs  Final Recommendation  Cost Analysis

Background  Pavement Severely Failing  Not Enough Parking  Insufficient Drainage

Goals  The parking lot needs to be designed with better drainage.  Parking spaces need to be arranged to obtain the maximum number possible.  Multiple construction phases should be considered.

Research  Survey of Site  Coring of Asphalt  Inspection of Current Drainage  Drainage Calculations
