Efficient Parking Lot Design Recommendations for Better Drainage

This project outlines the background, goals, research, drainage requirements, various designs, final recommendation, and cost analysis for redesigning a failing parking lot with inadequate drainage. The study compares Curb and Gutter, Channel Drain, and Box Drain systems, ultimately recommending an affordable option with adequate drainage and minimal construction impact. The final design optimizes parking space usage, allows for multiple construction phases, and addresses landscaping protection concerns.

  1. Provo Parking Lot Design Clifton Hargus, Rachel Bytheway, Derek Noyes

  2. Outline • Background • Project Goals • Research • Drainage Requirements • Designs • Final Recommendation • Cost Analysis

  3. Background • Pavement Severely Failing • Not Enough Parking • Insufficient Drainage

  4. 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.

  5. Research • Survey of Site • Coring of Asphalt • Inspection of Current Drainage • Drainage Calculations

  6. Drainage Requirements

  7. Curb and Gutter • Provides Excellent Drainage • Protects Landscaping from Automobiles • Aesthetically Pleasing • Significant Earthwork Required to Reverse Existing Slope • Double Amount of Piping • Difficult for Multiple Phases

  8. Curb and Gutter Costs

  9. Channel Drain • Continuous Grate for Quick Drainage • Resistant to Clogs

  10. Channel Drain Costs

  11. Box Drain

  12. Box Drain • Provides Adequate Drainage • Works with Existing Slope • Minimal Construction Impact • Provides No Protection for Landscaping • No Curb and Gutter • Requires some Maintenance

  13. Box Drain Costs

  14. Box Drain System Final Recommendation • Significantly Less Expensive • Provides Adequate Drainage • Minimal Construction Impact • Allows for Construction Phasing

  15. Final Cost Analysis

  16. Parking Space Optimization • 8.5’X18’ Parking Stalls • 56 Spaces Needed • Excavation of 400 Sq. ft. • 57 Spaces Provided

  17. Construction Phases • North or South Side Completed First • Catch Basin and Manhole Tie-in Completed During First Phase • Remainder to be Completed as Funds Allow • Each Subsequent Phase to Tie into Previous Work
