34. Benefits, Statistics & Summary Pilot project %’s; 30% of areas increase, 32% will decrease, 38% will stay the same. However, 38% ERU will increase, 32% will decrease, and 30% will stay the same. Est. $82,000 increase; final was right on. $88,000 increase in annual Stormwater revenues (currently a $10 million revenue stream and 5,200 non-residential areas) Decrease in credits & debits since accurate, so saves time processing Decrease in GIS Tech time spent on making area adjustments High-impact and accurate picture can now be faxed or emailed to customer for their approval instead of a field check by GIS Tech Since visually Ok now, will add to GIS intranet for Customer Service, Development Service, Engineering, Planning, and all Employees to use instead of passing around the customer for information 1,570 hours for interns cost $20,000 – great ROI Plan for 2 or 3 years to do cursory check again (parking lots!)
