• This excludes students who attend out of district or a private school (about 13% of the total elementary students in Stapleton). Includes students attending any DPS school • For reference, currently about 20% of Stapleton residents choice out of Westerly Creek, Roberts, and Swigert to another DPS school 4

The number of units sold North of I-70 depends on the housing market and the product type. We assume 400+ units sold each year going forward The single biggest driver of DPS enrollment growth is single-family new home construction. Recent estimates from Forest City (Feb 2013) indicate that the remaining units South will be sold in 2013 6

• Type of unit count matters because the majority of the students are coming from single-family detached units • Unit types north of I-70 are projected to be similar to those south of I-70 • Data source: residential units and sales from Forest City (updated Feb 2013)

Overview of the Yield Metric
“If there are so many kids on our block, why is the DPS yield so low?” Only Pre-K – 12 Students attending a DPS school count towards the yield Age

In planning seats, DPS projects Stapleton single-family yields 20-40% higher than Highlands Ranch and other neighborhoods, which is an aggressive assumption For Denver County the student yield for all residential units is 0.26, for Stapleton we are assuming up to three times that yield As of the last census, roughly 87% of Stapleton-area elementary children attended DPS schools, meaning that 13% of students attended private school or another district. We have assumed 90% capture rates for the other developments DPS-wide 84% attend a DPS school. In more affluent communities such as Cory Merrill, the capture rate across grades is as low as 63% 9

Filing 2 (Aviator Pool area) and Filing 6 (Puddle Jumper Pool area) are the areas that Forest City developed first and are typical of the unit mix of the rest of Stapleton. Even at full build-out, 50% of single family homes in filing 2 do not have any kids in DPS Affordable housing apartments have an average student yield of 0.61.

A significant data point to the belief that South Stapleton yields will max out in the next couple of years is because there are few homes left to sell and we are now seeing Kindergartners from the 2008-2010 timeframe
•
We have seen the decrease in new home construction play out in the 2010 forecast numbers. The largest population for children under 18 was in the 3 year old age group.
