Hi Leeders, Option 1a for Infill Site determination stipulates the following: "At least 75% of [the project site] boundary borders parcels that individually are at least 50% previously developed, and that in aggregate are at least 75% previously developed." How does one calculate to what extent a bordering parcel is previously developed?

Ilan, you apply the 'previously developed' definition to each parcel. In other words, how much of each parcel has been altered by construction, paving, or use of the land that would normally require permitting, either currently or in the past. Note that one acre or smaller parcels can be considered 100% previously developed if just one building or similar improvement has been constructed on them. For parcels larger than one acre it's necessary to calculate the amount of land occupied by the previous development footprint and land alterations associated with that footprint. The 'previously developed' definition also includes other detailed guidelines. Eliot
