How is Rockville zoned?
Rockville regulates land through 23 zoning districts, and the mixed use family is the most developed part of the roster. Seven districts carry a mixed use designation: employment, corridor district, transit district, neighborhood commercial, business, transition, corridor transition and commercial.
Mixed Use Employment is the largest of them at roughly 496 acres and Mixed Use Corridor District second at about 312. Having both a corridor district and a corridor transition district, and both a transition and a transit district, shows a city distinguishing carefully between where intensity sits and how it steps down.
The residential system states lot size in the code: R-60, R-75, R-90, R-150, R-200 and R-400. R-60 is the largest residential district at roughly 1,295 acres and R-400 covers residential estate land at about 667. Three Residential Medium Density districts, numbered 10, 15 and 25, add roughly 259 acres.
Planned Development is the largest classification overall at roughly 1,310 acres, so a substantial share of the city is governed by approved plans.
A Park Zone covers roughly 854 acres, the fourth largest classification. Light Industrial covers about 184 acres, which is small, consistent with a city whose employment sits mainly in the mixed use and office categories.
