What is the difference between the low- and high-density options?
The high-density development option allows for more built-upon area on a site through the use of stormwater management techniques to mitigate the effects of the increased impervious surface and the resulting increased rainfall runoff. Depending upon the watershed classification, low-density development may allow up to 2 dwelling units per acre (24% built-upon area). With the high-density option, development can potentially reach a 70% maximum built-upon area, depending upon the watershed classification. For a detailed discussion about using the high-density option, refer to Streamlines Vol. 1, no. 3. The water supply watershed classification table has more details regarding low- and high-density built-upon area limits for the various watershed classifications.
