E. PAIRED -PARCEL AVERAGED -DENSITY DEVELOPMENT
1. GENERAL DESCRIPTION
a. Paired -parcel averaged -density involves the use of two (2) noncontiguous parcels and is based on the

development project for the purpose of these watershed regulations.
b. The amount of development allowed for the paired parcels taken in tandem cannot exceed the amount
of development that would be allowed if the parcels were developed and reviewed separately for
compliance with these provisions.

2. DEVELOPMENT IN THE STREAM BUFFER
a. No development is permitted in the buffer except for the following where there is no practicable
alternative to their location in the stream buffer.
b. These permitted activities shall minimize built -upon area, direct runoff away from surface waters, and
maximize the utilization of stormwater best management practices:
i. Water dependent structures;
ii. Utilities;
iii. Transportation facilities, such as bridges and roads; and
iv. Passive recreation uses, such as greenways and open spaces.
3. LIMITED REMOVAL OF VEGETATION
