RE: Stream Determination for Trinity Court, Chapel Hill, NC
PIN 9788-19-4511
Dear Emily:
As requested, the Town Public Works Department has performed a stream determination for the property
identified on the attached forms. This determination indicates whether different types of streams (perennial,
intermittent, and/or ephemeral) or perennial waterbodies are present on the property in question or on
nearby properties. These streams and their classifications are shown on the accompanying map. Stream
segments regulated by the Town's Jordan Lake Watershed Riparian Buffer regulations are highlighted.
Locations of all features on the map are approximate and must be field surveyed for precise location.
This stream determination information is used to determine the location and extent of the Resource
Conservation District (RCD) and Jordan Lake Watershed Riparian Buffers. Specific land use regulations and
restrictions apply within the boundaries of these protected areas. If you are considering any kind of work on
this property, including clearing vegetation, paving, grading, or building, please consult with the Town
Planning Department to determine the possible extent of the Resource Conservation District (RCD) and Jordan
Lake Watershed Riparian Buffer on this property and the applicable corresponding regulations.
This stream determination will remain in effect for five years from the date of the site visit, after which a new
stream determination with site visit will be required.
In accordance with the Town's procedures, you may appeal this administrative decision to the Town Manager.
If you wish to do so, you must file your written appeal accompanied by any materials you believe support
your appeal, within 30 days of receipt of this letter.
If you have questions regarding stream determinations, please contact me at [phone] or
[e-mail]. If you have questions regarding the Town's Resource Conservation District
(RCD) or the Jordan Watershed Riparian Buffer regulations, please contact the Planning Department at (919)
968-2728, or view information online at: http://www.townofchapelhill.org/stormwater.

Allison Schwarz Weakley

Trinity Court, Chapel Hill
These are the results of a site visit to the properties listed above for a stream determination
conducted on 7/16/2020 by Town Staff:
n No perennial, intermittent, or ephemeral streams or perennial waterbodies were identified
on or near the property(ies) in question.
171 Perennial, intermittent, or ephemeral streams, or perennial waterbodies, were identified on
or near the property(ies) in question and shown on the attached map(s).
A map showing water features, their Town flow classifications, presence of Jordan Watershed
Riparian Buffers, and their approximate locations is attached. Origins or breakpoints that
have been flagged in the field are marked on the map. Stream classification forms and
additional site visit notes and maps are also attached.
Other conditions exist which may affect the location of the Resource Conservation District or
Jordan Watershed Riparian Buffer:
M FEMA floodzone is mapped in the area. Precise location of the Base Flood Elevation and
associated Resource Conservation District must be determined by a field survey commissioned
by the owner or a representative.
M Segments of perennial or intermittent stream are piped in the area, as shown on the map.
These segments do not have an associated Jordan Watershed Riparian Buffer.
n Possible Jurisdictional Wetlands have been identified in the area. A formal review by a
professional certified in Jurisdictional Wetland Delineation is recommended if impacts to
wetlands are anticipated.

REQUEST FOR STREAM DETERMINATION
Stream determinations provide information used to determine whether the Town's Resource
Conservation District (RCD) or Jordan Watershed Riparian Buffer Protection regulations apply to a
property. Town staff will typically conduct a field visit to classify streams on the property(ies) indicated
below within two weeks of a request, depending on weather conditions, staff availability, and scope of the
request. Please note that stream determinations cannot be conducted within 48 hours of a rain event.
There is no fee for stream determinations conducted by Town staff.
A stream determination report indicates the results of a stream classification. Stream classifications expire
after five years. If a stream determination has been completed on or near the property(ies) listed below
within the last five years, a site visit may not be required unless local hydrology has changed significantly
or the stream classification has expired. If a site visit is not required, the stream determination will be
based on a records review.
Requests may be emailed(aweakley©townofchapelhill.orq), faxed, dropped off at Town Hall or the
