Subject: Stream Buffer Determination
Wimberly Road Properties
Primary Watershed —Jordan Lake Watershed
Dear Mr. Mitchell,
On July 17, 2014, 1 visited the subject site with you to review drainage features as shown on the
USDA Soil Survey and/or USGS Topographic maps and determine if they were subject to the
Town of Apex (Town) riparian buffer rules. Based on the information obtained during the site
visit and per the requirements set forth in Section 6.1.11 of the Town Unified Development
Ordinance (UDO), I have determined the following riparian buffer widths as summarized in the
table below and shown on the attached map titled, "Wimberly Road Properties".
Drainage Shown as Shown asDetermination made Determined Buffer
Feature on USGS on Soil in the field Width
Survey
Feature A Perennial Perennial Perennial 100 Feet
Feature B Intermittent Perennial Perennial 100 Feet
Feature C Not Present Intermittent Not Subject 0 Feet

Feature D Not Present Intermittent Ephemeral (16.25 Pts) 0 Feet
Feature E Not Present Intermittent Ephemeral (16.5 Pts) 0 Feet
Feature F Not Present Intermittent Ephemeral (6.0 Pts) 0 Feet

This on-site determination shall expire five (5) years from the date of this letter. Landowners or
affected parties that dispute a determination made by the Division of Water Quality (DWQ) or
Delegated Local Authority in the Jordan Lake watershed may request a determination by the
DWQ Director.
An appeal request must be made within sixty (60) days of date of this letter or from the date
the affected party (including downstream and/or adjacent owners) is notified of this letter. A
request for a determination by the Director shall be referred to the Director in writing c/o Ian
McMillan, DWQ Wetlands/401 Unit, 1650 Mail Service Center, Raleigh, NC 27699-1650.
Otherwise the appeal procedure will be in accordance with LIDO Section 6.1.11.
If you dispute the Director's determination, you may file a petition for an administrative
hearing. You must file the petition with the Office of Administrative Hearings within sixty (60)
