Stormwater Control Measure (SCM) Information

Stormwater Design

Section 6.1 of the Apex Unified Development Ordinance (UDO) discusses Town
stormwater regulations. The Town has adopted the NC Stormwater Design
Manual as their stormwater
design manual. Planting requirements for applicable SCMs can be found in the
Town Design and Development Manual
(PDF). All projects must
submit use and submit the latest version of the NCDEQ SCM Supplement EZ
forms
with supporting calculations. Projects in the Neuse River Basin must use and
submit the NCDEQ Stormwater Nitrogen & Phosphorous (SNAP) spreadsheet
tool to meet the required
nutrient reductions.

Construction Sequence

The Town has developed an SCM Construction Sequence
(PDF) to provide specific
information for developers on what is required for SCMs prior to Final
Plat/CO.

Operation & Maintenance (O&M) Agreements
The Town of Apex now requires eRecording for SCM O &M Agreements
The Town of Apex requires that O&M Agreements for SCMs be recorded prior to
plats being recorded. In order to assist developers and surveyors, Apex is
requiring eRecording for O&M Agreements. Effective 1/1/26, the fee for this
service is $41.35 (Wake County Fee + Provider Fee).

The following steps must be completed before Development Services staff will
approve plat signing:

1. E-mail draft O&M Agreement to Development Services for review at christine.masney@apexnc.org.
2. Once draft is approved, deliver hard copy executed O&M Agreement along with $41.35 check to Development Services.
3. Development Services will eRecord O&M Agreement and e-mail recorded agreement to developer.
4. Development Services will write the book and page number of the recorded O&M Agreement on the plat to be recorded.

Annual Inspection Reports

annually by a qualified registered North Carolina professional engineer, land
surveyor, or landscape architect performing services only in their area of
competence. Each SCM owner will receive a courtesy 30-day notice in the mail
from the Town the month before their annual inspection is due.

Annual Inspection Report Guidelines
Please name the single PDF report file with the year, whether the inspection
passed or failed, and the property name. E.g. 2020 SCM Certification - Apex
Town Hall or 2020 SCM FAIL - Apex Town Hall. If a site fails inspection,
the report is still due to the Town by the inspection deadline. A 60-day
period is then granted for repairs. Note that annual inspection reports
submitted are subject to follow-up inspection by Town staff.
