• Town of Apex citizens and customers
Implementation
• Stormwater Ordinance (UDO Section 6.1)
The Town of Apex has adopted a watershed protection ordinance to ensure the
availability of public water supplies at a safe and acceptable level of water quality and to
minimize sedimentation of streams. The latest revisions were completed in 2013. The
most recent version can always be found on the Town of Apex website. The executed
ordinance is kept in the administrative offices of the Town Clerk.
• Riparian Buffers
Section 6.1.11 of the watershed protection ordinance discusses riparian buffer
requirements within Apex corporate limits.
There are 100' buffers on perennial streams consisting of 3 zones:
o Zone 1— 30' from top of bank
o Zone 2 — 20' from end of Zone 1
o Zone 3 — 50' from end of Zone 2
There are 50' buffers on intermittent streams consisting of 2 zones:
o Zone 1— 30' from top of bank
o Zone 2 — 20' from end of Zone 1
Apex has jurisdiction over all riparian buffers outside of Zones 1 and 2 of streams in the
Neuse river basin. Within the Neuse basin, DWQ regulates Zones 1 and 2 and Apex
regulates Zone 3 (where applicable). Apex regulates all zones of stream buffers in the
Last updated: 10/26/2018

corporate limit areas within the Jordan Lake basin. A table of uses allowed within riparian
buffers is given on page 12 of UDO Section 6.1.
A "No Practical Alternatives" form is required to be submitted to the Town by anyone
undertaking uses in Apex -regulated riparian buffers designated as "allowable" or
"allowable with mitigation" in the table of uses. If mitigation is required, a "Buffer Impact
Justification and Mitigation" form must also be submitted to the Town.
• Stormwater BMPs
Section 6.1 of the Town UDO provides the Town legal authorityto require structural BMPs
on all development and redevelopment projects that disturb greater than 1 acre and
exceeds 12% built -upon area.
The Town has adopted the DWQ BMP Manual as its official BMP design guidance
document and every required structural BMP must be designed in accordance with the
manual. DWQ BMP supplement forms are also a required submittal with engineer
calculations. Operation and Maintenance (O&M) agreements are required on all
structural BMPs. Links to the BMP Manual and supplement forms as well as links to
downloadable O&M agreements are maintained on the stormwater page of the Town of
Apex website.
Upon installation of a structural BMP and submittal of certified as -built drawings by the
engineer, the Environmental Programs Manager or his designee inspects the BMP for
compliance with approved construction plans and issues a final approval letter once
satisfied. Town BMP as -built supplement forms are required with as -built submittals. The
forms are a checklist format, requiring the engineer to certify that all aspects of the
structural BMP were installed per approved construction drawings. These forms are
available for download on the Town of Apex website.
BMP inspection reports are required to be submitted by the BMP owner to the Town on
an annual basis beginning one year from the date of approval of certified BMP as -built
drawings. The reports must be sealed by a registered North Carolina engineer, landscape
architect, or land surveyor. Town of Apex stormwater staff complete the annual
inspections for Town -owned BMPs. Links to downloadable BMP inspection forms are
maintained on the stormwater page of the Town of Apex website. A spreadsheet log is
maintained by Town stormwater staff to track annual inspection due date compliance.
NOV letters and Civil Penalty Assessments are issued to non -compliant BMP owners as
necessary.
As of December 2015, there are 260 constructed structural stormwater BMPs in Town
that are inspected on an annual basis. Town stormwater staff maintain a comprehensive
database inventory of structural BMPs in Town as well as an updated map of the location
of all structural BMPs in Town.
