SWCPS – Stormwater Construction Plan Submittal Checklist
Location of stormwater management structures should meet setback requirements from all wastewater
system components in accordance with Regulations Governing Wastewater Treatment and Dispersal
Systems in Wake County.
RESIDENTIAL ONLY Perpetuity statement
Maximum Impervious Area Square Footage on each Individual Lot will be Stringently Enforced with no
Exceptions into Perpetuity. Plans approved with a maximum impervious surface of (insert) SF per lot.
Standards and Requirements
By marking items with an “X”, applicant acknowledges potential standards to be applied to the proposed development.
Wake County UDO Article 8 – Subdivision Design and Improvements
Article 8-37 Streams or Drainageways - Easements for streams or drainageways must be provided and must
follow the existing course of such streams or drainageways. Easements for drainage of surface waters from 4
lots or less may cross lots only if the Planning Board or Planning Director determines that such location will not
pose a hazard to persons or property.
Article 8-42 Lakes and Dams - If a lake is proposed to be constructed or retained within a subdivision, the lake
and its dam must be constructed or structurally upgraded to accommodate the runoff from a 24-hour, 100-year
• Runoff computations must use [SCS] methods or other acceptable engineering standards
• Any lake with a dam that is 25 feet in height or more, or that an impoundment capacity of 50 acre feet
or more must obtain State agency approval in accordance with Article 21, Chapter 143 of the North
Carolina General Statutes.
Article 8-43 Standards - All subdivisions within the zoning districts R-40W, R-80W and overlay districts WSO-
2NC, WSO-3CA, WSO-3NC and WSO-4P must be designed and constructed so that all development directly
associated with the subdivision (e.g., roads, utilities, grading, drainage facilities) and all subsequent
development (e.g., buildings, driveways, yards, on-site utilities, grading, drainage facilities) on the subdivision’s
lots and other parcels:
• minimizes impervious or partially pervious surface coverage;
• diffuses the flow of stormwater runoff, encourages sheet flow and avoids concentrated discharge of
stormwater into surface waters;
• incorporates Best Management Practices (BMPs) to minimize adverse water quality impacts;
• transports stormwater runoff from the development by vegetated conveyances; and
• avoids disturbance of vegetation within water supply watershed buffers
Wake County UDO Article 9 - Stormwater Management Requirements
See Wake County’s Stormwater Manual: Submittal and Design Guidance
Stormwater Review Required - All residential subdivision development must submit a plan to comply with
Article 9. Minor subdivisions have the option of limiting impervious to 15%. Office, institutional, commercial or
industrial development that disturbs greater than ½ acre is required to comply with the stormwater
management regulations of Article 9.
Stormwater Permit – is required for all development and redevelopment unless exempt pursuant to the UDO. A
permit may only be issued subsequent to a properly submitted, reviewed and approved stormwater
management plan and permit application. [Article 9] Note: A permit may not be required if there are no post-
construction requirements (i.e. BMPs).
