Need a stormwater management plan for building or resource consent in Northland? Gumboots Consulting Engineers prepares stormwater management plans, drainage design, and flood risk assessments accepted by FNDC, NRC, and Whangarei District Council — for Kerikeri, Whangarei, Paihia, and across the Far North.
A stormwater management plan (SMP) is a council consent document that shows how stormwater from your site will be managed — ensuring it doesn't create flooding, erosion, or contamination downstream. It is required for most new builds and developments in Northland.
Most building consents in FNDC and WDC require a stormwater management plan showing roof drainage, driveway runoff, and site drainage to a legal point of discharge.
Subdivisions require a comprehensive SMP addressing stormwater infrastructure for all lots, including overland flow paths, detention, and discharge to waterways or council systems.
Large impervious areas like car parks and industrial yards generate significant stormwater. SMPs for commercial sites include treatment and detention design to meet NRC discharge rules.
Properties near streams, rivers, or areas with a history of flooding need a flood risk assessment as part of their SMP — required by NRC and most building consents in these areas.
Comprehensive SMPs for building and resource consent covering site drainage, roof and driveway runoff, overland flow paths, and discharge to a legal point. Accepted by FNDC, NRC, and WDC.
Engineering design for stormwater drainage systems — pipe sizing, soakage systems, swales, and detention ponds. We design practical systems that work in Northland's rainfall environment.
Assessment of flood risk for sites near waterways or in low-lying areas. Required by NRC and councils for building consents and resource consents on flood-prone land in Northland.
ESCPs for earthworks consent — required by NRC for any significant earthworks in Northland. We prepare practical ESCPs that satisfy NRC's requirements and work on site. See our full erosion control services.
