This publication discusses ways in which mosquitoes could become a problem for rainwater harvesting systems and provides solutions and preventative measures to protect cisterns, rain barrels, and other rainwater collection systems from becoming havens for mosquitoes.
A rainwater harvesting system captures stormwater runoff, often from a rooftop, and stores the water in a cistern for later use. In this guide for homeowners, the authors describe the components of a rainwater harvesting system and how they work together. Guidelines for choosing, sizing and installing the components are included.
Sediment basins are temporary stormwater pools that catch runoff so it can deposit some of its sediment. The typical outlet is either a rock dam or a perforated riser barrel, both of which allow water to leave the basin from all depths. One way to improve the sediment capture rate is to use an outlet that dewaters the basin from the top of the water column where the water is cleanest. This publication describes the Faircloth skimmer, flashboard risers and other outlet configurations that accomplish this goal.
This factsheet is designed to give a brief overview of natural and constructed wetlands and provide key information to help identify these wetlands and the functions they provide.
Stormwater wetlands perform well in reducing peak flows and pollutant removal when properly designed and constructed. These wetland construction guidelines are based on experience gained at more than 30 sites across North Carolina.
Construction sites of more than one acre are required to install systems to retain sediment produced onsite. This factsheet describes several chemical treatment options, including polyacrylamides (PAM), gypsum and alum, for reducing turbidity in impounded water.
This publication provides information about tidal flooding and reviews devices communities can use to modify existing infrastructure to minimize the effects of tidal floods.
This publication describes the evaluation of plant survival and vigor on 11 extensive green roofs in the Research Triangle region of North Carolina and provides plant selection guidelines for future green roof installations.
Golf courses provide a unique setting for wetlands that can be used to provide both an environmental benefit and an aesthetic amenity. The research-based recommendations in this publication are intended to help you optimize concepts and designs for your next project.
This publication discusses the practice of leasing estuarine waters on the North Carolina coast for shellfish mariculture. It covers how shellfish are grown in North Carolina, how shellfish leases work, what constitutes a shellfish growing area and shellfish harvest closure, and the process for reopening after a closure.
This factsheet provides a review of strategies for designing and maintaining stormwater facilities to limit mosquito populations.
An innovative Dune Infiltration System (DIS) has been developed to help prevent polluted stormwater from reaching the ocean. The goal of this factsheet is to introduce this technology to coastal towns that want to reduce the potential impact of stormwater discharge to their beaches.
These new design guidelines for stormwater wetlands focus on four design points: internal wetland zones, herbaceous plants that thrive in stormwater wetlands, a proper growing medium, and the importance of a flexible outlet structure and its construction.
This publication presents maintenance guidelines for stormwater wetlands and wet ponds, two stormwater practices that are being constructed across North Carolina. Stormwater management practices must be kept in proper working order to maintain their intended functions and aesthetic appeal.
As the use of permeable pavement increases in North Carolina, practitioners can look to research findings for guidance. Recent research in North Carolina and elsewhere has focused on four aspects: runoff reduction, clogging, long-term hydrology and water quality. This overview highlights research findings, discusses research implications, and provides direct links to the research.
This question and answer worksheet will help coastal homeowners focus on potential problems with the pollution and health risks of water protection practices and the effects on water sources from stormwater management. Car/truck wastes, yard/garden wastes, animal wastes, rain gardens and rainwater runoff are covered.
