Image
A drywell, shown here used for downspout catchment, can also be used to receive water from a French drain.
Image
A French drain contains a perforated drain pipe wrapped in rock and landscape fabric.
Image
A plastic fiber drainage mat rainscreen provides uniform support for the siding and allows moisture to flow horizontally and diagonally in addition to vertically.
Image
Image
Image
A swale and berm can be installed together across a slope to slow the downhill flow of water.
Image
Adding planted terraces to a sloped yard can slow down runoff and reduce erosion
Image
Image
Image
An engineered bioswale uses perforated pipe laid in rock and landscape fabric at the bottom of a vegetated trench to direct water away from a site.
Image
Image
Berms are compacted earth or gravel ridges that slow the flow of water from rain, riverine flooding, or storm surges in coastal areas.
Image
Berms, swales, bioswales, ridges, and vegetation all help to control rainwater runoff on residential sites.
Image
Bioswales or rain gardens filter storm water through vegetation and rock and sand substrate layers.

Image
Comprehensive water management features include a capillary break (≥ 6-mil polyethylene sheeting) at all crawlspace floors

Image
Dune erosion caused by the combination of a hurricane and a nor’easter in Ocean City, New Jersey
Image
Image
Image
Image
Good water management practices like sloping grade away from house, and installing gutters, perimeter drain pipe, a capillary break, and free-draining soils or drainage mat protect the foundation from water saturation.
Image
Image
House wrap is sealed at all seams and overlaps flashing to serve as a continuous drainage plane over the exterior walls.
Image
Image
Install all layers of the drainage plane to overlap, not underlap, to direct bulk water down and out of the wall.
Image
Install furring strips over house wrap to provide a rainscreen behind wood siding.
Image
Image
Image
Installation of an erosion control blanket to minimize soil loss on sloped ground that has no established vegetation
Image
Image
Image
Image
Image
Planting deep-rooted native grasses and shrubs on the banks of shorelines can help reduce the effects of erosion on sandy slopes
Image
Image
Plywood or OSB panels are a cost-effective way to protect windows from wind-borne debris.
Image
Image
Porous surfaces like pavers allow water to pass through and percolate slowly into the soil
Image
Image
Repair leaks and cracks, and cover holes in foundation floors and walls to minimize water and vapor entry.
Image
Retaining walls can prevent erosion and landslides and maintain access to critical infrastructure
Image
Retention walls, permeable pavement, french drains, drywells, and ditches all help to divert, collect, and manage the flow of stormwater on a site.
Image
Ridges can be constructed and planted to slow the downward flow of water and stabilize slopes.
Image
Right – The ties are bent at a 90 degree angle at the nail head and embedded into the mortar joint at least 1.5 inches.
Image
Right – The ties are bent at a 90 degree angle at the nail head and embedded into the mortar joint at least 1.5 inches.
Image
Image
Right – Furring strips provide a drainage and ventilation gap between the siding and the cork insulation.
Image
Right – Furring strips provide a drainage gap between the rigid foam and the siding.
Image
Image
Right – The building felt is installed on all exterior walls and provides a complete drainage system
Image
Right – The drain slopes away from the foundation and terminates at the proper distance
Image
Image
Right – The ridge flashing is secured with two rows of fasteners on each side of the ridge line
Image
Right – The rigid insulation covers all exterior walls and all seams are taped to provide a complete drainage system
Image
Right – The water-resistant barrier covers the entire house and the seams are taped to provide a complete drainage system
Image
Right – This exterior door is installed to swing out and has storm protection shutters.
Image
Right – This low-slope roof and parapet assembly has continuity of both the air and water barriers
Image
Right – This metal panel window shutter is installed in a track permanently mounted above and below the window frame and is secured with wing nuts to studs mounted on the track.
Image
Right – This swale has sloped sides with appropriate vegetation to filter rainwater.
Image
Rigid foam insulation can serve as the drainage plane when all seams are taped. Furring strips provide an air gap behind the cladding.
Image
Image
Image
Shrubs, trees, and herbs create a tight network of roots and stems that bind the soil and slow the flow of water down hillsides.
Image
Soil types include sand, silt, and clay- the more sand, the more quickly the soil drains.
Image
Swales are trapezoidal channels dug to receive storm-water overflow, with specific vegetation planted to improve aesthetics, filter stormwater runoff, and prevent erosion.
Image
Swales are troughs that collect site stormwater and filter it with vegetation, soil, and gravel layers.
Image
Image
The “down” and “out” approach to flashing – metal flashing directs water down and out of building assemblies
Image
Image
Image
Image
The sheathing has rotted because there was not a sufficient drainage gap behind the stucco cladding
Image
This double French drain provides drainage for a significant volume of storm water.
Image
This home was designed with continuous roof vents and few roof penetrations, allowing more room for the solar shingles that integrate with the asphalt shingles installed to meet IBHS Fortified Roof criteria for increased resistance to high winds and rain
Image
This roof was constructed to meet the IBHS Fortified Roof standard by sealing the decking seams with flashing tape, installing synthetic roof underlayment secured with metal drip edge and nailed every six inches, and using self-adhered starter shingles.
Image
This swale and berm slow the flow of stormwater across a site to minimize erosion.
Image
Image
With fiber cement siding, face nail rather than blind nail where the design wind speed is ≥100 mph.
Image
With fiber cement siding, place blind nails 3/4 to 1 inch from top edge and > 3/8 inch in from butt ends.
Image
Image
Wood siding installation details to improve resistance to wind-driven rain at corners.
Image
Wrong - The window lying on the ground was protected by a shutter but the shutter was attached to the window frame, rather than directly to the wall framing.
Image
Wrong - Utility trim was substituted for the starter strip and the bottom lock was cut off this vinyl siding so the siding pulled loose under wind pressure.
Image
Wrong – Drain pipe has been cut and foundation penetration has not been properly sealed
Image
Image
Wrong – For proper detailing of vinyl around windows and other obstacles, use utility trim, punch snaplocks into siding, and do not overlap directly beneath a window.
Image
Wrong – Known as a Hugel Swale, organic matter like sticks and leaves break down into compost and fill the swale full. This limits the swale’s ability to filter rainwater.
Image
Wrong – Misalignment of the tie reduces the embedment and enables the brick veneer to be pulled away.
Image
Wrong – The clips holding these metal roofing panels were set too far from the roof eave (above red line) and the panels lifted in strong winds
Image
Image
Image
Wrong – The ridge flashing fasteners were placed too far apart and did not adequately hold the flashing in place
Image
Wrong – The rigid sheathing seams are not taped and the gaps could cause moisture problems
Image
Wrong – The underside of the first course of siding extends beyond the underlying sheathing leaving it vulnerable being pulled off by pressure from high winds.
Image
Wrong – The vinyl siding at this gable was installed over rigid foam instead of wood sheathing and neither had the structural strength to resist hurricane wind pressures.
