15 Landscape Retaining Walls to Prevent Erosion

The landform has a major influence on driver perception of the highway and the surrounding landscape. The alignment and profile of the roadway and right-of-way are set early in the design process. These early decisions actually determine the overall character of the subsequent landform. Alignments that are set perpendicular to the natural lines of terrain will generally be the most problematic because they will require the greatest modification in grade.

Typically radical changes result in step cut slopes and deep fills. Depending on the terrain and the type of substrate, these deeper changes in landform can be visually objectionable and difficult to maintain. See Figures andAnchor: igrtop FigureRoad alignments which minimize deep cuts offer a flowing, gentle appearance. Deep cuts can be visually dominating, presenting a scarred appearance often difficult to re-vegetate. During the design process considerations should be given to the landform that will result from any particular alignment.

Primary considerations include:. Overall topics covered in this section are: landform manipulation for aesthetic purposes , designing for erosion prevention , limiting erosion potential , and ground surface protection for erosion control. Manipulation of the landform is a very effective tool for modifying the visual scale of roadside elements.

Landform manipulation will also add variety to the setting and reduce the sense of visual clutter common to urban centers and complex interchanges. Design solutions that employ landform modification are most cost effective when undertaken in concert with the horizontal and vertical alignment of the roadway.

Designers are encouraged to collaborate with landscape architects on projects where landform modifications can be used as part of the overall landscape and aesthetics design concept. Areas where landform modification should be considered as part of the overall solution include:. Large interchanges are sometimes visually confusing as a result of numerous bridge supports.

When approaching the interchange this may appear as a forest of concrete columns that have no pattern. These large highway interchanges frequently provide sufficient space to generate significant grade changes that provide a gentle contrast to a rigid architectural scene. Skillful manipulation of landform can help to reduce the visual scale and bring a better sense of visual order to the interchange. Landform modifications in interchanges can reduce the apparent scale of the structure and make landscapes more visible to overhead lanes.

Noise walls, because of their length and height, may be visually overpowering in terms of relative scale. To be effective the walls often must be higher than the buildings they are designed to protect. Where possible, use landform modifications or plant material to gain this elevation difference. This technique minimizes the visual dominance of the walls and blends the wall into the landscape.

Where space and drainage patterns allow, berms may reduce or prevent median crossings and reduce headlight glare. Careful consideration should be given to the cross section to ensure driver recovery, mowing access, and drainage.

No berms should be placed within the sight triangles at intersections or at crossovers on multi-lane divided highways. Roadway embankments often form large physical landmarks so their aesthetic character can have a significant impact on the surrounding community.

Excessively steep and abrupt embankment slopes do not blend well visually with adjoining landscapes, are difficult to maintain, may erode easily, and may limit or prevent the use of other landscape enhancements.

Many visual problems associated with embankments are related to the degree of difficulty in maintaining vegetation on steep slopes, near or between barrier devices, in inaccessible areas close to structures, signs, or luminaires. To reduce these problems, consider the following practices:.

Grass under guard fences is a continuous maintenance problem, requiring mechanical trimming or herbicide control. Concrete paving under guard fences is effective at vegetation control but may be difficult to replace if damaged. Open holes for posts allow replacement in case of damage but are susceptible to weed invasion.

Patterned concrete and color are options to add visual appeal under guard fences. Concrete mow-strips are effective and recommended for reducing maintenance and improving appearance. Weedy vegetation against structures tends to make the entire area appear untidy and trashy. Erosion of the ground surfaces in the roadway threatens the stability of the pavement and structures, increases costs for cleaning of drainage structures, and contributes to siltation and turbidity of nearby streams and lakes.

The costs associated with the control and repair of erosive surfaces can be significant and sometimes directly impact driver safety. Many erosion problems can be prevented by fitting the roadway alignment to the terrain and keeping slopes as flat as possible. Desirable cross sectional properties of a highway are as follows:. The areas most susceptible to erosion are slopes and greater associated with embankments and drainage channels.

Embankments often receive concentrated runoff from pavement surfaces that, depending on soil and slope conditions, may lead to significant erosion problems. Sheet flows on slopes are the primary mechanism for transporting soil down the face of the slope. Erosion can be limited by intercepting any surface flow at the top of the slope and conveying it in a suitable channel to the base of the slope. Concentrated flows should be intercepted at the top of the slope in diversion channels and conveyed in turf reinforced channels to the bottom of the slope.

Turf reinforced channels use a permanent geosynthetic fabric to reinforce the channel and prevent scour of the channel surface. Paved gutters on the face of embankment slopes are not recommended. Paved channels interfere with mowing activities and frequently break up as embankments settle.

Designers can limit erosion potential through the use of approaches such as:. Many visual problems associated with embankments are related to the degree of difficulty in maintaining vegetation on steep slopes, near structures or between barrier devices, or in inaccessible areas close to structures, signs, or luminaires.

The following practices help prevent potential problems in these areas. Solid-surface paving materials such as concrete and asphalt have been successfully used in these areas. Asphalt paving should incorporate concrete edging in turf areas to protect it from deterioration. Textures and colors may be added to these materials to add variety and interest. These materials are preferred over loose aggregates and pavers since the latter are easily invaded by weeds.

See Figures throughConcrete is the preferred material for use as mow-strips along beds and walls. Asphalt is not suited since its edges are easily invaded by weeds and grass and the edges are susceptible to damage by mowing equipment unless a concrete edge is included. Drainage channels are important components of the roadway and are detailed in the Hydraulic Design Manual look for it to be available online in the near future. In addition to hydraulic design, channels should be designed to prevent long-term soil erosion.

Design characteristics that will prevent or reduce erosion are as follows:. Narrow, steep-sided channels are susceptible to erosion by high water-flow velocities making permanent vegetation difficult to establish. In addition, weedy growth in narrow channels is difficult to remove mechanically, requiring increased use of herbicides. As highways and interchanges increase in size, larger land areas are incorporated within the right-of-way.

These areas help meet environmental requirements and can add to the aesthetic quality of the highway and the surrounding landscape. Water detention basins and ponds are used to provide flood control and remove silt and contaminants from highway runoff to protect downstream water bodies.

Properly designed ponds rely on the bio-filtration and particulate-capture capabilities of the soil and vegetation. The design of these structures begins with clearly defined goals for the hydrological needs for water control integrated with a thorough understanding of vegetation and ecosystem properties and their management.

Allow adequate recovery areas around ponds and basins. Use native vegetation at basin edges to provide a natural appearance.

The primary material used for erosion control on the roadside and in drainage channels is vegetation. However, prior to establishing permanent vegetative cover it is usually necessary to protect the soil surface from immediate erosion.

There are a variety of natural and synthetic materials available for temporary erosion control. There are two primary considerations in selecting an appropriate temporary erosion control measure: soil type and slope.

Research shows that soils with greater than 17 percent fine sand or silt particles are highly erosive. Soils with less than 17 percent sand or clay particles can be considered cohesive soils or clays. As the degree of slope increases, the potential for sheet erosion increases.

Sandy soils can be protected with hydraulically applied mulch or straw or compost on slopes up to 7 percentAbove 7 percent an approved soil retention blanket or erosion control compost should be considered. Cohesive clays can be protected with mulches on slopes up to 20 percentAbove 20 percent, riprap should be considered. The primary function of mulch is to maintain moisture in the soil and foster seed germination and plant development.

There are three types of mulch used for erosion control:. Straw and Hay Mulch. Straw and hay mulch are used as surface covers in conjunction with some type of tacking agent tackifier. The tackifier helps form a uniform mat and prevents migration of the material down the hill. Straw can also be crimped to help prevent material loss or migration. Cellulose Fiber Mulches. Cellulose fiber mulches are hydraulically applied. Cellulose mulches may be applied with the seed mix and a tacking agent to form a more consolidated mat on the surface.

TxDOT maintains a list of approved cellulose mulch materials. Depending on the soil type, hydraulically applied mulches can be used on slopes up toIf the soil is very sandy cellulose mulches would not be recommended on slopes overCompost may be blended to make compost manufactured topsoil in flat areas.

Slopes up to should utilize Erosion Control Compost.


9 Inexpensive Ways You Can Prevent Erosion

Most people associate the term soil erosion with vast dust storms blowing up the topsoil and floods sweeping away the topsoil downstream during the summer and spring months. Only a few people realize that the cold winter months may also come with elements that contribute to soil erosion. Like in the spring and summer months, soil erosion can be a big problem during the winter months. If you are a landscape owner, knowing the cause of soil erosion during the cold months can greatly assist you to plan on how to control erosion so as to minimize the effects of losing all your topsoil. Winter winds can blow away unprotected topsoil. During the cold months, soil can become loose due to sudden and extreme changes in temperature. Once the strong winter winds come along, the loose topsoil goes along with them.

While these long-lived shrubs have a reputation of being somewhat fussy, newer cultivars bred for disease-resistance and vigor have made growing roses easy for even novice gardeners. A rose garden can be as simple as a single rose specimen interspersed with a few other plants. It can be as elaborate as a formal landscape embellished with hardscaping, arbors, seating, and statuary. Even smaller spaces can accommodate roses in containers, raised beds, or narrow side yards. Here are the basics of rose garden design, along with some ideas to get you started. Make sure the site gets at least hours of sun a day and has good air circulation to help prevent disease. Gather ideas from books and online sources for inspiration. Include pathways for easy access. Beds should be small enough to allow for pruning and other maintenance chores.

Landscaping a garden on a hillside or as it connects to a hillside can be a huge challenge; without the right support, the integrity of the hillside will collapse. Below are a few ideas for hill stabilization. There are many ways to shore up a hillside to prevent soil erosion. Water and gravity push soil down the hill.

When designing a residential landscape, the most important step is to put a plan on paper.

How to Place Rocks On A Slope To Stop Erosion

Erosion from rainstorms, flooding, and wind can ruin landscaping, disrupt local sewer systems and stormwater management, and even destabilize a site threatening the stability of homes and other structures. Builders should plan for and employ short-term erosion practices during construction and long-term erosion practices for the long-term protection and safety of the home, especially at sloped sites in areas prone to heavy rains, which may be subject to erosion, displacement of topsoil, and mudslides, and at sites located on or near waterways which may be subject to storm-related flooding. There are several erosion-resistance measures builders can employ. Discussed here are practices to employ during construction including the use of mulch and erosion control products and long-term measures including vegetated slopes Figure 1 , terracing, riprap and bio alternatives, retaining walls, and barriers, and special concerns for coastal construction. When siting a home, designers should take into account the long-term risks to the location including erosion and mudslide risks for homes located on slopes. Erosion control is often needed on site during construction when vegetation on site is disturbed leaving soil exposed to wind and rain.
