Creative Traffic Control

bollards, landscape designIf you need to control or restrict vehicular traffic in an unobtrusive way, bollards do the job. Spacing can be done to permit small, special-purpose vehicles inside while keeping sedans and trucks out. Four feet is a good height for a bollard, but they can be lower if you only want to deflect tires. Remember, anything over seventeen inches can be in conflict with vehicle bumper overhang. Because bollards are relatively small, they can be made to be removable from ground sockets and relocated as needs change. They can also be retractable, something necessary to allow first-responder access in emergencies.

Even though bollards are relatively unobtrusive visually, they can be decorative. You can incorporate lighting. They can serve more than one purpose. The design can look like the original mooring bollards for ships. Boats are a design inspiration for many, but you can dream up lots of innovative and imaginative options.

Outdoor Wedding or Event Venues

“Make Me Wanna Shout!*”

outdoor wedding venue design

Lots of weddings take place outdoors. If you are designing an outdoor wedding landscape site, think about providing a space which can suit different personalities. Outdoor wedding and event spaces are great opportunities to allow your landscape design imagination to soar. These are fantasy outdoor spaces. Have fun designing them! Outdoor events provide room to add large, temporary props which can be secured by simply putting stakes in the ground. An outdoor wedding requires good planning and many safety net, in case the weather gets bad.

Outdoor wedding landscapes should consider the comfort and safety of the guests. Provide a solid parking area for your outdoor wedding venue. Be sure to provide wheelchair accessible seating and circulation. Provide a place for refuge from inclement weather or brutal heat. A pavilion is a nice addition and can be decorated and themed to compliment the other floral designs. Provide plenty of seating and tables. Do all you can to make the guests happy they came and reluctant to leave.

Landscape Design

You can learn the hard way, through years of successes and failures, or you can get mentoring tips from someone else who has gone through the process for you.  The landscape industry is changing rapidly, and many of those who have become experts with time-tested experience are leaving.

Not only that, the professions that provide expertise have become highly specialized, with no single firm being able to pull together all the essential elements of a landscape plan that delights and works well, incorporating good horticultural, landscape design, engineering, and maintenance knowledge into a really good landscape plan.  Outdoor living spaces that are a pleasure to experience are becoming all too rare.  When you are lucky enough to visit one, there is a quiet inside voice asking, “Why can’t I do something like this at home?” Outdoor living spaces that are a pleasure to experience are becoming all too rare.

It is possible to create beautful landscapes. Here’s a link soon to the soon-to-be published draft version 0.0 of a new Advanced Guide to Landscape Design, based on years of experience working with the pros and evaluation of thousands of landscape projects.  

Bike Paths

Share the Road

A bike path is a linear park. Restricted access sometimes makes sense, but usually, the more people and activity near a path, the safer it is. Lighting can also add to the public safety of the path. Communities need alternate ways of getting from one place to another, rather than depending on automobiles. A safe, excellent path system is a draw for economic development.

Complete screening with fences or walls of a bike path can create new, big problems that can make it dangerous to use. Adding vegetative screening for a bike or multi-use path can add safety issues, too. Try to keep paths open to visual checks from passing cars and police patrols.

A local government entity or homeowner’s association should budget for bike path maintenance, with regular reports of pavement status and issues as a part of every public meeting.

Landscaping Steep Slopes

Holding Your Ground

landscaping steep slopesSlope rations for planted areas are a critical consideration for the establishment of plant material. For planting, a slope ratio of one foot of drop for every four feet of horizontal distance, called “four-to-one” (4:1) slope, or flatter, is best. Most of the time, the area beyond the graded platform for hardscape structures is steeper than that. Here are some general rules for deciding what to do with steep slopes.

Any slope steeper than “three-to-one” (3:1), is difficult or dangerous to mow. Trying to establish turf grass on slopes so steep is difficult, too. For steeper slopes, use vigorous ground covers, or a mixture of vigorous shrubs and native grasses to hold the soil. Another option is to use large masses of Juniper shrubs. They have long, low, spreading forms that do a good job of holding slopes on commercial properties, where professional maintenance crews can use a custom spray program to reduce typical Juniper pests and special pruning techniques to keep their spikes dense and weed-free.

Early March is the Time for Topdressing

The Perfect Filler

Just before your turf grass begins to green up for a new season, topdress low spots and depressions in the lawn with cow manure or sand mixed with cow manure. The gentle fertilizer provides just the right amount of encouragement for grass to grow and fill in bare spots, too. Layer on as much as possible without covering the tips of the new grass blades. 


Retaining Walls

Safety is the Key Design Element

Retaining walls must hold steep slopes. The only reason you don’t see them used more often as a feature is because they are so expensive.

Retaining walls can be both a beautiful and functional part of a landscape. Gabion walls are boulders contained in wire grids. They can be used in inexpensive ribbons or mattress shapes to provide slope stability in difficult situations. They can be made more attractive with live stakes or other vegetation inserted between the openings in the walls. Concrete retaining walls are massive slabs of gray, but they can be made more attractive by incorporating attachment ties along the façade for adding a decorative face. Textured forms can build in interesting surfaces on concrete wall surfaces. Modular units are often used to build attractive and easy-to-construct terraces. 

Retaining walls can be dangerous. If a wall is over four feet tall, a landscape architect must call in a civil engineer for design assistance. Walls can fail, and when they do, they can fail in a large way, posing a hazard to people and property.

Gravity walls are massive structures that use large stone units, battered back about one-half inch each top course to form a slanted wall. They hold back soil through sheer weight. Most gravity walls are low. Because it is difficult to gauge how well they can do their job, the chance of damage during unusual storm events is high. A “dead man” can be added to hold the wall in place, by keying perpendicularly to the hillside. Railroad tie walls use T’s made from additional ties and secured to the wall to do this.

Larger retaining walls are reinforced concrete with rods or interlocking keys. Additional geosynthetic fabric is often used every few feet, woven into the layers of backfill to add strength. Modular units can vary in quality, so shop carefully and choose wisely. Good pieces typically weigh over fifty-five pounds each.

How Different Plant Shapes Create Excitement in Your Landscape Design

Sameness Equals Boring

vary plant shapes for exciting landscape design

Different plant shapes create excitement in your landscape design. Sameness equals boring, so mix up the plant shapes and textures. Ornamental plants come in all shapes. Thank goodness for that! You need the contrast of spikes with mounds and the juxtaposition of flat forms with pendulous cascades. Before you send out a finished landscape plan for bid, do a quick review of the plant material chosen to be sure you provide the right amount of contrasting shapes—not too busy, and not too plain.

A landscape is a lot like a giant, outdoor floral arrangement. Create some drama with different shapes. A formal, squared-off hedge looks better against a carefully-shaped evergreen mound at the end of the row. An amorphous tall shrub becomes a star growing above a mass of weeping facer plants falling over their shared planter. A sharply-spiked focal point is grounded with a low, flat ground cover.

Use the natural shapes of plant material to reinforce the structural design of the garden. Tall, columnar conifers can pierce the vertical space to indicate stopping points for circulation. Undulation of eye-level, layered masses can lead garden visitors along a path. Spreading limbs can soften the hard lines of pavement or walls.

Remember, plants in real life don’t look like the ones in kindergarten pictures—simple balls of green. The varieties of shape and form are plenty, and provide lots of choices for the accomplished landscape designer.
