This landscape design and installation project was recognized in 2011 by receiving a National Award by PLANET (Professional Landcare Network). PLANET is an International association with over 3,800 members representing over 100,000 green industry professionals.
Shortly after purchasing their home, the owner of this property sought a professional landscape design/build company to renovate their existing landscape. Dennis’ 7 Dees Landscaping award winning design team designed the landscape based on the homeowner’s desires to have a sitting area with room for a BBQ and fire pit, a rose garden, a larger lawn area for their children to play, and a solution to reducing the traffic noise from a busy street.
The project started by installing a 150 foot long, 3 ½’ high, 2000-2500lb boulder rock wall along the backyard property line. This wall extended their existing lawn surface by an additional 1500 square feet. While excavating for the walls footing, Dennis’ 7 Dees Landscaping construction foreman discovered over 1/3 of the backyard was 100% fine sand backfill, 6 feet deep. While all soil types have the possibility to be built on, given all appropriate considerations are accounted for, in this case an evaluation needed to occur to ensure the installation methods would maximize the long term performance/safety of the wall, and extended lawn. We engaged the homeowner to explain to them the discovery of fine sand beneath the surface and to discuss options. The solution jointly agreed was to remove the fine sand impacting the walls footing and then mix the remaining sand with imported topsoil.
After the wall was completed, a terraced water feature was installed. The fall of the water from the three spillways has significantly reduced the street noise and has provided a focal point for the patio area. The design of the water feature included integrating it into the natural contour of the slope and into the rock retaining walls which were necessary around the west perimeter of the house. Prior to the installation of the water feature, large boulders needed to be removed and were reused on site. The final grade for the patio area around the water feature had to be lifted 18”. The original grade had the entire backyard draining toward the house and collecting where the new patio exists. A drainage system was installed to channel the water away from the house and safely to a drainage collection pond.
A terraced rose garden was installed following the nature contours of the landscape. The garden was planted with the homeowner’s favorite hybrid tea roses. Arbors were installed at each end of the rose garden and a pergola was installed over the newly installed circular paver patio. In reviewing the before and after pictures, notice the significance of adding vertical elements to this garden (pergola and arbors).
As the construction process continued, everyone involved with project came to realize that the previous owner of the property took short-cuts and installed many creative solutions when it came to irrigation, drainage, soil retention, and backfill material. While no homeowner desires to have any challenge buried beneath the landscape surface waiting to be unearthed during construction, this homeowner was grateful to have an experienced, knowledgeable team of professionals working with them to resolve the challenges while not taking their eye off the end result of delivering a beautiful landscape.

I have been a landscape designer my entire life. My first attempt at landscape design and installation was when I was 9 years old on my family’s farm in Eastern Oregon. Outside my parents’ dining room window were these two smelly, over-grown junipers. I persuaded my Dad to remove the junipers and allow me to install a small rock garden with plants. It was my first success! I continued to dabble in design while attending high school and college. In college, I received my degree in finance and economics from the University of Oregon, which led me to a career in finance and accounting in Hi-tech. Having international aspects to my job enabled me to travel to Europe and Asia. This experience exposed me to cultural and environmental diversity and enabled me to visit both public and private gardens. The travel was enriching and fueled my desire for a change from the corporate life style. Consequently, I took the plunge, turned in my resignation, and bravely went back to college where I obtained both an associate’s degree in Landscape Technology and a degree in Landscape Design. While attending college, I pursued and obtained an internship with Dennis’ 7 Dees Landscaping and served on the Board of Directors of the Association of Professional Landscape Designers-Oregon. Following graduation I become a designer at Dennis’ 7 Dees and was proud to serve as APLD-Oregon’s president. Most recently, I have been recognized by PLANET and received a national environmental improvement award. Throughout this incredible journey, I have had the unwavering support of my husband, family, and friends. I am truly grateful to be able to do what I love: Landscape Design.
