Project Highlight: Gateway Village General Improvement District

The city of Denver uses various improvement districts to construct, improve, and maintain neighborhood and commercial areas. One such General Improvement District (GID) has been created for a section in the large Northeast Denver neighborhood of Montbello, and is called the Gateway General Improvement District (GID). We are happy to have been contracted by The Gateway GID in hopes of helping to revitalize the neighborhood by updating the current landscape and introducing more drought-tolerant, colorful plant varieties for areas around the neighborhood. These areas include street tree lawns, detention ponds, a large drainage channel, and the monument sign area. The nearby green space study, as seen below, analyzes the nearby park spaces, most of which are too far from most homes in the GID to be within walking distance. This posed a great opportunity for us to not only revitalize the outdated and rundown landscape around the neighborhood, but to help create community green spaces, by utilizing the barren and unused detention ponds.

 

 

The streetscapes throughout the neighborhood contain endless amounts of water-guzzling bluegrass, along with landscape beds overflowing, overgrown junipers and bare spots where other shrubs have died. Our design has these streetscapes being updated to replace the existing sod and desolate landscape beds with drought tolerant shrub varieties and rock mulch to reduce irrigation requirements while also providing a cohesive and interesting landscape year-round.

 

 

In the detention ponds around the neighborhood, our landscape designs aim to incorporate a more usable lawn space with pedestrian access, as well as add colorful, xeric varieties of shrubs and trees to the perimeter of the pond at street level to increase passerby interest and beautify the area. These ponds present a huge opportunity to provide nearby families with accessible parks. Two of the detention ponds are located directly across the street from two elementary schools in the neighborhood. These particular ponds presented us with a huge opportunity to not only turn these unused areas into park spaces, but educational learning landscapes as well.

 

We collaborated with Denver Public Schools to incorporate interesting educational elements and various ecosystems that will coincide with lesson plans made by teachers. Ecosystems include a wetland ecosystem where students can do water testing and observe the various birds and insects, as well as a dryland ecosystem featuring drought tolerant, native Colorado plant varieties. Other educational elements include a pollinator garden that will feature colorful shrubs and perennials attractive to bees and butterflies, demonstrating the importance of pollinators.

 

 

A boulder garden can also be found in the new educational landscape designs with an array of boulders showcasing Colorado’s diverse geology. To offer a more structured outdoor classroom, we have designed the detention pond slopes to incorporate an amphitheater with siloam stone slab seating. To top it off, children can follow a concrete pathway painted with the planets from our solar system, down into one of the amphitheaters.

 

 

With the Gateway Village General Improvement District being large in scope, we hope to reach a vast majority of the community at and positively impact them with all of these desired improvements.

Project Highlight: Multi-family Community Pool Area Renovations

As the Denver metro area continues to grow in population and our real estate market experiences growing pains, many existing multi-family housing properties have become golden opportunities for renovation and renewal. Here at Outdoor Design Group, we have recently been contracted by several clients to not only bring a fresh look to these common area landscapes, but to incorporate various outdoor amenities and create an extension of usable outdoor living space.

A couple of notable landscape renovations we have been fortunate enough to design were two properties owned by a California real estate company. They appointed us to help redesign the landscape to compliment their building renovations, giving each outdated property a much needed face lift.

The first property, located in Federal Heights, Colorado, is a large complex comprising of several units and a separate leasing and fitness center building. The leasing and fitness center was to be completely remodeled, and the entrance reconfigured. Our landscape design incorporates hardscaping like retaining walls and unique paving surfaces that compliment the updated architecture, and guide users toward the new entrance. Additionally, the numerous low-water plant species were selected and placed throughout the beds to create interest with their distinctive structural forms and colorful habits, which molded with the new modern style the client was striving toward.

 

A 3D rendering of the modern style entrance landscape helped our client to better visualize the space.

 

Attached to the East side of the leasing and fitness center is the community pool area, which was also overdue for a fresh look. In our design, the existing pool was to remain as is, but the surrounding pool deck was modified to be larger with a sleek, colored pool deck coating. A striking modern style gas fireplace was incorporated at the west end and amenities like shade structures, grilling stations, LED landscape lighting and picnic tables provide the finishing touches on the new design.

The second multi-family property Outdoor Design Group provided landscape design services for is located in Lakewood, Colorado. Its existing pool area was drab and outdated with no extra amenities. Our design integrated a large turf area for games, outdoor kitchen with a pergola, and a gas fire pit, all alongside a brand new decked out pool house designed by a Phoenix based architecture firm. The large bi-fold doors were designed to fully open toward the pool, and create effortless indoor/outdoor living. We welcomed the opportunity to design a space that allowed us to really visualize and get excited about how the space would be used. Additionally, the low-water use plantings surrounding the pool were chosen to provide year-round interest as well as screening from the nearby road.

Construction on these projects is currently underway, and we can’t wait to see the final results! Multi-family housing projects, both new development and site renovations are a hot commodity here in Denver, and the demand is ever increasing. We love being involved on projects like these, and we look forward to more to come.

Dog Tuff African Dogtooth Grass: The Best Turf Grass for Hot & Dry Sites

Do you love having a lush lawn, but hate the idea of wasting water? Do you have dogs who leave unsightly dead spots in your lawn where they’ve urinated? If you answered yes to either of these questions, then Dog Tuff African Dogtooth Grass (Cynodon ‘PWIN04S’) may be the best choice of turf grass for you. Dog Tuff is drought tolerant, resistant to dog urine, thrives is full hot sun, and is soft underfoot. Dog Tuff is a sterile variety of Bermuda grass, so it won’t spread via seeds. Dog Tuff grass was developed by respected Colorado horticulturalist Kelly Grummons. Kelly is working with High Country Gardens, and Plant Select to market this product. Watch this Plant Select video to see Kelly discussing this wonderful product:

 

Kelly has been working on bringing Dog Tuff to market for over ten years. The original parentage for this grass is native to South Africa, where a lush patch of it was found on a ranch. Dog Tuff is a “warm-season” grass, so it does not green up as early as blue grass. However, as Kelly mentions in the video, Dog Tuff needs only a fraction of the water to survive as compared to bluegrass. Dog Tuff grass will grow in many soil types, but it does need full sun (6 or more hours of direct sun). Dog Tuff is rated hardy to USDA zone 5.

We recently provided design services for a public park in Arvada, Colorado, where we incorporated Dog Tuff grass into an area the park. It was planted last year and is doing well. We are excited to have this as part of a park where people can visit and see the grass in person.

If you are planning a new lawn, or if you are thinking about replacing your current lawn with a more drought tolerant type of grass, you should consider incorporating Dog Tuff African Dogtooth grass in your home landscape.

The 4 Most Dangerous Trees for Colorado?

As gardeners in Colorado may well know, our climate and altitude make for challenging growing conditions. This doesn’t mean we are completely immune from invasive exotic plants making an unwelcome home here. We do not have the burden that gardeners in wetter and warmer states may have at stopping the spread of invasive plants, but there are a few species you should be aware of so you can help stop these unwanted guests from gaining a foothold in our landscapes.

Why be concerned about invasive plants? They crowd out native plants, propagate uncontrollably, and may reduce forage for wildlife. Some may have a negative impact on your garden plants. And research suggests that some invasive species may pose dangers to humans through the increased risk of flooding due to damaged waterways, or increased fire danger.

The two worst invasive woody plants for Colorado and the surrounding region are the Russian Olive and the Tamarisk. Russian Olive (Elaeagnus angustifolia), is native to western and central Asia. It was introduced into North America in the latter part of the 1800’s. It is not related to true olive plants (Olea europaea) but its fruit is edible but not very palatable for human consumption. It out competes native plants because its seeds are irresistible to birds which spread the seeds far and wide. The seeds have a low mortality rate, germinate readily in poor soil (it can fix its own nitrogen in its roots), reach maturity quickly and thus outcompete native plants. In Colorado, they often begin setting a foothold in riparian areas, and then spread from there.

Tamarisk (Tamarix ramosissima), which is more of a shrub than a tree, similarly starts its spread in the riparian areas of the Colorado and other southwestern states. It has been such a successful invader of wet areas, that it has overtaken huge sections of the rivers of the southwest. However, it is not as tolerant of cold temperatures as is Russian Olive, which restricts its spread to the warmer, lower elevations of the southwest. Tamarisk is tolerant of many soil types, and thrives in full sun. One of the concerns about Tamarisk’s effect on native landscapes is how they out compete native vegetation, altering the nutrient cycles of riparian areas. They also consume large amounts of water, and secrete large amounts of salt, both items further slowing the success of nearby native plants. A massive amount of resources and manpower are being directed at the fight to stop the spread of this plant through the wildlands of the desert southwest.

…the Siberian Elm is “one of, if not the, world’s worst trees…a poor ornamental that does not deserve to be planted anywhere”.

 

Closer to Denver and the urban areas of Colorado’s front range, there are two trees that are common pests. These are the Siberian Elm (Ulmus pumila), and the Tree of Heaven (Ailanthus altissima). Both of these trees release a profuse amount of seeds, and these seeds are very adept at sprouting in disturbed areas. They proliferate along transportation corridors and abandoned lots. Both trees prefer full sun, but Ailanthus can tolerate some shade allowing it to invade some mature native forests.

Although not directly related, Ailanthus trees (a.k.a. Tree of Heaven) are often mistaken as sumacs. In springtime they produce many flowers that have a foul odor which some say is similar to cat urine. It rapidly out competes other tree species, releasing an allelopathic chemical which inhibits the growth of other plants. Some researchers have extracted this chemical from Ailanthus trees, successfully using it as an herbicide. Not only is this tree toxic to other plants, there have been anecdotal reports of it being slightly toxic to humans and livestock. Ailanthus trees can grow quite rapidly, leading to weak, unstable branches.

Siberian Elms also have structural problems, with many weak or dead branches that can break off in heavy wind. Siberian elms have a short dormancy period which leads to early flowering in spring, and late leaf drop in fall. In Colorado that means they can become dangerously loaded with wet snow in our common heavy spring snowstorms, or the occasional fall snowstorm, leading to heavy branches falling on roofs and vehicles. In addition to the dangers of breaking limbs, the trees do not have a very favorable appearance, with an awkward branching pattern. One doesn’t need to search too long before you find many Siberian elm seedlings sprouting up in unwanted spots in the urban landscape. The sprouts show up in shrub beds where they are difficult to remove by hand and hard to spray with herbicides without damaging neighboring desired plant materials. Siberian elms are susceptible to damage from elm leaf beetles which leave the leaves looking skeletonized, but it doesn’t seem to kill the trees.  Notable horticulturalist Michael Dirr says the Siberian Elm is “one of, if not the, world’s worst trees…a poor ornamental that does not deserve to be planted anywhere”.

To be fair, I should mention that some people look favorably upon these four tree species, and say that in Colorado’s high desert climate (that is naturally and predominantly tree-less east of the Rocky Mountains), an invasive tree is better than no tree, especially in urban areas. I would beg to differ, noting that these trees are too difficult to control and remove, to the detriment of native flora and fauna. Please become aware of these invasive trees and be considerate about whether you want to allow these in your landscape.
