landscape. Drought tolerant trees will be placed in strategic locations to help create a diverse habitat. The Mason
Road streetscape is designed to enjoy the conditions of the restored prairie by meandering the, sidewalk through this
environment. On the north side of the prairie, native evergreens are anticipated to help buffer the development from
the adjacent property. The plan anticipates using bubbler irrigation heads at the trees and spray heads for the prairie.
However, it is anticipated that once the prairie is 90% established, the irrigation will only be used during extreme
conditions.

Exhibit `A'
Union Place - Landscaae Plan — Alternative Comuliance
The proposed landscape plan for. Union Place is grounded in an environmental sustainable approach. This is
achieved by grading the property using micro -detentions and bio swales to help as a best -management practice for
storm water. In addition, all plant material has been chosen using drought -tolerant and micro -climate selection
process. This ensures that species are to be used that minimize the need for water consumption, while providing the
best landscape for human comfort. This is especially true for the street tree environment. All plant material will
meet the American Association of Nurserymen standards and soil specifications will ensure high quality growing
conditions:
The landscape plan is broken down in to four significant categories, all which are linked together through a common
landscape dialogue. All four categories are designed to complement one another, ensuring a seamless transition of
environmental significance. The categories include:
Willox Retail Frontage
Residential Streets and Parks
Parking Lots
Urban Prairie
The Willox Retail Frontage has been designed to create a streetscape environment that if focused on shade and
human comfort, reduction of heat island 'effect, creation of an inviting `welcome mat' to the development and
seasonal color, while providing an.inviting and vibrant retail atmosphere. The use of drought tolerant street trees, to
be planted every 30 feet on center, drought tolerant grasses and impervious pavers will assist in providing the
environment listed above. To reduce irrigation demand, the plan anticipates using bubbler irrigation heads at the
street trees, drip irrigation for all planting beds and small spray heads to cover any turf areas. This will force the
water to be placed directly on the plant material needing it compared to over -spraying or evaporation.
The Residential Streets and Parks systems are designed to create environments that provide comfort and safe
accessibility. All Residential Streets are to be lined with drought -tolerant street trees, planted every 30 feet on
center, with a variety of tree species allowing for variety in seasonal color and interest. This will also contribute to
the diversity of the urban forest. The under story will be drought tolerant, Enviro-Turf. All of the neighborhood
parks will be designed as depressed micro -detentions, which will assist in the green -infrastructure proposed for the
development. The depressed areas will be appropriately drained and will be designed as green space for to be
utilized for recreational activities. All of the parks will be lined with drought tolerant trees, seating and pedestrian
level lighting. It is the intent that the streetscape system .will be the green conduit that connects one park to the next.

This will force the water to be placed directly on the plant material needing it compared to over -spraying or
evaporation.
The Parking Lots have an environment similar to the residential streets by providing safe accessibility between the
parking lots and the buildings. These sidewalks will be lined with ornamental & shade trees and pedestrian level
lighting to define a separation from the parking. The shade trees will be in landscape islands that will vary in size
and placement. To further soften the space between the parking lots and building, recessed areas along the building
facade will have foundation plantings and seating. Irrigation will be similar to those already described.
The Urban Prairie system returns the native landscape of the Front Range to Union Place. The area around the
detention ponds and along the northern boundary is designed to incorporate a drought tolerant prairie mix of 70%
native grasses and 30% native wildflowers. In addition, a crushed gravel pathway is anticipated to run through the
