- Landscape & Site Design Standards
_____
A.
Intent. The intent of the landscape and site design standards is to:
1.
Improve the image of the City and build value with a well-designed public realm coordinating streetscapes, open spaces, and lot frontages.
2.
Strengthen the character and quality of development and emphasize distinct areas throughout the City with natural landscape materials.
3.
Preserve the value of properties as new investment occurs.
4.
Coordinate landscape and design amenities across multiple sites with special attention to the consistent relationship between open areas of lots and streetscapes.
5.
Encourage site design that allows spaces to serve multiple aesthetic, screening, environmental, recreational or social functions.
6.
Provide comfort, spatial definition and visual interest to active spaces including walkways, civic spaces, parks, trails or other similar outdoor gathering places.
7.
Enhance the environmental and ecological function of un-built portions of sites, and protect and integrate established natural amenities rather than plant or design new ones.
8.
Screen and mitigate the visual, noise or other impacts of high-intensity areas of sites and buildings, or where the scale and pattern of development changes.
9.
Conserve water and shift to water-conscious landscape design that is regionally appropriate and specific to the arid Front Range climate.
10.
Support the provisions of the City's water dedication policy and water management strategies.
B.
Applicability. The standards of this Section shall apply to all new development except:
1.
Improvements or repairs to detached houses and duplexes that are not subject to a Site Improvement / Residential Design Review as provided in Section 2.05, and which are not part of a larger residential neighborhood or subdivision plan; and
2.
Improvements or repairs to existing development that do not result in an increase in building footprint or impervious surfaces by more than 10% or changes in use that do not result in an increase in intensity.
In cases where improvements or repairs increase the building footprint or impervious surface by more than 10% or changes intensity of use, the intent is to bring the site into full compliance with these standards, except that the Director may prorate the requirements to the extent of new development on the site where full compliance is not possible or practical.
(Ord. No. 2438, § 13, 1-2-2024)
A.
Design Objectives. Landscape plans shall meet the following design objectives:
1.
Frame important streets and emphasize gateways with street trees, landscape massing and other vertical elements.
2.
Promote storm water management and prevent erosion through infiltration, storage or conveyances that utilize natural landscape elements and site features.
3.
Create focal points, gathering places and pathways that enhance the comfort, interest and movement of pedestrians.
4.
Improve resource and energy efficiency with landscape arrangements that consider wind blocks, heat gain, water usage, slope and drainage patterns, and other elements inherent to the site.
5.
Encourage the protection and preservation of healthy plants that can meet current and future needs of the site through development.
B.
Site Elements and Planting Requirements. The required landscape shall be based on different elements of the site according to Table 8-1, Plant Requirements.
Figure 8-1 Landscape Design
The landscape requirements are allocated to different portions, and emphasize how
different landscape standards and designs should be used to serve different functions
on the site, including relating buildings and sites to the streetscape, adding comfort
and interest to active spaces, and screening, buffering or mitigating impacts on adjacent
areas.
C.
Credits for Existing Vegetation. Preservation of existing landscape material that is healthy and of a desirable species may count towards these requirements provided measures are taken to ensure the survival of the vegetation through construction and all other location and design standards are met.
1.
Landscape plans shall provide an inventory of all existing trees or significant woody vegetation including size, health, species and any that are proposed to be removed.
2.
Existing landscape credits shall only count towards the portion of the site where it is located, according to the site elements in Table 8-1. For example, an existing tree may only count towards the required planting for parking lot perimeters if it remains in the parking perimeter in the final design.
3.
Credits shall be on a 1 for 1 basis provided existing trees shall be at least 3-inch caliper to count. Landscape material that is of exceptional quality due to size, maturity and health may be credited on a 2 for 1 basis.
4.

5.
Trees or other existing landscape that contributes to the standard shall be identified on a landscape plan and protected by a construction fence installed for the entirety of construction around the Tree Protection Zone (TPZ). The TPZ shall be based on ANSI A300 Standards and Best Practices but be at least 15 feet from the trunk of any tree and to the extent of the drip line in all cases. Tree wells or retaining walls may be necessary to protect existing plants.
D.
Design &Location. The landscape required by Table 8-1 shall be arranged and designed on a particular site in a way that best achieves the intent and design objectives of this Article, considering the specific context, street frontage, property adjacencies and other elements proposed on the site. Required plantings shall be planted in the following specific locations and open spaces on the lot.
1.
Streetscape & Frontage Trees. Streetscape and frontage trees shall be located in line with other trees along the block to create a rhythm along the streetscape and enclosure of the tree canopy. In the absence of a clearly established line along the block, trees may be planted in the following locations where applicable and in order of priority.

On center between the sidewalk and curb where at least 6 feet of landscape area exists;
b.
5 to 10 feet from the back of curb where no sidewalk exists or from the sidewalk where sidewalks are attached;
c.
Within the first 5 feet of the front lot line where any constraints on the lot or in the right-of-way would prevent other preferred locations;
2.
Foundation Trees & Shrubs. Foundation plantings shall be located in open spaces abutting the building or in planting beds associated with the design of any hardscape along the building frontage.
a.
Ornamental and evergreen trees shall be located within 20 feet from the building.
