3. Design Principles.

a. Landscape plans shall use the following design principles to promote the desired character of the community, connectivity, and enhance the aesthetic while maximizing reductions in energy and resource consumption and minimizing maintenance requirements:

(1) Well-planned site design using appropriate building orientation, building materials, thematic design, and planting schemes that incorporate climatic and micro-climatic conditions to promote the wise use of water and energy resources;

(2) Appropriate site and building materials, plant, and turf selection and placement to minimize energy, resource consumption, and maintenance requirements;

(3) Maintain soil moisture and reduce evaporation through the maximum use of layered landscaping such as organic mulch, ground cover, shrubs, forbes, and over-story landscaping;

(4) Zoning of plant materials according to microclimatic needs and water requirements;

(5) Improvement of the soil as needed to promote plant health and longevity;

(6) Efficient irrigation systems with weather and rain gauges to minimize resource consumption, waste, and maximize efficient water use;

(7) Proper plant maintenance, care, and irrigation schedules;

(8) Safe and healthy landscapes that provide for alternative modes of transportation. Landscapes shall provide access to all ages and abilities and reduce opportunities for illicit activity or behavior. Landscaping at pedestrian and vehicle intersections shall meet view triangle requirements as noted in the approved version of the Town of Frederick Design Standards and Construction Specifications, as they may be amended from time to time;

(9) Encourage the use of permeable construction materials and systems that minimize storm water runoff and maximize infiltration while reducing the potential for non-point source groundwater pollution, including incorporating storm water detention into the landscape design;

(10) Seasonal variation in interest, as well as framing and buffering of views, and the careful placement of over story and under story materials to block winter winds and summer sun.

(a) All landscape shall strive to maximize use of native species. Where native plant material is not appropriate for the intended use, plant species that are regionally adapted and noninvasive may be used.

(b) Landscapes shall consist of a variety of plant species to enhance biodiversity. No one plant species may make up more than twenty-five percent (25%) of the non-grass plant materials on site.

(c) Buildings and parking areas shall be located to preserve and promote the health of existing vegetation, environmental resources, and natural drainage ways. No healthy tree or shrub shall be removed without good cause. This requirement is not intended to prevent removal of unhealthy plants in conjunction with development.

(d) Landscaping shall be placed to provide summer shade and limit winter shade and wind on walks and streets.

(e) A combination of plantings, berms, walls, and fences shall be used as appropriate to buffer adjacent uses, sensitive habitat, and transition between elevation changes (see Figures 2.7 (a) and (b)).

(f) All areas disturbed by construction shall be reseeded to prevent erosion. Native, non-invasive grasses shall be used for re-vegetation where practical. Weed control is the responsibility of the landowner or approved designee.

(g) All parks and open space shall be developed, landscaped, and maintained as noted in Section 2.11 of this code.
