The layout of lots and streets as shown on Exhibit 5, Illustrative Site Plan, is conceptual and shall remain slightly flexible in terms of layout, location and specific home orientation, so long as the development is in substantial conformance with approved subdivision for the Arboreta specific plan.
The overall community design concept for Arboreta is that of a gated, private, lifestyle that reflects the quiet residential nature of the surrounding community. Pedestrian linkages are provided to inter-connect all homesites with the passive park and neighborhood park. The focus of the site plan is an inward orientation, towards the central street scene and outward, with sensitivity to visual impacts to the surrounding perimeter streets.
A. 
Site Planning Measures. Specific site planning goals and techniques utilized in creation of the Illustrated Site Plan, Exhibit 5, include:
1. 
New adjacent single-family detached residences, which abut homes that front on Bennett shall all be single story, and shall incorporate increased rear year setbacks as established on the tentative tract map from the rear property line, including room additions, living space, decks and single story structures.
2. 
Passive open space adjacent to five single-family detached residences fronting on Bennett Avenue, as a rear yard buffer.
3. 
Varied massing of rear elevations of single-family detached and side elevations of townhome units facing Bennett Avenue and the MTA Railroad right-of-way.
4. 
Varied setbacks for single-family detached residences and town-home buildings facing Bennett Avenue and the MTA Railroad right-of-way.
5. 
Lowered pad elevations for single-family detached residences and townhome buildings, below street grade along Bennett Avenue, to minimize the visual impact of building masses.
6. 
Varied garage placement for single-family detached residences, setbacks and massing along the central community street scene.
7. 
Varied residential elevations along the central community street scene (single-family frontage and side elevations of townhomes.)
(Ord. 1835 § 2 Exh. A, 2006)
Arboreta is envisioned as a traditional neighborhood with two building types; single-family and attached. Neighborhood architecture includes eclectic Spanish, Craftsman, and Traditional styles, "classic" styles with appropriate massing. These styles include a blend of architectural elements compatible with existing architectural character in surrounding neighborhoods. Some single story elements have been maintained in the proposed single-family detached and attached home design, to blend and complement the range of styles.
A. 
Building Mass. Building massing is varied by style. The Traditional style includes a two-story mass, true to style, while Craftsman has more movement, wall breaks, and single story elements. The Spanish style includes more wall mass and introduces a deck in the front elevation in contrast.
B. 
Roof Forms and Window Treatment. Proposed roof forms and window treatments are simple and classic, true to style, and vary per style. The Craftsman style introduces more gable end roofs, with more movement. Chimney treatments vary per style. Window treatments will also vary per style. With Spanish, windows are recessed or stucco trimmed. Craftsman style windows include trim that allows for color blocking. The Traditional style shutters and trim coincide with the siding.
C. 
Additional Building Components.
1. 
Accessory structures such as mailbox structures are designed so that they are consistent with the architectural style of the adjacent primary structures and compatible with the residential character of the neighborhood.
2. 
Community walls will be of durable material (e.g., stone, masonry or stucco-covered block) and of a design and color consistent with the residential character. These walls will be a maximum of six feet in height and be generously landscaped to prevent them from becoming a dominant visual element of the streetscape.
3. 
Sound walls as required shall include decorative elements to blend with approved architecture and community walls.
(Ord. 1835 § 2 Exh. A, 2006)
A. 
Landscape Concept. The community landscape concept (see Exhibit 13, Conceptual Landscape Plan) is intended to create a distinctive, diverse environment that will lend identity and character to the specific plan area. Consistent treatment of all landscaped areas is critical to the creation of a high-quality outdoor environment. The proposed landscape features, including a neighborhood pool and tot lot, are designed to enhance the project's interface with the surrounding environment and the adjacent community. The landscape concept suggests methods of treatments that might be considered. Alternative landscape concepts and designs that accomplish the stated objectives and intentions are permitted.

Exhibit 13:CONCEPTUAL LANDSCAPE PLAN
Title 21--Image-370.tif
1. 
Landscape treatments should utilize and adapt to landscape elements from the urban patterns found in the traditional neighborhoods of Southern California, including regularly planted shade trees and clustered plant groupings.
2. 
Landscape treatments should incorporate colorful plant material and evergreen trees in areas where such accents are appropriate.
3. 
Landscape improvements should require minimal maintenance and irrigation. The use of native and/or drought-tolerant plant material should be emphasized to the extent possible.
4. 
All public areas and rights-of-way shall have automatic irrigation systems (commercial grade, where applicable). Low volume spray heads and drip irrigation systems should be used and be compatible with any reclaimed water systems utilized.
5. 
Landscape plans shall consider service lines, traffic safety sight line requirements, and structures on adjacent properties to avoid conflicts as the trees and shrubs mature. Street trees and trees planted in privately owned landscaped areas near public walkways or street curbs should be selected and installed to prevent unreasonable damage to sidewalks, curbs, gutters and other public improvements.
6. 
Tree species with invasive root systems shall be oriented away from water lines, sewer lines or public rights-of-way (see subsection D, Plant Palette).
7. 
Landscape maintenance practices for public areas shall be provided by the HOA at regular intervals sufficient to promote plant health and appearance. Maintenance may include discing, mowing, pruning, clearing of debris, weed removal, replacement of dead plant material, and repair and replacement of non-functioning irrigation equipment.
8. 
Street trees shall be located so as to not prevent effective solar access.
9. 
All landscaping shall be maintained to prevent interference with emergency vehicle access.
10. 
Fire protection measures within the Oak Tree Preservation Area (Passive Park) shall be consistent with applicable measures of the city of Glendora and Fire Marshal.
11. 
Maintenance of Hook Channel easement landscape shall be managed by HOA consistent with other public area standards.
Exhibits 13(A)—(C) provide illustrated cross sections of key edge conditions surrounding the specific plan area, and proposed landscape treatments to help insure project compatibility with surrounding the neighborhood.

B. 
Streetscapes. The streetscape within the Arboreta will receive a distinct landscape design. The goal is to establish the neighborhood character with a street tree palette appropriate for the scale and architecture. Courtyard planting shall generally consist of vertical screen elements and flowering accent trees.
Street trees shall be consistent with the approved street tree or master landscape and irrigation plan.
1. 
Landscape treatments should generally utilize formally planted street trees, unless otherwise specified.
2. 
Street tree planting may generally utilize one or two (at the most) primary species for each street, consistent with approved master landscape and irrigation plan with a limited number of additional species used as accent.
3. 
Landscape vines shall be planted along perimeter walls to provide a softened streetscape.
4. 
In order to conserve water, landscaping of the ground plane may emphasize the use of shrubs, native grasses and mulches as well as turf.
5. 
Landscaping in public areas shall minimize the use of groundcover. Turf will be specially designed into public, open space and entries.
6. 
Masses of shrubs shall be limited to a few, extensively used species for each street. Variations to the basic species should selectively be used for accent and contrast.
7. 
A landscaped parkway will be provided along the south edge property line, as indicated on the tentative map.
C. 
Project Entries. Inspired by the architecture of the Green Brothers, the newest neighborhood in Glendora will welcome visitors with a Craftsman style entry to the project, using specimen coast live oaks with masses of ornamental grasses to create a rural feeling at the project entry. Beyond the entry, this theme is reinforced with a street lined forest of London Plane trees reminiscent of neighborhoods of the past. Special design emphasis is given to the main entry into the specific plan. The primary project entry will be enhanced with clusters of vertical screening elements and flowering accent trees on either side. The treatment of the primary and secondary entries will reinforce the overall community character while distinguishing the Arboreta project as a unique place.
The primary community entry is located off of Grand Avenue and is the most prominent point of arrival to the project (refer to Exhibit 14, Primary Community Entry). The landscape treatment will include:
1. 
Monumentation;
2. 
Interesting accent shrubs and trees;
3. 
Accent paving in pedestrian or vehicular areas.
The secondary community entry is located off of Bennett Avenue. This entry will utilize similar landscape treatment elements such as pilasters, walls and themed plan materials and paving or other details established by the primary community entry.
