A. General Standards A.1 Community Vision Carriage House at the Villages at Riverdale is a residential community designed with the modern, active family in mind. Whether it be a single professional, young family, empty nesters or retirees, the livable community caters to a contemporary, active lifestyle within the context and patterning of a traditional single family home development. Community and residential design features such as available solar panels, energy efficient construction, and smaller yards with water wise landscapes, shared motor courts, and durable, low maintenance materials, all allow home ownership to exist in balance with personal economy, environmental preference and active lifestyles. Clusters of homes are arranged around and have garage access off of shared, brick paved auto-courts which both reduces the visual and environmental impacts of the typical residential driveway and significantly improves the streetscape by orienting porches and architectural facades toward the tree lined public streets. The typical cluster includes four units with two on the street and two in the rear oriented on a 45 degree angle. The result is a pleasing pattern of homes accessed off of a pedestrian friendly streetscape with improved landscaping and ample parking for guests. Smaller, individual lots provide enough personal outdoor space for each family without the need for excessive maintenance demands on the homeowner. In exchange, the community shares preserved natural open space, and pocket park with a children s play area, picnic pavilion and multi-use turf field, all within easy reach of every home. Paved multi-use trail extensions connect the community to the existing public trail system and adjacent neighborhoods. Public open spaces and park amenities, all front yard landscaping and the motor courts (including snow removal) will be maintained by a Homeowner s Association, a feature that increases the value of the community and adds significantly to the low maintenance living. A.2 Project Overview The Carriage House at Villages at Riverdale is a 9.9 acre infill community of detached, single family homes at the corner of 128 th Avenue and Tamarac Street. The parcel is bounded on the north by the open space of the Horizon Tributary; the south by 128 th Avenue and undeveloped land; the east by existing gas and overhead powerline easements and low density single family homes, and the west by Tamarac Street and traditional neighborhood development.
