Preliminary Plat and Site Plan Reivew Rivenwick 4th March 5, 2004, revised April 9, 2004 Page 4 of 8 7. Structure Height. Information will need to be provided regarding the height of the structures. The structures will not exceed 35 feet in height as measured from the mean ground level to the mean ground gable. o Off-Street Parking Requirements: The proposed development is required to provide a minimum of 390 off-street parking stalls (2 parking stalls per unit). The proposed townhouse units will all .have a two stall garage and many units are providing for a 25 foot driveway. The proposed garage and driveway pad will provide enough area for 2 off-street parking stalls in most cases. In cases where a unit's garage gains access from a 24 foot wide street and the driveway is less than 25 feet, a secondary street that allows for parking is located adjacent to the unit. The plan is also providing for 6 additional parking stalls located within a parking node. Urban Townhome units 61-68 and 52-60 have 23 foot driveway's and have limited access to a public street. It is staff's opinion that additional parking spaces need to be provided for these units. This can be accomplished several different ways: extend the driveways to 25 feet, provide additional parking spaces in close proximity to the units, or widen the private street to a 28 feet. Maximum Driveway Width at Street Frontage: City Code stipulates that a driveway must be a maximum of 20 feet where it abuts the street. It appears that the development complies with this requirement, however the plan should be revised to include this information in order for staff to verify compliance. 10. Open Space: The R-3 District requires a development to provide at least 40 % open space area for future resident enjoyment. Qualifying areas include grassed lawns, landscape areas, gardens, natural areas, landscape rock, mulch, wetlands, and ponding areas. City Code also states that of the 40% open space area 10% must be dedicated as an identifiable common area. The development is providing 42% (332,148 square feet) green space area. The preliminary plat is showing one common open space area that is 1 acre (43,560 square feet) in size; this exceeds the 10% open space area requirement. The common open space area will be completed with a pergola, park benches and tables. This common area does not need to include a tot lot as there is a nice active park located immediately adjacent to the subject project. 11. Access and Streets. The submitted plan shows that most units will front onto private streets. The Home Owners Association Covenants must plainly point out that private streets are not eligible for conversion to public streets at a future date. The proposed plat will accommodate 195 units, which will be serviced by Riverdale Drive. Riverdale Drive is an MSA road and will connect to 138th Avenue and also Garnet Street near the east end of the plat and Highway # 10 west of the subdivision. 12. Grading and Drainage: A grading plan has been submitted and the following items still need to be added to the grading and drainage plans. · Submit soil boring locations with a report outlining soil types and depth to groundwater Submit storm water calculations that clearly demonstrate the impact this site will have on the regional storm water system. The applicant is proposing to fill half of the existing pond, vacate the existing storm water pond easements and create new easements over the smaller pond. The applicant has
