The development is located at 798 North 500th Avenue, immediately north of the existing Sunset Ridge Subdivision; and, WHEREAS,the property was annexed in February 2022. The initial Rezoning with Master Plan was initially approved on September 13, 2022,which rezoned the property from Agricultural (A) to Floating Suburban — Residential Low Density (FS-RL). Amendments were approved on February 28, 2023, and May 23, 2023, to allow for attached single family and detached single family housing; and, WHEREAS, the estimated density calculation is 5.05 units/acre, for the developable area, which meets the minimum 3.75 units/acre required by the FS-RL zoning and amended Master Plan. As indicated on the amended Master Plan, Wilder Avenue and Ellston Avenue will be extended northward into the development and will provide access from the development south to Lincoln Way. Wilder Avenue is designated as a residential collector street. It will also extend through the development to the north property line for future development and connection to the future City park; and, WHEREAS,the proposed Greene Street will bisect the development and provide east-west access. Greene Street ends in a cul-de-sac on the east. The length of the cul-de-sac exceeds the length generally allowed of 600 feet,but given the constraints of the site, staff has determined that it is not feasible for other connections to the east, south, or north. Although this condition is typically avoided, the designated length of the cul-de-sac street is within the approvable limits of the Subdivision Code of 1,320 feet. If the City was not planning to develop a park to the north, a connection to the north in addition to Wilder Avenue would be required. Greene Street is stubbed on the west end at Outlot XX. It is anticipated that future development to the north will connect into Greene Street and extend to North 500th Avenue; and, WHEREAS, accommodation and coordination of street trees with final improvement plans related to streetlights, fire hydrants, and single-family attached unit driveways will be a condition of final plat approval. Installation of sidewalks is required with all residential subdivisions per Section 23.403.A 5-foot sidewalk will be constructed along both sides of all internal streets,except on the west side of Wilder Avenue, which will include an 8-foot shared use path; and, WHEREAS, the general pattern of open space and stormwater detention proposed within the development reflects the layout included on the Amended Master Plan and includes approximately nine acres. Outlot C(3.64 acres or 13%)has been identified as"usable"or common open space. The FS-RL zoning district requires at least 10% of the acreage to be common open space for passive or active recreation. Outlot C will include a sidewalk connection from Greene Street extending through the parcel to address the FS zoning requirement related to open space. The exact location of the sidewalk is still to be determined as the elements of the future park to the north are unknown at this time. If the sidewalk is not able to connect into the proposed future city park, it will need to extend through the parcel to Wilder Street; and, WHEREAS, on the far eastern side of the property, there is an area of floodplain located within Outlot D. All of Outlot D is identified as open space as indicated on the Amended Master Plan including this floodplain area. It is intended that this area will remain vegetated in native tree cover. All residential lots are located outside of flood prone areas; and, WHEREAS, all four of the outlots (Outlot A, B, C, & D) will include storm sewer and surface water flowage easements over the entire lot. Stormwater will be conveyed through outlots to a stormwater detention basin located on the north side of Greene Street, across from lots 33, 34, and 35. The overflow for the basin will convey water offsite to an existing channel and pipe which conveys the water to Clear Creek. A permanent sanitary sewer and stormwater flowage easement also exists over Parcel P, off-site but adjacent to the development on the north. Public Works finds the proposed storm water management plan design conforms to the City standards of Chapter 5b and has received a signed and sealed copy as required; and, WHEREAS, sanitary sewer will serve the site with the extension of a 12-inch trunk line into the development from the northeast. It will continue down Greene Street as a 12-inch trunk line to the west, concluding at a manhole in the right-of-way at North 500th Avenue. It has been upsized from the standard 8-inch line, for the purpose of serving westward expansion of the City. The trunk line extensions were part of the Amended Contract Rezoning Agreement. An 8-inch sewer line will extend from Greene Street at Wilder Avenue and will stub at the north property line; and, WHEREAS, notice was mailed to property owners within 200 feet of the subject site and a sign was posted at 798 North 500th Avenue and the north end of Wilder Avenue. As of this writing, no comments have been received. NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Ames, Iowa, that Preliminary Plat for North Sunset Ridge (798 N 500th Avenue) is hereby approved with conditions as follows: A. The exact location of the sidewalk connection north to the future park is still to be determined. If the sidewalk is not able to connect to the park, then it will need to extend through Outlot C to the west and connect with the Wilder Avenue sidewalk/trail.This determination will occur by the City Council at the time of Final Plat approval. B. Accommodation and coordination of street trees with final improvement plans related to streetlights, fire hydrants, and single-family attached unit driveways will require submittal of a plan to be reviewed and approved by the Planning Division prior to Final Plat approval.
