Background/Discussion Case No. P-17-05 On May 16, 2016, the City Council approved the preliminary plat of Miske Meadows. An update to the plat, which included 37 detached townhome units, was approved on January 17, 2017. The current preliminary plat request includes 251 buildable lots. The changes proposed with this update include reconfiguration of stormwater infrastructure between Johnson and Ivanhoe Streets to allow the addition of four additional lots. The changes also include a new stormwater basin, and relocation of the mid-block sidewalk connection between Johnson Street and Ivanhoe Drive. The applicant is also requesting approval of the Final Plat for Miske Meadows Third Addition. The plat will create 17 new buildable lots, two outlots, and an additional roadway connection between Ivanhoe th Street and 190 Lane NW. Site Plan In addition to allowing the addition of four buildable parcels, the changes to the stormwater plans reduce the lot depths for a number of lots. The typical lot depth for the impacted area has been reduced to 128 feet, but two parcels have a minimum depth of 120 feet. The standard lot depth for a typical single-family neighborhood is 130 feet. With the changes made after the first submittal staff is comfortable with the proposed lot depth reductions. The pedestrian connection between Johnson and Ivanhoe had aligned with Lincoln Street and the connection to Sunset Ridge. The proposal moves the pedestrian connection north, to a less than desirable location along the south side of wetland #2. The new location does not align with a sidewalk connection on either side, but due to changes in topography this may be the best alternative. To address concerns with the proposed sidewalk location staff recommends requiring pedestrian ramps on both sides of Johnson Street and Ivanhoe Drive, painted markings on the street to identify the crosswalk, and signage to inform motorists of the pedestrian crossing. Engineering and Utilities Mass grading for the site was completed last summer and installation of streets and utilities began this spring for Miske Meadows First and Second Additions. Staff’s initial concerns with the project were related to the design of the stormwater treatment infrastructure and the impacts to lot sizes and buildable areas. The current proposal meets all design standards. It should be noted the current stormwater design creates a situation where water will rise up and out of the catch basins in the back yards of some lots and lower as the pipes drain the water. This may be surprising to some residents, but the water will recede quickly. Due to the planned rise in water levels within these areas, staff recommends increasing the size of the easement along the rear property lines to mitigate the chance that structures could be temporarily inundated with water. Park Dedication No additional park land will be dedicated with this plat, but a cash dedication will be required with the filing of a final plat.
