Mr. Scott Harlicker February 21, 2001 Page 2 • 2. PRELIMINARY PLAT • Currently, the only access points for this plat are Waco Street in the southeast corner and 183rd Avenue in Big Lake Township in the southwest corner. • There could be access in the northeast corner of the plat which leads out to the realigned Waco Street. It is unclear whether it is reasonable for this plat to connect to that point. There are wetlands lying between the access point to Waco Street and the last street within the plat. • The street that extends to the northerly plat line along Buildings 1 and 2, Block 9, needs to be to City standards. This will be the route that will provide one access point to the 10 acres to the north. 3. GRADING, DRAINAGE, AND WETLAND MITIGATION • There are two points on Waco Circle where wetlands will be impacted by constructing the road. There is also a portion in the northern part of the plat where street construction will impact wetlands. There is wetland mitigation shown on the plan; however, no Technical Evaluation Panel has been held at this point to review the wetland issues. The plat will have to go through a TEP review and meet all the conditions set forth. • All of the wetland areas, wetland mitigation areas, and ponding areas will need to be within drainage and utility easements. It is unclear whether all of the common space in this development will be designated as drainage and • utility easement. If not, specific easements will need to be provided around the wetland and ponding areas. • If another City street were extended to the property to the north from the northwest portion of the plat, the property to the north could potentially develop without filling wetlands for road purposes. • Not enough detail is shown at the southerly, westerly, and northerly boundaries to determine whether the grading matches adjacent properties. • There are several locations in the development where drainage crosses lot lines, emergency overflow elevations are missing, and other specific drainage issues need to be detailed. We believe all of these can be reasonably accomplished. We will be meeting with the Developer's engineer to go through these issues in detail prior to the submittal of the final grading plan. • There is an approximately 5-acre piece with a single-family homestead on it in the northeast corner. We question whether public street access should be provided to the property line of this parcel, should it be subdivided in the future. • There is no park area shown on the plat. Given the 178 units proposed, it would seem reasonable that some small park area for playground equipment be provided. 4. UTILITY PLAN • Sanitary sewer will be provided from a stub in the southeast corner of the plat. All of the sanitary sewer extended through the development will be considered public utilities and will need to fall within public rights-of-way or easements. Sanitary sewer needs to be extended to the north limits of the 0:\PROJ\812970J\0240\Ltr 02-19-01 McPherson.rev.doc Howarc R. Green CoTcany CONSULTING ENGINEERS
