Guide Plan Designation: LDR—Low Density Residential Current Zoning: R-1,Low Density Residential with the Prestwick Place Planned Unit Development (R-1: PUD) The applicant,Lennar Corporation (Lennar),requests approval of a Final Plat for Prestwick Place 9th Addition to allow development of eight (8) single family lots. The final plat is necessary to facilitate subdivision of the subject property into individual residential lots. The public streets and associated infrastructure to serve the six lots were constructed in 2013 with the Prestwick Place 7th Addition development and therefore there are no new public improvements needed for this plat. Staff finds the application consistent with the Prestwick Place 9th Addition Preliminary Plat that was approved by the City Council on July 16,2013 and recommends approval of this application subject to the conditions detailed in the attached resolutions. ISSUE ANALYSIS Legal Authority. This application is a Quasi Judicial action. The final plat application is Quasi-Judicial because the City has a set of standards and requirements for reviewing this type of application that is described in detail below. Generally,if the final plat meets the ordinance requirements it must be approved. Streets&Access. On April 16, 2013, the City Council approved the Prestwick Place 7th Addition that approved the 37 lots south of Albany Avenue and east of Aldborough Avenue. In the fall of 2013, the City complete the construction of Albany and Aldborough Avenues and the associated infrastructure for Prestwick Place 7th,which included individual sewer and water services to the north of Albany Avenue and west of Aldborough Avenue. The eight (8) lots requested will use these streets and infrastructure. No new streets or infrastructure is requested or required in the Prestwick Place 9th Final Plat. Final Plat. On July 16, 2013, the City Council approved the Prestwick Place 9th Addition Preliminary Plat that included the 68 lots located north of Albany Avenue,west of Aldborough Avenue and south of Connemara Trail. Tonight,Lennar is requesting approval of the eight (8) lots that can be developed using existing streets and infrastructure. The request is for two lots west of Aldborough Avenue (Lots 1 and 2, Block 1) and six (6) lots north of Albany Avenue (Lots 1 through 6, Block 2). The plat includes three outlots (Outlot A,B and C). Outlot A is the area over the trunk stormwater line that is the overflow for the stormwater pond located southwest of the plat. Outlot B is for the north half of Prestwick Park and a stormwater pond. Outlot C will be retained by Lennar for the future development. Grading. The grading plan depicts the entire 68 lots of the Prestwick Place 9th Preliminary Plat,Prestwick Park and neighboring stormwater pond. Grading permits can be issued after preliminary plat approval, so the City Engineer is expecting to issue the administrative grading permit for the entire 68 lot area even though the Final Plat will only allow homes to be constructed on the eight (8) lots. No additional streets will be constructed with the grading, but the stormwater infrastructure directly associated with the stormwater pond will be installed by the developer when grading of the pond. Parks and Open Space. The Parks and Recreation Department conducted a park dedication analysis during the overall Prestwick Place Preliminary Plat review. The park dedication of Prestwick Park has been created to Lennar. The credit remaining after Prestwick Place 7th was 0.40 acres. The City Code requires park dedication of 1 acre of parkland per 25 homes, or an equivalent of 0.04 acres per lot. The eight (8) lots requested will use 0.32 acres of the credit,leaving 0.08 acres of credit (two homes worth) for the next Lennar final plat. Lanner will grade and deed Oudot B to the City as a part of the Prestwick Place 9th Final Plat. Comments regarding this application are detailed in the attached memo dated March 20, 2014. 2 Engineering Comments. The Assistant City Engineer has reviewed the proposed Prestwick Place 9th Addition Final Plat and the grading plan for the entire Prestwick Place 9th Addition Preliminary Plat and has a few minor concerns. Comments regarding this application are detailed in the attached memo dated March 19, 2014 and are labeled specifically for either the final plat or the grading plan. CONCLUSION & RECOMMENDATION Staff recommends approval of the Final Plat for Prestwick Place 9th Addition creating eight (8) single family lots. This recommendation is based on the information submitted by the applicant, findings made in this report and the conditions detailed in the attached memorandums. 3 1 Pia, 1 i_ r 13----1 _..rte .

Storm sewer is proposed along the side and back lot lines of certain properties to convey rear yard drainage. Drainage and utility easements along these lines shall prohibit the installation of sheds to ensure that access can be provided for storm sewer maintenance. Fences are allowed but shall not restrict drainage and are required to include gates for truck access over the drainage and utility easement. Also,landscaping that will block access should be prohibited. These restrictions should be added as a restriction on the property deed. This will impact the following properties: • Block 1A: Lot 1 through Lot 5 • Block 2A: Lot 4 and Lot 5 • Block 3A: Lot 1 through Lot 6 • Block 4: Lot 1 through Lot 4,Lot 9,Lot 10,Lot 13 through Lot 18,Lot 23 through Lot 35 9. Trees should not be located over storm sewer pipes or within emergency overflow routes or overland flow routes. Additionally, trees located on individual properties should not be planted near the sanitary sewer and water service lines. These trees should be positioned a minimum of 15 feet from the service lines. 10. The width of drainage and utility easements over all public utilities shall be verified during final design. 11. Drainage and utility easements in the rear yards of many lots are required to be extended based on the proposed emergency overflow elevation. Below is a listing of lots where the drainage and utility easements require revisions. • Block 1A: Lot 1 and Lot 2 should be increased to encompass the drainage to 938.8 (E.O.F. - 938.3). • Block 1A: Lot 3 through Lot 6 should be increased to encompass the drainage to 938.0 (E.O.F. - 937.5). • Block 3A:Lot 4 through Lot 6 should be increased to encompass the drainage to 937.4 (E.O.F. - 936.9). • Block 4A: Lot 1 through Lot 4,Lot 5,Lot 6,Lot 14,Lot 15,Lot 26 through Lot 28,Lot 31 through Lot 35 should be increased to encompass the drainage to 931.5 (E.O.F. - 931.0). • Block 4A: Lot 2 and Lot 25 should be increased to encompass the drainage to 931.8 (E.O.F. - 931.3). • Block 4A: Lot 5,Lot 6, and Lot 23 should be increased to encompass the drainage to 932.5 (E.O.F. - 932.0). 12. Drainage and utility easements in the front yards of lots in Alma Circle (Lot 25 through Lot 30,Block 4) are required to be increased to encompass the drainage to 934.7 (E.O.F. - 934.2). STORMWATER MANAGEMENT: 13. The storm sewer drainage area map and storm sewer design calculations should be provided. The preliminary design is used to verify the adequacy of the easements being provided over rear yard storm sewer. 14. Additional infiltration testing data is required to verify that the rate control design is in conformance with City requirements. The infiltration testing should be completed during site grading and at the proposed grading plan elevations. 15. The pipe invert elevations, outlet control elevations,and pipe sizes for Pond P5 and the infiltration basin should be shown on the plan. 16. An emergency overflow route is required east of Block 2A,Lot 11 to convey street drainage. 17. The proposed storm sewer line appears to conflict with an existing sanitary manhole northwest of 142nd Street and Aldborough Avenue.The storm sewer should be relocated to the South side of 142nd Street. 18. The low building opening of Lot 6,Block 3 is required to be raised to provide 1.5 feet of freeboard from the rear yard drainage EOF. The proposed elevation provides 1.2 feet of freeboard.
