Evermoor's Glendalough 5 10 Additions is a continuation of the Evermoor Glendalough neighborhood. The development consists of 188 single family residential units located on 97.45 acres located along the north side of Connemara Trail and west of Dodd Boulevard. The Evermoor of Glendalough 5 10 Additions are generally located in the eastern end of the Evermoor tract and these additions represent the last remaining areas in the Evermoor project. The 2009 Glendalough Addition and Glendalough 2n Addition is the next phase of the development to be completed, and is comprised of 23 single family residential units. This project has been designated as City Project No. 427. The proposed improvements include the construction of city streets that include concrete curb and gutter and 5 -foot concrete sidewalks. Utility improvements include the construction of storm sewer, as the majority of public utility improvements in the area to be platted were previously installed with the Evermoor's Glendalough 7 Addition, City Project 401, in 2006. 1. Streets City streets to be constructed as a part of 2009 Glendalough Glendalough 2n Additions include: Coachford Avenue Carlingford Court All proposed public streets are to be constructed to a width of 28 -feet with modified `S' (surmountable) concrete curb and gutter and with sidewalks along both sides. Coachford Avenue will be extended and a temporary cul de sac installed at its end. Future development will provide connections to 134 Street West and Carrach Avenue. Carlingford Court's construction with this project will provide a connection from Carlingford Lane to Dodd Boulevard at the development's east tract line. G: \ENGPROJ \427 \7 -21-09 CC AuthPln&Specdoc 2. Storm Sewer The majority of the lateral storm sewer system was installed with City Project 401 in 2006, as previously mentioned. Remaining storm sewer improvements proposed to be installed with this project include backyard catchbasins and limited lateral storm sewer and catchbasins within the future roadway. Storm catchbasins and manholes installed in 2006 with City Project 401 did include castings, and so only adjustments are necessary at this time with roadway construction. The site storm sewer system will be designed for a 10 -year rainfall event. Most of the stormwater runoff from the site will be directed to a large existing closed depression along the north side of the tract. This area has been designated as a regional stormwater management pond area in the Comprehensive Stormwater Management Plan. An existing storm lift station and force main system, again installed with City Project 401, will provide the controlled outlet for this area and will connect with an existing 18 -inch DIP force main stub constructed as part of the Connemara Trail storm sewer system. 3. Cost and Funding The total preliminary estimated project cost is $320,000, which includes a 20% contingency and 30% indirect costs. The funding for the lateral public improvements will be collected from the developer, US Homes Corporation (Lennar), and will fund 100% of project costs for streets and storm sewer. A cash deposit has been received from the developer to fund costs associated with preparation of plans and specifications for the project. 4. Schedule It is anticipated that the public improvements for 2009 Glendalough Glendalough 2 Additions, will be started late in the summer of 2009 and fully completed, including all restoration items except the bituminous wear course by the end of the 2009 construction season. The schedule for completion of the remaining Additions of Evermoor's Glendalough development will be determined by the developer, US Homes Corporation Lennar).
