EXECUTIVE SUMMARY The Greystone 1 S ` Addition Project, City Project No. 439, was initiated by Ryland Homes with a proposal to develop a 23 unit sinble family housing development. A second phase consisting of 31 single family homes is included on the preliminary plat. The site is located approximately 2700 feet north of 145`" Street W(County Road 42) and east of and adjacent to Akron Avenue (County Road 73) (Refer to Appendix A for a Project Location Map). As part of the improvements associated with the first phase, a minor collector roadway is proposed to extend east from Akron Avenue. This roadway is planned to be constructed to a 48- foot width which will allow adequate room for turn lanes. Trunk sanitary sewer is proposed to serve development to the north, south, and east of Greystone l Addition. An existing storm water pond will be relocated to the southeast corner of the property. It is estimated that the total costs associated with the construction of the first phase is $1,129,200. A detailed cost estimate for the project can be found in Appendix B of this report. It is proposed that the construction of Greystone 1 s` Addition be completed as outlined in this feasibility report. This project is feasible, necessary, and cost-effective from an engineering standpoint, and should be constructed as proposed herein.

STREET IMPROVEMENT PROJECT 2.1 Introduction 2.1.1 Authorization On April 3, 2012, the Rosemount City Council authorized the preparation of an Engineering Feasibility Report for the Greystone l Addition Improvements. This project has been designated as City Project No. 439. 21.2 Scope This report addresses the construction of street and utility improvements necessary for the Greystone ls` Addition residential development. The proposed improvements include the construction of public streets with concrete curb and gutter, an 8-foot bituminous trail, and 5-foot concrete sidewalks. Utility improvements include the construction of trunk and lateral sanitary sewer, water main, and trunk and lateral storm sewer. 2.1.3 Data Availahle Information and materials used in the preparation of this report include the fo(lowing: ■ City of Rosemount Utility Plans ■ City of Rosemount Record Plans ■ City of Rosemount Topography� Maps ■ Proposed Utility and Grading Plans prepared by Pioneer Engineering, dated February 13, 2012. ■ Preliminary Plat ■ Proposed Final Plat 2.2 General Background 2.2.1 Project Location The project area is located east of Akron Avenue and north of CSAH 42. This area is currently zoned MDR (Medium Density Residential) and is located within the Metropolitan Urban Service Area (MUSA). 2.3 Existing Conditions 2.3.1 Surfuce The area consists of agricultural land with existing road access from Akron Avenue. A map showing the project area can be found in Appendix A. Fensibiliry Report Gre}�stone /" Addition Cit�� of Rosemount Project No. 439 WSB Projecl No. l916-66 Page 2 2.3.2 Sanitary Sewer Trunk sanitary sewer is located along Akron Avenue. An existing 8-inch sanitary sewer stub is available to serve the Greystone l Addition. 2.3.3 Water Main The existing trunk water main is located along Akron Avenue. An existing 8-inch ductile iron pipe water main is stub is available to serve the Greystone ] Addition. 2.3.4 Storm Sewer The existing trunk storm sewer from Akron Avenue discharges at the northwest corner of the first phase of Greystone 1 St Addition. A stormwater pond is currently at this location. 2.4 Proposed Improvements 2.4.1 Surfuce A 48-foot-wide minor collector roadway connection to Akron Avenue is proposed as part of the Greystone 1 St Addition improvements. 32-foot-wide local streets will comprise the remaining roadways within Greystone 1 St Addition. A map showing the proposed roadways can be found in Appendix A. As part of the future roadway network east of Akron Avenue, the alignments and traffic volumes of the major and minor collector roadways were analyzed. This analysis can be found in the Collector Roudwuy Analysis memo attached in Appendix C. Intersection configurations at Akron Avenue and the intersection east of Akron Avenue will be as follows: Intersection at Akron Avenue � Westbound o Right-thru lane ■ 13 feet wide o Left turn lane ■ 13 feet wide ■ 220 feet turn lane length • Eastbound 0 14 feet wide Feasibilit}� Report Gre}�stone 1"Addition Cin� of Rosemount Projee� No. 439 N'SB Projecl No. !9/6-66 Pa�e 3 Intersection east of Akron Avenue • West leg o Eastbound ■ 13 foot wide left turn lane ■ 13 foot wide right turn lane o Westbound thru lane ■ 14 feet wide � South leg o Northbound ■ 12 feet wide left turn lane ■ 12 feet wide thru lane o Southbound ■ 12 feet wide thru lane • North leg o Northbound ■ 12 feet wide thru lane o Southbound ■ 12 feet wide right-thru lane The north leg of the intersection east of Akron Avenue is proposed to taper from a 36-foot-wide roadway to a 32-foot-wide roadway. A striped median on the north leg of the intersection is required to align the intersection north and south of the minor collector. 2.4.2 Sanitary Sewer A 10-inch sanitary sewer line will be connected to an existing 8-inch sanitary sewer stub from Akron Avenue. A memo outlining the sanitary sewer connection at Akron Avenue has been attached in Appendix D. This line will be extended north through the first phase of Greystone to provide capacity for future developments north and east of Greystone 1 St Addition. The capacity of the mainline sanitary sewer is designed to handle approximately 26 acres of inedium density residential development north of Greystone as guided with the City's 2030 Comprehensive Plan. In addition, the sanitary sewer has the capacity to serve the equivalent of approximately 1 10 additional single family homes east of the medium density residential land. A determination of the exact sewershed limits will need to be analyzed and approved with individual grading plans. 2.4.3 Wuter Main An 8-inch ductile iron pipe water main will be connected to the existing ductile iron stub from Akron Avenue. The water main will be routed along all streets throughout Greystone l Addition. Regiona(ly, a future 12-inch trunk water main is required to be installed south of the railroad tracks to loop the existing trunk water main. This connection will be required with the development of the property east of Akron Avenue and north of Greystone. Fensibiliry Report Grepslone 1"Addition Ciry ofRosemounl Project No. 439 k S8 Project No. 1916-66 Page � 2.4.4 Storm Sewer The existing stocmwater pond in the nortllwest corner of Greystone I S ` Addition is proposed to be relocated to the southeast corner of the development. The new stormwater pond at this location will handle the existing flow from Akron Avenue as well as runoff from the Greystone Additions. Trunk storm sewer will convey the 100-year runoff from Akron Avenue and will allow for a future connection to the City's trunk outlet. Easement for the existing stormwater pond was purchased from the property owner for the construction of Akron Avenue. The developer is responsible for the costs associated with the pond relocation. The City will be responsible for the equivalent cost of a trunk storm sewer system extended straight east. The developer will be responsible for the additional cost to extend the pipe to the southeast corner of the property and increased pipe size due to runoff from the development. 2.4.5 Permits/f1 pprovals The anticipated permits and approvais that will be required for this project and the respective agencies are listed below: • Minnesota Department of Health ...................................................

Director of Public Works/ City Engineer City of Rosemount From: Charles Rickart, PE, PTOE Transportation Engineer Date: March 28, 2012 Re: Collector Road Analysis Akron Avenue to Blaine Avenue B��CI�GROUND In 2007 the Ciry of Rosemount completed an �1lternative L�rban rlrea�vide Re��ie�v (r1L' �R) that analyzed the de�-elopment of land in Rosemount east of do�vnto�vn. The land reaie�ved extends from approximatel� 2600 feet �vest of �kron �1�-enue to approximately 5200 feet east of r�kron Avenue. This land is bounded on the north by I�onaire Path and on the south by 145`� Street. The AUAR details the location of future minor and major collector road�vays throughout this corridor. The projected traffic volumes of the major collector road�va�-s �vere also determined �vith the �U�R. Traffic volumes for the minor collector road�va��s �vere not determined. AI�RON 1-�VENLTE CORRIDOR In the last fe�v 5�ears, development along the I�kron ��venue corridor has started taking place. Development west of Akron Avenue began in 2011. I Iousing demand is no�v proposed east of Akron Avcnue. r� �vell planned net�vork requires determining the traffic � olumes of the minor collector road�va}�s. This information along with a closer re�-ie�v of the land use helps de�relop a comprehensi�-e road�va�� plan �vith intersection needs plan to assist �vith right-of-�va�• dedication. The attached map shows the recommended road�vay alignments foY the majoY and minor collector road�vays bounded by the Akron Avenue, Blaine l�venue, Bonaire Path, and CS �H 42. The road�va�- alignments are similar to the proposed alignments in the 2030 Comprehensi�-e Plan �vith the follo�ving eYCeptions: Minneapolis ■ St. Cloud Equal Opportunity Employer � 1�linor collector road�va�� eYtending north from l�udrey l�venue has gradual cun�e that shifts the Yoad�vay alignment appYOximately 700 feet west of rludrey rlvenue a b�� the rime the road reaches Bonaire Path. • Alinor east-�vest collector approtimatel}� ?600 feet north of 1��`� Street is planned for construction �vith a tee intersecuon east oElll;ron ��-enue. The tee intersection �vould be located approximately 500 feet east of r�kron rl�renue. The alignment changes of the minor collector road�va��s �vere made for the follo�ving reasons: • Better align �vith anticipated land use of the current propern- o�vners along this corridor. Due to Flint Hills pro�imit�� to the area and their current land o�vnership it is likel�- that the minor collector road�va`- eYtending north from �udrey rlvenue �vill be constructed closer to the alignment shown on the attached map. • East-west collector 2600 feet north of 145`" Street was modified to a tee intersection due to physical constraints. There is an existing transmission line running east-�vest just south of the collector road�vay. The spacing of the transmission poles �vill not allo�v for the collector roadway alignment to cur�re bet�veen them �vhile allo�ving an access road to the north and adequate turn lane lengths at r�kron r�venue. The anticipated traffic ��olumes of the minor collector, major collector, and arterial roadwa�-s ha�-e also been pro�-ided on the attached map. These traffic �-olumes represent full de�-elopment of land in the area �vith consideration to the land use of the land o�vned by Flint Hills. A minimum right-of-�va�� of �vidth of 80 feet is recommended for all minor collector road�va��s and 100 feet for all major collector road�va}�s. �dditional right-of-�va�- �vidth ma�� be needed at intersections to allo�v for turn lane construction. �-�ll intersecuons �vill require a minimum of t�vo lanes of approach and one lane of departure for traffic. The intersection of Connemara Trail and Akron rlvenue and the intersection of Connemara Trail and Blaine r�venue will require three lanes of approach and one lane of departure. The right-of-�va�- �vidth needed at these locations �vill likely be 120 feet. r1s land de�-elops around future intersections, analysis �vill need to be completed to define turn lane lengths and �vidths along �vith subsequent right-of-�va�� �vidths needed at these locations. cc: Phil Olson, Assistant City Fngineer Collector Roadway Analysis Page 2 Akron Avenue to Blaine Avenue March 28, 2012 APPENDIX D Akron Avenue Trunk Sanitary Sewer Memo .

Date: Februnr�� 22, 2012 Re: Akron Avenue Trunk Sewer — 8" Lateral Sewers City of Rosemount, MN WSB Project No. 1005-00 BACKGROUND The City's Comprehensive Sanitary Sewer System Plan (CSSSP) indicates wastewater in the North Central Sewer District and west of Akron is designed to flow to the 24-inch Akron Avenue trunk sewer through 8-inch and 10-inch sewer laterals constructed at minimum grade (0.4% and 0.28%) in accordance with 10-State Standards. The attached Figure 6-2 from the CSSSP shows the later tr�ink sewers planned. As part of the Akron Avenue trunk sewer installation project, an 8-inch lateral sewer was extended 114 feet east from the future intersection of Akron Avenue and Connemara Trail at a slope of 0.35%. EVALUATION Although the 8-inch sewer lateral was not constructed in accordance with the CSSSP, an 8-inch sewer can provide the same capacity as a 10-inch sanitary sewer when the invert is surcharged, causing the sewer to flow under pressure. Based on our calculations, a surcharge of 0.5 feet above the top of the 8-inch sewer would result in capacity equivalent to a 10-inch sewer constructed at 0.28% which is the minimum grade of installation in accordance with 10-State Standards. The surcharge required above the top of the 8-inch sewer to provide equivalent flow of a 10-inch sewer at minimum grade may increase to 1.5 feet should sediment build up, roots intrude, or other obstructions in the sewer increase pipe roughness over time. RECOMMENDATION [t is our recommendation that sewers extended from the existing 8-inch sewer pipe stub at the intersection of Akron Avenue and Connemara Trail provide adequate slope to allow surcharging of greater than 1.5 feet above the top of the 8-inch sewer pipe. The City keeps sewers in good condition through their maintenance programs, therefore it is anticipated that the surcharge required for flow equivalent to a 10-inch sewer at minimwn grade would remain around 0.5 feet.
