J� (� � City Engineer/Public Works Director -"�►' �� 1 ATTACHMENTS: Executive Summary-Feasibility Report APPROVED BY: Resolution The City received a petition for public improvements from the owners of the Hawkins Pond area on May 7, 1996. The City received a petition for improvements for the easterly portion of the Baptist Church property on September 3, 1996, and Feasibility Reports for both projects were ordered. Since that time one developer has acquired control over the entire property and the two feasibility reports were melded into one covering the entire property. The resulting Feasibility Report addresses the public improvements necessary for the entire 29 acres which will result in approximately 69 single family homes. The total estimated project cost is approximately 1.28 million dollars. The developer has requested that the City complete the grading for the project which is also included in the project cost. There are three existing single famify homes in the southwest corner of the site which will be provided sanitary sewer service with this project. There will be proposed assessments against these three parcels and a minor amount of funding from the Sanitary Sewer, Watermain and Storm Sewer Core Funds for pipe oversizing, but the majority of the cost will be assessed against the developing property. The funding details are shown on the attached summary as is the proposed project schedule. We have been in contact with the three property owners that will be affected by the property and have provided them copies of the Feasibility Report. Staff recommends that the Gouncil receive the Feasibility Report and set a public hearing for March 4, 1996 to consider the proposed improvements.

Hawkins Pond Street and Utility improvements Rosemou�t, Minnesota Executive Summary City Project No. 275 provides for the construction of sanitary sewer. water main, storm drain, street and site grading improvements in the proposed Hawkins Pond development. This development consists of 69 single-family residential lots,68 of which are assessable in terms of street and utility improvements. The project has been split into two phases. Phase A contains 441ots, and Phase B contains 251ots. Tlus improve�ment is necessary to provide the subject property with municipal utilities and street access. In addition, the improvement is cost-effective and feasible from an engineering standpoint. The improvement would best be constructed as an individual project rather than as a part of another project. This improvement is located in the north half of Section 30, Township 115N, Range 19W. The proposed lots are located in the '�� viciniry of Hawkins Pond which is north of 145th Street West and west of Shannon Parkway. The project includes approximately 3300 lineaz feet of sanitary sewer,44001inear feet of water main, 30001ineaz feet of storm drain, and 38001inear feet of street construction. The total estimated project cost is $1,278,000. Of this total, approximately $1,229,150 is assessable to the Hawkins Pond development, approximately $10,850 is assessable to the three (3) properties along 145th Street West for sanitary sewer construction, and approximately$38,000 will be recovered through City core funds. A-ROSEM9604.02 Page 1 i 4 Spreading the $1,229,I50 over the 68 assessable lots in Hawkins Pond ', yields an aQproximaie assessment rate of$18.076 per lot. Due to the ' different sewer configurations necessary to serve the three (3) lots along ' 145th Street West, the estimated assessments for these lots are not all equal. The assessments for lots 010-36 and 010-45 are approximately '�, $3,�0 each. The assessment for lot 010-43 is approximately �4,350. ! Project construction is scheduled to begin in May of 1997.

This im rovement has been desi nated as P P g City Project No. 275. �� 1.2 Scope The purpose of this report is to determine the engineering feasibility of the project based on a review of the data available, and to make �" recommendations and provide cost estimates for the construction of sanitary sewer,water main, storm drain, street facilities, and site grading improvements. 1.3 Data Available Information and materials used in the preparation of xhis report include: �` � • Preliminary Plat for Hawkins Pond(January, 1997) • Preliminary Grading and Development Plan for Hawkins Pond �� (East Side - October, 1996; West Side - December, 1996) • City of Rosemount Construction Record Drawings � • Comprehensive Sewer Plan Update (June, 1991) v • City of Rosemount Drainage Plan for the West Drainage Area � (May, 1989) • City of Rosemount Comprehensive Water System Plan (October, 1988) � '� • City of Rosemount Assessment/Improvement Policy (March, 1992) • Improvement Policy for Public Infrastructure (July, 1996) � - 2.0 Generai Background � 2.1 Location The project location is shown in Drawing No. 1. The project area is located in the north half of Section 30, Township 115N, Range 19W. �, The project is in the vicinity of Hawkins Pond which is located north of 145th Street West and west of Shannon Parkway. 2.2 Adjacent Property � � Ad�acent land uses are mostly residential. The John Hawkms residence is located in the northeast corner of the development and will become part � of the Plat (Lot 11, Block 2). The Country Hills First Addition development is located to the north of the project area. The Shannon Meadows development is located immediately to the east. Several � existing homes and 145th Street West lie to the south of the project area. Hawkins Pond Street and Utility Improvements A-ROSEM9604.02 '� Rosemount, Minnesota Page 3 �` . � The First Ba tist Church of Rosemount owns the property to the west of P the project area. Currently, some of the Church property is undeveloped. � The Church facility itself is located in the northeast corner of Diamond _ Path and 145th Street West. This report was prepared in close contact - with a representative of the Church, and it utilized a Concept Plan drawn ��; under the Church's direction. �.3 Site Conditions ;� The project area formally consisted of three larger lots owned by Mr. John Hawkins,together with a portion of the Church's property. In the - 1980's the City of Rosemount acquired easements across a portion of �, � these properties for the purpose of creating a storm water storage pond (Hawkins Fond), and for the purpose of constructing trunk sanitary , sewers and sanitary Lift Station No. 4. �' Hawkins Pond drains approximately 271 acres and has an existing normal water level(NWL)of 912 with a high water level (HWL)of 929. � Using a 2-foot freeboard, the City has established a low floor building elevation of 931 in the vicinity of Hawkins Pond. Originally, the pond was designed as an infiltration pond. Therefore,it �` holds very litde water except for periods immediately following a rainfall or snowmelt event. In the past,some of the project area has been used for agricultural purposes. There are several mature oak and pine trees on the �l site. � �, 3.0 Proposed Improvements 3.1 Sanitary Sewer Proposed sanitary sewer facilities are shown on Drawing No. 2. These facilities include the installation of 8-inch sanitary sewers on all streets within the development except for a portion of Dekalb Avenue. This � section of Dekalb Avenue already has a 10-inch trunk sanitary sewer inplace. In fihis area, sanitary sewer services will be cut into the existing trunk sewer as needed. � Currently, the three (3) existing lots located between the proposed development and 145th Street West do not have sanitary sewer service. The street addresses of these lots are 4255 - 145th Street West, 42'75 - � �. 14 Sth Street West and 4355 - 145th Street West. As a art of this , p project, 8-inch sewer mains will be extended south on Davenport Avenue �, and southwest from 144th Street West to serve these lots. ' The sewer main running sauthwest from the west end of 144th Street will be continued westerly to the Church property. This could be used to �' serve future development in the southeast corner of the Church property. 1n addition,the existing sanitary sewer service to the Church building off � Hawkins Pond Street and Utility improvements A-ROSEM9604.02 �' Rosemount, Minnesota Page 4 � �� ,�,' of Dekalb Avenue will need to be relocated to comcide ith the proposed lot con�guration. ; �� Lots 12 through 15 of Block 3 will be served by the existing 8-inch sanitary sewer which runs through the center of these lots to Lift Station , �� No.4. Three (3)existing sanitaty sewer wyes will be utilized for Lots 12 though 14. An additional sanitary sewer wye will be cut into this main for Lot 15. ' '� The proposed facilities also include the extension of 4-inch sanitary sewer , services 15 feet into each lot from the xight-of-way line. Due to the large size of Lot 5,Block 1,there is potential for a future lot division into four , �; lots. Accordingly, four sewer services will be stubbed into this lat. . 3.2 Water Main I �`' Proposed water main facilities are shown on Drawing Na 3. A 12-inch hunk main will be mstalled along Dekalb Avenue, 144th Street West and j Davenport Avenue south of 144th Street West. This will provide a ' �, 12-inch connection between 145th Street West and Country Hills First Addition. A portion of the cost for the 12-inch trunk main will be recovered from City core funds. An 8-inch main will be installed on �\ 143rd Street West and on Davenport Avenue. Lots 12 through 15 of Block 3 will be served from an extension of the , � existing 6-inc�i stub off of 145th Street West. A 6-inch water main will - be connected to the stub and extended easterly and westerly to serve these four lots. ' � The three(3)existing lots located between the proposed development and 145th Street West are currently served with water from 145th Street � West. Accordingly, it is not necessary to provide additional water services to these lots. � The proposed facilities also include hydrants for�re protection and the extension of one-inch services 15 feet into each lot from the right-of-way line. Due to the large size of Lot 5,Block 1,there is potential for a future I, � lot division into four lots. Accordingly, four water services will be �, stubbed into this lot. �, 3.3 Storm Drainage , �` Proposed drainage facilities are shown on Drawing No: 4. The facilities '' include storm drain connections from the proposed streets to Hawkins :� Pond. The storm drain piping varies in size from 12-inch to 42-inch ' � diameter pipe. Catch basins will be installed to collect storm runoff from the street. The �' catch basins will be installed with sumps to collect sediment from the street prior to discharging the storm water into Hawkins Pond. {� Hawkins Pond Street and Utility Improvements A-ROSEM9604.02 Rosemount, Minnesota Page 5 '� � � � Storm drain facilities will be extended to the westerl bound of the Y �'Y development to pick up runoff from the west. Most of the drainage from � the Church property flows east, through the proposed development, to _ Hawkins Pond. � Lots 12 through 15 of Block 3 will not require the installation of storm , drain facilities. These lots will be graded such that storm water runoff will flow north over the ground surface to the pond. The front yard area may drain south to 145th Street West. �� A 12-inch diameter storm drain forcemain will also be installed along the • east side of Davenport Avenue between the southwest corner of Hawkins � Pond and 145th Street West. This will be used in the future when the storm water pumping station is installed near the existing sanitary Lift Station No.4. The storm water pumping station will be used in the future � to limit the high water level (HWL) of the pond during large runoff events. � 3.4 Street Construction The pro�ect mcludes the construction of standard city streets as shown on �� Drawing Nos. S and 6. As shown on the drawings, the streets xo be constructed include 143rd Street West, Dekalb Avenue, 144th Street West,and Davenport Avenue. A 5-foot wide concrete sidewalk will be installed on the south side of 143rd Street West and on the west side of � Davenport Avenue. A concrete valley gutter will be constructed at the � intersection of 145th Street West and Davenport Avenue to facilitate � street drainage. Barrieades will need to be installed at the west end of 143rd Street West. In addition,traffic signs and/or street name signs will be installed as required. �' The proposed street section consists of a 2-inch bituminous wearing course, a 2-inch bituminous base course,a 6-inch aggregate base course, �' and a modified"S"design(surmountable)concrete curb and gutter. This pavement section utilizes a granular subgrade which will be constructed in conjunction with the site grading. The required street grading includes � core excavation of a11 plastic or nonsuitable rnaterials within the roadway area and replacement with granular ar suitable materials. Fine grading, topsoiling,and sodding of the boulevard areas will also be included in the �; City's contract. Street improvements for Lots 12 through 15 of Block 3 will be minimal due to the fact that street access is already provided by 145th Street West. �` As a part of this project,the long driveway connecting the John Hawkins residence with 145th Street West will be eliminated and a new driveway aecess off of 143rd Street West wili be provided to the residence. The i� existing curb drop and pavement on 145th Street West at the Hawkins driveway will be removed and replaced with concrete curb and gutter I � II Hawkins Pond Street and Utility Improvements A-ROSEM9604.02 ' � Rosemount,Minnesota Page 6 � � (design B618). This will be done when the removal of the existing driveway is accomplished. � All street lighting facilities will be constructed, owned, and maintained - by Dakota Electric Association(DEA). The street lights will be provided � as part of the extension of electrical service to the project area. Therefore,construction of street lighting facilities will not be included in the City's construction contract. Provisions for electrical service and � associated restoration will be paid for and coordinated by the developer. Installation of the lighting system will not occur until the City's street construction project is completed. � In accordance with City requirements,a shoebox type lighting fixture will be needed at the intersection of 145th Street West and Davenport Avenue. Lantern type lighting units will be installed in other areas. � The develo er will also coordinate and a for the installation and P PY restaration associated with natural gas,telephone, and cable TV service. � 3.5 Site Grading _ Preliminary or"rough"site grading will be included in the City's contract '� for this project. The site will be graded in general conformance with the Grading Plan. This grading will include topsoil stripping/stockpiling,and excavation and removal of all unsuitable soils from building pad and � street right-of-way areas. Where possible, mature existing trees will be preserved during the site grading. After the excavations are complete, embankments ar"fills"will be constructed with suitable material so that � structure footings and roadway imnrovements can be constructed on a stable subgrade. Salvaged topsoil from the initial stripping operation will then be respread into back yard and boulevard areas. � This project also inciudes the installation of a clay liner in the bottom of the Hawkins Pond basin. The clay material used to line the pond will be � obtained from onsite, provided that suitable clay material can be found during the grading operation. The clay liner will be 18 inches in depth and will be installed to pravide approximately 3 feet of standing water. � This will be done for aesthetic purposes. The addition of 18 inches of liner material to the pond and the creation � of 3 feet of standing water will raise the narmal water level (NWL) of the pond by 4.5 feet to elevation 916.5. This will reduce the effective storage I volume of the pond. Narmally,this would also raise the high water level �. (HWL). Hawev�r,the HWL will remain at elevation 929 due to a future storm water pump which will be constructed at the pand to control the HWL. ,�' If additional excavation material is needed to complete embankment areas and balance the earthwork, 18 inches of material could be removed from the pond bottom prior to placing the clay liner in the pond. � Hawkins Pond Street and Utility Improvements A-ROSEM9604.02 � Rosemount, Minnesota Page 7 � � 3.6 E asements Thirty-foot wide easements for sanitary sewer construction wili be needed � around the perimeter of Lot 11,Block 4. These easements are shown on Drawing No. 2. This will facilitate the construction of a sewer extension and the relocation of the existing forcemain in this area. In addition, � � easements 10 to 20 feet in width will be needed along both sides of the common lot lme between I,ots 6 and 7,Block 4. These will be needed to �'' relocate the Church's sewer ser�ice. Easemerrts, 10 to 20 feet in width, will be needed along both sides of common lot lines where storm drain piping is proposed. These easements �; are shown on Drawing No.4. There may be a need to obtain temporary construction easements for � grading,roadway, and utility construction along the edges of the existing lots located along 145th Street West. The need for these easements will be determined during final design. �, Most of the remaining improvements will be installed in existing p easements or in future street rights-of-way whieh will be dedicated to the City as stipulated in the Developer's Agreement with the City. /� . 3.7 Permits Construction permits will be required from several agencies for this �; project.

The estimates do not include any costs for ., easements which may be required. In addition, street lighting,electrical, gas, telephone, and cable TV costs are not included in the estimates. � The cost estimates are based on bid prices obtained from similar type projects during 1996. The estimates include allowances for contingencies ' (10 percent) and anticipated legal, administrative,engineering, and fiscal � costs (30 percent). A summary of these costs is presented inTable 2. All of the site grading � costs were included inPhase A because the site grading far the entire site should be done as a part of Phase A. It would be difficult to obtain an earthwork balance and accomplish the pond lining if the site grading were �, done separately for each phase. f� Table 2 Summary of Cost Estimates �, Phase Sanit�ry Water Storm Streets Site Total Sewer Main Drain Grading A $143,000 $157,000 $176,000 $260,000 $208,000 $944,000 � � B $110,000 $76,000 $50,000 $98,000 $0 $334,000 A+B $253,000 $233,000 $226,000 $358,000 $208,000 $1,278,000 � 4.2 Assessment Area � All lots within the Hawkins Pond preliminary plat,except for Lot l 1 of Block 2, are subject to assessments to recover the project costs. Lot 11 of Block 2 was previously assessed for City utility and roadway � improvements under other projects. Under normal circumstances, the sanitary sewer and storm sewer � improvements which are part of this project and which provide benefit to the Church would be assessed to the Church. These improvements include the sewer extension to the southeast corner of the Church � property and the storm sewer extension to the westerly plat boundary. However, one of the conditions of the sale of property by the Church to the developer was that the developer would pay the costs of any � assessments to the Church. Accordingly, the Church is not considered part of the assessment area. � i Hawkins Pond Street and Utility tmprovements A-ROSEM9604.02 � � Rosemount, Minnesota Page 9 � � The three 3 existin lots alon 145th Street which will receive sanita ( ) g g n' sewer service are also considered part of the assessment area. � A summary of the parcels included in the assessment area is presented in Table 3. � Table 3 Assessment Area � Hawkins Pond Preliminary Plat No. of Block Lots Assessabie Lots 1 1 1 � 2 1 - 10 10 3 1 -23 23 � 4 1 - 15 15 5 1 - 19 19 � Subtotai 68 � Parceis Along 145th Street West No. of Owner(s) Street P.�.N.

Accordingly, this cost is proposed to be recovered from the City's Water Main Core Facility Fund. For Phase A + B, this amount is estimated to be $19,000. Likewise, the � 12-inch storm drain forcemain along Davenport Avenue is also ` considered a trunk facility, and the cost is pro�osed to be recovered from the City's Storm Drain Core Facility Fund. For Phase A+B,this arnount �; is estimated to be $19,000. Hawkins Pond Street and Utility Improvements A-ROSEM9604.02 � Rosemount, Minnesota page 10 �� . . . . .. . . � � ��I � After the water main and storm drain core costs are subtracted from the II total, the remaining assessable costs are estimated to be $1,240,000 for � Phase A +B.

For the two lots on each side of Davenport Avenue (Lots 010-36 and � 010-45),the estimated additional cost that is necessary to provide sewer service to the lots is$6,500,or$3,250 per lot. This is the cost to extend the sewer main further to the south along Davenport Avenue to serve the � two lots. • For lot 010-43, the estimated cost to run sewer south from 144th Street � West to lot 010-43 is$8,700. However,this extension also serves Lot 11, Block 4. Therefore, only one-half of the cost, or$4,350, is assessable to lot 010-43. � After these assessments for lots 010-36, 010-45, and 010-43 are subtracted from the total assessable cost, the remaining amount is � assessable to the Hawkins Pond development. A breakdown of the assessable costs is presented in Table 5. �� Table 5 Breakdown of Assessable Costs ,N � Hawkins No.of Sanitary Sanitary Sanitary Assessable Assessment Assessable Pond Phase Sewer to Sewer to Sewer to Lots in per Lot in Costs Preliminary Lot 010-36 Lot 010-45 Lot 010-43 P�at Hawkins Hawkins Pond � ' Pond A $918,000 $3,250 $3,250 $0 $911,500 43 $21,198 B $322,000 $0 $0 $4,350 $317,650 25 $12,7d6 �; A+B $1,240,000 $3,250 $3,250 $4,350 $1,229,150 68 $18,076 . � Hawkins Pond Street and Utility Improvements A-ROSEM9604.02 � Rosemount, Minnesota Page 11 � � The assessment er lot for Phase A is hi her than for Phase A + B P g because Phase B has fewer costs associated with it. For example, much � of the sanitary sewer for Phase B is already inplace. Also, Phase B does not include any site grading or pond lining costs. � Since Phase B cannot be completed by itself, the lowest assessment per lot results from constructing both phases of the project together at one time. Phase B has fewer infrastructure needs,and this helps to reduce the � assessment per lot for Phase A+B. 1 5.0 Project Schedule � The proposed schedule for this improvement is listed below.
