Receive Feasibility Report/Set Public Hearing, Biscayne Avenue Improvements, City Project #249 j " CITY OF ROSEMOUNT EXECUTIVE SUMMARY FOR ACTION CITY COUNCIL MEETING DATE: July 19, 1994 AGENDA ITEM: Receive Feasibility Report/Set Public AGENDA SECTION: Hearing, Biscayne Avenue Improvements, City Project #249 Old Business PREPARED BY: Bud Osmundson AGENDA ����/� � �r � City Engineer/Public Works Director iY! ( ATTACHMENTS: Resolution, Feasibility Report APPROVED BY: Attached is the feasibility report for Biscayne Avenue Improvements from County Road 42 on the south to approximately 500 feet north of the railroad tracks north of 145th Street. Proposed improvements include storm drain, sanitary sewer, watermain and street construction. Previously the City had received a petition from the Military Affairs Department of the State and the CMC Heartland Partners for improvements on Biscayne Avenue. The "Executive Summary" within the report summarizes the proposed improvements, costs and funding sources. The total project will include approximately 4,000 feet of street construction, 850 feet of sanitary sewer, 4,000 feet of watermain and 5,300 feet of storm drain improvements. The total estimated cost of the project is approximately 2.4 million dollars. Of that #otal, 1 .3 million would be assessed to benefiting properties, 5280,000 would be obtained from State Aid funding for street improvements, 5172,000 would be obtained from the Watermain Core Fund, 5609,000 from the Storm Water Utility/Storm Core Fund and $8,000 from the Sanitary Sewer Core Fund. The report identifies that an additional 587,000 is attributed to the Watermain Core Fund for a Trunk facility through the CMC proposed plat. This project could be broken into two separate projects or divided in some manner to provide the necessary irnprovements for the National Guard OMS facility and for CMC's preliminary plat. The OMS facility portion which they have petitioned for would be the extension of sanitary sewer� watermain and storm sewer north of the railroad tracks from existing lines in Biscayne Avenue. CMC's request is to have the roadway paved from CSAH 42 to approximately 1 ,000 feet north to allow them to have a connection to Biscayne, which was a requirement by the City Council for their preliminary plat approval. Staff recommends we have a public hearing for the entire project. The project could then be divided into segments for the necessary construction in 1994 for the OSM facility and CMC with the remainder being constructed in 1995.

This improvement is located on Biscayne Avenue from CSAH 42 on the south to approximately � 1,500 feet north of 145th Street. The total length of the proposed street is about 4,000 feet. This segment of Biscayne Avenue is on the Minnesota State Aid Street(MSAS)System,and therefore, must meet the applicable design standards to qualify for MSAS funding. � The project includes a roximatel 850 feet of sanita sewer,4,800 feet of water main,5,300 feet PP Y rY of storm drain and 4,500 feet of street and sidewalk construction. � Street lighHng facilities will be designed, installed and maintained by NSP. Likewise, the C.P. Rail track crossing will be designed and installed by C.P. Rail. The costs for street lighting and � ; the track crossing are included in the estimates. The total estimated cost of the project is $2,380,530 including contingencies, overhead and � temporary construction easements. Of this total, $1,311,640 will be assessed to benefitting properties,$279,950 will be obtained from MSAS funds,$171,890 will be obtained from the Water Main Core Facility Fund, $609,000 will be obtained from the Storm Water Utility Fund/Storm Water Core Fund, and $8,050 will be obtained from the Sanitary Sewer Core Facility Fund. � ' In addition to these costs, the City will be responsible for the oversizing costs of the trunk watermain which is proposed to be installed through the Eastbridge Development. This trunk � main will be installed by the developer under a separate project. The City's share of this work is estimated to cost $87,300. � The project is scheduled to begin in the fall of 1994 and be completed in 1995. As a minimum, ' CMC Heartland Partners would like to have Biscayne Avenue paved between CSAH 42 and Bloomfield Path in 1994. Also, the Army National Guard would like to have utilities extended � to their site in 1994. The estimated cost to complete this much of the project is $937,900. � � � � � � � �' � July 19, 1994 � � � Preliminary Repor� � • Biscayne Avenue Improvements � Rosemount, Minnesota � � 1.0 introduction 1.1 Authorization �� On May 17, 1994,the City Council of the City of Rosemount,�pon petition by the developers(CMC Heartland Partners and the Army National Guard)authorized the preparation of a preliminary report � for construction of utilities and streets on Biscayne Avenue. This project has been designated as City Project Number 249. � 1.2 Scope The purpose of this report is to determine the engineering feasibility of this project based upon a review of the data available, � and to make recommendations and to provide cost estimates for the construction of sanitary sewer, water main, storm sewer, and street facilities on Biscayne Avenue. � 1.3 Data Available Information and materials used in the preparation of this report � include: 1.

Section 29 Drainage Study Quly, 1994). � 2.0 General Background 2.1 Location � The project location is shown on Drawing No. L The proposed street and utility improvements are located on Biscayne Avenue from CSAH 42 on the south to approximately 1,500 feet north of � 145th Street. In addition, there will be a segment of storm drain required along the north side of CSAH 42 west of Biscayne Avenue. , � 2.2 Adjacent Property Land uses along the proposed project include agricultural, � residential and commercial/industrial uses. At this time, development on the west side of Biscayne Avenue is limited to the Knutson Recycling site located just south of the C.P. Rail crossing. � Developments on the east side of Biscayne Avenue include single family homes fronting off of Biscayne Way and the Dakota County � Preliminary Report A-ROSEM9406.00 Rosemount, Minnesota Page 2 � �' � � HRA townhome units. 'The Dakota County Maintenance Shop is � also located on the east side of Biscayne Avenue. There are several proposed developments adjacent to the project. � CMC Heartland Partners is proposing the Eastbridge Development on the west side of Biscayne Avenue between CSAH 42 and 145th Street. This development will be constructed in four � phases with an estimated192 single familyresidential lots,l4 acres of cluster homes and 8 acres of commercial development. � Another proposed development will be located north of the C.P. Rail crossing. This is the Army National Guard Organizational Maintenance Shop which will encompass about 25 acres of land. This facility will serve as a vehicle maintenance hub which.will � generate most of its activity on the weekends. The future land use plan contained in the City's Comprehensive � Plan calls for the remaining undeveloped iand along Biscayne Avenue to be either residentiaI or business park. � 2.3 Site Conditions The existing roadway has a 30 foot wide gravel surface along the entire length of the project. The depth of gravel and the suitability � of the underlying soils is unknown at this time. The right-of-way width is 33 feet on each side of the centerline. The roadway has a rural section with ditches on both sides. The existing terrain is � flat. However, there is an overall grade of about 0.5% from the north end of the project to the south end. Biscayne Avenue is currently signed as a two-way stop at the following intersections: � CSAH 42, 145th Street and the railroad. There is inplace sanitary sewer from CSAH 42 to the C.P. Rail � Crossing. In addition, there is inplace water main from 145th Street to the railroad. � 3.0 Proposed Improvements 3.1 Sanitary Sewer � Proposed sanitary sewer facilities are shown on Drawing No. 2. These facilities include the northerly extension of an 8-inch sewer from the inplace main at C.P. Rail to the northerly boundary of the � National Guard site. A subsurface crossing will be required beneath the C.P. rail tracks. � Preliminary Report A-ROSEM9406.00 Rosemount, Minnesota Page 3 � � ' � � Sanitary sewer mains are already inplace frorn the railroad tracks � southerly to CSAH 42. The existing 8-inch rnain located north of 145th Street is owned by the City of Rosemount, and the existing 12" main located south of 145th Street is owned by the � Metropolitan Waste Control Commission (MWCC). The manholes on these mains will need to be partially � reconstructed due to the proposed street grade change. The manhole castings will be lowered approximately 2 to 3 feet. One of the existing manholes will be removed and relocated to align � with a proposed street in the Eastbridge Development. The proposed developments to be served by these sewer � improvements are inside the Metropolitan Urban Service Area , (MIJSA)and are tributary to the Rosemount Wastewater Treatment Facility. � 3.2 Water Main Proposed water main facilities are shown on Drawing Na 3. These facilities include a 16-inch trunk main hom the south side � of CSAH 42 to 145th Street,and a 12-inch extension northerly�rom : the inplace main at the railroad to the northerly boundary of the National Guard site. Subsurface crossings will be required beneath � CSAH 42 and the railroad tracks. A separate 16-inch trunk main will be installed by CMC through � the Eastbridge Development which will link the Rosemount Business Park and Biscayne Avenue. A stub will be extended westerly near Blackwell Court for the purpose of connecting to the � trunk main. This 16-inch connection between the Business Park and Biscayne Avenue is recommended in the 1988 City of Rosemount Comprehensive Water System Plan. � The existing 12-inch water main between 145th Street and the railroad will need to be lowered several feet to provide adequate � cover below the revised road grade. The inplace 8-inch water main crossing at Biscayne Way and the inplace 12-inch water main crossing at 145th Street will also need to be lowered for the same reason. Fire hydrants and 6-inch service stubs will also be � installed at appropriate locations along Biscayne Avenue. � 3.3 Storm Drainage Proposed storm drainage facilities are shown on Drawings 4 and 5. These facilities include a trunk storm drain along the entire � Preliminary Report A-ROSEM9406.00 Rosemount, Minnesota Page 4 � � � � length of Biscayne Avenue as well as an outlet westerly from I', � Biscayne Avenue#o a pond in the Eastbridge Development. The ' trunk main ranges in size from a 27-inch pipe at the northerly end to a 48-inch pipe at the downstream end. A subsurface crossing will be required at the C.P.Rail tracks. � The trunk main will begin at the National Guard facility and � continue southerly along Biscayne Avenue to a point near the north ditch of CSAH 42. From this point, the trunk main will follow the narth ditch of CSAH 42 westerly ta a proposed storm � water pond in the Eastbridge Development. This storm water pond is part of the Business Park ponding chain. An additional subsurface crossing under CSAH 42 will be included in this project , to convey storm water to the south. � The drainage facilities include manholes to facilitate maintenance of the mains, and catch basins with built-in sumps. The sumps � will be included for sedimentation purposes in accordance with the City's Storm Water Management Ordinance. � The proposed trunk main will be designed to collect and convey storm water flowing in the street as well as water coming to the street from areas outside the right-of-way. The area to be drained � by the proposed trunk main-is shown on Drawing No. 6. This drainage area closely follows natural drainage patterns except where the .natural patterns are' proposed to be changed• by ,� development. A separate drainage study was done on the drainage area � referenced above and on additional areas immediately to the west and south. This study was entitled "Section 29 Drainage Study'` and contains more detailed information on drainage boundaries, � storm water ponds, and storm drain sizing. The Section 29 Study encompasses Biscayne Avenue as well as the Eastbridge Development and the Business Park area. The study was done � concurrently with this report due to the broad drainage issues which affect Biscayne Avenue. 3.4 Street Construction � The proposed street for Biscayne Avenue is 52 feet wide as shown on Drawing No. 7. The street design includes a barrier #ype � concrete curb and gutter (B618) and an 8 foot wide bituminous trail on the west side of the street. The proposed pavement section consists of 5-1/2-inches of bituminous pavement over 8-inches of � Preliminary Report A-ROSEM9406.00 Rosemount, Minnesota Page 5 � � � � aggregate base. In addition, a 24-inch deep layer of granular � borrow will be installed beneath the aggregate base. The boulevard areas will be sodded. This design meets the MSAS standards for a low density 41ane arterial with no parking on both � sides. The elimination of ditches and the construction of an urban street � section will necessitate a change in the grade of the existing street. Except for the connection to CSAH 42 and the intersection with C.P.Rail,the street grade along the entire project is proposed to be � lowered approximately 2-1/2 feet. This is necessary to allow drainage to enter the street from areas outside of the right-of-way. This grade change will also need to be made for a short distance on cross streets such as Biscayne Way and 145th Street. In � addition,existing utilities in some parts of the project will need to be lowered in order to maintain adequate cover after construction. � Based on a proposed width of 52 feet, Biscayne Avenue could be striped for two lanes in each direction or for one lane in each direction with a continuous center turn lane. Either way, � dedicated right turn lanes will be needed on Biscayne Avenue at 145th Street and at CSAH 42. In addition, a dedicated right turn lane will be required for westbound CSAH 42 traffic at Biscayne � A�enue. Striping and signing will be included in the City's construction cantract. Conduit for future traffic signals will be installed at 145th Street. Until 145th Street is reconstructed � between T.H. 3 and CSAH 42, the intersection with Biscayne will remain as a two-way stop on Biscayne. � 3.5 Street Lighting Street lighting facilities will be constructed and maintained by NSP � under an agreement between the City and NSP. Therefore, construction of street lighting facilities will not be included in the City's construction contract. However,NSP's costs for construction � will be invoiced back to the City. Accordingly, costs for street lighting facilities have been included in the estimated street costs. 3.6 Railroad Crossing � A railroad crossing and traffic control facilities will be installed at the C.P. Rail track. All crossing work will be done by C.P. Rail under an agreement between the City and C.P. RaiL Therefare, � construction of the rail crossing will not be included in the City's construction contract. The cost for this work will be invoiced back � Preliminary Report A-ROSEM9406.00 Rosemount, Minnesota Page 6 � � � � to the City. Therefore, the cost for the crossing work and traffic � control facilities has been included in the estimated street costs. 3.7 Easements � Ultimatel , the existin 66 foot wide ri ht-of-wa is ro osed to Y g g Y P P be widened to 100 feet. Acquisition of the additional 17 feet on each side of the road is proposed to occur concurrently with �' development through dedication. The additional right-of-way will be obtained from the Eastbridge Development and the Army � National Guard Development prior to construction of Biscayne Avenue. Right-of-way acquisition in other areas will not be complete until development or re-development occurs in those areas. Until that time, temporary construction easements will be � obtained as needed to facilitate construction beyond the existing 66 I foot right-of-way. The estimated cost of temporary construction , easements has been included in the street costs. � 3.8 Permits � Construction perxnits will be required from several state agencies as well as from the County and the railroad. The following table summarizes the permits which may be required for this project. �' � � 5,c .�"3" . . . .����.����� � Minnesota Pollution Metropolitan Minnesota Control Waste Control Department � Agency Commission of Health Dakota (MPCA) (MWCC) (MDH) C.P.

The residential equivalent improvement is what is needed to serve only the subject property with no oversizing. Many improvements � need to be oversized to serve nearby areas which may develop in the future. The City has separate Core Facility Funds for the oversizing of sanitary sewer, watermain and storm drainage. � Far sanitary sewer, the cost to reconstruct existing manholes is ronsidered a City` core facility cost because this cost is not � assessable. With standard contingencies and overhead allowances, the estimated sanitary sewer core cost is $8,050. � For watermain, the cost of larger pipe diameter required to serve property outside a development is considered to be a City core facility cost. In addition, the cost to lower existing watermain is considered a core facility cost because it is not assessable. With � standard contingnencies and overheaed allowances, the estimated water main core cost is $171,890. � Preliminary Report A-ROSEM9406.00 Rosemount, Minnesota Page 10 � � � � The City will also be responsible for an estimated $87,300 for watermain oversizing in the Eastbridge Development. However, � this amount is not listed in the summary tables because it is not part of this project. For storm drainage facilities, the cost of larger pipe diameter � required to serve property outside a development is considered to be a City core facility cost. In this case, the cost of the trunk main I without catch basins is considered to be a storm water core cost. � � With standard contingencies and overhead allowances, the ' estimated storm water core cost is $609,000. This cost can be recovered from the Storm Water Utility/Storm Water Core Fund. � : 4.3.3 MSAS Fund Since Biscayne Avenue is on the Minnesota State-Aid Streefi � (MSAS) system, the project is eligible for MSAS funds. Although most of the street costs and some of the storxn drainage costs are eligible for MSAS funds, the City's current MSAS Fund balance is � limited. Accordingly, the amount to be recovered from the MSAS Fund was determined by subtracting the total assessments and the total contribution of the core funds from the total project amount. � The remaining amount which is not covered by assessments or core funds is proposed to be recovered from MSAS Fund. � � With standard contingencies and overhead allowances, the estimated amount to be recovered from the MSAS Fund is $279,950.

This project has been designated City Project No. 259. � 1.2. Scope - This project provides for the construction of st4rrn drain � improvements required to provide an outlet for Schwarz Pond. The City has received a petition from Independent School District N4. 196 for a public improvement which would control the water elevation of Schwarz � Pond. � In 1992 OSM completed a feasibility report for the Armory Storm Drainage Improvement (City Project No. 238). That repart discussed the improvements to the Armory Site Pond (Pond SCH 153) and praposed a � future storm drain outlet for Schwarz Pond (Pand SCH 151) through the Armory Site to Erickson's Pond (Pond ERN 190), located north of City � Hall. At this time, a portion of the storm drain improvements that were recommended in the Armory Storm Drainage improvements Feasibility Report have been constructed. This report addresses the improvernents � necessary to provide a storm drain outlet for Schwarz Pond. � 1.3. Data Available-Information and materials used in the preparation of this report include: � • City of Rosemount Record Plans _ • City of Rosemount Aerial Photo/Topography Maps r • City of Rosemount Drainage Plan - West Drainage Area - May, 1989 � • Feasibility Report-Arrnory Storm Drainage Improvernents- , City Pro�ect Na 238 , 1.4. Background - Schwarz Pond is located in Section 30, west of State Trunk Highway 3 (STH 3} and north of Rosemount High School (see Location � Map, Figure No. 1, in the Appendix of this report). The southern portion of Schwarz Pond is located on the Rosemount High School property � � OSM Project Na 5498.00 Page 1 � � t approximately 35 feet from the e�cisting high school building whieh has a � low entry elevation of 930.2. � Schwarz Pond is delineated as a land-locked pond in the City of Rosemount Drainage Plan - 1989. In the past, critical storm events have � produced flooding conditions at Rosemount High SchooL � Schwarz Pond SCH 1S1 � Normal Water i.evel 921,5 �N�) � High Water Level 935.0 (HWL) � Storage Volume 140 Ao-Ft � Four draina e irn rovement alternatives were reviewed in the Armo � P rY Storm Drainage Improvement Feasibility Report. The recommended � improvement alternative for the Armory Storm Drainage project was to constxuct an 8.4 Ac-Ft. pond on the Axmory site with a future outlet to ' ' Erickson Pond (Pond ERN 190). After the outlet for the Armory Site Pond is constructed, the pumped outlet for Schwarz Pond into the Armory Site Pond could then be constructed. � At this time, the following storm drainage improvements have been � constructed in the Schwarz Pond Drainage District: • Storm drains within Armory site � • 8.4 Ac-Ft.storm drainage pond on the Armory site (adjacent to STH 3) � • 18-inch diameter storm drain outlet from Armory Site Pond �; to the east side of STH 3 (currently bulkheaded) � � OSM Project No, 5498.00 Page 2 � � � The City of Rosemount Drainage Plan - 1989, aLso delineates Erickson Pond as a landlocked pond. As is the case with Schwarz Pond, the HWL in Erickson Pond will continue to rise as development occurs. In the � future,a storm dra.in outlet for Erickson Pond will need to be constructed or flooding in its drainage area will occur. The City of Rosemount � Drainage Plan - 1989 lists the data for Erickson Pond as follows: Erickson Pond � ERN 190 � NWL 920.8 HWL 94Q.7 � Storage Voiume 110 Ac-Ft. � Further analysis of the Erickson Pond and surrounding drainage districts has led to revising the data for Erickson Pond (see revised pond data in � Section 2 of this report}. 2. PR4POSED IMPROVEMENTS � 2.1. Storm Drains - The following improvements are proposed as part of City ' Project No. 259. • Construct a storm drain lift station capable of pumping 5.8 cfs at � Schwarz Pond. The lift station would pump to the east and discharge into the existing storm drain catch basin located on the � west edge of the Armory site (approximately 1,200 lineal feet of 12- inch D,I.P.). � • Extend the existin 18-inch diameter ravi storm drain outlet for g g LY the Armory Site Pond to the east to Erickson Pond (approacimateiy � 1,SOO lineal feet of 18-inch RCP). If the storm drain outlet for the Armory Site Pond is not constructed and the stormwater lift station � at Schwarz Pond begins pumping, in less than two hours the Armory Site Pond will become full and will overflow to the west � � OSM Project No. 5498.00 Page 3 � � � and back into Schwaxz Pond. This could result in flooding at the Rosemount High School. � The propased improvements are shown on Figure No. 2 in the Appendix of this report. When the above-described improvements are constructed, � the pond data for the affected gonds is listed as follows: � Schwarz Pond Armory Site Pond Erickson Pond SCH 151 SCH 153 ERN 190 � NWL 921.5 953.0 92Q.8 HWL 928.5 960.5 944.6 � Storage Volume 73.Q Ac-Ft 8.9 Ac-Ft 240 Ac-Ft � � As stated in Section 1.4 of this report, Erickson Pond is landlocked and the water elevations in this pond will continue to rise as development occurs. In order to control the water elevations in Erickson pond, a storm � drain outlet will need to be provided. The HWL listed above for Erickson Pond assumes that when the critical rainfall event occurs in the watershed, � the water elevation in Erickson Pond is at its NWL - 920.8. A minor amount of grading at Erickson Pond will also be required as part � of City Project No. 259. � A �ravity storm drain outlet for Schwarz Pond was considered, however, the deep excavation (over 4Q feet) made this alternative cost prohibitive. � 2.2. Permits-Permits will be required for this project from Mn/DQT for work witliin the STH No. 3 right-of-way. � 2.3. Right�f-Way and Easements-T`he proposed construction on the west side of STH No. 3 will be located on City or the Independent School District � No. 196 (ISD No. 196) property. The proposed forcema.in will be constructed along the cartway alignment. On the east side of STH No. 3, � � OSM Project No. 5498.00 Page 4 � � ' a permanent easement will need to be obtained from one of the following paxcels: � 34-02010-014-88 NHD Rosemount Woods Assoc. Limited Partnershi P 34-03700-010-00 Alliance Landscaping � Approximately 1.05 acres of permanent easement will need to be acquired , for the project on the east side of S'TH No. 3. Final design will determine the e�.ct location of the easement to be acquired. � Temporary construction easement swill also be required along the project route. Temporary easements will need to be acquired from ISD No. 196 � and from the property on the east side of STH. No. 3. 3. FINANCING � . 3.1. Cost Estimate-A detailed cost estimate can be found in the Appendix of � this report. The following estimate is based on 1994 construction costs and includes a 10% contingency factor and related administrative costs. The administrative costs are estimated at 30% and include legal, � engineering, interest, and other administration. � The total estimated project cost for City Project No. 259 is: � $344,000 (including easement acquisition) 3.2. Assessments - The proposed improvements provide benefit to the entire � Schwarz Pond Drainage Area. Therefore, it is proposed to assess the improvements on an area-wide basis. Figure No. 3 in the Appendix of this � report shows the assessment area for this project. Also included in the Appendix of this report is the preliminary assessment roll for the project. , The total area of the benefitting properties is 15,078,161 square feet(346.1 acres). T"he assessment rate for the project is calculated as follows: i $344,000/15,078,161 Sq. Ft. _ $0.023/Sq. Ft. � ($994/Ac.) � OSM Project No. 5498.00 Page 5 ' � ' Of the total$344,0(�to be assessed, the portion of the project assessments that will be paid by the Trunk Storm Drain Fund is estimated at$127,929. , 4.
