Van Milligen, City Manager SUBJECT: Approval of Plans and Specifications for the English Mill Water Main Extension Project DATE: October 2, 2014 Water Department Manager Bob Green recommends City Council approval of the plans, specifications, form of contract and estimated cost of $796,800 for the English Mill Water Main Extension Project. The extension from Stone Valley Drive along English Mill Road will go to North Cascade Road and about 100 feet in both directions on North Cascade Road. The City commissioned an annexation study in 2006. This area was identified as a future area for community expansion and annexation. In 2014, letters were sent to 3,086 residents in Dubuque County within two miles of Dubuque City limits requesting their opinions of City services including water service. The results of the survey are as follows: O 3,086 surveys mailed O 1,200 responded O 239 in support of receiving City of Dubuque water service This project will provide water service to those requesting it along English Mill Road and eventually along North Cascade Road and Highway 20. This is the initial phase of a multi -phase project that will create a looped water system from the English Mill Road entrance of Stone Valley Drive to North Cascade Road to Highway 20 back to Stone Valley Drive and a loop on North Cascade Road back towards the future Southwest Arterial and Cedar Cross Road. In 2014, East Central Intergovernmental Association Director of Transportation Chandra Ravada completed an Economic Impact Study of the Southwest Arterial Corridor. The Southwest Arterial is scheduled for completion in 2019. For the first 10 years after project completion, there is the potential to generate $80 million in property tax revenues, $1.7 billion in economic output, $650 million in labor income, and $1 billion in value added. For those first 10 years the Southwest Arterial is also projected to generate $135 million in state and local taxes and $130 million in federal tax from new economic development, as well as save $30 million because of safety improvements. From 2030 and beyond, this project will also annually generate $15 million in property tax, $304 million in economic output, $24 million in state and local taxes, and $23 million in federal taxes due to economic development, in addition to $3 million in safety savings. The City finds itself in a similar situation as existed in the 1990's when the City was creating 950 acres of industrial parks. The City expended over $20 million to build the industrial parks, including extending utilities to the industrial parks. These utility extensions opened up almost 7,000 acres of land for private development. The extension of these utilities almost 20 years ago has had huge benefits that will pale in comparison to the benefits of the Southwest Arterial area benefits that will be produced. The utility extensions in the 1990's resulted in the creation of over 6,400 jobs, the expansion of 46 local businesses, the attraction of 8 new businesses, and the voluntary annexation of approximately 4,400 acres of property, expanding the geographic size of Dubuque by 28%. From the industrial parks alone, beginning in 2019, taxing bodies will see the inflow of $2 million of property tax revenues per year. The City's commitment to providing utilities to the Southwest Arterial corridor to spur future development is made even more urgent by the recent arrival of the Central Iowa Water Association, who has built a water tower at Swiss Valley Road and Highway 20, with the intent of laying claim to a service territory that includes the Highway 20 and Southwest Arterial Corridor. The Central Iowa Water Association business model includes claiming territory by providing water service, but not always providing sufficient water volume or water pressure to charge all of the fire hydrants or commercial and industrial sprinkler systems in their territory. Therefore, homeowners and businesses may go without adequate fire protection. This limits the amount of development in an area, and what development that does occur may be much more expensive because businesses need to go through the added expense of dry fire suppression systems or they need to boost the water volume and water pressure to serve their sprinkler systems at great extra expense. North of Ames, Iowa, the Xenia Rural Water System claimed a territory and the developer had to agree to pay almost $3 million to Xenia in order to be allowed to access the higher quality water services from Ames. These rural water systems can command such high buyout prices because their territories, once they claim the area by running a water line, are federally protected. The only two ways the City of Dubuque can protect the development potential of the Southwest Arterial corridor and the Highway 20 corridor, and the value of the land for 2 the private property owners, is by either annexing the area or by extending City utilities to the area before Central Iowa Water Association. With the second lowest water rates of the 10 largest cities in the State of Iowa, the City of Dubuque is well positioned to implement these water extensions. I concur with the recommendation and respectfully request Mayor and City Council approval. Mic ael C.

DISCUSSION The extent of the work involved in the City of Dubuque, Iowa English Mill Road Water Main Extension 2014 project consists of the construction of a 12 inch water main from the intersection of Stone Valley Drive and English Mill Road to North Cascade Road along English Mill Road. The water main along with the proposed booster station will create a new pressure zone (Zone 7) in the City of Dubuque distribution system. The project consists of approximately 6,400 LF of 12 inch water main, including 865 LF of 12 inch DIP and 5,500 LF of 12 inch PVC water main. The project also includes various water main appurtenances including: fittings, resilient seat gate valves, fire hydrants, mechanical and push -on joint restraints, etc. Rock excavation is anticipated to be encountered for the water main installation. Erosion control including silt fence, rolled erosion control product, topsoil removal and replacement, and seeding. Traffic control is included in the project to maintain a safe work site for both the Contractor and the public. Coordination with two other projects in the same general area associated with the project will be required. Engineer's opinion of Probable Cost: $595,000 BACKGROUND As part of the City's Master Plan for growth, the ability and costs to extend city services to properties currently in unincorporated areas of Dubuque County need to be evaluated. To assist in this process, public input was sought. Letters were sent to 3,086 residents in Dubuque County requesting their opinions of city services including water service. The results of the city service survey are as follows: 0 0 0 3,086 surveys mailed 1,200 responded 239 in support of water service In review of these survey results, the city should proceed to provide water service to those requesting it along English Mill Road, Cascade Road and eventually along Highway 20. This is the initial phase of a multi -phase project that will create a looped water system from the Highway 20 entrance of Stone Valley Drive to English Mill Road to Cascade Road to Highway 20 back to Stone Valley Drive. In discussions with Public Works Director, Don Vogt we determined that as part of the proposed Dubuque Landfill Facility improvements to take place in the near future, we should provide the new facility with city water. The English Mill improvement requests will support the current and future water service needs to this area. I have provided a map as an attachment for your review showing this proposed improvement and future improvements in this area.

DISCUSSION English Mill Pump Station Design: Pump station is designed to supply water to the 7th pressure zone (N. Cascade Road area). Water source will come from the 3rd pressure zone (S.W. Arterial area) and the 4th pressure zone (HWY. 20 area / West Industrial Park). Water Treatment plant operator will have the choice (from the Treatment Plant through the SCADA system {remote control}) to select which pressure zone is needed or both zones pending system demand. In addition, water could also be pumped from the 3rd pressure zone (S.W. Arterial area) to the 4th pressure zone (Hwy. 20 area / West industrial Park) after completion of the S. W. Arterial water main (either from the existing 12" diameter water main on N. Cascade Road or 16" water main on Crescent Ridge. Pump station was designed and bid to have the internal and exterior piping for the above process installed during the actual construction of the pump building. No pumps are planned to be installed on the 3rd pressure internal piping until the 3rd pressure zone water main is installed on and from the S. W. Arterial. Temporary back up water (during emergencies) could be supplied from the 4th pressure zone (HWY. 20 area / West Industrial Park) to the 3rd pressure zone (S.W. Arterial area) through the use of a pressure sustaining valve connected between the two zones when the piping is completed. Page 1 of 2 With the completion of the 7th pressure zone (N. Cascade Road area) water main. At the connection point on both HWY. 20 near the landfill (4th pressure zone) and N. Cascade Road near the intersection of S. W. Arterial (3rd pressure zone) a pressure sustaining valve can be installed to provide temporary back up water (during emergencies) from the 7th pressure zone to the 4th pressure zone and 7th pressure zone to the 3rd pressure zone respectively. This provides the City a second option as this is also provided at the English Mill Pump Station between the 3rd and 4th pressure zones. While not part of the current plan, the City could add two additional pump stations at these pressure sustaining valve locations that improves the flexibility of the crossovers between the 3rd, 4th and 7th pressure zones. Advantages of the English Mill Pump station: Multifaceted pump station having the sources and ability to supply multiple pressure zones. Creating a third supply source to the 4th pressure zone (HWY. 20 area/West Industrial Park). Located on the south end of the 4th pressure zone approx. 6 1/2 miles away from the existing and only water storage tank in the 4th pressure zone (J. F. Kennedy Road Water Tower). Could assist fire demand in the West Industrial Park which could delay for a period of time the construction of the second water tower storage tank in the 4th pressure zone. Please note that the 3rd pressure zone water main (S.W. Arterial area) needs to be completed before the City gains this benefit. See attachments for diagrams.
