water management program is in place in Ramsey (Ramsey, 2018b). The storm sewer system is currently in good condition and the City has a maintenance program in place to keep the system operating properly. The City will rely on their existing surface water management program to address issues related to surface water. Therefore, additional measures to address surface water in this Plan are considered to be unnecessary. C1.4 Water Quantity Data Elements Surface water and groundwater quantity are discussed in this section. C1.4.1 Surface Water Quantity As discussed above, the surface water features in the DWSMAs include Jeglens Marsh and some small ponds. The City Code requires a drainage plan for new developments if the direction, quantity or quality of drainage of a site will be altered during development. Any changes must conform to the City's comprehensive surface water management plan (Ramsey, 2018b). The Minnesota Permitting and Reporting System (MPARS) database indicates there are no surface water appropriations in the Ramsey DWSMAs. The City is not aware of any current water -use conflicts that impact surface water quantity in the vicinity of the DWSMAs. Therefore, measures in this Plan to address surface water quantity issues are considered to be unnecessary. C1.4.2 Groundwater Quantity The Ramsey municipal water supply system currently includes seven primary water supply wells and one seasonal -use well. Under MDNR Appropriation Permit No. 1985-6005, the City of Ramsey currently has a permitted annual groundwater appropriation of 850 million gallons per year (MGY). The permitted instantaneous total pumping rate for the Ramsey system is 8,200 gallons per minute (gpm) or approximately 11.8 million gallons per day (MGD). The projected water use (i.e., pumpage) used to delineate the Ramsey WHPAs and DWSMAs was 949,205,000 gallons per year (MDH, 2018). Ramsey was incorporated as a city in 1974. Between 1970 and 2000, the population of Ramsey increased from 2,536 to 18,510. The 2010 census counted a total of 23,668 people in Ramsey (an increase of approximately 28% over the 2000 population). In 2017 the City's estimated population was 25,581. It should be noted that the City's water supply system does not serve the entire population of Ramsey. In 2017the estimated population served by the municipal water supply system was 13,720. The City's draft Water Supply Plan (Ramsey, 2018a) projects that the City's water supply system will serve 13,921 people in 2020 and 22,987 in 2030. The draft Water Supply Plan projects the City's total population in 2030 will be 33,350. C-8
