<br />4.2 Water Resource Management Agreements <br />Storm sewer maintenance agreements are in-place between the City and <br />both MnDOT and Ramsey County. <br />The agreement with MnDOT is for the Snelling Avenue reconstruction <br />project through Falcon Heights, and states that the City is responsible for <br />storm sewer facilities located outside the Snelling Avenue rights-of--way. <br />The City is therefore only responsible under this agreement for the <br />Snelling Avenue East and West Frontage Road storm sewer systems and <br />their connections to the Snelling Avenue trunk line. <br />The agreement with Ramsey County states that the City has a <br />responsibility for maintaining the trunk storm sewer lines and <br />connections from City storm sewer systems for all County Road <br />segments throughout the City. <br />4.3 Land and Water Resources Inventory <br />The land and water resources inventory is a summary of information <br />provided in the Capital Region Watershed District Plan and the Rice <br />Creek Watershed District Plan. <br />4.3.1 Climate and Precipitation <br />The climate of the City of Falcon Heights is similar to the overall Seven <br />County Metropolitan Area. The climate consists of fairly short summers • <br />with an average temperature of 70 degrees F, and snowfall covers much <br />of the ground from late fall to early spring, with an average winter <br />temperature of 17 degrees F. Average annual precipitation is 28.32 <br />inches, including approximately 46 inches of snowfall. <br />30-year average temperature and precipitation for the Minneapolis-St. <br />Paul Airport Weather Station are summarized in Table 3 on the <br />following page. Data obtained within the CRWD Plan are available from <br />the University of Minnesota - St. Paul Campus Weather Station and the <br />Office of the State Climatologist. <br />Table 4, on the following page, illustrates the probability of a rainfall <br />event occurring in any given year. The recurrence interval is a measure <br />of the probability of occurrence of the storm event. For example, a <br />rainfall event of 5.9 inches has a 1% probability of occurring in any <br />given year which is expressed as once in every 100 years, the 3.6-inch <br />rainfall event has a 20% probability of occurring in any given year, <br />which is expressed as once in every five years. <br />Table 3 -Minneapolis-St. Paul Weather (30 Year Record) • <br />TComprehensive Plan UpdateT <br />City of Falcon Heights <br />AFAL000701.00 <br />Page 20 <br />
