Page 15 Special Assessments Policy rate. The assessment rate is established by resolution and is updated periodically. Currently the Water Trunk, Source and Storage fee is $2,000 as of January 1, 2002 and will increase $100 per year each year until 2017. Commercial/industrial Property - charged at a rate of $2,000 per unit. The number of units to be charged is based on sewer usage. This is governed by the Council Environmental Services (MCES) "Reserve Capacity Charge Manual" (i.e., if the usage is such that property would be charged eight SAC units, the Water Trunk, Source and Storage fee would be charged at a rate for eight units.) 3. On vacant land or empty lots, the fee is not assessed as part ofthe project but is collected as a connection fee along with the building permit. The fee on commercial properties is dependent upon anticipated usage based upon the MCES Reserve Capacity Charge Manual (Iatest edition.) V. STORM SEWER IMPROVEMENTS A. Definitions 1. Storm Sewer System Network of open channels and pipes, ranging in size from 12" to approximately 66" for conveyance of surface runoff from rainstorms, have an estimated intensity and duration based upon 5 to 10-year design storm for lateral system and a 100-year, 24-hour design storm for trunk. The City utilizes a minor and major storm sewer system in a drainage area. The minor storm sewer system is the lateral piping that conveys the water from the streets to the holding ponds. When the water inundates the minor system, the major system, i.e., streets and ditches, would convey the water within the drainage area to the holding pond(s). For this method to work, the drainage area has to be shaped like a saucer. Future developments would not be allowed to have more than one foot of water in the center of the streets before the water would flow overland from the local low area by the major storm sewer systems to the holding pond(s) within the drainage area. This would not only prevent basements from being flooded, but would also allow safety vehicles to operate during the design storm. 2. Storm Sewer Service District The service district is the total area for which the system is designed and which will benefit from the construction. The extremities of the district usually conform closely with the natural or proposed watershed lines. Runoff from areas beyond the watershed line will drain into some other district.
