City Council Memo P 98-2 June 15~ 1998 the area that has been mined and the east area not affected by the gravel mining. Background The property is within the Mineral Extraction Overlay District; a gravel mining operation has been an ongoing process for many years. The mining on the majority of the property is finished and is in the process of going through the reclamation process. Some small scale gravel mining will continue in the southwest corner of the plat on the 30 acre parcel. However, access to the area that will be mined will be off of County Road 21 through the 30 acre lot. Mining traffic will not go through the subdivision. Once the mining is finished the area will go through the reclamation process. Lot Size The A1 district requires a minimum lot size of 10 acres or a density of 4 lots per 40 acres. The applicant selected the density option. In determining the number of lots to be included in this plat the acres of wetlands (8 acres) was subtracted from the total acres (92 acres). The remaining 84 acres could be divided into 8 lots; each of the lot had to have a minimum lot size of 2.5 acres. The 8 lots range in size from 4 acres to 30 acres. Streets The proposed road off of County Road 21 will continue through the plat to the western boundary. The street will be a 32 foot wide rural section with bituminous curbs. The street will terminate in a temporary cul-de-sac with the right-of-way extending to the western edge of the plat. The right-of-way is shown in the most likely location for the future connection based on the site conditions of the parcel to the west. That property is also included in the ME district but has not been mined yet so extension of the road is not likely to happen for some time. For this reason it is suggested the developer either construct the proposed road to the plat's western boundary or provide the city payment to install class v and bituminous at a later date. Septic Systems Providing for septic systems on this site is a unique challenge. Each lot is required to provide suitable room for 2 septic systems, one primary location and one for a replacement system. Typical septic systems need to be located on undisturbed land. Since property was part of a gravel mine, most of it has to be considered disturbed. Lots 7 and 8 have existing houses and conventional septic systems; lot i has not been mined so it should not be
