The total permitted flow at that time was 29,240 gallons per day (GPD) partitioned as 136 single-family residential lots at 210 GPD and 680 GPD for the amenity center (5 GPD per lot for 136 lots). The permitted length of gravity pipe was 8,026 linear feet (LF) and the permitted length of sewer force main was 2,016 LF. The duplex pump station is permitted to operate at 180 gallons per minute (GPM) at 116 feet of head. The entire system except for the sewer infrastructure along Maymont Street and Ginters Park Road was installed and then certified in August of 2007. Approximately 1,734 LF of gravity sewer infrastructure was not installed along those two roads. Those two roads were originally intended for 51 lots — which were not recorded. This revision to Richmond Hills includes a slight land plan change along Maymont Street and Ginters Park Road which allows for the development of 75 lots (24 more single-family residential lots). The increase in sewer flow is 5,160 GPD partitioned as 24 single family residential lots at 210 GPD and 120 GPD for the amenity center (5 GPD per lot for the additional 24 lots). The revised land plan requires 2,573 LF of gravity sewer extension. With 1,734 LF of gravity sewer infrastructure not installed as part of the original permit, the proposed gravity sewer infrastructure increases the total length of gravity sewer for Richmond Hills by 839 LF. The permitted pump station has excess capacity for this revision and no modifications are proposed to it or the sewer force main. Included with this submittal are provided below.
