The existing subdivision (Morger Smith Subdivision) was established around the 1900's and the grading for the subdivision will never be able to apply to current drainage and grading standards. The lots are typically configured as a"Type C" grading which allows for the drainage from the front of the lot to flow towards the rear of the lot. The existing lot lines on the north and south are at 1.25% and 1.46%, respectively. These are existing established lot lines with an alley running along the north and east sides of the property. Grades cannot be changed without impacting other residences adjoining the alleys. The proposed structure was located to be out of the defined floodplain and maintain the front and side yard setbacks. The closest corner of the proposed structure to the floodplain is 0.54' from the floodplain demarcation line. In addition, the top of foundation elevation of the new structure, was set at 5,024.8 which is a minimum of 2.0' above the floodplain elevation. It is also intended to have an approximate 9 1/z" of foundation reveal which provides for the grade adjacent to the structure to be 1.2' (minimum) above the highest floodplain elevation. The grades away from the house is approximately 17% to 22% with the flows running into the side yard swales. The runoff from the front of the structure will flow to the side yard swales and then flow to the rear as has historically occurred. This proposed structure should not change the historic drainage of the surrounding areas nor impact the adjacent properties. Stormwater runoff will flow around the proposed structure on either side and will reach the rear of the lot as historically has occurred in the side yard swales. The top of foundation, adjacent finish grades, spot grades, side yard swale flowline grades, and elevations shown on the Plot Plan/Grading Stratton Builders 132 N.

All gutter down spouts should discharge to either the front or rear of the structure. If you have any questions, please feel free to contact our office.

The existing subdivision (Morger Smith Subdivision) was established around the 1900's and there is an existing water service stub from the main located in North Shields Street. However, an interior meter for residential service line will need to be installed in the northwest corner of the basement of the proposed structure in accordance with the City of Fort Collins standard details, a copy of each is attached to this memo. The sanitary sewer service line shall be connected to the existing sanitary sewer main located in the alley to the north of the proposed structure. Based on information provided, the basement cannot be served with sewer by gravity and a grinder ejector pump will be required for all facilities in the basement. It is recommended that these be kept to a minimum. However, the main floor and upper stories can be served by gravity. It is suggested that laundry facilities be kept on the main floor. The service line shall be 4" diameter SDR 35 PVC installed at a minimum of 2% with a clean-out outside the structure and tie-in to the main using a tapping saddle with bands similar to the one in the attached detail. The sewer main will need to be "wet tapped" by the City of Fort Collins or a contractor authorized by the City to make the connections. The line is reported to be 6" VCP and requires special tapping requirements. If you have any questions, please feel free to contact our office.
