General Information
Location: The Harvey Mitchell Parkway Commercial Addition is located at the
South -east corner of Harvey Mitchell Parkway and Luther Street.
General Note: This commercial lot will flow into the proposed 8" sewer line. Thi line
will connect to an existing sanitary sewer manhole on the south as ide
of the property.
Land Use: Commercial
Design Criteria
Primary Sewer Outfall: An existing 8" sanitary sewer line along the south east side of the
property.
Domestic Demand:
Avg. Pop Density: 30 persons per acre
Average Flow: SO gpd /cap Commercial
Peaking Factor: 4
Pipe: PVC ASTM D 3034 SDR 26
Applicable Exhibits: Exhibit A — Sanitary Sewer System Layout
Exhibit B — Sanitary Sewer Analysis Spreadsheet
Conclusion
The proposed 8 " line flows into an existing 8 " sewer line on the
property. The analysis in Exhibit B checks the calculated slope required
to pass the estimated flow against the design slope shown on the plans.
The spreadsheet indicates the design slope is greater than the minimum
computed slope, so we conclude that the system is more than capable of
carrying the anticipated flow from these phases of the subdivision.
Exhibit B also shows the full flow velocity in the proposed line to be 3.04
fps and the calculated peak flow velocity to be 1. 42 fps.
