West Sewer Truck Line Design Report, as such the property was assumed a sewer demand.
The applicant must verify the assumed flow and provide an estimate for the peak-hour
sewer demand for the proposed project. The project main not exceed the sewer flow that
was assumed in this report for the property. Please provide a design report outlining the
demands the proposed development and the assumed flow from the Valley west design
report.
Response: Included in this resubmittal are the calculations for the anticipated
wastewater discharge from the development.
As shown in the provided wastewater calculations, the daily demand allocated in the
Valley West Sewer Trunk Main for Block 5 is 24,694 gpd (peak hour1,029gph). The
calculated wastewater discharge from the Town and Country Foods store and future pad
site is 6,136 gpd (peak hour – 959 gph). Based on these calculations the proposed
development discharge is below the trunk sewer allocated capacity.
Stormwater
4. BMC 38.410.080: Modifications to the subdivision drainage system have taken place
incrementally with subsequent site development. The City has require that modification

reconstructed with Phase 1. The east basin will remain as-constructed. Modification to
the stormwater report for the future phases will be required with the future site plan
review(s).
5. The season high groundwater elevation (SHGWE) must be identified within the
stormwater design report and all storm water facilities be located above this elevation.
Response: Groundwater monitoring was completed in 2020 during seasonally high
ground water and the maximum water level was 4816.6. The bottom of the proposed
revised basin is 4817.25. Monitoring will continue in 2021. The first reading in May
2021 showed the groundwater level at 4816.05
