I have reviewed the application for the Sierra Homes Short Plat project located at 702 Nile Ave NE and have the
following comments:
The following comments represent additional information or corrections that are required to be made:
1. In the TIR a flow control facility exemption is claimed for core requirement #3. However, the modeling
used to support the claim must be revised for the following items:
a. The WWHM model used an hourly timestep, a 15 minute timestep shall be used.
b. The WWHM model has a target surface area of 0.195 AC which is equal to the new impervious
surface only. However, per section 1.2.3.1.B – Target Surfaces – 2 the new pervious surface shall
be assumed to be the entire lot area. The total lot area is 0.735 AC and thus both the predeveloped
and developed conditions should have an area equal to 0.735 AC.
c. The WWHM model appears to use flow control facility sizing credits, however, per table 1.2.9.A
privately maintained BMP’s are not allowed to receive facility sizing credits unless using f ull
dispersion or full infiltration (neither of which are indicated as feasible).
d. If a flow control facility is found to be required, then the applicant shall demonstrate that there is
no downstream drainage problem to the wetland; See section 1.2.2.1.1 – Potential Impacts to
Wetlands Hydrology Problem of the RSWDM for further information.
2. The TIR appears to be based on the 2022 Renton Surface Water Design Manual (RSWDM) however there
are references to the 2017 RSWDM. The report shall be updated for compliance with the 2022 RSWDM.
The following comments represent additional information or corrections that should be made when considering
site layout:
1. All existing and proposed utility lines along the property frontage must be relocated underground per
RMC 4-6-090. There is an existing utility pole along the properties Nile Ave NE frontage that shall be
removed and those services spanning to the north and south shall be installed underground to the next
utility pole. Those utilities that service houses on the west side of Nile Ave NE from this span may remain
overhead, however, only up to the serviced properties connection with the ROW; a new service pole may
be installed to retain overhead service and that portion of the service within the ROW shall be installed
underground. Further the subject utility pole contains an existing streetlight, a new streetlight conforming
to COR std. plan 117.1 shall be provided.
