pump that can operate under different hydraulic conditions that the station
experiences, specifically column separation after pumping cycles. Montana
Department of Environmental Quality (DEQ) Circular 2 requires that multiple pumps
must be provided and of the same size. Units must have capacity such that, with any
unit out of service, the remaining units will have capacity to handle the design peak
hour flow. The station does not satisfy DEQ firm capacity requirements. The lift
station mustbe upgraded prior to final plat approval for any phase within Phase 5.
The Norton Ranch Lift Station is being upgraded to meet Montana Department of
Environmental Quality (DEQ) requirements and to adequately convey flow. As part
of the lift station upgrades scheduled to be completed, the existing submersible
pumps will be replaced with three (3) Flygt NP 3102 SH 3 Adaptive 256 pumps.
Each pump will operate with a variable frequency drive (VFD) that will improve
pump performance, primarily during pump startup when the pumps are pumping
against an empty force main. Two (2) pumps will serve as the main duty pumps and
will have a combined capacity to meet the peak design flow for Phases 1-6, to include
the proposed West Side Flats Subdivision, and the third pump will provide for
required redundancy. The approved lift station upgrades were designed by HDR,
Inc. and are scheduled to be installed during the summer of 2022.
22. BMC 38.410.070.A. 12 foot all weather access must be provided to each manhole
proposed outside of the public right-of-way, specifically sanitary sewer along the
northern property boundary. The existing asphalt pathway is not intended to support
the loading from a City vacuum truck. The applicant must provide a pavement design
report for the pathway demonstrating the necessary section required to support a City
vacuum truck and upgrade the pathway as need. This report must be provided with
the infrastructure submittal for the subdivision.
Understood. The existing asphalt path along Vaughn Drive is being removed and
replaced with the Phase 5A improvements so that it can support a city vacuum truck.

23. BMC 38.410.080.A. The proposed stormwater discharge from the detention pond on
the northwest corner of the development is located off-site. The applicant must obtain
an easement from the adjacent property owner for theoff-site discharge prior to final
plat approval of any phase within Phase 5.
This is understood. This has been provided to the city, and an additional copy is
included with this submittal.
24. BMC 38.410.080.A. The subdivision is responsible for maintaining the stormwater
system. A stormwater maintenance plan must be reviewed and approved with the
infrastructure submittal. The approved plan must then be incorporated into the POA
documents and a copy of the POA documents demonstrating inclusion of the
stormwater maintenance must be provided to the Community Development Division
prior to final plat approval of any phase within Phase 5.
Understood. The maintenance plan was approved with the Phase 5A and 5B
infrastructure and is included in the POA documents.
25. BMC 38.410.080.A. 12 foot all weather access must be provided to each stormwater
manhole proposed outside of the public ROW and extend into all proposed ponds.
This is understood. The 12-all weather access was provided and noted in the Phase
5A and 5B infrastructure plans.
26. BMC 38.410.130. The applicant must contact the City Engineering Department
(Brian Heaston) for an analysis of cash in lieu of water rights andpay any cash in
lieu of water rights due prior to final plat approval.
Understood. An analysis of the CILWR estimate for Phase 5B is included with this
submittal. The applicant has reached out to Brian Heaston and Griffin Nielsen
regarding confirmation of this estimate.
27. BMC 38.400.040.A.2. Street names must be reviewed and approved by theCounty’s
geographic information systems and City Engineering Departmentprior to final plat
approval. The applicant must submit written approval from both entities with the
final plat application.
This is understood. As previously noted the County GIS and City’s engineering
Department approvals are included with the final plat submittal. The final plat
street names have been updated per this correspondence.
28. BMC 38.400.070. Subdivision lighting special improvement lighting district
(SILD) information must be submitted to the City in hard copy and digital form.
Any final plat application for Phase 5 will not be deemed complete until the
resolution to create the SILD has been approved by the City Commission. The initial
adoption of the special improvement lighting district shall include the entire area of
the preliminary plat.
Understood. The special improvement lighting district approval is included with the
Civil/Structural Engineering and Surveying
final plat application.
29. BMC 38.220.060.A.1. A jurisdictional determination for the wetlands located
within Phase 5 must be obtained from the US Army Corp of Engineers prior to
infrastructure approval and final plat approval for phases 5B, 5C, or 5D of the
subdivision. The determination must be provided to the City prior to infrastructure
design approval.
This is understood. The jurisdictional determination is included with the final plat
application.
If you require any further information, please give me a call.
Sincerely,
Drew Kirsch, E.I.
