ISSUES:
Department: Engineering Issue Contact: Katie Moore
Topic: Utility Sheet C2
58
Please provide 2 Fort Collins Benchmarks, and correct note 38 to reference this project.
3.5.02: Note 24 references the City of Loveland. It should reference the City of Fort Collins Vertical Control
1998, 1 believe.
Please add note #40 listing approved variances.
Topic: Utility Sheet C5
61
The retaining wall around the planter will not be allowed within the ROW.
Topic: Utility Sheet C5-Grading
82
How will the grading work after phase 1 and before phase 2? Each phase must stand alone, and I'm not sure
how this will work.
Topic: Utility Sheet C7
62
Please show spot elevations on the plan view of Linden. Spot elevations should be provided at the stations
and at the beginnings and endings of vertical curves and PCR's.
3.5.02: Please provide the spot elevations at the beginnings and endings -of vertical -curves -and -at -the
centerline on the northern limit of construction on the plan view. The other spots were addressed.
65
Single point grade breaks are limited to 0.4% per 7.4.1 LCUASS. Only one of the grade breaks shown meets
this requirement.
3.5.02: Several grade breaks have been corrected, but there are still excessive breaks at both ends of the
proposed improvements. The 4% grade break at the north end is especially large.
66
Please smooth out the grades around the curb returns to the private drive.
Topic: Utility Sheet C7-Linden plan and profile
83
Page 1
The sight distance shown can be measured along the east flowline of Linden.
What is existing in the area shown to be needed to the west of the ROW? Are there any sight distance
impediments?
84
Please show centerline elevations along with each flowline elevation on the profile.
85
Type III barricates shown at the north end of the improvements to Linden do not appear to be standard.
Please see revisions to the detail and provide straight barricades that block the sidewalk and parking lane
but do not protrude beyond the existing edge of asphalt.
Topic: Utility Sheet C8-Linden Cross -sections
86
Please remove notes referring to pavement designs. Such designs will be reviewed by Pavement Engineering
at a later date.
87
Please show the true cross -slopes from the curb to the edge of ROW to the east.
Department: Police
Topic: Site Plan
Issue Contact: Joseph Gerdom
39
Landscape: The location of the Montmorency Cherry and Autumn Blaze Pear (east of the building) isolates
the eastern most parking area. Recommend lower growing shrubs at both locations.
Lighting and Building Access: Two doors opening to the west and one opening to north (at north end of
building) have no apparent security lighting. Further, the north access point is obscured by the Blue Spruce
plantings. Recommend some form of security lighting at these doors and moving the Spruce away from the
north access point.
Department: Stormwater Utility
Topic: Drainage
Issue Contact: Wes Lamarque
96
The proposed C-factor for sub -basin 5A-3 is only .27, yet this area is planned for a future parking lot. The C-
factor was higher the previous submittal and was reduced. Please use the corresponding C-factor for the
ultimate site plan design and -revise -all -hydraulic -calculations. associated -With this new flow.
97
The on -site flow for the 2-foot pan on the east -side of the site and for the private drive storm conveyance
does not seem to correspond to any flows in the hydrology calculations. Please revise calculations.
98
The WQ ponds revised calculations say that 10% of the site drains to WQ Pond B, when the schematic shows
that 90% of the site drains to WQ Pond B. Please clarify and revise calculations if needed.
100
Please provide a cross-section for the private drive just before Inlet 1 with the HWL for site flows and all off -site
flows to show drive has capacity as an ouffall due to smaller storm sewer being constructed.
Topic: Erosion/Sdiment Control
99

1. One would assume that site access was at the point of the vehicle tracking pad in the southeast corner of
the site, which means the silt fencing shown on the plan at that location cannot extend across the opening.
Otherwise, the plan is OK. Thank you.
