Please provide 2 Fort Collins Benchmarks, and correct note 38 to reference this project
Topic: Utility Sheet C4
59
Radii of driveway entering Linden should be 15' per table 8-2 in LCUASS.
Topic: Utility Sheet C5
60
Please complete the grading information for the landscaped area south of the drive and show drainage
basin lines for the area.
61
The retaining wall around the planter will not be allowed within the ROW.
Topic: Utility Sheet C6

Linden should be reconstructed to the south property line (sta 10+00). Please remove any notes referring to
sawcuts.
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.
63
Spot elevations for the driveway intersection should be shown in accordance with Figure 7-32 A of LCUASS.
64
The sight distance easement is shown for the incorrect design speed. The design speed for a collector street
is 40 mph, and the sight distance should be 660' per table 7-3 LCUASS.
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.
Please smooth out the grades around the curb returns to the private drive.
67
Since the design speed for Linden is 40 mph, the minimum vertical curve length required is 120' (fig 7-18
LCUASS).
68
The driveway should be shown as concrete to the ROW.
71
Please provide flowlines for both sides of Linden.
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.
Page 2
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 Issue Contact: Wes Lamarque
Topic: Drainage
53
Basin 5A-3 is entirely impervious (or close enough) yet the c-coefficent is only 0.27. Please revise and make
the corresponding changes throughout the plans and report. A more detailed review will follow after
hydrology is revised. There is existing asphalt in parts of Basin 5A-3 which will reduce this site's net increase of
flow if accounted for.
54
Once the hydrology is updated, I will review the analysis for the detention and water quality ponds. The
increase of flows may require modifications to the existing detention and water quality ponds. Please
provide an analysis using the new flows form this site, as well as all existing flows from other contributory
basins. Compare designed flows from previous reports with the site's new flows, which include the new
rainfall data. Please explain and provide documentation from previous reports regarding the ponds original
volume and what impacts this site will have.
55
Please provide documentation (drawings, calc., etc.) from previous reports that are referenced in the text
and calculations of this report in the appendix.
Topic: ErosionlSdiment Control
51
1. The site slopes from north to south -- why is there no silt fencing on the south perimeter?
2. If the existing area inlet (SE corner of the site) is currently surrounded by asphalt or concrete, straw bales
will not protect it. It must be in soil for the bales to work. I cannot tell from this plan --please make sure to use
the proper BMP's.
3. The note on the plan should read, "...all disturbed areas to be seeded and mulched."
52
Please provide a PE stamp on the report with next submittals.
