embankment.
54. The sidewalk and parkway widths are easily discernible from the cross-section drawings.
55. The cross -sections have been modified to show a minimum I'spacing between the sidewalks and
the beginning of slopes.
56. Sidewalk adjacent to the curb has been labeled as being 7' wide.
57. Off site easements are being provided via separate documents. These easements were prepared
by King Surveyors for the Developer.
58. The drive over curb details have been corrected and now show a 12" thick section at the back of
curb.
59. The 1 foot inflow curb and gutter detail has been removed from the plans.
60. The outflow curb and gutter is being used in the median at the intersection of Trilby Road and C.R.
36. The street plan and profile drawings have been modified to show the location of the outflow curb
and gutter.
61. Detached and attached curb and gutter comer access ramp details have been provided.
62. The plans now call for the use of type III barricades per the City of Fort Collins.
63. Detail D-15 has been added to the plans.

33. The grade breaks at the entries to the pan are far less abrupt than that created by the pan itself, and
traffic will be slowing as it approaches. This configuration should not present any more adverse
driving conditions than a typical intersection cross -pan.
34-35.The layout is identical with the approved Preliminary Plat for the Fossil Lake PUD. This layout has
been consistently used from preliminary through final submittals. We feel the configuration will
function adequately. The developer and Northern Engineering reviewed altemativesto the proposed
design and determined that changes were not feasible without significantly altering the plan.
36. The intersection of Trilby and Stone Water Drive has been modified to maintain cross -pan slopes
of a minimum 0.60%.
37. The profiles of Trilby Road immediately south of Muskrat Creek Road have been modified and are
now in compliance with the minimum K value requirement of 60.
38. The Trilby Road and Rock Creek Drive intersection has been modified so that the slope of the cross -
pan is in compliance with the 0.60% minimum. Due to close proximity as well as drainage
requirements the vertical curves in Trilby Road between Rock Creek Drive and C.R. 36 fall short of
the standard K values for a collector and fall more in line with those of a local street. However, due
to the nearness of the Trilby Road and C.R. 36 intersection the traffic will either be accelerating from
or decelerating to a stop in this block of approximately 233 feet. Consequently, the traffic speeds
will most likely never achieve the design speed of a collector.
39. The Trilby Road transition has been adjusted and no longer occurs in the intersection. The nose of
the median at the entrance of Trilby Road has been adjusted to avoid interference with the
crosswalk.
40. The pedestrian ramp location has been adjusted to avoid interference with the sidewalk culvert.
41-43. The approaches to intersections were adjusted to provide a maximum 2% approach.
44. Filing One design information has been provided to illustrate how Shallow Pond Drive ties into Trilby
Road.
County Road #36
45. The ultimate and interim designs have been delineated on the plan and profile drawings. Ultimate
design has been provided 1000' beyond the boundaries of the site.
46. Culverts within the row have been called out as RCP.
47. Sidewalk adjacent to the curb has been called out as being 7 feet wide.
48. Spot elevations have been provided at the intersection with Trilby Road.
49. The inlet on the north side of the box culvert will be built at the same time as the culvert.
50. Temporary construction easements for grading driveways outside of the row will be provided by
separate document. These easements will be obtained by the Developer prior to the
commencement of construction.
51. The typical pavement section has been modified to indicate that it is per the final soils report.
52. The striping plan has been modified to provide 50:1 transitions.
12. Note 17 has been removed from the plans.
13. The specified notes were added to the plans.
Phasing Plan:
14. A temporary turnaround has been provided at the end of Stone Water Drive with Phase 1.
15. A note has been added which states that C.R. 36 improvements are to be constricted as part of the
Phase 3 constriction work.
Overall.
16. The required sight distance easements have been provided.
17. Easements for all offsite work are being provided via separate documents. These easements were
prepared by King Surveyors for the Everitt Companies.
18. Sidewalk ramps have been provided were indicated. Any change in sidewalk width which occurs
outside of the right-of-way is in accordance with agreements between the Developer and Larimer
County.
19. The eyebrow at the intersection of Falling Water Drive and Rock Creek Drive has been designed
in accordance with Larimer County Engineering Department guidelines.
20. Rock Creek Drive has been renamed as Long Creek Drive.
21. The midblock cross -pan has been increased to a 20' width.
22. Fossil Lake PUD, First Filing plan and profile information has been provided where Second Filing
streets tie into the First Filing.
23. The vertical curves have been modified to comply with City of Fort Collins requirements. Any
instance of non-compliance will be addressed individually.
24. Additional information has been added to better illustrate the pan and per grades at intersections.
25. No change.
26. Crown transition distances have been called out at intersections.
27. Curb openings and inlets have been called out on the street plan and profile drawings.
28. Cross -pans have been adjusted to reflect a minimum slope of 0.60%.
29. Riprap has been called out at the ends of "dead end" streets.
30. Driveway locations have not been shown on the plans.
31. Offsite design of 500' has been provided for all streets where appropriate.
32. No comment provided.
