HomeMy WebLinkAboutPVH HARMONY CAMPUS (PHASE 1) - PDP - 32-98A - CORRESPONDENCE -comments from the previous page:
No curb return profiles were provided.
Please provide profiles of the north and south edges of the medians as well as
flowline/edge of asphalt profiles.
Please provide full cross sections of Timberline Road. Include cross slopes, flowline
elevations, ROW limits, medians, major utility crossings, etc.
�k The median in Timberline Road will need to be designed to allow for pedestrian refuge.
Hence, it needs to be pulled into the crosswalk.
Please include the appropriate side slopes as stated in the SHAC. This includes,
beginning at the edge of asphalt, a 6:1 slope for 12 feet, 4:1 slope for 6 feet, and no
steeper than 3:1 slope thereafter.
Please provide a preliminary design of Harmony Road 1000 feet beyond the
construction limits. You will need to show interim and ultimate improvements. The
design of Harmony will need to meet the requirements stated in the new State
Highway Access Code.
You will need to acquire offsite easements and possibly ROW for the improvements to
the Harmony Road/Timberline Road intersection.
Please show interim and ultimate improvements to Harmony Road. I would suggest
having two different sheets (1 for the interim/short range improvements and another
sheet for the long range/ultimate improvements).
Please provide profiles of the north and south edges of the medians as well as
flowline/edge of asphalt profiles.
Please provide full cross sections Harmony Road. Include cross slopes, flowline/EOA
elevations, ROW limits, medians, major utility crossings, etc.

15. Please provide cross -sections of both spillways in the plans that include all
dimensions and other information.
RESPONSE:
Erosion/Sediment Control Comments
1. All previous comments have been addressed, plan is OK. Thanks.
Please refer to the redlined plans and report for additional review comments
pvhhc-3.doc
9. Please clarify the boundary between sub -basins 3 and 32 (which appears to be
missing).
RESPONSE:
10. Some of the flows along Harmony Road still need to be considered, specifically from
sub -basin 2. Has the amount of flow to the irrigation ditch changed? Why not direct
the flows from Hannony Road to Pond 393 via inlets and storm sewers? Please
address these concerns. In addition, CDOT and the ditch company will need to
approve of any changes in this area. Please provide approval letters from them.
RESPONSE:
11. The spillway for Pond 393 is currently positioned to flow into a field. Please explain
the reasoning for this alignment or place the spillway to flow directly into the outflow
swale. In addition, please show the spillway and top of berm elevations on the
grading plans to designate the location.
RESPONSE:
12. Please provide detailed grading exhibits for Pond 394 and Swale B8 in the grading
plans. Be sure to include the pond spillway and top of berm elevations to designate
the spillway location.
RESPONSE:
13. The City of Fort Collins no longer maintains the benchmarks used at the site. Please
use one of the current City vertical control benchmarks to tie-in the site elevations.
RESPONSE:
14. The equalization pipe for Pond 393 is a concern. Has the potential for delay effects
from the equalization been examined? An EXTRAN analysis in conjunction with the
SWMM analysis would clarify this concern. Please indicate with calculations and
documentation that the size of the equalization pipe is sufficient. This is a repeat
comment.
RESPONSE:
pvhhc-3.doc
3. Please use the revised rating curve for pond 393 in all the SWMM analyses. In
addition, please revise the rainfall hyetograph used for the 10-year SWMM analysis
(see page 64 of the redline report). Please double check and make sure that the
SWMM rating curves for ponds 393 and 394 are complete and accurately reflect the
values calculated.
RESPONSE:
4. There are several discrepancies noted in the UDSEWER analysis of storm sewer
profiles A & B. Please revise these values and clarify as needed. One important
issue is in regards to profile B — The design flow at manhole #3 (60.3 cfs) only
accounts for sub -basins 1, 15, & 18. It does not seem to account for basins 12 & 14
(14.8 cfs) which also contribute flows at manhole #3.
RESPONSE:
5. The ground surface elevations for storm sewer profile A & I on the plans do not seem
to match those used in the UDSEWER analysis. Please clarify.
RESPONSE:
6. Please include some of the F1owMaster results that were obtained for tailwater
elevation estimates in the rating curve calculations for both ponds.
RESPONSE:
7. The riprap calculations are confusing. Please show how (with an equation) the d50
value was obtained for each calculation. Also, please explain why the method used
does not finish with that method's sizing technique (i.e., Class 6 instead of Type L).
RESPONSE:
8. On the drainage plan, please provide cross -sections of the detention pond emergency
overflow spillways with dimensions/elevations indicated, and also indicate the
spillway elevation and top of berm elevations on the grading plan.

a. Fire apparatus access roads shall be provided for every facility,
building or portion of a building hereafter constructed or moved into
or within the jurisdiction when any portion of the facility or any
portion of an exterior wall of the first story of the building is located
more than 150 feet from fire apparatus access as measured by an
approved route around the exterior of the building or facility. This
fire lane shall be visible by painting and signage, and maintained
unobstructed. A fire lane plan shall be submitted for approval prior
to installation. Any building not meeting theis criteria shall be fire
sprinklered.
Note: Timberwood Drive shall be established and in place prior to
issuance of certificate of occupancy for any structure built.
b. Fire hydrants are required with a maximum spacing of 600 feet
along an approved roadway. Each hydrant must be capable of
delivering 1000 gallons of water per minute at a residual pressure
of 20 psi. Hydrants shall be of an approved type'as defined by the
water department and fire department. No commercial building can
be greater than 300 feet from a fire hydrant.
C. Address numerals shall be visible from the street fronting the
property and posted with a minimum of 6 inch numerals on a
contrasting background (Bronze numerals on brown brick is not
acceptable).
The MOB shall be addressed separately from the A.CC
d. Proposed buildings shall be fire sprinkled.
The use of the MOB is totally different from the use of the ACC.
Therefore, an area separation wall will be required between these
two uses so that the different populations using these buildings will
be influenced as separate populations upon the buildings going
into alarm condition.
This completes the review comments at this time. Additional comments may be
forthcoming as the various departments and reviewing agencies continue to
h. Typically, a sanitary sewer service is no larger than 6-inch. Is a 10
inch sanitary sewer service needed?
i. A 4-foot minimum cover is required over all sanitary sewer mains
and services.
j. Provide a separate detail for each water main lowering showing the
following information:
Elevations of water main at beginning, lowered and ending
positions.
Elevation of item being crossed (i.e. storm sewer, sanitary
sewer, etc.).
• Define which is a gravity block and which is a thrust block.
k. Show vaults for each Air Relief Valve in profile view. Reconfigure
12-inch water main profiles in order to eliminate all unnecessary Air
Relief Valves and bends when possible.
I. Place one valve between each fire hydrant.
M. Show water mains and services in storm sewer profiles. Provide a
minimum of 18 inches of vertical separation between water mains
and all other utilities in profile views. Indicate concrete joint
encasement on larger storm sewer crossings.
n. Provide joint encasement detail on detail sheet.
o. See site, landscape and utility plans for other comments.
p. In response to the request to increase the berm height along
Harmony Road — It is our understanding that the
Planner/Landscape Architect has requested that the height of the
berm above the water main be increased to 3 feet in a few areas.
We can allow this increase provided it is limited to "a few areas."
Please provide information defining the extent of these areas.
Streets
a. Concerns remain about the timing of the construction of
Timberwood Drive and Snow Mesa Street. These need to be
constructed with this phase to provide connections to the Wildwood
development to the east and the Timber Creek PUD to the south.
that all rooftop mechanical equipment be screened from public
view by integrating it into the building and roof design to the
maximum extent feasible. The proposed screening clearly
appears as an add -on. The screening should be integrated into
the overall design theme and architecture of the building.
Please refer to Section 3.5.1(J)(2) of the Land Use Code where
it states that "...no attention is (to be) attracted to the functions
by use of screening materials that are different from or inferior
to the principal materials of the building and landscape."

Harmony now in order to finalize design. _
e. Move meter pit for proposed building out of sidewalk.
f. Label all fittings, plugs, thrust blocks etc. on services and fire lines.
g. Provide sizes for all sanitary sewer services and include their
inverts when installed into manholes in profile view.
further than 20 feet away from any public street, sidewalk or
pedestrian way and requires that the "visual and acoustic
impacts .....are fully contained and out of view ...."
e. The image analysis submitted as part of the building height
review is of inadequate quality. It is difficult to discern the
foothills in the background in order to identify the extent of the
blockage of any views from Harmony Road. Please submit a
better quality rendition.
f. In scaling the width of the sidewalk adjacent to the private road,
it appears to be 4 to 5 feet. Sidewalks are to be 6 feet in width.
g. Directional handicap ramps need to be used for the sidewalks
at all intersections.
h. Stop signs should be provided on both the northern and
southern legs of the intersection of Timberwood Drive (and the
private'road on the north) and the entry from Timberline Road.
i. Please provide a further description of what an "enhanced"
crosswalk will be. A detail of these walkways must be provided.
The right-of-way for the unused entry off of Timberline Road will
need to be vacated. Please coordinate this with Tim Blandford
of the Engineering Department.
k. The site plan needs to indicate an enhanced pedestrian
crossing of the Timberwood entry from Timberline Road as well
as the extension of the sidewalk to join the existing sidewalk at
Timber Creek PUD.
I. Please show a sidewalk on the eastern side of Snow Mesa
Street on both the site and landscape plans.
M. Street trees must be provided on both sides of the Snow Mesa
Street entrance from Harmony Road. Please show these on
the landscape plan.
n. Please consider extending the berm adjacent to the service
area to the north with additional trees. This would enhance the
buffering of the mechanical equipment located there.
o. Thank you for a much better submittal of architectural
elevations. One remaining comment concerns the screening of
the rooftop mechanical equipment. Section 3.5.1(J)(5) requires

RE. Comments on the Poudre Valley Health System Harmony Campus
Project Development Plan
Dear Angie:
City staff has reviewed the revisions to the Poudre Valley Health System
Harmony Campus Project Development Plan and offer the following comments:
Current Planning
a. Metal halide lighting is acceptable for highlighting the hospital
logo. However, the light needs to be highly directional to
prevent any spillage outside of the logo boundaries.
b. The photometric plan is unreadable at the upper portion near
Harmony Road. Please resubmit a readable copy. This plan
must show the effects of the on -site lighting off -site for a
minimum distance of 20 feet. Section 3.2.4(D)(8) of the Land
Use Code requires that light levels measured 20 feet from the
property line be limited to one -tenth (0.1) foot candle as a result
of the on -site lighting.
C. The Electric Site Plan indicates flag poles are planned near the
water feature at the entrance to the MOB. These are not shown
on any other plan sheets. Please ensure the various plan
sheets are consistent.
d. Your response letter indicated that a trash compactor is to be
located in the service area. This is not shown on any of the
plan sheets. Your letter also indicated that the compactor will
not be enclosed. Please refer to Section 3.5.1(J)(1) & (2) of the
Land Use Code which limits the location of this compactor to
