RE: #55-84N Ridgewood Hills 4`h Filing
Tract N & T PDP
Dear Mr. Olt,
RECEIVED
SEP ? " 2R05
CURRENT PANNING
The Fort Collins - Loveland Water District and the South Fort Collins Sanitation District have reviewed
the above mentioned request and submit the following comments.
Access to the existing sanitary sewer line is required.
The District requires easements, on the District's standard easement form, for all facilities that
are not located within the public ROW. The minimum width of the easements is 20 feet,
depending on the depth of the facilities. There does not appear to be adequate horizontal
clearance from the face of the curb to the sanitary sewer line in many locations
The water and sanitary notes on sheet 2, general construction notes, need to be corrected to
reflect District requirements. Notes #2, #3, #6 and 13 under the water main notes are to be
deleted. Notes #2, #3,and #7 under the sewer main notes are to be deleted.
The District does not allow trees within 10 feet of District facilities.
A fire hydrant is to be installed on the dead-end stub at the east end of Avondale Road/
The water main on lot 29 is not to be located under the driveway.
The water line near lot #7 is too close to the type `R' inlet.
The water and sanitary sewer service size needs to be indicated.
Irrigation taps need to be identified if applicable.
The meter pits are to be grouped for each structure in one location for that structure.
The District's current water and sanitary sewer typicals are to be shown, the City of Fort Collins'
water and sanitary sewer typicals and details are to be deleted.
The sanitary sewer profiles were not submitted for review.

2. Retaining walls should not be on top of storm sewers, as shown in
some areas on this development plan.
3. Because of the above expressed concerns this development proposal
is not yet ready to be scheduled for a public hearing.

Topic: Water Quality
Number: 130 Created: 9/26/2005
19/26/05] The site still needs to provide water quality detention, how will
this be accomplishes if all the flows are sent to the downstream system
undetained. The larger pond may need to be retrofitted, or you will need to
provide your own water quality detention on -site.
Department: Transportation Planning Issue Contact: David Averill
Topic: Site plan
Number: 70 Created: 3/22/2005
[9/21/05] We need to take another look at the alignment of crosswalk
ramps and striping at this intersection.
13/22/051 Please align the crosswalk ramps on the north sides of Avondale
at Woodrow so that the crossing is perpendicular to the roadway. The
eastern ramp of this crossing is slightly askew to the south. Thanks.
The following comments/concerns were expressed at the City staff review
meeting on September 121, 2005:
Engineering (Dan DeLaughter, 221-6605):
1. The proposed 4 new dwelling units shown on these revised
development plans are in a drainage easement and detention pond.
How is the loss of the storm water detention going to be addressed?
2. There is a storm drain inlet & handicapped ramp conflict at Woodrow
Drive and Avondale Road.
3. The development plans show a grading easement at the end of
Avondale Road. Is this easement existing?
4. Are the necessary sight distance variances approved?
5. Another utility coordination meeting may be necessary.
6. Because of the above expressed concerns this development proposal is
not yet ready to be scheduled for a public hearing.
Stormwater (Basil Hamdan, 224-6035):
1. With the addition of the 4 dwelling units the Stormwater Utility has
to determine what effects are associated with the loss of the
detention pond.
Page 7
4. On the plan sheet, your note #5 - where is this?
5. What keeps the sediments from running down the south swale and the
east silt fencing into the completed detention pond to the southeast of
the project?
6. Etc.
Topic: Grading
Number: 129 Created: 9/26/2005
[9/26/051 Need to use surveyed elevations for grades, plan states that
grading was taken from approved Ridgewood Hills 3rd Filing plans. Please
verify these elevations with survey shots at final.
The plan calls for a swale along the south property line. The cross-section
calls for a 16 foot wide swale, however, at the most restricted area there
appears to be only about 5 feet between the property line and the retaining
wall.
Topic: Plat
Number: 127 Created: 9/23/2005
[9/23/051 Plat states that the portions of the drainage easement located on
Tract C are to be left intact, however this revision adds lots 42, 43, 44 and
45 where tract C was located, consequently the portion of the easement
where these lots are to be located need to be vacated by the plat.
Topic: Storm Drainage Lines
Number: 128 Created: 9/23/2005
[9/23/05] Most of the plans still show old storm drainage lines that were
proposed with the previous site design. Please correct the plans to reflect
the latest storm drainage lines and design as proposed.
Show the existing outfall pipe and identify it on the plans.
Why doesn't the pipe coming off of Avondale Road extend to the outlet pipe.
As designed, severe erosion will occur downstream of that pipe, this will not
be allowed. Please modify.
Topic: Utility Plans
Number: 131 Created: 9/26/2005
[9/26/051 Please call out all proposed and existing storm sewer lines and
appurtenances on the overall utility plan sheet.
Please provide a legend.

Topic: Detention and hydraulic calculations
Number: 132 Created: 9/26/2005
[9/26/05] This proposal requests that a variance be allowed for less than a
1-foot of freeboard in Pond. This is acceptable as long as water quality
requirements are also met in that pond. Need to ensure that total volume
required for quantity and quality remain below spillway elevation.
Please clarify the SWMM model schematic, indicate what geographic area
would be covered by the reconfigured SWMM basins.
The hydraulic analysis of the pipe system between the site and pond 2 was
done using a full flow situation, however, tailwater conditions would arise
when the pond is full and the pond should be analyzed as such.
Please study the overflow situation, what happened when the downstream
pipe is full or plugged ? Make sure none of the downstream homes would be
affected negatively.
Topic: Drainage
Number: 102 Created: 9/20/2005
19/20/051 Now that the pond has been eliminated, need to make sure
downstream pipe has sufficient capacity.
At final need retaining wall design.
Extend pipe coming into low area and tie to outfall pipe.
Topic: Erosion and Sediment Control

1. One or more of the previous comments has not been addressed. Please
do so.
2. The report states that some BMP's may happen, others should happen,
etc. This is the document that defines what shall happen, and when
and in what order. Please change the report to reflect this.
3. On the plan sheet, your note #4 should read, "all disturbed areas are to
be seeded and mulched".

19/21 /05] A greater portion than shown in your section for Triangle Dr. will
have to be sawcut. The street cut will have to be wide enough to include the
utility connections. Please include the street cut note as indicated on the
redlines and update your sections.

[9/21/051 Please see redlines for additional comments.
Number: 121 Created: 9/21 /2005
[9/21/051 Utilities have concerns about connecting to the 4 new units
being proposed. Please contact me to schedule a utility coordination
meeting. (970-221-6605).
Number: 122 Created: 9/21 /2005
[9/21/051 Scanability remains an issue for many of the plans, please
consult LCUASS Appendix E for guidelines.
Number: 123 Created: 9/21 /2005
[9/21 /05] Flowline proffies will be needed for all streets for final compliance.
Topic: Plat
Number: 106 Created: 9/21 /2005
19/21 /05] Remove the vacation statement on the plat. The easement
vacation note is sufficient once the city signs off on the plans.
Department: Light & Power Issue Contact: Rob Irish
Topic: Light & Power
Number: 98 Created: 9/20/2005
[9/20/051 Paired water services between lots 16 & 17 on Tract N have not
been separated. All paired services along Woodrow Drive have been. Thank
you.
Number: 99 Created: 9/20/2005
[9/20/051 Contact Rob Irish at Light & Power to coordinate exact location
of ganged meters for Tract N and Tract T. Also, need to coordinate electric
facilities to lots 42/43 & 44/45. These were not existing when we had the
utility coordination meeting.
Number: 100 Created: 9/20/2005
[9/20/051 Just a reminder that the existing electric vault along Triangle
Drive will need to be relocated and all new cable pulled in. This will be at
the developer's expense.

Number: 124 Created: 9/21 /2005
19/21 /05] Technical Services has concerns about shared public and
private easements. We will want the two to be dedicated separately and
elaboration is needed regarding "private access." Who are you intending to
limit these for?
Topic: General
Number: 104 Created: 9/21 /2005
19/21/05] Update all plans to show directional access ramps. Site and
landscape are still showing the old ones.
Number: 110 Created: 9/21 /2005
[9/21/051 The access ramp on the S. side of Avondale overlaps a storm
water inlet. It is allowable to remove both this ramp and the ramp opposite
since only 3 ramps are required at a T-intersection. If keeping the ramp,
relocate the storm inlet.

[10/3/051 Dennis Greenwalt of Comcast Cable TV has indicated that they
would like to see a utility easement along the south lot lines of Lots 11. 12,
13, and 14. Without this easement it may be an issue to service Lots 13 &

Topic: General
Number: 133 Created: 9/29/2005
[9/29/051, The revised plans now include an additional 4 dwelling units
(42 - 45) on Tract T of the development plan. City staff, not having
anticipated this when the last comment letter went out to the applicant, did
not request enough copies of the subdivision plat, Site Plan, Landscape
Plan, and utility plans for the appropriate City departments and outside
reviewing agencies to receive, review, and comment on. Therefore, another
round of review will be necessary with a re -submittal of the number of
copies of each document as shown on the "current" Revisions Routing
Sheet.
