8. Please revise the time of concentration calculations for the developed conditions of this
property. Some of the concentration times seem high, and concentrated Sows should be
accounted for using flow velocities instead of overland flow,
RESPONSE:
For final submittal, please determine the upstream runoff contributing to the two 18"
culverts under Lemay Ave. and account for these flows in the drainage design These
flows must be passed through the site. The existing storm sewer may need to be

Notes:
1. This chart is intended as an irrigation design aid, related to the City's water conservation standard that
limits the size of. irrigated turfgrass area as a fiinction of the tap size. The above values are calculated cA,
assuming peak daily evapotranspiration rates of 0.25 inches for Kentucky Bluegrass and 0.20 inches for
Turf -type Tall Fescue. For the purpo7ies of the calculations, assume that the irrigation efficiency and tap
utilization efficiency are equal to 100%, and the maximum time of irrigation is 8 hours' More realistically,
however, this would be equivalent to irrigation and tap utilization efficiencies of 80%, and a maximum .
time of irrigation of 12 hours.
2. These maximum discharges assume a disk -type meter. In certain cases of irrigation. -only taps that are 1-
1/2" or larger, turbine meters are allowed, which have higher maximum discharge limits.

Hydraulic considerations
19. Where Kentucky Bluegrass and/or Perennial Ryegrass is used for turfgrass, the tap size shall be
sufficiently sized to deliver 0.25 inches of irrigation water over the turfgrass area within an 8
hour period. Where Turf -type Tall Fescue is used, the tap size shall be sufficiently sized to
deliver 0.20 inches of irrigation water over the turfgrass area within an 8-hour period. For
special circumstances, the Citymay allow exceptions to this standard. (See Attachment C)
20. The maximum system discharge shall be less than or equal to the maximum allowable, relative
to the meter size, as determined by the City of Fort Collins Water Utilities. This shall be as
follows: 3/4" - 10,gpm, 1" - 25 gpm, 1-1/2" - 50 gpm, 2" - 80 gpm, 3" - 160 gpm. These
maximum discharges assume a disk -type meter. In certain cases of irrigation -only taps that are
1-1/2" or larger, turbine meters are allowed, which have somewhat higher maximum discharge
limits. Contact the Water Utilities for more information.
21. The maximum velocities shall be less than or equal to 5.0 feet per second for mainline pipe- and $'
less than or equal to 7.5 feet per second for lateral pipe. (See Attachment C) '
22. The irrigation system shall be designed such that the point -of -connection design pressure;'';
minus the possible system pressure losses, is greater than or equal to the design sprinkler
operating pressure. (See Attachment D) .
23. _ The lateral pipe shall be sized such that there is less than or equal to a 10% variation' between
i the highest and lowest sprinkler operating pressures.on a zone.'.

10. For irrigation systems that are on a combined=use tap; with a water meter installed further
upstream to measure total water use, the installation of an irrigation -only submeter,should be
considered. This submeter would enable the owner and landscape maintenance contractor to
more easily determine water use for irrigation, and would not be used for billing purposes. The
cost of installation and maintenance of the submeter shall be borne by the owner of the.,,

1. If areas of planting are extensive, the installation of an underground irrigation system
required and an irrigation plan shall be submitted to and, approved by the City, prio
issuance of a final certificate of occupancy. If no building permit is required, the plan is due r 1 ` % ey�Ys
prior to commencing construction. If the'water requirements of the plants are low enough

the plants, the City may waive the requirement for an underground irrigation system. When -;
required, the irrigation plan shall be accurate and clear, drawn to the same�scale as the
SJ ,
associated landscape lan'and include the following:.'
!
a.' an annual Water Use Chart that includes: the square footage of irrigation zones, -
lateral precipitation rates (inches/hour), and seasonal Water use and cost. The seasonal ' a
water use data shall reflect the water requirements of the plants identified in the
landscape plan associated with the irrigation plan. The irrigation plan shall reference
the specific landscape plan, with its date and the designer's name. (See Attachment B)
b. a general note stating the point -of -connection design pressure and the peak flow. For
example, the system design assumes a minimum dynamic pressure for the irrigation { '
system of.75 psi at a maximum discharge of 50 gpm at the 1-1/2-inch tap and point-
. '4
of -connection. The irrigation contractor shall verifypressure and jlow on the site
prior to construction.
-.
P .
c. the design criteria to assist the installer with field adjustments, in a general note or in
the legend. The criteria shall include the sprinkler and nozzle specifications, the
sprinkler discharge at the design operating pressure, and the maximum distance
between sprinklers.
r:
d. a general note stating that, Any field adjustment or redesign of this irrigation system
must conform to the City of Fort Collins Irrigation Standards.
e. in the specifications, or as a general note, a requirement for the contractor installing., <
the system to provide the owner with as -built drawings after installation is complete,',
f. details of the installation method for bubblers or drip emitters, when the irrigation . Y
design includes these components. It must also include the number and discharge" rate
of emitters or bubblers per type of plant material. =

Irrigation methods and layout
.
2. Where untreated, raw Water is available 'from a nearby irrigation ditch or lake, it should be
considered as a possible -water source.
3. As much as practical, plants with dissimilar water requirements shall not be irrigated on the
'
same zone. For example, turfgrass areas should be on separate zones from planting beds. (See ,a
Attachment A for water requirements of specific plants).

_ 1. The landscape plan shall have a general note calling for the'review and approval by the City ; ti p
of Fort Collins of any required irrigation system, prior to the issuance of a Building
. 1+
2 The landscape plan shall include the total area (in square feet)'for each landscape category �R' ;<
Landscape categories are based upon water requirements. (See Attachment A, A Garde "to ` • < r'r;
Landscape Water -Requirement Categories)
3. Mulch shall be used for planting beds. The mulch can be either organic or inorganic, and { ,
shall be applied to a minimum depth of 3 inches. In order to prevent large expanses of
barren mulch, there shall be a minimum plant cover of 50% within five years of planting.:
Design Considerations
4. Group plants with similar water requirements on the same irrigation zone
5. Design the landscaping with an efficient irrigation layout in mind. For'example, the s
dimensions of.turfgrass areas should be in multiples of the radius of throw of the sprinklers,
and the geometry should be such that overspray is minimized.:
6. Minimize steep grades. Where necessary, design landscaping to minimize water runoff and
to take advantage of the water that does run off.. .
7. Use lower water -requiring plants on south -facing berms of 25% slope or greater.'
8. Minimize landscaping in strips less than 8' wide. When necessary, such as between sidewalk
and street, use lower water -requiring plants.
Natural Area Preservation
9. If there are portions of the site that are worthy of preservation, the alternative of leaving
them undisturbed or with only slight improvements should be considered: The worthiness of
_- such sites shall be determined by the City's Natural Resources Director.
Other good practices for water -efficient landscapes; but notfrequired '- "� `
• Have a testing laboratory' analyze the nutrient and fertilizer needs of the soil. For mostts' ils, `. 9
add at least 3 cubic yards of compost per 1,000 square feet. Rofotil to a depth of 6 to 8'::
inches.
Consider using lower water requiring turf and ornamental grasses.' Turf -type Tall Fescue is _ R
often a good substitute for Kentucky Bluegrass. For areas where a natural look is desired,
Buffalograss, Blue Grama Little Bluestein Sideoats Grama Smooth Brome Crested a`
Wheatgrass or Western Wheatgra§s'can be good choices: For more information about these..
grasses, call the CSU Department of Horticulture at 491-7019 `:

What are the water conservation standards.,,a
There are. two separate standards for water conservation.*(1) Landscapmg an
(2) Irrigation Systems. The standards for Landscaping promote the installation' of
/. ...,Z ,trn. J 7l �4ri lij
landscapes that require less water. The standards for Irrigation Systems ensure irrigation
systems are designed to apply water efficiently to meet the needs of the landscape
What projects are subject to the standards? Y
All projects within the city limits that are required to submit a landscape plan to the City ,.
as part of the development review process. In
general, this includes all commercial,'
industrial, institutional, and multi -family projects. Duplexes are also included when they ,
are part of a planned unit development. The standards apply to common areas of single- .
family developments, but do not apply to single-family residential lots
What do I have to do to comply with the Landscaping standards?
Submit a landscape plan as part of the development review process. The plan must meet
the requirements in'the document, Landscaping Standards for. Water Conservation before
the development plan is approved.
What do I have to do to comply with the Irrigation System standards?
Submit an irrigation plan as part of the construction permit review process. The plan must:.
meet the requirements spelled out in the document, Irrigation System Standards for
Water Conservation. The City will review the plan, and then inspect the system after
,installation. The irrigation plan and system inspection must be approved by the City
before a certificate of occupancy is issued. If construction of the irrigation system is
delayed until after construction is completed, a certificate of occupancy can be issued v;
only with an acceptable bond deposited with the City.
T
How strict are the standards?
The standards most important to water conservation are mandatory requirements, ` `a
identified with the word shall._ Other standards are more flexible, they use the phrases F
should or to the extent practical. These are enforced on a case -by -case basis.
Where do 1 get more information?

engineer licensed in the State of Colorado will be
required to demonstrate that the annual energy
consumption will be a certain percentage, less than the
same building just meeting the minimum standard in the
Model Energy Code.

r. The Elevations of the lube shop are not of the same quality as the
convenience store and need work. A standing seam metal roof similar to the
convenience store, awnings, fluted block, etc. should be discussed.
S. Based upon information submitted to date, this project achieves 11 % (6 out
of 54) of the maximum applicable points on the Auto -Related and Roadside
Commercial Point Chart (Point Chart D). A minimum of 50% is required by
Criteria 4. Without a variance to this requirement, failure to achieve 50% of
the maximum applicable points is grounds for denial. Please submit a
variance request to this requirement based upon the Variance Procedures
outlined in Section K (p.108) of the LDGS.
Specific issues related to Point Chart D are as follows:
Criteria 4b - This PUD is not part of an existing neighborhood or
community/regional shopping center. Therefore, no
points will be awarded for this criteria.
ii. Criteria 4e - This PUD is not mixed -use as it does not provide two or
more significant land uses. Residential use is proposed
on other areas of the ODP but not within the boundary
of this PUD. No points will be awarded for this criteria.
iii. Criteria 4f - Criteria #4f of Point Chart D asks if there is direct
vehicular and pedestrian access between on -site
parking areas and adjacent existing or future off -site
parking areas which contain more than ten parking
spaces. There is no direct pedestrian access between
the proposed uses on this PUD (see Transportation
Planner comments). Where is the adjacent existing
parking? Where is the future off -site parking? Without
further documentation showing direct pedestrian access
between the two buildings and/or agreements for
vehicular and pedestrian access with future parking
areas, no points will be awarded forothis criteria.
iv. Criteria 4g - No points were claimed for energy conservation on
Point Chart D, although a Method 2 calculation was
submitted. Method 2 is not valid as it has not been
updated to reflect the City's Model Energy Code as
adopted in July 1996. Therefore, in 'order to claim
points for energy conservation, the applicant must use
Method 1 which is an evaluation of the extent to which
the proposed building exceeds the minimum standard
as established in the Model Energy Code using the
b. Please provide a north arrow for the Vicinity Map on the Site Plan.
C. Please construct the gate on the trash enclosure of steel or metal rather than
wooden pickets.
d. Please modify General Note #6 on the Site Plan to state: "no outside
storage will be allowed."
e. Please specify that all lighting will be "down directional, with sharp cut-off..."
f. Please label the building footprint of the as a "gas and convenience store"
rather than a store model.
g. Staff is concerned about the size of the proposed canopy with the proposed
expansion shown.
h. Please show the actual site plan elements and dimensions rather than
designating with a number code and Legend. The legend really should only
have a symbol for handicap parking stalls, bike racks, etc.
Berms and more evergreen landscaping are needed along Lemay Avenue.
Please modify General Note #2 on the Landscape Plan to state: 'The
contractor is to furnish and install plant materials as noted on this Landscape
Plan. All plant material is to be AAN#1 grade."
k. Please modify General Note #16 on the Landscape Plan to state:
"Landscape and irrigation system installation to be completed prior to.....
.....the valuation of the landscaping and irrigation system (materials and
labor).
Please show the elevations of the columns for the canopy as wrapped with
brick for the entire height of the column.
M. Please note on the elevations that all building mounted, column mounted
security lighting must be down directional, sharp cut-off.
n. Please note on the elevations that all canopy lighting must be fully recessed.
o. Please note on the elevations that no window signage will be allowed.
p. What is the exterior mounted window sign below the Corner Store sign? Is
there enough signage allowance for this to occur? Please eliminate.
q. Please note on the elevations that the tops of the fuel pumps must be
opaque and non -illuminated.
b. Food service establishments require approval by the Larimer County Health
Department at the time of building permit application. Please contact Jim
Devore at (970) 498-6775 for submittal information.
C. Buildings shall be designed to comply with the Fort Collins Non-residential
Energy Code (ASHRAE 90.1 with local amendments).
d. Storage or use of hazardous materials must be in compliance with the fire
code and Chapter 9 of the 1991 Uniform Building Code as adopted by the
City of Fort Collins. A list of such materials with quantities and classifications
should be submitted for review at the time of building permit application.
10. The Natural Resources Department offers the following comments:
a. It seems that there are more than just three trees (old Cottonwoods) on this
site: What is going to happen to them? Can they be retained? Can
sidewalks be maneuvered around trees.
b. The location of the picnic table seems odd. Will this require parking spaces?
Is it too close to the trash enclosure?
C. Please design the trash enclosures to accommodate recycling bins and
collection.
11. Public Service Company requests that the plat dedicate 10 feet minimum width
utility easements adjoining the new easterly right-of-way line of Lemay Avenue and
the new northerly right-of-way line of Lincoln Avenue.
12. Comments from the Engineering Department are a#sehed Vor%ayroo
13. Comments from the Stormwater Utility are attached.
14. , The Current Planning Department offers the following comments:
a. As stated in the September 19, 1996 comment letter from Mitch Haas
regarding a previous Preliminary PUD application by Diamond Shamrock that
was withdrawn, this project must meet the requirements of the Interim
Design Standards and Guidelines for All Commercial Development, as well
as the All -Development Criteria of the LDGS. Specifically, it appears that
this proposal fails to satisfy items numbered I, , 3, and 9 of the Interim
Standards and Guidelines for All Commercial Development; and All -
Development Criteria A-2.2, A-2.4, and A-2.6 of the LDGS. Without approval
of variances (based upon Section K, p. 108 of the LDGS) to these criteria,
failure to satisfy any one of these criteria is grounds for denial. Staff feels
that a reverse layout could adequately address these criteria and suggests
that the applicant consider such a layout.
b. On the last page of the Hazardous Materials Impact Analysis please clarify
the following points:
Paragraph (1) references "absorbing material". Is this material
available on -site for use by the attendant or where does it come from?
ii. Paragraph (2) references that "it would be possible for the drive to
dam this curb opening...". What will the curb opening be dammed
with?
8. The Zoning Department offers the following comments:
a. Only two parking stalls are shown on the Site Plan (1 standard and 1
handicap). Is this adequate? All -Development Criteria A-2.4 requires a
minimum of two parking spaces for every 3 employees on the major shift.
City Parking Guidelines suggest 4 to 6 parking spaces per 1,000 square feet
or 2 to 3.5 parking spaces per service bay plus 1 space per employee per
major shift.
b. Please show building dimensions on the Site Plan including the distance to
the nearest property line.
C. The subject property is located in the Residential Sign District. In addition
to complying with the City Sign Code, the Planning and Zoning Board will
review the location of all "flushwall" signage that is proposed. The
Residential Sign District will allow only 12" maximum height letters on
individual letter signs, 24" letters are shown. An 18" maximum height is
allowed for the logo, a 30" logo is shown.
d. Please show the location of bike racks on the Site Plan.
e. No entrance signs from the service road into the bay lanes will be allowed.
9. The Building Inspections Department offers the following comments:
a. The site shall be accessible to persons with disabilities in accordance with
Uniform Building Code Section 3103 and UBC Appendix Section 3106.
Provide a designated and marked "accessible route of travel" between all the
buildings on the site and building exits and entrances and the public way
(public sidewalk) is shown. Accessible routes shall comply with ANSI
A117.1-1992 with running slopes no greater than 1:20 and cross slopes no
steeper than 1:50. Where routes cross lanes for vehicle traffic they shall be
designated and marked as a cross walk. Provide parking and signs per
Appendix Section 3107. Parking and access aisles shall comply with ANSI
A117.1-1992 with slopes no greater than 1:50 in any direction.
4. The Light and Power Utility offers the following comments:
a. Apparently the comments from the August 7, 1996 Project Comment Sheet
have not been addressed. The following comments need to be addressed
to properly accomplish installation of electric facilities to the proposed site.
b. There are not adequate access and utility easements on the site to serve
Lots #1 and #2 in addition to serving future tracts in the overall project. Light
and Power will require a 10 foot wide easement on the north property line of
Lot #1 and a 20 foot wide easement along the south property line of Lot #2.
This will allow enough room for the required clearances from electric to water
and gas lines. It will also allow Lot #2 to have it's service wire come from a
transformer located on Lot #1.
C. The 25 foot wide private drive along the east side of the lots will need to a 25
foot wide access and utility easement. This easement will need to continue
to the north through the site per the ODP.
d. It will be very difficult to install street lighting without the advantage of a
vertical curb for permanent location and protection of street lights.
5. The Water Conservation Specialist offers the following comments:
a. The landscape plan shall contain a general note calling for the review and
approval by the City of Fort Collins of any required landscape irrigation
system prior to the issuance of a Building Permit.
b. The landscape plan shall include the total area (in square feet) for each
landscape category. Landscape categories are distinguished by their water
requirements and intended maintenance level. Examples of possible
categories include, but are not limited to, high water turfgrass, low water
turfgrass, low water planting beds, moderate water planting beds, and non -
plant areas (paved areas, etc.). Please refer to the attached Water
Conservation Standards for Landscaping and Irrigation Systems for further
information.
6. TCI of Fort Collins requests a utility easement along North Lemay Avenue and
East Lincoln Avenue.
7. The Poudre Fire Authority offers the following comments:
a. Please provide a fire hydrant at or near both entrances.

Dear Carl,
Staff has reviewed your documents for the Lincoln East PUD, Diamond Shamrock
Convenience Center - Preliminary that were submitted on December 23, 1996, and
would like to offer the following comments:
1. U S West stated the following:
" U S West has a pedestal in the area of the future curb and gutter pan along the
east side of Lemay Avenue, approximately 150 feet north of E. Lincoln Avenue. As
this pedestal appears to be in conflict with the future curb and gutter pan and is the
location which will serve the Diamond Shamrock Center, it is imperative to
determine now if there is a problem between the pedestal and the proposed pan."
2. The City of Fort Collins Transportation Planner stated the following:
"A direct pedestrian connection needs to be provided between the two buildings.
It appears that the current layout is a very hostile pedestrian environment. Are there
any other options?" (Please see Current Planning comments).
3. The Traffic Operations Division offers the following comments:
a. Please show proposed improvements to Lincoln Avenue and Lemay Avenue.
b. Improvements should be coordinated with the Lemay Town Center project
(Wal-Mart) that is proposed at the southeast corner of Lemay Avenue and
Lincoln Avenue intersection.
C. Please provide a set of striping plans for Lemay Avenue and Lincoln Avenue.
