Basin B1 is draining into the Cooper Slough. The requirement that should be met is to
show no adverse impact downstream and no rise should be caused in the downstream
floodway at Prospect Road.

The TIS is acceptable for the ODP submittal. As phases come into the process,
additional TI5 analyses will need to be completed. The project on a whole generates
more than 10,000 trips/day and I will more than likely require the TIS to go west as
for as Timberline/Prospect. If the uses are I-25 related, the APF and
Timberline/Prospect may need not be addressed. However, the interchange itself has
APF issues as well as safety issues. Any phase will need to examine the issues in more
depth and make improvements to the interchange. I do not believe it is acceptable to
create another "I-25/SH392 scenario" such as Windsor is experiencing.

CDOT will need to review and comment on the proposed overall development plan. There
will most likely be multi -modal improvements necessary to the Prospect interchange as
individual PDP's are submitted. Please consult CDOT further to address and coordinate
their future plans and the upcoming environmental study regarding the I-25 corridor.
FYI - future development along Interstate 25 will need to take into account the
interchange improvements. CDOT has asked for sufficient space to construct a design
similar Harmony Rd. interchange.

Please be aware that as the PDP proposals are submitted that more detailed analysis of
the transportation system and impact analysis will be required. This may lead to off
site improvements, such as bicycle or pedestrian connections to surrounding
destinations as identified in the Overall Development Plan's TI5 (i.e. neighborhood to
the west).

JR Response: Noted . Discussion of the amended floodplain can be found in the last
paragraph of section 3 of the Drainage Report.
There needs to be sufficient notes pertaining to the floodplain and regulations on both
the Overall Drainage Plan and Overall Development Plan sheets. Please add the
following notes to the plans:
Any residential structures in the floodplain must have the lowest floor including
basement or crawl space elevated 18" above the most restrictive 100-year flood level.
Any non-residential structures in the floodplain must either have the lowest floor
including basement or crawl space elevated 18" above the most restrictive 100-year
flood level or be flood -proofed 18" above the 100-year flood level.
Critical facilities are not allowed to be built in the most restrictive 100-year floodplain.
Please see Chapter 10 of City Code for the definition of critical facilities.
A floodplain use permit and $25 permit fee will be required for each structure that is
built in the floodplain. To obtain a CO, an elevation certificate or flood -proofing
certificate will be required to be submitted and approved.
A floodplain use permit and $25 permit fee will be required for any construction
activity in the floodplain including construction of the detention ponds and any roads.
All utilities within the most restrictive 100-year floodplain shall be designed to
minimize or eliminate infiltration of floodwaters into the systems and discharge from
the systems into floodwaters.
In the report please discuss the erosion buffer limits and how they will affect the
design of the bridge crossing and any other drainage features.
At time of PDP please use the Floodplain Review Checklist to aid in the development of
a complete submittal.

Floodplain Management Comments
Susan Hayes
The floodway for the revised Cooper Slough/Boxelder floodplain has been adopted and
will be applied to this site as it develops. Please remove any reference to "proposed"
floodway on the drawings and in the report.
JR Response: Done
Show both the current FEMA floodplains (including Cooper Slough) and the revised
floodplain/floodway on the drawings. It's not clear on the ODP plan whether the
floodway line is shown in its entirety. Please use the work maps to correctly site the
Cooper Slough floodplain.
JR Response: Done
Since there are two regulatory floodplains (City and FEMA) analysis for both
conditions shall be required at time of design of any facility in the floodplain. Because a
floodway is not mapped in the FEMA floodplain, the floodplain is considered "no -rise".
This means that you can not cause a rise in the flood level off of your property without
obtaining easements from affected property owners.
JR Response: Noted
Any changes that are made to the no -rise floodplain or in the recently adopted
floodway (fill, plantings, construction of buildings, culverts, channels, bridges,
bikepaths, etc.) will need to be modeled by a registered professional engineer to
document no -rise. A $300 fee is required if hydraulic modeling is necessary. Please
use the City's Floodplain Modeling Guidelines for the preparation of this analysis.
Please include the benchmark number and elevation being used for the site.
On Sheets 2 and 3 for the Overall Development Plan, what does "Future Extents of
Amended Floodplain Per JR Engineering" mean? This is not discussed in the report.
Please clarify.

It seems that the detention ponds were sized using the rational method. At PDP
SWMM modeling will be required, this could have a significant impact on the size of
these ponds.
JR Response: Noted
The report proposes to release drainage waters from the detention ponds at rates
matching the 10 and 100 year storms. It is recommended by the master plan that a 2
year release be done. The matching of the hydrograph in the 10 year storm and the
100 year storm as proposed would only be acceptable if it can be demonstrated at PDP
stage that no adverse conditions are caused by such a release.

Topic: Ditch Easement
Number: 12 Created: 9/12/2003
The Lake Canal is located along the north side of the property. The ditch company is
requesting that an easement be designated for the canal right of way. This easement
should be 50 feet from the centerline of -the canal, for a total of 100 feet wide. If
the Canal is along the property line then only 50 feet would need to be provided by this
development. Crossing agreements would be needed at PDP for any bridge or utility
crossing of the canal.

JR Response: Easements will be provided on the plat with the PDP submittal
e. Any relocation, cutoffs, and/or installations will be at the developer's expense,
in accordance with the extension policy on file with the Public Utilities
Commission.
Most of these comments obviously relate more to future PDP submittals and
development review.

Per 3.6.3 an additional connection out to the frontage road, north of the existing
motorcycle dealership is needed (unless rendered as specified in the code.) City Staff
has concurred that there is support in not requiring this connection. The applicant
should present rationale on the ODP that such a connection is infeasible and/or submit
an alternative compliance request to formalize meeting this section of code.
Number: 23 Created: 9/17/2003
Please add the following notes on the ODP (per 2.3.2(H)(4) of the LUC):
- The frontage road and Prospect Road does not meet current City standards.
- Traffic functionality of the frontage road at Prospect Road currently does not meet
acceptable level of service.
- Traffic functionality of the northbound I-25 off ramp at Prospect Road currently
does not meet acceptable level of service.
- The Prospect Road overpass over I-25 does not meet current City standards.
- The applicant will work with the City and CDOT with respect to transportation
improvements in the area.
- The City may review classification of the frontage road at the time of a PDP.
- No vehicular access points to Prospect Road will be allowed for the parcel east of the
frontage road.
- Redesign/reconfiguration of the I-25/Prospect Road interchange may result in an
impact on the development of the site and may require additional right-of-way.
- Off site improvements may be required at the time of a PDP in order to meet level of
service for all modes of transportation.
- Site distance easements may be required along the public roadways at the time of
PDP review.

Per Section 2.3.2(H)(4) of the LUC, an ODP shall conform to the Master Street Plan
requirements and the street pattern/connectivity standards both within and adjacent
to the boundaries of the plan as required pursuant to Sections 3.6.1 and 3.6.3(A) - (F)
of the LUC. An alternative compliance request is needed at this time to address the
lack of proposed street connections to the east, to the Frontage Road. City staff will
be supportive of this request. The lack of street connections to the west will be dealt
with through Section 4.1(E)(1)(b) of the LUC.

Mike Scheid of the East Lorimer County Water District provided comments on a red -
lined set of utility plans. These plans were given to Cityscape Urban Design following
the staff review meeting held September 10, 2003.
JR Response: Discussions with Mike Scheid indicate that a connection needs to happen
to provide adequate water supply. A water line connection will be provided within an
easement to be used for utilities only and not for pedestrian or vehicular traffic.

Len Hilderbrand of Xcel Energy (Public Service Company) offered the following
comments:
a. Public Service Company (PSCO) has 4" gas mains along the north side of East
Prospect Road and the east side of the Frontage Road to serve the proposed
development area.
b. PSCO will need adequate easements (15' wide) along both sides of all interior
streets.
JR Response: Easements will be provided on the plat with the PDP submittal.
C. PSCO also has an existing overhead electric distribution line along the north
edge of East Prospect Road. This will be required to be undergrounded (with
development of the Interstate Land property) at the developer's expense.
d. PSCO will need a minimum 25' wide utility easement along the south edge of this
development adjacent to the East Prospect Road right-of-way.
