RE:
777 ute Avenue/Final Plat
DATE:
September 12, 1988
----------------------------------------------------------------
----------------------------------------------------------------
SUMMARY: The Planning Office recommends approval of the. 777
(formerly 771) ute Avenue Final Plat with conditions.
APPLICANT: Kent Shodeen
REQUEST: Approval of the 777 Ute Avenue Subdivision Plat.
LOCATION: 777 Ute Avenue.
HISTORY: The 777 ute Avenue Townhomes Subdivision was approved
as a 1987 Growth Management project. It was approved as a 9 unit
project on January 19, 1988 at Preliminary Plat by the Planning
commission with the conditions as listed in the staff comments
(below) .
REFERRAL COMMENTS:
1. Engineering: In the attached memorandum Jay Hammond of the
Engineering Department makes the following comments:
1) As I am not aware of the Parks Department involvement
in the application, I would note the existence of 3
large cottonwoods on the west property boundary and
suggest verification of their proposed removal.
2) The plat and agreement as submitted are quite complete
and respond to our GMP and subdivision exception
requests including dedication of the Aspen Mountain
road, improvements to Aspen Mountain road and ute
Avenue, improvement district language and sidewalk
improvements. We would recommend approval of the final
plat and exception agreement subj ect to the following
modifications prior to recordation;
a) Extension of the southeast storm sewer inlet to
intercept the spring across the road to the south
at its source: We will coordinate sizing and
design details with the applicant's engineers.
,--
.-..
b) Modify the subdivision exception agreement
language on page 5 to state '.' "which estimated
cost, as approved by the City Engineer,"...
c) Indicate handicap ramps on sidewalks as
appropriate.
2. city Attorney: The legal issues will be coordinated with
the City Attorney prior to the meeting.
STAFF COMMENTS:
The Preliminary Plat for the 777 ute Avenue project was approved
with the conditions as follows:
1. Rezoning: On January 19, 1988 P&Z recommended approval of
the requested rezoning of Lots 15B, 16 and 17 of the ute
Addition and Lot 41, section 18, Township 10 South, Range 84
West, City of Aspen from the L-l zone district to the L-2
zone district.
Response: The rezoning took place as a result of the
creation of the LTR zone district which was established when
the new code and zone district maps were adopted in April of
this year.
2.
Subdivision:

On January 19,
approval for the
project subject to
1988 P&Z gave preliminary
771 ute Avenue Townhouses
conditions that follow:
a. A Final Plat application shall be submitted according
to the requirements of sections 20-11 and 20-12 of the
Municipal code including:
1. A detailed storm drainage plan shall be submitted.
Response: The storm drainage plan was s.ubmitted. The
plan has been modified since the Preliminary Plat
reVlew. The modification includes a detention area
located at the north east corner of the property (see
map, sheet 4). This creates a water feature for the
project and gives the north east corner of the
property more of a landscaped/park like appearance.
2. Survey corrected with regard to the location and
ownership of the Aspen Mountain Road and lot area.
Response: The
ownership of the
the public a 10 I
applicant proposes to resolve the
Aspen Mountain Road by dedicating to

the final plat.
3. site/landscape plan showing site improvements
described in the 771 Ute Avenue GMP application,
including but not limited to vegetation to be
planted, irrigation system, pedestrian areas, bike
rack, benches, and landscape and walkway lighting.
Response: The applicant has supplied a landscaping
plan which generally meets the requirements imposed at
conceptual and preliminary plat. However, the plan
does not indicate the irrigation system, walkway
lighting or verification from the Parks Department that
the 3 cottonwoods on the west property boundary can be
removed and will be adequately replaced. All these
elements must be incorporated into the landscape plan
and subdivision improvements agreement. In addition the
subdivision improvements agreement only guarantees the
landscaping improvements in the public right of way. It
does not bond for the entire site landscaping
improvements.
b. A statement of subdivision and improvements agreement
shall be submitted as part of final plat. Included in
this document shall be a development schedule and
appropriate financial guarantee for all site
improvements and off-site improvements described in the
771 ute Avenue GMP application including but not
limited to storm sewer, pavement of part of Aspen
Mountain Road, curb and gutter, and fire hydrant.
Also included shall be agreement to join any
improvement district formed that encompasses this
property.
Response: The applicants have submitted a subdivision
improvements agreement. This agreement notes the proposed
time schedules for construction of the project as well as
gives financial assurances for the project improvements.
The subdivision improvements agreement includes all
necessary assurances with the exception that the irrigation
system and walkway lighting have not been included in the
agreement and that the agreement only bonds for the
landscaping in the public right of way.
c. An agreement for emergency access to this project
through the Aspen Alps drive-through from s. Spring
street to ute Avenue shall be submitted.
Response: An existing agreement between the Alps and the
City allows for emergency vehicle access.
d. The applicant will estimate the value of installing the
3
~
.~
70 feet long 6 foot wide sidewalk opposite the project
on ute Avenue and agree to contribute this sum to the
city for pavement of this sidewalk, repairs to the ute
Avenue trail or acquisition of a missing trail right-
of-way along the ute Avenue trail. This sum of money
will be given to the City prior to the issuance of a
certificate of Occupancy and will be held in an
interest bearing account until the City formally
commences that project which the City determined is
most needed from the alternatives stated. If no such
project is begun after ten (10) years after the
submission of the application, then the original
contribution and interest payments will be returned to
the applicant.
Response: This has been adequately handled in the
subdivision improvements agreement.
e. Allocation of eight residential units from the Growth
Management Quota must be granted by City Council in
conjunction with Final Plat approval, or Final Plat
shall not be approved.

condominiumization documents.
Response: The applicants are not requesting
condominiumization at this time.
3. Employee Housing: The P&Z recommended on January 19, 1988
acceptance of the cash-in-lieu payment for the equivalent of
12 low income employees, as calculated at the time of
building permit application, and shall be paid to the
Housing Authority prior to issuance of any building permit.
Response: The Housing Authority has indicated in their
review that the applicants employee housing contribution is
calculated to be $300,000. The applicant has committed to
this figure in the Subdivision Improvements Agreement.

the Lodge at Aspen project shall expire. The 777 Ute Avenue
Townhomes shall be built in two phases, with 2 units being built
in 1988 and 6 units being built in 1989.
In summary the Planning Office feels the Final Plat application

meets the requirements of the previous approval and final plat
requirements if the conditions as listed below are adequately
met.
RECOMMENDED MOTION:

conditions:
1. The City Attorney shall review and approve the
Subdivision Improvements Agreement language.
2. The Subdivision Improvements Agreement and plat shall
be amended to include an irrigation system and walkway
lighting.

ISSUE: The applicant proposes to make payment in lieu which was

most recent submission is $300,000 in lieu of housing 12 low
income employees.
HOUSING RESPONSE: 12 x $25,000 (low income contribution) is
equal to $300,000 and appears appropriate under the 1988 Employee

Please note that the address of the project has been
changed from 771 to 777 Ute Avenue. The new address has
been reviewed and approved by Marta Steinmartz, the
Sheriff's Office employee in charge of the City's address
system.
The final plat is consistent with all representations of
the Applicant's preliminary plat submission with the
exception of minor modifications to the project's drainage
system and landscape plan. As Sheet 4 of the Final Plat ~/
illustrates, a detention area has been located near the
northeast corner of the project site. While the pos-
sibility of this facility was discussed in the Applicant's
GMP application, it was not reflected on the original site
plan.
As the Landscape plan illustrates, minor modifications in ~_
the location of plant species are required to accommodate
the facility. No reduction in the overall quality of the
project's landscaping, however, is proposed. In fact, the
project should benefit from a more open view to Glory Hole
Park and from the inclusion of a proposed water feature.
Runoff from an exposed spring located near the property's
southeast corner will be piped through the detention area.
With respect to the Subdivision Agreement, please note
that the Applicant proposes to resolve the Aspen Mountain
Road ownership issue by dedicating to the pUblic the ten
(10) ;! road easement referred to in the original GMP
application. Also note that the agreement provides for
the so-called Ute Avenue trail/sidewalk escrow, the
Applicant's cash-in-lieu employee housing contribution,
the phasing of the project, financial assurances for
pUblic improvements, and a park development impact fee,
all of which were required as conditions of preliminary
plat/GMP approval. Condominiumization of the project is
not requested at this time.
As the attached agreement between the City and the Aspen
Alps Condominium Association indicates, emergency vehicle
access was retained over . the portion of ute Avenue which
the City allowed the Alps to close to Vehicular traffic.
Apparently, Steve Burstein was unaware of this document
when he recommended that the Applicant obtain an agreement
for such access through the Alps property. The City's
prior agreement provides adequate access from South Spring
Street and, therefore, should be sufficient to address
r-.
~
Ms. Cynthia Houben

Steve's concerns. It should
vehicle access through the
give the height of the Alps'
also be noted that emergency
Alps is physically impossible
entryway.
Should you have any questions, or if I can be of any
assistance, please do not hesitate to call. As the
Applicant wishes to commence construction as soon as
possible, any help you might provide in expediting the
review of our application would be sincerely appreciated.

RE: nrainaqe and Grading Plan, 771 Ute ~venue
Dear Jay:
Please let this letter serve as a report and detailed discussion re-
garding the drainage requirements for the above-referenced developnent.
The develop!1ent will encompass rots 15B, 16 and 17 of the Ute Addition
to the Townsite of Aspen. The existing oond it ions on site oonsist of a
one-story, MXX:l and masonry building of approximately 1,000 square
feet. The remaining area on the lot is in an undeveloped state with
the exception of driveway and sidewalks. We have calculated the o::>m-
posite runoff ,coefficient for the existing site to be. as follows:
Cc 10 = 0.2931
Cc100 = 0.3524
The proposed developed oondition will introduce impervious surfaces
throughout the site. The roof area will introduce approximately 7500
square feet of impervious area. The sidewalk associated with the
developnent will introduce approximately 2200 square feet of impervious
area. The remainder of the developnent will be of landscaped, and will
be equivalent to, undeveloped oondition. The comlXlsite runoff coeffic-
ients for the developed oondition are as follows:
Ccl0 = 0.6561
Ccl00 = 0.7168
Utilizing a ten-minute duration $torm (time of ooncentration = 10 min-
utes), to determine the rainfall intensity for ooth the ten-year rain-
fall event and lOo-year rainfall event, we have been able to estimate
the historic and developed flows from the site. These flows are as
follows :
010 historic = 0.334 cfs
0100 historic = 0.580 cfs
010 developed = 0.747 cfs
0100 developed = 1.180 cfs
Based upon the flows (developed and historic) calculated, we have
determined the recharge volume for the site is equal to 247.9 cubic
feet, and the required detention volume is equal to 359.8 cubic feet.
We are proposing to handle the increa$ed flow rates from the site in
the following ways:

the site with a controlled outlet. A drywe11 will be located in the
bottom of this PJnd which will be designed (from a vollDlle stand-
point) to recharge the groundwater at. the specified vollDlles. The
overall Drainage Plan is proPJsing to capture all the runoff to the
roof area of the building into an 8" PVC line located on the east
lot line of the development. This 8" PVC line will be taken to the
detention pond where it will be discharged. At the detention PJnd,
the required detention vollDlles and recharge volumes will be achieved
with the use of . the drywell located in the rottorn of the detention
pond and with the use of the controlled outlet. The controlled
outlet will be a 6" PVC line which will be discharged in the storm
sewer inlet at the northeast corner of the site. We have found
that, by collecting and discharging all of the runoff created on the
roof of the structure in the detention pond, we can achieve the
requirements of recharge and detention along with historic flow rate
release for the site. As can be observed from the attached Drainaqe
and Grading Plan, we are proPJsing to allow the water on the back
side of the building (south side) to flow from a east to wes!: direc-
tion, and discharge in the southwest corner of the property onto the
street. The sidewalk drainage located on the east side of the prop-
erty will be allowed to discharge into the City I s storm system (curb
and gutter). The remainder of the site will be graded. to direct
flows to the detention pond.
The existing City storm sewer system will be extended up Aspen lIbuntain
Road. The extension will be from the existing storm drain at the o::>r-
ner of ute and Original .to the southeast oorner of the property. A
catch basin will be installed on the end of the line to capture the
spring flow and runoff from Aspen Mountain Road. We have shown an 18"
storm drain. This is consistent with the City'sPJlicy of a minimlDll
18" size for storm drain facilities. We have not had a chance to mn-
firm that sizing with your office, but will do so during the review
process.
There currently exists drainage problems in front of the property from
the Ute Avenue/Original Street intersection westerly to the Aspen Alps.
In order to try addressing that, we have indicated we would propose
lowering the street grades in this area so that any surface water
drainage will be directed. down ute Avenue. At the present time, water
generally flows westerly along Ute Avenue and causes nuisance flooding
throughout the Aspen Alps green area. With the re-configured. Grading
Plan, that situtaion should be alleviated.

In sumnary,the majority of the storm water generated on site will be
collected and discharged into a detention pond and recharge area lo-
cated in the northeast wrner of the property. '!he drainage pond will
be drained by a controlled inlet into the eKisting storm water drainage
system. '!he storm sewer system will be extended up Jlspen r-buntain Road
to the southerly edge of the property. Portions of Ute Avenue will be
lowered in order to control the remaining surface water to the south of
the property. We feel that, if this Drainage Plan is constructed as
detailed in this letter and on the attached plan, the Drainage Plan
will be in <XJIIIpliance with the drainage requirements outlined in the
City of ./\spen's Municipal Code. If you have any questions, please do
not hesitate to call.
