SUBJ: Lake Ann Park Picnic/Recreation Shelter, Consider 1991
iBudget Amendment
. This item was tabled by the City Council on April 22, 1991 to give
1 residents an opportunity to comment on this proposed park
improvement project. The Council also desired additional time to
review details associated with the park shelter prior to taking
Iaction on this item. I believe the coverage received in the May 2,
1991 edition of the Chanhassen Villager fulfills the Council's wish
of ensuring the public is aware of this capital improvement
project. I have not received any negative calls or comments in
this regard. I have had the opportunity to discuss the shelter
with the Mayor and the majority of Council members to ensure that
their questions and inquiries are being addressed. I am confident
1 that the dissemination of information which has occurred since
April 22nd, combined with the attached detailed cost estimations
prepared by VanDoren Hazard Stallings, Inc. in consultation with
Istaff, fulfills the Council's requests of April 22.
I am very aware of the City Council's position on guaranteeing city
expenditures are made responsibly. I have strived to instill this
I theme in the current eight month planning effort now reaching its
culmination. The final estimated budget figures as outlined in the
attached report represent clearly "thought out" expenditures. The
I finished product based on this proposal would provide significant
social and economic benefit to the city and would nurture resident
pride in their park system. Admittedly, the recommended project
scope includes expenditures which are initially greater than other
1 alternatives. However, by recognizing short—and long term
maintenance costs and other future capital costs which would result
from choosing lower up front costs, it becomes apparent which
1 alternatives are "cost saving". In short, an initial wise
investment will clearly eliminate the expenditure of significant
dollar amounts each year following completion of the project.

However, as recognized by the City Council, cost reductions are
always possible. Potential areas which could be cut have been
' identified in Mr. Koegler's report. If it is the pleasure of the
Council, they may elect to recommend these reductions. Other than
the elimination of the cedar shakes, this action would result in a
' significant visual change, these potential cost reductions are
relatively painless. Lastly, it is important to again point out
that the funding sources for this project would be the park/trail
acquisition and development and utility expansion funds. All
' assets accumulated in these funds are generated through fees
collected at the time of building permit issuance for residential,
commercial and industrial development. These funds are established
' per Chanhassen City Code, stating it is the city's desire to
provide for the welfare of its residents through the construction
of public facilities and provision of public services.
' With this, it is recommended that the City Council amend the 1991
Park Acquisition and Development Capital Improvement Program to
include an additional $90, 000 ($110, 000 is currently budgeted) to
' be transferred from the gam]- Park/Trail Acquisition and
Development Fund, authorize the expenditure of up to $100,000 from
the Utility Expansion Fund, and authorize preparation of plans and
' specifications for the Lake Ann Park Picnic/Recreation Shelter.

' Manager's Comments: Costs associated with this project are
exaggerated by the inclusion of sewer and water. Justifications to
' install sewer and water to the 150 acre park site exists with or
without the shelter building. Having the ability to provide water
service to the ballfield's concession stand and having water
faucets/fountains available for public use are being continuously
requested. Similarly, the city would not permit either a well or
septic system for any type of development where municipal sewer and
water were available and which served 10, 000-20,000 people per
' year. Again, the magnitude of the project, i.e. providing sewer
and water to a 150 acre site is a significant project in and of
itself.
' The current estimate of $150,000 to $165,000 for the shelter
building is reasonable given the multiplicity of uses proposed for
the structure, i.e. public restrooms, changing area, concessions,
storage/rental, picnicking and community gatherings. The cost is
actually less than the Lake Susan Shelter - $225, 000 (albeit that
figure does include the costs for the municipal well associated
' with that facility) .

Similar to the Mayor and most Council members, I attended most of 1
the Park and Recreation Commission meetings where the proposed
shelter was discussed. The Park Commission looked to and has ,
already made cost reductions.
I would ask that the City Council approve the Park and Recreation
Commission's recommendation to amend the budget and to prepare
plans and specifications for this project.

MEMORANDUM
' TO: Todd Hoffman
FROM: Mark Koegler
' DATE: May 14, 1991
' SUBJECT: Lake Ann Park Picnic Shelter
As a follow-up to our recent discussion, we have refined the cost projection information for
' the proposed picnic shelter building at Lake Ann Park. Major project costs involve the
construction of the building and the installation of utilities to serve the structure. The
following is a breakdown of projected utility costs:
' Water
' Providing water to the site can be accomplished in one of two ways, either through the
extension of an existing watermain or by installing a well.
' Option 1 - Watermain Extension
' This option involves the extension of the existing watermain that is located along the
southern boundary of the park abutting TH 5. Extension of the watermain would entail the
installation of a six inch water line from TH 5 to the existing softball concession building and
the installation of a new two inch line serving the proposed picnic shelter. This configuration
would make water available in the future should the City decide to install irrigation in any
of the ball fields. The total estimated cost of the new watermain construction is $36,400.00.
' Option 2 - Well Installation
' This option includes the drilling of a new well in the vicinity of the proposed picnic shelter
including all required controls, hydro pneumatic tank, etc. The well which would be
designed to serve only the new building has an estimated cost of $6,000.00.
' Comment
1 In providing water to serve the new building, water quality and quantity need to be
considered. Water quality can best be ensured through an extension of the municipal water
system rather than through the use of an on-site well. On-site wells are subject to potential
' ground water contamination and require constant monitoring when used in public buildings.

The extension of the municipal watermain can also guarantee the quantity of water available
for use in the proposed picnic shelter. Quantity is an important issue in providing fire
protection for the new building. Option 1 would enable the installation of hydrants to serve
various areas of the park.
Option 1, the extension of the existing municipal water system is the recommended
alternative for providing water to the proposed Lake Ann Park shelter. This option
represents a good long term investment for the City because it ensures both the quality and
quantity of water required for the proposed building. The estimated cost of Option 1 is
$36,400.00.
Electrical '
When the lighting was installed in baseball field #1, provisions were made for the future
extension of electrical service into other portions of the park. An electrical line is proposed
to be installed from the existing light pole north of the backstop area to the existing picnic
shelter and then on to the proposed picnic shelter. The projected cost of the electrical
installation is $10,400.00.
At the present time, we are working with NSP to examine the potential of providing street
lighting along Lake Ann Park's internal roadway system. Such a system could also make
power available to both the existing concession building and the proposed shelter.
Information on this option should be available for presentation at Monday's City Council
meeting.
Sanitary Sewer ,
The proposed picnic shelter building will have complete restroom facilities necessitating the
need for sanitary sewer service. Waste treatment can be handled in the following ways: ,
Option 1 - Holding Tank
This option involves the installation of two 1,500 gallon holding tanks near the existing lower
level parking lot. Effluent would be pumped from the proposed building through a small
force main to the tank location. The total estimated cost of this option is $14,300.00. ,
The holding tank would need to be pumped by a private contractor on an as needed basis.
Based upon estimates of beach usage, it appears that the tanks may need to be pumped at
least twice per week throughout the summer season. At $200.00 per pumping, the total cost
over the summer is estimated at approximately$5,200.00. As use of the beach continues to
rise in future years and as metro waste fees continue to escalate,seasonal pumping costs will
rise proportionately.

IOption 2 - Drainfield
I The waste treatment needs of the proposed picnic shelter could be handled by an on-site
septic drainfield system. Assuming that soil conditions are adequate,waste could be pumped
from the building to a drainfield on top of the hill. The cost of this option including the lift
I station pump, a small forcemain and the drainfield laterals is estimated
at $19,180.00.
I The primary concern in considering the drainfield option is the potential for system failure
and the leakage of untreated effluent into Lake Ann. In order to prevent this from
occurring,the City would have to implement a thorough maintenance program and designate
Ia suitable, alternate drainfield location should the initial lateral system fail in the future.
Option 3 - Greenwood Shores Connection
I This provides option rovides a direct connection to Chanhassen's municipal sanitary sewer collection
P P rY
I system. It involves the installation of a lift station and construction of a forcemain system
around the east side of Lake Ann with a connection to the Greenwood Shores lift station.
The projected cost of this alternate is $33,100.00.
IOption 4 - TH 5 Connection
I Like Option 3, this alternative also provides a direct connection to Chanhassen's sanitary
sewer system. In this case, the system consists of a lift station and a combination
forcemain/gravity sewer system connecting to a existing line abutting TH 5. The projected
1 cost of this alternative is $50,000.00.
Comment
IThe alternates for providing sanitary sewer service to the proposed picnic shelter range from
$14,300.00 to $50,000.00. Both the on-site system and the holding tank options present
I lower cost methods of providing required services but do so at a higher risk to the
environment and in the case of the holding tank, with higher annual maintenance costs.
Connections to the existing municipal system at either Greenwood Shores or along TH 5
I represent long term, permanent solutions to providing required sanitary service. Therefore,
the connection to Greenwood Shores with an estimated cost of $33,100.00 is the
recommended sanitary sewer alternative.
IBuildin g Costs
IIn recent discussions on the proposed picnic shelter, additional information was requested.
The requested information includes: 1) provide a more detailed cost estimate, 2) examine
potential cost reductions, and 3)compare the estimated square footage cost of the proposed

shelter to comparable buildings. Cost estimates at this stage of any building project should I
be considered preliminary since they are based on a concept plan rather than on detailed
building plans. Despite this fact, it is possible to provide more detailed cost estimates on
I
the various components of the project.
The following is a cost estimate for the proposed Lake Ann picnic building based on the

these identified items, the shelter ranges in cost from $164,463.00 to $146,663.00.
With a total estimated building cost of$164,463.00,the cost of the building equates to $60.25 '
per square foot. Utilizing nationwide building survey information, it is possible to compare
this figure to comparable public structures. Community center buildings without specialized
athletic equipment have an average cost of $73.65 per square foot. Rest area buildings
commonly being built by midwestern departments of transportation are currently averaging
$122.25 per square foot for one story structures and $149.00 per square foot for two story
structures.
