Recap of Parks Meeting with City Council
Minutes of June 19, 2006
The commission•
discussed the four questions with the City Council. The commission heard that at this time
the City Council is open to all possible options when trying to address problems. Not only the ideas listed but
any other ideas that arise. The City Council requests that as we do several things when addressing funding
issues. We should always include a comparison to some other comparable communities, like ours, and how
they are addressing similar situations. We should list our recommendations with how much is needed, what is
needed now, what are the options along with our recommendations of what should be tried first.
The commission discussed the on going capital needs of the Community Center. We should have been more
active over the years on advocating some kind of fund being set aside each year to address capital items as
they wore out. It seems now is the time to start addressing this.
To; address long-term parks needs we acknowledge that our funding source was originally set up for park
acquisition and development. Since that time we now must address the missions that parks have evolved into;
community centers, trails, open space and park redevelopment. We need to review our parks comprehensive
plan modifying it for projects that are finished, what is left to be done, new things that need to be added and
what current priorities should be. The commission should reevaluate this plan every three to five years. As part
of the process we need to acknowledge what we have finished and what we have not.
This process should list what needs to be done to keep us just at redeveloping parks, add what is needed for
community centers, the amount for trails and then the amount for open spaces. Then we need to recommend
funding levels and options.
Commissioner Frank approved the above minutes, but wants the minutes to reflect that he did not feel there
was a discussion with the Maplewood city council and desires that a future meeting be established if possible.
The commission indicated as a whole their desire to have a better understanding of council direction and their
perspective and vision as it relates to the Maplewood Parks and Recreation Department, parks, open space •
and trails.

3. APPROVAL OF MINUTES
A motion was made by Commissioner Gran, seconded by Commissioner Roman, to approve the May
15, 2006 meeting minutes as presented. The motion passed, 7 ayes, 0 nays.
4. COPAR DEVELOPMENT
Director Anderson reviewed the Copar proposed development and stated that the commission
previously reviewed a proposed project entitled Carver Crossing with 300 units including two senior
four-story complexes. The Copar property is located in southern Maplewood north of Carver Avenue.
The commission formally adopted a position statement at their May meeting which in turn was formally
adopted as part of the May 15 meeting minutes.
• Staff indicated that Copar has since modified its proposal and reduced the number of units to 192,
which would all be single-family, detached homes. Staff said that part of the rationale for the reduction
by Copar was that this proposal would require only a three -vote majority as opposed to four votes for
zoning changes by the city council.
Director Anderson indicated that he had met with representatives from Copar regarding a new park
development proposal and/or concept. The proposal from Copar Development was six fold:
a. The Maplewood Comprehensive Plan, Park Plan and Mississippi Critical Area Plan do not identify
any portion of the Copar property as parkland.
b. The 2006 park dedication fee for new single-family homes in Maplewood is $3,060 which was
increased February 13, 2006 by the city council from $1,530.
c. The 2006 park dedication fee obligation for the revised 192 single-family homes for Carver Crossing
development plan is $587,520.
d. Interested parties and residents have voiced concerns about the lack of public park and trail
improvements within the proposed developed area.
e. Copar is proposing the city allocate $250,000 of the city's $587,520 park development fees for the
192 -unit home development. They further stated that the purpose of the allocation would be for
public trail and park overlook improvements.
f. In addition to the established park dedication fee of $587,520, Copar would conditionally match the
city's $250,000 allocation with an additional dollar -for -dollar or like in-kind park trail improvements
valued up to $250,000. The dollar -for -dollar match was conditioned on maintaining the continuity of
the current 2.7 single-family homes per acre as proposed.
Director Anderson indicated that he supports the Copar proposal. He further stated that there is a
correlation between the proposed Copar property and the Legacy Village development including
wetlands, floating boardwalk, and the need for a picnic and tot lot area. Staff indicated that in addition to
• a more "actively developed" park area, the concept of a scenic overlook needs to be pursued as well.
Staff felt that the open property next to Lot 25 (open due to steep grades) could be an ideal location for
a "floating" observation tower to be constructed off a large pole and/or piling.
Staff also reviewed with the commission the important role that P.A.C. dollars play in the acquisition,
development and restoration of city parklands. Staff indicated that over 98% of all park monies come
from P.A.C. fees and that the residential portion of the P.A.C. fee is being reduced as the city becomes
more developed.
Staff requested the commission review their May 15 motion to reflect the new Copar Development
proposal as well as clarifying the status and important role that P.A.C. monies play for the city.
The end product was that Ramsey County identified 8.2 acres of severe slopes that should be protected
and Ramsey County would be willing to manage any Copar lands that the city would dedicate and/or
convey to the county.
Commissioner Christianson indicated that approximately 20 years ago the city pursued acquisition of
the Copar lands which at that time were owned by the Schlumka family. Senator Jerome Hughes was
involved in that acquisition and the city did not finalize the purchase.
Resident Ron Cockriel indicated that he and Commissioner Peterson met with Victoria Reinhardt,
chairperson of the Ramsey County Board and representatives of the Ramsey County Parks and
Recreation staff on July 13. The end product was the identification of 8.2 acres of severe slopes that
should be protected. He further said that he desires to see the Copar land remain in public ownership.
He said that trails should play an important role in the final development.
• Mr. Cockriel said that the city council on July 10 did not approve authorization to prepare an
Environmental Impact Statement. The motion failed 3-2. He indicated that there is a 30 -day appeal
process for this and that if the E.I.S. is upheld, it could bring about a 280 -day delay for the developer
and require the developer pay the cost for the study which would be up to $100,000. Director Anderson
said that representatives from Copar stated the company position is to sell only the entire parcel and not
smaller acreages.
Commissioner Peterson requested clarification on where the 37% of open space is located. Staff said it
is all the land highlighted in gray. Chairperson Fischer outlined the number of existing recreation
amenities including Pleasantview Park, Carver Park, and the open space property within proximity of
this property. Commissioner Peterson indicated the important role that overlooks could play within the
city park system and outlined her observations of the Smokey Mountains.
Commissioner Christianson questioned any potentiality of federal funds saying he does not believe
there is any realistic opportunity. Commissioner Peterson and Ron Cockriel felt that federal funds could
be available.
Chairperson Fischer stated "tongue in cheek" that he would support a 20 -story tower with the remaining
lands to be left in public domain.
A motion was made by Chairperson Fischer, seconded by Commissioner Christianson, to modify the
May 15, 2006 motion to clarify the term "acquisition" for a vista to mean that the city should pursue a
vista but not utilizing P.A.C. monies and that the P.A.C. monies be used solely for development of hard
scapes and/or park improvements and not for land acquisition. The motion further stated that the
commission supports and endorses the developer's offer of a $250,000 match for public park
improvements with the understanding that the city would utilize $250,000 of the $587,000 P.A.C.
monies within this related project and furthermore, strongly encouraged the city council to pursue
development options with the developer of higher density levels to include increased building height to
preserve greater public land acreage. Furthermore, that a trail corridor be established along the eastern
edge of the property to Carver Avenue for a future trail extension to city open space, Pleasantview Park
and Carver Avenue and that city staff work with the developer to create a master plan that would
ultimately be reviewed by the commission and city council for their consideration. The motion further
stated that the commission supports and endorses the developer's offer of a $250,000 match for public
park improvements with the understanding that the city would utilize $250,000 of the $587,000 P.A.C.
monies within this related project and furthermore, strongly encouraged the city council to pursue
development options with the developer of higher density levels including increased building height to
preserve greater public land acreage and furthermore, the commission recommended that the land
adjacent to 1494 be considered as a cluster development. The motion passed, 6 ayes and 0 nays.
(Commissioner Gran left the meeting at 8:30 p.m. during the discussion.)
5. CITY COUNCIL TOUR
Chairperson Fischer briefly reviewed the June commission/city council tour. He thought the tour was
positive, but was disappointed with the Council's response to the specific questions. Commissioner
Frank indicated his strong displeasure with the council's lack of vision and goal identification for the
commission. Staff said that the commission should be pleased as they were the first and to his
knowledge the only commission that has had an opportunity to meet with the city council one on one.
6. COMMISSIONERS' COMMENTS
Commissioner Frank said that the department's youth softball tournament will be held in Little Canada
this weekend. Commissioner Roman said he received many positive comments on the 4th of July
celebration. Commissioner Gaoly highlighted the dragon festival and encouraged the city to become
more involved regarding diversity issues in the future. She furthermore stated she believes there are a
number of issues relating to acceptance and understanding of cultures that relate to city parks and that
the city council needs to better understand and become an active part in developing the solution.
Chairperson Fischer said that the Community Outreach Commission that replaces the past human
resource commission should assist in coordinating that process as well.
Resident Ron Cockriel said that he feels the city council needs parks and recreation commission input
and direction more now than ever.
7. DIRECTOR'S REPORT
Parks and Recreation Director Anderson reviewed the monthly update including comments regarding
the proposed Ramsey County trail map that was included in the packet. He also said that parking on
Summer Avenue west of Western Hills Park is a significant issue being raised by the residents. He
further said that city staff, commission and council need to be aware if there are to be modifications in
off-street parking that affect the remaining park sites that would be impacted.
10. ADJOURNMENT
The meeting was adjourned by consensus at 9:12 p.m.

MEMORANDUM
• TO: Parks and Recreation Co
FROM: Bruce Anderson, Parks
DATE: August 8, 2006 for the August 21 Patcltvc it b� ommission Meeting
SUBJECT: Carver Crossing Park Dedication p
INTRODUCTION
Copar Companies has formally submitted their final development proposal for property located
in southern Maplewood formerly known as the Schlomka property. The original application was
for 299 housing units which was possible through the E.A.W. down to the current proposal of
191 homes. The current plan would require three votes of support by the city council for
approval.
The Parks and Recreation Commission formally adopted a motion at their July 21 meeting to
support the $834,000 park dedication fee with $500,000 to be allocated to this development. A
second alternative proposal is outlined in the letter dated August 7, 2006 from Kurt Schneider of
Copar.
BACKGROUND
The Carver Crossing site is an assembly of land acquired by Copar from four different property
p Y
owners. The predominant surrounding land use includes Interstate highway 494 to the east and
Ramsey County surrounds it on the north, south and west. In addition the city currently owns 26
acres of open space (named Carver) to the north of Carver Avenue and west of Sterling Street.
The commission input in this proposed development centers around the park dedication options.
I have included a copy of the July 21 draft commission minutes that reflects the commission's
discussion and the formal motion made by the commission.
DISCUSSION
The cash park dedication fee that would be in effect for this project would be $3,060 per unit at
191 units it would be $584,460. Copar initially proposed that the city invest $250,000 of the
$584,460 park dedication fee monies to be directly allocated and spent within the proposed
Carver Crossing development. Copar would then match the city's commitment with an additional
$250,000 which would be $500,000 of proposed park improvements. This would leave $334,000
of P.A.C. monies that could be invested throughout the city of Maplewood. The Parks and
Recreation Commission unanimously adopted this proposal at your July 21 commission
meeting.
Copar has proposed a second option (outlined visually in Exhibit B) which would include the
following:
01. Dedication of a 2.9 -acre park and overlook area adjacent to the Ramsey County open
space to the south and west.
2. Dedication of a 2.2 -acre woodland park adjacent to Ramsey County open space to the
west and north.
3. Dedication of a 20 -foot trail corridor (.17 acre) adjacent to Ramsey County open space
to connect the overlook and woodland park locations. 0
4. Dedication of a 4.59 -acre trail corridor connecting to the Henry Lane turnabout.
The public dedication of the 10.56 acres of land area would be 14.6% of the property. The
developer would provide this land in lieu of the park dedication fees of $584,000.
Additionally Copar is proposing to dedicate a north/south regional trail corridor extending the
site from Carver Avenue to Ramsey County open space to the south in the amount of 4.25
acres, which would be approximately 20% of the site or just short of 15 acres. In addition, Copar
is proposing they would provide $250,000 to develop a public park and/or trailway system within
the dedicated 14.8 acres.
I have contacted Ramsey County Parks & Recreation to determine if they would be willing to
either manage the land and/or develop a regional trail system on the eastern edge of the
development. I have not received a formal response as of August 9.
After reviewing the two proposals and concepts, it is my recommendation that the city accept
the first option as approved at the July 21 meeting. My rationale for this is as follows:
1. The majority of the 14 acres of land will remain as open space whether the city receives
it in lieu of park dedication fees or not.
2. The land for the most part is unbuildable due to steep slopes and is not accessible.
3. The one major exception would be the 2.9 public scenic overlook area in the northwest
corner. I believe there is some public benefit to this parcel but the reality is, given the
location of the Copar site, I believe there would be very minimal usage by the public to
use this observation area.
4. 1 believe that the trail corridor issue on the eastern edge of the development should be a
city requirement or condition as part of the platting process with no P.A.C. credit
provided. Ramsey County has not indicated that they have interest in developing a
regional trail corridor, but I believe this would be in the best interest of the county that
this land be acquired for a potential future trail corridor. A case can certainly be made
that the development benefits greatly with a regional trail on the eastern edge.
5. Park dedication fees remain our number one source of revenue for park development.
The bottom line is that we would be giving up $585,000 for 14.8 acres of property, most
of which is unbuildable, and would benefit the county to a greater extent than the city.
The greatest benefit to acquisition of this land would be to the proposed project as
opposed to the city.
6. The city (if we were not able to deed the land to the county) would become responsible
for the maintenance and related operational issues of the 14.8 acres of land. This would
impose additional costs in the future regarding tree removal, slope management,
planting and liability.
In conclusion, it has been my position from the beginning (see enclosed memo dated May 4,
2006) that the city's residents are well served with parkland in southern Maplewood surrounding
this site. The parkland includes Ramsey County open space, Carver open space, Pleasantview
Park, and the active Carver Park in Woodbury to the east. I support that the development and
2
city would benefit from an expenditure of $500,000 of park monies which would meet the
recreational needs both passively and actively within the area.
• Lastly, I do not believe that this site has national significance as has been discussed. I concur
that the area is identified in some national guideline maps as part of the national open space
program, but I do not believe that there will ever be federal money available for acquisition and
the city would become liable and responsible both financially and legally for the acquisition of
the bluff areas.
I look forward to the commission's discussion and review of this issue on August 21.
RECOMMENDATION
Staff recommends that the commission review their position statement on July 21, 2006 about
park dedication fees at Carver Crossing and reconsider it in lieu of the alternate proposal by
Copar dated August 7, 2006.

TO: Ken Roberts, Plan
FROM: Bruce K. Anderson.IPbfkh lanffiRedreation Director
DATE: May 4, 2006
SUBJECT: Copar Development—Carver Crossing
I have had the opportunity to walk, drive and literally smell the land proposed to be developed by
Copar as Carver Crossing on at least six occasions. In addition, I had the opportunity to visit the
Schlomka property a number of years ago in the mid 1990s as part of the city's open space process.
First off, the property indeed offers spectacular views and a wide range of topography, vegetation and
abundant wildlife.
I would like to go on record with the following statements regarding the park position:
1. It is my understanding that the Copar development is focused on an over 55 year-old and/or
senior development as the primary focus. I further understand that it will be a combination of
housing from high-rise senior housing to single detached, townhouse and a variety of housing
structures.
2. The site is surrounded by Fish Creek Regional Park (130 acres), located both east and west of
1-494.
3. In addition to the Fish Creek Regional Park, the area is served with Carver Crossing (a 27 -
acre open space site) located at the corner of Carver Avenue and Sterling Street.
4. In addition to the city -owned open space, private open space is owned by a private, nonprofit
corporation for the ski jump property located directly east of Pleasantview Park.
5. The neighborhood is served by Pleasantview Park, a fully developed 14 -acre neighborhood
park at 1100 Marnie Street. Pleasantview Park includes play fields, basketball courts, picnic
grills, playground area, extensive trail system, and a portion of undeveloped and seating areas
that provide great vistas of downtown St. Paul.
6. The total estimated park development fee that the city would collect from this project (at
$3,000 per unit) is approximately $750,000 to $800,000.
7. The area is further served by Carver Lake Park, which is a former Campfire camp owned and
managed by Woodbury Parks and Recreation Department. Carver Lake Park boasts a public
swimming beach on Carver Lake and provides active recreation with an expansive trail
system, picnic facilities and trail system.
In conclusion, it is my recommendation that the city not pursue additional land or acreage in lieu of
park dedication fees. Given the fact that the proposed development is senior -oriented and is
surrounded by county open space, public-private land, Pleasantview Park, city -owned open space
and Carver Lake Park owned by the city of Woodbury, additional public park land is not needed.

Re: Carver Crossing of Maplewood Revised Development Plan Submittal
Dear Mayor Longrie, Council Members, and Members of the Planning Commission,
CoPar Development is pleased to present the revised Calver Crossing of Maplewood
development plans for your consideration. Our development team has worked diligently to
revise the development proposal from its original 386 home city authorized EAW concept to a
191 home proposal that is consistent with the R-1 Comprehensive Plan Land Use designation of
the city. We feel strongly that the revised proposal is reasonably exercising our rights to develop
while being sensitive to the diverse site conditions and considerate of the public input gathered
throughout the past 19 months.
We respectfully request that the City of Maplewood review our revised proposal and approve the
following actions as they relate to the development plans:
1. Conditional Use Permit / PUD approval
2. Preliminary Plat
Outlined below are a number of development plan highlights intended to assist you in answering
questions that may arise as you review our plans.
Site Background:
The Carver Crossing property is an assembly of land acquired by CoPar from four different
previous owners. The predominant surrounding land uses include Interstate Highway 494 and
vast amounts (100+ acres) of Ramsey County open space. Surrounding land uses also include
the 1986 Carver Heights development (Dorland Road); some isolated homes on Carver Avenue;
and approximately 26 acres of city owned "Grandview" land acquired by the city in 1995/1996
which was changed from a Land Use Plan designation of R-1 (single dwellings) to OS (open
space) upon acquisition.
Historical land use activities on the property include four residential homes, numerous out
buildings, limited farm related activities, and excavation, boat and material storage. CoPar has
carried out building demolition and site clean-up activities to prepare the property for
development. Substantial numbers of tires, debris, outdoor storage and discarded materials have

been removed from the property. In the process of site investigation and clean-up a small •
amount of soil contamination was identified and is depicted in Figure 1 from Summit
Envirosolutions, Inc. Approximately 2,000 yards of contaminated soils are being removed from -
these areas in accordance with the MPCA Voluntary Investigation and Clean-up (VIC) and
Brownfield's Programs. We are proud of our efforts to correct the blighted conditions that
existed on the property.
The most recent site related activities and background include the conclusion of the city managed
Environmental Assessment Worksheet and findings of a negative declaration concerning the
need for an Environmental Impact Statement. Among the many valuable pieces of information
gleaned from the EAW site research and findings it has been determined that the entire site can
be reasonably developed without a potential for significant environmental effects.
City Land Use Plan:
The Maplewood Comprehensive Plan identifies the entire site as a Single Dwelling (R-1)
development area eligible for development at a density of 4.1 homes per acre. Maintaining clear
consistency with the single dwelling development directive identified in the Comprehensive Plan
is the basis for the plan revisions that have occurred since the conclusion of the EAW process.
Community feedback and Planning Commission recommendations made it clear that a PUD is
appropriate, but an alternative multiple dwelling proposal is not acceptable nor should the
Comprehensive Land Use Plan be changed. The revised proposal has removed all multiple
dwelling and attached townhome housing options from consideration and the development
contract with the previously identified builder has expired.
The EAW has accounted for the uniqueness of the site and the plan revision process has resulted •
in a development proposal that is exercising the minimum development rights afforded to the
property. The site is not identified by the 2002 Maplewood Comprehensive Plan as a Residential
Estate 30,000 or 40,000 sq. ft. (re -30, re -40) development area; Open Space (OS) preservation
area; or Park (P) development location. The proposed density is consistent with the minimum
density allowed in the Mississippi River Corridor Critical Area (Ref city ordinance Sec. 12-250.
Effect on Density) and is clustering home sites in a manner that emphasizes open space
accessibility to all current and future residents. The amount of open space in this plan has
actually increased from that the multiple family and townhome plans depicted in the EAW. The
attached Comprehensive Plan Land Use Maps were obtained from the official city web site and
plainly identify the development designations of the site.
PUD Development Overview:
The development site is 72.3 acres in size with a development density that has been reduced
from 4.1 to 2.64 homes per acre. The development plan is proposed as a Planned Unit
Development (PUD) resulting in the designation of 27.87 acres of privately owned woodland,
wetland and upland open space. The 191 proposed lots average approximately 7,600 sq. ft. and
each will support a 2,400 sq. ft. or larger building pad site. The lot designs and layout will result
in a full range of single dwelling size and elevation alternatives. Homes will be built by a select
and qualified builder or pool of builders that has yet to be determined.
-2-
My recommendation is that the city pursue park dedication fees. The developer is further requested to
meet the following conditions:
1. A tot lot would be constructed for grandchildren and/or visiting children that would be a public
tot lot to serve the surrounding property owners.
2. The sidewalk trail system be public and made available to the public.
3. Two areas be set aside as vista viewing points to be constructed and developed at the city's
expense at a future date.
4. Trail access be afforded to Fish Creek Regional Park for the residents within the proposed
development.
In addition, it will be my recommendation to the Parks and Recreation Commission that a minimum of
one-third of the park dedication fees collected be allocated south of Mailand Road in southern
Maplewood.
Should you have any questions regarding this request or position statement, feel free to contact me
directly at ext. 2102.

• The incorporation of PUD development techniques has enhanced the development proposal by
allowing 38.5% of the site to remain open with a diverse and mixed terrain upland, woodland,
and wetland presence that could not otherwise be attained. Open spaces and rain garden or other
site features have been integrated into the site plan and are directly adjacent to over 97% of the
homes. The PUD will also allow consistent and enhanced natural feature protection through the
managed open space ownership of the homeowners association. The open spaces within this
development accompanied by the large expanse of Ramsey County open space and sizable city
open space to the north will continue to allow the natural areas in the area to be a dominating
feature of south Maplewood. The open space plan is identified on sheet C-8 of the development
plans and comprises approximately 3.03 acres of woodland, 17.64 acres of upland/grassland, and
7.2 acres of wetland.
Stormwater Management:
The stormwater management plan is highlighted on the attached Exhibit A and can be reviewed
in detail on sheet C-6 of the development plan submittal. A total of 6 Permanent Dual Purpose
Basins (PDPB's) and 7 rain gardens have been designed for the site. The total infiltration
volume proposed has increased from the plans presented in the EAW to 106,150 Cubic Feet.
The stormwater management plan provides infiltration for rainfall events of at least 2.5", and
vastly exceeds the Mississippi River Corridor Critical Area requirements, the Watershed District,
and the City standards for water quality treatment. Stormwater management as it relates to Fish
Creek and the slopes and natural features of the site have been a strong factor in the design of
this development plan and set a precedent for other such developments to attain.
• The stormwater plan and PDPB design elements in our proposal have not been considered solely
for their function as effective stormwater control. The design specifications also include detailed
native seeding specifications to enhance the form and appeal of the area. Specified in detail
within the landscape plan are native seeding specifications, application rates, and cover
requirements that will perform the dual purpose of stormwater treatment and landscape
enhancement.
Estimated earthwork has increased from 217,000 yards to 290,000 yards. The additional amount
of excavation can be attributed to the increased number of water treatment basins and is therefore
the result of an increase to the protection of Fish Creek through additional water quality
treatment. As discussed in the stormwater plan summary, water quality treatment has been a
precedent setting element to the design of this development and has been a primary consideration
in the proposal. Additional earthwork can also be attributed to increased berm and landscape
related efforts.
As was concluded in the EAW, the amount of earthwork associated with the project is not
unusual when considering the size of the property. It is reasonable to make the same conclusion
with this revised earthwork and stormwater plan. To put the level of earthwork into perspective,
290,000 yards is equivalent to an average of +/- 3.3 ft. depth of excavation taken over the limits
of the site improvements. The increase of 73,000 yards is equivalent to +/- 9 inches of additional
cut from the depth of excavation in the EAW.

Park Dedication: •
The park dedication fee in effect during the presentation of the original development concept to - the City Council and during the subsequent plan and EAW preparation period was doubled by
the city on February 13, 2006. The current park dedication fee for a new single family home is
$3,060. In accordance with this recent fee adjustment, the park fee obligations of the revised
plan are estimated as $584,460. Though the amount of the fee was equivalent to $292,230 prior
to this change, CoPar is prepared to pay the new park dedication fee as has been advised by the
city parks department staff and parks commission.
As the development planning process has evolved interested parties have voiced concerns about
the lack of public park and trail improvement in the area. Although this site is not identified by
city planning documents as Park or Open Space, CoPar has devised two options to help address
issue:
Cash Dedication Option:
CoPar proposes the city investment of $250,000 of the $584,460 city park dedication fee directly
into the 191 home development for the purpose of public trail and public park/overlook
improvements. CoPar will match this direct investment of park fees with an additional dollar for
dollar or like -kind park/trail improvement valued up to $250,000. This dollar for dollar match is
conditioned on maintaining the continuity of the current 2.64 single family home per acre
development plan. Implementation of this proposal can occur upon plan approval and would
result in a positive park improvement impact to the city of $834,460 with $500,000 invested
directly into south Maplewood. •
Park enhancement opportunities we envision within the development include both active and
passive recreation activities. An extensive sidewalk/trail plan incorporating the upland,
woodland and wetland features of the site, nature walk interpretive signage, Fish Creek and other
prominent site vista stations, birding, nesting, and other related habitat improvements,
observation and bird feeding stations, and even raptor nesting platforms are a few of the
enhancements we envision could be of great benefit to the public and the environment.
Land Dedication Option:
Understanding that there has been a desire by interested parties to purchase portions of the
property or otherwise pursue pubic ownership we have also prepared a park land dedication
proposal that could be implemented without objection. Illustrated on Exhibit B is a park land
dedication proposal as follows:
I. Dedication of a 2.98 acre park and overlook area adjacent to Ramsey County open space
to the south and west;
2. Dedication of a 2.82 acre woodland park area adjacent to Ramsey county open space to
the west and north;
3. Dedication of a 20 ft trail corridor (.17 acre) adjacent to Ramsey County open space to
connect the overlook and woodland park locations; and
• 4. Dedication of a 4.59 trail corridor connecting to the Henry Lane roundabout.
The public dedication of the combined 10.56 acres of land area (14.6% of the property)
described above would be in lieu of the $584,460 fee. City acceptance of these site areas would
provide a tremendous park development opportunity to the city. The site density would be
reduced in these areas with the removal of four (4) very desirable home sites; however, we feel
the removal of these homes would be necessary to allow improved park development and access.
The incorporation of a public road plan may also be required with this option.
In addition to the above land dedication CoPar is also willing to dedicate a north/south regional
trail corridor through the site extending from Carver Avenue to the Ramsey County land area to
the south. This additional land area is approximately 4.25 acres and when combined with the
10.56 acre dedication proposal above equates to a park land dedication of 20% of the property;
double the land area dedication that would customarily be required to satisfy city ordinance.
Interested parties have expressed a desire for regional trail connections through this site and we
believe they could be accommodated with this additional land area proposal.
CoPar will not be accepting of alternative park land dedication or acreage configurations in lieu
of the park dedication fee but is willing to accommodate the above proposal should the city wish
to accept park land in lieu of fees. No part of the development property is identified by the city
Land Use Plan as park or open space and Copar feels no obligation to involuntarily dedicate park
land within the site.
Recognizing the cities budgetary constraints in immediately improving the 14.8 acres of public
• park land in this proposal, CoPar would include the equivalent of $250,000 in resources to
enhance and develop a public park and trailway plan for these city park areas. These additional
resources would be contributed conditioned on the continued continuity of the current
development plan and in a manner consistent with the phasing of the development.
LandscaRe..
There are 1,111 significant trees on the property. Significant trees are defined by city ordinance
and are individually identified on the tree survey contained within the development set as sheet
C-7. The revised layout has resulted in the preservation of 646 significant trees and resulted in a
reduced tree impact when compared to the development plan in the EAW. The reduced tree
impact was attained through the use of specific site design efforts and the reduction of density
from 197 to 191 homes.
A total of 723 trees (10/per acre) are required by ordinance to be maintained and or placed on the
site. In conjunction with the preservation of the 646 significant trees, city ordinance would
require the planting of an additional 77 trees. The landscape plan is exceeding the ordinance
requirement and proposing to plant 546 mixed variety trees. The landscape plan has been
designed by a registered Landscape Architect and is incorporating not only diverse tree varieties
but also pond seed mixes focused on native and emergent wetland fringe and native prairie
grasses.
Wetlands: is
Wetland impacts remain unchanged from the EAW proposal. The site contains 319,076 sq. ft. of
wetland of which only 8,879 sq. ft. or 2.78% will be impacted. In accordance with the State of
Minnesota Wetland Conservation Act the impacted wetland is being replaced with a slightly
larger new wetland accompanied by an additional 146,662 sq. ft. of qualifying public value
credit improvements. The wetland replacement plan vastly exceeds the criteria established by
the Wetland Conservation Act and is depicted along with the stormwater management plan on
sheet C-6 of the development proposal. The Watershed District has approved of the wetland
sequencing and replacement plan.
The development proposal has also accounted for city and watershed district wetland
classification and building setback regulations. The average building setbacks surrounding all
wetlands exceed 50 ft. and the 25 ft. no disturb area and added 10 ft. structural buffer setbacks
have been met as depicted on the Site Plan on sheet C-3 of the development proposal.
Noise:
As the EAW identified, the development site is impacted by noise levels generated by Interstate
494. As the plan revisions have taken shape the outdoor spaces have been actively planned as
they relate to these noise impacts. As depicted on Exhibit C, the highest noise measurement
area (70 dBA) is no longer impacting any homes and the daytime noise area (65 dBA) which
previously impacted 137 homes is now touching 28 home sites. Homes have also been
strategically located to further limit and shield noise exposure to the rear yard recreation areas.
The site layout and planning process has reasonably balanced the development potential of the
property with the noise impacts that have been forced upon it. •
As advised by city staff, site grading, berming and landscape have been adjusted to help mitigate
noise impacts. The cross section depicted on Exhibit D & E demonstrates the substantial grade
and topography differences and the grading and landscape enhancements that also help mitigate
these noise impacts. The north end of the site depicted in Section "E" is 17 feet lower than the
grade of I694; the mid section of the site depicted in Section "D" is 24 feet lower than the grade
of I694; the proposed roundabout area depicted in Section "C" is 18 ft. lower than the grade of
I694; the southern portions of the site are buffered by increased setbacks, topography changes,
ponding, and landscape and depicted in Section `B" as 6 Meet lower than the grade of I694; and
Section "A" is 26 feet higher than the grade of I694. Although a limited number of homes
remain in the daytime noise area the site design is taking practical and reasonable steps to
accommodate the impact, including the designation of approximately 6 acres of the site within
the daytime noise area as open space.
Public Utilities & Roads:
Sewer and water utilities are available to the entire development site from both Carver Avenue
and Heights Avenue and are proposed to be extended throughout the site as public infrastructure.
The plan no longer requires a lift station as it has been determined that the revised design and
density can be fully accommodated with existing available connections. Removal of the lift
-6- 0
• station is a significant long term maintenance and cost savings to the city, We are pleased with
the added efficiencies of the utility design.
The extension of utility connection points east under Interstate 494 has been affiliated with this
project but is not being requested or required by CoPar. As an alternative, future jacking pit and
utility extension under Interstate 494 could potentially be accommodated from the East side of
the interstate as the benefiting property owners request it. We believe the removal of the lift
station allows the location of any future "jacking pit" or I494 boring activity to be accomplished
in a less exact fashion that can be more easily accommodated from either side of the highway.
We'd suggest making that investment when the residents and property owners to the east request
it.
As proposed, all roads within the development that are providing direct driveway access to
homeowners are private. The road identified as Henry Lane continues to be public road that
intersects with Carver Avenue. The intersection with Carver Avenue, however, has been
adjusted an additional 112 ft. west to avoid aligning with homes on the north side of Carver
Avenue. Henry Lane is also slightly shorter in length than the existing Henry Lane and is
terminated through the use of a roundabout.
It has been suggested that the long term maintenance and care of the proposed private roadways
may be cause for concern and that public roadway should be considered throughout the project.
We have evaluated the potential of accommodating public roadways and can construct the road
plan to a public standard within the current 50 ft. wide street outlot(s) by adding an additional
two feet of road width. At the direction of the city we are willing to assume the additional
• development cost, dedicate the appropriate right-of-way, and construct public roads throughout
the development should the Planning Commission and City Council prefer public roads.
Traffic:
Traffic from Maplewood and neighboring communities is a concern throughout the region and is
caused by both existing residential developments as well as new. Carver Crossing will increase
traffic in the area in a manner that has been analyzed and accepted in the EAW. The revised
proposal has decreased in density and lessened the traffic impact. The revised proposal has also
adjusted the alignment of the Henry Lane intersection an additional 112 feet west to reasonably
accommodate headlight glare concerns expressed by a neighboring property owner to the north.
CoPar will cooperate with the construction of Henry Lane turn lanes and Carver/McKnight
intersection improvements. Although once planned by the city, a full road connection is not
proposed to the temporary cul-de-sac in the Dorland Rd. /Heights Ave. neighborhood to the
west. An oversized emergency outlet "trail" to this temporary cul-de-sac continues to be
identified and will be designed with appropriate barriers as required by the city. The barriers
will prevent everyday use of the trail as a vehicular access and will allow emergency vehicle
through traffic as needed.
0 -7-
Fish Creek: •
Fish Creek is a positive amenity adjacent to this project and is being protected to a great extent
through the blighted site clean-up, soils contamination removal, and stormwater controls that are
a part of the development. The plan revision has emphasized the enhanced protection of the
creek by dedicating additional open space along the full north and south sides of the creek as it
runs through the project area. Plan revisions have also been able to preserve added trees along
the creek, incorporate an expanded conservation easement area, and incorporate permanent
erosion control and grading restoration activities to stop the degradation of the area.
Three isolated bluff locations exist along the south side of Fish creek and are depicted on the
attached Exhibit F. Identified are the 30 ft. shoreland bluff setbacks accompanied by building
pad options that exist in satisfaction of the shoreland ordinance requirements. As can be seen in
Exhibit G, the building site setbacks from the creek range from 91 to 300+ feet. The minimum
Fish Creek setback of 50 ft. has been doubled in all but one location. Restoration activities in
these areas are including the use of retaining wall work, plantings, and erosion control measures.
Existing conditions include several "ravine" and washout locations that will be permanently
corrected and protected with the implementation of the grading and stormwater controls of this
development.
The Watershed District has managed historical erosion problems associated with Fish Creek
through extensive structural improvements to the creek from this site west all the way to the
Mississippi River. Alterations to the creek have included the installation of an underground
stormwater pipe that ranges from 36 to 48 inches in size and is intended to channel and re-route
water flow. The water entrance to this structure is located at the spillway and small pool area •
depicted on our plans and is being moved further east to I494 with additional Watershed District
construction and pipe installation activities scheduled to commence work in the coming week(s).
To assist the Watershed District in its efforts to maintain the Creek we have formalized two
permanent access points from the north and south to these areas of Ramsey County property.
There is no question Fish Creek has been subject to washouts and erosion. If developments
upstream from Carver Crossing implemented the same stormwater management techniques as
our development we feel confident that long tern solutions to the erosion and quality of the
creek would be fully resolved.
Mississippi River Critical Area Corridor:
The Mississippi River Corridor Critical Area (MRCCA/MRCAC) area as defined by State
Statute is depicted in Exhibit H. Regulations pertaining to this area of the site are being met
with the revised proposal in the same manner they were met within the EAW. The development
plans have fully considered the Environmental Protection and Critical Area ordinance
requirements of the city. The proposed development has the potential of greatly increasing
public access to and along Fish Creek; is being designed and will be constructed and maintained
to the maximum extent practical as it relates to erosion, alterations, and slopes; is removing site
contamination and pollution, is not impacting the views of protected waters, and is vastly
exceeding stormwater ponding and phosphorous removal requirements outlined by ordinance.
-8- •
• The plan no longer requires critical area plan amendments from the Mn/DNR as the
Comprehensive Plan is no longer being amended.
The potential for MRCAC designated areas within the site to have qualifying blufflines has been
fully evaluated. Though there are clearly slopes of 18% or greater within the site, the additional
criteria necessary to establish a bluffline as defined in city ordinance are not met. Qualifying
areas require direct drainage to protected water (Fish Creek); must be greater than 200 feet in
length (top to bottom) or greater than 500 feet in width (side to side). Depicted on Exhibit I is a
summarized slope analysis depicting dimension lines that demonstrate the lack of slope length or
direct drainage.
Demographic & Fiscal Impact:
The 191 homes proposed in Carver Crossing of Maplewood will be open to all qualified buyers
and maintained as minimum maintenance single family homes. The Maplewood Comprehensive
Plan estimates 2.9 people per unit live in a single dwelling and 2.2 people per unit live in a
townhome. Using these household estimates as an approximate range, the projected population
of Carver Crossing at full development should be within 420 to 554 people. Due to the style of
housing offered the demographics are expected to comprise of downsizing baby boomers, empty
nesters and professionals.
A conservative estimated gross retail sales mean of the homes in Carver Crossing is $378,000.
The League of Minnesota Cities tax calculator estimates annual Carver Crossing tax revenue at
$925,600. The city share of this yearly tax revenue is estimated at $261,000; the annual school
• and county share of this tax revenue is estimated at $664,000.
Conclusion:
We hope you agree that the Carver Crossing of Maplewood development proposal represents a
practical and reasonable implementation of the cities R-1 single dwelling land use development
plan for the property. We feel that the level of work that has been incorporated in the concepts,
EAW, and plan development and revision process have resulted in a very high quality proposal
for your consideration. Without undue delay we hope to receive your approval and construct this
development in a manner that enhances the open spaces, recreational opportunities, and
awareness of the desirable neighborhood elements available to people in south Maplewood.
Please do not hesitate to contact CoPar Development with any questions as you review this
proposal. We look forward to meeting with yourselves and the Planning Commission in
September.
Sincerely,

The Comprehensive Parks and Open Space Plan was completed in December 1999. As part of the
development of the planning process, the commission and city staff depended a great deal on input
from our stakeholders.
It would be appropriate for the commission to develop another survey for our stakeholders to address.
We should forward a copy of the comprehensive plan and solicit input and/or changes based on their
involvement as stakeholders.
Stakeholders would include athletic associations, community service groups, school districts, park
users, private businesses, corporations and public policy groups such as the planning commission
and city council.

Stakeholder
Involvement in System
Planning and
Assessment of Need
Identifying stakeholders, getting them
involved in the planning process, and
building long-term relationships with
them are critical steps in planning a
parks, open space, and trail system that
will meet community needs today and
tomorrow.
The term stakeholder is purposefully
used here to underscore the importance
of showing greater sensitivity by the city
to the views and opinions of various
users and then providing a system of
parks and trails that respond to those
opinions. In this way, the city is
planning with people instead of for
them.
This approach to planning was used for this study.
As the system planning model illustrates, identifying stakeholders,
getting them involved in the planning process, and building long-term
relationships with them are critical steps in planning a parks, open
space, and trail system that will meet community needs today and
tomorrow. The public process allows the city to gain a better
understanding of the community's perceptions and value system,
which in turn allows for the development of a plan that responds to
those sensibilities.
Defining Stakeholders
The term stakeholder refers to anyone that has a vested interest in
some aspect of the park, open space, and trail system within the
community. It is meant to be an all-encompassing term that focuses
on identifying and involving target publics (i.e., the common citizen,
various "customers", patrons, user groups, non-users, and so forth) in
the planning process.
The term stakeholder is purposefully used here to underscore the
importance of showing greater sensitivity by the city to the views and
opinions of various users and then providing a system of parks and
trails that respond to those opinions in a rational and responsible way
that maximizes the derived benefits to the community. In this way,
the city is planning with people instead of for them.
Linear Versus Strategic Stakeholder Involvement
Model
A key factor in embracing stakeholder input into the planning process
is following a model whereby ongoing public input is fundamental to
the decision process. The following figures highlight the difference
between a linear, or traditional, involvement model and a strategic
model to underscore the importance of stakeholder involvement in
system planning.

SUBJECT: Monthly Update—July 2006
21 Parke and Recreation Commission Meeting
The following items are provided to the Interim City Manager and Parks and Recreation Commission
to provide an overview of our day-to-day operations. The items are informational and not intended for
formal City Council or Parks and Recreation Commission action.
1. 2006 Readers' Choice Awards
The Maplewood Community Center was recognized by the Lillie Newspaper and more importantly,
the residents of Maplewood, as the best fitness center and best community center. The article in
the Lillie News states that "the Maplewood Community Center is pleased to receive the '2006
Readers' Choice Award' for the 'Best Fitness Center' for five years in a row." The community
center focuses on the community's fitness needs including free fitness classes ranging from
spinning to yoga. In addition to the spectacular community center, we pride ourselves in quality
programs, exceptional service and state-of-the-art fitness equipment. The community center is
experiencing the 12th consecutive year of increased revenues.
• 2. Hill-Murray/Highway 5/Century Avenue/MnDOT Property
I have been actively involved in working with the representatives of Hill -Murray High School, cities
of Oakdale and North St. Paul, and other Maplewood residents to determine the feasibility of
developing a portion of the Highway 5 and Highway 120 property with athletic facilities. Our group
has met on five occasions and will be preparing a report for city council consideration in October.
The group is currently focusing on communitywide usage needs as well as the feasibility of
establishing soccer fields in and around the necessary wetland -delineated areas. I have continued
to represent the city's position that we are not interested in providing financial support for athletic
fields, but have indicated that if nature center trails and/or connections between the Priory open
space site and open space property to the east were to be a part of the plan, we would consider
financial support.
3. MCC Pool Shutdown
The Maplewood Community Center will be closed beginning August 20. The pool will be closed for
an extended period of time this year due to the painting project. The schedule at this point is to
have the painters mobilize and set up August 21-24, the pool will be sandblasted and blown down
on August 25 -September 7, painting will occur from September 8-19, with cleanup and
demobilization from September 20-22. The remaining deck cleaning and maintenance will be the
week of September 23-29, with the pool scheduled for a pool opening party on September 29. In
addition to the pool painting, the hardwood floors will be redone in the racquetball courts and
aerobics floor, as well as painting of the women's restroom. This is always a period of time when
is everyone chips in to do a major cleaning of the entire community center.
4. National Night Out
National Night Out was held on Tuesday, August 1. The National Night Out program was a joint •
effort between our department and police and fire departments. This year's National Night Out
program was expanded to 83 parties. This is an increase of 17 or 20% over last year.
Unfortunately rain, which we needed so desperately, came into play. In spite of the rain, the
parties were all held as scheduled but numbers were down precipitously—no pun intended. One
of the new programs that we added this year was food donation. Due to the generous donation of
residents, we provided over 1,000 pounds of food to Second Harvest. My hat's off to everyone
involved in this program. I remain convinced that this is our first line of community defense and a
very important community-based program for all Maplewood residents.
5. Silver Lake
I have been meeting with a number of representatives ranging from park users to property owners
to the local watershed district regarding the water quality at Silver Lake. I have included a copy of
one of the working plans regarding Silver Lake. The city is the major landowner on Silver Lake
with Joy Park encompassing 60 acres. Joy Park master plan has been approved by the city
council and slated for improvements in 2007 and 2008. Staff will be preparing a resolution of
support for city council consideration regarding grant applications both through the watershed
district and the local property owners in the coming weeks.
6. Communitas Classical Academy
During the past three months, negotiations have been taking place between Communitas
Classical Academy (a private school) and city staff regarding usage at the Maplewood Community
Center. It appears that we will be entering into a formal lease agreement with Communitas •
Classical Academy for use of the craft room and related gym and pool facilities for an eight- to ten-
month period. Details are still being finalized, but it appears that they will be mainly utilizing the
craft room at a rate of $1,500 per month. All students will also be required to become members of
the Maplewood Community Center. At this time the school has ten middle school students
registered and they project to begin school in mid September. This will be a new lease agreement
for the MCC and we look forward to a positive and long-term relationship.
7. Guest Lecturer
I frequently serve as a guest lecturer at the University of Minnesota in the parks and recreation
curriculum. My next opportunity to present will be on October 24 to speak on future trends within
the parks and recreation field. Most of the engagements are in the evening and I enjoy the
opportunity to interchange with both undergraduate and graduate students regarding my
experiences over the past 38 years. The speaking engagement on October 24 will be a first for me
as I'll be bringing our oldest daughter along who is a graduate of the University of Wisconsin in
parks and recreation administration and serves as a recreation program supervisor in the city of
Shoreview.

Lake during the May 12 through
October 31 period was 17,400 hours.
The total number of hours of uses was
divided by the area of the lake to
determine the lake's intensity of use.
Silver Lake had a total recreational use
of 194 hours per acre.
The lake's intensive use is due primarily
to the two parks located adjacent to the
lake. A park on the south shore is owned
by the City of North St. Paul and
includes a public swimming beach, a
fishing pier, and an extensive picnic
area. Joy Park on the north end is owned
by Ramsey County and contains three
picnic areas and a public boat launch,
which also provides winter access.
The primary recreational uses of Silver
Lake are swimming and fishing. A 1978
Minnesota Department of Natural
Resources (DNR) recreational use
survey estimated the lake supports
fishing at the rate of 76 person -hours per
acre, twice the regional average. The
installation of a boat access in 1984
significantly increased fishing pressure.
Other recreational uses include

5.1.2 Water Quality Management Plan
The current conditions of Silver Lake meet the VBWD guidelines for an Excellent -ranked water
body. Using the categories of the 1995 VBWD Water. Management Plan, Silver Lake was classified
asaLevel I (fully -supporting) water body. Thedraft August 2000 report, Tri -Lakes (Lakes
DeMontreville, Olson and Jane), Long, Echo, Mud (Acorn) and Silver Lakes, Watershed and Lake
Management Plan, Volume I; Lake and Watershed Conditions, Water Quality Analysis, Improvement
Options and Recommendation (Tri -Lakes Watershed and Lake Management Plan), found that S1Iver
Lake generally met the VBWD water quality goalsfor Level I lakes, except the mean summer total
phosphorus concentrati ons someti mes exceeded the goal of 30 µg/l. Usi ng stati sti cad anal ysi s on the
hi stori c Secchi transparency depth data, the cl arity of Si I ver Lake's water i s i mprovi ng at a rate of
0.072 meters per year (about 2.8 inches per year). The VBWD will manage Silver Lake asaHigh
Pri ority water body. Because Si I ver Lake has a publ i c access, it i s the most i ntensely used V BWD
. lake, and it isan intensely used Iakein the regi on, the VBWD will giveit ahigher priority for
i mpl ementi ng water quad i ty protecti on and/or i mprovement proj ects than other I akes wi th I ess
intensive use and/or lakes without public accesses.
The V B WD water quality chemistry gui deli nes f or Excel I ent water quality ranked water bodies,
including Silver Lake, weasfolIows:
• M i ni mum summer Secchi disc depth (a measurement of water transparency) of at l east
1.1 meters (3.5 feet)

Of equal importance are guidelines related to aesthetic enjoyment and wildlife habitat to •
maintain/improve desired use of the water body. See Table 5 in Appendix B-4.2 for a listing of
habitat indicators.
5.1.2.1 Water Quality Implementation Plan
Specific water quality implementation tasks for Silver Lake include the following:
1. The VBWD will monitor the water quality of Silver Lake and perform the actions discussed
in Section 4.2 — Water Quality for High Priority water bodies. Since Ramsey County
conducts an annual water quality monitoring program for Silver Lake, VBWD has no plans to
duplicate water quality sampling programs on the lake. The VBWD may conduct more
intense monitoring on the lake (see later bullet point). VBWD will request that a copy of all
water quality monitoring reports conducted by others for Silver Lake be sent to VBWD.
The VBWD will evaluate the average summertime Secchi disc transparency depth measured
at the lake and compare it to the VBWD Silver Lake action trigger. For Silver Lake, the
action trigger is currently 2.3 meters (7.5 feet), but it will be re -calculated by the VBWD
after each sampling year. Depending on any trends in the lake's water quality, the VBWD
will take various actions based on the guidelines described in Table 4.2-5. Currently, there is
a significant improving Secchi disc transparency depth trend at Silver Lake. This means that
if the Secchi disc transparency depth is more than 2.3 meters, the VBWD will take no further
action and will continue its monitoring plan. However, if Silver Lake's Secchi disc •
transparency depth is less than 2.3 meters, the VBWD will perform Survey Level plus
Supplemental Water Quality Monitoring the following year
2. The VBWD will evaluate and implement the appropriate recommendations listed in the Tri -
Lakes Watershed and Lake Management Plan. Through the Tri -Lakes Watershed and Lake
Management Plan, the VBWD evaluated a number of water quality management practices to
estimate their cumulative effect on the water quality of Silver Lake. The management
practices evaluated in the report include: wet detention, prefabricated stormwater treatment
units, a stormwater alum treatment plant, in -lake alum treatment, in -lake herbicide
treatments, and general best management practices. The VBWD Managers recognize that new
technology and/or methods may become available for improving water quality, including
managing exotic/invasive aquatic plants, and will investigate these new technologies/methods
as they consider implementing water quality improvement projects. The Tri -Lakes Watershed
and Lake Management Plan found that implementing some of these management practices at
Silver Lake would likely improve the lake's water quality and ensure Silver Lake's water
quality meets the VBWD goals on a more consistent basis. For Silver Lake, the VBWD will
consider implementing the following:
a. More intense monitoring will be conducted to better estimate how much phosphorus
is entering the lake, and ultimately, determine the feasibility and cost-effectiveness of •
improvement options listed in the Tri -Lakes Watershed and Lake Management Plan.

b. Aluminum sulfate (alum) may beareally applied to Silver Lake to provide along -
term control of the phosphorus release of lake sedimenta This i n -I ake treatment could
be effective for approximately ten years, depending upon how well the watershed
nutrient sources have been reduced. When al um 1 s app) i ed to shad l ow I akes, the

control the biological comment. The Tri -Lakes Watershed and Lake Management
Plan addressed the impact of curl yleat pondweed (one of the biologi csi components)
on i nternal phosphorus I oadi ng, but not other biol ogi cal components, such as hi gh
popul ati ons of bottom-feedi ng (benthi vorous) f i sh or hi gh popul ati ons of stunted

manipulating the bi ol ogi Cal food chain (i.e. biomani pul ation) in Silver Lake asa

S] I ver Lake had poorer water quad ity prior to 1985. The DNR bel i eves the change in water quality
was associated with a change in the I ake's f i sh popul ati on. Prior to 1978, the I ake was subject to •
seasonally l ow oxygen I eve! s resul ti ng in wi nterki I I s Frequent wi nterki I Is prevented the
establishment of a gamef i sh population and enabled a large black bul I head popul ati onto f I ouri sh in
the I aka Si nce 1978, however, wi nter aerati on has enalbl ed a gamef i sh popul ati on to become
establ i shed i n the I ake. The gamel' i sh popul ati on control s the bottom -f eedi ng bul i heads and panf i sh,
both of which contri bute to degraded water qua] ity.
The establ i shment of a gamef i sh popul ati on has caused a dramati c decl i ne i n the bul I head popul ati on
in the lake, due to the effectsof competition between f i sh speci es. InitidIy, the decl i ne was i n the
form of an el ] mi nati on of smal I er bul I heads I n 1985, the death of I arge numbers of older bul I heads
resul ted i n a dramati c ded i ne i n the bul I head popul ati on. The D N R reports that trapnet catches of
bul I heads ded i ned f rom 130 i n 1980, to 19.5 i n 1985, to 1.5 i n 1990 to 0.2 i n 2000.
Pri or to 1985, the I arge numbers of bul I heads i n the I ake added nutri ents to the water by sti rri ng up
bottom sediments and excreting nutrients into the water. The reduction in nutrients in Si I ver Lake
duri ng 1985 and i n subsequent years appears to be I argel y due to the deal i ne i n the bul I head
popul ati on. Drought conditi ons duri ng 1987 through 1989 reduced nutri ent I oadi ng to the I ake, whi ch
i mproved its water qud Ity. The water qud ity i mprovement that occurred duri ng the late 1980s
appears to be a combi nati on of a change i n the f i sh popul ati on and d i mati c condi ti ons.
The water quad ity changes noted as a result of the change in f sh population within the lake are •
expected to Conti nue wi thout i nterrupti on. Ramsey County operated a portabi a pump and aerati on
baff I e system f rom 1977 through 1985 to prevent wi nterki I I i n the I ake. A permanent pump and

The DNR has determined afisheries-usedassificationfor Silver Lake in with the •
accordance h e DNR s
An Ecological Classification of Minnesota Lakes with Associated Fish Corrmunities(1992). Silver
Lake is classified as a Class 401 ake. A Class 401 ake i s a northern pi ke-panf i sh I ake. This I eked ass
i ndi cates the I ake should maintain a water transparency as measured by Secchi disc of 1.5 meters (4.8
feet) or greater. Poorer water transparencies will result in I ess than ideal water quality conditi ons for
the 1 ake's f i shery. Whi I e the average summer Secchi disc transparency depths of Silver Lake have
been greater than 1.5 meters since 1985, the minimum summer Secchi disc depths were less than 1.5
meters f rom 1985-1989,1991, and 2001. The data i ndi tate water quality improvement i s needed to
support the lake's fisheries -use classification. Figure 5.1-3 and Appendix A-5.1 show the average
and mi ni mum summer Secchi di sc transparency depths for Si I ver L ake.
Fish consumption advisories have been issued for fish caught from Si l ver Lake. Pregnant women and
children underage 15 should limit their meals of fish from Si l ver L ake to one meal per week. The
general population should limit its consumption of wal I eyes f rom Si i ver L ake to one meal per week.
The advisories are for mercury.
Additional Silver Lakefishery information is included in Appendix B-5.1.
5.1.2.4.2 Macrophytes (Large Aquatic Plants)
Macrophyte surveys were conducted on June 24, 1999 and August 26, 1999 at Silver Lake. Appendix •
C-5.1 i nd udes i nformati on f rom the 1999 macrophyte surveys. The V BWD col I ected thi s
macrophyte data to identify the condi ti ons of plant growth throughout the lake. M acrophytes are the

macrophytes can i mpact the recreati onal use of a water body, they are cri ti cal to the ecosystem as
fish and wildlife habitat.
In both surveys, a diverse plant community was found wherever the water depth was I ess than
fourteen to f if teen feet. Most of the I ake i s I ess than ten feet deep and approximately 99 percent of
the lake is shallow enough for plant growth (Osgood, 1997). The lake's plant community consisted of
fifteen individual species. These species are common to Minnesota I ekes and provide good habitat

posy bl a that thi s f actor was rel aced to the predomi nance of aquati c pl ants i n Si I ver L ake
(e.g., nutrient uptake by attached algae growing on aquatic plants and/or nutrient uptake by
coontai I, a pl ant without roots that deri ves nutri ents f rom water).
In 1999, the VBWD found Eurasian watermi IfciI wherever the water depth was Iessthan fourteen or
f if teen f eet (see A ppendi x C-5.1). PI ant densi ti es ranged f rom I i ght to heavy, but were I i ght to
moderate i n most areas of the I ake. Four areas on the north and west s des of the I ake noted heavy
growths of Eurax an watermi Ifoi I, and native sped es were not present i n heavy growth areas. I n of I
other areas of the lake, the native plant community appeared to be successfully competing with
Eurasian watermilfoil.
The D N R surveyed macrophytes at 131 ocati ons wi thi n Si I ver Lake on M ay 13, 2005, and f ound
Eurasian watermi IfoiI in the southern poi ntsof their survey (see Appendix C-5.1).
The VBWD conducted amacrophyte survey of Silver Lakeon June 13, 2005. Eurasian watermilfoil
wasfound throughout the lake, and plant densities were much, much heavier than in 1999. The
coverage at the southern end of the lake was extremely dense (see Appendix C-5.1).

Eradi cati on of Eurasian watermi If oil from Si I ver Lake would be desirable to protect the I ake' s nati ve
plant community and habi tat f or fish and aquatic I if e. However, the DNR has indicated treatment of a •
Iake with herbicide rarely results in eradication of Eurasian watermi Ifal (Chip Welling, Personal
Communication, 2004). Hence, Eurasian watermi Ifoi I eradication is probably not a realistic goal for
Silver Lake. However, treatment of areas containing dense, monospecific growths of Eurasian
watermiIfal with an aquatic herbicide (2,4-D, Triclopyr, or Iow concentrations of Aquathol® K) is
recommended to protect the lake's native plant community. The VBWD should work with Ramsey
County and the cities of Map[ ewood and North St. Paul to determine areas in need of herbicide
treatment and to implement the needed treatment program.
In 1999, 1 i ght growths of curl yl eat pondweed were found i n most areas of the I ake. Nati ve vegetati on
appeared to be successfully competing with the curlyleat pondweed and preventing increases in its
density and coverage. Thus, Silver Lake appeared to be different from most Iakescontaining this
plant. Typi cal I y, once a I ake becomes infested with curl yl eat pondweed, this plant typical I y di spl aces
native vegetati on, thereby increasing its coverage and density. Curl yl eaf pondweed begins growing in
late August, grows throughout the winter at a slow rate, grows rapidly in the spring, and dies in early
summer. Native pl ants that grow from seed in the spring are unable to grow in areas ad ready occupied
by curl yl eat pondweed, and are di spl coed by this plant. Si l ver Lake's plant community includes two
native species, coontail (Ceratophyllumdemersum) and elodea (Elodea anadensis), that grow
throughout the wi inter and spri ng peri od. I t was bel i eyed that these nati ve sped es were preventi ng the
spread of curlyleaf pondweed in Silver Lake.
Although the coverage and density of curl yleat pondweed did not warrant concern based on the 1999 •
survey results, the VBWD conducted a June 13, 2005 to determine if the coverage and density of this
plant had changed. The survey found that curl yleaf pondweed's density and coverage had increased
since 1999 (see Appendix C-5.1). The DNR also conducted acurlyleaf pondweed survey on May 13,
2005, and noted curl yl eat pondweed in some of the northern sampling pants (see Appendix C-5.1).
Curl yl eat pondweed turi ons (simi I ar to seeds) and Eurasian watermi I f oil fragments can f I ow
downstream and i nfest downstream I akes. Further study of the posy bl e i mpacts of curl yl eat
pondweed and Eurasian watermi I f of I infestation of downstream lakes, including Long,
DeM ontrevi I I e, and Olson, i s recommended. The study will determine whether additional
management of these pl ant sped es i s warranted.

production. An inadequate phytopl ankton population reduces the lakes zoopl ankton population and
• adversely impacts the growth of the lake's fishery. However, excess phytopl ankton, especi el I y blue-
green algae, can i nterf ere with recreational usage of a lake and is considered problematic.
A I ate summer al gal bloom, dominated by green algae, was observed in SiI ver Lake during 1999.
Despite the algal bloom, the I ake's 1999 water transparency was general I y good, ranging from a I ow
of 1.0 meter to a high of 3.9 meters during the summer. Lowest measurements occurred in the I ate
summer during algal blooms The data suggest the I ake's benef i d ai uses are currently supported by
the I ake'sphytoplankton community. However, management of the I ake's algae is warranted to
prevent i ncreased al gal bl ooms and possi bl e i nterf erence wi th the I ake' s benef i a al uses.
The Iake! szoopiankton community isdominated by small -bodied forms Whilethese ani me] sprovide

states that although the Silver Lake outlet is located in the City of Oakdale, the City of North St. Paul
has been assuming responsibility for maintenance of the outlet. •
The VBWD's goals for Silver Lake are to:
• Address future intercommunity water quantity issues.
• Address existing flooding problems on Silver Lake.
• Prevent future flooding problems on Silver Lake.
5.1.3.1 Water Quantity Issues
Some homes adjacent to the lake experienced basement flooding in 1984 and 1985 when the lake
rose above Elevation 989.5. Whether this was entirely due to the lake elevation is not clear. The
DNR's ordinary high water elevation (OHW) is 989.7. According to the North St. Paul Flood
Insurance Study (FIS), the 100 year flood elevation of Silver Lake is 991.0. More recent hydrologic
model results (by Oakdale and VBWD) show the 100 -year flood elevation of the lake to be
approximately 0.5 foot lower. The North St. Paul Plan states that at least one homeowner could
possibly benefit from having the FIS maps revised. However, the Federal Emergency Management
Agency (FEMA) does not normally issue Letters of Map Amendment when proposed elevation
changes are less than one foot. Since the proposed drop in the Silver Lake flood level would be 0.5
foot, it is unlikely that FEMA would issue a Letter of Map Amendment for Silver Lake. Since the
City of North St. Paul will not pursue revising the FIS, the City and VBWD will continue to enforce .
the 991.0 flood level. The results of a 1976 VBWD survey found one home (Elevation 990.17) and
two garages (Elevation 989.97 and 990.87) on the west side of the lake within the FIS 100 year flood
plain and an additional four homes lower than Elevation 993.0 (the minimum building elevation for
land adjacent to Silver Lake).
Drawdown of Silver Lake occurs quickly compared to downstream lakes. This means that the lake
does not hold excess stormwater long enough to be of significant value in reducing downstream
flooding. Although the lake drains quickly, residents are very sensitive to small changes in lake level.
In 1989, the City of North St. Paul surveyed residents as part of their water management planning
process and the survey results identified water level control as an issue. As noted in the North St.
Paul plan, water level concerns (either too high or too low) received the most attention.

MINLEAP Modeling
The Minnesota Lake Eutrophication Analysis Procedure (M I NLEAP) is intended to be used as a
screening tool for estimating I ake condi ti ons and for identifying "problem" I akes M I N L EA P i s
parti cul arl y useful for identifying I akes requi ri ng "protection" versus those requiring " restorati on"
(Hei skary and Wi I son, 1990). In addition, M I NLEAP modeling by has been done in the past to
identify Minnesota lakes which may be in better or worse condition than they "should be" based on
their I ocati on, watershed area and lake basin morphometry (Hei skary and Wi I son, 1990).
Results of M I NLEAP modeling done by the V BWD in 2000 f or Si I ver Lake suggests that the lake
could achieve" better" water quality than is currently observed (Heiskary and Lindbloom, 1993).
M I N L EA P predicts a growi ng season mean total phosphorus concentrati on of approxi motel y 42 ug/L
versus 28-57 ug/L (observed i n the I ast ten years); a chl orophyl I a concentrati on of approxi matel y 15
Ng/L versus 2-9 Ng/L (observed in the last ten years); and summer average transparency of
1.6 meters versus 2.1-3.9 meters observed i n recent years The predi cted phosphorus conoentrati on
has a standard error of 16 Ng/L, whi ch means that the V BWD's water qual ity goal I i sled i n the 1995
PI an of 30 pg/L f or total phosphorus i s wi thi n the range of what i s real i sti cal I y alta nabl e f or Si I ver
Lake.
Vighi and Chiaudani Method
• V i ghi and Chi audani (1985) developed another method to determine the phosphorus concentration in
I akes that: are not affected by anthropogenic (human) inputs Asa result the phosphorus concentration
in a lake resulting from natural, background phosphorus I oadi ngs can be cal cul ated from information
about the lake's mean depth and alkalinity or conductivity. Alkalinity i s considered more usef ul for
thi s anal ysi s because i t i s I ess i of I uenced by the modif yi ng effect of anthropogeni c i nputs.

Appendix B-5.1 Additional Fishery Information
The DNR 2000 Lake Survey Report indicates:
• Bluegill, pumpkinseed, and hybrid sunfish were the most abundant fish captured, but most were
small in size, with less than ten percent over six inches long.
• Black crappie were present in low numbers with only a few over 8 inches long.
• Yellow perch were below the median for this lake type and nearly half of the yellow perch caught
were over nine inches long.
• Largemouth bass were moderately abundant with most fish measuring 12-16 inches long.
• Walleye numbers (3.5/gillnet) were within the historical range (2.0-5.5/gillnet) and averaged over
20 inches in length.
• Northern pike were present in higher numbers than any other year Silver Lake was surveyed. All
fish were age IV or less and most were under 25 inches long.
is
• Two tiger muskellunge were sampled. Both were from the 1998 stocking and were approximately
24 inches long.
• Yellow bullhead numbers reached historic highs in this survey, but were average for this type of •
lake. One-third of all fish were over 12 -inches long. Black bullhead numbers were low.
• White sucker were present in moderate numbers, ranging in size from 15-18 inches.

Dear Block Party Host:
The Maplewood police department, in cooperation with the Maplewood fire department
and parks and recreation department, coordinates the annual National Night Out
program. We are very pleased that you are coordinating your neighborhood block party.
This year's community event will take place on Tuesday, August 1 from 5:00 p.m. to 8:00
p.m. National Night Out is designed to:
1. Heighten crime, drug and violence prevention awareness.
2. Generate support for, and participate in, local anti-crime programs.
3. Strengthen neighborhood spirit and police community partnerships.
4. Send a message to criminals letting them know that neighborhoods are
organized and will not tolerate inappropriate behavior.
Maplewood has a strong tradition in the National Night Out program. We are expanding
this year's event to include more neighborhoods.
We will provide neighborhoods with 2 gallons of ice cream, 2 cases of root beer, straws,
spoons, ice cream scoops, limited National Night Out shirts, limited souvenir cups,
bubbles for youth, tattoos, cups, door prizes and certificates. The larger parties,
apartment complexes and high rises, will receive up to 4 gallons of ice cream and 6.
cases of root beer. All supplies are to be picked up on Monday, July 31. or Tuesday,
August 1. Supplies are to be picked up at the Public Works building, 1902 E. Co. Rd. B:
Map is enclosed.
This year we are adding a new venue to the event. We are teaming up with Second
Harvest Heartland for a food and fund drive. Donations will be picked up at your block
party on August 1. Please encourage participants to bring a donation.
Scheduled stops are also being coordinated for police and fire to stop by your
neighborhood party. These stops are limited in time so every party can be covered.
We look forward to your continued support and involvement in the National Night Out
program. It is only through your support that we can truly "take the bite out of crime."
If you have any questions please feel free to contact Pauline Staples at 651-249-2105,
Sergeant Flint Karis at 651-249-2652 or Lieutenant Kevin Rabbett at 651-249-2604.

UBACCU-FREE PARKS AND RECREATION STUDY
Summary of Findings
Park areas in Minnesota are used regularly by state residents. Tobacco use restrictions in outdoor
environments such as parks and recreation areas are being established in Minnesota and other states
across the U.S. The purpose of this study is to describe the support for tobacco -free park policies in
Minnesota. To learn more about the public's perceptions of these policies, we conducted a survey of
Minnesota residents. We also interviewed park and recreation professionals to ask specific questions
about tobacco -free policies in Minnesota.
Is secondhand smoke a problem?
Yes. Secondhand smoke is a recognized cause of acute and chronic diseases in nonsmokers, and is a
major source of indoor air pollution. Secondhand smoke is also responsible for an estimated 3,000 lung
cancer deaths and 38,000 heart disease deaths in nonsmoking individuals each year in the United States.
The most effective approach to reducing secondhand smoke exposure is to establish smoke-free
environments. Research has suggested that the adoption of smoke-free policies creates a change in
social norms around smoking, helps smokers reduce consumption or quit, and helps keep youth from
starting.
Public support for tobacco -free parks
A survey was sent to Minnesota residents by mail in summer 2004. Of the 1,500 respondents, 75% ha
o
used any park area in the past month. Overall, 70% of those surveyed supported tobacco -free policies for
outdoor park and recreation areas. The attitude of Twin Cities metro area residents was not different from
residents living in other parts of the state. Respondents expressed support for tobacco -free policies to:
• Reduce litter in park grounds.
• Avoid the health effects of secondhand smoke_
• Discourage youth smoking.
• Establish positive role models for youth.
• Promote community well-being.
Po/icy components
We also asked residents about the
components of tobacco -free park policies
(shown, right). Most people supported strong
policies that prohibit tobacco use in youth
areas, and asking policy violators to leave
park areas. Just over half (53%) of
respondents supported the prohibition of
tobacco use in all parks at all times. Smokers
were the only group generally less supportive
of these policies.
Preferences for tobacco -free park
policies among Minnesota residents, 2004
Golfers
Thirty-five percent of our sample were golfers. Most golfers (81 %) were non-smokers, and 74% of non-*
smoking golfers supported tobacco -free park policies. We found that being a golfer did not make a
difference in support for tobacco -free policies, but being a smoker did.
