AGENDA ITEM S.A.
STAFF ORIGINATOR: Paul Bengtson
P &Z MEETING DATE: June 9, 2010
TOPIC: CONTINUED PUBLIC HEARING
Amendments to Zoning Ordinance and Subdivision
regulations Chapter of City Code Regarding Development
in Environmentally Sensitive Areas, Tree Preservation,
Landscaping, Planned Unit Developments, and Platting
BACKGROUND
The Environmental Board discussed the site layout, landscaping, and tree preservation
standards on May 4. The P & Z discussed those and the collaborative design process on May
12. Some revisions have occurred since those meetings. The revisions are attached to this
memo for discussions by the Environmental Board on June 2 and the P & Z on June 9.
Since the late 1990s Lino Lakes has been pursuing a more environmentally sound means of
handling new development. The city's Handbook for Environmental Planning and
Conservation Development was printed in 1999. We followed that with the 2004 Parks,
Natural Open Space /Greenways and Trail Plan. The I -35E Corridor Alternative Urban
Areawide Review in 2005 established a "conservation design framework" for all development
within the study area. The draft new Comprehensive Plan further promotes the conservation
design principles laid out in all these documents. Chapter 2 creates the Resource Management
System Plan, establishing an open space system that corresponds with Environmentally
Sensitive Areas created by plans and rules of the Rice Creek Watershed District.
Now the City is creating and amending official controls to implement the ideas and plans. The
subjects of the public hearing tonight are sections of the zoning ordinance and subdivision
regulations, the primary controls for regulating new development. (A new stormwater
management ordinance also is in the works.) All the different ordinance requirements need to
work together toward the goals of preserving and creating a city wide greenway system through
the identification and protection of Environmentally Sensitive Areas.
The Rice Creek Watershed District is the governmental entity that regulates wetland impacts
and the public drainage ditch system. Extensive environmental research by the District and
Lino Lakes resulted in the creation of an overall Environmentally Sensitive Areas (ESAs) map
for Lino Lakes. The District's new rule RMP -3 is designed to identify and protect ESAs on
individual development sites. The District's rules protect wetlands and include requirements
for stormwater design. The Lino Lakes ordinances are intended to provide standards for
aspects of development that are beyond the scope of the Watershed District's authorities. In
this way, the City and the Watershed District's actions are partners in creating the citywide
greenway system of ESAs.
City staff have worked with Bonestroo to prepare draft new site layout performance standards
and landscaping and tree preservations standards. All of these are intended to apply to all new
plats, site plans for commercial /industrial /institutional uses, conditional use permits —in fact,
all new development in the city. The site layout performance standards are new. The
landscaping and tree standards would replace the existing sections of the zoning ordinance.
The process for reviewing new development is as important as the regulatory standards that
must be met. While we have been practicing the collaborative method for the past few years,
the new process sections will codify those practices into ordinance form. The new
collaborative design sections of the subdivision regulations would apply to all new plats and
planned unit developments. The PUD section of the zoning ordinance would refer to those
sections of the subdivision regulations. This will eliminate redundant and potentially
conflicting requirements in the current ordinance.
All these documents are drafts that are undergoing revision. It is likely the levels of
requirements now in the tables will be pared down. We also will need to clarify some things.
For example, tree preservation requirements for a development project should be different from
a builder getting a permit for a house and from a homeowner removing a tree in his yard.
ENVIRONMENTAL BOARD
At the June 2, 2010 meeting the Environmental Board recommended approval of the ordinance
amendments, with the following corrections and comments:
Attachment 1: Site Layout Performance Standards – REVISED May 26, 2010
Recommended for approval as written
Attachment 2: Landscaping and Tree Preservation Standards – REVISED May 26, 2010
Page 4 NO SPECIFIC CHANGE RECOMMENDED
Environmental Board would like to encourage developers to exceed the
requirements for landscaping materials, though offering incentives might not be
warranted.
Staff commented that the PUD process allows the flexibility to increasing some
landscaping requirements in exchange for leniency elsewhere.

Memorandum Bonestroo
To: Michael Grochala, AICP, Community Development Director, City of Lino Lakes
From: Ciara Schlichting, AICP
Date: May 26, 2010
Re: Draft Ordinance Language
The purpose of this memo is to transmit revised draft ordinance language for the Environmental Board to
review at their meeting on June 2, 2010 and for the Planning and Zoning Board to review at their
meeting on June 9, 2010. The proposed revisions are intended to address comments received from the
Environmental Board, Planning and Zoning Board, and city staff. No public comments were received
during the public hearing held May 12, 2010 (the public hearing is still open). The attachments to this
memo include the following:
Attachment 1: Site Layout Performance Standards
The Site Layout Performance Standards include four minor revisions. Since the revisions are minor only a
"tracked changes" version of the proposed language is being transmitted. The revisions are intended to
address the following comments:
1. The need to clarify that surface water management needs to be based on predevelopment
conditions.
2. Remove reference to tree preservation levels (e.g., Level T -1, T -2) since labeling the
requirements as "levels" was removed from the tree preservation standards.
Attachment 2: Landscaping and Tree Preservation Standards
The Landscaping and Tree Preservation Standards contain numerous minor revisions; therefore, both a
"tracked changes" and "clean" version of the draft ordinance language is being transmitted. The
revisions are intended to address the following comments:
1. Overall, the text was reorganized to make the language more "user friendly" and to simplify
administration of the standards. Most of these revisions did not result in substantive changes to
the standards. For example, the concept of "levels" was removed; however, the general intent of
the standards remain although the numbers (e.g., planting requirements) may vary slightly from
the previous version.
2. Require one canopy coverage percent (e.g., 40 %) for all uses rather than have two levels.
3. Increase the incentive (e.g., assigned canopy coverage value) to have more than two trees in an
interior parking lot island.
4. Increase minimum soil volume requirements for trees in a single or shared bed.
5. Clarify that existing lots with existing buildings can remove trees without triggering mitigation
requirements.
6. Clarify that the non - compliance measures also apply to tree preservation plans.

Attachment 1: Site Layout Performance Standards - REVISED May 26, 2010 Page 1
E. Site Layout Performance Standards. All uses shall comply with the requirements of this section.
1. Purpose. The City developed a Resource Management System Plan based on a water and
natural resource inventory and assessment and the vision, goals and policies developed through
the comprehensive planning process. The performance standards established in this section are
for the purposes of accommodating development that protects, conserves and enhances the
city's water and natural resources consistent with Comprehensive Plan goals.
2. Natural Resource Conservation. The two overall components of natural resource
conservation are the surface water management system and environmentally sensitive areas.
a. Surface Water Management System. The design of the surface water management
system shall be based on preserving predevelopment hydrology (i.e., existing surface water
runoff volumes and rates) and environmentally sensitive areas to the extent practical in
accordance with the following minimum performance standards:
1) Establish the wetland preservation corridor in accordance with watershed district rules.
2) Reduce the need for surface water management facilities by preserving and integrating
natural topography, soils and site drainage into the surface water management system
to the degree they can accommodate the additional flow and volume of water without
compromising water quality.
3) The preferred conveyance strategy is to transport wherever possible untreated and
treated runoff in conveyance facilities open to the atmosphere (e.g., swales, vegetated
buffer strips, energy- dissipating structures, etc.) rather than through enclosed pipes, so
as to decrease runoff velocity, allow for natural infiltration, allow suspended sediment
particles to settle, and to remove pollutants.
4) Site grading shall be minimized to the maximum extent reasonable to minimize impacts
to environmentally sensitive areas.
5) The surface water management system shall be designed to meet the performance
standards in the Lino Lakes Stormwater Management Ordinance, Lino Lakes Stormwater
Design Manual & RCWD Rules.
b. Environmentally Sensitive Areas (ESAs). The design of the site shall be based on
protecting, conserving, and enhancing ESAs to the extent practical while allowing for
equitable economic return. ESAs shall be identified and categorized through the site
planning process.
1) ESA Identification and Categorization. During the resource inventory and site
analysis process for a property that has an ESA, all ESA features on the site shall be
identified on the resource inventory map. Landscape -scale ESAs are mapped and on file
with the City. Balancing the goals of natural resource protection and conservation with
land use goals requires prioritizing ESAs. ESA categories (i.e., Natural Resource
Protected Area) are listed in descending order from the highest to the lowest level of
priority. ESA features (i.e., wetland preservation corridor, natural areas, etc.) listed
under each category are not prioritized.
Attachment 1: Site Layout Performance Standards Page 2
a) Natural Resource Protected Areas. These areas include:
i. Streams
ii. Lakes
iii. Wetland Preservation Corridor (WPC): Areas designated as wetland preservation
corridor on the landscape -scale WPC boundary shown on Figure 1 in Rice Creek
Watershed District Rule RMP 3, as amended. The wetland preservation corridor
may include:
• Wetlands
• Natural and Semi- Natural Areas: Areas designated as Natural and Semi -
Natural Areas in accordance with Minnesota Land Cover Classification
System (MLCCS). Natural areas are comprised of more than 50% native
plants. Semi - Natural areas are comprised of Tess than 50% native plants.
• Floodplain: Areas designated as 100-year floodplain and regulated under
the Lino Lakes Floodplain Ordinance.
b) Natural Resource Conservation Areas. These areas include:
i. Wetlands Non - contiguous to the WPC.
ii. Natural and Semi - Natural Areas: Areas designated as Natural and Semi - Natural
Areas in accordance with the MLCCS. Natural areas are comprised of more than
50% native plants. Semi - Natural areas are comprised of Tess than 50% native
plants.
iii. Floodplain. Areas designated as 100 -year floodplain and regulated under the
Lino Lakes Floodplain Ordinance.
c) Natural Resource Corridor Enhancement Areas: Corridors that provide
connections between environmentally sensitive areas to establish a more contiguous
and complete natural open space system.
2) Minimum Performance Standards for ESAs. The following are the minimum
performance standards that shall be used in the site planning process to maximize the
function and value of ESAs, to minimize adverse impacts to ESAs, and to allow
development activities that will provide equitable economic return.
a) Natural Resource Protected Areas. These areas shall be protected and
incorporated into new development to maintain the function and value of water
resources and associated upland habitat areas while allowing for passive
recreational use. Development within natural resource protected areas is largely
controlled, and where applicable, prohibited under established regulations. Specific
performance standards within a Natural Resource Protected Area are as follows:
i. Surface Water. Incorporate lakes and streams into the surface water
management system consistent with applicable watershed district, State of
Minnesota, and Federal statutes and rules (e.g., pre -treat runoff before
discharging into a lake or stream, volume control, and rate control).

ii. Wetland Preservation Corridor. Establish the WPC in accordance with
watershed district rules. The delineated WPC will be established during the site
planning process.
iii. Vegetated Wetland Buffer. Establish an upland buffer of native vegetation
around wetlands within the WPC to maintain water quality and habitat.
Development is regulated in the following manner:
(a) The buffer shall average at least 50 feet in width, measure at least 25 feet
at all points, and meet the average width at all points of concentrated
inflow. The location of the buffer shall maximize the protection of ESAs.
(b) The vegetated wetland buffer and upland habitat area must meet the
requirements in RCWD RMP -3 and the Vadnais Lake Area Water
Management Organization, as amended
(c) Structures shall be setback a minimum of 10 feet from the edge of the
wetland buffer.
iv. Natural and Semi- Natural Areas. Conserve and enhance the function and
value of these areas for habitat, water quality, surface water management,
aesthetics, and passive recreational use.
(a) Suitable habitat for rare, threatened, or endangered species shall be
protected to the extent practical.
(b) The Lcvcl Two (T 3) tree preservation and mitigation requirements in
Section 3. Subd.4.Q shall apply to Natural Resource Protected Areas.
(c) Prairie and other non -woody natural and semi- natural communities shall be
considered for protection, restoration, and /or inclusion in the surface water
management system.
(d) Structures shall be setback a minimum of 10 feet from the edge of
protected natural and semi - natural areas.
b) Natural Resource Conservation Areas. These areas shall be conserved to
maintain the function and value of the area while allowing encroachment and
disturbance to accommodate development. Specific performance standards within a
Natural Resource Conservation Area are as follows:
i. Natural and Semi- Natural Areas. Conserve and enhance the function and
value of these areas for habitat, water quality, surface water management,
aesthetics, and passive recreational use.
(a) Suitable habitat for rare, threatened, or endangered species shall be
protected to the extent practical.
(b) The Lcvcl Two (T 2) tree preservation and mitigation requirements in
Section 3. Subd.4.Q shall apply to Natural Resource Conservation Areas.
(c) Prairie and other non -woody natural and semi- natural communities shall be
considered for protection, restoration, and /or inclusion in the surface water
management system.
Attachment 1: Site Layout Performance Standards Page 4
(d) Structures shall be setback a minimum of 10 feet from the edge of
protected natural and semi - natural areas.
ii. Wetlands Non - contiguous to the WPC: These areas shall be conserved in
accordance with applicable watershed district and Army Corps of Engineers
rules and permit requirements, as amended.
iii. Vegetated Wetland Buffer. Establish an upland buffer of native vegetation
to wetlands non - contiguous to WPC to maintain water quality and habitat.
(a) The buffer width must be at least 25 feet adjacent to the entire wetland.
The location of the buffer should maximize the protection of ESAs.
(b) The vegetated wetland buffer and upland habitat area must meet the
requirements in RCWD RMP -3 and the Vadnais Lake Area Water
Management Organization, as amended.
(c) Structures shall be setback a minimum of 10 feet from the edge of the
wetland buffer.
c) Natural Resource Corridor Enhancement Areas. These corridors shall be
established to provide contiguous and complete natural open space system, surface
water conveyance, and passive recreational uses. Specific performance standards
for Natural Resource Corridor Enhancement Areas are as follows:
i. Corridors should minimize natural resource fragmentation by creating
connections within and between natural resource protected areas or natural
resource conservation areas located on site and on adjacent properties.
ii. Corridors should be established where there is a convergence of multiple
features, such as surface water management areas, natural and semi- natural
areas, and existing or proposed trail corridors.
iii. The Ccvcl Two (T 2) tree preservation and mitigation requirements in Section 3.
Subd.4.Q shall apply within Natural Resource Corridor Enhancement Areas.
3) Wetland Buffer and Upland Habitat Requirements.
a) As a condition of approval, a property owner must record a declaration in a form
approved by the City establishing vegetated wetland buffer area adjacent to the
delineated edge of a wetland and upland habitat defined as an ESA through the site
planning process. The declaration must state that on further subdivision of the
property, each subdivided lot of record shall meet the monumentation requirement
of paragraph E.2.b.3.b. On public land or right -of -way, in place of a recorded
declaration, the public owner may execute a written maintenance agreement with
the City. The maintenance agreement will state that if the land containing the buffer
or upland habitat area is conveyed to a private party, the seller must record a
declaration for maintenance in a form approved by the City.
b) Buffer or upland habitat area is to be indicated by permanent, freestanding markers
at the buffer or habitat area upland edge, with a design and text approved by City
staff in writing. A marker shall be placed at each lot line and at all angle and curve
points, with additional markers at an interval of no more than 200 feet. On public
land or right -of -way, the monumentation requirement may be satisfied by the use of
•
•
•
•
Attachment 1: Site Layout Performance Standards Page 5
markers flush to the ground, breakaway markers of durable material, or a
vegetation maintenance plan approved by City staff in writing.
c) The application must include a natural resource management plan for City approval
that includes the following: site inventory, management goals, management
activities, maintenance activities, monitoring activities, funding mechanisms, and
any other information requested by City staff.
d) The buffer or upland habitat area will consist of vegetated land, primarily plant
species native to this region that is not otherwise disturbed, except for periodic
cutting or burning that promotes the health of the buffer or upland habitat area,
actions to address disease or invasive species, or other actions to maintain or
improve buffer or habitat area quality, each as approved in writing by City staff.
The following are prohibited: land that is cultivated; cropped; pastured; mowed;
fertilized; used as a site for depositing snow removed from roads, driveways or
parking Tots; or subject to the placement of mulch or yard waste. For public road
authorities and stormwater system maintenance, the terms of this subsection will be
modified as necessary to accommodate safety and maintenance feasibility needs.
e) Wetland buffer and upland habitat area may be disturbed to alter land contours or
improve buffer and upland habitat function if the following criteria are met:
i. An erosion control plan is submitted under which:
• alterations are designed and conducted to expose the smallest amount
of disturbed ground for the shortest time possible;
• fill or excavated material is not placed to create an unstable slope;
• mulches or similar materials are used for temporary soil coverage; and
• permanent native vegetation is established as soon as possible.
ii. Wooded buffer and native riparian canopy trees are left intact.
iii. When disturbance is completed:
• sheet flow characteristics within the buffer are improved;
• average slope is no steeper than preexisting average slope or 5:1
(horizontal:vertical), whichever is less steep; however, preexisting slopes
steeper than 5:1 containing dense native vegetation will not require
regrading;
• the top 18 inches of the soil profile is not compacted, has a permeability
at least equal to the permeability of the preexisting soil in an
uncompacted state and has organic matter content of between five and
15 percent; and
• habitat diversity and riparian shading are maintained or improved.
iv. A re-vegetation plan is submitted specifying removal of invasive species and
establishment of native vegetation suited to the location.
v. A recorded declaration or, for a public entity, maintenance agreement is
submitted that states that for three years after the site is stabilized, the
Attachment 1: Site Layout Performance Standards Page 6
property owner will correct erosion, maintain and replace vegetation, and
remove invasive species to establish permanent vegetation according to the re-
vegetation plan.
vi. Disturbance is not likely to result in erosion, slope failure or a failure to establish
vegetation due to existing or proposed slope, soil type, root structure or
proposed construction methods.
f) No above- or below- ground structure or impervious surface may be placed within
the buffer or upland habitat area permanently or temporarily, except as follows:
i. A public utility, or a structure associated with a public utility, may be located
within a buffer or upland habitat area on a demonstration that there is no
reasonable alternative that avoids or reduces the proposed buffer intrusion. The
utility or structure shall minimize the area of permanent vegetative disturbance.
ii. Stormwater features that are vegetated consistent with E.2.b.3.d may be
located within buffer on site - specific approval.
iii. Buffer or upland habitat area may enclose a linear surface no more than 10 feet
in width and, for buffer, no less than 25 feet from the delineated wetland edge
for non - motorized travel if wetland habitat will not be measurably reduced. Trail
edge mowing is not permitted.
3. Disconnect and Distribute Stormwater. The guidelines established in this section are for
the purposes of maximizing the use of pervious areas at the site to help filter and infiltrate runoff
generated from impervious areas and to spread excess runoff over pervious areas.
a. Compost and Amended Soils. To recover soil porosity lost due to compaction, soils
should be amended to allow for adequate water holding capacity for plant growth and
infiltration of runoff.
b. Disconnect Impervious Surfaces. Runoff from impervious surfaces such as parking Tots,
driveways, and sidewalks should be routed to adjacent pervious areas to be filtered or
infiltrated into the soil.
c. Rooftop Disconnection. Runoff from rooftops should be spread over lawns and other
pervious areas.
4. Reduce Impervious Cover. Less impervious cover directly results in Tess stormwater runoff
and pollutant loads generated at the site. Impervious surface should be reduced to the extent
practical.

Q. Landscaping and Tree Preservation Standards
1 Purpose. To establish landscaping standards and tree preservation requirements to promote
high quality site development, compatibility of uses, biodiversity, tree preservation,
and to enhance the health, safety and general welfare of the residents of the community.
2 Definitions. The following words and terms, wherever they occur in this Ordinance, shall be
interpreted as herein defined:
Approved Species: Species found on the City maintained list which may be planted. The City
may restrict applicant's use of approved species in certain situations where the species may
be inappropriate.
Basic use area: Area dedicated to site's praey -use, including buildings, parking, loading,
driveways, streets, outbuildings, trash enclosures, utilities, landscaping, and grading

e. The City may allow flexibility in landscape requirements if there are conflicts with solar
power, wind power, water harvesting, food production or other innovative measures
proposed for the site.
f. The landscape plan shall be compared to all applicable CPTED (Crime Prevention
Through Environmental Design) standards and reviewed by the police department.
g. Trees and shrubs shall not be planted in the right of way without City authorization.
10. Landscaping Guidelines and Technical Requirements: The purpose of the guidelines
and technical requirements is to encourage plant longevity, minimize maintenance, and
mitigate conflicts with other site features. An initial investment in high quality materials,
careful design and planning, and proper construction techniques can result in plant longevity
and long term maintenance cost reduction.
a. Species Selection: Appropriate species selection is critical to maximize the benefits of
plant materials. Healthy, long lived plants well suited to a site will reduce maintenance
and replacement costs, while providing the most aesthetic and environmental gain.
Native species in the built environment will supplement and connect the existing natural
areas. Diversity is also important for an overall healthy and balanced landscape that is
less susceptible to pests and disease.
1) The City shall maintain a list of approved species. The list is based on Lino Lakes
area natural vegetative cover and includes additional hardy, non - invasive species.
Approved species are classified by size. For each site, plants shall be selected based
on mature size and adaptability to site conditions, such as microclimate, salt,
pollution and other factors. The list of approved species is not exhaustive.
Applicants requesting to plant a species not on the list shall submit species name,
height, width, form, hardiness zone, and other relevant information. The City shall
classify new species based on tree size standards. For large projects the City may
require applicants to comply with the following requirements:
i. Species diversity
ii. A minimum percentage of native species
iii. A minimum percentage of large trees
iv. A minimum percentage of evergreen trees.
2) The City shall maintain a list of prohibited species. This list includes species that are
invasive or have other negative characteristics that may lead to ecological damage.
3) Exposed soil is not allowed. All areas not covered by a structure or hardscape shall
be planted and mulched in accordance with the following:
i. In areas with low pedestrian traffic, the use of low maintenance turf, typically
fescue blends, is encouraged. In areas of high pedestrian traffic, the use of turf
mixes with a higher percentage of rye grass is encouraged.
ii. Turf in areas near roads and parking lots shall be salt tolerant.
• iii. Groundcovers shall be turf, perennials, annuals, small grasses, or low spreading
shrubs. Type of groundcover should be determined by site conditions and
1 Attachment 2: Landscaping and Tree Preservation Standards - REVISED May 26, 2010
anticipated use. Mulch is acceptable in landscape beds and areas not suitable for
living groundcovers.
iv. Hardy perennial forbs and ornamental grasses should be used in car overhang
areas and places where snow may be stored.
4) Annual plantings should be minimized within 10' of a tree. The process of frequently
replanting may damage the tree's shallow root system.
5) Seed mixes should be used in large expanses of naturalized areas. The City shall
maintain a list of approved seed mixes. Where seed mixes are used, the City may
request that visible edge treatments be planted with more deliberate groupings of
flowering plants.
6) A permanent solid edge such as a 6" concrete, stone or other barrier is required
between native seeded areas and turf unless otherwise approved by the City.
b. Planting Requirements:
1) To promote development of a large, healthy canopy, trees shall be planted in
accordance with the requirements in the following table and illustration:

Attachment 2: Landscaping and Tree Preservation Standards - REVISED May 26, 2010 Page 11
2) Soils: Landscaped areas need high quality soils that retain moisture for plants to use,
but drain adequately. Soil shall be uncompacted existing soil, new planting soil or
engineered soils designed to allow plant growth. Proper soil preparation helps to
ensure long term survival of the plants and to reduce the need for ongoing
maintenance, additives, and pest control. If soil compaction exceeds 1400 kPa (200
psi) at the time of planting, the soil shall be loosened. Preexisting soils may be used
and should be protected from compaction during construction.
3) Mulch: Mulch helps plant health by keeping the soil moist, protecting soil nutrients,
preventing erosion, encouraging infiltration, and inhibiting weed growth. Mulch from
decomposing materials such as wood chips enriches the soil over time. Although
decomposing mulch needs to be replenished approximately twice a year to maintain
adequate thickness, once plants grow together there is often need for little or no
mulch. Mulch shall comply with the following requirements:
a) Provide mulch at a depth of 3 -4" for wood chips, 4 -6" for shredded bark and 3 -4"
for rocks or other non - organic matter.
b) Provide a 3' minimum diameter mulch ring at the base of trees.
c) Prohibit mounding mulch at the bases of trees, or allowing mulch within 4" of
plant stems and trunks, as this will cause them to rot.
• d) If used, only water permeable fabric is permitted as a weed barrier.
•
e) Leave one inch of space from the top of the mulch layer to adjacent hardscape
surfaces to prevent spilling.
f) The City may limit certain types of mulch in areas where safety or spilling may be
an issue.
g)
Mulch should not be mixed with underlying soil.
4) Fertilizer: When fertilizer is used, organic and slow release fertilizers are
recommended.
5) Drainage: Tree planting pits shall drain adequately. Drainage for trees may be
accomplished through the use of non - compacted and well draining soils. The City
may require the following drainage test: Dig 8" diameter holes 1' deep and fill with
water. If the holes do not drain within 24 hours adjust bed design or composition in
order to achieve proper drainage. If the underlying soils retain water, the applicant
shall provide additional drainage measures.
6) Tree protection after construction: Bollards, barriers, or spacing may be necessary
to protect trees from cars. Bike parking should be included to discourage locking
bikes to trees. For tree protection during construction see Section Q.15.
c. Tree and Infrastructure Placement: Tree placement should be given consideration when
locating overhead and underground utilities. Service utilities should be located outside of
plant beds where they may conflict with tree plantings. Consider using conduits for
buried utilities to allow future work with less disruption to roots. The clearances in the
Attachment 2: Landscaping and Tree Preservation Standards - REVISED May 26, 2010
following table are recommended from the center of the tree trunk to avoid future
conflicts:

d. Clear Vision Area for Local Residential Roads: Shall
mean the triangular area of a corner lot formed by the
intersection of the right -of -way (ROW) lines and a line
connecting them at points 20' from the intersection
unless otherwise directed by the City (see illustration).
Within this area, visibility shall be unobstructed

* City may limit bare root plantings in areas of high visibility. In selected situations the City may
allow ten (10) whip bare root plantings, or five (5) 3/4" caliper bare root plantings to be
substituted for 1 large tree. Bare root plantings must be protected with rodent guards.
f. All boulevard trees shall be balled and burlapped and a minimum size of 2" caliper
g. Installation and Maintenance
1) Installation: Proper planting is the first and most important step toward establishing
healthy and low maintenance vegetation. All plantings shall be installed in
accordance with standard practices of horticultural professionals.
•

•
•
Attachment 2: Landscaping and Tree Preservation Standards - REVISED May 26, 2010 Page 13
Stem girdling roots are often fatal for trees that have been planted too deep or have
mulch or soil built up around the trunk. All trees shall be planted so that the root
flare (where the trunk widens out just above the roots) is visible above the ground
level and the highest large root is within 1/2" of the ground surface. All adventitious
roots should be cut away at the time of planting to avoid the formation of stem
girdling roots.
2) Maintenance: The property owner or if applicable, the homeowners association, shall
be responsible for maintenance of landscape elements (plants, structures, pavement,
etc.) so as to present a neat and aesthetically pleasing appearance free of any
unhealthy or potentially unsafe conditions. Landscaping shall be maintained to be
weed -free, healthy, trimmed, mown, edged, reseeded, pruned, and replaced with
similar plant species if necessary. Specific requirements for watering and pruning
follow:
i. Watering: All plantings require regular watering for at least the first three years
to get established. Once the root system has developed, many hardy plants,
especially native plants, may only need supplemental watering in drought
conditions.
Cultured turf areas and landscape berms shall be permanently irrigated. The
City may allow low maintenance turf to be non - irrigated if a method for
supplemental watering, such as a spigot or rain barrel, is provided.
For landscape beds ongoing irrigation may be provided through a permanent or
temporary system, or by hand. (Note: typical installed irrigation systems do not
provide adequate water for new trees.) Permanent irrigation systems with an
automatic controller shall utilize rain sensing technology. Overspray should not
fall outside of the landscaped area. Water efficient drip or underground
irrigation is required in shrub and groundcover landscape beds for permanent
systems. Temporary systems may use spray irrigation for shrubs or plugs. See
Water Conservation Ordinance for additional watering requirements.
ii. Pruning: Plants shall be pruned to avoid conflict with other structures, remove
dead or diseased limbs and for optimum shaping. The City recommends that
trees be pruned by a certified arborist every 4 -7 years, which can help reduce
maintenance costs. Topping or extreme crown reduction is prohibited unless the
tree is a safety hazard or such measures are approved by the City.
Trees overhanging walkways should be pruned up to 7' when mature. Trees
overhanging streets should be pruned up to 10' when mature. Smaller trees
should receive limited pruning appropriate to the size and age of the tree.
Branches that are hazardous for any reason shall be removed immediately. The
City may direct pruning.
The property owner or if applicable, the homeowners association, shall be
responsible for removing any trees or shrubs or parts thereof that are dead,
diseased or overhang or interfere with traffic control devices, public sidewalks, or
rights -of -way.
Attachment 2: Landscaping and Tree Preservation Standards - REVISED May 26, 2010
11. Tree Preservation and Mitigation Standardsi}uirentents: The purpose of these
requirements is to protect valuable trees and stands of vegetation, while not interfering with
landowners' reasonable use and development of property. The goal is to minimize
unnecessary loss of habitat, biodiversity and forest resources and to replace removed trees in
areas where tree cover is most critical. Except where specifically excepted, tree preservation
and mitigation requirements apply to all plats, site plans, conditional use permits, interim use
permits, excavating, grading, building, or other similar activity.

12. Tree Survey:
a. A tree survey is required for all property that contains a deciduous tree greater than 6"
dbh or an evergreen tree greater than 12' tall.
b. The tree survey shall be the basis for the tree preservation plan, tree mitigation
requirements, and the use of existing trees to fulfill landscape requirements.
c. The tree survey shall provide the following information:
1) in the basic use area and other areas where tree removal is proposed, for all
deciduous trees over 6" dbh and all evergreen trees greater than 12' tall:
L tree species
il. size
III. location
iv. dripline
v. tree condition
2) the location of the combined driplines of all tree stands designated for preservation
trcc stands on the development property

trees greater than 12' tall where the dripline is within 5' root ,._tend; ofete the
development property.
d. For a new plat or new Planned Unit Development, the tree survey shall be one plan sheet
and the tree preservation plan shall be a separate plan sheet.
e. For a building permit for a new structure on an existing lot, the tree survey and
preservation information may be induded on the lot survey typically reauired for a
building permit instead of on a separate document. For a building permit for an addition
to an existing structure, the tree survey information may be provided in an informal
medium that sufficiently conveys the information.
f. At the City's discretion, the tree survey requirement may be waived under the following
circumstances:
1) Deciduous trees greater than 6" dbh or evergreen trees greater than 12' tall will not
be removed er -and are not likely to be impacted by construction.
2) Deciduous trees greater than 6" dbh or evergreen trees greater than 12' tall will only
be removed within the basic use area and the basic use area is not an ESA.
13. Tree PFeteetienPreservation Plan:
a. A tree preteetiernpreservation plan shall be required for all soil disturbance activities
where tree preservation and mitigation requirements apply in accordance with Q.11.a. A
tree preteetieepreservation plan shows how pr-etectienpreservation and mitigation
requirements will be met and how preserved trees will be protected during construction
and other potentially harmful activities.
1 Attachment 2: Landscaping and Tree Preservation Standards - REVISED May 26, 2010
b. The tree fweteetienpreservation plan shall be based on the tree survey.
c. If a tree survey shows that no desirable deciduous trees over 6" dbh or evergreen trees
greater than 12' in height on the development property or adjacent properties are near
the construction area, the City may waive the tree preservation plan
requirement.
d. A tree protectionpreservation plan shall include: the basic use area, the disturbance area,
tree size (dbh), species, condition, location, and root proMection zone (5' out from the
dripline) for all deciduous trees over 6`1 dbh or evergreen trees greater than 12' tall to be
preserved or the combined root protection zone of all stands of trees designated for
pretectienpreservation, whichever is applicable. The plan shall show location and type of
tree protection fence, staging areas, and concrete washout areas. Fencing shall be
installed and inspected by the City prior to soil disturbance. The plan shall show
directional felling if necessary to avoid damage to adjacent trees.
e. Trees to be preserved shall be tagged in the field and keyed to the tree
preteetienpreservation plan. The City may inspect the trees to verify compliance with the
pr-eteetieRpreservation plan at any time during construction.
f. The tree preservation plan shourld -shall not conflict with natural resource
management plan required for environmentally sensitive areas. See Section 2, Subd.
6.E.2.b.
g.
See the Stormwater Ordinance for other construction related requirements.
14. Individual Lot Tree Preservation Plan: To be determined.
15. Tree ProteetionPreservation During Construction: Trees that are to be preserved
must be protected by the following methods unless otherwise approved by the City.
1) Tree protection fencing shall be installed and maintained 5' out from the identified
drip line of the trees (root protection zone) prior to soil disturbance. Fencing shall be
a minimum of 4' high and of a highly visible material, such as snow fence or
polyethylene laminar safety netting, and must be standing throughout the
construction process. Cut roots with clean, pruning cuts at the fence line prior to
fence installation to avoid later tearing of the roots. Signage should be installed to
instruct workers to stay out of the root protection zone.
2) Areas where development must encroach upon the root protection zone must be
identified on the tree pretectienpreservation plan in which case the fencing shall be
installed at that edge.
3) No actions that may harm the health of the tree, including, but not limited to
construction, traffic, compaction, storage of equipment or materials, including soil,
grading, or concrete washout areas may occur in the root protection zone.
4) Trees damaged by construction, or with more than thirty percent of the roots
disturbed, shall be counted as removed and mitigated at applicable rates.
16. Non - Compliance: If the City finds that the property is not in compliance with the approved
landscaping plan or tree preservation plan, it shall inform the property owner or if applicable,
the homeowners association, regarding the non - compliance and describe, in writing, the
steps needed to bring the property into compliance within a reasonable timeframe, not to
exceed sixty (60) calendar days.

STAFF ORIGINATOR: Paul Bengtson
P &Z MEETING DATE: June 9, 2010
TOPIC: Discussion of Outdoor Sales / Farmer's Markets
BACKGROUND
The Board had previously asked staff to review exterior sales events, and the following
information has been gathered to discuss the topic further. For discussion purposes, staff has
split these types of uses into four categories.
1. Roadside Stands
Roadside Stands are meant strictly for the sale of agricultural products grown/cultivated
on the site. The current ordinance does not define this use, but it is listed as permitted
only in Rural zoning districts, and the following section is referred to:
Section 3,Subd. 4.D. Accessory Buildings and Structures.
7. Roadside Stands. Seasonal, temporary roadside stands for the sale of
agricultural products shall be permitted if:
a. They are located in a zoning district which makes a specific
allowance for such use; and
b. They are located upon the lot on which the produce is grown.
c. They are erected at least sixty (60) feet back from the nearest
edge of the roadway surface; and
b. Adequate parking space is provided off the road right -of -way and
safe vehicular access and movements are assured.
2. Accessory to Retail
The Ordinance currently allows as an Accessory Use in the NB, LB and GB zoning
districts, "Outside services, sales, and equipment rental accessory to the principal use
and limited in area to twenty -five (25) percent of the gross floor area of the principal
building.
•
3. Open Sales Lot / Outdoor Sales Lot as Principal Use
The Ordinance currently allows as a Conditional Use in the GB zoning district,
"Outdoor Sales Lots (not outdoor storage) ". The definition currently included in the
ordinance is:
Open Sales Lot. Any open land use or occupied for the purpose of
buying, selling, and/or renting merchandise and for the storing of the
same prior to sale.
The conditions for an `Outdoor Sales Lot' in the GB (General Business) district are as
follows:
Outdoor sales lots (not outdoor storage) provided that:
a. Outside sales areas are fenced or screened from view of
neighboring residential uses or an abutting residential district in
compliance with Section 3, Subd. 4.Q of this Ordinance.
b. Outside services and sales are associated with a principal
building of at least one thousand (1,000) square feet of floor area.
c. The entire sales lot and off - street parking area is paved.
d. For motor vehicle sales activities, a minimum of three hundred
eighty (380) square feet of sales area per vehicle is provided.
e. A perimeter curb is provided around the sales /parking lot.
f. All lighting shall be hooded and so directed that the light source
is not visible from the public right -of -way or from an abutting
residence and shall be in compliance with Section 3, Subd. 4.F of
this Ordinance.
g.
Materials for sale shall be displayed in an orderly manner and
shall not constitute junk as defined by this Ordinance.
•
•
•
•
•
•
4. Temporary Commercial Stands/ Farmer's Markets
This would include anyone selling a product that is not grown on the site, or is not
accessory to the principal use occurring on the site. These would have to be temporary
events, or the `Open Sales Lot' information in number 4 would apply.
a. Licensing Issues
Selling fresh produce does not require a license. A license is needed for
anything other than fresh produce. Any vendor that sells processed food needs a
license from the Minnesota Department of Health, Anoka County, or the
Minnesota Department of Agriculture. Determining which body issues the
license is not intuitive.
b. Site Planning Issues
• Parking: The City currently requires all commercial businesses to have
off - street parking. If a parking lot is used for selling things, the off - street
parking is used up. The likely location of these types of uses will be
County Roads, and on- street parking would be limited to side streets and
may cause visibility issues.
• Waste removal: Waste removal would need to be addressed.
• Rest room facilities: This is an issue of providing facilities to serve the
vendors and employees more than to serve customers.
• Access and Circulation: Access to the site and circulation within the site
for emergency situations must be considered.
• Life /Safety Codes: There may be other issues regarding building or
electrical codes, such as the need for electrical power. Our Building
Dept. staff should be consulted.
• Zoning/Permitting: We would need to amend official controls to
accommodate this type of sales activity. At the minimum some sort of
permit should be required for temporary sales, while an organized,
regularly occurring farmer's market could require a conditional use
permit. A special event permit could be required through the City Code.
Staff is seeking any comments or direction from the Board prior to creating draft ordinance
language.

AGENDA ITEM 6.B.
STAFF ORIGINATOR: Paul Bengtson
P &Z MEETING DATE: June 9, 2010
TOPIC: Discussion of Building Materials
BACKGROUND
The Board had previously asked staff to review the allowable building materials and
architectural standards in the city. Section 3.Subdivison 4.B, which entitled `Building Type
and Construction', includes the architectural standards for the city. For the purpose of brevity
only subdivisions related to the topic are included.
Single Family
1. Single Family Dwellings. All single family detached dwellings in the R, R -X, R -1, R-
1X, R -EC, and R -2 Districts shall meet the following design criteria:
a. All structures shall have permanent concrete or treated wood foundations which
will anchor the structure, which comply with the State Building Code as adopted
in the State of Minnesota and which are solid for the complete circumference of
the house.
b. Sixty (60) percent of a residential structure shall have a minimum width or depth
of twenty (20) feet. Width measurement shall not take into account overhangs
or other projections. Such width requirement shall be in addition to the
minimum area per dwelling requirements established within this Ordinance.
c. Single family dwellings shall have at least a four /twelve (4/12) roof pitch and
shall be covered with shingles or tiles or a standing seam metal roof.
d. All single family structures must be built in conformance with Minnesota
Statute 327.31 to 327.35 of the State Building Code as adopted in the State of
Minnesota.
e. The exterior walls of all single family residences shall be similar in appearance
to normal wood or masonry residential construction. Any metal siding upon
single family residence structures shall have a vertical dimension no greater than
twelve (12) inches. Sheet metal siding shall not be permitted in such districts.
In addition to regulating single family stick built homes, these regulations also allow
manufactured homes in all residential district (as required by law) while still maintaining
similar appearance and materials to other homes within a neighborhood. Letters `c' and `e' are
the ones that might need to be reviewed and amended. One possibility is to require all
materials used to be `designed for residential use', and allow the zoning administrator to make
that determination. That would allow residents to appeal the decision through Section
2.Subdivision 4.
Multi Family
2. Two Family and Townhome Design and Construction Standards.
b. Unit Construction.
3) Minimum Overhang: In case of gable roof, a minimum eighteen (18)
inch roof overhang, soffit shall be required for all dwelling unit building
plans.
4) Exterior Building Finish: The exterior of townhome dwelling units shall
include a variation in building materials which are to be distributed
throughout the building facades and coordinated into the architectural
design of the structure to create an architecturally balanced appearance.
In addition, townhome dwelling structures shall comply with the
following requirements:
a) A minimum of twenty -five (25) percent of the combined area of
all building facades of a structure shall have an exterior finish of
brick, stucco and/or natural or artificial stone.
b) Except for brick, stucco, and/or natural or artificial stone, no
single building facade shall have more than seventy -five (75)
percent of one type of exterior finish.
c) For the purpose of this section, the area of the building facade
shall not include area devoted to windows, entrance doors, garage
doors, or roof areas.
3. Multiple Family Apartments Construction Standards:
a. The exterior of multiple family dwelling structures shall include a variation in
building materials which are to be distributed throughout the building facades
and coordinated into the architectural design of the structure to create an
architecturally balanced appearance. In addition, multiple family dwelling
structures shall comply with the following requirements:
1) A minimum of thirty -three (33) percent of the combined area of all
building exterior walls of a structure shall have an exterior finish of
brick, stucco, and /or natural or artificial stone.
2) For the purposes of this section, the area of the building facade shall not
include area devoted to windows, entrance doors, garage doors, or roof
areas.
The restrictions on Multi - Family are rather vague, but elevations are approved during the
Preliminary Plat process so the Planning and Zoning Board and City Council may make
comment. However, since it doesn't specifically prohibit any materials the city would have a
weak position to make demands unless the project is a Planned Unit Development. Similarly to
the Single Family requirements, it might be prudent to require materials to be designed for
residential construction.
•
•
•
Commercial, Industrial and Institutional
• 4. Commercial, Industrial, and Institutional. All buildings erected on land within
commercial, industrial and public and semi- public zoning districts, and all institutional
buildings (such as public, education, and religious buildings) in residential and rural
zoning districts shall conform with the following:
a. All sides of the principal and accessory structures are to have essentially the
same or a coordinated harmonious finish treatment pursuant to Section 3, Subd.
4.B of this Ordinance.
b. Exterior wall surfaces may be a combination of materials including brick,
stucco, EFIS (exterior finish insulation system), textured, colored or
decoratively finished pre -cast or poured -in -place concrete panel, textured
concrete masonry units, natural stone, manufactured stone, transparent, tinted or
low - reflective glass, or decorative metal cladding.
Stucco or EFIS shall constitute no more than thirty (30) percent of the primary,
front building elevation, and no more than sixty (60) percent of any side or rear
building elevation. Stucco or EFIS shall not extend closer than three (3) feet to
the ground plane.
Decorative metal cladding refers to decorative, metal cladding systems such as
copper, zinc, titanium, stainless steel and painted steel components fixed to the
outside of the primary wall system. Complete or partial buildings comprised of
structural metal wall panel systems that act as the primary wall system, or as a
• complete wall system such as pole barns or similar structures common to
agricultural or industrial storage uses are prohibited.
c. Buildings shall have a well - defined base, middle and top. The base should
appear visually distinct from the middle and top part (cornice) of the building
through the use of a change in building materials, color, window shape or size,
an intermediate cornice line, sign band, an awning, or similar techniques.
d. Earth tone colors of exterior materials shall be required. "Earth tone colors"
shall be defined as any various soft colors like those found in nature in soil,
vegetation, etc. Such colors are limited to various shades or tints of brown,
black, gray, tan, beige, brick red, soft green, soft blue, or white.
e. Ten (10) percent of the building facade may contain contrasting colors.
Contrasting colors shall be those colors not defined as earth tones.
f. All mechanical equipment, such as air handling units located anywhere on the
property, including rooftop equipment, shall be screened from view from
adjacent streets, public rights of way, and adjacent properties.
Where a site abuts a residential property, the location of air handling and other
equipment must take into account the potential for noise and other impacts on
the residential property.
The city updated the commercial /industrial /institutional section in 2005. This section has
functioned fairly well from staffs viewpoint. However it might be appropriate to add wood as
an acceptable material under letter `b'. Also, for letter `c' we may want to add a statement like
the Town Center Design and Development Guide has such as `Unless an exceptional quality of
design and materials is demonstrated' to allow some relief from the base - middle -top approach.
g.
