AGENDA ITEM V. A
STAFF ORIGINATOR: Jeff Smyser
P & Z MEETING DATE: March 8, 2000
TOPIC: Preliminary Plat, Bluebill Ponds
BACKGROUND
The applicant, Heritage Development, has submitted an application for a preliminary plat.
The site is on the south side of Main St. across from Wood Duck Trail and Blue Bill
Lane. The original application came before P & Z in October 1999. The project has
been continued since then for various design reasons.
The City received this revised plat application December 13. State statutes allow 120
days for the City to make a decision on a preliminary plat application. In order for the
City Council to meet this statutory deadline, the Council must act at its March 27
meeting. Therefore, the application was put on the March P & Z agenda.
• This report is based on the most current submittal consisting of the following:
•
Preliminary Plat 12/10/99 submitted 12/13/99
Preliminary Utility Plan 12/7/99 submitted 12/13/99
Preliminary Grading Plan 12/7/99 submitted 12/13/99
Hydrology Map 12/7/99 submitted 12/13/99
The site is completely within the existing MUSA. Land use and zoning for the site and
surrounding land are listed in the following table.
The site includes 3 5.3 5 acres.
The proposed plat would create 77 single family lots.

Wetlands cover 2.15 acres.
Gross density would be 2.18 units per acre.
Net density, subtracting the wetlands, would be 2.32 units per acre.
ANALYSIS
Lots, Blocks
The submitted information indicates that lot areas shown on the plat do not include
wetlands or ponds. All lot areas would then comply with the required minimum area of
10,800 sf of buildable land per lot in the R -1 zone. Most lots meet the minimum width
and depth requirements of 80 ft. and 135 ft., respectively.
However, we require a lot depth of 145 ft. on double - frontage lots. The lots in Block 1,
along Main St., are double - frontage lots. Lots 5, 6, and 7 do not meet this requirement.
Lot depth is measured as "the shortest horizontal distance between the front lot line and
the rear lot line measured from a ninety (90) degree angle from the street right -of -way
within the lot boundaries."
Because of the roadway issues, described below, the layout of the plat will have to be
altered, which will result in a reduction in the number of lots.
Parks and Trails
Originally, staff envisioned some park land in the southeast corner of the site. This
would be near the park in the Highland Meadows West plat. The two sites touch at the
corners only, so the entire park would be oddly configured. The missing connecting
piece would have to be filled in when the land to the east of Bluebill Ponds develops. We
have no indication that this will occur in the foreseeable future, so the missing piece is
only speculative.
The greatest impediment to designing park land into this site is the road on the south edge
of the plat. This road was requested by the majority of the residents on the south side of
the road, in Mar Don Acres. The future extension of this will separate the Bluebill Ponds
site from the Highland Meadows West park site.
The park dedication requirement is about 3.3 acres, or the equivalent in cash. We
estimate that the cash dedication would be approximately $81,000.
The 1992 trail plan envisions a trail crossing this site from east to west to facilitate a.
future connection between the park and 4th Ave. A trail within a road right of way could
provide for a trail across this plat. However, a connection to 4th Ave. will be difficult to
create unless land to the west develops. Currently, that land is zoned Rural. The draft
comprehensive plan shows some additional land in a growth area, but not all the way to
4th Ave.

The Park Board met to review this plat on March 6. Staff will have the Park Board's
review for the March 8th P & Z meeting.
Stormwater Management and Wetlands
The City and the Rice Creek Watershed District are promoting infiltration and volume -
reducing techniques. The proposed grading plan does not incorporate such techniques.
The stormwater management should be redesigned.
The wetlands will be covered by a drainage easement on the final plat according to
standard policy. We have no information from the Watershed District regarding its
review of the project. The City typically includes final Watershed approval as a
condition of approval, but staff always requires an indication of pending Watershed
approval before we recommend approval of the project.
Utilities
The applicant has assumed that sewer and water service will come from Main St. This is
not necessarily the case. It is possible that utilities should come through the Highland
Meadows West development and 79th St. We will need to prepare a feasibility study to
determine how this development and nearby areas will best be served. It is City policy
that the benefiting property owner bear the cost of such a study.
We have received a petition for public improvements that would include extending 'sewer
and water to the site. This petition has not yet been formally considered by the City
Council.
Transportation, Roads, Access, Circulation
Main St. Access: The major issue at this time is access to Main St. (CSAH 14).
Anoka County recently completed an access management study. Eventually, Main St.
probably will have a median separating eastbound and westbound traffic. Wood Duck
Trail is the designated location for a full access intersection. Bluebill Lane will be a
limited access intersection. This means that Bluebill will be a right - in/right -out only
intersection. The Bluebill Ponds development, with 77 lots, will be ill- served with such a
limited access intersection.
In addition, the City should be looking to provide circulation in the area. Ultimately,
there will be 150+ dwelling units in Highland Meadows West, and 70+ in Bluebill Ponds.
A full access intersection on Main St. is the appropriate connection, and Wood Duck
Trail is the appropriate location for it. The new roads through these plats will be very
curvy. They will not be very good for a shortcut route between Main St. and Lake Drive.
Rather, the new roads will provide circulation through these developments and access for
the residents.

The problem with the Main St. access is that the extension of Wood Duck Tr. south of
Main St. would cross the property of the House of Praise church. The developer and the
church are negotiating a land trade that would allow the Wood Duck extension. The
church would best be served with a full intersection rather than partial access to Main St.
The developer would have better access for the new development. It will be safer for
churchgoers to have access on the new extended Wood Duck Tr. than to access Main St.
directly. The City will benefit from the improved safety because of the better access
management, and from improved circulation in that area of the City. The goal is a result
that benefits the developer, the church, and the City.
As proposed, the Bluebill Ponds plat is designed to have Bluebill Lane as its immediate
access. A Wood Duck access could be created in the future. City staff believes the
present proposal should be redesigned after the negotiations with the church are settled.
The redesign should address the public safety concerns of access to Main St. and create
the Wood Duck intersection.
The landowners also have submitted a petition for public street improvements, which
would include road access to Main St. This petition will require a decision by the City as
to whether the City will undertake an eminent domain action to take property from the
House of Praise Church for the Wood Duck Trail extension.
Road Along Mar Don Acres: Mar Don Acres is immediately south of the Bluebill
Ponds site. When Mar Don Acres was platted in 1978, the northern 30 feet was included
in an easement. This 30 feet was intended to be the southern half of a right of way for a
road. The other half would be supplied when the land to the north (the Bluebill Ponds
site) was developed. --
Following the first review of Bluebill Ponds by P & Z in October 1999, several residents
of Mar Don Acres informed us that they wanted the road built along the south border of
Bluebill Ponds. They want the option of subdividing their lots. Staff held a
neighborhood meeting on November 9, 1999 to discuss this issue. Residents along the
alignment of the desired road were invited, including those in Mar Don Acres, Sherwood
Green, and unplatted properties to the north.
Based on this meeting and follow -up calls to residents who were not at the meeting, staff
found that six of eight property owners in Mar Don Acres wanted the road. Residents in
Sherwood Green and lots to the west of BlueBill Ponds did not want the road. Staff
directed the developer to include a road on the plat. The submitted plat shows the road,
but it starts on Lot 3 of Mar Don Acres. The west end should extend to halfway across
Lot 2 Mar Don Acres.

ENVIRONMENTAL BOARD RECOMMENDATIONS
The Environmental Board considered the original application on September 29. That
Board recommends a 50 ft. buffer around the forest on the east edge of the site,
infiltration and overland runoff design where possible, open spaces to be incorporated
into the design, use of native vegetation, a buffer around wetlands, and deep tilling -of
topsoil. The Environmental Board's recommendations are attached.
OPTIONS
1. Continue the public hearing to allow the applicant to redesign the plat and supply
additional information to address the issues discussed in this report. This will require
an agreement from the applicant to continue the plat review period.
2. Deny the preliminary plat as submitted if no extension granted.
RECOMMENDATION
Option 1. If no extension is granted, Option 2.

RE: Environmental Board Recommendations
CC: Environmental Board Members
The following is the Environmental Board recommendations for the projects that were on
the agenda:
Athletic Complex
The Environmental Board recommends that the Athletic Complex be implemented in a
manner that will not only satisfy the recreation needs _of the city, but will also
demonstrate good environmental stewardship. This is a superb opportunity for the city to
create a complex that works to enhance, rather than degrade, the environment. The
Environmental Board would like to work closely with city staff to make this park a
demonstration of the environmentally aware nature of our city.
Blue Bill Ponds
The Environmental Board recommends the following:
1. The design of the development should be modified so as to create a 50 -foot buffer
along the eastern edge of the property to protect the significant stand of hardwoods on
the adjacent property to the east.
2. Ponds should be designed to infiltrate water on site as much as possible.
3. The city permit flexibility in R -1 zoning standards on street width, lot size, street
setback, frontage, etc... to permit preservation on larger tracts of open space without
changing density.
4. Attempts should be made to create an overland storm water treatment train for surface
runoff leaving the site.
5. When restoring vegetation to the site, the Environmental Board recommends the use
of native materials, or other plants that require little irrigation or nutrient addition.
6. Property owners be informed that 8 - 10 inches deep tilling of topsoil prior w sod or
seeding will improve turf performance.
7. The creation of a buffer of native vegetation around natural and created wetlands.
Highland Meadows Re -plat
1. Attempt to create a buffer to preserve stand of oaks on west side of property.
2. City permit flexibility in R -1 zoning standards on street width, lot size, setbacks,
frontage...etc to permit preservation of larger tracts of open space without changing
density.
3. Project design should attempt to maximize infiltration of storm water on the site and
reduce runoff into lakes and naturally occurring wetlands. When runoff into water
bodies is unavoidable, storm water should be directed over a vegetated surface via
broad swales. The design should attempt to maximize the surface area over which the
water tlows. The total linear distance of this storm water treatment train should be at
least 100 feet between the storm water detention pond and the destination (ditch, lake,
wetland).
4. Before spreading topsoil, the board recommends tilling the soil 8" to 10" deep to
maximize the successful establishment of Landscaping and minimization of surface
runoff due to soil compaction during construction.
5. When restoring vegetation to the site, we recommend use of native materials or other
plants that require little irrigation or nutrient addition. Use of exotic, invasive species
is strongly discouraged. (Eg. European buckthorn, Norway maple) See City
Environmental Coordinator for lists of recommended and non - recommended species.

AGENDA ITEM VI. A
STAFF ORIGINATOR: Jeff Smyser
P & Z MEETING DATE: March 8, 2000
TOPIC: DISCUSSION ITEM
Draft Town Center Standards
I've attached the last part of the draft. Much of these chapters will require City staff
input regarding lighting, street furniture, etc. The City Engineer is conducting
discussions with public works staff on other pieces as well.
I suggest that our discussion at the March 8 P & Z meeting include the following:
• review of past discussions, questions, clarifications
• general discussion on signage (as specific as you feel is appropriate at this time)
• discussion of questions on Chapter 5 and, such as it is, Chapter 6
I may have additional information to share by the time of the meeting.
Please feel free to call with any questions at (651)982 -2425.
CHAPTER 5.
PUBLIC IMPROVEMENT
STANDARDS
5.1 STREETS
Street Hierarchy, Context, and Design
The street network for the Lino Lakes Town Center provides five points of entry to the site from
Lake Drive. Anetwork of required streets, enhanced by pedestrian walkways through parking lots
and along open spaces, provides connections between the Mixed -Use, Residential, and other Dis-
tricts of the Town Center. There is potential for a pedestrian overcrossing at Interstate 35W, linking
the two sides of the Town Center.
Streets in the Town Center provide for the comfort of pedestrians and the needs of the automobile.
Unlike in traditional suburban-style development, the streets in the Mixed -Use Districts are lined
with buildings and landscaped parks or open space, rather than parking lots, creating a pleasant
environment for walking and an interesting route for drivers. Parking is set behind buildings,
away from the street. The narrow roadway widths discourage fast automobile speeds, while still
allowing automobile access throughout the site.
All streets have on -street parking, which helps provide a "buffer" between the traffic on the street
and the pedestrians on the sidewalk. Street trees are required on both sides of all street rights -of-
way, spaced at no more than 30 foot apart. Certain streets have trees planted in between parking
spaces, and certain streets have swales to help control and filter stormwater runoff.
Allowable Street Sections
Figure 5, in Chapter 2, shows the location of the Required Streets in the Town Center. The Required
Streets Plan, Figure 6, specifies the type of street section associated with each Required Street, and
also shows the location of a suggested, complementary network of streets to serve the remainder
of the Town Center, including the Residential Districts.
The alignments of Required Streets are fixed. The alignments of non - required streets, including all
residential streets, are flexible, but should enhance views and minimize grading requirements. Site
planning should recognize the role that street alignment and topography contribute to visual promi-
nence. High points on the land and vistas along common routes provide unique opportunities to
site important buildings and places, such as civic institutions or landscaped plazas. Doing so will
add recognizable landmarks that can make the Town Center a memorable place.
All streets in the Town Center, including Required Streets and other streets, must be one of the
specified street sections described in this chapter, including lane and sidewalk widths, location
and type of street trees and on -street parking. The street sections are broadly classified into Com-
mercial Streets and Residential Streets. There are eight street sections:

Traffic Calming Measures. A combination of techniques can be used in residential areas or
TOD cores to effectively "tame" traffic. Drainage, snow removal, and storage must be considered
in the design and maintenance of these features.
62
Street Trees
The Town Center should be landscaped with a palette of street trees and groundscaping keyed to
the eight types of streets, to help establish the hierarchy of streets and provide a cohesive theme for
the Town Center. The largest trees should be located on the busier Commercial Streets.
Spacing. Street trees should be planted on both sides of streets and spaced no more than 30 feet
apart.
Species. Each type of street should have one species of street tree for the sidewalk planting area,
with an additional street tree type for any in -street parking space trees or linear parks or planted
medians.
Plant Materials. In Commercial areas, sidewalks are likely to be all hardscape between street trees.
However, in Residential Districts, a common palette of groundscaping such as turf and low plants
is recommended for the sidewalk area between paving and roadway. A judicious selection of plants
includes consideration of site - specific conditions such as shade, wind, moisture, and soils.
More on plant materials.
Street Trees. Street trees should be spaced no
more than 30 feet on center.

Street Lights
Light Standards
Streets must be lit with light standards (fixtures and poles) with a consistent appearance through-
out the Town Center. Specific brand of standards (manufactured by ) should be used, or a stan-
dard of equivalent form and level of detail (see the Appendix). Light bollards are also encouraged
in areas with high pedestrian activity levels; see the discussion on bollards in "On -Site Lighting" in
Chapter 3.
Fixtures. Double -head fixtures are recommended along streets where both sidewalks and travel
lanes must be illuminated, and should be attached to poles with a contemporary arm such as the
semi - circular arms depicted. Single -head fixtures are acceptable in other areas.
Poles. Metal poles should be used and should be round and tapered. Poles should have a highly
durable, low- luster, dark green enamel finish.
Bases. Along Commercial Streets, a concrete block base should be used for free - standing lamp stan-
dards, with an appearance that is consistent with Landscaped Frontage walls. The concrete block
base should be approximately 24 inches high. Where a masonry base is used, the connection be-
tween the pole and this concrete block base should be accompanied with an ornate base cover.
Banners. To add color and announce seasonal events, banner arms may be mounted on light stan-
dards along streets and in parks and plazas. The bottom edge of banners should be at least 9 feet
above grade. To avoid damage from tall trucks, banners should not be located within one foot of
the edge of the curb as projected vertically. Banners should not exceed a width of 2 feet. For light
standards up to 16 feet in height, banners should not exceed 3 feet in length, with one additional
foot of banner length permitted for every additional foot in pole height, up to a 6 -foot maximum
length.
Permitted Heights
The height of light standards should correspond to the activities they illuminate:
AIong Pedestrian Streets. Light standards in environments where pedestrians are the primary fo-
cus (e.g. required streets in the Mixed -Use District and pedestrian walkways) should be lower in
height to create an environment that is more human in scale.
Along Primarily Automobile - Oriented Streets. Light standards along major streets must relate to
both vehicles and pedestrians at the edge of street, but may be taller in street medians.
Maximum lamp heights and corresponding locations are shown in the diagram.
Placement
To the extent feasible, pairs of light standards should be placed symmetrically along opposite sides
of the street.
Retrofit of Existing Standards
Where Lake Drive is expected to maintain its existing cross - section in the foreseeable future, the
existing cobra head fixtures are likely to be maintained. To help establish a consistent identity along
the length of Lake Drive, it is recommended that banners be mounted on light standards.

Street Paving & Furnish-
ings
Intent
Paving, plants and site furnishings will help set
the character of the Town Center. These features
should be consistent with the following recom-
mendations, whether in streets, in parks or pla-
zas, or as on -site landscaping. Recommended
materials and finishes include brick, limestone or
limestone veneer, white - painted wood, and forest
green- painted metal.
65

General Standards
Paving. Special pavers are recommended in parks, plazas, and in crosswalks in required streets.
Pavers should be durable and of brick, stone, or other materials appropriate to the traditional style
of the region. Interlocking pavers should be used to avoid uneven edges. Paver patterns should be
simple and should be reviewed to ensure quality and consistency.
Tree Grates. Tree grates should occur along sidewalks and in plazas where a continuous walking
surface is needed. A distinctive shape that combines a circle and square should be used, where
possible, with the square end adjacent to paving edges or curbs. Narrow openings should radiate
from the center. Tree openings should be expandable. Grate sizes should be a minimum of 4 feet in
diameter. Grates should be painted with multiple coats of low- luster, forest green enamel.
Tree Guards. Tree guards should extend vertically from tree gates to protect trees in highly active
areas. To relate to other site furnishings, tree guard bars should be narrow, vertical, and black in
color. They should be attached to the tree grate. Welds should not be visible. Guards should be
painted with multiple coats of low- luster, forest green enamel for durability. Tree guards should be
about four feet in height with openings varying in diameter according to tree species.
Kiosks. Kiosks serve as information booths and /or shelter for small vendors. Kiosk design should
be consistent with the architectural style of surrounding buildings and any nearby Landscaped
Frontages.
Newspaper Racks. Newspaper racks should occur around major pedestrian gathering areas. The
design should consolidate all vending boxes into one rack. Rack construction should use masonry
elements or metal that compliments other site furnishings in the area, or the architecture of adjacent
buildings. The rack should be attractive on all sides and properly anchored.
Bicycle Racks. Bicycle racks should be selected that are durable and visually subdued. Based on
their performance, "loop racks" and "ribbon bars" are recommended, and should be sized accord-
ing to parking requirements. A durable forest green powder - coating is recommended. The Appen-
dix includes examples of appropriate bicyde parking structures.
Trash Receptacles. Throughout the Town Center, trash receptacles should be provided. Receptacles
should have vertical metal bars and be painted forest green to match other recommended features.
To avoid overflow, receptacles should be sized to be at least a 30 gallon capacity, especially in com-
mercial areas, and should be properly anchored. Multiple coats of a powder - coating or comparable
finish is recommended for durability.
Planters. Planters should be simple in form. Round and square types are recommended. Material
should consist of cast stone or precast concrete. Planters should be at least three feet in diameter.
Where planters are called for, group various sizes in clusters to enrich streetscapes and plazas.
Bollards. Pedestrian plazas should be designed with the consistent use of pavers and without curb-
ing. Bollards should be placed to restrict vehicle access at the perimeter of plazas, where pedestri-
ans and vehicles cross paths. Collapsible bollards should be used where service vehides or emer-
gency vehicles may need to pass. Design of bollards should have a classic style, and consist of iron
or aluminum to be painted with multiple coats of low- luster, forest green enamel. Bollards may be
fitted with lighting for dramatic or intimate settings. Bollards should be at least 29 inches in height.
Seating. Low walls should be integrated into the design of parks and plazas for seating. Wooden
benches are appropriate within parks and plazas in intimate settings or where flexibility in the
location of seating is desired. Seating may also be incorporated into the design of Landscaped
Frontages.
66
Wood benches should use smoothly finished, exterior -grade members. Wood members should be
supported by cast iron or aluminum ends with a low- luster, forest green enamel finish. Benches
should range from four to eight feet long. Intermediate arms are recommended for longer benches.

Street Furnishings. A unified palette of materials, colors, and finishes in street furnishings such as these
will help tie together the different districts of the Town Center. These furnishings should also be used on
private plazas, parks, and commons. Acceptable materials include white - painted wood ( ?), black or dark
green iron, limestone, and brick.

Gateway Features
There are four gateways to the project, two on each side of Interstate 35W, as shown in Figure 5, the
Regulating Plan. Gateways include signage that is civic in emphasis, marking the Lino Lakes Town
Center. Gateways may be freestanding "monuments" or monuments integrated with Landscaped Frontage

Gateway and Tower at Library. The library south of I -35W sits at one of the most prominent gateways
into the Town Center. A "gateway" element should be integrated with the trellis, fence, wall, or hedge that
form the Landscaped Frontage along the entry road. The library building should include a tower element.

5.2 OPEN SPACE DISTRICT STANDARDS
The Open Space Districts have been designated to protect valuable natural features including hill-
sides, creeks, significant woodlands and heritage trees.
Permitted Uses.
Parks. In Parks, minor structures such as bandstands, gazebos, storage sheds, and food concession
stands are permitted, provided that all structures occupy no more than 10 percent of each park area.
Furthermore, each structure may not exceed 500 square feet floor area. Trails, pathways, and children's
play structures are also permitted in Parks.
Buildings adjacent to Parks must face the Park, rather than backing or siding onto it.
Natural Resource Areas. No structures or paved areas are allowed in Natural Resource Areas ex-
cept for trails designed according to the specifications here.
Buildings adjacent to Natural Resource Areas must face the Resource Area, rather than backing or
siding onto it.

5.3. PUBLIC INFRASTRUCTURE
Stormwater & Urban Runoff
Comprehensive Management Plan. The City shall develop a comprehensive stormwater manage-
ment plan. The management plan shall delineate requirements on private lands and detail public
improvements. The following principles should guide the development of the plan.
Decentralize Retention. Stormwater retained "close to the source" reduces the need for large -scale
improvements that are expensive and inconsistent with the project's emphasis on ecology. Utilize
landscaped swales, wetlands, park and plaza features, or other site amenities to minimize piped
drainage and facilitate percolation.
Naturalize Retention. Generally, retention areas should have a natural profile and wetland plants
to filter pollutants (e.g. motor oil and fertilizers) and slow run -off. Naturalized solutions are espe-
cially critical along the edge of natural areas to protect sensitive habitats.
Permeable Paving. Permeable ground surfaces allow the exchange of water and air to occur, re-
charging aquifers and aerating soils. Such surfaces should be required ... or gain a density or FAR bonus.
Large areas of paving such as parking lots should use combinations of materials according to the
need for durability: areas of lower use call for grasscrete or gravel, while areas of high use should
have permeable concrete or asphalt. Plazas should be paved with sand- packed pavers, particularly
in low -lying areas.
Grading. Site designers should consider ways to minimize grading when locating streets and build-
ings. When areas with slopes must be graded, " landform" grading techniques should be used and
slopes exceeding 1:3 should be avoided. Rounded forms that use concave and convex shapes also
help conceal cuts by presenting a more "natural" look. Varied slopes disperse drainage flows, al-
lowing more percolation and reducing the potential for erosion.

Grading. A "naturalized" landform (right) is preferred over straight, linear slopes (left). Naturalized
landforms also reduce the likelihood of erosion.

Integrated Site Planning. Application of stormwater management
techniques early in site planning can suggest street and pathway
alignment, as well as optimum locations for swales to help filter and
detain runoff. In this way, solutions generate cost - effective development
that recognizes land forms and integrates nature in pleasing ways.
Information Infrastructure
Maximize Internet Capabilities. The City shall pursue the extension of fiber -optic cables to the site.
Digital Subscriber Lines (DSL) ? ? ?? are presently extended to the Middle School, and may be
extended to the Town Center for public uses — such as the proposed library and community recre-
ation building (e.g the YMCA). The Town Center should contain a menu of internet- related facili-
ties that serve the larger community, and make it a desirable to live and work.
Library Workstations. The reading rooms of the future will rely increasingly on computers, moni-
tors and modems. The new library should be a preeminent place for information technologies.
Teleconference Facilities. Teleconference facilities should be created within the library or elsewhere.
Teleconference facilities can serve cultural, educational and business needs, and may be an impor-
tant factor in a resident's and business' decision to locate in the Town Center.
Digital community "billboards" and kiosks. Community events and information might be dis-
played on large "billboards" or kiosks that face the Village Green, the lobbies in the library and City
Hall, or other locations. Bold and dynamic images on the billboard may contribute to the creation
of an exciting Town Center.
Regional Park Interpretive Center. Internet capabilities may enhance the _ Regional Park as an
educational resource. Scholars and others can explore the park, but then also conduct research and
conferences via the intemet. The internet may also facilitate the creation of exhibits and displays. A
digital interpretive center could house these facilities where the east -west "main street" meets the
park, further enhancing the Town Center as a unique destination.
Live -Work and Residential Access. The availability of Digital Subscriber Lines (DSL) may be an
important factor in attracting residents who are interested in living and conducting business in the
Town Center. At -home businesses will help enhance the Town Center as a destination and active
place.
Business Access. Information infrastructure should be made available to businesses throughout the
Town Center and in potential business locations west of Lake Drive.

CHAPTER 6.
IMPLEMENTATION
6.1. DISTRICT BOUNDARY CHANGES
Delineation of Residential Districts.
The Illustrative and Land Use Plans call for three Residential Districts within the Town Center.
Standards in this chapter pertain to residential uses in the Residential Districts. Residential uses are
also permitted within Mixed -Use Districts, where Mixed Use Standards apply.
The extent of the Residential Districts may be modified based on detailed surveys of natural re-
sources, and subject to the review and approval of the Director of Planning.
Redesignation of Residential Districts.
Landowners may apply to redesignate all or portion of a Residential District as a Mixed -Use Dis-
trict, provided that:
• Landowners provide within this and /or other Mixed -Use District a number of residential units
consistent with the minimum and maximum densities that would have been applied to the
District redesignated (see Table 6 below),
• The open space provided is equivalent to that originally required (see the standards for Pub-
licly- Accessible Commons below), and
• The area originally designated as a Residential District be left undeveloped until the required
residential units are constructed within the Mixed -Use Districts, thereby ensuring the inclusion
of residential uses within the Town Center.
