▪ Rural history

▪ Concern for environment

▪ Managed growth density

▪ Responsible commercial

development


GENERAL CONSIDERATIONS

DESIGN GUIDELINES FOR SUSTAINABILITY & DEVELOPMENT

HOMER GLEN’S CORE VALUES

Source: New Resident Welcome Booklet

4

Sustainability means meeting the

needs of the present without

compromising the ability of future

generations to meet their needs.Source: Brundtland Report, Our Common Future, 1987




WHAT IS SUSTAINABILITY?

5

▪ Ensure Village provides standards and policies

that support implementation of the Comp Plan(FUTURE LAND USE PLAN; SUBAREA DEVELOPMENT CONCEPTS)

▪ Guide mixed-use/planned unit developments

▪ Serve as a tangible reflection of the quality of life

and livability in Homer Glen




WHY ADDRESS DESIGN GUIDELINES IN COMPREHENSIVE PLAN?

6

▪ Current land use:Single-Family Residential 47.2%Multi-Family Residential 3.6%Commercial 3.0%

▪ Demographics:

▪ New residential subdivisions approved in past 10 years:The Square at Goodings Grove (2018)




WHERE IS HOMER GLEN TODAY?

HOMER GLEN WILL COUNTY

Median Age, 2017 42.3 33.3

Median Household Income, 2017 $97,254 $80,782

Median Home Value, 2017 $304,400 $216,400

Population Change, Age 65+, 2010-2017 47.7% 28.1%

7

▪ School district enrollment:Homer CCSD 33C is experiencing a “flattening” trend due to a lack of major residential developments on the horizon

o The minimal increase (less than 1%) that occurred in recent years was mostly due to the Sagebrook development in Lockport

o There is a concern if this “flattening” trend would continue

▪ Greater housing and transportation options

▪ Compact development with smaller lots:: IN TARGETED SUB-AREAS

▪ Housing design:: HEIGHT; FORM; STYLES AUTHENTIC TO HOMER GLEN – CRAFTSMAN STYLE; MODERN FARMHOUSES; LEED CERTIFICATIONS

▪ Walkability-related features:: BUILDING FACADES ALONG THE SIDEWALKS

▪ Reduced water consumption

▪ Greater energy efficiency:: NET-ZERO ENERGY CAPABLE

▪ Efficient and natural stormwater management

▪ Preservation and expansion of open spaces and natural areas:: OPEN LANDS PROGRAM




WHY SUPPORT SUSTAINABLE DEVELOPMENT?

CONSERVATION DESIGN9

FOCUS: Conservation Subdivision Regulations


DISCUSSION TOPICS #1

▪ Assess original purpose and potential changes

▪ Evaluate how conservation subdivision standards advance sustainability and development goals

▪ Review better ways to advance sustainability and still promote growth




WHAT IS THE CURRENT CONSERVATION DESIGN ORDINANCE?




WHEN IS THE CURRENT CODE REQUIRED?

▪ Lot sizes: 12,000 sq ft (R-3A) up to 40,000 sq ft (R-1)

▪ Residential clusters: At least 5 units, but no more than 20 units

▪ Minimum 30 ft landscaping buffer around development exterior

▪ Percent open space: 20% (R-3A, R-6A) to 50% (R-2, R-2A)

▪ Not less than 90% lot abutting to open space




DEFINITIONS: NET DENSITY & NET ACREAGE




CONSIDERATIONS:

▪ Potential hindrance to development and new

residential subdivisions

▪ Difficulty to apply standards to deep and narrow lots

▪ Example: South Pointe Development [SEE NEXT SLIDE]

:: 40-acre deed-restricted conservation area (unique feature)

▪ Have these CD Ordinance goals been achieved?:: Preservation of open space: Over 20% preserved

:: Unable to design 90% of the lots abutting open space lots




South Pointe (M/I Homes) | October 2018




POLICY CONSIDERATIONS:

▪ Alternative approaches to acquire prime open

space rather than requiring new development

proposals to trigger conservation

▪ Encourage sustainability-minded neighborhoods:: Compact development :: Walkability

:: Reduced water consumption :: Greater energy efficiency

:: Efficient and natural stormwater management

:: Open space preservation




POLICY CONSIDERATIONS:

▪ Methods to protect open spaces::: Conservation easements

:: Permanent restrictive covenants

:: HOA/developer-submitted plan for open space management

▪ Partner with sustainable developments

and offer incentives:: Density bonuses

:: Fee reductions




POLICY CONSIDERATIONS: ORLAND RIDGE DEVELOPMENT

:: Mixed use :: 104 attached ranch units :: 45,000+ sf commercial

:: 57.7 acres :: 190 townhome units :: 10.3 acres preserved wetland




CONSIDERATIONS:

▪ Allowance for different housing types, particularly

in and near commercial corridors via PUD:: Housing Market Analysis (underway)

:: Need for full life-cycle housing

:: Max Net Density: Up to 9 du/acre for multi-family and mixed use

(The Square at Goodings Grove was approved for 8.9 du/acre)

▪ Review current zoning/housing typology:: Floating zones for cottage/courtyard housing (Evlyn’s Gate North)

:: Potential rezonings for new R-4 and R-6 (remove grandfathering)

:: R-4: 12,500 sq ft lots (current code)

(what is recommended based on other community data?)

:: R-6: Multi-family residential uses

:: Merge some of the single-family residential zoning districts (10 current districts)

TREE PRESERVATION19

FOCUS: Tree Preservation Ordinance



▪ Review Environment

Committee’s recommended

amendments to ordinance

▪ Evaluate potential impact of

amendments on Village’s

commercial corridors and

planning subareas

TREE PRESERVATION20



RECOMMENDATIONS FROM ENVIRONMENT COMMITTEE:

▪ Lower threshold for preservation on individual lots

▪ Effectiveness of developer incentives

▪ Prioritization of trees preservation areas:: Alternative to application to all lots

:: Potential for overlay zone

▪ Commitment as a Tree City USA community

LANDSCAPING21

FOCUS: Landscaping Standards



▪ Minimal landscaping standards at present

▪ Potential for traditional Landscaping Code to

advance Village’s expectations for high quality

development

LANDSCAPING22

CONSIDERATIONS:



▪ Buffering between different land uses

▪ Parking lot landscaping

▪ Potential incentives for landscaping

▪ Corridor landscaping, not in ROW

▪ Foundation landscaping

▪ Integration with other development standards(e.g., Tree preservation and conservation design as part of PD process)

▪ Stormwater management considerations

▪ Interplay between landscaping and signs

▪ Trigger for PUD review process(Current: Sites over 50,000 sq ft)

STREETSCAPE23

FOCUS: Board feedback on streetscape design


DISCUSSION TOPIC #4

▪ Review current Streetscape standards [SECTION 138.3A]

▪ Review Community Branding project

▪ Board-approved FY20 budget placeholder for

gateways and signage

STREETSCAPE24

Gateway & Wayfinding Signs Project


DISCUSSION TOPIC #4

▪ High quality sign design template integrating Homer Glen brand

▪ High quality and weather-resistant materials
