WHERE WE ARE NOW

Planning Linkages

TRANSPORTATION

Key IssuesRoad Design StandardsCongested Corridors & IntersectionsBicycle FacilitiesAlternative TransportationEmergency ManagementTransit Service ImprovementsInnovative Transportation Ideas

NEED FOR NEW INVESTMENT APPROACHNationally:

• Transportation funds lagging, at same time that transportation needs have increased

• Emphasis on asset management, coupled with less revenue, has serious implications on revenue availability for new infrastructure

• Multimodal capital investments must be identified in transparent processes that are performance-driven and outcome-based

NEED FOR NEW INVESTMENT APPROACH

In Planning Area:• Shift to multimodal investment

has been limited in its geographic extent

• Large areas throughout region remain dangerous to pedestrians and cyclists and inaccessible to transit users

TRANSPORTATION/ LAND USE INTEGRATION• Evaluate land use impacts related to transportation

choices/investments• Update Comprehensive Plan to reflect the Regional

Transportation Plan• Create new land use and transportation strategies

to support community goals.• Increase density and encourage transit oriented

mixed use developments

TRANSPORTATION/ LAND USE INTEGRATION

NATURAL RESOURCES

Purpose :

• Inventory and analysis of natural resources

• Prioritize areas for protection

• Target development to areas most appropriate

• Expand public’s knowledge of environmental issues in Hamilton County

• Inform the development of goals regarding conservation, protection, preservation, or restoration of natural resources

FLOOD PLAINSFunctions and Benefits:

• Infiltrates stormwater

• Regulates flow

• Recharges groundwater

• Buffers sensitive riparian resources

• Filters water

• Mitigates erosion

• Stores sediment and nutrients

• Provides habitat and preserves biodiversity

• Provide scenic beauty

STEEP SLOPESDevelopment related disturbance can:

• Increase erosion, slope instability, and safety concerns

• Increase quantity of runoff and reduced water quality

• Result in loss of habitat and biodiversity

• Result in loss of scenic beauty and community character

In 2013, the City spent $1.8 million in repairs due to slope instability issues.

Public Works asked for an annual $2 million dollar budget to address slope instability issues in 2013.

ADDITIONAL ANALYSIS NEEDED

• Intact Forests• Farmlands and Prime Agricultural Soils• Biodiversity• Where do sensitive resources overlap?• What areas should be protected? • How do we minimize the unintended impacts

of development ?

Loss of Open Space

Fragmentation and Habitat Loss

Increased Runoff Increased Pollution

Communities can grow while protecting water and other natural resources
