Integrating LID Into the Development Planning Process

We Have a Responsibility!

To meet Water Quality Protection Under 62-40 F.A.C.

Provide Flood Protection

Address Stormwater Management in Comprehensive Plans / Land Development Regulations

We Have a Problem!

We are not meeting our NPDES requirements and water quality standards,

water supplies are decreasing while demands are increasing, and we still need

to manage for flooding!!

So How Do We Fix It?

The Solution

Presumptive Criteria for Water Quality

Demonstrate the system provides water quality treatment ( retention,

underdrain, exfiltration, wet detention, swales or dry detention) in

accordance with 40C-42.026 F.A.C.

Alternative Treatment Systems

Affirmatively show that system design will provide equivalent

treatment

Managing Stormwater

Conventional Planning & Design

Low Impact Development

Managing Stormwater

Conventional Planning & Design LID Site Design

Style of suburban development over last 50 years

Generally involves larger lots Clearing and grading of

significant portions of a site Wider streets and larger cul-

de-sacs Enclosed drainage systems

for stormwater conveyance Large detention ponds

Conservation of natural hydrology, trees, and vegetation

Minimized impervious surfaces

Dispersal of stormwater runoff

Conservation of stream & wetland buffers

Ecological landscaping

Managing Stormwater

The Problem The Solution Loss of natural land

or open space

Depleted drinking water supply

Reduced quantity and quality of water resources

Increased infrastructure costs & maintenance

Less land clearing and grading costs

Reduced infrastructure costs

Protection of water quality

Reduced stormwater runoff

Who Are The Players?

Property Owners Developers Local Government Water Management Districts Educators & Researchers

What Is Local Government’s Role? All development must be consistent

with the comprehensive plan and comply with the Land Development Regulations

Local government should promote & support the most economical and sustainable development applications

Local government should coordinate with WMDs

What Tools Does Local Government Have?

Comprehensive Plan Land Development Regulations Design Guidelines Development Review Process Monitoring / Maintenance

Comprehensive Plan

Future Land Use Element Authorize / Incentivize Cluster

Development Recognize LID as Alternative to

Conventional Development Provide Incentives (Density) for LID

Comprehensive Plan

Stormwater Management Sub Element Define LID Recognize LID as Preferred Alternative

New Development Retrofit (deficiencies)

Establish Levels of Service Establish Maintenance Responsibilities

Comprehensive Plan

Potable Water Sub Element Water Supply

Protecting Water Sources (Quality) Water Conservation (Reducing Demand)

Reusing Stormwater Reusing Reclaimed Water

Comprehensive Plan

Conservation Element Recognize LID as Preferred Alternative

for Stormwater Management Allow Open Space Credit for LID

Techniques Tree Cover Preservation Green Infrastructure

Intergovernmental Coordination Establish Coordination Procedures with

WMD for LID Review / Approval

Comprehensive Plan

Capital Improvement Element Establish Level of Service Establish LID as Preferred Alternative for

Public Investment Funding Mechanisms for LID Fiscal Incentives for LID

Land Development Regulations Modify stormwater management

regulations to include LID Establish Levels of Service Establish criteria for consideration of

alternative designs Establish Procedures

Master Plan requirement Submission requirements Review / Approval process Coordination with WMD

Land Development Regulations Areas of code that should support

LID Natural area protection Open space requirements Clustering standards Water conservation requirements TDR programs Water quality protection

Land Development Regulations

Audit codes for obstacles Zoning / Land Use Regulations Stormwater Regulations

Requirement for conventional designs only No options for stormwater on private lots

Road requirements Parking / Other Design Criteria

Land Development Regulations

Recommendations Remove lot size requirements / use gross

density Provide credit for innovative design Allow stormwater systems to be located on lots Allow LID to be credited as open space Do not allow conventional basins in wetland

buffers Allow flexibility in road width/ design Curb & gutter optional

Design Guidelines

Put the details in Design Guidelines Buy-In by WMD

Sarasota County Model

Development Review

Make It Easy To Do the Right Thing Early Review Progressive Approval Engage WMD

Development Review

Roadblocks Requirements for engineering plans at

initial review stages Lack of early coordination with Water

Management District

Monitoring / Maintenance

Establish maintenance responsibility

Minimum criteria for homeowner’s association (financial responsibility / capacity)

Require periodic monitoring Require contract / agreement

Still not seeing any LID?If your code allows it, what’s stopping

it?

Is it public perception, State regulations, lack of expertise in the area, lack of examples, lack of education or knowledge that LID even exists, fear of doing something different, lack of staff support, etc…?

So what can local governments do?

The Role of Local Government Lead by example (Is your municipality or

county incorporating LID into their new projects or redevelopments?)

Provide incentives in your code for LID or stricter guidelines for water quality protection or water conservation.

Provide technical support (i.e. Sarasota LID Manual)

Are there opportunities for financial support?

Incentives and Regulations Give credit for LID (i.e. Alachua County

example – open space credit for LID techniques and enhanced stormwater basins)

Allow LID techniques to meet local water quality and quantity standards above WMD regulations

Include LID in Green building/development codes

Alachua County Example:Stormwater Areas Credited Toward Open Space1) Enhanced Basins:Provide greater biological diversityProvide enhanced stormwater treatment

- provide staged elevations - native trees in basin bottom

Irregular shorelinesPedestrian pathNo clearing, mowing or removal of native vegetation

orAlternative landscape plan with greater or equal biological diversity and enhanced stormwater treatment

2) LID that treats 1st inch and is pervious gets credit

Provide Technical Support Provide an LID manual, referenced in

the code. Make the manual consistent with

other communities that incorporate LID.

Consider expedited permits for LID projects or not charging for resubmittals

Train your staff.
