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 & DesignLow 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
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 Space 1) Enhanced Basins: Provide greater biological diversity Provide enhanced stormwater treatment - provide staged elevations - native trees in basin bottom Irregular shorelines Pedestrian path No clearing, mowing or removal of native vegetation or Alternative 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.
