OSRD and LID Putting What We’ve Learned on the Books and in the Ground OSRD and LID Putting What We’ve Learned on the Books and in the Ground

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development There are several questions local decision makers must answer before drafting an OSRD/LID Ordinance: 1)Which local board or agent will grant the permit? 2)What is the Permit mechanism (Special Permit, by right, etc.)? 3)Will there be a Permit trigger (development scale, etc.)? 4)What are the resource protection priorities of the community? 5)How will the Bylaw affect other local regulations? 6)What sort of administrative burdens will these create? 7) What sort of incentives or bonuses can the community comfortably and effectively promote?

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development ORDINANCE CONSIDERATIONS #1 and #2: Which local board or agent will grant the permit? What is the Permit mechanism? In many communities, the Planning Board is best suited to be the permit granting authority as they also review subdivision applications. OSRD/LID may be offered as a by-right development option, through Site Plan Review, or as Special (Use) Permit. Communities should assess how permitting is currently structured in their bylaw and use those mechanisms that have proven effective in the past. Application requirements should overlap other permit requirements to the greatest possible extent to make things easier on the applicant.

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development ORDINANCE CONSIDERATIONS #2 and #3: What is the Permit Mechanism? Will there be a Permit Trigger? Some Examples… Allowed by right…No trigger (may require incentives). Special Permit...Number of lots for OSRD or LID (example: 5 or more). Approval from New Authority…Scale of Development for Stormwater Bylaw (example: 5,000 square feet or more) Standard Approval of OSRD Definitive Plan…Triggered by jurisdiction of other agencies (example: Conservation Commission)

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development ORDINANCE CONSIDERATION #4: What are the resource protection priorities of the community? Resource priorities could include farmland, coastal areas, aquifers, sensitive habitats, historic buildings, forested areas, etc. The resource priorities will help shape the approach to site plan development. The permitting authority must be able to clearly communicate the resource priorities to the applicant in order to streamline the permitting process.

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development ORDINANCE CONSIDERATION #5: How will the Ordinance affect other local regulations? The Ordinance is not written in a vacuum. The writers should solicit input from all applicable agencies such as: DPW/Fire Chief Conservation Commission/Administrator Board of Health Zoning Board of Appeals/Zoning Board of Review Planning Board Building Inspector/Building Official Conflicts with existing regulations or other bylaws should be resolved before the ordinance is brought to Town Meeting/Council.

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development ORDINANCE CONSIDERATION #6: What sort of administrative burdens will this create? Will the permitting stream be clear if there is more than one agency with jurisdiction? If a new permitting authority is created, who will assume the responsibility? Will there be provisions to hire consultants for review? Zoning? Rules and Regulations? Other? Monitoring Requirements Enforcement

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development ORDINANCE CONSIDERATION #7: What sort of incentives or bonuses can the community comfortably and effectively promote? The goals discussed in other planning documents should be consulted before determining different density bonuses: Planned Production Plan (affordable housing) Open Space and Recreation Plan Executive Order 418 Community Development Plan Master Plan/Local Comprehensive Plan Offering bonuses or incentives may require a considerable outreach effort.

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development Affordable Housing  Communities may offer bonuses beyond the site yield if developers include affordable housing in their proposal.  Common provisions are on additional market rate unit for every one to two affordable units.  Developers incorporating compact housing design, such as townhouses, may find this a viable option. COMMON DENSITY BONUSES

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development Historic Structures Communities with historic homes on farms or other large tracts of land may offer bonuses to developers who preserve these structures. Rehabilitation of existing structures may prove to be a good investment if additional market rate units result from these efforts. COMMON DENSITY BONUSES

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development Increased Open Space OSRD Bylaws may have a minimum percentage of protected open space for a site such as 50%. Bylaw provisions may offer density bonuses for proposals that offer significant percentages beyond the minimum. Developers should carefully examine the flexible dimensional regulations of the bylaw to see if they can possibly gain more open space towards a density bonus. COMMON DENSITY BONUSES

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development Amenities to the Community OSRD Bylaws may have provisions where housing units may be increased if a clear amenity is provided to the community as part of the development. Developers facing this provision should be creative and consider such options as cluster wastewater systems, recreational facilities, public access to open space areas, pedestrian or bicyclist improvements, etc. COMMON DENSITY BONUSES

Blackstone Valley Stormwater Conference Ordinance/Bylaw Development COMMUNITY OUTREACH: An OSRD/LID Bylaw will have to be adopted at Town Meeting or by Council Vote. Common concerns include: 1)Will flexible provisions increase the amount of housing in the community? 2)How will the style of housing affect community character? 3)Could new development have unintended fiscal impacts? 4)How will density incentives increase the development potential of the community? 5)Are developers being given too much latitude?
