Before it imposes new requirements, the Boston Planning & Development Agency is asking developers for examples of successful strategies to meet Mayor Michelle Wu’s three-legged reform platform of resiliency, affordability and equity.

In issuing the questionnaire to developers and community groups, BPDA staff will use the voluntary responses to develop a scorecard that would incentivize projects that include best practices in the areas, following a public review.

“This challenge is the first step in a comprehensive process to ensure that development in Boston prioritizes resilience, affordability, and equity from start to finish,” Chief of Planning Arthur Jemison said in a statement.

Wu’s proposed increases in affordable housing requirements have been criticized by real estate industry groups and developers, who predict the changes would make multifamily projects harder to finance.

The questionnaire seeks details on housing projects’ plans for home ownership units, rents and unit sizes, affordability percentages and displacement risk. The affordability section also asks developers for “data-specific outcomes” that can be used to grade how projects support goals such as mobility, public transit usage, and growth without displacement.

Wu also has called for a new focus on coastal resiliency as part of the permitting process.

Developers have been designing flood resilience projects for individual parcels and tying them into plans by abutters and public agencies. The proposed Dorchester Bay City project would include a 23-foot-tall flood barrier, and recently relocated two buildings’ location further from the waterfront.

The city has taken climate studies into account in planning coastal resiliency projects for publicly owned properties, including sea walls on Fort Point Channel and the Raymond L. Flynn Marine Park.

The BPDA also has asked a consultant to study flooding at Long Wharf and prevent storm surges from inundating portions of the Financial District.

But the city has yet to develop a formula for splitting the estimated multi-billion-dollar cost of future coastal resiliency projects with private land owners.

The Climate Ready Boston study estimated that 870 downtown properties are vulnerable to climate change-induced flooding, with potential damages of $1.4 billion to real estate and infrastructure.
