LAFAYETTE -- City leaders are set to discuss a proposal to place 47 townhome-style residences and live-work spaces in the west end.

The City Council, the Planning Commission and the Design Review Commission will meet Monday at the Lafayette Library & Learning Center community hall in a joint study session with representatives from Lennar Homes to discuss the project.

The San Ramon-based developer wants to build a multifamily residential development on three parcels at the corner of Mt. Diablo Boulevard and Dolores Drive.

At the council's Sept. 9 meeting, City Manager Steve Falk said the purpose of Monday's meeting is to gauge the city's receptivity to the proposal.

"Before they get into a formal application that would probably generate a lot of controversy if it exceeds the 35-foot height limit, (the developer) should have a 'temperature taking' ... to see whether the commissions are on board with something like that," Falk said.

The city permits building heights of up to 35 feet, unless the council approves an exception increasing the limit up to 45 feet. The developers are proposing heights of up to 45 feet for eight units that would sit on a hillside facing an East Bay Municipal Utilities District aqueduct right of way.

In addition to the row-style townhomes, the development would include a number of live/work units and garages that would be concealed from public view. In addition to existing on-street parking on Mt. Diablo Boulevard, the proposal calls for up to 100 parking spots for residents and 16 to 20 spaces for guests.

Lennar has also indicated that 15 percent of the units could be designated affordable to below-market-rate housing, which the city says is consistent with past practice under the former redevelopment agency. That would fall in line with a proposed draft "inclusionary housing ordinance" the council may consider this year.

The study session starts at 6 p.m.
