Chuck Slotnick the owner of Alco Auto Parts store sincerely wants to develop his family’s 65 year-old-business on Hyde Park Avenue into “something that honors our family… to build a livable affordable community” with ARX Urban Development.

Instead he has unwittingly opened up a proverbial Pandora’s box of neighborhood rivalry between Forest Hills and Woodbourne.

This came crashing down at a hasty, tension-filled virtual meeting of the Forest Hills Neighborhood Association on Dec. 2. ARX development director Adam Giordano and architect Andreas Bernal of JGE were forced to rush through a 10-minute presentation of their 48-rental unit. six-story apartment house.

More than 40 people were on the call.

Moderator Keegan Dougherty was having no patience with anyone outside his Forest Hills group, “this is not an abutters meeting” he shut off one Woodbourne neighbor who interjected.

“We’re deprived of an opportunity to ask questions?” asked Mark Byrne.

Dougherty’s clock was ticking and ARX CEO Benjie Mohl was forced to concede that an abutters meeting was necessary.

“This is the first time I’m aware of an abutters meeting,” he said and vowed to hold an abutters meeting, “most certainly.”

The only public meeting required was the Oct.22 Boston Planning Department Article 80 hearing , which, as the Bulletin reported, was lightly attended. The comment period ended on Nov. 5 and neighbors instead vented online with 36 writing in opposition and 41 in favor; also submitted was a petition in support with 41 signatures. The Boston Planning and Development Agency Board will vote on approval of the Article 80 Small Project Review of the Zoning Code on Thursday.

Most in the opposition were in the “we approve, but” category.

Nancy Shapero of Rodman Street -who was on the Forest Hills call- was typical, “I support development for affordable housing but this is not a positive addition to the streetscape of Hyde Park Avenue,” she wrote.

Justin and Cassie Fitzpatrick from Wachusett Street added another common compliant, “Neighbors on Wachusett St were notified. The developer delivered to only the one side of the street. The even sided numbered houses were missed.”

Fitzpatrick lives on the odd side at number 231; its not clear of they were on the Article 80 call. Justin Fitzpatrick was on the Forest Hills N/A call.

“My impression is the developer is trying to bypass the neighborhood and push the project on them,” they wrote.

“This is a neighborhood is defined by kindness and civic engagement, values that align with affordable housing.”

“We are not opposed to adding housing. [But] we want housing that is not detrimental to the wellbeing of the neighbors,” Fitzpatrick wrote. “Six stories is too big.”

Jerry Jacobson minced no words.

“Is this a prison or a housing complex?” he wrote. “Why put the cheapest, prison-looking building in our neighborhood? Hyde Park Avenue is in horrible shape.”

Mark Finklestein lives on the odd-numbered side of Wachusett Street.

“I’m shocked and angered that there was no outreach to the abutters informing us of the hearing in October.”

The Planning Department advertised the hearing in The Bulletin.

“While I’m in favor of building affordable housing in Boston I believe the scale of this project will significantly detract from the peace and quiet and safety of my neighborhood. This project is reckless, underhanded and unconscionable,” Finklestein wrote.

Karti Subramanian of Patten Street included the support petition signed by 41 Woodbourne neighbors into the comments page.

Rarely heard spoken in Jamaica Plain but always between the lines are the words “not-in-my-backyard,” but Subramanian got to the point in his written statement.

“Incredibly hypocritical NIMBYism already coming from our neighborhood,” he wrote, “make the same tired arguments about insufficient process. This from a neighborhood that was explicitly redlined to keep Blacks and Jews out.”

Finklestein’s Wachusett Street neighbor Jacob Beizer, who was on the Forest Hills call, had a different view.

“I’m writing in support of this project, I live on the same block, my neighbors’ concerns are misplaced,” he wrote,

“People can’t claim to be in favor of solving the housing shortage problem in Greater Boston while opposing and stonewalling any new construction because of mild nuisances.”

Margaret Smith-Oliver was a “But.”

“We fully support more houses along Hyde Park Avenue and believe in building inclusive accessible neighborhoods but we have serious concerns about the impact this specific proposal will have on our Woodbourne community,” she wrote.

“When we moved here last year, we were drawn to the spirit of community. We want new development that will not erode our character.”

Jonathan Goldenberg, Elizabeth Hirsch and Holly Woods were all in support.

“Please do not listen to the NIMBYs,” Goldenberg wrote. “This is my neighborhood. I live close by and I strongly support this development.”

Hirsch added, “Please do not be swayed by the NIMBYs,”she wrote, “We welcome new neighbors.”

Woods wrote to “express my enthusiastic support for this project.”

“I have seen many comments from my neighbors expressing concern… I vehemently disagree with [them].To say you support more housing and affordable housing but not here and not like this is the very definition of NIMBYism.”

“ I do not believe a group of well-off homeowners (myself included) should have the power to derail much needed housing,” Woods wrote.
