I've been addressing this to city officials for awhile now--with no results. Here's my latest attempt, emailed on July 30. Not one of the addresses has even bothered to reply to my email:
To: Alex Pullen, City Tax Assessor;
cc: Maurine Villani, Tax Collector; Dave Reyes, Jr., Ward 5 Alder [First St is in Ward 5]
Mr. Pullen,
I reported 2 of these vehicles on SeeClickFix (along with others) back on Nov. 30, 2018. You can see these here as proof that they have been here longer than 60 days**: seeclickfix.com/issues/5163810 AND seeclickfix.com/issues/5163818 ADDITIONALLY there is a Harley-Davidson motorcycle owned by same person and parked on that same block of First St (between Howard & Greenwich Aves), likewise registered in Vermont: VT motorcycle marker plate # KK273. (The motorcycle often is covered with a tarp, but parked on the street.) In fact, the owner of these 3 vehicles, who resides at 80 First St (first floor) has lived there for over 3 years! Traffic & Parking says this is not their purview to investigate registration violations. Police have not responded.
While I realize that your department does not have the staff to pursue all such violations, the evidence I have presented here should be sufficient to address two of these violations immediately--and ultimately the motorcycle, as well.
As a taxpayer who is weary of paying higher taxes because of tax scofflaws, it is my hope that you will put all 3 of these vehicles on the New Haven tax roll ASAP.
Thank you!
