First download the City of New Haven Complete Streets manual (http://www.cityofnewhaven.com/Engineering/pdfs/CS-Manual-FINAL.pdf). At the end of the manual is an application that must be completed and submitted. You should contact your Alder person and Doug Hausladen, Director of Transportation and your District Manager. Also, attending your Management Team Meeting (tonight at 6:00pm) will put you in touch with people in your neighborhood (residents and city officials) who can help you to address this.
