City of Cambridge loses Millions in Parking Revenue

 News from Finance Committee Hearing May 11, 2022

City of Cambridge Parking Revenue is “now about $4 million or $5 million behind”  One Reason according to Joe Barr is “the Cycling Safety Ordinance, which adds bike lanes to narrow Cambridge streets often at the expense of parking spots. “The vast majority of tickets we issue are meter tickets. If you remove meters, you remove the opportunity to write tickets on those meters.”

Cambridge's initial budget $55 Million for 2 -1/2 Miles of Bike Lanes

Letter from the City Manager April 7, 2022


The timeline for completion of the improvements is based on the best available information. As we work with the community to develop the detailed designs, we will have more information on the full scope of the projects and also develop a strategy for how best to phase the improvements to mitigate the impacts of construction. The estimated budget for these projects ($40M for Segments A & B and $15M for Segments C & D) is being included in the recommended budget that will be forwarded to the City Council in May.

Total Contract value for Engineering Services alone to date for Quick-Build projects below

Engineering support contract calls for concept design, preliminary design and final design plans along with other deliverable documents.  


Here are some facts from Public Records requests and appeal to the State Supervisor of Public Records:

 

  1. MassAve4 - $55M to be included in FY23 Proposed Budget
  2. Porter Square - $0.73M for additional funding requested by City Manager and approved by City Council 
  3. River Street Reconstruction - $25M bond approved; City staff will not answer if all/none/part of this project is considered CSO implementation 
  4. $1.53M for House Doctor Designer Services for Engineering Support for: 

  • Porter Square/Fresh Pond Pkwy to Mason or Mason to Mt. Auburn (Alfred Benesch & Co) 
  • Mass Ave - Dudley St to Alewife Brook Pkwy Mass Ave/Trowbridge St to Inman St (Kleinfelder 8412CC)
  • MassAve4 (Kleinfelder 8412QQQ) 
  • Engineering services for a total of 5.69 miles of separated bike lanes or  $268,772.23/mile.  Extrapolating this to 25 miles of CSO implementation would result in $6.72M for engineering support alone
  • Total actual cost of installing the bike lanes (lane painting; traffic signs; flexi posts etc) is unknown. 


 One can only guestimate the cost of the implementation of Quick Build based on the two Quick Build projects


Statistics Regarding Bicycling in Cambridge

Second Annual Cycling Safety Ordinance Progress Report: 

• Outlines work completed and work planned for Separated Bike Lanes

• Counts mileage totals as indicated in the Cycling Safety Ordinance.

• Separated Bike Lane Construction Summary 

 

This report raises more questions than it answers.

It doesn’t include information on Parking that has been and will be removed, or the information on the effects on Businesses as required by POR 2022 #29 or input from stakeholders as required POR 2021 #277 . It doesn’t include data on Accidents, or the financial effects of building costs and revenue lost.

 At the City Council Meeting on 6/13/22 Councilor Toner requested an addendum with this missing information, and the request was agreed to be Joe Barr, head of the Cambridge transportation Department. 


 2020 Cambridge Bicycle Plan Report

2019  City of Cambridge Census report says:   68.6% of Cambridge households have at least 1 car,  31.4% of Cambridge households do not own a car  Cambridge rating for accessible by bike score is already at the highest mark on the scale in 2019 prior to the completion of the bike lane    Journey to work-- 32% drive alone or carpool, 29.8  by transit,  only 7% bike   

Crash Data for the Dudley to Alewife Brook Parkway

Crash Data for the Dudley to Alewife Brook Parkway Project Area

Crash Data for the Dudley to Alewife Brook Parkway Project Area

10 accidents involving cyclists from 1/24/2018 to 8/24/2021 over 3 ½ years of data   


Resulting injuries of these accidents involving bikes:   

4  - No Injury  3 -  Possible injury  3 -  Non‐ incapacitating 


6 of the accidents involved turns, which would not have been prevented by protected lanes.

There is a completely off road bike path connecting Arlington with Davis Square and The Alewife MBTA station,   which could be the reason for the low crash and injury rate in this area of Mass Ave.  


Crash Rates 2004-2019

Crash rates involving bicycles are down:  

36% from 2004 – 2019. 


Crashes are trending down even before the bike lane and even with an increase of bicycle ridership


The report says by 2020 10% of all trips in Cambridge will be made by bike, projects the number to climb to 20% by 2030 - still a low percentage of all travel

Reports on crashes severity involving cyclists comparing statistics from 2004-2012 (8 year span) with Crashes from 2015-2019 (a 4 year span) by percentages.
