Dear Ms. Giudice:

 

The Sierra Club – Marin Group believes the above Draft Negative Declaration (Neg Dec) is inadequate in that it does not account for recent and significant developments in the immediate area, namely the acquisition of the Felton property for near-term use as an expansion of the existing Manzanita Park-and-Ride facility and for intermediate-term term use as a new “visitor intercept facility” of as many as 400 cars for a Muir Woods shuttle.  In contrast, page 28 of the Neg Dec notes: “the Felton property at 101 Shoreline Highway (proposal for an office complex).”

 

There is a significant difference between an office complex and a visitor intercept facility.  The Muir Woods shuttle will necessarily run on a reservation basis, with the 400 cars cycling through as many as four times per day.  This could mean as many as 1600 visitor cars cycling through Tam Junction on high visitor days.  Preliminary Muir Woods visitor studies show about half of its visitors originate from San Francisco, many of whom may decide to gas up before returning.  Gas station traffic resulting from the proposed visitor intercept facility will be very much higher than that from employee cars of an office complex.   Therefore mitigation F1 (page 29), the “fair share fee” to be paid by the developer is based on much too low a number.

 

Even if the fair share mitigation fee were corrected to reflect a visitor intercept facility, the physical mitigations for gas station traffic impacts are inadequate.   The proposed exit/merge lane (F2 and F3. page 30) is the same as at Mill Valley’s East Blithedale / Ashford Avenue intersection.  It does not work well at the Blithedale location and it will work even less well at the Tam Junction location. The Blithedale location stacks up at the Ashford stop sign as the front car hesitates to cross the oncoming traffic, or stacks up even further as drivers unfamiliar with the east bound merge lane wait for an opening in traffic going both ways.  At least, the Blithedale location offers both a long merge with east bound traffic for drivers who make it across and alternate routes to access East Blithedale for drivers who give up waiting. 

 

On the other hand, the Tam Junction gas station will have a larger number of visitor cars less familiar with the proposed exit/merge lane, and no alternate route to get onto Shoreline in the inevitable stack up.  Furthermore, the vast number of those cars exiting east successfully will want to head to San Francisco, and thus will be faced with a short distance to cross over two lanes.  We do not doubt that based on the (incorrect) assumption of a Felton office complex and a hypothetical traffic calculation, mitigations F2 and F3 might seem to work.   In the real world, however, the proposed mitigations will create a traffic nightmare in Tam Junction, already a difficult traffic location.   We urge that you require any project here, particularly a gas station, must have safe and effective east turn solutions demonstrated to have worked in the real world.

 

Sincerely,

Addendum to Sierra Club letter of June 19, 2002

Dear Ms. Giudice:

 

The Sierra Club – Marin Group wishes to make explicit what was implicit in our letter of June 19, 2002:   The Club believes that the above Draft Negative Declaration does not contain adequate and correct information or mitigations sufficient to insure that the traffic impacts have been mitigated to less then significant effect.  Thus the Club does not agree with the proposal for a negative declaration conclusion from the Initial Study for the above gas station project.  

 

Due to the intensity of traffic through the Tam Junction area, and the changing circumstances brought about by the several on-going planning efforts underway (TTIP, CMPT), the Club specifically requests that a focused EIR on traffic impacts be undertaken to insure that all relevant information is incorporated into planning for the proposed gas station.  

  

Sincerely,

 

Gordon Bennett, Conservation Co-Chair
