Subject: Mitigated Negative Declaration (MND) For Carmel Hill and River Class I Bicycle Trail Project
Dear Mr. Muck:
The League of Women Voters of the Monterey Peninsula has reviewed the MND for the Carmel Hill and River Bicycle Trail. The project is a 1.7 mile, 12-foot wide bicycle trail between the Crossroads and Canyon Drive, a cul-de-sac, withan undercrossing at Carmel Valley Road. We have the following comments:
Page 1. The MND notes the Biological Assessment is currently undergoing final changes to
comply with recent "regulatory input". As of September 4, the document was not posted on the
TAMC website. The comment period for review of the MND should be extended to enable public
review of an updated Biological Assessment.
Page 55. The MND concludes, "For these reasons, the impact of diesel exhaust from this
construction project is anticipated to contribute negligibly to an increased cancer risk for
each individual sensitive receptor and would be considered less-than-significant". This
conclusion is based on a qualitative rather than a quantitatively analysis. Further, the
analysis fails to address acrolein, a toxic air contaminant resulting from the combustion of
diesel exhaust. Since there are residences within 1/4 mile of proposed construction activity
and acrolein adversely affects those with respiratory problems including asthma, a quantitative
risk assessment of diesel exhaust emissions and acrolein should be undertaken
Page 56. The MND concludes, "It is anticipated that the project meets the suitability
criteria for the U.S. Fish and Wildlife Service Programmatic Biological Opinion (2003)". The
document indicates that all mitigation measures outlined by the U.S. Fish and Wildlife Service
shall be implemented. Without identification of these mitigation measures, it is not possible
for the Lead Agency to determine if they are feasible and if an MND is the appropriate
environmental document. The MND should be recirculated once the mitigation measures have been identified.
Page 58. Protection of Smith's blue butterfly depends on unidentified mitigation
measures. See item 3 above.
Page 58. The MND states that a qualified biologist shall prepare and implement a
Wetland and Riparian Restoration and Monitoring Plan which will identify needed mitigation
measures. Once again, without identification of needed mitigation measures, the MND is
incomplete and should be revised and recirculated once the information is available
Pages 67 and 68. The MND finds the project includes new impervious surfaces totaling
2.6 acres and storm water will sheet flow from the paved surfaces to nearby unpaved areas where
it will percolate or flow into the creek or storm culvert and the trail would result in an
increase in the amount of surface runoff during storm events. Policy 3.1.1.2 of the Carmel
Valley Master Plan includes a provision "... for slow release of runoff water so that runoff
rates after development do not exceed rates prevailing before development...". The project is
inconsistent with this policy. Were project alternatives or mitigation measures considered
that would reduce impervious surfaces such as a narrower bicycle path?
Page 75 and 76. The MND indicates the project would reduce traffic along Highway 1" by
providing a more accessible alternative transportation option (bicycle and pedestrian)."
Table 8 provides estimates of bicycle and pedestrian trip generation of up to 100 trips during
Sunday mid-day peakes. These estimates were based on pedestrian and bicycle counts at six
locations along the Monterey Bay Coastal Trail (p. 12, Appendix K). All of the locations were
segments of a connected trail system. The proposed project stops at Carmel Hill without any
northern connectivity. Given the lack of connectivity, the assumption that the trail would
provide an alternative transportation option is very highly questionable. Further, the short
length of the trail would limit its appeal to recreational bicycle users. The trip estimates
appear too high and should be revised based on data of comparable trail systems.
Thank you for the opportunity to review and comment on the document.
