When the City determines that, subject to Section 430.080(A), additional information is required on properties to protect against landslides, faults or other geological hazards, the applicant shall submit an engineering geology report. The report shall be based on adequate and necessary test borings and give an adequate description of the geology of the site, with conclusions and recommendations, regarding the effect of geologic conditions on the proposed development and giving opinions and recommendations covering the adequacy of site to be developed by the proposed land disturbance activity. Recommendations included in the report and approved by the City shall be incorporated in the SWPPP. The report shall be based on subsurface exploration and testing that represents conditions of the entire parcel. The report shall include:
1.
Maps
depicting regional geologic settings and site-specific geologic formations
and structures.
2.
Review
of generally accepted published geologic reports pertaining to the
area.
3.
An adequate
description of the geology of the site, including description of bedrock
lithology, structure and physical characteristics (strength, jointing,
weathering, hardness, special physical or chemical features) and discussion
of how the geologic structure affects the site.
4.
Identification
of active and dormant landslides based on both site analysis and published
geologic maps. Geologic cross sections where appropriate to convey
information on geologic relationships.
5.
Discussion
of geomorphology and relevant hillslope and stream processes. Identification
and evaluation of any faults on or adjacent to the site, including
their degree of activity and their possible engineering significance.
6.
Description
and evaluation of off-site geologic hazards that may affect the graded
site.
7.
Conclusions
and recommendations regarding the effect of geologic conditions on
the proposed development.
8.
These
studies shall be performed for the entire parcel and shall not be
limited only to those portions to be graded.
9.
Reports
should be signed by a Missouri licensed professional engineer.
