CGS LAND USE REVIEWS
Geological studies are required by Colorado counties for all subdivisions of unincorpo-
rated land into parcels of less than 35 acres, under State statute C.R.S. 30-28-136 (1) (i)
(Senate Bill 35, 1972). Some Colorado municipalities require geological studies for sub-
division of incorporated land. In addition, local governments are empowered to regu-
late development activities in hazardous or mineral -resource areas under C.R.S. 24-65.1-
101 et seq. (House Bill 1041, 1974) and C.R.S. 34-1-301 et seq. (House Bill 1529, 1973),
respectively.
Local -government agencies submit proposed subdivision applications and supporting
technical reports to the Colorado Geological Survey "...for evaluation of those geologic
factors which would have significant impact on the proposed use of the land," in accor-
dance with State statutes. The CGS reviews the submitted documents and serves as a
technical advisor to local -government planning agencies during the planning process.
Since 1984, the CGS has been required by law to recover the full direct cost of perform-
ing such reviews.
The adequate knowledge of a site's geology is essential for any development project. It
is needed at the start of the project in order to plan, design, and construct a safe devel-
opment. Proper planning for geological conditions can help developers and future
owners/users reduce unnecessary maintenance and/or repair costs.

Frequently Asked Questions and Answers
Regarding the CGS Land Use Review Process
1 Why am I required to have a CGS review when I already hired
and paid for my own consultant?
In 1972, Senate Bill 35 was passed stating that any person or
entity subdividing a property into parcels of 35 acres or less on
unincorporated land must submit geologic or geotechnical
reports to the County as part of the preliminary plat application
process. Municipalities or public agencies may request that CGS
review a site, although these reviews are not governed by the
statute.
2 Why is a CGS review necessary when I already hired my own
geologist?
The CGS review is an independent third -party review that is done
for the County, similar to the service a building inspector provides
for construction review. The purpose of the CGS review is to
ensure that all geologic concerns have been adequately identified
and addressed in the geologic reports and that the proposed
development is feasible.
3 Why does CGS charge for land use reviews? Doesn't taxpayer
money pay for this service?
CGS land use reviews are not subsidized through the general
fund, although some other review agencies are supported by
taxpayer money. In 1984 the state legislature decided that CGS
reviews should be paid for with fees paid by the applicant of the
proposed development so that taxpayers are not viewed as
subsidizing development.
4 Did the CGS geologist make a field visit to the site?
A CGS geologist visits each site being reviewed. If the review is a
re -submittal for a site that has been visited previously, a second
site visit may not be necessary. If significant changes have
occurred since the initial review, the site may be visited again.
5 Why is the CGS review letter so short and simple? What is my fee
paying for?
The CGS letter is a review of the geologic material submitted and
reflects the level of detail contained in those documents. CGS does
not offer designs, but rather ensures that the work that has been
done is meaningful and adequate for the site conditions and
proposed development. A site review that adequately addresses all
the geologic conditions present at the site may be a short
confirmation letter. If more work needs to be done or if difficult
site conditions are present, the letter may be longer.
6 What type of information do I need to submit to CGS for a land
use review?
The more geologic information that is submitted to CGS, the
easier it is for CGS to evaluate the property. The required
documents may vary based on county requirements and the
potential problems that may impact the proposed development.
A topographic map is essential. Also, information regarding
slope, surficial materials, subsurface materials and bedrock,
presence of groundwater and depth, and specific geologic
hazards should be included, where applicable. Grading plans,
drainage plans, and geotechnical testing results are also very
helpful for the review. The presence of geologic hazards should
be evaluated with respect to the development plan. Also, the
effect of development on geologic conditions should be
discussed. The evaluation should include alternatives such as
avoidance and mitigation techniques.
7 The subdivision down the road was approved, why wasn't mine?
There could be several reasons: geologic conditions can change
over short distances; subdivisions made prior to 1972 were not
required to undergo a CGS review and may have not been
evaluated for geologic suitability at all; the area down the road
may be incorporated as part of a municipality, which exempts it
from the CGS review process. Another consideration is that
geologic reviews are continually evolving and site conditions that
have been judged acceptable in the past may no longer be
considered as such, based on the current understanding of the
geologic processes and adverse impacts associated with them.
8 Why are CGS reviews required even on low-density properties?
Senate Bill 35 pertains to subdivisions of less than 35 acres.
Geologic hazards can occur on Large -scales or small -scales;
relying on low-density subdivision can not mitigate all geologic
hazards. For instance, entire hillsides might be prone to rockfall
or landslide hazards. Large tracts of land may be subject to
groundwater problems.
9 Why can't I just use the soil conservation maps for a geologic
report?
The USDA soil conservation maps are a good start for geologic
investigations, but do not contain sufficient detail on the possible
geologic problems that may occur at any site.
10 Aren't some of your review comments beyond the scope of geologic
hazards on my site?
Technically other agencies have regulatory authority regarding
issues such as flood plains, groundwater availability and wildfire,
but these issues are also important factors in the overall geologic
context of the site and may affect geologic hazards on the site. The
mention of a condition in the CGS review letter is not intended to
influence the statutory authority of any other agency, but rather to
ensure that all parties are aware of a potentially problematic
geologic condition. For instance, mention of a situation involving a
major drainage is a flag that the U.S. Army Corps of Engineers or
the Colorado Water Conservation Board should be reviewing
development plans.
11 When I bought this property, no one told me about any geologic
hazards on the site; can I go back to the previous owners
somehow?
CGS can not give legal advice. If the seller was aware of adverse
conditions with respect to the proposed use, this should have
been disclosed. A legal opinion should be sought.
12 Can I get a waiver from having the CGS do a review?
The discretion to grant waivers is vested by law with the counties.
Once an application for review is submitted to CGS, we are under
a statutory responsibility to respond.
13 I am willing to accept the risk associated with my property —
why is it anyone's business what I do with my own land?
The presumption associated with a subdivision is that portions
of the property will be sold to others. This then assigns any risk
to future buyers, and the county is required to protect their
interests. Senate Bill 35 addresses a wide variety of land use
issues as well as geologic suitability in an attempt to provide
information so that the overall appropriateness of the
subdivision proposal can be evaluated.
