The Minor Amendment plan for the Fontaine Townhomes, received on 4 June 2008, has been
reviewed. The plans cannot be approved as submitted and will require the following
changes /corrections prior to approval. Engineering review staff is available from 2 -4 PM on
Thursdays to discuss these review comments. Please contact an engineer to schedule an
appointment.
A. General Review Comments:
1. Plan sheets have discrepancies and inconsistencies that do not allow for an adequate
review or approval as submitted. Please make sure all plan sheets are congruent for
an adequate review. Additional comment and/or conditions will be forthcoming once
all plan sheets agree.
2. Please correct the reference numbers on the cover sheet to match the ones found in the
County system. The last approved Site plan is SDP200700069 and Water protection
is WP0200700049.
3. Page 8 of 20 appears to have a layer from the existing site condition turn on.
B. SDP - 2008 - 00092, Minor Site Plan Amendment review comments:
4. Drainage easements will be shown a minimum 20' in width with exception to the
pipes requiring more width due to size and depth of pipe in accordance with DSM
1101. See Figure 11 -1 "Determination of Drainage easement Widths" for Calculation
and description.
5. Please extend drainage easement at structures 2 1 B to the Flood plain and clearly label.
6. Please show and label drainage easements for all stormwater drainage structures on
plan to match the proposed plat. All downspout collector pipes will be considered
private systems and will require a private easement if crossing property lines.
7. A safety railing is required for any wall whose height is over 4ft. Please note this on
the grading plan and provide for it on the wall detail.
8. Please show all proposed drainage profiles in the Site plan.
9. Retaining walls appear different on sheet 10 of 20 from other sheets.
C. WPO- 2008 - 00061, Minor WPO Amendment review comments:
10. Designs and details for sediment basins are missing and could not be reviewed at this
time.
11. Each underground detention structure requires an access manhole for inspection and
possible cleaning and maintenance.
12. Please show TS and PS on all phases of the plan where appropriate. PS is especially
important on the embankment for sediment basins. Please provide B/M on this 2:1
slope as well. [VESCH]
13. Additional comments may be forthcoming on the next submittal due to the required
changes.
14. Depending on the degree of variance from the approved plan, a new Water protection
bond may have to be calculated.
