Addition Improvements, and that Basin A will be expanded with approval from the Iowa
DNR. Please Clearly label these grading plans as the Initial Grading Improvements for
Heartland Heights First Addition, and add a note to these plans that these Plan of
Improvements are the initial grading and erosion control plan of improvements, and that
the final overall grading and erosion control plans for Heartland Heights First Addition will
be submitted for review and approval upon the Iowa DNR's approval for the additional
grading of Basin A.
2. On the Cover Sheet, please revise the Index of sheets to reflect only the General Notes
and the Grading and Erosion Sheets.
3. On the General Notes Sheet, please remove the notes that do not pertain to the site
grading, erosion and sediment control, and site restoration. Please also add the list of
CR Standard Details to this sheet that only pertain to the site grading, erosion and
sediment control, and site restoration for this site. Please make sure that all notes
pertain to this project, and the City of Fairfax.
4. Clearly label all proposed contours at 5' intervals, including north of Beverly Road and
south of Heartland Street.
5. There appears to be low points with the proposed contours plan where water will pond.
Please address these, and label all low point and high point contours.
6. Please label Beverly Road within the proposed grading limits on Plan Sheet C5.1.
7. Please clean up the proposed contours.
8. On the Grading Plan Sheets, please show the location where the SWPPP/ NPDES
Permit is being stored on-site. Please note what is being used to house this document,
and who is the responsible person (Name and Contact Information) who is maintaining
this document.
9. Please clearly identify and label the slopes for all side slopes that are at a 4:1 slope or
steeper. No slopes steeper than 3:1 are acceptable, with 4:1 being the preferable
maximum slope.
10. Remove services from the grading plan sheets, and clean-up the utilities so that they all
have the same legible line type scales.
11. Please show and label (type and size) all existing and proposed easements on the
grading plan sheets.
12. On Plan Sheet C5.0, how is Borrow Area 2 accessed? If a new stream crossing of the
east-west creek is necessary, please show this, with the proposed type, size and length
of culvert proposed.
13. What is the proposed outlet protection at the outlet of the existing culvert under 80th
Street at the southeast corner of this Addition? What is the proposed outlet protection of
the proposed culverts under Bridgewood Drive and Eagleview Drive? Please show
these, and provide the design information for these.

prior to grading over the existing gas main. Please copy me and the City of Fairfax with
Mid-American Energy's Comments/Approval.
16. There appears to be a drainage swale located along the south property line of Heartland
Heights First Addition. The proposed contours along this drainage swale do not appear
to contain the drainage in this swale within the storm water drainage easement. Please
provide a typical section of this swale and make sure that the proposed contours reflect
this typical section.
17. The proposed drainage swale along the south property line of Heartland Heights First
Addition shall be constructed and final graded and seeded as part of the plan of
improvements. Please reflect this in a note.
18. On Plan Sheet C5.0, The existing wetlands and the north-south and east-west streams
are shown with 50' and 100' protective buffers respectively. It is my understanding that
the wetlands are currently grassed and not farmed. Is this correct? Is the area around
the north, west and south sides of this wetland area planned to be farmed? If not, then
this area should be grassed as well. Please show the existing grassed areas of the
wetlands and along the two streams, and the proposed grass buffer areas around the
wetlands and streams as well.
19. As part of the Site Restoration Plan, please show the farming limits along the exterior of
the site, and the existing ground cover(with type of cover) to be maintained on the site
and adjacent to this site. Please also show the proposed ground cover and note the type
of cover and whether or not this is a temporary ground cover of permanent ground cover.
The permanent drainage swale along the south property line, as well as the Beverly Road
right-of-way should be final graded with topsoil and seeded with permanent ground cover.
20. Are the stockpile and construction entrance locations as shown on the grading plan
consistent with what is currently being done on-site by the contractor? Please coordinate
with the contractor on this and revise accordingly.
21. Please provide 4 sediment traps (per SUDAS 7E-13). These should be located along the
permanent and temporary swales at the following locations: North side of Lot 183, the
south side of Lot 88, the south side of Lots 96 & 97, and the south side of Lots 11 & 12.

from the Public R.O.W.'s and that fill placed within the Public R.O.W. shall consist of
approved materials which are free of organic matter and debris. That fill within the
R.O.W. shall be placed in loose lifts of 9" or less, and that fill within the public R.O.W. that
is greater than 18" shall be tested per the Cedar Rapids Metropolitan Area Standards
Specifications, Section 01110, 3.02—Geotechnical Testing. Please provide the locations
where these tests shall be required (Street names and stationing) and please have these
test results submitted to the City of Fairfax and Hall and Hall Engineers, Inc.
24. Under the Surface Restoration Notes, No. 1, please revise this note to say that"All
disturbed areas not paved or hard surfaced shall receive a minimum of 6"? of topsoil.
Scarify areas...." The City only required a minimum of 4" of topsoil, but if the owner/
developer prefers 6", this is also acceptable.
