NOTES TO CONTRACTOR:
ALL PADS SHOULD BE TESTED TO ASSURE A COMPACTION OF AT LEAST 95 PERCENT OF THE
MAXIMUM DRY DENSITY USING THE STANDARD PROCTOR TEST METHOD.
ANY PRIVATE TILES LOCATED ON THIS SITE WILL NEED TO BE LOCATED; BREATHERS SET AT THE
DOWNSTREAM PROPERTY LINE AND CRUSHED OR REMOVED ACROSS THIS SITE. IF ANY OF THESE
TILES EXTEND BEYOND THE LIMITS OF THIS PROJECT, THEY WILL NEED TO BE PROVIDED A
POSITIVE OUTLET AND ALLOWED TO CONTINUE TO FUNCTION, AS IT IS ILLEGAL TO BLOCK OFF A
PRIVATE "MUTUAL" TILE.
CONTRACTOR SHALL VERIFY DEPTHS OF ALL EXISTING ONSITE UTILITIES PRIOR TO
CONSTRUCTION TO CONFIRM THERE IS NOT ANY CONFLICTS WITH OTHER UTILITIES, STORM
SEWERS OR STREETS. CONFLICTS AFTER CONSTRUCTION BEGINS ARE SOLELY THE
CONTRACTOR'S RESPONSIBILITY.
ALL PAVING WITHIN THE EXISTING AND PROPOSED CITY RIGHT-OF-WAY SHALL CONFORM TO
THE REQUIREMENTS OF THE DEPARTMENT OF ENGINEERING. THE CONTRACTOR SHALL
CONTACT THE DEPARTMENT OF ENGINEERING TO SCHEDULE A PRE -CONSTRUCTION MEETING TO
REVIEW THE DEPARTMENT'S CONSTRUCTION REQUIREMENTS, STAFF NOTIFICATION
REQUIREMENTS, REQUIRED INSPECTIONS FOR CERTAIN STAGES OF THE WORK AND TO REVIEW
THE AUTHORITY OF THE DEPARTMENT AS IT RELATES TO WORK WITHIN THE EXISTING AND
PROPOSED RIGHT -OF WAY.
EXISTING PAVEMENT TO BE SAW CUT TO A CLEAN EDGE ADJACENT TO ANY WIDENING,
AUXILIARY LANES, ETC.
NO EARTH DISTURBING ACTIVITY MAY TAKE PLACE WITHOUT AN APPROVED STORM WATER
MANAGEMENT PERMIT.
THERE IS TO BE NO DRIVEWAY ENCROACHMENTS INTO EASEMENTS BETWEEN LOTS.
UTILITY RELOCATIONS REQUIRED BY THE PROJECT SHALL BE THE RESPONSIBILITY OF THE
DEVELOPER. UTILITY LINE RELOCATIONS REQUIRED FOR ROAD PROJECTS THAT RESULT IN A
CONFLICT WITH PROPOSED DEVELOPMENT SHALL BE THE RESPONSIBILITY OF THE DEVELOPER
TO RESOLVE WITH THE UTILITY. EXISTING POLE LINES REQUIRED TO BE RELOCATED TO WITHIN
ONE FOOT OF PROPOSED RIGHT-OF-WAY LINE.
DAMAGE TO THE EXISTING RIGHT-OF-WAY SHALL BE RESTORED/REPAIRED TO THE
SATISFACTION OF THE CITY AT THE COMPLETION OF THE PROJECT. THE CONTRACTOR IS
ENCOURAGED TO INSPECT THE RIGHT-OF-WAY WITH THE CITY PRIOR TO THE START OF
CONSTRUCTION TO DOCUMENT THE EXISTING CONDITION OF THE RIGHT-OF-WAY.

EARTHWORK:
1. EXCAVATION
A. Excavated material that is suitable may be used for fills. All unsuitable material and
all surplus excavated material not required shall be removed from the site.
B. Provide and place any additional fill material from offsite as may be necessary to
produce the grades required on plans. Fill obtained from offsite shall be of quality as
specified for fills herein and the source approved by the Developer. It will be the
responsibility of the Contractor for any costs for fill needed.
2. REMOVAL OF TREES
A. All trees and stumps shall be removed from areas to be occupied by a road surface or
structure area. Trees and stumps shall not be buried on site.
3. PROTECTION OF TREES
A. The Contractor shall, at the direction of the Developer, endeavor to save and protect
trees of value and worth which do not impair construction of improvements as designed.
B. In the event cut or fill exceeds 0.5 foot over the root area, the Developer shall be
consulted with respect to protective measure to be taken, if any, to preserve such trees.
4. REMOVAL OF TOPSOIL
A. All topsoil shall be removed from all areas beneath fixture pavements or building.
Topsoil removal shall be to a minimum depth of 6 inches or to the depth indicated in the
geotechnical report provided by the Developer to be excavated or filled. Topsoil should
be stored at a location where it will not interfere with construction operations. The
topsoil shall be free of debris and stones.
5. UTILITIES
A. Rules and regulation governing the respective utility shall be observed in executing all
work under this section.
B. It shall be the responsibility of the Contractor to determine the location of existing
underground utilities 2 working days prior to commencing work. For utility locations to
be marked call Toll Free 1-800-382-5544 within Indiana or 1-800-428-5200 outside
Indiana.
6. SITE GRADING
A. Do all cutting, filling, compacting of fills and rough grading required to bring entire
project area to subgrade as shown on the drawing.
B. The tolerance for paved areas shall not exceed 0.05 feet above established subgrade.
All other areas shall not exceed 0.05 feet plus or minus the established grade. Provide
roundings at top and bottom of banks and other breaks in grade.
C. The Engineer shall be notified when the Contractor has reached the tolerance as stated
above, so that field measurements and spot elevations can be verified by the Engineer.
The Contractor shall not remove his equipment from the site until the Engineer has
verified that the job meets the above tolerance.

Minimum Flood Protection Grades
From Sections 104.02, 302.06 and 303.07 of the City of Carmel Storm Water Technical
Standards Manual
1. Definitions
a. Minimum Flood Protection Grade of all structures fronting a pond or open
ditch shall be no less than 2 feet above any adjacent 100-year local or
regional flood elevations, whichever is greater, for all windows, doors, pipe
entrances, window wells, and any other structure member where floodwaters
can enter a building.
b. Lowest Adjacent Grade is the elevation of the lowest grade adjacent to a
structure, where the soil meets the foundation around the outside of the
structure (including structural members such as basement walkout, patios,
decks, porches, support posts or piers, and rim of the window well.
2. Standard: Lowest Adjacent Grade
a. General
i. The Lowest Adjacent Grade for residential, commercial, or industrial
buildings shall have two feet of freeboard above the flooding source's
100-year flood elevation under proposed conditions.
b. For areas outside a Special Flood Hazards Area (SFHA) or FEMA or TDNR
designated floodplain
i. The Lowest Adjacent Grade for all residential, commercial, or industrial
buildings adjacent to ponds shall be set a minimum of 2 feet above the
100-year pond elevation or 2 feet above the emergency overflow weir
elevation, whichever is higher.
ii. The Lowest Adjacent Grade for all residential, commercial, or industrial
buildings shall be set a minimum of 2 feet above the highest noted overflow
path/ponding elevation across the property frontage.
iii. In addition to the Lowest Adjacent Grade requirements, any basement floor
must be at least a foot above the normal water level of any wet -bottom pond.
3. Design Notes:
a. Each lot that is adjacent to a pond, open ditch or flooding source has a flood
protection grade. There are instances where there are multiple different
flooding sources for 1 structure. In this case, there should be a flood
protection grade listed for each side of the structure in the event that piping
from the structure discharge to either flood source.
b. Finished floor elevation or the lowest building entry elevation shall be no less
than 6 inches above finished grade around the building. Also, the building's
lowest entry elevation that is adjacent to and facing a road shall be a
minimum of 15 inches above the road elevation.
