6.All soils exposed during land disturbing activity (stripping, grading, utility installations, stockpiling, filling, etc.) shall be kept in a roughened condition
by ripping or disking along land contours until mulch, vegetation, or other permanent erosion control BMPs are installed. No soils in areas outside
project street rights-of-way shall remain exposed by land disturbing activity for more than thirty (30) days before required temporary or permanent
erosion control (e.g. seed/mulch, landscaping, etc.) is installed, unless otherwise approved by the City/County.
7.In order to minimize erosion potential, all temporary (structural) erosion control measures shall:
a.Be inspected at a minimum of once every two (2) weeks and after each significant storm event and repaired or reconstructed as necessary in
order to ensure the continued performance of their intended function.
b.Remain in place until such time as all the surrounding disturbed areas are sufficiently stabilized as determined by the erosion control inspector.
c.Be removed after the site has been sufficiently stabilized as determined by the erosion control inspector.
8.When temporary erosion control measures are removed, the Developer shall be responsible for the clean up and removal of all sediment and
debris from all drainage infrastructure and other public facilities.

15.To ensure that sediment does not move off of individual lots one or more of the following sediment/erosion control BMPs shall be installed and
maintained until the lots are sufficiently stabilized, as determined by the erosion control inspector. a.) Below all gutter downspout. b.) Out to
drainage swales. c.) Along lot perimeter. d.) Other locations, if needed.
16.Conditions in the field may warrant erosion control measures in addition to what is shown on these plans. The Developer shall implement whatever
measures are determined necessary, as directed by the City
17.A Vehicle Tracking Control Pad shall be installed whenever it is necessary for construction equipment including but not limited to personal vehicles
existing roadways. No earthern materials, i.e., stone, dirt, etc., shall be placed in the curb & gutter or roadway as a ramp to access temporary
stockpile(s), staging area(s), construction material(s), concrete washout areas(s) and/or building site(s).
18.For additional information see separate Stormwater Management Plan / Erosion Control Report for MAXFIELD SUBDIVISION 2ND FILING.
B. Street Improvement Notes
1.All street construction is subject to the General Notes on the cover sheet of these plans as well as the Street Improvements Notes listed here.
2.A paving section design, signed and stamped by a Colorado licensed Engineer, must be submitted to the City of Fort Collins Engineer for approval,
prior to any street construction activity, (full depth asphalt sections are not permitted at a depth greater than 8 inches of asphalt). The job mix shall
be submitted for approval prior to placement of any asphalt.
3.Where proposed paving adjoins existing asphalt, the existing asphalt shall be saw cut, a minimum distance of 12 inches from the existing edge, to
create a clean construction joint. The Developer shall be required to remove existing pavement to a distance where a clean construction joint can
be made. Wheel cuts shall not be allowed unless approved by the City of Fort Collins Engineer in Fort Collins.

5.Valve boxes and manholes are to be brought up to grade at the time of pavement placement or overlay. Valve box adjusting rings are not allowed.
6.When an existing asphalt street must be cut, the street must be restored to a condition equal to or better than its original condition. The existing
street condition shall be documented by the Inspector before any cuts are made. Cutting and patching shall be done in conformance with Chapter
25, Reconstruction and Repair. The finished patch shall blend smoothly into the existing surface. The determination of need for a complete overlay
shall be made by the City of Fort Collins Engineer. All overlay work shall be coordinated with adjacent landowners such that future projects do not
cut the new asphalt overlay work.
7.All traffic control devices shall be in conformance with these plans or as otherwise specified in M.U.T.C.D. (including Colorado supplement) and as
per the Right-of-Way Work Permit traffic control plan.
8.The Developer is required to perform a gutter water flow test in the presence of the City of Fort Collins Inspector and prior to installation of asphalt.
Gutters that hold more than 1/4 inch deep or 5 feet longitudinally, of water, shall be completely removed and reconstructed to drain properly.
9.Prior to placement of H.B.P. or concrete within the street and after moisture/density tests have been taken on the subgrade material (when a full
depth section is proposed) or on the subgrade and base material (when a composite section is proposed), a mechanical "proof roll" will be required.
The entire subgrade and/or base material shall be rolled with a heavily loaded vehicle having a total GVW of not less than 50,000 lbs. and a single
axle weight of at least 18,000 lbs. with pneumatic tires inflated to not less that 90 p.s.i.g. "Proof roll" vehicles shall not travel at speeds greater than
3 m.p.h. Any portion of the subgrade or base material which exhibits excessive pumping or deformation, as determined by the City of Fort Collins
Engineer, shall be reworked, replaced or otherwise modified to form a smooth, non-yielding surface. The City of Fort Collins Engineer shall be
notified at least 24 hours prior to the "proof roll." All "proof rolls" shall be preformed in the presence of an Inspector.
C. Traffic Signing and Pavement Marking Construction Notes
1.All signage and marking is subject to the General Notes on the cover sheet of these plans, as well as the Traffic Signing and Marking Construction
Notes listed here.
2.All symbols, including arrows, ONLYS, crosswalks, stop bars, etc. shall be pre-formed thermo-plastic.
3.All signage shall be per the City of Fort Collins Standards and these plans or as otherwise specified in MUTCD.
4.All lane lines for asphalt pavement shall receive two coats of latex paint with glass beads.
5.All lane lines for concrete pavement should be epoxy paint.
6.Prior to permanent installation of traffic striping and symbols, the Developer shall place temporary tabs or tape depicting alignment and placement
of the same. Their placement shall be approved by the City of Fort Collins Traffic Engineer prior to permanent installation of striping and symbols.
7.Pre-formed thermo-plastic applications shall be as specified in these Plans and/or these Standards.
8.Latex paint applications shall be applied as specified in CDOT Standard Specifications for Road and Bridge Construction.
9.All surfaces shall be thoroughly cleaned prior to installation of striping or markings.
10.All sign posts shall utilize break-away assemblies and fasteners per the Standards.
11.A field inspection of location and installation of all signs shall be performed by the City of Fort Collins Traffic Engineer. All discrepancies identified
during the field inspection must be corrected before the 2-year warranty period will begin.
12.The Developer installing signs shall be responsible for locating and protecting all underground utilities.
13.Special care shall be taken in sign location to ensure an unobstructed view of each sign.
14.Signage and striping has been determined by information available at the time of review. Prior to initiation of the warranty period,the City of Fort
Collins Traffic Engineer reserves the right to require additional signage and/or striping if the City of Fort Collins Traffic Engineer determines that an
unforeseen condition warrants such signage according to the MUTCD or the CDOT M and S Standards. All signage and striping shall fall under the
requirements of the 2-year warranty period for new construction (except fair wear on traffic markings).
15.Sleeves for sign posts shall be required for use in islands/medians. Refer to Chapter 14, Traffic Control Devices, for additional detail.
16.Contractor is responsible for removing all anchors, posts, signs and/or delineators in Construction area. Contractor may keep the signs, or call the
City Traffic Division to have them removed.

HDPE pipe shall be SDR 9 having a pressure rating of 200 psi. Stiffeners shall be used at all fittings and connections. Tracer wire shall be
installed with the HDPE service, and shall extend up the curb stop. The curb stop shall be covered with a metal valve box and "water" lid per City
Water Detail 11A.
INFILL AND REDEVELOPMENT NOTE
A.Despite everyone's best efforts, it is impossible to fully display subsurface information prior to excavation. This is especially
true in areas of infill and redevelopment. Unknown subsurface conditions can have cost and schedule implications. Prior to
finalizing contract terms, it is strongly recommended that the Owner and General Contractor have a candid discussion to formulate
a strategy for dealing with such circumstances when they arise. The process and procures should be in place prior to excavation.
Allowances and contingencies can address the cost implications, but additional measures are required to deal with scheduling and
factors impacting sequence of work. The Architect, Engineer(s), and Construction Surveyor should be made aware of the protocol
for dealing with such unknown subsurface conditions prior to starting work.

W1 NOTES:
INSTALLATION:
WHEN INSTALLING RUNNING LENGTHS OF WATTLES, BUTT THE SECOND
WATTLE TIGHTLY AGAINST THE FIRST, DO NOT OVERLAP THE ENDS. STAKE
THE WATTLES AT EACH END AND FOUR FOOT ON CENTER. FOR EXAMPLE:
A 25 FOOT WATTLE USES 6 STAKES
A 20 FOOT WATTLE USES 5 STAKES
A 12 FOOT WATTLE USES 4 STAKES
STAKES SHOULD BE DRIVEN THROUGH THE MIDDLE OF THE WATTLE.
LEAVING 2 - 3 INCHES OF THE STAKE PROTRUDING ABOVE THE WATTLE. A
HEAVY SEDIMENT LOAD WILL TEND TO PICK THE WATTLE UP AND COULD
PULL IT OFF THE STAKES IF THEY ARE DRIVEN DOWN TOO LOW. IT MAY BE
NECESSARY TO MAKE A HOLE IN THE WATTLE WITH A PICK END OF YOUR
MADDOX IN ORDER TO GET THE STAKE THROUGH THE STRAW. WHEN
STRAW WATTLES ARE USED FOR FLAT GROUND APPLICATIONS, DRIVE THE
STAKES STRAIGHT DOWN; WHEN INSTALLING WATTLES ON SLOPES, DRIVE
THE STAKES PERPENDICULAR TO THE SLOPE.
DRIVE THE FIRST END STAKE OF THE SECOND WATTLE AT AN ANGLE
TOWARD THE FIRST WATTLE IN ORDER TO HELP ABUT THEM TIGHTLY
TOGETHER. IF YOU HAVE DIFFICULTY DRIVING THE STAKE INTO EXTREMELY
HARD OR ROCKY SLOPES, A PILOT BAR MAY BE NEEDED TO BEGIN THE
STAKE HOLE.

W2 NOTES:
INSTALLATION:
STAKES SHOULD BE DRIVEN ACROSS FROM EACH OTHER
AND ON EACH SIDE OF THE WATTLE. LEAVING 4"-6" OF
STAKE PROTRUDING ABOVE THE WATTLE. BAILING WIRE OR
NYLON ROPE SHOULD BE TIED TO THE STAKES ACROSS
THE WATTLE. STAKES SHOULD THEN BE DRIVEN UNTIL THE
BAILING WIRE OR NYLON ROPE IS SUFFICIENTLY SNUG TO
THE WATTLE.
WHEN INSTALLING RUNNING LENGTHS OF WATTLES, TO
PREVENT SHIFTING, BUTT THE SECOND WATTLE TIGHTLY
AGAINST THE FIRST. DO NOT OVERLAP THE ENDS. STAKES
SHOULD BE DRIVEN 1 FT. FROM END, ACROSS FROM AND
ON EACH SIDE OF WATTLE LEAVING 4"-6" OF STAKE
PROTRUDING ABOVE THE WATTLE. BAILING WIRE OR
NYLON ROPE SHOULD BE TIED TO STAKES IN AN HOUR
GLASS FORMATION (FRONT TO BACK OF WATTLE "A",
ACROSS TO FRONT OF WATTLE "B", ACROSS TO BACK AND
BACK TO FRONT OF WATTLE "A"). STAKES SHOULD THEN BE
DRIVEN IN UNTIL BAILING WIRE OR NYLON ROPE IS

WEIGHTED WATTLE
W1 & W2 INSTALLATION NOTES:
1. THE LOCATION AND LENGTH OF WATTLE IS DEPENDENT ON THE CONDITIONS OF EACH SITE.
2. WATTLES SHALL BE INSTALLED PRIOR TO ANY LAND-DISTURBING ACTIVITIES.
3. WATTLES SHALL CONSIST OF STRAW, COMPOST, EXCELSIOR, OR COCONUT FIBER.
4. NOT FOR USE IN CONCENTRATED FLOW AREAS.
5. THE WATTLES SHALL BE TRENCHED INTO THE GROUND A MINIMUM OF TWO (2) INCHES.
6. WATTLES SHALL BE INSTALLED PER MANUFACTURERS SPECIFICATIONS.
7. ON SLOPES, WATTLES SHOULD BE INSTALLED ON CONTOUR WITH A SLIGHT DOWNWARD ANGLE AT THE END OF THE ROW IN ORDER TO PREVENT
PONDING AT THE MID SECTION.
8. RUNNING LENGTHS OF WATTLES SHOULD BE ABUTTED FIRMLY TO ENSURE NO LEAKAGE AT THE ABUTMENTS.
9. SPACING - DOWNSLOPE:
VERTICAL SPACING FOR SLOPE INSTALLATIONS SHOULD BE DETERMINED BY SITE CONDITIONS. SLOPE GRADIENT AND SOIL TYPE ARE THE MAIN
FACTORS. A GOOD RULE OF THUMB IS:
1:1 SLOPES = 10 FEET APART
2:1 SLOPES = 20 FEET APART
3:1 SLOPES = 30 FEET APART
4:1 SLOPES = 40 FEET APART, ETC.
HOWEVER, ADJUSTMENTS MAY HAVE TO BE MADE FOR THE SOIL TYPE: FOR SOFT, LOAMY SOILS - ADJUST THE ROWS CLOSER TOGETHER;
FOR HARD, ROCKY SOILS - ADJUST THE ROWS FURTHER APART. A SECONDARY WATTLE PLACED BEHIND THE ABUTMENT OF TWO WATTLES IS
ENCOURAGED ON STEEP SLOPES OR WHERE JOINTS HAVE FAILED IN THE PAST.
10. STAKING: THE CITY RECOMMENDS USING WOOD STAKES TO SECURE THE WATTLES. 1/2" TO 5/8" REBAR IS ALSO ACCEPTABLE. BE SURE TO USE A
STAKE THAT IS LONG ENOUGH TO PROTRUDE SEVERAL INCHES ABOVE THE WATTLE: 18" IS A GOOD LENGTH FOR HARD, ROCKY SOIL. FOR SOFT
LOAMY SOIL USE A 24" STAKE.
4"-6" ABOVE WATTLE AFTER BAILING WIRE
OR NYLON ROPE IS ATTACHED. STAKES
NEED TO BE TAMPED UNTIL WIRE/ROPE IS
SNUG WITH WATTLE.
W3 NOTE:
IF THE AREA BEHIND THE INLET IS NOT STABILIZED, A
BMP SHOULD BE USED TO PREVENT SEDIMENT FROM
ENTERING THE INLET
1"x 1" WOOD STAKES
18"-24"
THE CONTRACTOR SHALL INSPECT WATTLES EVERY TWO WEEKS AND AFTER ANY SIGNIFICANT STORM EVENT AND MAKE REPAIRS OR REMOVE SEDIMENT

SEDIMENT ACCUMULATED BEHIND WATTLE SHALL BE REMOVED WHEN THE SEDIMENT HAS ACCUMULATED TO ONE HALF THE DIAMETER OF THE WATTLE.
WATTLES SHALL REMAIN IN PLACE UNTIL THE UPSTREAM DISTURBED AREA IS STABILIZED AND IS ACCEPTED BY THE CITY.
