A. GENERAL NOTES
1. All materials, workmanship, and construction of public improvements shall meet or exceed the standards and specifications set forth in the Larimer
County Urban Area Street Standards and applicable state and federal regulations. Where there is conflict between these plans and the
specifications, or any applicable standards, the most restrictive standard shall apply. All work shall be inspected and approved by the City of Fort
Collins.
2. All references to any published standards shall refer to the latest revision of said standard, unless specifically stated otherwise.
3. These public improvement construction plans shall be valid for a period of three years from the date of approval by the City of Fort Collins Engineer.
Use of these plans after the expiration date will require a new review and approval process by the City of Fort Collins prior to commencement of
any work shown in these plans.
4. The engineer who has prepared these plans, by execution and/or seal hereof, does hereby affirm responsibility to the City of Fort Collins, as
beneficiary of said engineer's work, for any errors and omissions contained in these plans, and approval of these plans by the City of Fort Collins
Engineer shall not relieve the engineer who has prepared these plans of all such responsibility. Further, to the extent permitted by law, the engineer
hereby agrees to hold harmless and indemnify the City of Fort Collins, and its officers and employees, from and against all liabilities, claims, and
demands which may arise from any errors and omissions contained in these plans.
5. All storm sewer construction, as well as power and other "dry" utility installations, shall conform to the City of Fort Collins standards and
specifications current at the date of approval of the plans by the City of Fort Collins Engineer.
6. The type, size, location and number of all known underground utilities are approximate when shown on the drawings. It shall be the responsibility of
the Developer to verify the existence and location of all underground utilities along the route of the work before commencing new construction. The
Developer shall be responsible for unknown underground utilities.
7. The Developer shall contact the Utility Notification Center of Colorado (UNCC) at 1-800-922-1987, at least 2 working days prior to beginning
excavation or grading, to have all registered utility locations marked. Other unregistered utility entities (i.e. ditch / irrigation company) are to be
located by contacting the respective representative. Utility service laterals are also to be located prior to beginning excavation or grading. It shall be
the responsibility of the Developer to relocate all existing utilities that conflict with the proposed improvements shown on these plans.
8. The Developer shall be responsible for protecting all utilities during construction and for coordinating with the appropriate utility company for any
utility crossings required.
9. If a conflict exists between existing and proposed utilities and/or a design modification is required, the Developer shall coordinate with the engineer
to modify the design. Design modification(s) must be approved by the City of Fort Collins prior to beginning construction.
10. The Developer shall coordinate and cooperate with the City of Fort Collins, and all utility companies involved, to assure that the work is
accomplished in a timely fashion and with a minimum disruption of service. The Developer shall be responsible for contacting, in advance, all
parties affected by any disruption of any utility service as well as the utility companies.
11. No work may commence within any public storm water, sanitary sewer or potable water system until the Developer notifies the utility provider.

CONTROL MEASURES ACCORDING THE THE CONSTRUCTION
SEQUENCING AND LEVEL OF SITE STABILIZATION.
5. CONTRACTOR SHALL IMPLEMENT APPROPRIATE INLET PROTECTION
FOR ALL STORM DRAINS, SWALES, PONDS AND RAIN GARDENS UNTIL
SITE IS FULLY STABILIZED.
6. CONTRACTOR SHALL IMPLEMENT APPROPRIATE INLET PROTECTION
FOR DOWNSPOUT CONNECTIONS, TO THE STORM DRAIN SYSTEM,
UNTIL CONNECTION IS ESTABLISHED WITH DOWNSPOUT.
7. INLET PROTECTION SHALL BE ADAPTED, AS NECESSARY, TO THE
SURROUNDING SURFACE TYPE AND CONDITION (i.e., STAKE-DRIVEN
WATTLES FOR BARE SOIL, SAND BAGS OR GRAVEL SOCKS FOR
PAVEMENT, ETC.)
8. CONTRACTOR IS RESPONSIBLE FOR STABILIZING ALL SLOPES,
PARTICULARLY THOSE STEEPER THAN 6:1. CRIMP MULCHING,
HYDRO MULCHING, EROSION MATS, TEMPORARY IRRIGATION, AND
ADDITIONAL WATTLES OR SILT FENCING MAY BE NECESSARY TO
ESTABLISH VEGETATIVE COVER AND STABILIZE THE SLOPE.

CREATE BLOWING DUST WHICH, IN THE INSPECTOR'S OPINION, IS
HAZARDOUS TO THE PUBLIC HEALTH AND WELFARE.
14. WHERE SEASONAL CONSTRAINTS (E.G., DURING SUMMER AND
WINTER MONTHS) INHIBIT PERMANENT SEEDING OPERATIONS,
DISTURBED AREAS WILL BE TREATED WITH MULCH AND MULCH
TACKIFIER OR OTHER MATERIALS APPROVED BY EROSION CONTROL
STAFF TO PREVENT EROSION.
15. SEE LANDSCAPE PLANS FOR ADDITIONAL INFORMATION ON
PLANTING, REVEGETATION, HARDSCAPE AND OTHER PERMANENT
