§ 40-171. Permit to construct public improvements.

(a)

Required. A person commits an offense if he constructs, alters or removes any public improvement without a permit for the work from the city.

(b)

Application procedures. The developer shall submit an application for the permit on standard forms provided by the city. The application shall be accompanied by three complete sets of proposed construction documents. Such plans and one set of construction cost estimates shall bear the seal of an engineer registered in the state, and shall be prepared in accordance with the latest city standards.

(c)

Issuance and fees. A permit for construction, alteration or removal of public improvements can be issued upon approval of the engineered plans and cost estimates (see subsection (d) of this section) for the work and payment of a plan checking and inspection fee in accordance with the duly adopted schedule of fees. Where more than one type of public improvement (i.e. water lines, sewer lines, streets, etc.) are shown on the same design plans, individual permits shall be issued for each type of public improvement.

(d)

Construction documents.

(1)

Street construction documents. The developer shall submit street plans with a plan and profile of all proposed streets or roads with centerline and top of curb grades, ditch flowline and tops of ditch grades, and showing existing and proposed surface profiles. Each sheet shall include north point, scale, date and benchmark description to sea level datum. Scales shall be one inch equals 40 feet horizontally and one inch equals four, five or ten feet vertically. Each plan shall show all existing and proposed public improvements (drainage, sewer, water, etc.) within the limits of the street construction. The typical cross section of proposed streets showing the width of roadways and type of pavement and location and width of sidewalks shall be shown. Each plan shall show the seal and signature of the registered professional engineer who prepared the plans.

(2)

Grading plan. The developer shall submit a plan of the entire tract depicting the final grading contours and elevations, earthwork, quantities (cut and fill), slopes, retaining walls, drainage patterns, finished floor elevations of all existing structures, minimum floor elevations of all future structures and any other information considered necessary by the city at a scale of one inch equals 100 feet minimum.

(3)

Design summary. The developer shall submit a separate report entitled "Engineering Design Summary" with final plans and specifications for construction of public improvements and shall summarize calculations and such other engineering information pertaining to the major items of design significance as may be necessary in the city's review of the plans and specifications to determine whether the facilities proposed for construction have been designed in accordance with the intent of the city's design criteria. Calculations shall include drainage facilities, water demand, sewage flows and any others considered necessary by the city.

(4)

Format.

a.

The developer shall submit all improvement plans to the city on sheets 24 inches by 36 inches. A binding margin shall be provided of not less than one and one-half inches on the left side of the sheet and margins not less than one-half inch on the three other sides.

b.

Upon approval by the city of the engineering plans and conditional approval of the final subdivision plat, the developer will be issued a permit to construct public improvements.

c.

Upon completion of the required public improvements, the developer's engineer, registered in the state, shall present to the city on high quality, reproducible drafting film (four mils thick) complete as-built plans for all paving, drainage structure, storm drains, water lines and sewer lines within 30 days of the completion of each contract. The engineer shall also submit one electronic copy each of the as-built plans in "dwg" and "tiff" formats. The "tiff" copy shall include the engineer's seal, signature and date. The engineer shall confirm in writing that the as-built documents are in fact true representations of the actual construction.

d.

The city shall not accept ownership or maintenance of any public improvements until the developer submits all final plats, all as-built documents relating to the project to the city and a one-year maintenance bond.
