(Ord. 1676 § 61, 2008; Ord. 1685 § 1(Exh. A), 2009; Ord. 1954 § 32, 2016)
The applicant shall file with the director a list of all contractors and subcontractors who are to participate in the construction of all improvements that are required by this title. Such contractors and subcontractors shall be subject to the licensing requirements of the city and shall be subject to disqualification by reason of faulty performance of past construction work done for the city.
(Ord. 1676 § 63, 2008)
All improvements shall be subject to inspection by authorized representatives of the city, both during the course of construction and after construction is completed. The representatives shall have the authority to determine whether materials of construction, methods of construction and workmanship comply with working drawings, specifications, and city standards. The applicant shall provide for reasonable tests and proof of quality of materials as requested by any city representative. Any city representative may require that work be suspended for just cause including adverse weather conditions, poor workmanship, the use of substandard materials or methods of construction, and failure to adhere to specifications, drawings, and city standards. Approval by the inspector or absence of inspections shall not relieve the applicant of full responsibility for adherence to all specifications, working drawings, conditions of preliminary approval, and city standards. Approval by the inspector shall not be deemed final acceptance of the improvements by the city.
(Ord. 1676 § 64, 2008)
The applicant shall identify zones where existing vegetation will be protected and where soils with good infiltration capacity and suitable for infiltration as described in the stormwater management manual will be set aside for infiltrating on-site stormwater management facilities.
(Ord. 1954 § 33, 2016)
The proposed street layout shall conform to the general design criteria set forth below:
A. 
All streets shall be arranged in proper relation to topography and other site characteristics in a manner which results in usable lots, safe streets and acceptable gradients without unnecessary destruction of drainage courses, trees and other natural site features;
B. 
The arrangement of streets in new developments should be such that said streets extend to the boundary lines of the tract to make provision for future extension to adjacent tracts, except when determined to be impractical by the public works director or designee due to critical areas, site constraints, or existing street alignments;
C. 
The street layout shall reflect the use of local streets to provide access to abutting properties, and the use of collector streets to channel traffic through the development to abutting collectors and arterials. The layout should discourage the use of local streets by through traffic;
D. 
When lot(s) within a residential development are proposed adjacent to an arterial street, primary access to said lots shall be provided from a local street or collector street and a "no access" easement established along the lot boundary bordering the arterial;
E. 
All street intersections shall be perpendicular, unless a modified intersection is approved by the city's public works director or designee;
F. 
New streets shall not be connected or traffic from a proposed development discharged to a substandard roadway without minimum improvement to said roadway as determined to be needed by the city public works director or designee;
G. 
Cul-de-sacs are not permitted.
(Ord. 1676 § 65, 2008; Ord. 1685 § 1(Exh. A), 2009)

Paved rear alleys not less than 20 feet wide shall be required in all commercial, business, and industrial subdivisions except where special conditions make alleys impracticable. In such cases, adequate off-street loading space, suitably surfaced, shall be provided in accordance with FMC Title 19. Alleys shall be paved with a permeable pavement surfacing.

(Ord. 1676 § 67, 2008)
A. 
Residential. Curb radii shall not be less than 20 feet. Where an angle of intersection less than 70 degrees is permitted, curb radii shall be increased as necessary to ensure its safe usage.
B. 
Commercial. Curb radii shall not be less than 50 feet.
C. 
Industrial. Curb radii shall not be less than 70 feet.
(Ord. 1676 § 70, 2008)
The lengths, widths, and shapes of blocks shall be such as are appropriate for the locality and the type of development contemplated. Blocks in residential subdivisions shall not exceed 1,200 feet in length nor be less than 400 feet in length; blocks longer than 800 feet in length shall have pedestrian crosswalks not less than 10 feet wide within 100 feet of the midpoint of the block. In such blocks, the city may also require the reservation of an easement not less than 10 feet wide through the block to accommodate utilities, drainage facilities, or pedestrian traffic.

(Ord. 1676 § 72, 2008)
Where feasible, blocks adjacent to principal arterial and minor arterial streets shall be so arranged that the long dimension of the block be parallel to the arterial street and that lots do not front on or have access to the arterial street. Where this arrangement is not feasible, additional neighborhood access streets shall be required. Wherever practicable, blocks along arterial streets and collector streets shall not be less than 1,000 feet in length.
(Ord. 1676 § 73, 2008)

B. 
The city may require perpetual unobstructed easements at least 10 feet in width to provide pedestrian access from streets to schools, parks, playgrounds, or other nearby streets. Such easements shall be provided on the plat.

Each reservation shall be of suitable size, dimension, topography, and general character and shall have adequate street and pedestrian access for the particular purpose envisioned. The area shall be shown and marked on the preliminary plat, "Reserved for Park and/or Recreation Purposes." When recreation areas are required, the city shall determine the number of acres to be reserved from the standards set forth in the city's comprehensive parks, recreation and open space plan and the comprehensive plan's capital facilities element. The applicant shall dedicate all such reservation areas to the city or a homeowners' association as a condition of final subdivision plat approval.

All bonded improvements shall be designed and certified by or under the supervision of a registered civil engineer prior to the acceptance of such improvements. If an improvement bond or other guarantee has been submitted under this section, such guarantee shall only be released upon acceptance by the city of a properly executed bill of sale for such improvements and submittal of adequate "as-built" drawings for which the guarantee was submitted for.
(Ord. 1676 § 80, 2008)
The applicant, his contractors and suppliers shall be responsible to ensure that existing improvements and the property of the city are not damaged or rendered less useful or unsightly by the operations of the applicant, his contractors or suppliers. This provision is intended to include damage or nuisance with respect to natural features including but not limited to wetlands, critical aquifer recharge areas, fish and wildlife habitat conservation areas, frequently flooded areas, geologically hazardous areas, critical aquifer recharge areas, fish and wildlife habitat conservation areas, frequently flooded areas, geologically hazardous areas and seismic hazard areas; land, improvements or landscaping of the city; damage to existing streets, sidewalks, curbs and gutters by passage thereover of equipment or trucks or by excavation for any purpose; the spillage or tracking of earth, sand or rock onto existing streets, sidewalks, curbs and gutters; the washing by stormwater of earth or sand onto streets, sidewalks, curbs and gutters or into catch basins; and damage to water mains, sanitary sewers, culverts or storm sewers.
