The improvements set forth below shall be considered the minimum improvements necessary to protect the public health, safety, and welfare (per Iowa Code § 364.1).
(A) Streets and alleys. All streets and alleys within the platted area which are dedicated for public use shall be brought to the grade approved by the governing body after receiving the report and recommendations of the City Engineer.
(B) Roadways. All roadways shall be surfaced with Portland cement concrete or with asphaltic concrete over a crushed stone base as the governing body may require.
(C) Curb and gutter. Curb and gutter shall be required on all streets. All curb and gutter shall be constructed to the grade approved by the governing body after receiving the report and recommendations of the City Engineer. Newly constructed curbs and gutters shall comply with the Americans With Disabilities Guidelines (ADAAG).
(D) Sidewalks.
(2) Sidewalks shall be placed four feet behind the curb parallel to the street, unless an exception has been permitted by the city to preserve topographical or natural features or to provide visual interest, or unless the subdivider shows that an alternative pedestrian system provides safe and convenient circulation.
(3) In planned developments, sidewalks (as used in this subsection) may be located away from the road system to link dwelling units with other dwelling units, and the street to on-site activity centers such as parking areas and recreational areas. Developer may also be required to install sidewalks parallel to the street.
(4) For all zoning districts, sidewalks must be installed before the earliest of the following events:
(a) Sidewalks must be installed along the frontage of an improved property before occupancy is permitted. The City Council has granted an extension of time to install the required sidewalk.
(b) Upon 80% of lots in any subdivision being served by sidewalks, the remaining properties, unserved by sidewalks, shall have sidewalks installed within two years whether the remaining lots are developed or not. The mailing of a letter to the property owner by the city that 80% of lots have sidewalks shall serve as the starting point of the two-year period.
(c) All sidewalks in a subdivision must be installed within five years (or suggestions of a date) of the date on which the City Council approved the final plat.
(d) If an undeveloped lot is sold to an owner of an adjacent developed lot for use as part of the adjacent developed lot or for a future undetermined purpose, the undeveloped lot must have sidewalks installed within 30 days of the date of sale unless an extension is granted by the City Council, which shall only be granted for good cause shown.
(e) Any undevelopable lots, lots on which stormwater detainage/retainage is located, or lots to be used for other purposes, such as parks and/or public areas, shall have sidewalks installed by the developer, at developer’s expense, within one year of the City Council approval of the final plat unless an extension is granted by the City Council which shall only be granted for good cause shown.
(E) Water lines. Where a public water main is reasonably accessible, the subdivider shall connect with such water main and provide a water connection for each lot with service pipe installed to the property line in accordance with the City Water Department standards, procedures, and supervision.
(F) Sewers.
(1) Where a public sanitary sewer is reasonably accessible, the subdivider shall connect or provide for the connection with such sanitary sewer and shall provide within the subdivision the sanitary sewer system as required to make the sewer accessible to each lot in the subdivision. Sanitary sewers shall be stubbed into each lot. Sewer systems shall be approved by the governing body and the State Department of Health, and the construction subject to the supervision of the Superintendent of Public Utilities.
(2) Where sanitary sewers are not available, other facilities, as approved by the governing body and the State Department of Health, must be provided for the adequate disposal of sanitary wastes.
(3) Adequate provisions shall be made for the disposal of stormwaters, subject to the approval of the governing body and to the supervision of the Superintendent of Public Utilities.
