Grade ordinance. The plan and profile of any proposed street shall contain sufficient information for the writing of a grade ordinance.
2. 
Easements. Easements of not less than five (5) feet in width shall be provided on each side of all rear lot lines and on side lot lines where necessary for poles, wires, conduits, storm and sanitary sewers, gas, and water mains.

Except in extremely unusual instances no dead end streets shall exceed six hundred (600) feet in length.

Whenever there is an adjoining street (a street that runs to the subdivision at an angle and not parallel or along the subdivision boundary) which has been platted as a public street but not improved and one hundred fifty (150) feet or less in length, the subdivider shall stand one-half (½) of the cost of improving said street; provided however, the Board of Aldermen shall deem said improvement necessary for the betterment of the City's Street system.
Whenever a subdivision line is parallel and along a publicly dedicated or used street, the subdivider shall, at his/her own expense, dedicate a strip of land lying within his/her subdivision so that the total street width meets the City requirements (Subsection (3) of this Section) and stand not to exceed one-half (½) the cost of improving the entire street adjacent the proposed subdivision inclusive of paving, grading, and storm sewers.

The grading, paving, and otherwise improving of such private streets shall conform to the requirements for publicly dedicated streets as set forth in this Chapter. The City of Shrewsbury will not assume liability or responsibility for maintenance on any street laid out as private until adjacent property owners repair and otherwise improve that portion of the street to City specifications and to a greater width if deemed necessary by the Board of Aldermen and said road and utility easements are dedicated to public use, said improvements shall have been made and accepted by the City of Shrewsbury not more than thirty (30) days prior to said dedication. Ingress to and egress from any private street shall not be denied to fire, police, or other public apparatus.
6. 
Lots. The minimum lot area of any lot in a subdivision shall not be less than the minimum lot area requirements of the Zoning Code covering that area in which the subdivision is located. Extra width shall be provided in all corner lots to provide at least the same building area as are provided on interior lots because of the side building line requirements of lots siding on streets. All side lines of lots shall be at right angles to straight street lines, or radial to curve street lines, unless variation to this rule will give a better street and lot plan. Double frontage lots shall be avoided.

All other points may be marked by monuments as defined under Section 435.010 of this Chapter.

Before the final plat of the subdivision shall be approved, the subdivider shall submit to the City Planning Commission a statement from the local postmaster approving the names of the proposed streets.
11. 
Subdivision name. Before the final plat of the subdivision shall approved, the subdivider shall present a signed statement that he/she has checked the existing subdivision names of record in the St. Louis County Recorder's Office and that there will be no duplication of names.

Grades. The maximum street grade shall be ten percent (10%) and all changes in street grade shall be connected by vertical curves of a minimum length equivalent to eight (8) times the algebraic difference in the rates of grade.
13. 
Improvements. Before approval of the final plat of any subdivided area minimum improvements as herein below specified shall be completed to the satisfaction of the City of Shrewsbury, however, in lieu of final completion of minimum improvements, the subdivider may post a surety bond or escrow agreement, approved by the Board of Aldermen, which bond or escrow agreement will insure to the City of Shrewsbury that the improvements will be completed by the subdivider within two (2) years after final approval of the plat. The amount of the bond or agreement shall not be less than the estimated cost of the improvements, and the amount of the estimate must be approved by the Board of Aldermen. If the improvements are not completed within the specified time, the Board of Aldermen may use the bond or draw upon the escrow or any necessary portion thereof the complete said improvements.
The minimum improvements installed in any subdivision before the plat can finally be approved shall be in accordance with the following Subdivisions: (a), (b), (c), and (d).

Whenever feasible, the sewers shall not be constructed within the anticipated paving area and house connections to each lot from the sanitary sewers shall be carried beyond the anticipated curb lines.
b. 
The subdivider shall install water mains and fire hydrants in the subdivided area. Such installations shall be approved by the Board of Aldermen and the Missouri Inspection Bureau. If the subdivider desires he/she may make the proper payment to the St. Louis County Water Company for the installation of the necessary water mains and fire hydrants and the receipt may be presented to the Board of Aldermen. The estimated cost of this improvement shall then be deducted from the estimated cost of improvements used to determine the amount of the bond or escrow agreement.

The sum of money required to be deposited by this Subsection may be used to cover the cost of engineering and inspection during construction which may become necessary and may be used to cover any and all costs or expenses the City may incur resulting from the construction of such public improvements or caused by any violation of any conditions or regulations in connection with said public improvements. In the event the City Engineer shall determine during any phase of construction of said public improvements, that additional funds may be required to meet the aforesaid cost, engineering or inspection fees then and in that event the Board of Aldermen may require the subdivider to deposit an additional amount of money with the City to cover such additional cost or fees.
