All improvements shall be designed and constructed in conformance with the city's comprehensive plan, the applicable facility plans, Entiat city ordinances and codes and all engineering design standards. Prior to the construction of any improvements as required by the preliminary approval, the project proponent shall submit construction plans. These plans must be prepared, signed, dated and stamped by a Washington State licensed civil engineer and shall be in accordance with the city of Entiat engineering design standards. The construction plans must be reviewed and approved by the city prior to construction.
(Ord. 572 § 1, 2001; Ord. 701 § 1 (Exh. A), 2009; Ord. 857 § 8, 2023)
Upon receipt of construction plans prepared in compliance with the approved preliminary plat, the city engineer shall review the construction plans and shall inform the subdivider of any errors, omissions, or corrections to the data supplied which are required. When the city engineer finds the data submitted to be sufficient, and that all provisions of the city of Entiat Standard Plan Guidebook and EMC Title 19 have been complied with, the city engineer shall sign the construction plans and authorize construction to begin in accordance with Chapter 19.02 EMC.
(Ord. 572 § 1, 2001; Ord. 701 § 1 (Exh. A), 2009; Ord. 857 § 8, 2023)
Improvements shall be constructed under the supervision and to the satisfaction of the city engineer or, if authorized or required by the city engineer, the developer may be compelled to provide his own engineer for the purpose of inspecting and certifying that all public improvements have been accomplished according to city standards. The city engineer may require changes in typical sections and details in the public interest if unusual conditions arise during the construction to warrant such changes. The city may decline to accept any responsibility for the maintenance of streets and utilities until all improvements are completed and accepted in writing by the city engineer.
(Ord. 572 § 1, 2001; Ord. 701 § 1 (Exh. A), 2009; Ord. 857 § 8, 2023)
All utilities shall be underground where feasible. Sanitary sewers and storm drains installed in the street by the subdivider shall be constructed prior to the surfacing of the streets. Stubs for service connections for all underground facilities and sanitary sewers shall be placed to the property line. Private facilities encountered within proposed or newly dedicated right-of-way, including but not limited to private irrigation systems, may be required to be removed, except for crossings, by the city engineer if he determines that their existing location in any way interferes, or could potentially interfere, with the public's full use and interest in lands so dedicated to the public. See also road design standards (EMC Title 19) as adopted.
(Ord. 572 § 1, 2001; Ord. 701 § 1 (Exh. A), 2009; Ord. 857 § 8, 2023)
Maps showing all improvements as-built shall be filed with the city engineer upon completion of the improvements.
(Ord. 572 § 1, 2001; Ord. 701 § 1 (Exh. A), 2009; Ord. 857 § 8, 2023)
(1) 
For all land divisions authorized by this title, the following basic improvements shall be required and implemented concurrent with development of the land division. All land divisions shall provide public streets, water utility service and wastewater utility service to each lot created that is adequate to serve future development at the density authorized by the applicable comprehensive plan and zoning classification and that meets the applicable ordinances, standards of all the Entiat design standards manuals and the Entiat comprehensive plan.
(2) 
All streets and alleys shall have all standing trees, brush, downed timber, and snags cleared and removed from the right-of-way. However, this requirement shall not prohibit the hearing examiner upon recommendation of the administrator, from allowing or requiring at the time of preliminary plat approval that certain plant materials not be removed from the boulevard areas of particular streets.
(3) 
All streets and alleys shall be grubbed by the removal of all large rocks, roots, snags, brush, etc., upon the surface of the ground. All excavation and holes left by such grubbing shall be refilled.
(4) 
All culverts, trestles, or bridges over waterways, draws, or gulches shall conform to the city engineer's specifications for structures of this nature. Where streets or roads of subdivisions connect to, or intersect with, existing roadways, there shall be installed drains of metal or concrete pipe approved by the city engineer.
(5) 
All lot corners, street intersections, boundary angle points, and points in curves in streets shall be marked by three-quarter-inch galvanized iron pipe 24 inches long or equivalent approved by the city engineer. Street monuments shall be set between six inches and one foot below finished street grades, and shall be enclosed in a standard monument case acceptable to the city engineer. See also the road design standards as adopted.
(6) 
All street and alleys shall be graded and surfaced from curb to curb, or roadbed widths specified in Chapter 16.20 EMC, and shall be crowned and surfaced to a depth complying with the standards of the city engineer. See also the road design standards (EMC Title 19) as adopted.
(7) 
All subdivisions shall be served by public, private, or community water supply systems approved by and installed to meet the requirements and standards of the city of Entiat.
(8) 
The proposed subdivision shall be provided with a complete sanitary sewer system designed to serve the subdivision, and to connect the subdivision with the existing trunk sanitary sewer system if feasible from an engineering perspective.
(9) 
Surface drainage from streets and other areas within the proposed subdivision shall be provided with a complete drainage system designed to serve the subdivision and to retain or detain stormwaters on site that discharge at levels that do not exceed historic rates of runoff for the land in question. All drainage analysis shall conform to the Stormwater Management Manual for Eastern Washington, current version and Chapter 19.20 EMC.
(10) 
The capacities and dimensions of all improvements shall be adequate to provide for the future needs of other undeveloped properties in the general vicinity. The city may share in the cost of these improvements to the extent of the difference in cost between the capacities needed to serve the subdivision and the capacities to serve the vicinity.
(11) 
Traffic control and street name signs, as recommended by the city engineer, shall be installed by the subdivider.
(12) 
The subdivider shall provide adequate measures to mitigate for any adverse environmental impacts as identified by the city's environmental and critical area plans and regulations, and the State Environmental Policy Act.
(13) 
The standards and requirements established or referenced by this chapter are minimum requirements. These standards may be increased and additional requirements may be imposed for the purpose of mitigating identified probable significant adverse environmental impacts pursuant to the State Environmental Policy Act, Chapter 43.21C RCW, as now established or hereafter amended. Such additional requirements may include, but shall not be limited to, off-site improvements to any public facility, the dedication and/or improvement of parks and open spaces, and monetary contributions to any city fund established to finance the provision of public services required by the subdivision.
(Ord. 572 § 1, 2001; Ord. 701 § 1 (Exh. A), 2009; Ord. 857 § 8, 2023)
The subdivider shall either install all required improvements and repair any existing streets or other facilities damaged in the development of a subdivision, or execute and file an agreement between himself and the city specifying the period acceptable to the city within which he shall complete all required improvement work to the satisfaction of both the city engineer and the administrator. All work performed shall be guaranteed for a period of two years following completion. The filing of the final plat by the subdivider constitutes the subdivider's acknowledgment that such work is so guaranteed. The subdivider shall set all monuments and lot corner markers to the satisfaction of the city engineer. If the subdivider fails to complete such work within such period, the city may complete the same and recover the full cost and expense thereof from the subdivider or his surety. The agreement shall also provide for inspection of all improvements by the city. Such agreement may also provide:
(1) 
For the construction of all improvements in units.
(2) 
For the extension of time under conditions specified therein.
(3) 
For the termination of the agreement upon the completion of the construction of improvements deemed by the city engineer and administrator to be at least the equivalent of the improvements specified in such agreement and required to be constructed by the subdivider.
(4) 
For progressive remittances to the subdivider for any deposit money which the subdivider may have in lieu of providing a surety bond, as provided in EMC § 16.24.080; providing, however, that no such progress payments shall be made for more than 90 percent of the value of any installation work; and provided, that each installment of work shall be completed to the satisfaction of the city engineer and administrator.
(Ord. 572 § 1, 2001; Ord. 701 § 1 (Exh. A), 2009; Ord. 857 § 8, 2023)
The subdivider shall file with the improvement agreement required in EMC § 16.24.070 a performance bond in an amount deemed sufficient by the city engineer to cover the estimated costs of said improvements, and to cover the estimated costs of setting monuments and lot corner markers that are to be set after the improvements are completed. Upon completion of the improvements, the city engineer shall fix an amount deemed necessary to cover the costs of failure of any of the improvements or work done occurring within two years following completion. Said bond shall be executed by a surety company authorized to transact a surety business in the state of Washington, and shall be approved as to form by the city attorney. In lieu of a faithful performance bond, the subdivider may deposit with the city clerk-treasurer, in the form of cash, bonds, savings deposit books, certificates of deposit, or any other surety acceptable to the city attorney in an amount fixed by the city engineer.
(Ord. 572 § 1, 2001; Ord. 701 § 1 (Exh. A), 2009; Ord. 857 § 8, 2023)
In the event the subdivider shall fail to complete all improvement work in accordance with the provisions of this code and improvement agreement, the city shall complete the same and shall either call upon the surety for reimbursement or appropriate from any cash deposit funds for reimbursement. If the amount of surety bond or cash deposit shall exceed all costs and expenses incurred by the city, it shall release the remainder of such bond or cash deposit, and if the amount of the surety bond or cash deposit is less than the cost of expense incurred by the city, the subdivider shall be liable to the city for such difference.
(Ord. 572 § 1, 2001; Ord. 701 § 1 (Exh. A), 2009; Ord. 857 § 8, 2023)
No progress payments from such deposit or release of surety bond or cash deposit shall be made except upon certification of the city engineer that work covered thereby has been satisfactorily completed. Surety bonds or cash deposits to cover the costs of failure of any improvement or work shall be released by the end of one year after completion of such work or improvements upon certification of the city engineer, if such improvement or work has not failed. In the event of failure during such period of one year following completion, the procedure utilized in EMC § 16.24.090 shall be implemented so as to restore the work so failing.
(Ord. 572 § 1, 2001; Ord. 701 § 1 (Exh. A), 2009; Ord. 857 § 8, 2023)
