§ 8. Required improvements.

A.

Before giving final approval to any subdivision within the city limits, the Planning Commission will require that the following improvements are either (a) constructed and in place, or (b) assured of completion by the deposit with the city of Jamestown of a certified check in an amount sufficient to pay the cost of such improvements. The sufficiency of said amount shall be determined on the basis of estimates submitted by the city engineer. In any event, the party making such deposit shall be held accountable to the city to the extent the amount on deposit with the city is insufficient to defray the actual costs of such improvements. The improvements required shall be:

1.

Water and sewer mains constructed and in place.

2.

Streets and alleys brought to grade.

3.

Graveling upon completion of water and sewer main installation.

4.

Slope protection when necessary.

B-1.

No improvements shall be made unless and until all necessary plans, profiles and specifications therefor shall have been submitted to and approved by the city engineer.

2.

At the time such plans, profiles and specifications are submitted for review, the city engineer shall prepare an estimate of cost for office checking and field inspection of all improvements. The subdivider shall thereupon deposit with the city auditor an amount of money equal to twenty-five per cent of said estimated cost. All work done by the city engineer in connection with checking, computing and correcting such plans for improvements and in connection with field inspection of the construction thereof, shall be charged to such deposit. If, during the progress of the work, it shall appear that twenty-five per-cent of the cost thereof will exceed the amount so deposited, the city engineer shall notify the subdivider of this fact and shall do no further work in connection with such review or field inspection until the subdivider has deposited the additional amount of money necessary to cover twenty-five per cent of the cost of the work.

3.

Upon the completion of the work of checking plans and inspecting the construction of improvements, the city engineer shall forward to the city auditor a statement of the amount of the engineering and inspection costs to be charged against the deposit made by the subdivider. The city auditor shall thereupon refund to the subdivider any unexpended balance of such deposits. If such engineering and inspection charges shall for any reason exceed the amount of the deposits, the city auditor shall collect the balance due and shall issue a statement that such charges have been paid.

4.

Protective measures required on slopes.

(a)

Slope protection measures are required to be performed by a permittee at any time when either of the following situations exist:

(1)

Any portion of the area being excavated is a natural drain area.

(2)

When finished grades are in excess of three percent, or where natural cover has been disturbed.

(b)

For any excavation, made pursuant to this article, where protective slope measures are required, the following shall be used according to the specific excavation being performed.

(1)

Retaining walls of sufficient size and strength to securely retain the soil which such walls are holding, where the slope exceeds a ratio of two to one. Loose laid rip-rap shall not be acceptable.

(2)

Stake sod where the slopes are between the ratios of two to one and four to one.

(3)

Seeding with quick germinating seed where the ratio of the slope is less than four to one.

(4)

Seeding with quick germinating seed over the entire area which has been disturbed in addition to the actual slopes or banks.

(5)

Storm sewer, culverts or other specific drainage facility to be installed where, in the opinion of the city engineer, they are required for protection of the property. Engineer design information shall be provided by the permittee.

5.

Seeding requirements.

(a)

The quick germinating seed required under section 8, paragraph B, subsection 4 shall be of a uniform mixture of approved first quality seed, certified as to purity and germination, and shall be proportioned by weight according to the following formula:

Percent by Weight	Kind of Grass	Percent Purity	Germina- tion Min. Percent
50%	Crested Wheat Grass	93%	85%
25%	Slender Wheat Grass	90%	85%
25%	Western Wheat Grass	90%	85%

 

(b)

The seed shall be sown at the rate of sixteen pounds per acre and sixty pounds of ammonium nitrate. Thirty-three and one-half percent nitrogen per acre shall be spread on the soil prior to seeding or by means of fertilizer attachments on the drill. Ammonium nitrate shall not be mixed with the seed. If seeding is performed before the fifteenth day of July, twenty pounds of oat seed per acre shall be added to the above mixture and if seeding is performed after the fifteenth day of July, thirty pounds of rye seed shall be added to the above mixture per acre.

(c)

If seed of the specified germination cannot be obtained, additional seed shall be used to bring the amount of live seed up to the amount required by specified germination.

6.

Responsibility for germination of grass seed. It shall be the responsibility of a permittee under this article to maintain and water the planted seed until the time as the minimum percent germination has been accomplished. In addition, it shall be the responsibility of the permittee to maintain and water all sodded surfaces until such time as eighty-five percent of the sodded area has successfully resumed growth. The permittee shall be required to reseed or resod any areas in excess of ten square feet which do not successfully germinate or resume growth.

7.

Work to be completed within forty-five days. The seeding, sodding or construction of retaining walls, or construction of culverts, storm sewers or other facilities for drainage, must be completed within forty-five days after work is commenced. It shall be unlawful for any person to leave any excavated area uncompleted beyond the expiration of the time provided in this section.

C.

At the time of filing an application for final approval, the subdivider will submit either (a) a certificate signed by the city engineer that all required improvements are in place, or (b) a certificate signed by the city engineer that plans, specifications, and profiles for such improvements have been filed with and approved by him, and a certificate signed by the city auditor that a certified check or satisfactory performance bond has been posted. Where part of the improvements have been completed, appropriate certification will be filed.
