Section 3. Council's action to provide for a waiver for the request for public water and sewer shall be revoked if the subdivision or individual phases of the subdivision are not complete and accepted by the City within ten (10) years of this action. PASSED BY THE COUNCIL OF THE CITY OF KENAI, ALASKA, this 5th day of June, 2013. R "VCE ATTEST: S Sandra Modigh, City Clerk u "'Villaye with a Past, C# with a Future 210 Fidalgo Avenue, Kenai, Alaska 99611 -7794 �d Telephone: 907 - 283 -7535 / FAX: 907 - 283 -3014 1IIIIi 1992 MEMO: TO: City Council /It FROM: Rick Koch, City Manager DATE: May 29, 2013 SUBJECT: Resolution 2013 -36, Kee's Tern Subdivision, Road Standards The purpose of this correspondence is to provide information to the Council regarding a request from the developer of the above referenced subdivision to vary from the road standard provided for in the Kenai Municipal Code. At the Planning & Zoning Commission meeting of May 22, 2013, the Commission considered a request to waive the requirement for public water and sewer systems in the Subdivision. Administration transmitted a memorandum to the Commission recommending that the code requirements for water and sewer be waived. At the P & Z meeting the developer, during the comment period for the resolution to waive water and sewer, requested that the P & Z Commission also waive the City's code requirement for roadway standards, and instead allow the developer to build to "Borough Standards." The developer made the request directly to the Commission without any discussion with the Administration. Additionally, there was no formal proposal, or detailed alternative to be considered. The developer's consultant testified that there were many minimum standards of roadways that were of a lesser standard than what is required by the City and that the City should therefore allow for a lesser standard of construction. I testified before the Commission and respectfully suggested that they should not consider this undefined, verbal request that was coming before them without any notice, and without a detailed request from the developer with the benefit of administrative review. The Commission agreed with my request and asked the City Manager if it was possible that the developer work with Administration to consider an alternative roadway design. Then, assuming the alternative design was acceptable to the Administration and the developer, could Administration take a request for a variance of the road design directly to the Council at the June 5th Council meeting without the road standard variance having to come back before the P & Z Commission? My short response was, "I'm not sure, but I believe that Council could probably consider this if they wanted to." I also told them that Council's decision could be to send it back to the Commission and request a report as required by KMC 14.10.090 Variations and exceptions. I received the attached Exhibit A) correspondence from the developer's consultant on the afternoon of May 28 h (correspondence is dated May 23rd). I reviewed the proposed road standard and discussed the matter with the Public Works Director. The standard, while probably meeting minimum standards for certain jurisdictions is not acceptable. It will result in increased maintenance costs, and if upgraded to a paved standard in the future, increased construction costs over the standard required in code, or alternatives deemed acceptable by the City. During my discussion with the consultant he informed me that while their proposed standard drawing identifies both paving and crushed aggregate base course it is not the developer's intent to install either of these items. The City responded to the developer's consultant the afternoon of May 28th by transmitting a marked -up version of the developer's proposed standard (Attachment B). The Administration's proposed changes to the developer's submittal was to increase the overall width of the section by two feet, and require the surfacing material to be a minimum of four inches of crushed aggregate base course. The effect of these changes is to provide adequate roadway surface for the future construction of two, twelve foot paved driving lanes, and to install four inches (4 ") of crushed aggregate base course to minimize maintenance of the non -paved roadway. I spoke with the developer's consultant during the late morning of May 29th. I informed him I had a deadline of that day to have materials in the packet for the June 5, 2013 Council meeting and that I needed to know by 2:30 PM if the developer agreed with the City's alternative standard. Further, I informed him if the developer /consultant did not respond there would not be a resolution in the packet addressing a variance for the road standard in Kee's Tern Subdivision, but that Administration would include an informational item to provide a status report to the Council. At this juncture there are three roadway standards that are acceptable to the Administration. They are described as follows: Per KMC 18.10.030. All streets and public ways shall be graded to their full width, as required by the City Manager to the appropriate grade, and shall be surfaced to a minimum of thirty feet (30'), and all major streets shall be surfaced to a minimum width of forty feet (40'). The cross section of construction shall contain non -frost susceptible material to a depth of forty - two inches (42 ") or down to sand, as required by the City Manager, from the grade approved by the City, then there shall be added non -frost susceptible material eighteen inches (18 ") of the normal surface grade of the adjacent lots; or as established by the City Manager, there shall be added thereon gravel approved by the City Manager for a depth of six inches (6 "), so the crown of the finished street shall be not less than twelve inches (12 ") from normal surface grade of the adjacent lots before compaction of the gravel. Such construction shall be subject to inspection and approval by the City Manager, and shall apply with all City standards for construction. (Exhibit C) 2. Alternative #1. A paved standard with two (2), twelve foot (12) driving lanes with one -foot (1') shoulders, over two inches (2 ") of crushed aggregate base course, over a minimum of thirty -six inches (36 ") of non -frost susceptible material as approved by the City Manager. (Exhibit D) 3. Alternative #2. The proposed standard submitted by the developer (Exhibit B) including modifications proposed by the City. A twenty -six foot (26') non - paved surface consisting of four inches (4 ") of crushed aggregate base course over six inches (6 ") of two inch minus ( -2 ") gravel sub -base, over thirty -two inches (32 ") of non -frost susceptible borrow, or non -frost susceptible native material. Absent an agreement between the Administration and the developer for a roadway standard in Kee's Tern Subdivision, and assuming the developer will come before Council at the June 5th meeting, requesting Council action on this issue, Administration recommends the following *: 1. Council approve a variance of the roadway standards to include any of the three alternative designs acceptable to the Administration and described it this document. 2. That Council does not consider any other alternative designs, other than those acceptable to the Administration, without requiring the developer to follow the process for provided for in code, KMC 14.10.090 * The City Clerk and /or City Attorney should provide guidance about whether Council action on this issue meets public notice requirements. Without getting into a long philosophical discussion on road standards, and there are an almost limitless number of standards, it's important to recognize the City, within reason, has the ability to set its own standards, and the City has done that in Chapter 18.10 of the Kenai Municipal Code. Could the code provide more detailed guidance, yes, but the code requirements as written, do not result in the construction of sub - standard, or gold - plated roadways. The Kenai Peninsula Borough has adopted different standards than the City of Kenai, for residential subdivisions some of the Borough standards result in a roadway of lesser quality being constructed. This doesn't mean they are substandard, only that they meet a lower standard. Without researching the standards employed by Municipalities and Boroughs throughout the State I am aware that the standards for residential roadway construction employed by the Municipality of Anchorage, Matanuska Susitna Borough, and the City of Palmer, exceed the standards of the Kenai Peninsula Borough, as does the City of Kenai. The City prides itself in actively improving the overall standard of quality of the roadways for which the City is responsible. Over the past five years the City has improved and paved over three miles of gravel surfaced roads. Some of these newly paved roads are to a lesser standard than two, twelve foot driving lanes because that is what we had to work with. Oftentimes the scope of work for existing roadway improvements is based on a balance between the cost residents are willing to pay through an LID process and the real /perceived value of the improvements to the property owners. Just because a few newly paved residential roadways have been paved to a narrower standard that shouldn't be confused with a narrower roadway width being acceptable in a new subdivision.

SUBJECT: PZ 13 -25, Kee's Tern Subdivision, Street design variance request DATE: May 23, 2013 On behalf of Ed and Kathy Martin, owners of the subject property, I am submitting the following request for a variance from the current requirements of KMC 14.10.080 and 18.10.030, specifically a variance from the required 30 foot gravel street width to a lesser width of 26 feet. RELEVENT CONDITIONS: Kee's Tern Subdivision is located across the Kenai Spur Road from Thompson Park Subdivision and fronts on the north side of North Dogwood Road. The parcel contains 35 acres and is proposed to be subdivided into 24 lots of 1.0 to 1.3 acres in size. The lots will be served by three minor low volume streets serving 6 to 10 lots each with an estimated maximum daily traffic volume of about 50. The Streets were cleared and excavated to a sand subgrade years ago but never completed. A copy of the preliminary plat is attached as Attachment One. CITY CODE: Current code, for minor streets such as these, requires a minimum of a 30 foot graded surface, topped with an approved 6 inch gravel surface course providing a finish centerline grade within 12 inches of adjacent property and graded to drain with 24 inch deep ditches. The City Manager provided the Martins a sketch of a typical street section that would conform to the current code and is attached as Attachment Two. DISCUSSION: More comprehensive design standards are available that provide dimensional requirements based on variable traffic conditions. Being familiar with the various standards applied by the Kenai Peninsula Borough for various categories of roads in rural settings such as this, the Martin's requested me to develop a recommendation for an appropriate street section based on accepted Industry Standards we regularly use for street and highway design and construction. My evaluation is not based on the roughly 15 % saved in construction but solely by the merits of expected traffic conditions, street geometrics and safety. Based on my evaluation a 26 foot gravel surfaced road with a properly designed section depth would provide a safe and maintainable travel way that could be upgraded to a paved surface of adequate width in the future. My recommended section drawing is attached as Attachment Three. Philip W. Bryson PE (retired) elan N. Corthell PE ^ Frank W. Wince PE (Deceased)) Mark E. Blanning PE �/�I E. Casey Madden PE EXHI817 �oA @ of ANALYSIS and JUSTIFICATION: As mentioned above the Kenai Peninsula Borough Title 14, Chapter 14.06, Road Construction Standards, provides standards based on the lot density served by the road. In this case Kee's Tern Subdivision streets, serving 10 and less lots each, would be classified as Category I streets requiring a total gravel width of 20 feet or, if paved, a paved width of 20 feet with 2 foot shoulders. The street widths increase in 2 foot increments as the lot density increases. The Borough standards go on to require stripping of organics within 4 feet of grade, specifications for sub base and base material and section depths as well as for maximum horizontal and vertical alignments. The American Association of State Highway and Transportation Officials ( AASHTO) provides what is universally accepted as the industry standards for design of all public transportation systems. AASHTO bases its design standards on designations such as_ Local, Urban, Rural, Collector, and Arterial as well as Average Daily Traffic counts (ADT), Design Speeds, and the type of terrain in the area. In this case Kee's Tern Subdivision streets would be designated Local Rural with a ADT range of 50 -250 vehicles per day and would require, like the Borough, a paved travel way width of 20 feet with 2 foot shoulders. Section depth is not specified as it is site specific designed based on several design methods involving soil mechanics and applied ADT and heavy truck loading. AASHTO goes on to provide additional guidance for providing safe sight distance by limiting horizontal and vertical alignments, clear zones, and the additional requirements that may be needed for on street parking or larger vehicle use. As both the Borough and AASHTO paved widths require a 24 foot finished surface, including pavement and shoulders, constructing the street now, to gravel sub base grade would require a width of 26 feet as shown on Attachment Three. Over the past 35 years Wince Corthell Bryson has designed many of the City's Streets utilizing the City and AASHTO standards. During the development of the design with the City the designation of minor or major was established and if on street parking was going to require additional width such as the 30 and 40 foot requirement accommodates. Following is a table of some of the Kenai Streets we have designed over the past 35 years showing their City ( AASHTO) designations and constructed sub base gravel width.

Casey Madden PE 2 or I believe this analysis provides the justification and recommend the lesser width based on the standards set by quantifiable design variables such as lot density and/or traffic volume as well as the conditions that are provided by the existing City streets listed above. We appreciate the Administrations assistance and the Councils consideration in this matter and would also like to take the opportunity to encourage the City to consider developing comprehensive design and construction standards that take into consideration quantifiable and qualitative parameters.

I went to the City of Kenai's website & printed them off so that we could use them as a guideline as we go through this process of getting our plat approved by the City and go through the construction phases of our development. I have done some comparison research and have found that these codes are quite old and in need of upgrading to bring them up to industry standards. This is probably why it was originally suggested/recommended we construct roads to Municipality of Anchorage Standard Specifications (MASS 2009). We objected to this because MASS 2009 was never formally adopted by the City of Kenai, and has codes specific to Municipality of Anchorage communities. The Municipality of Anchorage has a higher density of people /traffic, water, sewer, electricity and natural gas utilities are more readily available, and a higher rate of existing roads are paved that might be used to access a new development within their municipality. In short, they don't reflect communities or conditions in our Borough. Please notice item No. 4 under "Notes" on our preliminary plat for KEE's Tern Subdivision.

As the plat states, it has been our intention all along, and we still desire to, build the roads in KEE's Tern Subdivision up to Kenai Peninsula Borough Standards as their applicable codes are more in line with current industry standards (American Association of State Highway and Transportation Officials (AASHTO) design manual entitled "A Policy on Geometric Design of Highways and Street "). I am therefore notifying the City of Kenai that we intend to ask to build the roads in KEE's Tern Subdivision to Kenai Peninsula Borough Standards. I believe this can be accomplished during the "Installment Agreement " phase between us & the City. I do not believe I have to actually request a waiver from the City Planning and Zoning Commission; they can only "recommend" a waiver correct? I realize that the City of Kenai has not adopted Kenai Peninsula Borough Codes. I am suggesting that the City of Kenai and Kathleen Martin, property owner of record on the preliminary plat for KEE's Tern Subdivision, can come to an agreement that the roads in KEE's Tern Subdivision will be built to meet Kenai Peninsula Borough Codes. We can meet to review said codes, and agree to what will be required of us. I'm sure the City Attorney can provide both parties appropriate terminology for the Installment Agreement. I feel this is the best solution to update road standards at this time. Kenai Peninsula Borough Codes have been designed to regulate areas within its confines, and when necessary to mention conditions specific to certain communities it does so. I thank you for your time and careful consideration in this matter. Sincerely, Kathleen A.

It is my understanding the developer /petitioner is requesting that the requirements for the installation of an approved public water supply in subdivisions of ten(10) or more lots per KMC 14.10.080(e), and the installation of sanitary sewer lines to serve each lot when sanitary sewers are available for connection by the subdivider per KMC 14.10.080(f), be waived, varied, or modified by the City Council after a report by the Planning & Zoning Commission (P & Z). Further, it is my understanding that the developer is not requesting a waiver, variance, or modification from any other requirements contained in the Kenai Municipal Code. Request #1, To eliminate the requirement for a public water supply Relevant Conditions: An existing water transmission main, available for connection by the developer is located approximately 250 lineal feet from the subdivision. The subdivision is comprised of lots in excess of 40,000 square feet in size, and meets the Alaska Department of Environmental Conservation (ADEC) minimum lot size requirements for on -site water and sewer systems. Analysis: As stated above the proposed subdivision does not require a public water supply to meet ADEC regulations. I considered the following criteria: 1. Fire protection. While fire protection of any homes /structures would be enhanced by a public water supply which included fire hydrants, the existing homes /structures in near proximity to the proposed subdivision are not served by public water systems and receive fire protection from the Kenai Fire Department through the use of tanker trucks. 2. Will there be future development(s) in the proximity of the proposed subdivision that will need to be connected to an extension of the public water system? Probably not, there is very little developable property to the west, the proposed subdivision is bounded by the Beaver Creek Drainage to the north, and much of the property to the south has already been developed as single family residences having on -site water and sewer systems. Recommendation: Administration recommends that P & Z's report to Council include a recommendation that the code requirement for a public water supply be waived. Request #2, To eliminate the requirement for installation of sanitary sewer lines to serve each lot and to connect to a sanitary sewer collector if located within 1,500 feet of the subdivider's nearest lot line. Relevant Conditions: A sanitary sewer collector is located approximately 400 lineal feet from the subdivision. The sewer collector is located on the opposite side of the Kenai Spur Highway. The cost of boring under the Kenai Spur Highway is estimated to be at least $50,000 and could be greater given the depth of bury. Analysis: Given the lot sizes the proposed subdivision does not require connection to a public sanitary sewer system to meet ADEC regulations. I considered the following criteria: 1. The cost of connecting to the City's sanitary sewer on the opposite side of the Kenai Spur Highway. The cost for the connection and a system to serve this large -lot subdivision is prohibitive and may well result in the development being financially unfeasible. Soils conditions being conducive to on -site sewer systems. There is no reason to assume the soil conditions will not support on -site systems. There are many on -site systems in operation in the immediate vicinity. 3. Health issues. There are no known health issues, such as contamination of existing wells and /or groundwater. Recommendation: Administration recommends that P & Z's report to Council recommends that the code requirement for a sanitary sewer connection be waived. Subdivision Road Standards While not requested by the developer, the Administration requests that P & Z include an acceptable alternative roadway design in its report to the City Council requesting that a variance be approved by Council if the developer wants to construct the alternative design rather than what is required in KMC 14.10.080(c) and KMC 18.10.030. Attached as Exhibit "A" is a sketch of the roadway standard required in municipal code (sheet 1) and a proposed alternative standard (sheet 2). The developer will not be required to construct to the alternative standard, rather it is simply for consideration by the developer.

The property owner is requesting the Planning Commission grant exceptions to three (3) of the recommendations that were approved under PZ13 -01 (see attached PZ13 -01 Resolution): "Grant an exception to KMC 14.10.080(e) (Public Water System) and (0 (Sanitary Sewer Service)." The Planning Commission cannot grant this exception, but they can make a recommendation to the Kenai City Council to waive the requirement. 2. "a.

The City of Kenai has of code into our municipal code, d, Streets will require a minimum 24 -foot paved surface, with 2 -foot shoulders and approved excavation and backfill." This requirement is not in our code. Roads must be built in compliance with Kenai Municipal Code 14.10.080(c). It is recommended the Commission make findings to the waiver of the utility exceptions. The Commission can amend the requirement that the streets must be built to the requirements of KMC 14.10.080(c). Unless the Commission makes additional exceptions, the remaining requirements must still be met. m WINCE — CORTHELL — BRYSON Consulting Engineers Box 1041 Kenai, Alaska 99611 Phone 907 - 283 -4672 Fax 907 - 283 -4676 E -Mail cmaddenawcbalaska.com TO: City Administration and Council FROM: Casey Madden, P.E. SUBJECT: PZ 13 -25, Kee's Tern Subdivision, Street design variance request DATE: May 23, 2013 On behalf of Ed and Kathy Martin, owners of the subject property, I am submitting the following request for a variance from the current requirements of KMC 14.10.080 and 18.10.030, specifically a variance from the required 30 foot gravel street width to a lesser width of 26 feet. RELEVENT CONDITIONS: Kee's Tern Subdivision is located across the Kenai Spur Road from Thompson Park Subdivision and fronts on the north side of North Dogwood Road. The parcel contains 35 acres and is proposed to be subdivided into 24 lots of 1.0 to 1.3 acres in size. The lots will be served by three minor low volume streets serving 6 to 10 lots each with an estimated maximum daily traffic volume of about 50. The Streets were cleared and excavated to a sand subgrade years ago but never completed. A copy of the preliminary plat is attached as Attachment One. CITY CODE: Current code, for minor streets such as these, requires a minimum of a 30 foot graded surface, topped with an approved 6 inch gravel surface course providing a finish centerline grade within 12 inches of adjacent property and graded to drain with 24 inch deep ditches. The City Manager provided the Martins a sketch of a typical street section that would conform to the current code and is attached as Attachment Two. DISCUSSION: More comprehensive design standards are available that provide dimensional requirements based on variable traffic conditions. Being familiar with the various standards applied by the Kenai Peninsula Borough for various categories of roads in rural settings such as this, the Martin's requested me to develop a recommendation for an appropriate street section based on accepted Industry Standards we regularly use for street and highway design and construction. My evaluation is not based on the roughly 15 % saved in construction but solely by the merits of expected traffic conditions, street geometries and safety. Based on my evaluation a 26 foot gravel surfaced road with a properly designed section depth would provide a safe and maintainable travel way that could be upgraded to a paved surface of adequate width in the future. My recommended section drawing is attached as Attachment Three. Philip W. Bryson PE (retired) Alan N. Corthell PE Frank W. Wince PE (Deceased)) Mark E. Blanning PE E. Casey Madden PE ANALYSIS and JUSTIFICATION: As mentioned above the Kenai Peninsula Borough Title 14, Chapter 14.06, Road Construction Standards, provides standards based on the lot density served by the road. hi this case Kee's Tern Subdivision streets, serving 10 and less lots each, would be classified as Category I streets requiring a total gravel width of 20 feet or, if paved, a paved width of 20 feet with 2 foot shoulders. The street widths increase in 2 foot increments as the lot density increases. The Borough standards go on to require stripping of organics within 4 feet of grade, specifications for sub base and base material and section depths as well as for maximum horizontal and vertical alignments. The American Association of State Highway and Transportation Officials ( AASHTO) provides what is universally accepted as the industry standards for design of all public transportation systems. AASHTO bases its design standards on designations such as, Local, Urban, Rural, Collector, and Arterial as well as Average Daily Traffic counts (ADT), Design Speeds, and the type of terrain in the area. In this case Kee's Tern Subdivision streets would be designated Local Rural with a ADT range of 50 -250 vehicles per day and would require, like the Borough, a paved travel way width of 20 feet with 2 foot shoulders. Section depth is not specified as it is site specific designed based on several design methods involving soil mechanics and applied ADT and heavy truck loading. AASHTO goes on to provide additional guidance for providing safe sight distance by limiting horizontal and vertical alignments, clear zones, and the additional requirements that may be needed for on street parking or larger vehicle use. As both the Borough and AASHTO paved widths require a 24 foot finished surface, including pavement and shoulders, constructing the street now, to gravel sub base grade would require a width of 26 feet as shown on Attachment Three. Over the past 35 years Wince Corthell Bryson has designed many of the City's Streets utilizing the City and AASHTO standards. During the development of the design with the City the designation of minor or major was established and if on street parking was going to require additional width such as the 30 and 40 foot requirement accommodates. Following is a table of some of the Kenai Streets we have designed over the past 35 years showing their City ( AASHTO) designations and constructed sub base gravel width.

Bryson PE (retired) Alan N. Corthell PE Frank W. Wince PE (Deceased)) Mark E. Blanning PE E. Casey Madden PE I believe this analysis provides the justification and recommend the lesser width based on the standards set by quantifiable design variables such as lot density and/or traffic volume as well as the conditions that are provided by the existing City streets listed above. We appreciate the Administrations assistance and the Councils consideration in this matter and would also like to take the opportunity to encourage the City to consider developing comprehensive design and construction standards that take into consideration quantifiable and qualitative parameters.
