Carey Don Wickstrom M. G. Welch Jim Hansen R. Scalzo Gary Gill J. Scalzo Tom Brubaker Gary Moore Carol Morris Bruce Rayburn Ed White Doug Sutherland Tony McCarthy Frank Hansen Lloyd Tomlinson L.I.D. 338 - Request for Exemption from Monthly Seger Charge Mr. Tomlinson stated he was not opposed to the LID. However, he has recently reworked his septic system at a considerable cost. He stated he would like to be able to recover his cost and suggested he be exempted from the monthly sewer charge until he connects to the sewer or at least for a period of 15 years. Tom Brubaker stated that statutory law requires that once the system is built, the property owners must connect or pay a penalty and that is the reason for the monthly charge. White asked if that meant we could not waive the fee. Brubaker stated he did not think so on an individual basis as that would constitute preferential treatment. We could perhaps pass an area-wide ordinance amending our penalty structure. White asked if staff could review the impact if such an ordinance were adopted and bring the information to them at the next meeting. Mr. Tomlinson suggested the law could be written in such a way that it addressed only those who had spent money on their septic systems within a recent time period. Drainage Problem, S.E. 244th Street, William Carey Mr. Carey, 11236 S.E. 244th, between 116th and 112th, introduced two of his neighbors who have been living in the area for many years. Mr. Carey distributed a letter to the Committee describing the drainage problems and presenting proposed solutions. The drainage problems identified by Mr. Carey are an inadequate drainage system west of 112th Avenue S.E. between S.E. 240th Street and S.E. 244th Street and excess runoff from the new Fire Station located on 116th Avenue S.E. Mr. Carey read from his letter describing his observations_ of the construction that has taken Public Works Committee May 7, 1991 Page 2 place recently and their proposed effects on the drainage in the area. Mr. Carey stated that he does not have any immediate plans for developing the property but may in the future and until the drainage problems are corrected he would have difficulty doing that. White asked if the problems have gotten worse over the past four or five years. Mr. Carey said they have gotten progressively worse. Wickstrom stated that the drainage system within the Benson Shopping Center on the north side of 104th is privately owned and is undersized. We are developing plans for upgrading the system from 104th to S.E. 236th. White asked why we were issuing permits and allowing construction without considering the runoff of the development. Wickstrom stated we do require on-site detention. Recent studies on the Lagoon, Mill Creek Analysis and Garrison Creek Basin are giving us better information to calculate storage. We are finding our drainage standards need to be updated. Gill stated we are working on those standards now and he advised the Committee they should be aware that new standards could affect the developers extensively as far as the amount of land required for on-site detention and preservation of low wet areas. We anticipate the standards being completed later this year. Gill stated that we did not allow the new construction to block the drainage flow. Other factors taking place at the same time are the extremely severe storms that we have had recently. White stated he was concerned that we are creating wetlands and are asking individuals to pick up the costs because they have lost the use of their land. Gill responded that these areas were low and wet to begin with. White asked if we could have something back to the Committee by August 1. Mr. Carey asked that the letter to Mr. Gill and the letter he distributed today be made a part of the record and that he receive a response. Orr asked if the new construction pays for their drainage impacts. It was determined that their drainage utility bill is based upon the amount of impervious surface. L. I.D. 339 - Drainage Issue Mr. Moore, 836 Hilltop Avenue, stated that the septic services in the Hilltop area were affected by the underground water, water table level and flooding of their properties caused by the building above them and the drainage system developed for that development. They did not have a problem before the development. It appears that some culverts have been installed that change the direction of the drainage. He described underground water coming up at the end of his asphalt. It was clarified that Mr. Moore was not opposing the LID but concerned about the drainage. Wickstrom explained the drainage system for Lavender Hills and that the homes have roof drains which then infiltrates into the ground water. Wickstrom stated we have looked at installation of an infiltration drain east Public Works Committee May 7 , 1991 Page 3 of Hilltop which would require acquisition of easements. Wickstrom explained other options that are being reviewed. It was determined that staff would bring some recommendations back to the Committee at their June 4 meeting. Request from SeaTac for Extension of Sewer Service Doug Sutherland, City Manager for SeaTac, reviewed the history of the request. SeaTac has been requested to provide sewer service to properties in the vicinity of 212th and 42nd. The area was originally in the Kent sphere of interest for sewer service. In earlier discussions, Kent has indicated they do not want to extend their sewer beyond the City limits in that area. SeaTac has met with Tukwila and another sewer district about sewer service for this property. It appears that the only way service can reasonably be provided is to enter into an interlocal agreement with the City of Kent to allow the City of SeaTac to construct a sewer line to connect into the Metro line on West Valley. Sutherland continued that the City of SeaTac would form a sewer utility to provide sewer service to these properties. He addressed the concerns of zoning and potential development of those properties west of the Green River and within the City indicating those concerns would be met as the line would be owned by SeaTac and they would not be serving properties within Kent. Dowell asked where the connection point would be. Wickstrom responded it would be at 212th on the east side of the river. Jim Hansen stated that about a year ago a similar issue was brought up to Council at a retreat. At that time it was fairly unanimous that we would not extend services across the river. He stated he felt a City policy or direction from Council was needed so these types of requests can be addressed. White stated he would not have a problem extending if all our concerns could be addressed. Leona Orr concurred with that. It was determined that staff would review the issue. Wickstrom stated he would like to have full Council direction before he devotes staff time to the review. Wickstrom indicated for Dowell that technically this would be a sewer extension by SeaTac and would be franchised through the Kent's right of way. White and Orr stated they felt this was a different situation that what is addressed by the moratorium on extending services beyond the City limits. Orr moved that staff develop information on the ideas discussed and bring it before the Committee and Council. Hansen clarified that this would only be a cursory review in order to get direction from the Council. Dowell added that we should have some idea of how much multifamily development might take place in the area and the impact on Kent. This will be brought back before the Committee in about a month. The Committee unanimously approved the motion. S1 e i Public Works Committee May 7, 1991 Page 4 Manganese Water Treatment Facility After discussion, the Committee unanimously recommended approval to transfer $900, 000 from the unencumbered water fund and award of the project. City Shops Equipment Wash Rack After discussion, the Committee unanimously recommended to transfer $17, 000 from the equipment rental fund and to award the project. Hazardous Waste Plan Implementation and Solid Wastg Rates Wickstrom indicated this was informational to alert the Committee there possibly could be some garbage utility rate proposals coming before them soon relating to implementation of the hazardous waste plan. Effective July 1, the haulers will be assessed the fees which they will have to absorb or pass on to the customers. Another issue to affect the garbage rate is the increase in tipping fees we are anticipating to be effective January 1, 1992. Budget Review Wickstrom informed the Committee that the meeting on July 16 has been dedicated to the review of the Public Works 1992 budget requests. It was determined that the Committee would meet at 1: 15 that day. Water Pressure - Cambridge Area Mr. Steinberg related that he has noticed a decrease in his water pressure since January. He became more acutely aware of it when he was getting his sprinkler system ready for the upcoming summer. He checked all the valves and had the company that installed the system for him come out. Wickstrom and Gill advised the Committee that we have the Cambridge tank out of service for painting. Mr. Steinberg said he felt the customers should have been notified and wondered when the tank was going to be put back on-line. Responding to Dowell, Wickstrom said that we do typically notify property owners in the area before any construction project. The Committee asked staff to check it out and let Mr. Steinberg know when the system will be back on-line. 4 Public Works Committee May 7, 1991 Page 5 Revision of Moratorium on Extending Utility Service Outside City Limits White presented a revision to the previously adopted policy. He proposed revising Item C to read "the owners of the property which will receive the water or sewer service shall actively petition for annexation of the property to the City of Kent and give notice of intent to annex at the time their property is included within an area that is being considered for annexation by the City of Kent. " White explained this would allow extension of services if the property is actively pursuing annexation. Orr questioned whether this actually guaranteed that the annexation would take place. The Boundary Review Board could deny the annexation and we would have already extended our utility services. Morris stated it could happen if the County's interim urban designated growth areas are somehow not upheld or if they change them. Orr expressed concerns that this would allow development by County standards in the County without the City having any say, no control over traffic mitigation and those type of issues. Wickstrom added that if we extend utility service to developments outside the City limits we do require them to execute a traffic mitigation agreement and they pay cash up front for each parcel they develop. The development- can not exceed the land uses identified in our comp plan. After further discussion, it was determined this would be directed to the Planning Committee before bringing it to the Council. . ^ ���� �� May 7. 1991 To: City of Kent, Public Works Committee REFERENCE: Letter dated April 25, 1991, W. J. Carey to Mr. Gary Sill , SUBJECT: Drainage Problem. The following is submitted for your information and consideration regarding Agenda #3. PROBLEM: ( 1 ) Inadequate drainage system West of 112th Ave. BE (when completed) between BE 240th St. and BE 244 St. Because of this problem, after heavy winter storms, the runoff water backs up on the proper- ties listed below. (2) The excess runoff from the new Fire Station facilities located on 116th BE. PROPERTIES AFFECTED: The back portion of Christensen/ Vigoren five acres located at 11208 BE 244th St. The back portion of the Welch' s five acres located at 11223 BE 240th St. The back portion of Carey' s five acres located at 11236 BE 244th St. Portion of other properties located West of 112th BE and laying along the drainage ditch. SOLUTION PROBLEM 1 : Improve the existing drainage system so that it can handle the increasing runoff, or build a new system that is capable of handling the runoff. ` SOLUTION PROBLEM 2: Install an adequate retention pond at the existing facility to reduce the rate of runoff. DISCUSSION: The existing drainage system West of 112th BE (when completed) is not adequate to handle the runoff flowing into this natural drainage basin . The backup starts behind the Old Orchard Shopping Center on 104th BE, and progresses East to the properties noted above. Some of the past actions and/or conditions that may have caused this backup are as follows: 1 . When the site was prepared for the building of the East Hill Storage facility on BE 240th the contractor moved hundreds of yards of soil from the front of the property to the rear qf. the property. This created a mound of earth approximately 15 to 20 feet high on the South end of the properLy. This fill may have caused the blockage of normal drainage from the site to the Southwest. This condition may ' contribute to the backup behind the Old Orchard Center. 2. When the site was prepared for the building of Highland Creste Apartments on SE 240th, the contractor removed all the top soil from the site and hauled in hundreds of truck loads of fill material . The rear end of the site was filled to a level of 4 to 5 feet along the drainage ditch runing behind the property. This fill may have contributed to the current drainage backup. Prior to the building of the apartments a lot of water would backup on the property. Now it backs up farther East. 3. When the site was prepared for the building of Royal Firs Apartments on SE 240th, the contractor removed thousands of yards of top soil from the site and hauled in hundreds of truck loads of fill material . The rear end of the site was filled to a level of 4 or 5 feet along the drainage ditch running behind the property. This fill may have contributed to the current backup. Prior to the building of the apartments, a lot of water would backup on this property. Now it backs up farther East. 4. When the site was prepared for the building of the Fire Station facility on 118th SE, the contractor removed all the top soil from most of the site and piled it in a mound on the corner ofALth SE and SE 248th. This mound is still there although some of the top soil has been used for landscaping purposes. The area where the mound is now located was previously a low spot where runoff water would stand. The site contractor hauled in hundreds of truck loads of fill material to raise the elevation of the front of the property to road level (116th SE) . The back of the property, where the Shooting Range and Training Tower are now located, prior to site preparation, was a deep hole that acted as a natural retention pond. This area (hole) was also filled with hundreds of truck loads of fill material . I understand that $800,000 was spent on fill material for this site. This fill along with the blacktop of the entire facility has increased the runoff from this facility by approximately 4 to 5 times it was prior to completion of the facility. This runoff impacts and adversely affects the backup of runoff water on the properties noted above. The existing retention system installed at the facility is not adequate to control the runoff . 5. Other conditions that may contribute to the backup problem' are ( 1) plugged drain tile (cement) run under 104th SE from the back of the Orchard Shopping Center to West of SE 236th PI and 104th SE and (2) blockage of drain ditch West of 112th SE ST (when completed ) behind the Highland Crenote and Royal Firs Apartments. These conditions could be corrected by keeping the culvert and drainage ditch open. 6. The accumulative effect of the above action and/or conditions adversely effect the properties noted, and seriously impact the potential usage of these properties. ' � � ,r� | ` . CITY OF KEM' ' APR 3 0 1991 ENGINEERING DEPT.April 25, 1991 Kent City Hall Public Works Dept. 220 Fourth Ave. South Kent, Washington, 98032-5895 ' Attn : Mr. Gary Gill , Chief Engineer Subject: Drainage ProbJem Reference: Telecon of 4/25/1991 between Mr. Randy Brake and W. J . Carey Dear Mr. Gary Bill , The purpose of this letter is to confirm the referenced conversation regarding the subject. The following properties are affected: The back of my five acres located at 11236 BE 244 St, the back of Christenses/ Vigoren five acres at 11208 BE 244 St. and the back of Martin Welch five acres located at 11223 $E 240th. These properties currently are experiencing a serious drainage problem caused by ( 1 ) excess runoff from the new Fire Station located on 116 Ave. BE, and (2) inadequate drainage west of these properties. The first problem is that after a heavy rain the volume of run off from the ditch flowing from the new Fire -Station has increased approximately four to five times since the facility was completed . This of course aggravates the sec- ond problem and causes increased back-up of waters on the above prqperties. Prior to the building of the Fire Station the run off after a heavy rain from the ditch from that property was a slow gentle trickle, now it comes down like a raging river. It would appear that the retention' pond installed in the new facility is completely inadepuate for that size facility considering the acres of blacktop installed. The second problem is that the run off coming into this natural drainage basin cannot flow out in a timely manner because the drainage system to the West, running behind the Royal Firs Apts. The Highland Crest Apts, thru the east Hill Mini Storage and under the Shopping Centers on 104 Ave. BE is not adequate to handle the run off. So what happens is that after every heavy storm run off water backs up on our properties. Mr. Brake advised in the reference conversation that the City was aware of the drainage problem west of these properties and that plans were in the works to correct this drainage problem. He said that one option being considered was to build a huge retention pond East of 112 Ave. BE. Considering all the current and future development in the County, East of 112 Ave. BE whose run off will flow into this drainage basin, we feel that this option would only be a - ` short term solution . In our opinion the only long term solution would be to build an adequate drainage system to the West. The above problems are currently impacting the., use of our properties. It is therefore requested that the City take whatever ac Lion that is necessary to correct these problems. Very Truly Yours. WJC/AC � cc : Don Wickstrom 'Care�` l�- -�' Jim White M. Welch M. Vigoren ^
