6A • December 11, 2015 • Seaside Signal • seasidesignal.com Seaside ready to take a fresh look at grading dunes City partners with CREST to create new guidelines By Katherine Lacaze Seaside Signal Seaside is receiving some help from a local task force to keep its dunes healthy and safe. The City Council ap- proved an agreement with the Columbia River Estuary Study Taskforce to update the city’s foredune manage- ment plan last month. The Astoria-based task force is a community organization that specializes in environ- mental and coastal planning. The update could lead to more trees, plantings and dune-grading activities. Many of these are prohibited on Seaside beaches because of state guidelines. To conform with state rules, the city needs to up- date its plan and seek an ex- ception to the statewide plan- ning goal dealing with dunes and beaches, known as Goal 18. The exception — which allowed property owners in different areas along the beach to grade their sections below goal limits — expired several years ago, according to Planning Director Kevin Cupples. The task force will pro- vide its services for approx- imately $12,100, or a rate of $60 per hour. Additional- ly, the city plans to contract with an expert in coastal geology to provide techni- cal oversight. The need for updates The city is considering amendments to provide for dune grading in selected ar- eas to depths between the base Àood elevation and four feet above base Àood elevation. Currently, any dune grading below four feet above the base Àood el- evation requires the city to obtain an exception to Goal 18, according to Cupples. In the past, the city had an exception to Goal 18 to grade the dunes from Broadway to north of 12th Avenue. At that time, a group of property owners along the Prom from about Third to 10th avenues received approval to grade the dunes near their homes and businesses. They contin- ued to do maintenance grad- ing after the initial project. “Now we’re to a point where trying to continue maintenance grading is vio- lating the goal, so we’ve got to reauthorize the exception or you can’t grade down to the levels that you were al- lowed to before,” Cupples explained. The Land Conservation and Development Commis- sion will have to approve the exception. The statewide planning goal set the level at four feet above the base Àood elevation as “a safety measure,” Cupples said. “It’s a matter of protecting the inland areas from potential Àooding.” In order to get an excep- tion approved, the city needs to justify allowing grading below that level and demon- strate that it won’t have a negative affect on safety in those areas. What Cupples believes will help is that portions of the Seaside beach are under- laid by cobblestone, which is added protection. create an urban forest down there,” Cupples said. “It’s supposed to have kind of a semi-open look.” With so many trees grow- ing in the area, the dense vegetation offers an oppor- tunity for people to camp overnight, which is against city ordinance and creates a potential ¿re risk. Right now, the city al- lows certain actions. “When there is an un- healthy spacing of trees, we’ve allowed it to be tak- en out, but it’s not well ex- plained in the plan that you should be doing that,” Cup- ples said. “That’s what we want to be clari¿ed.” CREST to provide scope, goal-setting R.J. MARX/THE DAILY ASTORIAN A foredune grading plan is being developed in Seaside. Here, the dunes just north of 12th Avenue. “Even if you eroded part of your sand away, you still have cobble beach protec- tion, which tends to break up waves pretty well,” Cupples said. Changes in the future The city wants the man- agement plan amendments to make grading elevations “dynamic,” so they respond to future changes in the base Àood elevation. )or instance, if the base Àood elevation is lowered in the future, the city’s allowed grading elevation would lower automatically to al- low for enhanced grading activities, Cupples said. Likewise, if the base Àood elevation is heightened, the allowed grading elevations also would heighten, en- suring “the allowed grad- ing elevations would not compromise Àood hazard protection,” according to a memorandum presented at the City Council meeting. Rather than including spe- ci¿c grading depths in the plan and exception based on the current levels, Cupples Commission mulls growth boundary options Growth from Page 1A satisfy the city’s projected population in 20 years, an analysis showed about 208 acres. “We can back our 20-year demand down to where it would be a 14-year demand and go with that,” City Plan- ner Kevin Cupples said. This would show the state that the city is consid- ering public input and tes- timony, he said. “And then we can re-evaluate that sev- en years down the line, or 10 years down the line.” Dispersing the impact Since the commission started considering the ex- pansion, members focused on the Southeast Hills site, to the south and east of Spruce Drive and Wahanna Road. They determined that area alone could provide enough developable land to meet the city’s 20-year land supply needs. Landowners in that area, which currently is part of unincorporated Clatsop County, have questioned the expansion and how it would impact property tax evaluations, traf¿c patterns, infrastructure and lifestyles. Two other sites, earlier deemed less desirable than the Southeast Hills site, are back on the table and could help disperse the impact of an Urban Growth Bound- ary expansion. The ¿rst op- tion is the Lewis and Clark Hills site, north of Lewis and Clark Road, which could provide about 23 acres of developable land. Second is the North Hills site, east of North Wahanna Road with potential access from Shore Terrace and Ocean Avenue, which could provide about 34 acres of developable land. Hanson suggested the city take a two-step approach, ¿rst submitting a primary application to satisfy the 14- year land-needs analysis, and keeping the other options “on the books” to make an- other expansion request at a later date, if necessary. Commissioners support- ed the more conservative approach but suggested, rather than taking the ini- tial 141 acres entirely from the Southeast Hills site, combining the Lewis and Clark Hills site, the North Hills site and a portion of the Southeast Hills site, to more evenly distribute the impact. “I want to bring in those other two sites and cut back on the amount we bring in from the Southeast site, be- cause that’s where all the opposition is,” Commis- sioner Richard Ridout said. “Whether we develop low- land or highland, that is the next thing to be decided.” Meeting state planning goals The city started looking at a potential Urban Growth Boundary expansion in or- der to address state guide- lines regarding long-term planning for population growth and urbanization. Those guidelines current- ly ask municipalities to demonstrate a 20-year sup- ply of developable land. The state is revamping and updating those guide- lines to suggest a 14-year time frame instead to help streamline the process and make it simpler for small- er municipalities, Hanson said. Taking a conservative approach to the potential expansion would actual- ly align Seaside with the changes the state is consid- ering, and also address the concern of citizens in the proposed boundary expan- sion area who suggested the city “overshot what our need is,” Cupples added.

With the future uncertain, he favors planning for a shorter time frame. “Having maybe just a triÀe less uncertainty makes more sense to me,” he said. “If we’re going way out, we could be way over, we could be way under. We can always revisit it. We always have an option to do that.” Commissioner Tom Horning agreed, adding, “the 14-year look is a much more tangible situation.” Cleaning up the boundaries At the request of Seaside resident John Dunzer, the city and consultants ana- lyzed another site, near the Cove in southwest Seaside, to see what it could offer in terms of developable land. Because the area is func- tionally “a long dead-end road,” with very limited ac- cess, Hanson said he does not believe the site is opti- mal for inclusion into the Urban Growth Boundary expansion request. It would only provide about 4 acres suitable for development. However, in looking at the area, the city realized its current zoning maps do not match Clatsop Coun- ty’s maps in terms of where Seaside’s existing bound- ary sits. The county’s map recognizing Seaside’s Ur- ban Growth Boundary includes a few areas not shown on the city’s map, and vice versa. If nothing else, Cupples said, the city should use this opportunity to clarify the actual south- west boundary. “When this is all said and done, even if you don’t change anything down in that area, what I would like to do is match what the county has,” he said. “Then, if there are lands the county is saying are not in, I want to make sure those lands do get in, because they have historically been in the Ur- ban Growth Boundary the city recognized.” said, “You want to be able to say, ‘No, if that level goes down, then the grading level will go down along with it.’” Managing vegetation The city plans to clarify what vegetation manage- ment options are allowed in different beach areas. Some vegetation management oc- curs in the southern region of the beach, but the plan did not anticipate the amount of tree growth in that area. The plan needs to specify that the city is “not trying to Kevin Cupples said the city’s Planning Department does not have the staff and resources needed to focus on the process of updating the foredune management plan, at this time. CREST is a council of local govern- ments, of which Seaside is a part, that helps communities with land-use planning, Di- rector Denise Lofman said. She said it is important to work with the state during the process “to make sure whatever we are creating for Seaside can be approved at the state level, she said. “The state is really interested in making sure properties are protected in addition to dunes being able to be managed.” Public hearings on the amendments will be June to August. Seaside City Council must approve the amendments before the updated plans and justi¿- cations are sent to the Land Conservation and Develop- ment Commission.
