好項目啊。 簡介在內

水邊的話會有code to regulate the boundary of building limit, 比如wetland分級，最少要75 feet，多至200ft. 如果湖邊就是shoreline protection regulation to find the buffer. zoning requirement 網上看zonging map即可，但是在水邊大約要subjects to regulations identified in local shoreline master plan. 

需要找consulting company 去與市政打交道。 可以自己到市政問一下，認為有戲可以下offer that subjects to the Feasibility Study - say, 6-month long. During the period you can hire a development company to conduct the conceptual plan, file a pre-application meeting (while submit the conceptual plan so the City staff can comment and bring all the detailed requirements during the meeting).  Based on the comments from the meeting with City Staff, you revise the conceptual plan and see if the land can still afford 50-unit developments.  Your engineer will provide a quick & rough cost estimates on land, permitting, utilities & roads, survey & recording - that gives you the cost per lot.  Or you may talk back with the seller to re-negotiate the price (據說在地產還不是大熱的時候買家還可以與賣家討價還價的）.  Sounds like a SEPA process inevitable in order to obtain the "preliminary" approval.  好項目啊，流口水ing， 我們這裏要天價了。
