All Handouts referred to in these comments canbe accessed at our website: www.edmondswa.govunder City Government / Development Services Department / Engineering Division then scroll down to Handouts: GENERAL 1)Please note, that because there is curb/gutter, you may install concretefor the driveway approach(from the back of curb to the property line) if you choose. 2)Please show the curb cut for the existing driveway and add a note that the curb cut will be removed and replaced. 3)Please add a note to the plans that state the existing utilities will be removed and/or capped under the demolition permit(BLD20150120). WATER 1)It appears that a fire sprinkler system is required for this property. a.Please show the back of the water meter located at the property line (where the water meter is within the right-of-way). b.Please add a note that a 1” meter is to be installed. c.Please label the pipe material and tracer wire. SEWER 1)The proposed plans state ‘prop. connect new 4” side sewer to ex. stub’. The sewer lateral(the portion of sewer from the main to the property line)must be 6”. Therefore, if the lateral is not 6” you will be DATE E-MAILED3/11/2015PAGE (1) City of EdmondsBLD20150119 TH 121 5AVENUE NORTHEDMONDS, WA 98020 • (425) 771-0220 FAX (425) 771-0221 Website: www.ci.edmonds.wa.us PUBLIC WORK DEPARTMENT Planning • Building • Engineering Engineering Plan Review Comments required to install a new connection at the main(romac inserta tee). Once on private property the side sewer may reduce to 4”. 2)If thesewer lateral is 6”, please note if re-using existing sewer lateral the conditionmust be verified by City’s Public Works Dept. Contact Edmonds sewer division, 425-771-0235. If the sewer division finds the lateral inadequate, the sewer lateral cannot bere-used. 3)Show a 6” cleanout at the property line(where the cleanout will be located within the right-of-way). Please add a note that the 6” cleanout at the property line will have a 12” cast iron lamphole cover with ½” hexbolts. STORM 1)It is unclear which LID stormwater management system you are proposing. Please clearly state what system (as written in Handout #E72B) is proposed and size accordingto Handout #E72B. a.If the proposed system deviates from the options provided in the City Handouts, the system will need to be engineered. For instance, if the system proposed is to discharge to detention and then discharge to an infiltration system. The sizing of the detention and infiltration systems will need to be designed by a licensed engineer. If at any time it is unclear if the system has to be designed by an engineer, please don’t hesitateto ask. b.Once a system is proposed the City will continue the review of the stormwater management system. 2)The surface water runoff from the driveway must discharge directly to a catch basin. If the catch basin is to remain as indicated on the proposed plans, please show the how the surface water runoff will discharge to the catch basin and not onto the landscape areas around the catch basin (i.e. place concrete around the catch basin). 3)Please provide rim and invert elevations for all pipes within the catch basins. 4)Typically, the footing drains cannot discharge to the stormwater management system. a.If the footing drains will discharge to the onsite stormwater management system, please provide engineering calculations showing that the system is designed for them. b.Otherwise, please show the footing drains discharging to a separate system (i.e. drywell, etc.).

DRY UTILITIES 1)Please remove any existing utilities. 2)Please show all proposed dry utilities(gas, phone, cable, etc.)on the plans so that utility separation can be verified. 3)On the proposed plans, the power does not meet the minimum separation of 3’ from sewer. Please revise the plans accordingly. 4)The City will not approve the PUD line to run within the City’s right-of-way, parallel to the property line. Please show the PUD line running straight from the pole into private property. Once on private property the line may run as needed. 5)Please add a note that all utilities must be underground. TESC and Grading Plan GENERAL 1)Please replace the silt fence detail and replace with the Edmonds Standard Detail E1.1. 2)Please replace the rock construction entrance detail and replace with the Edmonds Standard Detail E1.2 for a construction entrance. 3)Please add a note to the plans that filter socks will be added to any catch basins downstream from the construction site per Edmonds Standard Detail E1.3. Please resubmit 3 copies of the revised plansand associated documents with a written response to each item to a Permit Coordinator.
