In the event that any property owner fails, neglects, or refuses to comply with the provisions of §
446-2 within the time limit prescribed, the Borough may proceed immediately to clear or treat all snow and/or ice from the sidewalks or other designated areas with such costs chargeable to the property owner at the then-current rates prevailing for labor and materials plus an additional 10%, together with all charges and expenses. The Borough may file a municipal lien against the property in violation if such costs and expenses are not thereafter paid within 30 days, with any additional costs or expenses to file such lien also payable by the property owner, and/or the Borough may pursue civil proceedings to collect the same. The removal of snow or ice or the covering of ice by the Borough shall in no manner relieve the property owner from the imposition of penalties as herein provided.
